Abstract

Building resilience to climate change through on farm management techniques such as crop diversification, and water management as supplemental irrigation is vital for sustainable agriculture. In the present study, soybean (Glycine Max L.) based cropping systems (sole crop, and intercropped with cotton or pigeon pea) through different combinations of cultivation practices (flatbed, raised bed) and irrigation levels (Rainfed, 66%ETc, 100%ETc and methods (drip, sprinkler) were studied in randomized block design with three replications during kharif season of 2019-20 and 2020-21. Plant growth parameters viz. plant height and dry weight were recorded maximum in rainfed soybean as sole crop, while the number of branches/plant were recorded maximum in sole soybean crop irrigated at 100%ETc. Grain yield (5.37 t ha-1), and water productivity (0.47 kg m-3) were maximum in soybean intercropped with cotton. Overall, cotton+soybean irrigated at 66% ETc can be adopted by farmers to achieve optimal productivity without significant yield penalty.

中央邦不同气候条件下大豆种植系统的技术经济可行性

通过作物多样化等农场管理技术以及作为补充灌溉的水资源管理来增强对气候变化的抵御能力，对可持续农业至关重要。本研究采用随机区组设计，在2019- 2020年和2020-21年收获季，采用3个重复试验，研究了大豆(Glycine Max L.)为基础的种植制度(单作、间作棉花或木豆)，通过不同的栽培方式(平耕、垄作)和灌溉水平(旱作、66%等、100%等)以及方法(滴灌、喷灌)的组合。单茬旱作大豆植株生长参数(株高和干重)最高，单茬大豆单株枝数最高。大豆间作棉花籽粒产量最高(5.37 t hm -1)，水分生产力最高(0.47 kg m-3)。综上所述，农民可以采用66% ETc灌溉棉花+大豆，在不造成显著减产的情况下实现最优生产力。
