Abstract

Forest loss due to shifting cultivation (jhum) is believed to have intensified in recent years, primarily due to increasing population pressures and shorter fallow cycles. This study aims to examine the physiochemical properties and microbial population in forest soil and soil under shifting cultivation (jhum) in Mizoram, India. Soil samples were collected randomly in forest and shifting area using three depths (0 – 15 cm, 16 – 30 cm and 31 – 45 cm). Forest soil exhibited higher nitrogen (N) level, organic carbon content, moisture content and microbial diversity compared to shifting cultivation soil, which showed slightly higher phosphorus (P) level and comparable potassium (K) concentrations. Correlation revealed that forest soil had lower bulk density and higher water-holding capacity, linked to their enhanced organic matter and microbial activity. Additionally, shifting cultivation was associated with soil compaction, reduced nutrient availability and lower microbial populations, highlighting the negative impact of land-use change on soil health and ecosystem functioning. Moreover, these findings emphasize the need for sustainable land management practices to mitigate soil degradation and support soil fertility in shifting cultivation system

Abstract

Parkia timoriana (DC) Merr (popularly known as tree bean) is a leguminous tree species found distributed in several South-East Asian countries like Indonesia, Japan, Malayasia, Phillipines, Thailand, Vietname including the mid and foothills of eastern Himalayas. We identified the seed source of this species and grouped them into different agro climatic zones based on moisture index and precipitation. The resultant agroclimatic zones were analysed for significant influences on quantitative traits of seeds and seedlings of P. timoriana and their contribution to germination and growth. Analysis of variance showed significant variation (p humid > subhumid > perhumid. We recommend tree breeders to chose of P. timotiana from arid zone (MI = -20 to -60) for establishing seed orchard for optimum yield. Further, ARCGIS interpolation tool could be of use for predicting better seed source of this species in plantation programmes.
