In order to improve the performance of tillage tool for straw incorporation in silty clay loam, a combined implement with plough and rotary tiller was designed. Its on power consumption investigated, types (CTSR CTDR) were compared traditional including sole type (SP DP), (RT), two-pass (SP+RT DP+RT) rice field experiment. The effect forward speed RT CTSR studied by DEM simulation. ratio covera...
More efficient resource use, especially nitrogen (N) in agricultural fields could considerably reduce the losses and spillover effects on environment. Cereal-legume mixtures can lead to more uptake of growth-limiting resources, increase stabilize yields, due variation functional traits that facilitate partitioning niche space. Here we identify crop with optimal N use two selected cereal-legume ...
The numbers of greenbugs, Schizaphis graminum (Rondani), and bird cherry-oat aphids, Rhopalosiphum padi L., per wheat tiller (stem) were estimated in 189 production winter wheat (Triticum aestivum L.) fields located throughout Oklahoma. Taylor's power law regressions were calculated from these data and used to construct fixed precision sequential sampling schemes for each species. An evaluation...
Due to the existence of salinity and high temperature and sensitivity of some plants in most regions of Iran, especially in Khoozestan, there are a lat of difficulties in the planting and husbandry of lawn. Therefore an experiment was carried out under field conditions, to investigate the effect of seven levels of salinity as: Karun river water with EC of 1.09, distilled water (0.01) and irriga...
Genetic variability, correlation and path coefficients for fifteen agro-morphological traits were studied on 100 oat lines including two checks. Genotypic phenotypic of variation high leaf number per tiller weight panicle. Traits such as plant, tiller, panicle, stem width, individual plant yield, length internode thousand seed showed heritability accompanied by genetic advance indicating that t...
Tiller number (TN) is an important trait that contributes to yield in rice (Oryza sativa L.). A set of 76 chromosome segment substitution lines (CSSLs) derived from the super-hybrid cross between Zhonghui 9308 (ZH9308) and Xieqingzao B (XQZB) was used map quantitative loci (QTL) controlling tiller (TN). total four QTLs were detected Fuyang, Zhejiang Province (30.15° N, 120° E). Two Lingshui, Ha...

applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...
شباهت ظاهری بین گونه های برگ باریک جنس festuca l. منجر به استفاده از صفات پنهان مانند صفات تشریحی برای اهداف تاکسونومیک شده است. ساختار و آرایش بافت اسکلرانشیمی و تعداد رگبرگ ها به طوری که در برش عرضی برگ قابل مشاهده است دارای قابلیت های تشخیصی مهمی در تعدادی از اجتماعات گونه ای در جنس festuca هستند. تعداد 53 جمعیت منتخب از گونه های festuca، شامل نمونه های جمع آوری شده از سرتاسر کشور، نمونه های...
