Yield response of maize (Zea mays L.) to crop residue management on two major soil types Of Alemaya, Eastern Ethiopia: I. Effects of varying rates of applied and residual N and P fertilizers
Field trials were conducted on two soil types for seven years (1988–1994) to investigate grain yield response of maize to crop residue application as influenced by varying rates of applied and residual N and P fertilizers. Yearly application of N and P fertilizers at both one-half and full recommended rates resulted in grain yield increases of more than 500 and 1100 kg ha-1, respectively over application of only crop residue. Moreover, grain yield responses due to residual N and P fertilizers applied only during the first year were found to be comparable to the yearly applications of these fertilizers. Rainfall and soil type have exerted considerable influences on the grain yield response obtained in this study. Grain yield exhibited a corresponding decrease with decreasing rainfall. Grain yield increases on Typic Pellustert were relatively higher than on Typic Ustorthent.
Objective To measure the distribution of the government subsidy among different economic groups in Zhe- jiang Province,and estimate their equity.Methods Used the data of National Health Service Survey of Zhejiang Province in 2003 and the Benefit Incidence Analysis(BIA).Results From the absolute equity side,either the in-patient and out- patient or total subsidy,the absolute equity of subsidies was bad;From the relative equity side,the relative equity of the in-patient subsidies was good,but the out-patient subsidy was bad.Conclusion There was some distance between the practical result and the ideal objective.The real beneficiary was not the poor but the better-off.
