TY - JOUR T1 - A Study on Response of Yield and Seed Yield Components of Red Bean (Phaseolus vulgaris L.)Genotypes to Delay in Planting in Miyaneh Region TT - بررسی واکنش عملکرد و اجزای عملکرد دانه ارقام لوبیا قرمز ( Phaseolus vulgaris L )به تأخیر در کاشت در منطقه میانه JF - JCPP JO - JCPP VL - 12 IS - 43 UR - http://jcpp.iut.ac.ir/article-1-825-en.html Y1 - 2008 SP - 105 EP - 115 KW - Seed yield component KW - Planting date KW - Red bean KW - Yield N2 - In order to determine the response of yield and seed yield components of red bean )Phaseolus vulgaris L. ( genotypes to delay in planting, this study was conducted in Factorial  experiment based on a RCB design with 3 replications in the Jahad-Keshavarzi Research farm of Miyaneh in 2006. Factors included cultivars in three levels(Naz, Gole and Sayad) and planting date in three levels (5 and 20 April, and 5 May). Results of variance analysis showed that the cultivars and planting dates had significant effects on all the characteristics. The interaction between cultivars and planting dates had significant effect on stem height, number of pod per plant, 100 seed weight, biological yield, grain yield and number of seed in pod. The Results of mean comparison indicated that SAYAD cultivar in the first planting date with 4033.3 kgha-1 and Gole cultivar in the third planting date with 1500.2 kgha-1 had the highest and lowest grain Yield, respectively. Total yield with all traits, except for the stem height, 100 seed weight and cultivar protein percentage showed a  positive and significant correlation. M3 ER -
