保护农业（CA）可以是减轻土壤质量降低，降低径流和土壤侵蚀的可能技术，并增加原位土壤水分保护，从而提高作物产量。本研究的目的是测试和验证可持续小麦生产的有益CA实践，并加强小规模农民知道如何和技巧。在2013 - 2016年期间进行了三项CA技术验证试验。第一次试验将CA与常规农业（CVA）在2013 - 2016年“梅赫”或大雨季的南纳IP站点的农民领域。在CA核实中，土壤干扰仅限于绝对最小值;viz。在播种时，土壤才被扰乱地将种子放在土壤中。相比之下，在CVA中，在播种之前，在播种之前，土壤与当地的牛犁'Maresha'犁过四次。获得合适的苗床。通过在种植之前以3L /公顷的速率施加圆形来完成Ca中的杂草控制，而在0.5L / ha的帕拉斯45od，2,4-d以1升/公顷，则用作出苗后施用。推荐的杂草控制实践用于常规农业viz。 twice hand weeding at tillering and booting stages. During ‘belg’ (small rainy season faba bean was used as cover or break crop in early 2014 and 2015. The second CA verification trial was initiated with the introduction of zero tillage planter at Kulumsa Research Center involving zero tillage CA, minimum or reduced tillage CA and CVA in 2016. The third trial was conducted in low rainfall areas in which CA, CA coupled with tie ridge and CVA were compared at Dhera in 2014. Results of the first trial indicated that at the initial year CVA gave more wheat yield than CA. The benefits of CA has increased progressively over years and on average CA yielded 12.5% more wheat yield than CVA. Similarly, zero tillage CA increased wheat grain yield by 7.1% and 11.6% as compared with conventional and reduced tillage, respectively. In arid and semi-arid areas, CA coupled with tieridge significantly increased wheat grain yield as compared to conventional agriculture. Thus, CA could be more applicable to moisture stress /erratic rainfall areas as compared to high rainfall areas and wheat farmers in drought prone regions could possibly adopt CA technology
