Response of frenchbean (Phaseolus vulgaris L.) to plant spacing, and nitrogen, phosphorous fertilization Singh R.V. Central Horticultural Experiment Station, Plandu, Tata Road, Ranchi, 834 010 Summary Response of Frenchbean cv. Arka Komal to plant spacing (40 cm × 10 cm, 40 cm × 15 cm and 40 cm × 20 cm) and graded doses of N (50, 75, 100 and 125 kg/ha) and P (25, 50 and 75 kg P2O5/ha) was studied on a sandy loam soil. The decreasing plant spacing from 40 cm × 20 cm to 40 cm × 10 cm improved the yield significantly without adversely affecting the pod quality. The highest net returns along with higher rate of net profit were also observed with the closest spacing. Application of N up to 75 or 100 kg/ha significantly improved pod size, vigour of plant and individual plant productivity. Significantly higher pod yield, net returns and rate of net profit were observed with 125 kg N/ha. Phosphorus application up to 50 kg P2O5/ha positively affected pod size while plant size remained unaffected. The yield of pod and net returns were recorded maximum with 50 kg P2O5/ha. The rate of net profit showed a negative effect of increasing P levels. Top | | | |
