Rice is the major crop grown in Rajnandgaon district. The important insects and diseases which damage the rice crop are stem borer, brown plant hopper, leaf folder, cut worm, blast and BLB etc. Due to heavy infestation of insect and diseases, farmers used to spend huge amount of money for purchase of pesticides to control insects and diseases. Keeping this view in mind, the IPM module was applied among the farmers by the KVK for reducing the cost of pesticides. This study was carried out by the Krishi Vigyan Kendra, Rajnandgaon through trainings, OFTs, FLDs and Advisory services etc. during 2009-10 to 2010-11.The major components taken under IPM modules were deep summer ploughing, Seed treatment (for diseases), green manure (in situ), balance use of fertilizers, seedling ischolar_main dip/nursery treatment to control stem borer, 30 cm alley formations at every 2.5 to 3 meter distance for plant hopper and sheath blight, installation of light traps, pheromone traps, use of "T" shaped bird perches, application of neem oil, cow urine and warmi wash etc. It was revealed that the farmers reduced the cost of cultivation of rice by adopting IPM modules and more than 60 per cent farmers were adopted the above practices for insect and diseases management. Hence, the IPM module is very effective to manage insect and diseases in rice crop, other farmers also started to adopt this method in their fields. due to KVK efforts.Keywords

Twenty one genotypes of vegetable cowpea including checks were planted in Randomized Block Design at the experimental farm of Pt.K.L.S.College of Horticulture and Research Station, Rajnandgaon, during 2015-16. The data recorded on twenty one characters were subjected to analysis of variance. The analysis of variance revealed highly significant differences among the genotypes for all the characters studied except pod width. It indicates that sufficient variability exhisted among the genotype for the mentioned characters. The GCV value was higher for plant height, pod yield per plant indicated that these characters exhibited variability among the genotypes. The highest heritability was recorded for the characters plant height (60DAS), days of maturity , fruiting duration, 50 per cent flowering ,pod setting per cent per plant, 100 dry seed weight, 100-green seed weight. The genetic divergence in the present study observed among 21 genotypes of vegetable cowpea, showed low quantum of divergence and was grouped into five clusters On the basis of D2 analysis. Maximum number of genotypes (9) was accommodated in cluster - II. The average inter and intra cluster divergence (D) values had also been calculated. The intra-cluster distance varied from 0.00 to 5.04. The maximum intra cluster distance was shown by cluster I (5.04) followed by cluster V, cluster II, cluster III and cluster IV. The maximum inter cluster distance was observed in between cluster I and V (5.04). The cluster III showed maximum value for mean green pod yield (146.820g.) followed by cluster IV (146.156g). Crossing between the genotypes of maximum two clusters appeared to be most promising to combine the desirable characters.
