Abstract

A complete package of practices for commercial cultivation of Hedychium spicatum Ham. ex. Smith , Valeriana wallichii DC. and Roscoea purpurea Royle were worked out at National Bureau of Plant Genetic Resources , Regional Station , Shimla. The seed rhizomes weighed about 40-50 g of H. spicatum planted at a row-to-row and plant-to-plant distance of 45cm × 30 cm in the furrows at depth of 10-12cm and applied with well rotten FYM at the rate of 30-35 tonnes/ha and have given yield of 115-120 q/ha matured rhizomes after 2 years. Planting of V. wallichii into rows 40-50 cm apart and at 20-30 cm spacing between plants along with a dose of 35-40 tonnes FYM yielded 70-75 q/ha fresh ischolar_main mass and dried ischolar_main mass of 20-25 qlha. its autumn harvest (September-October) after two years is considered optimal. The seed tubes of R. purpurea weighed 4-5 g gave yield of 25-30 q/ha when sown in furrows with row-to-row distance and plant-to-plant distance of 30 × 15cm at 8cm depth and applied with FYM dose of 25-30 tonnes/ha.

Abstract

Larvae of three geometrid species including Hyposidera talaca, Ectropis bhurmitra and Pingasa chlora were recorded for the first time as defoliators of Paulownia fortunei in India. These were found causing multiple defoliation to the plants. Hyposidera talaca was found to be a major defoliating pest of P. fortunei causing high level infestation while E. bhurmitra and P. chlora were recroded as minor pests.

Abstract

Larvae of six lepidopteran species belonging to family Lymantriidae including Orgyia postica, Callitearagrotei, Euproctis virguncula, Euproctis fraterna, Euptoctis sp. and Dasychira sp. were recorded for the first time as the pests of Paulownia fortunei in India causing multiple defoliation to the plants. Systematic regular survey and samplings were conducted in Paulownia nursery and plantation as per randomised systematic design to understand the nature of damage, pest status and population fluctuation of different lymantriid species. Orgyia postica was found to cause high level infestation rendering it to be a major defoliating pest of P. fortunei while remaining species caused low to moderate injury to the foliage. Population size of lymantriid species showed positive correlation with temperature and humidity conditions.

Abstract

A study was undertaken in western region Haryana comprising Bhiwani, Fatehabad, Hisar, Jind and Sirsa districts to estimate soil organic carbon stock under different land uses viz. forests, block plantations, horticulture, agroforestry and agriculture. Maximum organic carbon stock was found in the soils under forests (40.26 Mg ha^-1). It was followed by plantation (33.27 Mg ha^-1), horticulture (25.69 Mg ha^-1), agroforestry (21.98 Mg ha^-1) and the least SOC stock was under agriculture (18.10 Mg ha^-1). Total soil organic carbon stock under forests was 1.22 million tons, out of these, Jind district has the maximum SOC stock (3, 17, 898.62 Mg). Least SOC stock was in Fatehabad district (1, 16, 086.27 Mg). Total SOC stocks under horticulture was 5, 23, 476.12 Mg, out of this, Sirsa district has 2, 64, 919.95 Mg and the least SOC stock was in Jind district (36,537.21 Mg). Soil organic carbon stock in Abubshehar Wildlife Sanctuary was 47, 7578.17 Mg and in Bir Bara Van Conservation Reserve was 19,490.85 Mg.
