A CASE STUDY OF NUTRITIONAL STATUS OF CHERRY (Prunus serotina), ORCHARD SOILS AND FRUIT QUALITY ATTRIBUTES OF BALTISTAN REGION

Abstract

This study had been conducted in north eastern area of Pakistan, Baltistan region constituting the larger portion of Kashmir region. Which is one of the moist zone of the western Himalayas. While growing fruit point of view the land is suitable for fruit like apples, plum, cherry and apricot production.  Climatically Baltistan region soils have recognized as best for quality cherry production. However, limited information is available about the existing soil fertility status and fruit quality of cherry orchards. Soil fertility evaluation is a key factor towards sustainable fruit production of cherry orchard soils. Improvement of soil productivity and fruit quality depends on the knowledge of the soil fertility. Therefore, study was designed to investigate the soil fertility status of cherry orchards of District Skardu, Kharmang, Shigar, and Ganache. Soil samples were evaluated for pH, EC, Organic matter, Texture, N, P, K, and micronutrients. While leaf and fruits samples were analyzed for N, P, K and pH, TSS, TA, Ascorbic acid, and Sugar contents respectively. Results revealed that the soil samples were slightly alkaline and non-saline sandy loam and sandy clay loam texture with adequate organic matter ranging from 1.19-2.15%, Low to marginal (NO3-N), low extractable P, and marginal to adequate K with high micronutrients concentrations (Cu, Zn, Fe, and Mn). While leaf samples showed marginal to high N, low P, and K and sufficient to high micronutrients. The parameters of fruit samples were in the optimum range with a yield of 5-50 Kgplant-1.
