It is located in the Mahabharat Range or Lesser Himalaya at an average elevation of 6,710 ft (2,045.2m). it is noted for its tea industry and the Darjeeling Himalayan Railway, a UNESCO World Heritage Site. Darjeeling hill areas are unique for environmental Eco-perception. The relief varies from 100 Mts. Above sea level to the mighty Kanchanjungha. There are different climatic zones with distinctive attributes and there are endangered animals like red panda etc along with memory orchids and medicinal plants are available in this hilly region. The soils of Darjeeling Hill area have developed depending upon the underlying geological structure. But, in general the sols have been developed by both fluvial action and lithological disintegration. The soil that have developed in the Kalimpong area are predominantly reddish in color. Occasional dark soils are found due to extensive existence of phyllitic and schists. Soil in the highlands stretching from the west to the east of the district along most of the interfluvial areas are mainly clayey loam and reddish in color. However, as per nutrient status, the soil is very poor in nutrient content in major part of hills. Further, no in depth study has been made to evaluate the nutrient status of Darjeeling District for last six (6) years from these soil samples. Data of the soil status of Darjeeling district on the basis of various parameters such as pH, ECE, Organic C, available phosphorus, available potassium, year wise from 2004 to 2010, to detect if there is any change in the trend of the soil nutrient status over those years.

The seedlings were raised in micro-pots (2×2.5 cm2 size) and transplanted in the main plot. The experiment was laid out in a completely randomized block design replicated thrice. The treatments consisted of three levels of plant spacing (25×25 cm2, 45×45 cm2, 60×60 cm2) and included 3 varieties one each from toria, rapeseed and Indian mustard group. Among different treatment combinations, variety Bhagirathi (from Indian mustard group), in combination with spacing of 60×60 cm2 (S3V3) was recorded with highest yield (1348.08 kg ha-1) followed by its rest of t...

Foliar application of Fe, Zn and B (at 50 and 100 ppm each) were applied twice, first at pre anthesis stage and second at pod development stage. Parameters such as plant height (cm), dry matter (g/m2), number of nodules per plant and number of pods per plant were observed highest with T8(RDF+50 ppm Zn+Fe+B foliar spray) treatment whereas the T1 (RDF) showed the lowest value for each parameter. T3 (RDF+100 ppm Zn foliar spray) resulted with maximum 1000 seed weight (g). T8 (RDF+50 ppm Zn+Fe+B foliar spray) was also recorded with the highest seed yield (kg/ha), stover yield (kg/ha). Both T7 (RDF+100 ppm B foliar spray) and T8 (RDF+50 ppm Zn+Fe+B foliar spray) treatments were resulted with the same value of harvest index followed by the rest of the treatments. Therefor...

The experiment was laid out in factorial randomised block design with nine treatment combination and replicated thrice. The experimental soil was initially slightly acidic, medium in available nitrogen, low in available phosphorus and low in available potassium. Integrated nutrient management practice with 75% of recommended dose of fertilizer + 5 t ha FYM + seed inoculation with Rhizobium performed as the best treatment amongst the treatment combinations in terms of higher number pod plant(113.4), higher number of seed pod(1.78), and higher seed yield (1293.7 kg ha)with better return rupee of investment(1.79). This treatment fetched 21.28% yield increment...

Traditionally rice in this zone is grown by transplanting of certain aged seedlings in to the puddled field. Transplanted rice requires a continuous supply of water throughout its growth and development period (Farooq et al., 2007). Transplanting of rice is labour intensive and sometimes it cause delayed transplanting due to crisis in availability of labour which ultimately fetches a lower productivity and poor return (Farooq et al., 2011). The rice cultivation practice in this old alluvial zone of West Bengal, is not standing in the place of exception. Sometimes delayed transplanting with the aged seedlings results lower productivity of upland rice in this zone due to uneven distribution of rainfall. Direct seeded rice culture is an alternative cost effective technology which requires less labour and water than conventional transplanted rice (Balasubramanian and Hil...

GB-1) under integrated nutrient practices. Highest number of effective tillers plant-1 (17.81), panicle length (29.56 cm) and number of filled grains panicle-1 (262.15) as well as seed yield (3051.89 kg ha-1) have been observed where direct seed rice crop received 75% of the recommended dose of fertilizers, FYM @ 5ton ha-1 and brown manuring with dhaincha. Highest number of effective tillers plant-1 (18.86), panicle length (28.89 cm) and number of filled grains panicle-1 (260.54) and seed yield (3079.92 kg ha-1) have also been observed with spraying of Vermiwash and N-P-K 19:19:19 at 35 DAS and 55 DAS respectively to the direct seeded rice crop. An increasing trend in residual fertility status has also been observed with this treatm...

The experiment was conducted at the seven villages namely Bong Busty, Charkhol, Sangsey, Bungkulung, Sakyong, Pudung, Didabling of Kalimpong district at an altitude ranged between 1210 m to 1300m . Significantly higher values of no. of primary branches (9.78); no. of siliquaplant-1 (82.12); no. of seeds siliqua-1 (35.51) as well as seed yield (1023 kg ha-1) were recorded with soil test based nutrient management practice along with soil application of sulphur (80%) @ 20kg ha-1as basal compared to the farmers’ practice. The soil application of sulphur and soil test based nutrient management practice also fetched higher return per rupee invested (1.61) compared to the other treat...
