Earth-Kind® Vegetable Production in the Home Garden Using Mushroom and City Compost

A field study was conducted in 2010 and 2011 to determine the suitability of Earth-Kind® production principles for home vegetable gardening. Earth-Kind® production encourages water and energy conservation, and reduction of fertilizer and pesticide use. Seven vegetable cultivars [Sweet Banana and bell pepper (Capsicum annuum); Celebrity and Juliet tomato (Solanum lycopersicum); Spacemaster cucumber (Cucumis sativus); Ichiban eggplant (Solanum melongena); Spineless Beauty zucchini (Cucurbita pepo)] were grown in mushroom compost (MC) or city compost (CC). Both composts were incorporated preplant into the soil with shredded wood mulch placed over them. In each year, nitrogen (N) fertilizer (15.5N–0P–0K from calcium nitrate) was applied preplant to CC plots to bring initial soil fertility levels similar to MC plots. No additional fertilizer was applied during the growing season. Drip irrigation was supplemented weekly. One application each of neem oil and pyrethrin (organic insecticides) and chlorothalonil (synthetic fungicide) was applied before harvest in 2010, but none was applied in 2011. Results indicated that Earth-Kind® technique could be effectively implemented in a home vegetable garden. MC is better suited for Earth-Kind® vegetable production than CC for some vegetables. Banana pepper, bell pepper, and zucchini had twice the yield in MC plots when compared with CC plots. No yield differences (P > 0.05) were observed between composts for tomato, eggplant, or cucumber. With proper irrigation and soil preparation practices such as addition of compost and mulch, Earth-Kind® vegetable gardening techniques can be used for selected vegetable crops without additional N fertilizer or pesticides. Furthermore, Earth-Kind® vegetable gardening can be successful as long as the home gardener understands that low yields may result from using this production method. However, often the home gardener is more concerned about producing vegetables using sustainable, environmentally friendly methods than maximizing yields.

Serious Disease

Phytophthora blight, caused by Phytophthora capsici, is a serious disease in vegetable production, and selective use of fungicides continues to be a significant component of disease management programs. The effect of three chemical compounds—mandipropamid, dimethomorph, and cyazofamid—on asexual stages of P. capsici collected from bell pepper and cucurbits in Georgia was assessed in this study. Forty isolates of P. capsici were determined to be sensitive to mandipropamid and dimethomorph based on mycelial growth, zoospore germination, and sporangial production. Concentrations that were 50% effective (EC50 values) of mandipropamid that inhibited mycelial growth, zoospore germination, and sporangial production of the isolates averaged 0.03, 5.70, and 0.02 μg/ml, respectively. EC50 values of dimethomorph in inhibiting mycelial growth, zoospore germination, and sporangial production averaged 0.24, 0.10, and 0.46 μg/ml, respectively. The majority of isolates were either resistant or intermediately sensitive to cyazofamid at 500 μg/ml or lower concentrations based on mycelial growth or sporangial production, although all the isolates were sensitive to this compound based on zoospore germination, with an average EC50 of 0.04 μg/ml. The results indicated that P. capsici populations in Georgia have not developed resistance to mandipropamid and dimethomorph whereas, for the majority of the isolates, certain asexual stages were resistant to cyazofamid.

Foliar Micro-nutrition is the application of micronutrients to plants by spraying directly onto their leaves. Although it is not economical to spray macronutrients and micronutrients through foliar spraying, researchers prefer soil application for macronutrients and foliar applications of micronutrients. Several researches have demonstrated that the method which is used to deliver the required micronutrient in appropriate concentration to improve nutrient status along with increased yield and quality potential are adapted by combining applications of FeSO4 at a dose of 0.2%, Calcium nitrate at 0.2%, Boron at 0.1% and ZnSO4 at 0.2% has revealed a 51% increase as compared to control in potato. Application of ZnSO4 (0.4%) and ZnSO4 (0.6%) provides significant impact on growth and yield characteristic of Chilli; Zinc Sulfate (0.5%) and Borax (0.5%) also shows better result on the number of fruits per plant, fruit length, fruit diameter and yield per plant in Eggplant. Applying ZnSO4 (0.5%) shows better results on plant height, weight of head and yield of head in cabbage cultivations. Combined application of Boron (100 ppm) + Molybdenum (50 ppm) along with 60 kg/fed of Nitrogen. The results showed increased 38.02% on curd yield of cauliflower over control. A study reveals that application of (0.5%) Zn+ (0.1%) B along with 75 kg/ha of potassium in combination showed 31.73% increases yield of watermelon. Application of boron at 0.25% and zinc 0.5% showed a 31.17% increase in the total onion yield. The combined application of MgSO4 (0.5%), MnSO4 (0.5%), FeSO4 (0.5%) and ZnSO4 (0.5%) has increased yield of okra 31.8% over control. In general this critical review lays an emphasis from the review point of that micronutrients have been found to show satisfactory results than control conditions and has an immense potential in vegetable production to increase yield attributes.

