Effect of Integrated Nutrient Management on Mango (Mangifera indica L.) cv. Himsagar
A field experiment was carried out for two years (2012-13 and 2013-14) to study the effect of integrated nutrient management comprising of biofertilizers (Azospirillum, Azotobacter, Trichoderma and Pseudomonas) conjointly with chemical fertilizers and organic manures on growth, yield and quality as well as soil chemical properties of mango cv. Himsagar at Bidhan Chandra Krishi Viswavidyalaya, Regional Research Station, Gayeshpur. Result revealed that treatment with half (1000:500:1000 g NPK/tree) + 50 kg FYM + Azospirillium (250 g) + 100 g potassium mobiliser (T6) recorded maximum plant height (5.79 m), girth (64.91 cm) and plant spread in east-west (5.63 m) and north-south direction (5.46 m) than the other treatments. The treatment T8 consisting of half (1000:500:1000 g NPK/tree) + 50 kg FYM + 5 kg vermicompost + 100 g potassium mobiliser recorded maximum number of fruits (230.31 / tree), fruit weight (261.48 g), yield (60.22 kg /tree) and also have a significant improvement in terms of TSS (19.66 0Brix), total sugars (16.48 %), ascorbic acid (33.56 mg/100 g pulp), â-carotene (6935 μg/100g pulp) and shelf life (9 days) at room temperature as compared to other treatments, concomitant with higher values of soil (N-198.22 kg/ha, P-58.44 kg/ha and K-326.93 kg/ha) and leaf nutrient (N- 1.77 %, P-0.67 % and K-1.08 %) contents
Effect of Calcium, Boron and Sorbitol on Fruit-Set, Yield and Quality in Mango Cv. Himsagar
An investigation was carried out to study the effect of foliar spray of micronutrients, viz, calcium and boron and sorbitol on fruit-set, yield and fruit quality in mango (Mangifera indica L). cv. Himsagar, at Bidhan Chandra Krishi Viswavidyalaya, Regional Research Station, Gayeshpur. The experiment was laid out in Randomized Block Design (RBD), with three replications. Results revealed that boric acid (0.02%) + sorbitol (2.0%) were the most effective for enhancing fruit-set (1.58%), yield (48.51 kg tree-1), fruit weight (165.6 g), TSS (18.59°Brix), total sugars (14.92%) and ascorbic acid content (20.32 mg 100 g-1), while, calcium nitrate (Ca-0.06%) + boric acid (B-0.02%) proved to be the most effective for increasing shelf life in mango cv. Himsagar, at ambient room temperature

Choudhury, Hrishikesh, Mukhim, D. Khlur B., Dey, Abhinit, Warbah, Deisakee P., Sarma, Dandadhar (2019): Schistura syngkai, a new fish species (Teleostei: Nemacheilidae) from Meghalaya northeast India. Zootaxa 4701 (2): 185-191, DOI: 10.11646/zootaxa.4701.2.
Schistura larketensis, a new cavernicolous fish (Teleostei: Nemacheilidae) from Meghalaya, Northeast India
Schistura larketensis, a new species of cavernicolous loach, is described from Khung, a limestone cave in Meghalaya, India. The species differs from Schistura papulifera, its troglomorphic congener from northeast India, in having a smooth ventral surface of the head, the presence of a small cylindrical axillary pelvic lobe, and the presence of three pores in the supratemporal canal of the cephalic lateral-line system. Apart from these differences, the species can be immediately distinguished from all other species of Schistura from the Brahmaputra River and neighboring basins by the complete absence (or vestigial presence) of eyes
