Medium quantum of genetic divergence was observed among sixteen apple genotypes under the present study. All the genotypes, on the basis of total variability were grouped into four distinct clusters. Maximum number of cultivars were accommodated in cluster IV (Fuji, Gala, Jonadel, Jonagold, Red Fuji, Royal Gala and Spijon) followed by cluster I (Arlet, Ruspippin, Sinta and Summerred), Cluster III (Crimson Gold, Elstar and Neomi) and cluster II ('Spartan' and 'Quinte'). Cluster IV had highest intra cluster value (9.32) so was most divergent and cluster I having least intra cluster value (8.20) was least divergent. Highest value (30.331) for inter cluster distance was recorded between cluster I and II while it was lowest (9.994) between cluster III and IV. Cluster means were maximum in cluster II followed by cluster I, cluster III and cluster IV. Neomi was best cultivars for fruit yield/plant, fruit length, fruit diameter, fruit weight, total sugars and non-reducing sugars, however, Jonagold was best for TSS. Cultivars Spartan, Elstar, Royal Gala, Jonagold and Summerred would prove best for different vegetative characters.Keywords

Among the several factors attributed to low productivity of potato, damage of crop due to late blight is substantially important. Prevailing farmers practices, control/check i.e. no spray along with recommended practice i.e. (Mancozeb @ 0.25% followed by application of Metalaxyl + Mancozeb @ 0.25%) were treated for comparision to control the blight disease. The results of the On Farm Trial brought out that the recommended practice of using Mancozeb @ 0.25% followed by application of Metalaxyl + Mancozeb @ 0.25% to manage late blight of potato was feasible and economically viable over farmers practice. Yield performance of recommended practice was 220q/ha which was almost 46.7% over control/check and 26.7% higher than farmers practice i.e. Mancozeb @ 0.25% which was 190q/ha. Cost benefit ratio of recommended practice (2.52) was higher over farmer's practice (2.36) and control/check (1.98). Participatory approach involving extension works and farmers in demonstration of research emanated proven technology may go a long way to curtail losses due to pest /disease incidences.Keywords

Pooled analysis of two-year data on nutrient status of 'Sardar' guava raised under organic manures and biofertilizers indicated that maximum leaf nitrogen (1.73%), phosphorus (0.24%), potassium (1.23%), calcium (1.96%), magnesium (0.80%); and maximum fruit nitrogen (1.12%), phosphorus (0.15%), potassium (0.94%), calcium (0.22%), magnesium (0.66%) was recorded, respectively, after fruit harvest with application of full dose of nitrogen to the plant applied through poultry manure augmented with Azotobacter and Azospirillium.Keywords
