Effect of Different Soil Tillage, Weed Control and Phosphorus Fertilization on Weed Biomas, Protein and Phosphorus Content of Chickpea (Cicer arietinum L.)

Abstract

This research was carried out in Central Anatolian Region (Haymana, Turkey) throughout 2 years (2002 and 2003). The objective of this study was to determine the effects of different soil tillage methods, weed control and phosphorus fertilizer doses on yield and yield componenets of chickpea. The experimental design was split split plot with three replications. In the research, two different soil tillage methods (moldboard plow and rotary tiller), two weed control methods ( hand weeding and herbicide application) and three phosphorus doses (30, 60 and 90 kg P2O5 ha) were used. According to the results, different soil tillage methods and phosphorus fertilization did not have any effect on yield components. In addition to it, increasing levels of phosphorus had decreased the grains phosphorus content. Weed control methods had effect on dry weed biomass and grain yield. If weed control, by hand is not possible, herbicide application may advice as an alternative solution.
