Effect of foliar application of varying doses of salicylic acid at different growth stages on growth, quality and nutrient uptake efficiency of French bean (Phaseolus vulgaris L.)

Background: The ubiquitous presence of salicylic (SA) acid in plant systems has been confirmed by many scientists. Salicylic is widely distributed throughout the and proposed to affect a number phyto-physiological activities. As an endogenous growth factor or hormone SA functions including florigenic thermogenic role, part plant-pathogen interaction, signal transduction, etc. Method: present investigation was conducted at Experimental Farm Division Vegetable Science, SKUAST-K, during Kharif 2020 find out effect foliar spray varying doses applied different stages on quality attributes French bean var. Shalimar Bean-1. experiment laid split plot design with twelve treatment combinations three replications. Result: revealed that combination T1D2 (250ppm emergence stage) recorded minimum values for days taken 50 per cent flowering pod formation. Moreover, same also maximum height, primary branches plant-1, leaves plant-1 et al., leaf area shoot dry weight plant-1. It further vitamin C content, TSS, protein chlorophyll content matter were recorded, while anthocyanin T2D2 vegetative stage). significantly enhanced nutrient uptake efficiency plants resulted lowest available nitrogen, phosphorus potassium, soil EC organic carbon as compared absolute control. than control D0.
