The different components of the agroforestry systems were analyzed for their natural enemy complex through a monthly sampling programme. Maintenance and potential role of natural enemies' complex in various compartments of such systems are discussed in the light of land use practices and holding size.

Such natural unit has evolved through rain water interaction with land mass, typically comprising arable land, non-arable land and natural drainage lines in rain-fed areas. Sustainable production depends on the health, vitality and purity of a particular environment in which land and water are important constituents. A pilot study was thus undertaken to study the geomorphology, land-use systems and their impact on water resource management on the Meghalaya Umbaniun micro-watershed. In this Micro-watershed (3951.18 ha), water body covers an area of 5.69ha (0.14%). The paper highlights the linkage between geomorphology, land use systems and its impact on quality of water resources on the Umbaniun Micro-Watershed, Meghalaya. Topographical and physical-chemical characteristics, such as pH, conductivity, dissolved oxygen, turbidity and water temperature, were used as environmental degradation indicators

The affected area under slash and burn farming still bears hard on soil condition and ecology of Mizoram. However, over the years, peasants of Mizoram have been practicing various forms of agroforestry. A large number of multipurpose trees and shrurbs(48 species recorded) are left deliberately or introduced in cropping system to increase the productivity. Govt. policy of promoting new farming technique, viz; Jhum Control Project - 1987 would have gone some way to relieve the compulsion of practicing Shifting Cultivation. The most common and successful practice is intercropping of Oryza sativa (Paddy) with Tectona garndis (Teak). This system is economically and ecologically sound.

Various researchers have proposed with shoot cuttings as a cost effective method for this noble tree species which natural regeneration limited by prolonged seed dormancy. The present study was conducted to investigate the interactive effect of growth stage of shoot and IBA concentrations on rooting during four seasons. Regardless of season, rooting was influenced by growth stage, IBA treatment and their interaction. Best rooting performance was exhibited by cuttings planted during rainy season. Cuttings from second year shoot scored the highest rooting percentage in all season (47.3% in rainy > 26.9% in autumn >10.2% in winter) except in spring where third year shoot (22.8%) had the highest value. Rooting of cutting was enhanced by IBA treatment. Highest rooting percentage during spring (22.9%) an...

Analyzing shape parameters and drainage pattern parameters is known to be very important in watershed management. The Umbaniun micro-watershed with an area of 3951.18 ha located at 25°27'29'' to 25°32'34'' North latitude and 91°47'10'' to 91°52'40' East longitude has an elongated shape with low sediment production rate (SPR) of 0.16218 ha-m/100 sqkm/year. It is under high biotic pressure and no conservation measures have been taken up to maintain its ecological health and stability. In this paper, we highlight a pilot study analyzing soil erosion and sediment production rate with reference to morphometric characteristics of the Umbaniun micro-watershed in Meghalaya.

Majority of the population (rural) depends on agriculture. Agriculture in the state is carried on in primitive ways with Jhuming prevailing in many parts. This practice is considered destructive as vast forest areas are cleared and burnt. Such areas are used for cultivation and left out. After a gap of few years (23 years as of now and 15-20 years in past the area is revisited for cultivation without allowing rejuvenating. The present work provides a status and trend of Land use land cover dynamics in parts (at watershed level) of Meghalaya. The geospatial tools have been used to assess (a) the changes in land use land cover since 1970s to 2007; (b) patch dynamics for understanding the degree of fragmentation; (c) changes along the terrain topography. New Shillong Township of Meghalaya is taken as experimental area, which is a representative of mid altitudinal watershed particularly in the East Khasi Hills district of Meghalaya. With the help of geospatial tools researcher tries to emphasis the landuse/ land cover dynamics of New Shillong Township area

Reckless exploitation and habitat destruction have greatly reduced its natural population. Its regeneration through seed is also poor, so focus has been paid on vegetative propagation by stem cuttings to augment its natural regeneration. The present study was carried out to evaluate the effect of different rooting media on rooting behavior of Taxus baccata cuttings under poly house conditions. Effect of ten rooting media was studied on rooting of juvenile and mature stem cuttings of Taxus baccata. Six substrates i.e. field soil, forest soil, river sand, FYM, peat and vermi-compost were used for preparation of rooting media. The experiments were laid out in a randomized completely block design. The different rooting parameters were evaluated after six months of planting. The results revealed that the highest value of per cent survived, per ce...

(Himalayan Yew) throughout the Indian Himalayan Region is greatly reduced due to its extensive and reckless exploitation for “Taxol” an anticancer drug. The effects of overexploitation are exacerbated by the species poor regeneration process, slow growth rate and prolonged seed dormancy. Therefore vegetative propagation by branch cuttings seems to be only practical solution for its large scale multiplication. A study was conducted on six candidate trees (CTs) to examine the effect genotype, physiological age of stem, IBA treatment on rooting of Taxus baccata cuttings. Results revealed that rooting behaviour of cuttings was significantly affected by all the factors under study. Among the six CTs studied, CT 2 (from BSI, Shillong) had given the highest rooting response (46.28%). The juvenile cuttings have the higher rooting capacity; however the callusing was more prominent in mature cutting. The influence of IBA treatment was also significan...
