Conservation of Soil Moisture Using Mulch  of Green Bean Plants (Vigna Radiata)

The aim to this study was to determine the effect of plastic silver mulch and rice straw mulch on soil moisture conservation of green bean so that the plant can grow in dry season with enough water. The method used in this study was a randomized block design with three treatments: no mulch (T0), plastic silver mulch (T1) and rice straw mulch (T2). The parameters observed were physical soil of initial and final research, soil moisture measurements every 3 days, as well as growth and crop production parameters including plant height, number of seeds in pods, 100 seeds weight, sample plant production and total production. The results showed that the physical of soil analyzed were clay textured soil, preliminary porosity 60.77 and at the end of the study increased to 77.50%, organic matter 1.52%, initial bulk density 1.04 g/cm3 at the end of the study decreased to 0.60 g/cm3, soil permeability of 7.77 cm / hour and available water is 13.95%. The use of rice straw mulch from the beginning to the end of the study showed the best water content while the use of plastic silver mulch and no mulch showed water content not much different. The use of palstic silver mulch gives the highest yield of the best crops on 14 HST measurements where the plastic silver mulch differs markedly by the rice straw mulch and no mulch. The yield of green beans produced in the treatment of plastic silver mulch using the best results with a total production of 2.00 tons/ha, this result is significantly different from no mulch but not significantly different of rice straw mulch. Rice straw mulch is better used for soil conservation because it can improve soil aeration, retain water, prevent soil erosion, and increase organic matter on the soil.

Abstract Purpose Mulching is a practice recommended for soil moisture conservation in potato. The wheat straw and rice straw obtained as major crop residues were used as mulching materials to compare their effectiveness for soil moisture retention in potato crop. Methods The field experiments were conducted in a randomized complete block design replicated thrice with three treatments viz. plots incorporated with wheat straw mulch, rice straw mulch at the rate of 10 tonnes per hectare each and no mulch serving as control. The soil moisture was determined using a soil moisture probe and data were recorded daily at 10 cm, 20 cm and 30 cm soil depths. The Field Emission Scanning Electron Microscopy was used to investigate moisture retention characteristics of the mulch materials. Results Soil moisture retention varied as wheat straw mulch > rice straw mulch > no mulch at 10 cm, 20 cm and 30 cm soil depths, respectively. Highest moisture retention in wheat straw mulch at 10 cm depth is attributed to better moisture absorption ability of wheat straw in comparison to rice straw. Field Emission Scanning Electron Microscope images indicated the presence of smaller sized micro tubes in wheat straw than rice straw, which resulted in more water retention, thereby substantiating the findings of the study. Conclusion Wheat straw mulch is more effective than rice straw mulch for shallow rooted crops like potato, due to better moisture absorption and retention in upper soil layer.

Acid Sulphate

Organic matter has a function to maintain reductive conditions and to chelate toxic elements in acid sulphate soils. The study aimed to assess the dynamics of ferrous iron (Fe2+) in acid sulphate soil and its correlation with soil redox potential (Eh) and plant growth. The experiment was arranged in two factorial randomized block design with three replications. The first factor was two types of organic matter: (1) control (without organic matter), (2) rice straw and (3) rush weed (Eleocharis dulcis). The second factor was time of decomposition of organic matter: I1 = 2 weeks, I2 = 4 weeks, I3 = 8 weeks, and I4 = 12 weeks (farmer practice). The results showed that concentration of ferrous iron in the soil ranged from 782 to 1308 mg kg-1 during the rice growing season. The highest constant rate of iron reduction (k F2+) was observed on application of rice straw and rush weed with decomposition time of 8 weeks with the k Fe2+ value of 0.016 and 0.011 per day, respectively, while the ferrous iron formation without organic matter had the k Fe2+ value of 0.077 per day. The ferric iron (Fe3+) reduction served as a function of soil Eh as indicated by the negative correlation of ferrous iron and Eh (r = -0.856*). Organic matter decreased exchangeable iron due to chelating reaction. Iron concentration in roots was negatively correlated with soil soluble iron (r = -0.62*). Application of rice straw decomposed for 8 weeks increased the height of rice plant up to 105.67 cm. The score of Fe2+ toxicity at 8 weeks after planting ranged from 2 to 3, so rice crop did not show iron toxicity symptoms.

