Abstract:

A study was undertaken at Zonal Agricultural Research Station, V.C. Farm, Mandya which comes under Southern Dry zone of Karnataka during Kharif-2015 and Kharif-2016 to investigate the effect of drip fertigation on nutrient uptake andyield of drip irrigated hybrid maize (Zea mays L.). The experiment was laid out in a Randomized Complete Block Design using factorial concept involving different fertigation intervals and duration with varied levels of fertilizers and replicated thrice. The results revealed that application of 125 percent of recommended nitrogen and potassium through drip fertigation with four or eight days interval with fertigation duration of 25% at 0-30DAS+50% at 31-50DAS+ 25% at 51-80 DAS resulted in higher kernel yield (86.85q ha-1) and stover yield (103.73 q ha-1). Whereas, drip fertigation of 75% of recommended nitrogen and potassium with the same fertigation duration was found on par with 100% recommended NPK application under surface irrigation method (69.34, 79.80q ha-1and 68.81, 79, 20 q ha-1, respectively). The higher net returns and B: C was found in drip fertigation treatments with the above combinations when compared to control where surface irrigation method was followed.
