tailieunhanh - Effect of nutrient management on nutrient uptake and economics of maize (Zea Mays L.) under different tillage practices

A field experiment was carried out during kharif season of 2016 at Research farm of Tirhut College of Agriculture, Dholi, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur (Bihar) to study the “Effect of nutrient management on nutrient uptake and economics of maize (Zea mays L.) under different tillage practices”. The experiment was laid out in split plot design with three replications. Main plot consist of three different tillage practices viz., a) Zero tillage (ZT) b) Conventional tillage (CT) and c) Bed planting (BP) and sub-plot comprised of four different level of nutrient management viz., a) Recommended dose of fertilizer (RDF) (120, 60 and 50 kg/ha N, P2O5 and K2O) b) Site Specific Nutrient Management (SSNM) based on nutrient expert and c) Farmers practice (FP) (150% of RDF + 10 ton FYM). Among the different tillage practices, bed planting recorded significantly higher gross returns (1,06,396 Rs/ha), net returns (64,111 Rs/ha) and total available nutrient uptake (N, P, K Fe and Zn) over rest of the tillage practices. Among the different nutrient management practices, SSNM recorded significantly higher net returns (63,523 Rs/ha), B: C ratio () and total available nutrient uptake (N, P, K Fe and Zn) over rest of nutrient management practices. | Effect of nutrient management on nutrient uptake and economics of maize (Zea Mays L.) under different tillage practices
