Abstract:
Field experiments were carried out during rabi seasons of 2017-18 and 2018-19 at the Agronomy Instructional Farm, Sardarkrushinagar to study the effect of Bio NP consortium and Fe and Zn application on yield, economics nutrient content and uptake by wheat. Twelve treatment combinations comprising of two treatments of biofertilizer and six treatments of nutrients were laid out in factorial randomized block design with four replications. The experimental soils were loamy sand in texture, low in organic carbon, available N and DTPA-extractable Fe and Zn. Pooled results revealed that combined application of soil drenching of bio NP consortium @ 1L ha^-1 + 100% RDNP and 5.00 kg Fe and 2.50 kg Zn ha^-1 (B₂N₃) registered significantly higher grain and straw yield, P content in grain, N uptake by grain and Fe uptake by straw but it remained at par with treatment combination B₂N₄ only. The highest gross (₹ 1,30,267 ha^-1), net realization (₹ 92,905 ha^-1) and BCR value 3.49 of wheat crop was incurred from same treatment combination B₂N₃.
