Influence of Organic Growth Promoters on Yield and Quality of Pea (Pisum sativum L.)

Abstract

An experiment was conducted at Vegetable Farm, Department of Vegetable Science, College of Horticulture and Forestry, Jhalawar (Rajasthan) during rabi season of 2021-2022 pea.The experiment consisted thirteen treatments of organic growth promoters viz. Panchagavya @ 2%, Panchagavya @ 4%,Panchagavya @ 6%, Jeevamrut @ 2%,Jeevamrut @ 4%, Jeevamrut @ 6% and Brahmastra @ 2%, Brahmastra @ 4%, Brahmastra @ 6% and vermiwash @ 5%, vermiwash @10%, vermiwash @15% and Control) and laid out in randomized block design with three replications. Results revealed that the foliar spray of Panchagavya @ 4% was recorded higher chlorophyll content (2.81 mg/100g) in leaves over different growth promotors and control but it was found at par with the application of Panchagavya @ 4% , Vermiwash @ 5%,Vermiwash @ 10%, Vermiwash @ 15%,Jeevamrut @ 4%and Brahmastra @ 6% in pea. Significantly higher crude protein content (24.97%),ascorbic acid content (27.52 mg/100 g) and TSS content 19.0 ˚Brix were recorded with foliar application of Vermiwash @ 10% over control, Vermiwash @ 5%, Jeevamrut@2%, Jeevamrut @ 4%, Brahmastra @ 2%, Brahmastra @ 4% in pea. However, it was found at par with application of Panchagavya@ 2%, Panchagavya@ 4%, Panchagavya@ 6%, Vermiwash@ 10%, Vermiwash @ 15%, Jeevamrut @ 6% and Brahmastra @ 6% in the pea. Results revealed that under foliar spray of Vermiwash @ 15% (157.34 q/ha) and lowest was found in under control (118.76 q/ha), but it was found at par with application of Panchagavya@ 4%, Panchagavya @ 6%, Vermiwash @ 10%, Jeevamrut @ 4%, Jeevamrut @ 6%, Brahmastra @ 4% and Brahmastra @ 4% yield of pea.
