Rainfed horticulture system

In Yagantipalli village of Banaganapalli mandal in an area of 10 acres, farmers used to irrigate the entire orchard by basin method of irrigation with field channels, which took 12 days to irrigate entire orchard. Drip irrigation was installed with double lateral having four drippers of eight lit/hour discharge on each side of the tree. After installation of drip irrigation, each mango tree received 300 liters of water every day, which is more than the peak requirement of mango tree (peak water requirement of mango tree 150 lit /day). The data clearly indicated that with drip irrigation gave higher fruit yield (12542 Kg/ha),which was 50% more than that of farmers practice (Table 1). The improved technologies resulted in increased income and higher cost benefit ratio.

In village Amba, Ratlam district farmers face problem of low water availability during rabi season. Demonstration of rabi onion crop (var: ALR) was taken up with drip irrigation system in 1.2 ha area involving three farmers. The intervention saved 60% of irrigation water. Drip irrigation system field showed higher moisture content, better aeration, good bulb size and ultimately good quality output. The yield obtained by drip was 375 q/ha as compared to farmers’ practice 307q/ha (Table 2). The cost benefit ratio of onion crop grown in drip irrigation system was 3.13 as compared to 2.80 by flood irrigation.

Drip irrigation in mango at Kurnool, Andhra Pradesh

Cultivation of onion with drip irrigation method

in Ratlam, MP

 

Demonstrations on integrated nutrient management in mango were conducted in 12 farmer’s field in the village, Chittecherla, Chittoor. Two sprays were taken up, first one before flowering during September-October and the second at fruit set stage during Feb-March. The results showed that fruit yield improved by 18% with foliar spray of micronutrient mixture compared to farmers’ practice. There was also significant increase in fruit quality parameters, viz., fruit size and fruit weight by 17.2% and 19% respectively compared to those in farmers’ plot.

 

In NICRA village Kattusiviri, Villupuram, demonstration of drip irrigation for efficient utilization of water and fertilizer in jasmine crop was taken up. The farmer could cultivate an additional area of 0.5 acre with the available water reserves and obtained an additional income of Rs. 13,000 per acre. Adoption of drip irrigation in jasmine crop led to efficient use of water than flood irrigation. In addition, the weed population reduced considerably to a level of 40%.
