Abstract:
A field experiment was conducted during the winter (rabi) season of 2019-20 and 2020-21 at Dhab research farm, Rajendra Prasad Central Agricultural University, Pusa, Bihar, India, to study the effect of weather parameters on dry matter production of chickpea under different tillage and irrigation practices. The treatment consisted of two tillage practices, including conventional and conservation tillage, and two irrigation methods, viz., flood and sprinkler irrigation. The treatments were allocated in a split-plot design with three replications. The results indicated that concerning tillage practices, conventional tillage produced significantly higher dry matter production at all stages over zero tillage. In the case of irrigation methods, sprinkler irrigation was the most effective, producing significantly higher dry matter production during both years. Correlation and regression studies weather parameters and dry matter production resulted that all weather parameters positively influenced dry matter production, except for the relative humidity. However, total evaporation was the most significant factor influencing dry matter production more than other weather parameters.
