The study aimed at quantifying the rates of soil CO 2 efflux under the influence of common tillage systems of moldboard plow (PT), chisel plow (CT), rotary tiller (RT), heavy disc harrow (DT), and no-tillage (NT) for 46 days in October and November in a field left fallow after wheat harvest located in southern Turkey. The NT and DT plots produced the lowest soil CO 2 effluxes of 0.3 and 0.7 g m (2 h (1 , respectively, relative to the other plots (P B0.001). Following the highest rainfall amount of 87 mm on the tenth day after the tillage, soil CO 2 efflux rates of all the plots peaked on the 12th day, with less influence on soil CO 2 efflux in the NT plot than in the conventional tillage plots. Soil evaporation in NT (64 mmol m (2 s (1 ) was significantly lower than in the PT (85 mmol m (2 s (1 ) and RT (89 mmol m (2 s (1 ) tillage treatments (P B0.01). The best multiple-regression model selected explained 46% of variation in soil respiration rates as a function of the tillage treatments, soil temperature, and soil evaporation (P B0.001). The tillage systems of RT, PT, and CT led, on average, to 0.23, 0.22, and 0.18 g m (2 h (1 more soil CO 2 efflux than the baseline of NT, respectively (P 50.001).

The present investigation aimed to understand the effects of dressing fertilizers and different nitrogen (N) doses on yield and nutrient uptake of chickpea (Cicer arietinum L.) plant. The study has been carried out with three repetitions under the greenhouse conditions. Nitrogen doses were; 0 kg N ha-1, 30 kg N ha-1, 60 kg N ha-1, 90 kg N ha-1 and 120 kg N ha-1 (in CaNO3.4H2O form) and dressing fertilizers were applied as 40 kg N ha-1. The results indicated that the dressing fertilizer application significantly increased average shoot dry weight with 8.18 g poƒ-1. Also, N (2.88 % N), P (0.40 % P), K (3.90 % K) and Fe (114.2 mg kg-1) concentrations increased with dressing fertilizer application of chickpea plant as compared to without dressing fertilizer application. However, dressing fertilizer application did not affect Mg, Zn, Mn and Cu concentrations of chickpea plant. Generally, in this study dressing fertilizer application increased yield and some macro and microelements concentrations of chickpea plant.
