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 ...
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...
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...
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 CultivationPIB 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 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...
Harvest residue of spring barley and oats cultivated in two-component mixture and in monoculture in an experiment carried out on medium soil during the years 1998-2000 was examined. The mass of resid...
In 1990-2000 an experiment on average soil investigated the response of cereal mixture of spring barley and oats (50% each) and these cereals separately in pure stand to different crop-rotation posit...
The objective of the study carried out over 1999-2002 on good rye soil complex soil was to evaluate the effect of fertilisation with straw, cultivation of stubble intercrops and the method of placing ...
The present paper covers the results of studies carried out in 1998-2001 on a good rye soil complex at the Mochełek Experiment Station which involved spring barley – winter wheat crop rotation li...
The research was done during 1994-95 and 1995-96 planting season with 3 replications in randomized complete block design, in Antalya to find the possibility of entering crop rotation system for the fo...
