Effect of Orgo-nutri Priming on the Germination and Seedling Traits of Groundnut (Arachis hypogaea L.)

Abstract

Background: The goal of the current study was to ascertain how well oil cake extracts functioned as nutrient source and seed priming agent for groundnut seeds in order to improve their seed quality attributes. Experiments were conducted on cv. CO 7 variety of groundnut to determine the best oil cake extracts and concentrations for seed priming. Methods: For the experiment, seed priming agents were groundnut, sesame, coconut, cotton and neem extracts from oil cakes. The various concentrations of each oil cake extract, namely 5, 10, 15 and 20%, were made and used to treat seeds with oil cake extracts at their ideal concentration. Result: The seeds pre-treated with oil cake extracts had improved seed quality, including faster germination, higher germination rates, the longest root and shoot lengths, the highest levels of dry matter production and a higher vigour index. The most effective groundnut seed priming agent was found to be 20% groundnut oil cake extract. Hence, the groundnut oil cake produced as a farm byproduct can be successfully used to increase the vigour of the seedlings, simplifying the recycling of agricultural products.
