Abstract

Effects of different PREPLANTING treatments on yieldwere compared with burning the plant residue after harvest as traditional farming system(a6), and with no RESIDUALS left from previous crop (a8). PREPLANTING treatments were: mixing the total WHEAT straw produced by previous crop with soil (a3), mixing WHEAT crop RESIDUALS after taking out straws from the field (a4), sowing a plant (as GREEN MANURE) with total WHEAT straw (aI, a5), and using green manure with previous crop residual after removing a part of straws from the field (a2, a7). These PREPLANTING operations were combined with three levels of chemical fertilizers; i.e. b1 for high yielding potential (to produce 7 tons/ha grain yield), b2 for medium yielding potential (to produce 5 tonslha grain yield), and b3 for ordinary yielding potential (to produce 3 tons/ha grain yields). The experiment was conducted at the experimental farm, College of Agriculture, Charnran University, during planting season (1999-2000). The PREPLANTING treatments were applied in early fall season and the main crop was planted in December. The following results were obtained from the analysis of the data included after harvesting in May. Mixing the whole straws with soil increased grain yield of WHEAT because of enough soil humidity for relative straw decomposition (52.2 mm rainfall in fall 1999 before sowing). The same situation was observed for medium level of fertilizer consumption. Mixing the .total straws with soil, despite common ideas, increased WHEAT grain yield because of its positive effect on the process of organic matter in the soil. The average amounts of organic matter in the soil varied between 0.511 and 0.713 percent five months after by applying different preplanting treatments compared to control treatment. These promising findings, if confirmed by additional studies in future, can be nominated as PREPLANTING treatments and effectivetechniques for increasinggrain yield.
