Abstract

It is noted that yields from rice-wheat cropping systems in the Indo-Gangetic plain are declining despite the increasing use of chemical fertilizers. Crop residues are important components of soil fertility management, but are burnt in some areas, such as Punjab, India. Not only does this mean a loss of nutrients but also causes environmental pollution (and the associated health effects): the production of substantial quantities of carbon dioxide. Limited published data suggest that rice-straw can be converted to high value manure of a better quality than that of farmyard manure. Its use, along with chemical fertilizers should not only sustain present levels of crop yields, but may also increase them. Data are presented from 237 farmers surveyed during September-October 1996
