In a greenhouse pot experiment conducted in the Experimental Research Greenhouse at Süleyman Demirel University Campus, and investigated the effects of irrigation water salinity on onion's bulb yield, evapotranspiration and salinity in soil's profile during 2001 with three replacement. Onion seedlings were transplanted on May 31 at the density of five plant per pot. The experiment was started on the transplanting date with the soil content of all pots at field capacity. Soil moisture status monitored daily by weighing of pots until harvest (December 2), and the data used to determine the daily evapotranspiration and quantity of irrigation. Plants in the pots were irrigated with tap water (controls, EC:0.8 dS/m,T0) or salinized water (EC:1.6 dS/m, T1; 3.2 dS/m T2; 4.6 dS/m, T3 and 6.1 dS/m, T4). Soils sampled at the transplanted day, beginning of the each growth period and harvesting day to determine the salinization of pot's soil. Within the range of electrical conductivity of the irrigation water between 1.6 dS/m and 6.1 dS/m decreased the onion's bulb yield (34-68 %) and evapotranspiration (15-35 %), significantly. At the end of the experiment, the electrical conductivity of the saturated soil extract in the treatment were formed from 0.54 to 0.81 dS/m (used T0) and 4.47 dS/m (used T4).

Potassium humate application (control and 2000 ml/ha), pea cultivars (Utrillo and Sprinter) and row spacing (20, 30 and 40 cm) were placed to main, sub and sub-sub plots, respectively. Seed sowing was performed in November in both years. Some plant traits such as the number of pod per plant, number of seed per pod, pod length, fresh pod yield, fresh seed yield, the ratio of fresh seed weight to fresh pod weight, seed ratio remained above 9.5 mm sieve, seed dry matter and crude protein content were also determined. The effects of potassium humate on the number of pod per plant and fresh pod yield per plant was significant as statistically. Dry matter content of seed was affected from potassium humate highly significantly. Highly significant differences were determined among the pea cultivars in terms of number of pods per plant, fresh pod and seed yield per plant, dry matter content of seeds, pod length, rate of fresh seed weight to fresh pod weight and seed weight remained above 9.5 mm sieve. The number of seeds per pod significantly differed among the pea cultivars. Sprinter cultivar was superior than Utrillo cultivar for the number of pod per plant (12.84), number of seed per pod (6.11), rate of fresh seed weight to fresh pod weight (50.56%). Fresh seed yield (26.44 g/plant) and pod yield (73.1 g/plant) of Utrillo cultivar were found higher than Sprinter cultivar due to having large pod and seeds. The effects of row spacing on the number of pod per plant, number of seed per pod, fresh seed yield per plant and seed crude protein content were significant. The highest fresh pod yield (71.4 g/plant) was obtained from 40 cm row spacing.

The mutants induced in wheat have potential not only for cross-breeding but also for direct release. The range and frequency of desirable mutants may differ with the mutagen and the genotype. The aims of the study were to determine mutant lines with good yielding properties compared to control for yield, yield components and some agronomic characters in the M4 and M5 generations. The lines used in the experiment were selected from mutant populations of durum wheat varieties (Sofu and Gediz-75) treated with gamma rays. The experiments were organized as a randomized complete blocks design with three replications. The mutants which have lower or higher means than control for investigated characters showed the potential of mutation breeding. The mutant means generally were at the mean level of the control in the M5 generation. Some mutants with the high grain yield in the both generations were determined to be better than the control for different characters. Such induced mutants also provide the breeding material for the M6 and subsequent generations and for genetic investigations.
