the reaction of kochia (kochia scoparia) ecotypes to sowing date in mashhad weather condition
kochia is one of those plants which have capability to grow in different environments and can be used as a valuable plant to produce biomass and seed. the purpose of this study was to evaluate the possibility of kochia planting in different dates as well as its resistance to cold weather of mashhad winter. seven sowing dates including 10th october, november, march, april, may, june and july and...
متن کاملKRN4 Controls Quantitative Variation in Maize Kernel Row Number
Kernel row number (KRN) is an important component of yield during the domestication and improvement of maize and controlled by quantitative trait loci (QTL). Here, we fine-mapped a major KRN QTL, KRN4, which can enhance grain productivity by increasing KRN per ear. We found that a ~3-Kb intergenic region about 60 Kb downstream from the SBP-box gene Unbranched3 (UB3) was responsible for quantita...
متن کاملEffect of sowing date on seed yield and yield components of canola (Brassica napus L.) cultivars in north Khuzestan conditions
Determination of optimum sowing date plays an important role in crop management and achieving the higher yield. To study the effectof sowing date on seed yield of canola cultivars, a filed experiment was carried out as strip split plot block arrangement in randomized completed block design with three replications in 2017-18 and 2018-19 cropping seasons at Safiabad Agricultural and Natural Resou...
متن کاملUsing simulation models to investigate the cumulative effects of sowing rate, sowing date and cultivar choice on weed competition
With the increasing pressure on crop production from the evolution of herbicide resistance, farmers are increasingly adopting Integrated Weed Management (IWM) strategies to augment their weed control. These include measures to increase the competitiveness of the crop canopy such as increased sowing rate and the use of more competitive cultivars. While there are data on the relative impact of th...
متن کاملSoybean Sowing Date: The Vegetative, Reproductive, and Agronomic Impacts
The sensitivity of soybean [Glycine max (L.) Merr.] main stem node accrual to ambient temperature has been documented in greenhousegrown plants but not with fi eld-grown plants in the north-central United States. Biweekly V-node and R-stage, stem node number, internode length, and other traits were quantifi ed in an irrigated split-plot, four-replicate, randomized complete block experiment cond...
