Effect of presoaking various growth regulators on the yield and biochemical characteristics of cowpea plants (Vigna sinensis L.)

Abstract

ObjectivesCowpea (Vigna sinensis L.) is one of the world's most popular and widely consumed vegetable crops, and its economic success in Saudi Arabia is dependent on high-quality yield. Cowpea is the most important indigenous legume crop in terms of economic value. Cowpea seed has been employed as both a nutritious cow feed and a human nutritional component. Cowpea seed has more amino acids, tryptophan, and lysine than other cereal grains, but fewer methionine and cystine than animal proteins. The purpose of this study was to look at the role of growth bioregulators in cowpea plant yield and yield characteristics, as well as complete protein and soluble sugar levels in seed production. MethodsThis study used plant and growth condition analysis, yield and yield component analysis, total soluble sugars and proteins in yielding seeds computation, and endogenous hormone determination. ResultsIn this work, three growth regulators were utilized to increase the physiological activity and production of cowpea plants. When compared to untreated control plants, seed presoaking in various concentrations of IAA, GA3, and kinetin appeared to improve various yield parameters such as 100-seed weight and relative growth yield, pod weight, pod length number, and total amount of seeds/pots of cowpea plants. ConclusionThis study concludes that IAA, GA3, and kinetin appeared to improve different yield parameters in cowpea plants.
