Abstract:
An investigation entitled “Effect of salicylic acid and zinc sulphate on morpho-physiological parameters and yield of groundnut (Arachis hypogaea L.)” was carried out at farm of Agril. Botany, College of Agriculture, Nagpur, during Kharif 2021. The experiment was arranged in randomised block design and replicated thrice consisting of twelve treatments of salicylic acid (50 ppm, 100 ppm, 150 ppm) and zinc sulphate (0.50% and 1.00%) when applied individually and as a treatment combination. The foliar spray at 30 and 50 DAS showed significant increase in all the growth parameters i.e., plant height, number of secondary branches plant-1, days to 50% flowering, days to maturity, total dry weight plant-1, leaf area plant-1 and leaf area index, RGR, NAR and yield parameters such as number of the pods plant-1, pod yield plant-1 (g), plot-1 (Kg), ha-1 (q), seed yield plant-1 (g), plot-1(Kg), ha-1 (q), and Test weight (100 seed) and harvest index (%). Finally, it can be stated that spraying of plants with 150 ppm salicylic acid + 1.00% zinc sulphate and 100 ppm salicylic acid + 1.00% zinc sulphate at 30 and 50 DAS could be considered as the most suitable concentration and time to enhance the growth and yield of groundnut.