Straw Mulch

Organic crop production, whether for export or local consumption, is increasing to avoid the residual effects of synthetic herbicides in foods, soil, and water, toxicity to other nontarget organisms, and herbicide-resistant weed populations. Organic farmers consistently ranked weed management as one of their most important production problems. Therefore, a 2-year study was conducted under 15-year-old mandarin trees to compare the effects of rice straw mulch, cattail mulch, black plastic mulch, hand hoeing, cultivation, glyphosate, and unweeded control treatments on weed control, fruit yield, and fruit quality. The greatest control (94%–100%) of weeds occurred with the plastic mulch (200 or 150 μm) and three mulch layers of rice straw or cattail. Covering soil with cattail or rice straw mulch (two layers) gave 85% to 98% control of weeds. Uncontrolled weeds in the weedy control caused significant reduction in yield and fruit quality and decreased the yield/tree by 62% compared with hand hoe treatment. Plastic mulches of 200 and 150 μm, cattail (Cyprus articulatus L.) mulch (two or three layers) and two mulch layers of rice (Oryza sativa L.) straw treatments significantly increased the fruit yield/tree by 24%, 18%, 20%, 11%, and 12% more than cultivation treatment, respectively, without significant differences among these superior treatments. Soil mulching with three layers of rice straw, cultivation, glyphosate, and 80-μm plastic mulch treatments caused a significant reduction in weed density and weed biomass, but gave lower yield than superior treatments. Total soluble solids of fruits was unaffected by any of the weed management strategies, whereas values of total acidity and vitamin C were significantly lower in the unwedded control than most weeded treatments. These results demonstrate that two layers of cattail or rice straw mulch could be used effectively for controlling weeds in citrus groves. Their effectiveness in controlling weeds may increase their use in agriculture systems with a concomitant decrease in the need for synthetic herbicides. Further studies are needed to evaluate their side effects on beneficial organisms, diseases, and insects.

The assessment of abattoir effluent on the physicochemical and microbiological properties of the soil cultivated with flint maize was conducted in the Teaching and Research Farm of Ambrose Alli University, Ekpoma. The experiment was a randomized complete block design (RCBD) with five levels of abattoir effluent (0, 32 x 103, 64 x 10 3, 96 x 103, 128 x 103L/ha) and each was replicated three times. The effluent was collected and analyzed for its chemical properties, the number and types of bacteria and fungi before and at the end of the experiment. Soil samples were collected before planting and at the end of the experiment and analyzed for physicochemical properties as well as the number and types of bacteria and fungi. Maize variety; Samma – 38 was used as a test crop. Results showed that more bacteria and fungi counts were found in the abattoir effluent than in the soil. At 15 weeks after application, the plot treated with 64 x 103 L/ha of abattoir effluent had more bacteria isolated and the least bacteria count. The plot that received the 32 x 103L/ha had the least fungi count. The soil was slightly acidic except for the strongly acidic control. The soil after the applications of abattoir effluent was high in organic matter. Abattoir effluent increased the total N, K, Mg, and Ca with the highest recorded at the applications of 96 x 103L/ha and 128 x 103L/ha. Organisms such as Penicillium and Aspergillus spp were isolated, and these enhanced nitrogen and phosphorous fixation, thereby increasing soil fertility for suitable crop production.

