In order to determine the optimal rates of Pertilachlor and Sunrice-plus herbicides for weed control of rice (Oryza sativa Var.Tarom Hashemi), a factorial experiment was conducted with a randomized complete block design with four replications in Rice Research Farm of Faculty of Agriculture, University of Guilan, Rasht, northern Iran. The first factor was weed control treatment which consiste...
in order to examine of the weed damage on corn and determination of the most suitable index for corn (zea mays l.) yield reduction in field condition and multi-species weed competition, an experiment as an interval mapping was carried out in the researching field of mashhad university during 2008-2009. treatments were complete control (pre-planting treflan and hand weeding), no control (no herb...
bacteriorhodopsin operates as a light/proton transfer pump which converts the light energy into a proton gradient. energy stored in the proton gradient can be used in a variety of ways. bacteriorhodopsin producing sources are some halobacterium species such as halobacterium sodomense and halobacterium salinarum which continue to grow in harsh and salt-saturated conditions. two types of red pigm...
Tuber and root crops virtually exclusively accumulate storage products in the form of carbohydrates. An exception is yellow nutsedge (Cyperus esculentus) in which tubers have the capacity to store starch and triacylglycerols (TAG) in roughly equal amounts. This suggests that a tuber crop can efficiently handle accumulation of energy dense oil. From a nutritional as well as economic aspect, it w...
Rice is an important cereal crop of global interest based on its daily uses. It was observed that the average yield rice low than potential production due to traditional growing techniques and weed intensification. Recently, intensification system (RIS) has emerged as alternative conventional cultivation system. A two-year field study carried out investigate impact seedling age (14, 21 & 28...
Imazosulfuron is a new herbicide recently labeled in drilland water-seeded rice under the trade name LeagueTM. Research was conducted to understand the best fit for imazosulfuron in Arkansas rice culture, prior to its anticipated launch in 2011. Specifically, research was conducted (a) to understand the influence of application rate and timing on control, (b) to evaluate the effectiveness of im...
