EFFECT OF DRIP IRRIGATION ON YIELD AND WATER USE EFFICIENCY ON BRINJAL (SOLANUM MELONGENA) CV. PANT SAMRAT

Drip irrigation is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone through a network of valves, pipes, tubing and emitters. It is done through narrow tubes that deliver water directly to the base of the plant. Though, India has the largest irrigation network, the irrigation efficiency does not exceed 40%.The average rainfall in Uttar Pradesh is 650 mm as against the average rainfall of 1200 mm in the country. Due to water scarcity, the available water resources should be very effectively utilized through water saving irrigation technologies. Diversification of cropping pattern particularly in favour of vegetable crops is becoming popular among farmers because vegetables are most important component in a balanced diet. But diversification of area from field crops to olericulture to meet the demand is not desirable. The maximum yield of crop 900 gm/plant and minimum of yield 600 gm/plant and total yield 52270 gm (52.270 kg).The increase in water use efficiency for drip irrigation system. Among the drip irrigation levels, the highest field water use efficiency (6148.31kg ha-1 cm-1) was found at 65% irrigation level, indicating comparatively more efficient use of irrigation water with a possibility of water saving of 35% water by adopting brinjal plot (1.58 litre plant-1day-1)
