ABSTRACT

In scarce-irrigated areas of India, pearl millet-wheat cropping system is depleting soil quality, system productivity and resources. The objective of study was to restore soil quality and sustain productivity. It was considered necessary to diversify cereal through legume-based wheat system and shift of traditional to conservation technologies. A field experiment was assessed the rainy season cereal crop pearl millet (PM) and three legumes- pigeon pea (PP), green gram (GG) and cluster bean (CB)-based winter wheat (W) systems under two land levelling methods viz. traditional (TLL) and precision laser assisted (PLL), and three establishment methods- traditional tillage (TT), zero tillage (ZT) and permanent broad bed- furrow (PBBF) on various parameters. Results of PLL and PBBF crop establishment was significantly enhanced the soil quality parameters, growth characters, less plant mortality of rainy season crops and lodging of wheat compared with traditional practices. Overall improvement in soil quality, system- and water productivity (WP) and net returns were in ordered: PP-W > CB-W > GG-W > PM-W and PBBF > ZT > TT. Results indicated that PBBF crop establishment in PLL conditions can be made more sustainable productive, economic profitable, ameliorate soil quality and save resources in scarce/canal support irrigation system.

基于小麦的系统的精确平整和作物建立选项对稀缺灌溉地区土壤质量、系统和水生产力的影响

摘要

在印度灌溉稀缺的地区,珍珠粟 - 小麦种植系统正在消耗土壤质量、系统生产力和资源。研究的目的是恢复土壤质量和维持生产力。人们认为有必要通过以豆类为基础的小麦系统和传统技术向保护技术的转变,使谷物多样化。田间试验评估了雨季谷类作物珍珠粟 (PM) 和三种豆类 - 木豆 (PP)、绿豆 (GG) 和丛豆 (CB) 型冬小麦 (W) 系统在两种土地平整方法下的田间试验,. 传统(TLL)和精密激光辅助(PLL),以及三种建立方法 - 传统耕作(TT),零耕(ZT)和永久性宽沟(PBBF)的各种参数。与传统做法相比,PLL 和 PBBF 作物定植的结果显着提高了土壤质量参数、生长特性、减少了雨季作物的植物死亡率和小麦的倒伏。土壤质量、系统和水生产力 (WP) 以及净收益的总体改善顺序为:PP-W > CB-W > GG-W > PM-W 和 PBBF > ZT > TT。结果表明,在 PLL 条件下建立 PBBF 作物可以使生产更具可持续性、经济效益更高、改善土壤质量并节省稀缺/渠道支持灌溉系统中的资源。
