The effect of 15 planting dates on various growth characteristics of peas var. Dark Skin Perfection was studied in outdoor pot experiments at Vancouver and Agassiz, B.C. Differences in growth and yield between locations and planting dates were partly accounted for by the mean of maximum temperatures for the growth period.At Agassiz where temperatures exceeded the optimum for most growth characteristics in many of the later plantings, the mean of maximum temperatures was negatively correlated with total dry-matter yield, peas per pod, and pea yield; was positively correlated with branching; and had no effect on pods per plant, double-podded nodes, and tillering. At Vancouver, where temperatures were suboptimum for the early plantings and approached optimum for the later plantings, the mean of maximum temperatures was positively correlated with total dry-matter yield, pods per plant, double-podded nodes, tillering, and pea yield but had no effect on peas per pod or branching. A seasonal mean maximum temperature of 68 to 70°F was considered to be optimum for peas.

This research was conducted to determine performances of seven alfalfa cultivars with different fall dormancy rates in terms of dry matter yield and some quality parameters under Mediterranean conditions throughout the years of 2007-2009. In the study, cultivars were evaluated for dry matter yield (DMY), leaf/stem ratio (LSR), crude protein (CP) content, crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM) content and relative feed value (RFV). According to average of two year results, there were significant differences among alfalfa cultivars in terms of all characters studied. Mean DMY, LSR, contents of CP, ADF, NDF, DDM and RFV were determined as 18.147 t ha-1, 0.82, 17.4 %, 41.0 %, 49.0 %, 56.9 % and 114. The highest DMY averaged over two years was obtained from cultivar Nimet while lowest one was obtained from Magnum 5. As a dormant cultivar, Magnum 5 was superior in terms of LSR and CP content to the other alfalfa cultivars and it was lower in ADF and NDF content than the others. It was concluded that cultivar Nimet with the highest DMY and CPY yields can be recommended as a non-dormant cultivar for farmers in regions of Turkey with the Mediterranean climate.

This experiment was conducted to determine the effects of mixture rates of hairy vetch with oat, barley and wheat on dry matter yield and its quality and to determine the suitable mixture when grown as catch crop at Uludag University, Faculty of Agriculture, Agricultural Research and Application Center, Bursa Turkey during 2011-2012 and 2012-2013 growing seasons. The experimental plant entries were Menemen-79 variety of hairy vetch, Faikbey cultivar of oat, Akhisar-98 cultivar of barley and Flamura cultivar of wheat. Nine mixtures (25 % oat:75 % hairy vetch, 50 % oat:50 % hairy vetch, 75 % oat:25 % hairy vetch, 25 % barley:75 % hairy vetch, 50 % barley:50 % hairy vetch, 75 % barley:25 % hairy vetch, 25 % wheat:75 % hairy vetch, 50 % wheat:50 % hairy vetch, 75 % wheat:25 % hairy vetch) were used. Several parameters such as dry matter yield, leaf area index, light interception, crude protein content and yield; ADF (acid detergent fiber) and NDF (neutral detergent fiber) contents and relative feed value have been examined in the experiment. The highest dry matter yield was obtained from the mixtures of 50 % oat:50 % hairy vetch (12 040 kg ha-1) and 75 % oat:25 % hairy vetch (11 748 kg ha-1). According to the two-year results, the higher and quality hay yield (low in ADF and NDF values, high in relative feed value) was produced at 50 % oat:50 % hairy vetch mixture, and this mixture have been proposed to the experimental conditions due to its suitability.
