Effects of different media on the growth and yield of Swiss chard (Beta vulgarisvar. cicla) grown in hydroponics

Decline in the availability of suitable land and good fertile soil for vegetable production due to climate change, urbanisation and increasing population has resulted in studies to find alternative media that can be used to grow high value crops such as Swiss chard. The experiment was conducted at the Horticulture Department Greenhouses of the University of Eswatini, Luyengo Campus to determine the growth and yield of Swiss chard using different growing media. The treatments were laid out in a Randomised Complete Block Design (RCBD) and replicated four times. The media treatments consisted of sand, sawdust and mixture of sand and vermiculite (1:1). The results showed that Swiss chard grown in sawdust performed better than those in the other growing media and gave significantly (P<0.05) higher fresh yield (227.7 g/plant), root length (25 cm/plant) and the highest chlorophyll content (48.9µmol m2). Plants grown using sand had the lowest fresh yield (58.3 g/plant), root length (11.9 cm/plant) and the chlorophyll content (17.49 µmol m2). The results showed that Swiss chard production in hydroponics using sawdust resulted in higher yields and therefore should be recommended to farmers for use. Not only is it the best in production of Swiss chard but it is also readily available at low cost and re-usable provided it is treated.

Protective Structures

Leafy vegetable production in the Philippines is less diversified than many other countries, especially those used in salads. As a result, Filipino farmers are less familiar with production of leaf-type lettuce that is increasing in popularity with consumers. Therefore, two separate experiments were conducted simultaneously in open field and under bamboo house-type protective structures roofed with plastic to evaluate the performance and profitability of different leaf-type lettuce cultivars. Each study was carried out in randomized complete block design with five treatment cultivars and three replications. Most cultivars grown under protective structures had higher marketable yields than those grown in the open field. Despite plants grown under protective structures incurring higher production costs compared to the open field, higher marketable yields under protective structures resulted in higher net returns. Among the five cultivars, Green Span gave the highest return in the open field and Green Tower under the protective structure. Smaller lettuce cultivars produced lower yields than bigger cultivars.

Curly red chili (Capsicum annum L.) is widely cultivated us-ing inorganic fertilizers which causes high production costs. Chili is valued because of the level of spiciness. The level of spiciness of chili is determined by the level of capsaicin which is affected by nutrients in the growing media. The nutrient of the planting media can be fulfilled by degrading the growing media by microbes in organic fertilizer. One type of organic fertilizer containing degrading microbes is biofertiliz-er. Biofertilizer and biogas sludge is one of the organic fertilizers con-taining microbes and organic materials that are able to support nutri-ent levels of the planting medium. This study aimed to analyze growth parameters include chlorophyll content and measure capsaicin levels in curly red chili. Which given biofertilizer and biogas sludge in vari-ous dosage and determine the optimum dose of the fertilizer. The study was conducted at an agricultural demonstration plot in Wukirsari Vil-lage, Cangkringan, Sleman. The study design used RCBD (Randomized Complete Block Design), the data were analyzed by ANOVA (Analysis of Variance followed by Duncan’s Multiple Distance Test (DMRT) at the 95% confidence level. The highest growth parameters and capsa-icin content were obtained on curly red chili plants which were given biogas sludge 36 mL + biofertilizer 10 L / ha. The application of bi-ofertilizer and biogas sludge in various concentrations given has not been able to increase the average total chlorophyll content of curly red chili plants. Thus, it can be concluded that the most appropriate dose of curly red chili is 36 mL biogas sludge + 10 L bio fertilizer/ha

