While no-till (NT) cropping systems can provide conservation benefits in the northern Corn Belt, adoption has been low due to concerns about potential yield reductions and economic risk. Strip-tillage (ST) systems have been proposed as an alternative that may provide many of the conservation...

We build the influence function empirical model of China's grain production at the present stage in view of the factors influencing direct grain subsidies, using Cobb-Douglas production function model. And we estimate the elasticity coefficient of impact of China's direct grain subsidies on...

On the basis of empirical data concerning "four agricultural subsidies" in Chongqing City, we establish panel data model to analyze the general effect of "four agricultural subsidies" on grain yield, and the structural effect of "four agricultural subsidies" on grain yield. Based on the F-test...

By using correlation analysis method, regression analysis method and time sequence method, we combine time and space, to establish grain geld spatio-temporal regression prediction model of Henan Province and ail prefecture-level cities. At first, we use the grain geld in prefecture-level cities...

A study was carried out in the Teaching and Research Farm of Delta State University, Asaba Campus from August to December in 2005 and repeated between March and July, 2006 to evaluate the response of maize (Zea mays) to liquid organic fertilizer. The study was conducted using a split plot fitted...
