Read More Background and Objectives Wheat cultivars that have suppression potential of weeds besides high yield can be a weed management method in sustainable agriculture. Materials and Methods In order to study the competition ability of some wheat cultivar with wild oats in three planting dates, a field experiment as factorial in complete randomize blocks with three replications was carried out at the Agricultural Research Station of Shahid Chamran University in 2013-2014. In this experiment, the factors included planting dates (16th November, 1st December and 16th December), wheat cultivars (Star, Chamran and Virinak) and competition with wild oats (with wild oat, without these weeds). Results The result showed, in the competition status, Star cultivar had a higher grain yield than other cultivars in the first planting date (16th November) whereas, it had no significance different with Star and Chamran in the second planting date (1st December). When the cultivars were planted as monoculture, the highest grain yield belong to Star in the first planting date followed by the second planting data. In this condition, Virinak and Chamran in the first planting date had the lowest grain yields. Effect of the planting date on grain yield was the same trend as grain/spike; however, the high correlation with grain/spike (81%) and with thousand grains weight (59%) confirmed it. Three cultivars obtained the highest of competition index in 1st December. Although the competition and planting date resulted in decrease of grain yield, according to this investigation, the best planting date was determined 16th November and 1st December for Star cultivar. When the planting was delayed (16th December), virinak was a better choice. Discussions According to the different growth, competitive and morphological characteristics of wheat cultivars, their responses varied in different planting dates in competition against wild oats. The grain yield of Chamran, Star and Virinak cultivars decreased 27, 25 and 23 respectively by competition with wild oats. In this respect, the dry matter of planted wild oats on 1st December than the former and latter planting dates was further damaged by every three wheat cultivars (Star, Chamran and Virinak) besides higher grain yield of wheat cultivars whereas the climatic conditions of this year with previous years differed, suggesting wheat planting with short delay as an agronomy method was assayed in the different years with regard to temperature and hydrothermal effect on wild oats germination and growth in comparison with wheat.

Read More Stomata have a sensitive role in plant physiology aspect investigation, specially under stress conditions. This experiment was carried out in Ahvaz Shahid Chamran University Research Field in 2005 and 2006 under randomized complete block design with 4 replications. The main plots included three planting date (6 November, 26 November and 16 December) and the subplot were three wheat cultivar (Fong, Chamran and Star). The results showed that the deterrence of the aweraye of flag leaf water potential under planting date treatment was significant (1% level), but flag leaf water potential under different cultivars and the interaction between planting date and cultivars was not significant. RWC (relative water content) was different during grain filling and in four sampling in difference planting date and in cultivars for many sampling observed significant difference but the difference was not significant in cultivars interaction and planting date. Stomata conductance in different grain filling stages in planting date showed significant difference. Also under cultivars, there was a significant difference (1% level) but their interaction was not significant. The most stomata resistance was in third planting date and mean comparison of this character in cultivars showed that near the end of grain filling. The highest and lowest stomata conductance was in Fong and Chamran cultivars, 0.93 and 0.67 cm/s respectively. Planting date interaction and cultivar showed that the first sampling exception, in other grain filling period SPAD number influenced by them and in fourth sampling (28 days after flowering) the first and third planting date allocated 41.34 SPAD number to themselves respectively. Grain filling period coincident with heat stress in near the end of season, induced that effective parameters in yield (ψp, RWC, gs and chlorophyll density) located in undesirable conditions. Changing the planting date (late planting date) which caused coincident grain filling to more heat stress and made the sever effective on grain weight compare to biomass as effective of planting date on grain (1% level) had significant different and maximum seed single dry weight was 45.16 and 36.39 mgr in the first and the third planting date respectively. Also, early Fong cultivar with better use from environmental condition got high yield compared to other two cultivars.
