... In the top eight sorghum-growing districts mentioned in section 2.1, overall fertilizer use in 1978-80 varied from 5.5 to 22.7 kg/ha N + P2O5 + K2O. In some of these districts sugarcane is an important crop, the growing of which affects the pattern of fertilizer Indirect estimates also show that, assuming 80% of all-India fertilizer consumption is used on four c r o p s rice , wheat, sugarcane, and cotton (NCAER 1978; Sohbti 1979)—the remaining 20% amounts to an overall 13 kg/ha N + P 2 O 5 + K 2 O in the remaining 100+ million ha under all other crops, including well-fertilized plantations and other cash crops 2 . Although general indications are that sorghum does not receive much fertilizer, some systematic efforts in technology transfer have led to the use of fertilizers, an increase in crop yields, and higher net returns from sorghum cultivation (Aswathaiah and Krishna 1975; Chandrasekhar 1979; Sanghi and Rao 1982). ...
... In most developing countries of the tropics, the bulk of food consumed is derived from small scale agriculture. The cropping systems of these countries are characterized by the landholding of few hectares, limited mechanization, low levels of purchased inputs, intensive labor, and multiple cropping that include intercropping as its mainstay (FAO, 1983;Francis, 1986). Although risk minimization is the major objective of intercropping in developing countries, small farmers also view intercropping as a potential system for diversification and intensification of production on their smallholdings. ...
... Biological pretreatment uses microorganisms and their enzymes selectively for delignification of lignocellulosic residues and has the advantages of a low-energy demand, minimal waste production and a lack of environmental effects. In biological pretreatment processes, microorganisms such as brown-, white- and soft-rot fungi are used to degrade lignin and hemicellulose in waste materials Schurz ( 1978). White-rot basidiomycetes possess the capabilities to attack lignin. ...
... The background for my original article (2), the purpose for which it was written and the assumptions for the model have not been adequately represented. Also, contributions (3,4) relevant to the argument are not among the references. ...
... Since the yield increase is proportionately more than the corresponding incremental labour applied, fertilizer use increases labour productivity. As fertilizer production, distribution and consumption increase, backward and forward linkages create additional employment, which is extremely important in labour surplus countries (Mudahar, 1978). ...
