ABSTRACT
The present study was based on the germplasm evaluation experiment, which involved the evaluation of 45 germplasms/lines including three checks viz. NDR-97, NDR2065 and Saraju-52. The experiment was conducted in Augmented Block Design with three replications. The field experiment was carried out in Kharif season 2022 at the Crop Research Station (CRS), Masodha and lab experiments were conducted in the Seed Testing Laboratory, Seed Technology Section, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.). The path coefficient analysis was worked out by using simple correlation among 13 characters to estimate the direct and indirect effect of different characters on grain yield per plant. The highest positive total effect (direct + indirect) on grain yield per plant was exhibited by panicle bearing tiller per plant (0.699) followed by germination % (0.360), seed viability (0.227) and vigour index – I (0.209). The highest number of genotypes appeared in the cluster – II (13), followed by cluster – III (8), cluster – IV(6), cluster – V(6), cluster – I(5), cluster – IX(5), cluster – VI(3), cluster – VII(1), and cluster – VIII(1). The maximum intra-cluster distance was observed in case of cluster – IX (64641.91) followed by cluster – V (5584.50), cluster – VI (5363.09), cluster – I (3918.44), cluster – II (3483.30), Cluster – IV (3303.54), Cluster – VII(0.00) and cluster – VII (0.00). The highest cluster mean for days to 50% flowering was recorded for Cluster-I (102.8) followed by Cluster – VII (99), cluster-V (96.66), cluster-VIII (96) cluster IX (96), Cluster III (95.75) cluster IV (95.65) cluster VI (94.67) cluster II (91.51).
ABSTRACT
Mungbean [Vigna radiata (L.) Wilczek] is the important source of proteins, minerals, and vitamins of the predominantly vegetarian Indian diet. It belongs to the family Leguminaceae. Web blight caused by Rhizoctonia solani (Kuhn) is one of the most important fungal diseases which come every year with different intensity and causes huge losses in mungbean yield. The present investigations were carried out in the laboratory, Department of Plant Pathology Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya to test the efficacy of different treatments viz., Neem, Garlic, Tulsi, onion, Ginger, T. asperellum, T. harzianum, Propiconazole and Hexaconazole against Rhizoctonia solani Kühn under in vitro condition. Botanicals and Fungicides were tested through Poisoned food technique and Bio-agents were tested through dual culture technique. Pathogen was isolated from diseased mungbean plant and further tested against different treatments. Radial growth and percent inhibition were recorded. Minimum radial growth and maximum percent inhibition were recorded in Propiconazole 1.45 mm, followed by Hexaconazole (3.65 mm), Garlic (10.18 mm), Ginger (11.43 mm), Neem (12.90 mm), Onion (15.42 mm), Tulsi (17.63 mm), T. asperellum (18.58 mm), T. harzianum (23.14 mm) as compared to Control (45.17 mm) at 24 hours of incubation. Similar trends were found at 36 and 48 hours intervals.