The cost of transporting manure can affect profit. Manure was applied either annually or biennially to bell pepper (Capsicum annuum L.), cv. Jupiter, cucumber (Cucumis sativus L.), cv. Earli Pik, and sweet corn (Zea mays var. rugosa Bonaf.), cv. Incredible (se endosperm genotype), produced using organic methods and compared with production of these crops using conventional methods and annually applied synthetic fertilizer. Conventional and organically maintained portions of the field were separated by a 25-m buffer zone planted with sweet corn, which was provided with manure. The experiment was conducted from 2005 to 2008 at Lane, OK. Nutrient contents of soil and edible portions were determined as were yields. Economic analyses comparing costs of production and profit were conducted. There were yield responses resulting from year. Bell pepper yield was little affected by type of fertilizer application. Cucumber and sweet corn benefited from use of manure over conventional fertilizer. There was no pattern of alternating increased or decreased nutrient content in edible portions or in the soil as a result of annual or biennial application of manure. Treatment with manure produced higher returns than did conventional fertilizer. Annual treatment with manure produced higher returns in bell pepper and sweet corn than did treatment with manure in alternate years; the opposite was true for cucumber. Annual application of manure appears to be necessary for most of the vegetable crops tested.

Phytophthora blight, caused by Phytophthora capsici, is one of the most destructive diseases in the production of solanaceous and cucurbitaceous vegetable crops. Fluopicolide has been used to control the disease; however, reduced efficacy of the fungicide was observed in Georgia. P. capsici isolates were collected from commercial vegetable fields in Georgia in 2018 and 2019 to determine sensitivity to fluopicolide, which were phenotyped to have 43.1% of the isolates as resistant. The fitness of resistant (R) and sensitive (S) isolates was assessed through mycelial growth and sporulation assays exposed to the fungicide (0 or 50 µg/ml). Fluopicolide did not reduce mycelial growth, sporangial production and zoospore germination of the resistant isolates. In the absence of fluopicolide, there was no significant difference between the R and S isolates in sporangial production, but mycelial growth and zoospore germination of the R isolates was greater than the S isolates (P = 0.01 and 0.001, respectively). The R isolates had similar ability as S isolates to induce disease on ‘Aristotle’ bell pepper, and most of the R and S isolates caused the same level of disease on ‘Paladin’. Inoculating squash fruit using different R:S ratios and recovering R and S isolates after 5 cycles of inoculation resulted in similar trends in changes of R vs. S isolates ratios. Overall it appeared that fitness and competitive ability of the R isolates were not reduced compared to the S isolates. This is the first report of the occurrence of field isolates of P. capsici resistant to fluopicolide in the world. The results have significant implications in providing guidance for growers to avoid or limit use of this fungicide in vegetable production.

Studies conducted on selected vegetable crops in replicated trials using nitrogen fertilizer at the specified rates equivalent to 56 kg, 112 kg, 224 kg, and 448 kg per hectare, produced yield variations. The purpose of this research was to compare the effects of nitrogen (ammonium nitrate) on vegetable production for the home gardener. The yield in numbers of U.S. No. 1 grade bell peppers treated at the rate of 224 kg was higher for the third harvest when compared to the individual yields of the 1st, 2nd, and 4th harvests. The accumulative weight and number of fruit were higher on pepper plants receiving 56 kg than those receiving greater amounts of nitrogen. Tomato yields were higher for the 3rd harvest of plants treated at the 56 kg rate when compared to the yield at greater rates. Maturity of tomatoes was delayed at the nitrogen rate of 448 kg per hectare. At the nitrogen rate of 56 kg, the 2nd harvest of snap beans recorded a higher yield than the individual yields of the other three harvests. Individual head weight of cabbage was the greatest when plants received 448 kg nitrogen as compared to plants treated with less nitrogen.

