Effect of fertigation and foliar application of nutrients on growth and yield of French bean (Phaseolus vulgaris L.)

Abstract

A field experiment was conducted to evaluate the effect of fertigation and foliar application of nutrients on growth and yield of French bean (Phaseolus vulgaris L.). The experiment consisted of four main plots i.e., different levels of fertigation and three sub plots i.e., foliar spray of different nutrient solutions. The experiment was conducted in split plot design and it was replicated thrice. 100 per cent RDF through fertigation and foliar application of 0.5 per cent vegetable special recorded higher plant height (53.20 cm), maximum number of branches (5.70), higher leaf area (5.70 cm2) and chlorophyll content (53.58 SPAD values). Maximum number of pods per clusters (7.87), more number of clusters per plant (6.73), yield per plant (171.73 g) and yield per hectare (8.22 t) were also higher in the same treatment. Higher nitrogen uptake (67.69kg ha-1), phosphorus uptake (11.24 kg ha-1) and potassium uptake (90.90 kg ha-1) was observed in 100 per cent RDF through fertigation and foliar application of 0.5 per cent vegetable special compared to other treatments. It was observed that 100 per cent RDF through fertigation and foliar application of 0.5 per cent vegetable special enhanced the growth, yield and nutrient uptake in French bean.
