Information on the effect of planting date and irrigation on soybean [Glycine max (L.) Merr.] seed composition in the Early Soybean Production System (ESPS) is deficient, and what is available is inconclusive. The objective of this research was to investigate the effects of planting date on seed protein, oil, fatty acids, sugars, and minerals in soybean grown under irrigated (I) and non-irrigat...
Under irrigation and in double-cropping system, a large amount of plant residue remains after harvest that along with the limited time for residue decomposition and complete seedbed preparation, necessitates reduced tillage and special residue management. In the present study, the effects of various seedbed preparation methods on vegetative growth, yield components and seed and oil yields of su...
intercropping is considered for increasing and stability of yield in per unit. in order to evaluating the effect of corn/soybean intercrop in different planting dates, a study was carried out in agricultural sciences and natural resources, university of sari, faculty of agriculture during 2005-2006. the experiment was a split plot design based on randomized complete block design with four repli...
Camelina is one of the plants that it seed yield is highly dependent on planting date. This experiment was conducted using randomized complete blocks design with three replications in research farm of Fasa Branch, Islamic Azad University, Fasa, Iran in 2018 and 2019 cropping seasons. Planting dates at six levels; November 1, 11, 21 (autumn sowing) and February 20, March 1 and 11 (winter sowing)...
The basic requirements for small scale cropping machines are, they should be suitable for small farms, simple in design and technology and versatile for use in different farm operations. A manually operated template row planter was designed and developed to improve planting efficiency and reduce drudgery involved in manual planting method. Seed planting is also possible for different size of se...
In order to investigate the effect of bio-fertilizers on the effective physiological characteristics and to improve the performance of common bean (Phaseolus vulgaris L.) and black cumin (Nigella sativa L.) in different ratios of intercropping, a field experiment was conducted as a factorial based on a randomized complete block design with three replications; this study was carried out at the r...

During recent years, several genotypes have been selected from Isfahan land race Kouseh. The performance of safflower selected genotypes was studied in the field conditions, at Agriculture Research Station, Isfahan University of Technology during 2003. The experiment was carried out using a split plot arrangement according to a randomized complete block design with three replications. Planting ...

روانگرایی در ماسه های ریزدانه اشباع در هنگام زلزله، موجب خرابی سازه های زیادی در نقاط مختلف دنیا بوده است. از عوامل موثر در این پدیده می توان به تراکم خاک، دانه بندی خاک، عمق لایه مورد نظر و تنش های موثر همه جانبه، شدت و مدت زمان زمین لرزه و درصد عبوری از الک شماره 200 (مقدار ریزدانه و جنس آن) اشاره نمود. عالباً در روشهای رایج ارزیابی وقوع روانگرایی از خصوصیات درجای خاک، همانند نتایج آزمایش های ...