Mississippi is one of the nation's largest broiler litter producing states. Interest in using litter and other organic waste products, such as compost, in horticultural systems is increasing in the state and region. The objective of this research was to determine the influences of composted broiler litter (CBL) on three aspects of vegetable crop productivity: growth and yield, microbiological safety, and mineral nutrition. This report focuses on the first two objectives. Compost was made in a covered, turned windrow for a blend of broiler litter and hardwood sawdust. Responses to CBL were tested in two vegetables: collard (Brassica oleracea var. Acephala) and tomato (Lycopersicon esculentum). Rates of CBL ranged from 0 to 5 tons/acre, preplant incorporated in a randomized complete block design with four replicates for each species in two separate experiments in 2004. Testing of the CBL, the soil after application, leaves, and harvested organs found no significant influence of CBL on pathogenic microbe concentrations. At each of five sampling dates through commercial crop maturity, collard (Brassica oleracea var. Acephala) fresh and dry weight per plant increased linearly with CBL applications up to 5 tons/acre. Tomato (Lycopersicon esculentum) shoot fresh weight increased with increasing CBL applications at each sampling date. Marketable fruit yield increased linearly with increasing CBL applications. Total fruit yield response to CBL was best described by a quadratic equation.

Lettuce is a type of vegetable that is very popular with the people of Indonesia. It contains healthy nutrients including minerals, vitamins, antioxidants, potassium, iron, folate, carotene, vitamin C and vitamin E. Biostimulants has the ability to stimulate new root formation, improve plant root systems, increase the number of tillers, and increase yield. Biostimulant concentration and site of administration play a role in providing nutrients for the needs of lettuce plants. To obtain the right concentration and place of administration for the growth and yield of lettuce, the experiment was carried out using a 2-factor Randomized Block Design. The first factor was the concentration of biostimulants (K) with 6 levels of concentration including: K0 (without giving biostimulants), K1 (giving biostimulants at a concentration of 1 mL/L of water), K2 (giving of biostimulants at 2 mL/L of water), K3 (giving biostimulants at 3 mL/L of water). K4 (giving biostimulant at 4 mL/L water), K5 (giving biostimulant at 5 mL/L water). The second factor was the site of administration (T), namely: T1 (through the leaves) and T2 (through the soil). The interaction between biostimulant concentration and administration gave a very significant effect on leaf number, crop fresh weight, root length and root number. Biostimulant concentration (K) gave the percentage of plant growth in the variables of plant height (34.29%) and leaf area (47.34%). Place of administration (T) gave percentage of plant growth the variables of leaf area (21.08%) and root wet weight (0.52%). The interaction of biostimulant concentration and administration place (K x T) gave the percentages of plant growth variables of leaf number (15.5%), plant fresh weight (52.33%), root dry weight (2.30%), root length (16.53%), and root number (108.5%). The best treatment in this study was the provision of biostimulant at a concentration of 2 mL/L of water that was given through leaves.

Growing vegetable crops such as lettuce, on Ultisol soil has several obstacles, such as insufficient organic matter and nutrients in the soil. The provision of biochar and POC leri or organic fertilizer from rice washing liquid is expected to be a long-term and sustainable solution. This study was intended to test the addition of biochar to the growing media and the application of leri on lettuce cultivation. This study used a factorial Randomized Block Design (RAK) method. The first factor was the application of biochar to the planting medium (M), which consisted of M1: Ultisol without biochar and M2: Ultisol + 30 g biochar. The second factor was the administration of liquid organic fertilizer (LOF) leri (P), with 5 treatments consisting of P0: without giving LOF leri, P1: giving LOF leri without fermentation once a week, P2: giving LOF leri without fermentation twice a week, P3: giving fermented LOF leri once a week, P4: giving fermented LOF leri twice a week. The results of this study were tested statistically by analysis of variance, with the F test; if there was a significant difference, it was continued with the BNJ test (Honest Significant Difference) at a 0.05 level. The results showed that the best treatment of LOF leri in increasing lettuce growth and yield was 25% fermented LOF leri given 2 times a week, at 250 mL per lettuce plant. As a single treatment the best growing media was M2 (Ultisol soil + 30 g of biochar) with a plant height of 25.80 cm and the leaf number of 12.83; whereas the best LOF leri treatment was P4 (fermented LOF leri given twice a week), with a plant height of 30.27 cm and leaf number of 14.42. Based on whole plant fresh weight, the best treatment was the M2P4 (Ultisol + biochar growing medium and fermented LOF leri given week), which was 185.99 g per plant.

