Effects of sowing dates and cultural treatments on growth, quality and yield of processing beans.

The objective of this study was to evaluate the effect of windbreak and sowing dates on growth and yield of bean varieties; Amboto, Gina, Nashau, Volare. Two different treatments of cultural practices (windbreak/no windbreak) were applied all cultivars and sowing dates. The experimental design was a randomized block in a split plot with three replications. Seeds were sown in well prepared soil on 23.07.2004 and 27.08.2004 in 1st year and 29.07.2005 and 29.8.2005 in 2nd year. Results are showed that sowing date, variety and windbreak generally exhibited significant positive influence on growth parameters and yield components. Yield was significantly decreased with later sowing date in all 2 years of research. Significantly better results were obtained in treatments when was used WB. Amboto performed better compared with other three varieties, mostly due to more yield per ha and per plant. Hence, Amboto is recommended for general cultivation of bean and SD, was the optimum sowing date of bean for Odemis condition.
