Abstract:
A field study was investigated in 2016-17 at G.B. Pant University of Agriculture and Technology, Pantnagar, to study the effect of drip irrigation on nutrient uptake and nutrient use efficiency of wheat (Triticum aestivum). The experiment was carried out in RBD with eight treatments and four replications. Results revealed that the uptakes of nutrients (NPK) were significantly higher recorded in T5 (N- 130.86 kg ha−1, P- 31.47 kg ha−1 and K- 144.50 kg ha−1) and lower in T2 treatment (N- 96.13 kg ha−1, P- 19.68 kg ha−1 and K- 109.46 kg ha−1). Result further revealed that use efficiency of nutrients was higher in the treatments of T5 (23.30) and T4 (22.18) where water supply with 100 and 75% CPE respectively through drip irrigation at two days interval. Maximum nitrogen use efficiency was observed in T5 (19.58, 0.51 and 37.85) in terms of AEN, REN and PEN. Highest grain yield was found in T5 (5825 kg ha−1). In terms of economy highest B: C ratio was obtained with treatment T5 (3.57).Compare to farmer practice (T2) all the drip irrigated treatments results significant benefit in terms of nutrient use efficiency and economy.
