Abstract:A field experiment was conducted at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat, India during
kharif season of the years 2022-23 to study the impact of different organic sources on productivity and economics of soybean under middle Gujarat condition. The experiment was comprised of twelve treatments of different organic sources supplying 100%, 75% and 50% N through different combinations of farm yard manure (FYM), vermicompost (VC) and poultry manure (PM), seed treatment and soil application of Bio NP consortium,
Jeevamrut (soil and foliar application) and
ghanjeevamrut compared with control treatment. The experiment was laid in the loamy sand textured soil found medium in organic carbon, available nitrogen and phosphorus and high in available potash.
Application of 50% N through FYM + 50% N through VC + Jeevamrut soil and foliar application registered significantly higher plant height and number of branches/plant at 60 DAS and at harvest, dry matter accumulation and number of pods/plant at harvest. The same treatment produced significantly higher seed yield (1518 kg/ha) and haulm yield (2454 kg/ha) of soybean. Maximum net realization of ₹ 74353/ha was recorded under application of 50% N through FYM + 50% N through VC + Jeevamrut soil and foliar application with BCR of 3.02, followed by treatment with 250 kg/ha FYM + 250 kg/ha ghanjivamrut + 500 L/ha Jeevamrut (soil and foliar application) with net realization of ₹70157/ha and BCR of 3.40.
