Abstract:
A field experiment was conducted to evaluate the effect of mulching and fertigation on growth, yield and quality of french bean (Phaseolus vulgaris L.).The experiment consisted of four main plots i.e., different levels of fertigation and three sub plotsi. e., mulching with paddy straw, mulching with plastic polythene and no mulch. The experiment was conducted in split plot design and it was replicated thrice. Mulching with polythene and 100 per cent RDF through fertigation recorded maximum plant height (51.55 cm), number of primary branches (6.64), Leaf area (564.54 cm²), leaf area index (1.06), number of pods per cluster (10.02), number of clusters per plant (7.41), yield per plant (80.94g), yield per hectare (11.58 t ha^-1), nitrogen uptake (92.30 kg ha^-1), phosphorous uptake (9.25 kg ha^-1), potassium uptake (80.91 kg ha^-1),nitrogen use efficiency (178.35 kg pods per kg of nitrogen), phosphorous use efficiency (106.30 kg pods per kg of phosphorous), potassium use efficiency (144.12 kg pods per kg of potassium), and water use efficiency (504.02 kg ha^-1 cm^-1). Higher shelf life (8.05%), higher moisture content (89.05%),higher firmness (4.05 kg/cm²) and higher crude fibre content(16.19%)in the pods were recorded where mulching was applied along with 100 per cent RDF through fertigation compared to other treatments.
