Effect of sowing time and nitrogen fertilizer rates on growth, seed yield and nitrogen use efficiency of quinoa (Chenopodium quinoa Willd) in Ahvaz, Iran
To study the effect of sowing time and nitrogen levels on growth, yield and nitrogen efficiency of quinoa cv. Titicaca, a field experiment was conducted at in 2017-2018 growing season research farm of Agricultural and Natural Resources Sciences University of Khuzestan, Ahvaz, Iran. The experiment was conducted in split plot arrangement in randomized complete block design with four replications....
متن کاملتاثیر سولفات آمونیوم بر رشد و تجمع یونی در دانهال های نارنج (Citrus aurantium) تحت شرایط تنش شوری
In order to investigate the interaction effect of salinity and nitrogen on growth, mineral composition and salinity tolerance of soure orange seedlings a factorial experiment was carried out in completely randomized design with three replications. Factors consisted of four sodium chloride rates (0, 250, 500 and 1000 mg sodium chloride kg-1 soil) and four nitrogen levels (0, 50, 100, and 200 mg ...
متن کاملYield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation
Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...
متن کاملتأثیر کود نیتروژنه و فسفره بر تولید گیاهان مرتعی در ایستگاه تحقیقات مرتع سمیرم
The effect of nitrogen and phosphorous fertilization on range species production was studied using factor combination method as factorial with 3 blocks and 12 treatments. Nitrogen in 4 levels of 0،25،50 and 75 kg N/ha and phosphorus in 3 rates of 0،30 and 60 kg N/ha were used. Results indicated no significant difference between nitrogen rates in different growth forms of grass, bush and Eurotia...
