Abstract:
Field experiments were conducted during rabi season of 2018-19 and 2019-20 at ANGRAU, Regional Agricultural Research Station, Nandyal, on vertisols with an objective to understand the impact of crop residues, time of sowing and irrigation on nutrient up take and yield of chickpea. The results indicated that, Chickpea crop grown under foxtail millet crop residue incorporated treatments recorded significantly more nitrogen, phosphorous and potassium removal through seed, haulm and total during rabi 2018 and rabi 2019, The nutrient uptake patterns showed that the first fortnight of November sown plants recorded greater nutrient uptake compared to the early (D₁) and late sown (D₄) chickpea. Similarly, increased uptake of N P and K nutrients at harvest was recorded in irrigation twice, each at pre flowering and pod development stage, followed by single irrigation at pod development stage and single irrigation at branching stage. Seed yield was higher with November 1^st FN sowing with two irrigations at pre-flowering and pod development stage. however higher harvest index was recorded with November 2^nd FN sowing.
