ABSTRACT
Land races of soybean [Glycine max (L.) Merrill] namely Kulat brown, Mothi and Kulat white and improved varieties Weber-84 and NARC-II were compared for growth and vegetative development at NWFP. Agricultural University Peshawar during summer 2000, using Randomized Complete Block Design with four replications. All the parameters studied except percentage emergence, exhibited significant differences in means among the varieties. On the average Land races and improved varieties demonstrated 4.8 and 5.8 days to emergence, 80.5 and 80.9% emergence, 116.9 and 86.1 days to maturity, 75.8 and 64.7 cm plant height, 6075 and 5003 kg ha-1 biological yield and 21.9 and 25.5% harvest index, respectively. Land races on the average emerged one day earlier, matured one month later, produced 17% taller plants, produced one thousand kg extra biomass as compared with improved varieties. It is expected that with the above characteristics Land races could be utilized as potential fodder crop. Further research is suggested on grain yield potential and reproductive development in Land races.
