Response of Groundnut (Arachis hypogaea) to the Exogenous Application of Growth Hormones (IAA, IBA, Kin, GA3, 2-4 D and BAP)

Kashyap Patel, Nimisha Patel

Abstract: Groundnut (Arachis hypogea L.) or peanut is an oil, food and fodder crop which plays an important role in the agricultural economies of countries of the semi-arid tropics. Groundnut (Arachis hypogea L.) or peanut is an oil, food and fodder crop which plays an important role in the agricultural economies of countries of the semi-arid tropics. Groundnut (Arachis hypogea L.) or peanut is an oil, food and fodder crop which plays an important role in the agricultural economies of countries of the semi-arid tropics. Experiments were carried out to study the effect of growth hormones on groundnuts (G-24, KRANTI, G-20). In this study, the effect of growth regulators was studied on morphological as well as yield parameters of groundnut plants. The sowing of seed was carried out in 21 plots of 1m x 3m, Groundnut (G-24, KRANTI, G-20) seeds were sown in these plots. Groundnut (G-24, KRANTI, G-20) seeds were soaked in different hormones for 24 hours one day before sowing date. Physical parameters of each groundnut plant were checked on 30th day and 45th day after sowing date. Compared to IAA, GA3 hormone was found more effective to increase the height of the plant, the number of root nodules, the size of the seeds, number of pods, weight of seeds as well as the yield of groundnut. IAA has affected all the parameters, but except the height of the plant and length of the root, all the parameters showed non-significant change. Exogenous application of GA3 enhanced the number of root nodules and number of pods per plant, but it was found reduced due to the application of IAA. Thus, application of GA3 can be suggested for higher yield of groundnut.