ABSTRAK Nilam (Pogostemon cablin Benth) merupakan salah satu tanaman penghasil minyak atsiri yang dikenal dengan minyak nilam (patchouli oil). Salah satu kendala dalam pengembangan tanaman nilam adalah peka terhadap kekurangan air. Perubahan iklim cenderung menyebabkan lebih sering terjadi kekeringan di sejumlah wilayah termasuk Indonesia sehingga dalam pengembangan tanaman nilam diperlukan varietas toleran terhadap cekaman kurang air. Terdapat tiga varietas unggul nilam (Tapaktuan, Sidikalang, dan Lhokseumawe) dengan produksi minyak (290-375 kg/ha) dengan kadar patchouli alkohol 32–33%. Penelitian bertujuan untuk mengevaluasi respon fisiologis 4 varietas/aksesi tanaman nilam terhadap cekaman kurang air. Penelitian dilaksanakan di rumah kaca di Bogor pada tahun 2012. Penelitian menggunakan RAK faktorial dengan tiga ulangan. Faktor pertama 4 varietas/aksesi nilam (V) yaitu Sidikalang, Lhokseumawe, Tapaktuan, dan Bio-4. Faktor kedua empat interval penyiraman (W) yaitu 1, 3, 6, dan 9 hari sekali. Evaluasi pengaruh cekaman kurang air dilakukan terhadap beberapa karakter fisiologi tanaman nilam. Pengamatan dilakukan antara lain terhadap peubah kadar lengas tanah, konduktivitas stomata (Gs), laju transpirasi (Tr), kandungan air nisbi (KAN), potensial air daun (PAD) dan kandungan prolin daun. Hasil penelitian menunjukkan bahwa terjadi penurunan kadar lengas tanah, konduktivitas stomata, laju transpirasi, dan KAN pada semua varietas, sedangkan PAD dan kadar prolin meningkat seiring dengan semakin lamanya interval penyiraman. Kadar prolin tertinggi pada interval 9 hari sekali pada varietas Sidikalang. Tidak terdapat perbedaan respon varietas/aksesi nilam yang diuji. Kata kunci: Pogostemon cablin Benth, cekaman kurang air, karakter fisiologis.ABSTRACT Patchouli (Pogostemon cablin Benth) is one of plant that produces patchouli oil call patchouli oil. However, patchouli is susceptible to drought. The effect of global warming which changes rainfall pattern caused droughts in several regions including Indonesia. Therefore, it is important to find patchouli variety which is relatively tolerant to drought. Tapaktuan, Sidikalang, dan Lhokseumawe are three varieties of patchouli which produce high essential oil (290-375 kg/ha) with high patchouli alcohol content (32–33%). The objective of this research was to evaluate the physiological responses of four varieties/clone of patchouli to drought. The experiment was conducted at greenhouse at Cimanggu, Bogor from February to July 2012. The research was designed in randomized factorial block design (RBD) with three replications. The first factor was four varieties/clone of patchouli (V) Sidikalang, Lhokseumawe, Tapaktuan, and Bio-4. The second factor was four watering intervals (W) every 1, 3, 6 and 9 days of watering. Parameters evaluated were physiological characteristics, soil moisture content, stomatal conductance, transpiration rate (Tr), leaf water potential, relative water content, and proline content of leaf. The results showed that soil moisture content, stomatal conductivity, transpiration rate and relative water content decreased, while leaf water potential and proline levels increased along with the increase of watering intervals. The highest proline level was at interval of nine days watering treatment on Sidikalang varieties. However, all varieties/clone have not different responses to water deficit.

Present study was conducted to investigate the effect of different mulching materials on soil hydrothermal environment and plant growth parameters for potato crop at field experimental station of National Institute of Technology, Hamirpur in the humid sub-tropical agro climate of Western Himalayas. The field experiments were conducted in a randomized complete block design with four mulching treatments; wheat straw mulch, pine needle mulch, rice straw mulch and no mulch in three replications. An increase in soil moisture retention ranging from 5.14% to 42% was observed depending upon the mulch material and depth of the soil layer in root zone. Mulching also reduced the daily maximum soil temperature up to 3.5ºC with an average temperature reduction of 1-2ºC during the period of tuber formation. Mulching produced beneficial effects on root depth, plant height, leaf area index and tuber yield. Mulching helped to bring about a yield surplus of 1.7-4.4 tonnes ha-1 over unmulched conditions and an increase in water use efficiency which varied from 13.5% in rice straw mulch to 34.9 % inwheat straw mulch.