Poor water- and nutrient-holding capacity of sandy soils, combined with intense leaching rainfall events, may result in excessive N-fertilizers losses from vegetable production systems. Three cover cropping (CC) systems were used to assess supplemental N-fertilizer requirements for optimal yields of selected vegetable crops. Fertilizer N-rates were 0, 67, 133, 200, and 267; 0, 131, and 196; and 0, 84, 126,168, and 210 kg N/h for sweet corn (Zea mays var. rugosa), broccoli (Brassica oleracea), and watermelon (Citrullus lanatus), respectively. Crop rotations consisted of sunn hemp (Crotalaria juncea) in Fall 2003 followed by hairy vetch (Vicia villosa), and rye (Secale cereale) intercrop or a fallow. During Spring 2004, all plots were planted with sweet corn, followed by either cowpea (Vigna unguiculata) or pearl millet (Pennisetum glaucum), which preceded a winter broccoli crop. Hairy vetch and rye mix benefited from residual N from a previous SH crop. This cropping system provided a 5.4 Mg/ha yield increment for sweet corn receiving 67 kg N/ha compared to the conventional system. For the 133 N-rate, CC-based systems produced similar yields compared to conventional systems amended with 200 kg N/ha. Pearl millet accumulated 8.8 Mg/ha—but only 69 kg N/ha—and potential yields with this system were 16% lower compared to cowpea system. For a subsequent watermelon crop, trends were reversed, possibly due to a delay in mineralization for pearl millet. Because of its persistent growth after mowing, hairy vetch hampered initial growth and shading also delayed fruit development. Although CC may accumulate up to 131 kg N/ha actual N benefits, N-fertilizer benefits were only 67 kg N/ha, which may be related to a lack of synchronization between N release and actual crop demand.

Industry Standard

Home gardeners living in areas with alkaline water sources do not have easy or economically affordable means of acidifying irrigation water for vegetable production. One solution for achieving optimal vegetable yields using alkaline irrigation water is to grow the vegetables in a modified medium. To date, no medium on the retail market suits such growing needs. Therefore, medium recipes with varied levels (0, 4, or 8 lb/yard3) and sources of calcium [dolomitic lime, calcium sulfate (CaSO4)] and magnesium [dolomitic lime, magnesium sulfate (MgSO4)] were tested using an alkaline irrigation on ‘Oakleaf’ lettuce (Lactuca sativa), ‘Earliana’ and ‘Salad Delight’ cabbage (Brassica oleracea var. capitata), and ‘Snow Crown’ cauliflower (Brassica oleracea var. botrytis) crops. Additionally, crops were grown in two environments, under a high tunnel and on a nursery yard. High tunnel and nursery yard sites were used to test media performances in the presence of, and eliminating, rainwater to simulate container-grown vegetables growing in both a home garden situation and a commercial greenhouse production situation. The base mix of all media treatments in the study was 80 bark : 20 peat and fertilized with 12 lb/yard3 slow-release fertilizer at a rate of 1.8 lb/yard3 nitrogen (N), 0.5 lb/yard3 phosphorus (P), and 1 lb/yard3 potassium (K). This initial fertilizer application was incorporated to each medium before filling containers. Four treatments were tested against a commercially available medium, industry standard (IS) treatment (a commercially available bagged medium), and a control medium [treatment C (no supplemental calcium or magnesium fertilizer)] by supplementing the base mix with the following fertilizer levels: 4 lb/yard3 each of CaSO4 and MgSO4 (treatment 1); 4 lb/yard3 dolomitic lime (treatment 2); 4 lb/yard3 each of dolomitic lime, CaSO4, and MgSO4 (treatment 3); 8 lb/yard3 dolomitic lime (treatment 4). Media treatments 1 through 4 outperformed the IS and C media treatments in nearly all crops. All crops grown on the nursery yard, and cabbage grown under the high tunnel, had greater yields when grown in medium treatment 3, compared with the IS and C media treatments (P ≤ 0.05). All crops grown in medium treatment 2 on the nursery yard produced greater yields than the IS and C media treatments (P ≤ 0.05).

