摘要

A field experiment was conducted during the 1999/2000 and 2000/01 rabi-summer seasons in red sandy loam soil of Main Research Station, University of Agricultural Sciences, Bangalore, Karnataka, India, to study the effect of drip fertigation on soil water, soil fertility and yield of field-grown tomato (Lycopersicon esculentum cv. Arka Abhijit) in the semiarid tropics. Fertigation with 100% water soluble fertilizers increased the marketable fruit yield and water use efficiency compared to soil application of fertilizer directly either with furrow or drip irrigation. Subsurface drip fertigation was on par with surface drip fertigation in maintaining favourable soil moisture and enhancing the yield. Fruit quality parameters were not altered either by drip irrigation or fertigation except the ascorbic acid content and titratable acidity. Drip fertigation could maintain soil fertility but there was no change in soil pH and electrical conductivity.
