the agricultural regions are running into difficulties, which are restrictive availability of water, successive appearing draughts, and overuse of ground water resources for supplemental water requirements. as a sample which is got from the farm is sent to the laboratory for testing and the laboratory works need devices. hence, conducting farm experiments are expensive and time consuming to opt...

یکی از چالش های موجود در بخش کشاورزی مناطق خشک ازجمله ایران افزایش دادن تولیدمحصول به ازاء واحد حجم آب مصرفی است. کم آبیاری یکی از استراتژی های افزایش کارآیی مصرف می باشد. موفقیت استراتژی کم آبیاری تا حدود زیادی بستگی به شناسایی عوامل تأثیرگذار در رشد و نمو و نحوه پاسخ گیاه هدف به این عوامل دارد. کاربرد توابع ریاضی و مدل های شبیه سازی رشد گیاهان کمک زیادی برای نیل به این هدف می کنند. در این مطا...

The Aqua-Crop simulation model has been playing a crucial role in assessing the performance of existing strategies for management irrigation schemes improving agricultural water use efficiency. This study evaluated using Onion crops under deficit and mulch practices semi-arid Nigeria. Measurements were taken from experimental plots which consisted each at 4 levels used to evaluate canopy cover,...

To get representative soil samples, a sampling method was verified for crop fields in the vicinity of abandoned mine sites. Application of appropriate sampling or analytical methods is very important as it affects the costs, time, and accuracy of the refined investigation of soil contamination. Two-time sampling for each crop field was conducted to verify the reproducibility of a zigzag method ...