Swiss chard (Beta vulgaris var. cicla) is a leafy vegetable that belongs to the Chenopodiaceae family. The leaves are cooked, if still tender they are used in salads. Over the years, Emawati have adopted the use of inorganic fertilizers as they are easy to apply and come with recommended application rates. However, their main drawback is that they are environmentally unfriendly especially when washed into rivers, streams and other water bodies. For this cause, the use of animal manures has been promoted. Four-week-old Swiss chard seedlings were transplanted on the 4th of February, 2016 in 1.5 x1.5 m plots with an inter and intra row spacing of 45 cm and they were irrigated twice a day during the first week and every second day from the second week until the end of the experiment. The experiment was conducted at the Horticulture Department Farm, Faculty of Agriculture and Consumer Sciences, Luyengo Campus of the University of Swaziland to determine the effects of chicken manure application rates on growth, yield and quality of Swiss chard. Four chicken manure application rates (10, 20, 40 and 80 t/ha) and a recommended 900 kg/ha, inorganic basal fertilizer with a 125 kg/ha LAN top dressing fertilizer used as a control. A Randomised Complete Block Design (RCBD) with four replicates was used. The study showed that the application of 80 t/ha of chicken manure improved the growth and yield of Swiss chard. It is recommended that farmers may use 80 t/ha of chicken manure because it gave the best results compared to the other treatments. The highest fresh shoot mass (237.5 g) was obtained in plants treated with 80 t/ha of chicken manure while the lowest fresh shoot mass (100.0 g) was obtained in plants fertilized with inorganic fertilizers. It was concluded that 80 t/ha was the best under the conditions of this study and it was found that fresh mass at the end was the most important parameter to consider.

When moisture conditions in soil are suitable, the husk tomato has good vegetative growth and high yield. The objective of this work was determine the minimum available moisture level to obtain the highest yield, and establish an irrigation calendar. Treatments evaluated were: 15%, 30%, 45%, and 60% of moisture reduction in soil, according to the gravimetric method, in a randomized complete-block design with four replications. The variance analysis and Duncan test were carried out at a 0.05 level of probability for following variables studied: Fresh fruit yield (kg/ha), plant height, root length, and fruit diameter. The results show that a 30% reduction moisture level was remarkable with a 28,610.67-kg/ha yield of fresh fruit. In relation to agronomics characteristics, the results show that, for plant height, root length, and fruit diameter were remarkable with the 15% and 60% reduction moisture, respectively. This was due to the greater interval of irrigation and tendency of root system to search for moisture. The greater vegetative growth and yield is with a moisture level of 65% to 80% present in soil, indicating that the husk tomato tolerates this 30% of reduction moisture, with higher values producing more stress in plants and modifying the vegetative growth and production.

Abstract Low soil fertility is a major problem limiting peri-urban vegetable production in the Kumasi metropolis. This study was conducted to assess the effects of poultry litter biochar (PLB) and NPK fertilizer application on soil chemical properties and the yield of cabbage. Twelve treatments (control, 100% NPK, 50% NPK, 2.5 t ha−1 PLB, 2.5 t ha−1 PLB + 50% NPK, 2.5 t ha−1 PLB + 100% NPK, 5 t ha−1 PLB, 5 t ha−1 PLB + 50% NPK, 5 t ha−1 PLB + 100% NPK, 7.5 t ha−1 PLB, 7.5 t ha−1 PLB + 50% NPK, and 7.5 t ha−1 PLB + 100% NPK) were evaluated under field conditions in a randomized block design with three replications. Combined application of PLB and NPK fertilizer improved the soil chemical properties, growth, and yield of cabbage relative to the control and sole PLB treatments. Application of 5 t ha−1 PLB + 50% NPK increased the soil pH, soil organic carbon, available phosphorus, and cation exchange capacity by 26.6, 41.4, 296, and 78.7%, respectively, relative to the control. Moreover, 5 t ha−1 PLB + 50% NPK increased the cabbage yield by 73% compared with the control. This study concludes that PLB and NPK fertilizers can be applied to improve the soil chemical properties and yield of cabbage.
