A field experiment was conducted to study the impact of Sulphur(S) and Phosphorus (P) on yield, nutrient status of soil and their contents in pigeonpea (Cajanus cajan) during the year 2008-2009. Seven treatments were studied in Factorial Randomized Block Design with three replications. The treatment combinations were derived from three levels of sulphur (0, 20 and 40 kg S ha(-1)) and four level...

The depletion of soil organic matter is one the major challenges constraining agricultural production in southern zone Mali. This study evaluated effects compost types, methods, and dose applications on productivity sustainability sorghum. Two types (farmer practice cotton stems) were applied to sorghum at two rates (microdosing 2.5 t ha−1 broadcasting 5 ha−1) 30 farmer fields 2019 2020. treatm...

The rice plant accumulates silicon (Si) in greater quantity, which varies among the genotypes. This study was conducted to determine optimum fertilization rate and its effect on growth, yield, yield attributes, soil nutrient uptake. Six different dioxide (SiO2) rates, including 0, 50, 75, 100, 125, 150 kg SiO2/ha, were applied initially. of SiO2 obtained by statistical analysis, utilizing analy...

The study was conducted to investigate the effect of nitrogen application on the yield contributing characteristics, biomass yield and nutritive values of cowpea forage. Five nitrogen levels viz: 0 (T0), 15 (T1), 20 (T2), 25 (T3) and 30 (T0) kg N/ha were applied in 20 plots in a Completely Randomized Design (CRD). The result showed that the application of nitrogen fertilizer had significant (P<...

in many crops, incorrect management of nitrogen and water is one of the most important factors in the resources productivity such as water and nitrogen. in order to evaluate the effects of different nitrogen levels (zero, 50, 100 and 150 kg ha-1) and irrigation application rates (100, 75 and 50% of water requirement per species) on corn, sesame and sugar beet, three separate experiments was con...

The experiment was conducted at Zonal Agricultural Research Station, Vishwesharaiah Canal Farm, Mandya during 2018-19 to study the nutrient uptake (NPK), use efficiency and grain yield of rice (Oryza sativa L.) in different establishment methods under varied management practices. laid out a split plot design with three replications. main comprised viz., semi dry rice, drum seeded transplanted w...

On a typical dairy farm today, large amounts of N are imported as feed supplements and fertilizer. If this N is not recycled through crop growth, it can lead to large losses to the atmosphere and ground water. More efficient use of protein feed supplements can potentially reduce the import of N in feeds, excretion of N in manure, and losses to the environment. A simulation study with a dairy fa...

Two cultivars each of four warm-season grass species under three N fertilizer treatments and three harvesting regimes were studied to determine the effect of nitrogen fertilizer and harvest date on forage yield. Research was conducted in eastern Nebraska on an alluvial soil. The eight grasses studied were 'Blaze' and 'PM-K-129' little bluestem [Schizachyrium scoparium (Michx.) Nash], 'Cave-in-R...

Research was carried out on the basis of preserved field multifactor experiment tea crop ( Camellia sinensis (L.) Kuntze) in conditions Sochi Black Sea coast. The application NPK fertilizers different doses and combinations according to experimental scheme annually from 1986 2011. Since 2012, use has been completely discontinued. fertility indicators long-fertilized brown forest acidic soils (i...
