To explore the genetic diversity in Persian walnut (Juglans regia L.) trees in Shimla (Himachal Pradesh). 212 unevenly managed trees were screened for yield and biomass contributing characters. Maximum values of coefficients of variability were recorded for nut yield (68.42%) followed by yield efficiency (66.01%). Based on nut yield, trunk and leaf characteristics the intra-specific variability was assessed using non-hierarchical Euclidean cluster analysis. All genotypes were grouped into eight clusters showing non-parallelism between geographic and genetic diversity. Genotypes of cluster 1 and 8 were highly diverse from each other having inter-cluster distance of 28.30. The mean 2 values of trunk cross-sectional area (cm ) were higher (1262.06) and (1005.52) in genotypic clusters 1 and 5, respectively. Genotypes of cluster 3 recorded highest nut yield (27.32 kg/tree) and were selected for their further evaluation in agroforestry systems.Keywords

A nutritional survey was carried out to evaluate soil fertility status in major apple growing belts viz., Jubbal-Kotkhai, Karsog, Kalpa, Kotgarh and Naggar of Himachal Pradesh (India) situated in the core of Western Himalayas and also to study the effect of nutrient concentrations on influencing yield. Soil samples were collected from twenty five orchards for two years and concentrations of nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, copper and zinc were determined. The soil macro-nutrients N, P, K, Ca, Mg in different locations were found in the range 95.11-202.58, 8.03-68.03, 53.11-278.07, 726.12-2727.11 and 126.28- 446.10 ppm, respectively while, the micro-nutrients Fe, Zn, Cu and Mg varied from 31.27- 78.23, 0.64-4.23, 1.18-4.80 and 9.97-52.11 ppm. Multiple regressions have been calibrated for predicting apple yields at different locations and for low and high yielding (>150 kg/tree) trees, where the models were found to have a high and significant predictability value. Using the data, fertilizer adjustment equations can be developed for prescribing optimum fertilizer doses for attaining high yields in the apple production areas in the Western Himalayas and indeed elsewhere with similar c1imatic and soil conditions.Keywords

M. hexandra is indigenous to India, found wild in the forests of South India, Northcentral India, parts of Gujarat and Rajasthan. In India this species is generally cultivated near villages, backyards and homestead gardens in the parts of Madhya Pradesh, Gujarat, Rajasthan and Vidharbha region of Maharashtra and also found as natural wild populations.- Impediments and revamping possibilities in India’s agriculture extension services
