in order to evaluate the influence of different sowing dates on quantitative and qualitative yield in four winter rapeseed cultivars (brassica napus l.), two field experiments were carried out as split plot arrangement in complete block design with four replications. this research was performed in agricultural experimental station of agricultural and natural resources research center of markazi...

this study was conducted to evaluate the effect of sowing date on morphology, yield parameters, as well as oil percentage and fatty acids composition of castor bean. the experiment was carried out at research farm of tarbiatmodaresuniversity, in randomized complete blocks design with three replications during 2010. plants were grown at six sowing dates of 5th april, 20th april, 5th may, 20th ma...

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...

Two sesame cultivars (Sesamum indicum L.) were evaluated using various 3 different sowing dates (20 th June, 10 th and 30 th July) and four nitrogen levels (0, 40, 80 and 120 kg N ha -1 ) at the New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during summer 2012. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement using f...

to evaluate the effects of seed priming with salicylic acid on quality and baking traits of wheat flour, cv. alvand, under different sowing dates, a factorial experiment was conducted on the basis of complete randomized block design. the factors were seed priming with salicylic acid (including untreated seeds or control treatment, 400, 800, 1200, 1600, 2000 and 2400 µm concentrations of salicyl...

In this paper, a recommender system based on rough mereology was presented for predicting best cultivation dates for wheat in Egyptian Sinai Peninsula according to the required mean temperature for germination stage during October to December. The weather data was hourly collected from El-Arish weather station in north Sinai government from 1985 to 2013. As far as we know, this was the rst stud...

castor oil due to extraordinary physicochemical properties has numerous applications in pharmaceutical, chemical, hygienic, biodiesel and nowadays in food industries. during plant growth and development, as well as during postharvest and processing, different factors may affect caster oil properties. this study was conducted to evaluate oil content and physiochemical properties under different ...