The aim of our research was to conduct a monitoring study of nitrate content in plant products of Uzhgorod district and to accomplish comparative analysis of the survey results in different periods of crop ripening. Selection of vegetable samples was carried out in Uzhgorod district in the early spring and summer periods. Determination of the nitrate content was performed using an ion-selective method at the Chemical and Toxicological Department of the Regional State Veterinary Medicine Laboratory in the Transcarpathian region of Ukraine. Vegetables were tested for nitrate content using the ion-selective method with the laboratory ion meter AI-123. Core investigation samples were crushed and homogenized. A 10.0 g weight of the investigated product, which was prepared according to MIR № 5048-89, was placed in a flat-bottomed or a conical flask, which was then filled with 50 cm3 potassium alumens solution and shaken in a shaking-machine for 5 minutes and then transferred into a measuring glass. The nitrate weight fraction in milligrams per kilogram was obtained together with the weight concentration value of nitrate ions in solution. For our study we selected vegetables grown in both public and private gardens of Uzhgorod district, namely: common onions, radishes, garden parsley, cucumbers, tomatoes, bell peppers, white cabbages, carrots and table beets. 25 samples were selected for each type of vegetable. Nitrate content was determined in the early spring growing period (from February 9 to May 27, 2011) and in the summer growing period (from June 3 to September 28, 2011), because in these particular periods we recorded the most frequent cases of food poisoning from nitrates among the population of the region. A clear trend has been traced towards increasing the nitrate content in food plant production, at levels which exceed the maximum permissible concentration (MPC). The results of our research demonstrate that the nitrate content exceeded the maximum permissible concentration in 9 kinds of vegetables out of the 11 selected for the investigation, which composes 82% of total production. In particular, among the selected vegetables an excess of nitrate content, above MPC was recorded in 100% of cucumbers, 92% of carrots, 40% samples of green onions, 40% of radishes, 40% of tomatoes, 28% bell peppers, and 16% of early white cabbages. However, the most significant nitrate excess, which was more than double the MPC, was observed in 56% of cucumbers, 20% of tomatoes, 8% of radishes in the early spring period and 4% of tomatoes in the summer period. Consequently, it has been established that the consumption of early vegetable production contributes to the ingestion by humans of significant amounts of nitrates. The application of an agrochemical system based upon sound measurement of the nitrate content would allow us to solve the task of increasing soil fertility and to form a deficit-free and positive balance of biogenic elements and humus in the "soil – plant – fertilizer" system and develop a system of crop production which is balanced in its chemical composition and nutritional value. To sum up, detailed determination of the factors that lead to the accumulation of nitrates in vegetable crops and the development of methods to reduce nitrate concentrations in crop production require further investigation.

ABSTRACT The present study evaluated soil moisture (θ) in forage cactus plantations under resilience practices such as irrigation, mulching and intercropping with sorghum. The experiment was arranged in a randomized block design with five water availability conditions (0, 8.75, 17.5, 26.25 and 35% of the reference evapotranspiration), and three planting systems: forage cactus exclusive system (PE), forage cactus with mulch (PC) and intercropping between forage cactus and sorghum (PS). Water content was measured until a depth of 0.60 m. Meteorological data were recorded between June 2012 and June 2013. Water content was not affected by different resilience practices and the variation coefficient was low to medium (4.0 to 22.1%). The temporal variation of soil moisture was more affected by the changes in rainfall, while the physical properties (soil density, porosity and grain size) were decisive in the vertical variation. It was concluded that periods with rainfall events favor the alternation of practices to improve forage cactus resilience (irrigation, mulch and intercropping).
