SCHEDULING OF DRIP IRRIGATION AND FERTIGATION IN RABI GARLIC (Allium sativum L.) 2564

Abstract

An experiment entitled “Scheduling of drip irrigation and fertigation in rabi garlic (Allium sativum L.)” was conducted on medium black calcareous soil at Farming System Research Centre, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh (Gujarat) during rabi seasons of 2015-16 and 2016-17. The experiment was laid out in split plot design with four replications. The main plot treatments viz.; (i) drip irrigation at 60% PE, (ii) drip irrigation at 80% PE and (iii) drip irrigation at 100% PE, sub plots consist of four fertigation schedules viz.; (i) 100% RDF as basal through fertigation, (ii) two equal splits of RDF through fertigation at 30 days interval, (iii) three equal splits of RDF through fertigation at 20 days interval, (iv) four equal splits of RDF through fertigation at 15 days interval. The garlic (cv. Gujarat Garlic-4) was grown with adopting standard package of practices. The results revealed that drip irrigation scheduling at 100% PE with four equal splits of recommended dose of fertilizer through fertigation enhanced growth parameters and yield attributes which ultimately resulted in higher bulb and straw yields of rabi garlic.
