The present study was conducted to develop the basal fertilizer application methods which mitigate the damage due to cool weather at booting stage by investigating the relationships between the change...
The Influence of nitrogen release from paddy soils on the grain yield of rice plants was investigated, and the optimum amount of nitrogen fertilizer application was estimated for each of the soil nitr...
Topsoils collected from various regions in Fukuoka Prefecture were incubated and the amount of mineralized nitrogen was measured. The relationship between the mineralized nitrogen amount (N) and the ...
The relationship between quality and mineral contents in grain was investigated with Asakazekomugi and Norin 61 cultivated in 4 soil types: Gray lowland soil, Red soil, Thick High-humic Andosol and ...
Grain and flour of Asakazekomugi and Norin 61 cultivated in Gray lowland soil, Red soil and Thick High-humic Andosol were analyzed for N, P, K, Mg, Ca and Mn contents. Ash content was compared with t...
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'...
In Tomo Area of Gunma prefecture, paddy rice cultivar Goropikari has been widely cultivated since 1993. This cultivar has a good taste, but, farmers pointed out its weak resistance to diseases and ins...
Cultivar evaluation is essential to ascertain the superiority of the newly developed genotypes over the established cultivars in terms of yield and adaptation to an ecology. Field experiments were con...
In direct-sowing rice culture using cloth mulch, puddling and leveling (P & L) is usually done 2 days before the mulching (sowing). However, the mulching is very difficult, due to the muddy condition ...
The results of the experiment revealed that N, P, K and S uptake increased with increase in plant population from 3.33 to 5.0 lakh plants ha-1 in all the three seasons. Among the nutrient management p...
