Building from the perception that farmers have an intimate knowledge of their local environment, production problems, crop priorities and criteria for evaluation, an on-farm experiment was conducted w...
Fertilizer application is one of the most important operations in agricultural production. Traditionally, fertilizer is applied onto the whole farmland regardless of the variations across the land.
Different methods of application of N and P fertilizer after rainfall were compared with no fertilizer application at the time of wheat sowing (cv. GA-2002). The data regarding flag leaf area, numbe...
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 ...
It was investigated whether the amount of ammonification could be used as an index of soil analysis for fertilizer application, which was related with the amount of soil nitrogen supplied from paddy f...
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 Nitrogen Fertilizer Application and Solar radiation on the Growth Response of Sorghum Seedlings to Soil Moisture.
Effects of fertilizer application levels on peach fruit growth and pit spilitting were investigated using ‘Hakuho’ trees supplied with complete liquid fertilizers containing 80 ppm (normal fertilizati...
The effect of fertilizer application methods on cut flower quality and nutrient uptake of spray chrysanthemums were investigated in bench culture. Plants were fertilized once a week by the following f...
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'...
