Abstract

Diversity of butterflies in Nature Awareness Centre Trambri, Sundernagar was studied during different seasons during the October 2011-2012. 49 species of butterflies belonging to 38 genera and 5 families were recorded during present study. Nymphalidae was found to be the dominant family in all the seasons. Species richness was found to be maximum during the rainy season.

Abstract

Studies were conducted to investigate the effect of five growing mediums and four levels of inorganic phosphorus on the growth and development of Dendrocalamus hamiltonii planting stock under mid-hill conditions of north-western Himalayas. The growing medium and phosphorus levels significantly influenced various growth and development traits individually as well as in combinations. The growing medium viz., sand + soil + FYM (1:1:1) proved to be significantly superior for enhancing height and diameter growth of the tiller's, number of tiller per sapling, number of nodes per tiller, number of ischolar_mains, length of ischolar_mains, number of rhizomes, dry weight of stem, ischolar_mains, rhizomes and underground biomass. Among the various levels of phosphorus, 5 g SSP/propagule significantly proved to be the best dose. In combination effect, the maximum dry weight of rhizome (2.82 g plant^-1 ) and underground biomass (9.69 g plant^-1 ) was recorded in the propagules grown in sand: soil: FYM (1:1:1 ) and supplied with P @ 5 g SSP/propagule.

Abstract

Dendrocalamus hamiltonii Munro was evaluated for the effect of month of planting, spacing and phosphorus application on survival, growth, rhizome-genesis, biomass partitioning and P-uptake in macro-proliferated stock. April planted propagules significantly excelled over July ones for all of these traits. Two to three times more dry biomass of stem, ischolar_mains, rhizome and underground biomass per sapling (g) production was recorded in April planted propagules as compared to propagules planted in July. P-uptake was also higher in April planted propagules than July ones. Spacing of 30 cm × 30 cm resulted in maximum growth, development, biomass production and biomass partitioning and Puptake than 30 cm × 15 cm and 15 cm × 15 cm spacing. Phosphorus application @ 5 g SSP per propagule resulted in maximum growth, development, rhizome-genesis, dry weight of stem and underground biomass. Higher dose i.e. 10 and 15 g SSP per propagule showed slight depressing effect.
