Finger millet landraces viz., TZA-01 and TZM-01 were grown in glasshouses under two moisture regimes (fully irrigated and after drought) to investigate the effects of environmental stress on the growth, SPAD measurement, radiation use efficiency and yield of finger millet (Eleucine coracana). The drought treatment was imposed at 28 DAS beyond which no irrigation was applied to the droughted tre...
In order to investigate the effects of moisture stress, nitrogen fertilizer, manure and integrated nitrogen and manure fertilizer on yield, yield components and water use efficiency of SC 704 corn (late maturing, non-prolific and dent). In 2005, a field study was conducted in agricultural experiment station of the college of agriculture, Tarbiat Modares University. The type of design was random...

as one of the most important products of iran, pistachio has a significant share in non-oil revenues. its annual foreign exchange earnings are over 800 million dollars. however, production of this nut in the country’s major production centers is faced with many problems regarding the efficiency and productivity of the inputs. this study was performed by using two-stage cluster sampling method. ...
A study was conducted in 2009/2010 cropping season in order to determine energy input/out put and productivity of potato and sugar beet production systems in Isfahan province, Central Iran. The data used in this study was based on data collected from growers by using a face to face survey. Total energy consumption and total out put enegy in potato production systems were calculated to be about ...
In order to investigate the effect of urea and Azocompost on economic yield, nitrogen use efficiency (NUE) and radiation use efficiency (RUE) of wild majoram, a factorial experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 k...

نیرومحرکه فرسایش آبی نیروی برشی حاصل از سقوط قطرات آب باران میباشد که تحت عنوان عامل فرسایندگی باران در معادله جهانی فرسایش خاک (usle) نیز مطرح میباشد. ازاین رو آگاهی از میزان و الگوی تغییرات مکانی آن برای بهبود مدیریت سرزمین و ارزیابی ریسک فرسایش خاک در شرایط آینده کاربری اراضی و تغییر اقلیم بسیار مهم و حیاتی است. هدف از این تحقیق بررسی الگوی تغییرات فضایی عامل فرسایندگی باران با استفاده از ...
to study the effects of simultaneous application of urea, znso4 and inoculants, (azotobacter and azospirillum), on uptake and nitrogen use efficiency in rapeseed, var. hyola308, a field experiment with split plot factorial layout based on a randomized complete block design was conducted at the research field of faculty of agricultural science, university of guilan in 2008. experimental treatmen...
The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...
