Effect of fertigation, split and mulching on n, p and k contents (%) in leaf of papaya cv. taiwan 786under south gujarat conditions

An experiment was conducted on “effect of fertigation, split and mulching on N, P and K contents (%) in leaf of papaya cv. Taiwan 786 under south Gujarat conditions” with twelve treatments viz., 1st factor three levels of N and K2O @ 100, 80 and 60 % of RD (200:200:250), 2nd factor two levels of splits and 3rd factor two levels of mulching of black plastic mulch (BPM) @ 20 % area coverage (50 µ) in RBD with factorial concept (FRBD) including three replications at two locations during 2012-13. The results indicated that the nutrient status in papaya leaf were found statistically effective at the age 180 and 300 days due to N and K2O @ 100 % RDF (F1)applied with 18 splits as well as 15 days after transplanting (DAT) in both the locations showed better results as compared to control. For getting higher uptake of nutrient contents (%) in leaf of papaya, fertigation with N and K2O @ 100 % RDF and 18 splitsat 15 days intervals after transplanting of papaya cv. Taiwan 786 should be adopted.
