Knowledge of the vegetative and reproductive characteristics of soybean cultivars with different growth habits and maturity groups is essential for the selection of a suitable variety as well as for providing optimum conditions for their growth. In 1994 in a field located in Kholenjan of Isfahan, Iran, nine indeterminate type cultivars belonging to different maturity groups, namely Williams, Wo...

The purpose of this study was to describe the correlations between wheat grain yield (GY) and its components, under environmental stress and non-stress conditions, and recognition of the most effective yield components and their development stages in making interaction with the environment. Two generations of F3 and F4, produced from a cross between Oste-Gata (drought tolerant) and Massara-1 (s...

This study was carried out in order to determine the more suitable seedling age on rice cultivars in Chaparsar Rice Research station of Mazandaran province in 2009. This experiment was laid out as split plot in a randomized complete block design with 3 replications. The main plots were seedling age with four levels (20, 33, 37 and 40 days) and sub plots were rice cultivars (Hashemei, Khazar, hy...
