A common crop rotation in the west Iran is wheat-fallow-corn. The fallow period after wheat harvest (during fall and winter) can lead to soil erosion, nutrient losses (e.g. nitrate leaching) and offsi...
The grain yield and grain protein content of winter triticale in dry farming can be significantly affected by environmental conditions and different nitrogen (N) levels. Two year field trials with six...
Labor-saving for fertilization has been strongly desired due to the shortage in labor and increasing scale of farming for rice cultivation. In order to clear these problems, the effect of application ...
This study was carried out to clarify the effect of controlled rhizophere sizes on various characteristics of each organ at the heading and maturing stage in paddy rice plants (Oryza sativa L., cv. N...
A glasshouse pot sand culture experiment was conducted to determine the effects of three levels of combined nitrogen-0N (0), 1N (100), 2N (200 pm) -on nitrogen nutrition, seed protein and oil content ...
The effect of nitrogen fertilizer on biomass production, nodulation, seed yield and CO2 exchange was determined in soybean (Glycine max Merr. cv. Akiyoshi) grown in a pot sand culture in a glasshouse....
The effects of the amount of nitrogen fertilizer on the starch metabolism of rice leaf sheath during the heading period in the japonica rice variety, cv. Nipponbare were compared with those in the ind...
Environmental resources for rainfed rice production show large variability even within a small area in Northeast Thailand, and it is said that farmer’s management is well adapted to the variability. T...
This study was carried out to establish cultivation techniques that improve the eating-quality of rice grown in Andosol (AL) paddy fields by the modification of nitrogen fertilizer application and the...
The effects of shading and nitrogen (N) fertilizer levels on the turning point of the leaf emergence rate (TPLER), and the leaf emergence rate and tillering of rice plants before and after TPLER were ...
Effects of applying soil amendments and the rate of nitrogen fertilizer application on tree and fine root growth and fruit quality were surveyed in ‘Shiranuhi’ 〔‘Kiyomi’ (Citrus unshiu Marc. × C. sine...
Winter wheat usually seeded in autumn was seeded before continuous snow cover and the most appropriate method of nitrogen (N) fertilization was examined using variety “Nanbukomugi”. In the plants supp...
The efficiency of nitrogen fertilization (the increase of grain yield (G) per unit nitrogen fertilizer (FN) applied at the regrowing stage, ΔG/ΔFN) of high yielding winter triticale cultivar 'Presto'...
The use of legume crops in maize rotation systems may decrease the need for nitrogen (N) fertilization and increase total output. The effect of previous crops (wheat, barley, lentil, Hungarian vetch, ...
The physiological mechanism of photosynthetic function and senescence of rice leaves was studied by using early rice variety Baliangyou 100 and late rice variety Weiyou 46, treated with controlled-rel...
