Effect of foliar nutrition on soybean productivity

The field experiment was conducted in field at Regional Research Center, Amravati during kharif season to evaluate the effect of foliar spray of chemical nutrients on yield attributes and economics of soybean. Treatments comprising of RDF+water spray at pod initiation (T1), RDF+Urea 2% spray at pod initiation (T2), RDF+DAP 2% spray at pod initiation (T3), RDF+MOP 0.5% at pod initiation (T4), RDF+19:19:19 (NPK) 2% at pod initiation (T5), RDF+Molybdenum 0.5% at pod initiation (T6), RDF+Boron 0.5% at pod initiation (T7), RDF+Zinc chillated 0.5% at pod initiation (T8) and RDF only (T9). Yield attributes viz., branches plant-1, pods plant-1, seed index and seed yield Kg/ha and straw yield Kg/ha was recorded at the time of harvesting. Highest no. of pods per plant was observed in treatment RDF+DAP 2% at pod initiation stage (T3) i.e. 15.73 followed by T5 and T7. Seed and straw yield (1599 and 2131 kg/ha respectively) was recorded in treatment RDF+19:19: 19 (NPK) 2% at pod initiation stage (T5) but found at par with T2, T3 and T7.
