The experiment was laid out in Randomized Block Design with five replications. The okra cv. P-8 was sown in June, 2017 in a plot size of 2.4 m² under eight treatment modules T1– organic module, T2-insecticidal module, T3–environmental traps, T4–jeevamrit 11%, T5 –jeevamrit 9%, T6–neemastra 11%, T7 -neemastra 9% and T8 -untreated control. The results revealed that the treatment T5–jeevamrit 9% recorded higher values for growth parameters (plant height – 95.30 cm, number of ripe fruit per plant- 11.64, ripe fruit length- 16.56 cm), yield attributing parameters (fruit yield per hectare-43.20 q/ha, number of seed per fruit-69.22 but seed yield per hectare-24.14 q/ha was higher in T6 – neemastra 11%) and seed quality characters (seedling length-22.68 cm, seedling dry weight- 28.34 mg, seed vigour index-II-2427.61 but 100 seed weight-6.67 g was higher in T6 – neemastra 11%). The per cent infestation and population per plant of insects pests and damaged fruit per plant (0.60) were least in treatment T2 -insecticidal module with highest seed germination (68.87%) and seed vigour index-I (1972.34) which was found significant followed by treatment T5 – jeevamrit 9% and T6 – neemastra 11%. The treatment T5 –jeevamrit 9% gave highest benefit: cost ratio (4.45: 1), followed by treatment T6(4.34: 1) and T2(4.20: 1). Hence, application of insecticides provided maximum protection from insect pests. However economic point of view, the jeevamrit and neemastra performed better in growth, yield and quality parameters of seed with maximum benefit cost ratio and after multilocational trails these can be applied for commercial cultivation of okra seed production in the mid hills of Himachal Pradesh.ennullThesis
