“…In the study by Basso et al (1990) nutrients in soil and leaves or fruits were rare and inconsistent throughout the experimental years. The poor correlation between soil and plant (leaf or fruit) nutrients might be a consequence of good soil fertility.…”

Soil, leaf and fruit samples were collected from nine apple orchards in the Åland Islands during 1993-95. Early, intermediate and late apple cultivars were studied. Leaves were sampled three times during fruit development. In the experimental orchards, mean soil pH was 7.0 and the concentrations of extractable nutrients (mg l -1 soil) were: P 30; K 216; Ca 6000; Mg 180. The mean values of nutrients in the leaves (% DM) were: N 2.2; P 0.22; K 1.7; Ca 1.7; Mg 0.22, and in the fruit (mg 100 g -1 FW): N 47; P 10; K 125; Ca 5; Mg 5. During the sampling period (22 July-26 August), N, P and K in the leaves decreased and Ca increased. Nutrient levels in the leaves were satisfactory, but N, P and K concentrations in the fruit were low. There were significant linear correlations between the corresponding fruit and leaf nutrients, positive for N, P, K and Mg and negative for Ca. Leaf Mg and fruit K correlated significantly with the corresponding soil nutrients. P and Ca in leaves and fruits correlated with soil pH more closely than with the corresponding soil nutrients.

“…Soil and leaf analysis of the samples from the region revealed deficiency with regard to important macro and micro elements which could be attributed to low agricultural activities caried out in the region with short growing seasons coupled with harsh climatic conditions and small agricultural land holdings. Soil analysis is important to evaluate nutritional status of soil and leaf analysis is equally important for redressal of disorders, if any (Basso et al, 1990) [12] . Present finding regarding pH of soil indicated alkaline nature of soil in the region which could be attributed to leaching of basis and variation in organic matter as reported by Minhas and Bora (1982) [13] and Dar et al, (2020) [3] .…”

Sericulture has great potential to alleviate poverty and unemployment in the areas where sericulture has not been introduced. High altitude belts of the J & K, like Kargil where scope of other agricultural crops is limited due to short growing seasons, sericulture has the scope to be introduced for long term basis to ensure the livelihood security and better socio-economic status of the people from this tribal region. To see how economic activities in Kargil district can be given right focus, a study on silkworm rearing cum demonstration program was launched by CoTS, SKUAST-K, Mirgund at high altitude Kargil-Ladakh during July-August 2018 and 19. In order to assess the feasibility and sustainability of sericulture in the region, a popular bivoltine silkworm double hybrid (FC2 x FC1) was procured from Nodal Silkworm Seed Agency, NSSO, CSB, GoI, Bangalore which was reared for two consecutive years in three different border villages of Kargil viz, Akchamal, Mangbour and Shilikchey. Although prior to this, small scale silkworm rearing trails were conducted at Kargil during 2012-13, 2015-17 and 2018-19 by CoTS, SKUAST-K, Mirgund and CSRTI, CSB, Pampore respectively and have reported encouraging results which laid the basis of this study for further expansion and strengthening of sericulture activities in new far flung border areas of Kargil.. As such, the present investigation was aimed to test the validity of the results obtained in previous study trails for commercialization and popularization of sericulture in the region. The results obtained in the current investigation were encouraging and revealed highest hatching percentage of 98.70 and 97.80 during the year 2018 and 2019 respectively. Average Cocoon yield of 48.20 and 47.40 Kg/100 DFLs' was obtained during 2018 and 19 respectively. Average Single Cocoon Weight (SCW) and average Single Shell Weight (SSW) of 1.78g and 0.38g was obtained during 2018. whereas in 2019 it was 1.76g and 0.39g respectively. Average Shell Ratio (SR%) of 21.34% and 22.15% was also obtained during the year 2018 and 19 respectively. Hence, results of the present investigation attest the validity of the previous study trails conducted in the region from time to time and established that sericulture can be promoted at high altitude Kargil region of Ladakh on sustainable basis, the prospectus of which are underlined in the study.
