Abstract
The present investigation was conducted at Agronomy Research Farm, CSAUAT, during rabi 2021-22 and 2022-23. The experiment was laid out into Split plot design with three replicates. The parameters were observed plant viz. nitrogen content in grain and straw (%), nitrogen uptake in grain and straw (kg ha-1), phosphorus content in grain and straw (%), phosphorus uptake in grain and straw (kg ha-1), potassium content in grain and straw (%), nitrogen uptake in grain and straw (kg ha-1). Basis on the pooled data the results of study revealed that in case of tillage practices maximum nitrogen content in grain and straw (1.80 and 0.53%), Nitrogen uptake in grain and straw (93.34 and 36.26 kg ha-1). Phosphorus content in grain and straw (0.31 and 0.20%) Phosphorus uptake in grain and straw (16.23 and 13.80 kg ha-1), Potassium content in grain and straw (0.42 and 1.38%), Potassium uptake in grain and straw (22.15 and 93.88 kg ha-1) respectively was reported in conventional tillage whereas in case of various fertility levels maximum nitrogen content in grain and straw (1.83 and 0.59%), Nitrogen uptake in grain and straw (100.31 and 35.06 kg ha-1). Phosphorus content in grain and straw (0.35 and 0.25%) Phosphorus uptake in grain and straw (18.16 and 16.63 kg ha-1) respectively, Potassium content in grain and straw (0.45 and 1.41%), Potassium uptake in grain and straw (24.97 and 101.03 kg ha-1) respectively with the application of 125% RDF+ tebunconzole.
