Abstract
The present investigation entitled "Studies on the Effect of Neem Botanicals on Seed Longevity of Field Pea (Pisum sativum L.) during Storage under Ambient Conditions" was undertaken to find out the efficacy of insecticides, seed germination, seedling growth and vigour. The experiment was carried out at the Department of Seed Science and Technology, C.S. Azad University of Agriculture and Technology, Kanpur during 2023-24. Seeds of field pea var. KPMR 522 were treated with T1 (Neemazal T/S @ 25 ppm), T2 (Neemazal T/S @ 50 ppm), T3 (Neemazal T/S @ 75 ppm), T4 (Neemoz-Gold @ 25 ppm), T5 (Neemoz-Gold @ 50 ppm), T6 (Neemoz-Gold @ 75 ppm), T7 (Deltamethrin @ 1.0 ppm (0.04
ml/Kg seed)) and T8 (Untreated Control). The experiment was conducted in Completely Randomized Design with three replications. Observations were recorded and analysed for germination at first count, standard germination, shoot length, root length, total seedling length, seedling dry weight, seedling vigour index-I (SVI), seedling vigour index-II (SVII), peak value, mean daily germination, germination value and relative growth index. The ANOVA showed that treatments had significant effect on the all parameters studied. Among all the treatments, Neemoz-Gold @ 75 ppm expressed significantly best performance in germination at first count (64.67%), standard germination (82.33%), seedling length (16.93 cm), seedling dry weight (1.97 g), seed vigour index-I (1439.05), seed vigour index-II (167.45), peak value (13.72), mean daily germination (10.29), germination value (141.21), relative growth index (78.50) and insect mortality per cent of pulse beetles (Callosobruchus chinensis L.) on the 3rd day (43.33%), 7th day (56.67%) and 15th day (66.67%) while minimum Seed infestation per cent (2.89%) and Seed moisture content (8.89%) at 12 months of storage followed by Deltamethrin @0.04 ml/kg.
