Accurate information of crop rotation in large basin is essential for policy decisions on land, water and nutrient resources around the world. Crop area estimation using low spatial resolution remote ...
Effects of crop rotation on soybean (Glycine max (L) Merr.) seed composition have not been well investigated. Therefore, the objective of this study was to investigate the effects of soybean-corn (Zea...
Arbuscular mycorrhizal fungi (AMF) improve the uptake of immobile mineral nutrients such as phosphate, thereby improving plant growth. In acid sulfate soil (ASS), AMF spore density is generally low wh...
Two crop rotation cycles were evaluated to determine the effect of cropping systems and N fertilization on the yield and efficiency of N in maize. Maize was grown on plots which had previously support...
To elucidate the effect of no-tillage practice on the root system development and productivity in a wheat-soybean rotation system in Japan, we continuously cultivated these crops under tilled and non-...
Water-saving rice-winter crop rotation systems were repeated for 4 cycles from 2000 to 2004 in an urban area, Nishitokyo, Japan, to assess the effects of water-saving (i.e. non-flooded vs. flooded) on...
We introduced subsoiling to a field of wheat-soybean rotation where no-tillage practice had been conducted for five years and whose yield tended to decrease or stagnate. By subsoiling a half of each p...
Effects of sowing time and planting density on the protein content of the seeds collected from main stems and branches were investigated to establish the cultivation technique for improving the prot...
Recently, damages by soybean cyst nematode (SCN) are increasing in Japan, due to continuous cultivation of soybean, and the establishment of the culture method to control SCN is awaited. In this rese...
A three year (20052008) field experiment was conducted in Central Lithuania to study the effects of different crop rotations (spring oil-seed rape-spring barley-winter wheat; winter wheat-spring rap...
The research was carried out over 2004-2006 at the Experiment Station Osiny (51°28’ N; 22°04’ E) of the Institute of Soil Science and Plant Cultivation – PIB in Puławy. Three technologies of cult...
Assessment of weed infestation in winter wheat, winter triticale and spring barley cultivated since year 1998 in cereal crop rotation under three technologies varying in production intensity was cond...
The study aim was the assessment of energy efficiency in the two-course rotation: fallow – winter wheat. The assessment was made on the grounds of a field experiment conducted at the Experimental Stat...
The present research covers the time of the second rotation: sugar beet-spring wheat-pea-winter triticale (1999-2002). The investigations were conducted on a very good rye complex soil. A reduced till...
The aim of the present studies carried out over 1994-1998 was to define the effect of multi-year fertilisation with straw + NPK, NPK only, manure only, manure with: PK, NK, NP, NPK, NPK + Ca and no fe...
