Effect of irrigation and fertigation on cabbage with or without mulch

A field experiment was carried out in the at Assam Agricultural University, Jorhat during the year 2012–2013 to study the effect of irrigation and fertigation on cabbage with or without mulch. The experiment was conducted in randomised block design with three replications. The treatment comprised of three level of irrigation viz., 100, 75, 50 percent OPE and three level of fertigation, viz., 100, 75, 50 percent RD of N and K based on recommended dose 120: 60: 60 kg ha⁻¹. Phosphorus was applied as basal dose uniformly with or without mulch. 100% OPE, 100% RD of N and K with mulch recorded significantly the highest plant fresh weight (3.39 kg), head weight (3.03 kg), head diameter (22.00 cm), compactness (23.00) and yield (130.49 t ha⁻¹). The minimum days (29.33) for head initiation and days to maturity (55) were recorded under 50% OPE, 50% RD of N and K with mulch treatments.
