soil or water salinity is one of the major problems of agriculture in the arid and semiarid regions of the world, especially in iran. beside the salinity, reasonable canola production depends on nutrient supply so that increase in quantitative and qualitative yield is highly correlated with nutrients availability, especially nitrogen and zinc. in order to investigate the effects of the nitrogen...
Soil salinity may cause nutrients imbalance in plants. Addition of some nutrients to saline soils may alleviate negative effects of salinity on plant growth and yield. In order to evaluate the effect of salinity and phosphorus on growth and chemical composition of two varieties of spinach (Khardar and Virofly Duch) a greenhouse experiment was carried out in a factorial arrangement 2×3×2 in a co...
Increasing fertilizer consumption has led to low fertilizer use efficiency and environmental problems. Identifying nutrient-efficient genes will facilitate the breeding of crops with improved fertilizer use efficiency. This research performed a genome-wide sequence analysis of the A (NFYA), B (NFYB), and C (NFYC) subunits of Nuclear Factor Y (NF-Y) in wheat (Triticum aestivum) and further inves...
Drought is a serious environmental stress limiting growth and productivity in peanut and other crops. Nutrient uptake of peanut is reduced under drought condition, which reduces yield. The objectives of this study were to investigate nutrient uptake of peanut genotypes in response to drought and to estimate the relationship between nutrient uptake and peanut yield under different water regi...
The major source of nitrogen for rice (Oryza sativa L.) is ammonium (NH4(+)). The NH4(+) uptake of roots is mainly governed by membrane transporters, with OsAMT1;1 being a prominent member of the OsAMT1 gene family that is known to be involved in NH4(+) transport in rice plants. However, little is known about its involvement in NH4(+) uptake in rice roots and subsequent effects on NH4(+) assimi...
We try to elucidate which environmental and soil factors control nitrogen uptake efficiency in citrus. Effects of residence time and nitrogen (N) concentration (three 500-mL applications of 7 mg N L(-1), representative of reclaimed water used for citrus irrigation in central Florida, or one 150-mL application of 70 mg N L(-1)) on nitrogen uptake efficiency (NUE) of young citrus seedlings were s...