Степень технологической и технической зависимости отечественных производителей овощных культур от зарубежных производителей с.-х. техники, а также их техническая оснащенность специализированными машинами объясняется высокими затратами на производство овощей, особенно на уборку, что при общем дефиците ручного труда приводит к сокращению площадей, нарушению технологии выращивания и соответственно снижению урожайности. Цель исследований – определить современное состояние технологического и технического обеспечения производства овощных культур в Российской Федерации. Для достижения поставленной цели использовали методологию системного анализа и синтеза, математической статистики, численные методы решения аналитических зависимостей. Статистические исследования современного состояния технического обеспечения производства овощей в России могут служить основой для построения модели и разработки концептуальных принципов модернизации технологического и технического обеспечения работ в овощеводстве. Определена потребность товаропроизводителей в современных высокотехнологичных комплексах машин для производства овощных культур. Проведенные статистические исследования позволили оценить современное состояние с.-х. машиностроения по выпуску необходимого для товаропроизводителей количества машин. Повышение объемов производства овощной продукции неразрывно коррелирует с уровнем технического обеспечения отрасли овощеводства в целом, что подтверждает уровень локализации с.-х. машиностроения РФ, а также Беларуси и Казахстана, где с.-х. машиностроение представлено широкой номенклатурой предприятий, выпускающих комплексы машин от предпосадочной обработки почвы до послеуборочной обработки товарной продукции. Для возрождения с.-х. машиностроения и развития рынка средств механизации аграрного производства определены основные механизмы обновления парка сельхозтехники – преимущественно привлечением кредитных ресурсов коммерческих банков и лизинговых компаний. Кроме того, интенсивность ведения сельского хозяйства в современных условиях производства невозможна без высокого уровня насыщения машинно-технологических комплексов средствами интеллектуализации. Получать качественную конкурентоспособную продукцию можно только при использовании современных высокопроизводительных машин, обеспечивающих совмещение технологических операций, в конструкциях которых заложены системы автоматизированного управления технологическими процессами, учета почвенного плодородия, обеспечения экологической чистоты агроландшафтов. The degree of technological and technical dependence of domestic producers of vegetable crops on foreign producers of agricultural machinery, as well as their technical equipment with specialized machines, is explained by the high costs of vegetable production, especially for harvesting, which, with a general shortage of manual labor, leads to a reduction in area, disruption of cultivation technology and, accordingly, a decrease in yield. The purpose of the research is to determine the current state of technological and technical support for the production of vegetable crops in the Russian Federation. To achieve this purpose, we used the methodology of system analysis and synthesis, mathematical statistics, numerical methods for solving analytical dependencies. Statistical studies of the current state of technical support for vegetable production in Russia can serve as a basis for building a model and developing conceptual principles for modernizing technological and technical support for work in vegetable growing. The need of commodity producers for modern high-tech complexes of machines for the production of vegetable crops is determined. The conducted statistical studies made it possible to assess the current state of agricultural engineering for the production of the number of machines necessary for commodity producers. The increase in the production of vegetable products is inextricably correlated with the level of technical support for the vegetable growing industry as a whole, which confirms the level of localization of agricultural machinery in the Russian Federation, as well as in Belarus and Kazakhstan, where agricultural machinery is represented by a wide range of enterprises that produce complexes of machines from pre-planting tillage to post-harvest processing of commercial products. For the revival of agricultural machinery and the development of the market of agricultural production mechanization tools, the main mechanisms for updating the agricultural machinery fleet are determined-mainly by attracting credit resources from commercial banks and leasing companies. In addition, the intensity of agriculture in modern production conditions is impossible without a high level of saturation of machine-technological complexes with means of intellectualization. It is possible to obtain high-quality competitive products only with the use of modern high-performance machines that ensure the combination of technological operations, in the designs of which there are systems for automated control of technological processes, accounting for soil fertility, ensuring environmental cleanliness of agricultural landscapes. Key words: vegetable growing, vegetable seeders, transplanters, vegetable harvesting equipment.

