Abstract:
A field experiment was conducted during kharif season of 2020 at Agricultural Research Station, Ummedganj, Kota (Rajasthan) to evaluate the Effect of Irrigation Schedules and Soil Amendments on growth and nutrient content & uptake of Soybean under Vertisols of South-Eastern Rajasthan”. The experiment was laid out with twelve treatment combinations, which is consisting of three levels of irrigation schedules (0.6 (I1), 0.8 (I2) and 1.0 (I3) IW/CPE ratios) as a main plot treatments and four soil amendments (No soil amendments (S0), wheat straw (S1), mustard straw (S2) and Compost @ 5 t ha^-1) as sub plot treatments tested under strip plot design with three replications. The pooled data revealed that the increasing levels of irrigation schedules and different soil amendments increased the plant height, dry matter accumulation, number of nodules per plant as well as content and uptake of nitrogen, phosphorus and potassium in seed and straw. The significantly highest increase in growth parameter and nutrient content and uptake was observed under the treatment I3 (Irrigation schedules @ 1.0 IW/CPE ratio) with S3 (Compost @ 5 t ha^-1), Therefore, in this tract for soybean, the application of irrigation schedules @ 1.0 IW/CPE ratios with compost @ 5 t ha^-1 as a most profitable dose is being recommended for higher seed yield and net returns per hectare in Vertisols of South-Eastern Rajasthan.
