Abstract
A field experiment was conducted at Vegetable Farm, Department of Vegetable Science, College of Horticulture and Forestry, Jhalawar (Rajasthan) during rabi season 2021-2022 on 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 maximum pod yield (169.93 q/ha) of pea was recorded with foliar spray of Panchagavya @ 4 % over control. However, it was found at par with foliar spray of vermiwash @ 10% and vermiwash @15% on pea. The foliar spray of growth promotors did not significantly influence soil physio-chemical properties i.e. soil pH, electrical conductivity and organic carbon after harvest of the crop. The maximum available nitrogen (341.0 kg/ha) was recorded under application of Panchagavya @ 4% and minimum available nitrogen (337.2 kg/ha) in control. Available phosphorus (kg/ha) and potassium did not significantly influence by different growth promotors in the soil after harvest of the crop.
