Abstract
Majority of the farmers in Northern Dry Zone of Karnataka cultivate the crop during kharif season. The recommended in-situ moisture conservation practices for the zone include : broad furrow and ridge, compartment bunding, tied ridging, contour cultivation, set furrow cultivation, hill method of planting, paired row planting, wider row planting and sara method. These practices mainly aim at uniform distribution of moisture in the soil profile in the inter-terraced area. Ensured moisture availability for longer period of plant growth and check the possible sheet or rill erosion. These practices are also known to stretch the infiltration opportunity time and cause for increased rainfall use efficiency at the same time, these practices drain out excess rainfall safely out of the crop fields. The above listed in-situ moisture conservation practices require maintenance of bullock or mechanical power. Maintaining bullock power or mechanical power by the marginal and small farmer becomes not only uneconomical but also non-feasible. The affordable and potentially efficient cultivation technique for Pigeonpea appears to Zai method
