The kandi region comprising 0.5 m ha (about 9.5%) of Punjab, India, is characterized undulated topography, light soil texture, heavy run off and soil erosion losses, poor moisture retentivity and devoid of easily exploitable underground water sources, and is therefore highly dependent upon seasonal south-west monsoon (July-September). It is coupled with poor infrastructure of roads and marketing, illiteracy, heavy cattle and human population pressure and agriculture adopted as subsidiary occupation. About 25-40% of the monsoon rains is lost as run off. The soils are non-saline, organic carbon averages 0.24% in loamy sand and 0.30 or more in sandy loam soils. The corresponding values of moisture retention at 1/3 bar or field capacity range from 8.1 to 15.8% and at 15 bar (permanent wilting point) from 3.7 to 4.8% in 0-180 cm soil layer of loamy sand soil and 16.2 to 21.5% and 3.7 to 7.6% respectively in sandy loam soil. In situ soil moisture conservation with the minor leveling, bunding and installation of suitable water structure helped to increase the yield of wheat [ Triticum aestivum] + gram [ Vigna mungo] by 57% and pearl millet by 25%. In light soil, green manuring during kharif gave an edge of 0.5 q/ha over the fallow fields on account of more rain water conservation and addition of green matter in soil. Mulching in standing maize [ Zea maize] in kharif helped to conserve the moisture in seed zone (0-15 cm) layer and ensured germination of succeeding wheat crop. Using the stored water in ponds during rainy season and its use as light irrigation (5 cm) at the initial moisture stress or as life saving irrigation, resulted in the better establishment of crops and increased the yield by 669 kg/ha over the controlled un-irrigated plots. Amongst the various crops, management practices conserving the soil moisture during kharif season and taking winter season crop were found promising technologies. Raya grown as an inter-rowcrop at 2.0 to 2.5 meter interval gave 2.5 q/ha seed yield. Application of fertilizer under dry land conditions seemed to be a prerequisite. It improved the above-, and below-, ground biomass and helped extend the root system to exploit water from deeper layer of soils and enabled the crop sustain the drought better and resulted in 50-70% grain yield increases in combination with fertilizer application. Under such an approach, fertilizer schedule for wheat was established at 80-40-20; N-P 2O 5-K 2O kg/ha in medium to heavy soil; and 40-20-10; N-P 2O 5-K 2O kg/ha for wheat or wheat+gram for light soils while the fodder ( kharif) and raya required just about 50 kg. N/ha.
