Abstract:
Soybean being an important pulse as well as oil seed needs special mention to overcome crisis in edible oil production in the country. It is also called as “Gold of soil”. An experiment was conducted at College of Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during kharif (Soybean) and rabi (Amaranthus) season of the years 2019-20 and 2020-21. An agronomical investigation on effect of integrated nitrogen management in soybean and their residual effect on grain amaranthus under irrigated condition. There were ten integrated nitrogen management treatments arranged in Randomized Block Design with 4 replications. Integrated use of the organic and inorganic sources of plant nutrients on growth and yield attributes is very crucial for the assurance of food securities. Different observation on the crop parameters were carried out during course of investigation. All the growth and yield parameters viz., number of pods/plant, seed yield and straw yield were recorded significantly higher with application of 50% RDN through vermicompost + 50% RDN through inorganic fertilizer (T₃). Residual amaranthus crop, integrated nitrogen managements did not exert any significant response on plant height at 30 DAS. Significantly higher growth parameters viz., plant height at harvest, panicle length, spikelet length, grain yield and straw yield were recorded by application of 50% RDN through FYM + 50% RDN through inorganic fertilizer (T₂) during pooled of two years.
