Effect of organic growth promoters on growth and yield 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 de sign with three replications. Results revealed that under foliar spray of Panchagavya @ 4 % was recorded maximum plant height (63.7 cm and 75.0 cm) and number of primary branches (8.0 and 10.0) at 60 and 90 DAS over rest of treatments but it was found at par with foliar spray of vermiwash @10 and 15%. Signifi cantly higher number of leaves (69.8 and 76.9), stem diameter (0.65 and 0.66 cm) at 60 and 90 DAS  and leaf area (10.13 cm2) at 45 DAS was recorded with foliar spray of Panchagavya @ 4 % over control. However, it was found at par with foliar spray of vermiwash @15%. The minimum days required to first flowering (51.1 days), minimum days required to 50 per cent flowering (53.8 days), node on which first flower initiated (10.85) and minimum days required to first pod harvest (69.59) over control. The maximum pod yield (4.08 kg plot-1) 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% of pea.
