KANWAR SINGH, J.N. RAINA and ASHOK KUMAR NANGLIYA. 2016. Nutritional status of apple orchards in district Shimla of Himachal Pradesh. Green Farming Vol. 7 (3) : 654-658 ; May-June, 2016

ABSTRACT
The investigations were undertaken to determine the nutritional status of apple orchards, located in different blocks of district Shimla and to establish the relationships among soil characteristics and nutrient content of soils and plants. Based on uniformity in respect of age and growth a total of 50 apple orchards were selected in ten blocks (Rampur, Chopal, Narkanda-I, Narkanda-II, Theog, Jubbal-Kotkhai, Rohru-I, Rohru-II, Nankhari, and Mashobra ) of the district. Soil (0-20 and 20-40 cm depths) and plant (leaf) samples collected from apple orchards (cv. Royal Delicious) were analyzed for some of the physico-chemical properties and for their macro-nutrient (N, P, K, S) status. Soil reaction (pH) was found to be slightly acidic to near neutral and electrical conductivity values were in safe limits (0.8 dSm-1). Almost all the samples registered high organic carbon content. However, soils were low to medium in available N and high in P and K status, whereas S was in sufficient range. Leaf analysis revealed low to sufficient levels of N, P, and K. Whereas S ( in 2% orchards) was found deficient. A significantly negative correlation of pH with available P was observed. Electrical conductivity was significantly and positively correlated with available N, P and S in surface and with N and Kin sub-surface soils. Organic carbon was positively and significantly correlated with all the analyzed nutrients both in the surface and as well as subsurface soils. Clay content also exhibited an almost similar relationship with the available nutrients. Organic carbon and clay content were also positively and significantly related with leaf nutrients. Surface as well as sub-surface soils exhibited positive and significant relationship with all the analyzed leaf nutrients except P which was non-significant for surface, and P and K for sub-surface soils. It is expected that the present results will be helpful to the growers, planners and other user agencies for effective and judicious application of fertilizers in order to have higher yields of quality fruits.
