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).
