dc.description.abstractABSTRACT The present investigation entitled “Studies on the effect of biopesticides against major pests affecting fruit and seed yield in tomato (Solanum lycopersicum L.) were carried out using cv. Solan Lalima”. The experiment was laid out in Randomized Complete Block Design (Factorial) in the field and in Completely Randomized Design in Laboratory at department of Seed Science and Technology, Dr. YS. Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2018-19. There were eleven biopesticides modules, M1-Trichoderma viride @ 50g/plot + FYM @ 10 kg/plot + Neem oil @ 3 ml/l, M2Trichoderma viride @ 50g/plot + FYM @ 10 kg/plot + Bacillus thuringiensis @ 2g/l, M3- Trichoderma viride @ 50g/plot + FYM @ 10 kg/plot + HaNPV (250LE) @ 1ml/l, M4- Trichoderma viride @ 50g/plot + FYM @ 10 kg/plot + Neem oil @ 5ml/l, M5- Trichoderma viride @ 50g/plot + FYM @ 10 kg/plot + Cow Urine @ 50ml/l, M6- Neem Cake @100 g/plot + FYM @ 10 kg/plot+ Neem oil @ 3 ml/l, M7- Neem Cake @ 100g/plot + FYM @ 10 kg/plot + Bacillus thuringiensis @ 2g/l, M8- Neem Cake @ 100g/plot + FYM @ 10 kg/plot + HaNPV (250 LE) @ 1ml/l, M9- Neem Cake @ 100g/plot + FYM @ 10 kg/plot + Neem oil @ 5ml/l, M10- Neem Cake @ 100g/plot+ FYM @ 10 kg/plot + Cow urine @ 50ml/l, M11- Control. The result showed that the module M4 recorded higher values for growth & yield parameters. No. of fruits per plant (29.13), healthy fruits per plant (22.80), least disease infected fruits (9.62%), fruit weight (79.43g), fruit yield (1.81 kg/plant) (21.73 kg/plot) and (536.57 q/ha), No. of seeds per fruit (95.00) seed yield (6.22 g/plant) (74.61 g/plot) and (184.22 kg/ha) and seed quality characters (Germination percentage (91.75), seedling length (20.30 cm), seedling dry weight (1.78 mg), 1000 seed weight (2.92g), SVI-I (1861.83), SVI-II (163.36) and highest benefit: cost ratio (6.45:1) were also recorded in the M4 module. While the least population of leaf miner (2.51) and aphids (12.03) per plant were in module M9 and minimum fruit borer population per plant (1.00) and least insect infested fruit (6.54 %) were in module M8. From the present investigation it can be concluded that the module M4 -Trichoderma viride @ 50g/plot + FYM @ 10 kg/plot + Neem oil @ 5ml/l was found most superior for plant growth parameters and protection from insect pests which resulted higher yield of quality seeds and can be recommended for commercial seed production of tomato.en_US
