Chickpea (Cicer arietinum L.) seeds are a good source of protein and mineral nutrients. However, there is no information regarding harvest timing on yield and mineral composition of chickpea seeds. The effect of harvest timing on seed yield, some yield components and mineral nutritional value of seeds of field grown chickpea plants in two different sites were studied. The mineral composition of chickpea straw depending on harvest timing was also evaluated in order to explain the variations of seed mineral concentrations in sink-source relationship manner. Yield and mineral nutritional value of chickpea were significantly affected by harvest timing. When compared to the seed yield at optimal harvest time, seed yield was 18% and 9% lower in the early harvest and 27% and 31% in the late harvest in Site 1 and Site 2, respectively. Late harvest of chickpea crops resulted in significant pod dropping and shattering. Generally, protein, phosphorus (P), calcium (Ca), magnesium (Mg), copper (Cu), zinc (Zn)...

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.

The field experiment was arranged in split plots based on randomised complete block design with three replications. In order to eliminate the contamination, treatments (C:control, BI:bacteria inoculation, N: nitrogen fertilization, BI+N: bacteria inoculation+nitrogen fertilization) were in main plots and cultivars (Isik-05, Yasa-05, Azkan, Hisar) were sub-plots. According to two-year results, N caused significant increases in pod number per plant and seed number per plant, BI caused significantly increases in only pod number per plant. However N+BI had no positive effect over control. Thus, N and BI can not be suggested together. There were no significant differences among the cultivars with respect to seed yield and BI always caused same or higher seed yield. While cultivar Azkan produced similar seed yield in wet year, its performance was better in the dry year. Thus, cultivar Azkan and bacteria inoculation can be suggested together for sustainable chickpea production in central Anatolia and similar ecological conditions.

This research aimed to determine the effect of different levels of nitrogen (N) on the growth, yield and the N accumulation of lentil plants grown under rain-fed conditions. The two-year field experiments with lentil were arranged in a randomised complete block design. Nitrogen was applied at four rates (0, 20, 40 and 60 kg ha-1) and all of the plots received half of the N rates before sowing in October and the remaining N rate in spring. The plants were harvested in the following stages: the first multifoliate leaf unfolding at the fifth node (V5) full seed or seed on nodes 10-13 that fill pod cavities (R6) and maturity (R8). The dry weight and N concentration of the shoot (leaf+stem), pod wall, and seed were then measured. It has been found that N application significantly affected the lentil characteristics. The maximum biomass accumulation and N accumulation were obtained at R6, and the N fertiliser had a positive effect on the seed weight and N accumulation. It can be suggest that 20 kg N ha-1 will increase the per-plant dry matter and N accumulation of the seeds under rain-fed conditions.