A three-year experiment was conducted at the North Florida Research and Education Center-Quincy involving a crop rotation sequence of oats and rye (winter), bush beans (spring), soybean (summer) and broccoli (fall). Bush beans and broccoli were the cash crops. This paper presents analyses of the riskiness of organic production utilizing years in bahiagrass prior to initiating the crop rotation sequence and conventional tillage (CT) versus strip tillage (ST). Methods of “Risk-rated enterprise budget” and “Analyses of Variance-Covariance Matrix (ANOVA)” were utilized for determining relative profitability, and coefficient of variation was applied for measuring riskiness of each treatment. Three years of bahiagrass prior to initiating the crop rotation sequence, in combination with conventional tillage, had the highest profitability and ranked as the least risky scenario. The second most profitable treatment was conventional tillage with four years of bahiagrass. Focusing on strip tillage, four years of bahiagrass with strip-tillage ranked third in term of profitability.</span></p>

Для обеспечения населения РФ качественной, полезной и экологически безопасной овощной продукцией в требуемом количестве необходимо изучение потенциальной продуктивности новых сортов и гибридов овощных культур, применение современных элементов технологии и продуктов в области агротехнологий выращивания. Хороший вкус, высокое содержание ценных для человека витаминов, микроэлементов и органических кислот вывело сладкий перец в ранг наиболее популярных овощных культур. В мире выведено и культивируется огромное количество сортов сладкого перца. В нашей стране наиболее распространенным сортотипом является перец сладкий (Capsicum annuum), или болгарский. На обыкновенных черноземах Бирючекутской селекционной опытной станции (Новочеркасский район Ростовской области), имеющих слабощелочную реакцию среды, мощный гумусовый горизонт, среднюю обеспеченность подвижным фосфором и высокую обменным калием, в 2017–2018 годах была исследована потенциальная продуктивность перца сладкого гибрида Темп при высоком уровне обеспеченности растений влагой и питательными элементами. Оценено комплексное действие основного внесения расчетных доз минеральных удобрений, капельного орошения, трехкратной подкормки водорастворимыми удобрениями «Мастер» и органоминеральным наноудобрением «Арксойл» на урожайность и качество перца сладкого. Выяснено, что основное удобрение и подкормки влияют, в первую очередь, на число плодов на одном растении, увеличивая их в 2–3,3 раза при незначительном повышении массы плода. Установлено, что без применения минеральных удобрений при капельном поливе было получено 25–27 т/га плодов. Использование рекомендованной дозы удобрений N120P120K120 увеличило урожайность перца до 50,5 т/га, а комплексное применение основного удобрения с 3-кратной корневой подкормкой водорастворимым удобрением «Мастер» позволило получить урожайность перца до 64,8 т/га. Наиболее высокая продуктивность растений была получена при комплексном использовании расчетной дозы на урожайность 90 т/га в сочетании с корневой подкормкой – 86,8 т/га при хорошем качестве плодов перца. To provide the population of the Russian Federation with high-quality, healthy and environmentally friendly vegetable products in the required amount, it is necessary to study the potential productivity of new varieties and hybrids of vegetable crops, use modern elements of technology and products in the field of agricultural technologies. Good taste, high content of vitamins, microelements and organic acids valuable for humans have made sweet peppers one of the most popular vegetable crops. A huge number of varieties of sweet peppers have been bred and cultivated in the world. In our country, the most common cultivar type is bell pepper (Capsicum annuum) or Bulgarian. On ordinary chernozems of the Biryuchekutskaya selection experimental station (Novocherkassk district of the Rostov region), which have a weakly alkaline reaction of the environment, a powerful humus horizon, an average supply of mobile phosphorus and high exchangeable potassium, in 2017-2018, the potential productivity of sweet pepper the level of supply of plants with moisture and nutrients. The complex effect of the main application of the calculated doses of mineral fertilizers, drip irrigation, 3-fold top dressing with water-soluble fertilizers Master and organomineral nanofertilizers Arxoil on the yield and quality of bell peppers was evaluated. It was found that the main fertilization and feeding affect, first of all, the number of fruits per 1 plant, increasing them by 2-3.3 times with a slight increase in the weight of the fruit. It was found that without the use of mineral fertilizers with drip irrigation, 25-27 t/ha of fruits were obtained. The use of the recommended dose of fertilizers N120P120K120increased the yield of pepper to 50.5 t/ha, and the complex application of the main fertilizer with 3-fold root feeding with the water-soluble fertilizer Master allowed to obtain the yield of pepper up to 64.8 t/ha. The highest plant productivity was obtained with the integrated use of a calculated dose for a yield of 90 t / ha in combination with root feeding - 86.8 t/ha with good quality pepper fruits.
