The capture of subsoil water by wheat roots can make a valuable contribution to grain yield on deep soils. More extensive root systems can capture more water, but leave the soil in a drier state, potentially limiting water availability to subsequent crops. To evaluate the importance of these legacy effects, a long-term simulation analysis at eight sites in the semi-arid environment of Australia...
با پیشرفت تکنولوژی و کاهش ابعاد ترانزیستور، تلرانس پارامترهای ساخت مدارات الکترونیک افزایش یافته و باعث کاهش ضریب yield می شود. در طراحی مدارات الکترونیک، طراح عموما مقادیر نامی را برای دست یابی به عملکرد مطلوب استخراج می کند، در حالی که، در عمل یک ناحیه تلرانس، به دلیل فرآیند های تصادفی حین فرآیند های ساخت، وجود دارد که بایستی در طراحی لحاظ گردد. الگوریتم های بهینه سازی طراحی تلرانس، ناحیه تلر...
chicory (cichoriumintybus l.) is an important industrial crop which is used for inulin production. inulin is widely applied as food ingredient due to its health promoting properties. for the first time, attempts were made to investigate thirteen endemic chicory genotypes including three pumilum populations, along with five root chicory cultivars, four witloof chicory varieties and a crispum end...
Climatic variability, typified by erratic heavy-rainfall events, causes waterlogging in intensively irrigated crops and is exacerbated under warm temperature regimes on soils with poor internal drainage. Irrigated cotton is often grown in precisely these conditions, exposing it to waterlogging-induced yield losses after substantial summer rainfall. This calls for a deeper understanding of mecha...
In a four-year experiment, five nitrogen rates (0, 60, 120, 180 and 240 kg N ha-1) were tested over irrigated sugar beets grown on clays, underMediterranean conditions, in centralGreece. There, sugar beets are commonly grown under water shortages, high temperatures and high soil Na concentrations. Contrary to previous reports, N rates did not affect significantly population density (as asse...
The current agricultural system is seeking a biological solution to lesson hazardous impacts from the use of chemicals control weeds in rice production. Plant allelopathy one ways where allelopathic plant inhibits its surrounding plants by releasing substances. present experiment was conducted at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during period July Decemb...
The rapid progress in rice genotyping must be matched by advances in phenotyping. A better understanding of genetic variation in rice for drought response, root traits, and practical methods for studying them are needed. In this study, the OryzaSNP set (20 diverse genotypes that have been genotyped for SNP markers) was phenotyped in a range of field and container studies to study the diversity ...
Enhancing water use efficiency of coriander (Coriandrum sativum L.) is a major focus for coriander breeding to cope with drought stress. The purpose of this study was; (a) to identify the predominant mechanism(s) of drought resistance in coriander and (b) to evaluate the genetic control mechanism(s) of traits associated with drought resistance and higher fruit yield. To reach this purpose, 15 h...
