Abstract

Bambusa vulgaris was multiplied by burying whole culms during 2014 and 2015 at the Research Farm of ICAR-Central Agroforestry Research Institute, Jhansi. Two-year-old bamboo culms produced higher number (165) of shoots than 1-year (114) and 3-year-old culms (57). The culm planting method resulted in prolific ischolar_maining pattern during monsoon season, and on an average 5.7 ischolar_mained plants were obtained from every alternate node. Rooted sprouts were separated from each productive node along with fibrous ischolar_mains attached to it and were planted in polythene bags as new plantlets. This method of planting was found impressive for developing live bamboo fence and producing a large number of plants from scarce planting material. This technique promises a large number of planting material and readily acceptable technology to the farmers.

Abstract

Fine ischolar_mains are the most important contributors of ecosystem productivity in many terrestrial ecosystems. However, its dynamics, biomass potential, production and turnover rates of fine ischolar_mains under different environments lack clarity. We have studied horizontal and vertical distribution of fine ischolar_main dynamics, including length, density, biomass, production and turnover rates in Phyllanthus emblica-based agroforestry system in stressed environment of red soil patch of Bundelkhand region in Central India. Nearly, 63% of the fine ischolar_main length and its density are confined to 0– 45 cm soil depth. Fine ischolar_main biomass significantly varied across seasons with 70–80% of the biomass obtained during autumn, followed by spring and summer seasons. The annual fine ischolar_main production rates were highest near the stem base up to 1.0 m distance and the turnover rates varied from 1.63 yr^–1 (highest) at 0.5 m distance to 1.03 yr^–1 (lowest) at 1.5 m distance from the stem base. The fine ischolar_main dynamics changed highly across seasons, indicating more vigorous vegetative growth and nutrient release during monsoon months. Thus, studies on fine ischolar_main dynamics can improve our understanding of overall system productivity and management under stressed environments.
