India has a long tradition of agroforestry and many different types of indigenous agroforestry systems can be found in different parts of the country. Most of these systems are, however, very location-specific, and information on them is mostly anecdotal. Therefore, their benefits have remained vastly underexploited. The situation is now slowly but steadily(More)
Reduction in forage production (FP) under trees in the humid tropics is well known, but information on how different levels of nitrogen (N) fertilizer influence FP under trees is meager. The present study reports effects of four N fertilizer levels (0, 60, 80 and 120 kg ha−1 N) on net soil N mineralization rate (NMR) and soil moisture (SM), FP, shoot(More)
Productivity, sustainability and economics of agriculture, forestry and agroforestry land use practices were compared over a six year period in a split plot experiment on a moderately alkali soil of the Central Soil Salinity Research Institute, Karnal, India. Three commercial trees of the area formed the main plot treatments and four crop sequences were the(More)
This paper deals with the plant folk medicines among Nicobarese aboriginals of Katchal Island, in the Nicobar group, India. The tribals, living in complete geographical isolation, have been using folk medicines from time immemorial. Data on 65 plant species were gathered from experienced old men and women. Therapeutic applications and manner of using are(More)
Integrating fertilizer nitrogen (N) with organic manures can foster a sustainable agricultural system in subtropical soils low in organic matter. A two year field experiment was conducted on a sandy loam soil at Allahabad, India to evaluate the effect of incorporating spent white button mushroom compost (WB-SMC) with a narrow C:N ratio (15.18) and spent(More)
Ground water table (g.w.t.) levels were measured twice a month for 2 years in 50 observation wells installed inside and outside the two 18-year-old and 350 m apart plantations of Eucalyptus tereticornis (Mysure gum) at Dhob-Bhali research plot located in Rohtak district of Haryana state (north-west India). Throughout the study, the g.w.t. underneath the(More)
A balance sheet of nitrogen has been presented for an arable land in aCajanus cajan field. Quantitative inventory and transfer rates are suggested for several compartments. On the basis of data, it has been concluded that due to microbial activities appreciable nitrogen was returned to the available nitrogen pool by means of root and litter disappearance.(More)
Large areas in arid and semi-arid regions remain barren due to lack of irrigation. The underground aquifers in these regions are either saline or sodic. Groundwater surveys indicate that poor-quality water is used to irrigate arable crops in 25–84 % of the total groundwater development areas in north-western states of India. The present long-term study(More)
