Abstract

Agriculture is a backbone of Indian economy India has facing number of problems which include increasing in population, depletion of water availability, runoff and cultivated land. India only 34% of the water resources is an available to meet the increasing demands of agriculture, industry and urban usage. The quality and availability of water are two major factor that affects irrigation in crops. Adequate is essential for good germination of all crops. Irrigated lands now produce 4% of the food supply which doesn’t meet the required supply to avoid all the above problems, a new sustainable land and water management technique is introduced which is called Zai pit method. Zai pit technology provides a window of opportunity for farmers to improve crop performance in harsh & changing climate. This method increases the amount of water stored in the soil profile by trapping rain water. The methodology followsZai pit technology resulted in high tomato yield of (4081.63 kg/ ha) compared to furrow irrigation of (2040.81 kg/ha) respectively. Plant growth in zai pit technology is observed more uniform compared with furrow irrigation. Field water use efficiency of zai pit technology (13.84 kg/ha-mm) is 4 times more when compared with furrow irrigation (3.05 kg/ha-mm).
