Land-use and agricultural practices affect the soil microbial carbon (C) and nitrogen (N) turnover and hence the biosphere-atmosphere exchange of greenhouse gasses (GHG), namely N2O, CH4 and CO2. In view of the global importance of irrigated agriculture, it is crucial to understand how and to which extent this land-use system interferes with the terrestrial N and C cycles and contributes to the...

The harvest index of grain can be used as indicator for the potential yield crop. aim this study was to determine variation wheat and triticale differences in monocrops intercrops systems cultivation under different field environmental conditions. experiment, carried out conditions two consecutive years, designed according a randomized block system so that each species sown single crop combined...

It is well known that legume–cereal intercropping systems are more efficient in terms of resources use, particular nitrogen (N) and water. However, the response this cropping system to water N co-limitation was poorly studied most recent field researches. The present study aims assess relationship between use efficiency (NUE WUE) by chickpea–durum wheat under contrasted climate supply condition...

Agroforestry has been widely practiced in the Loess Plateau region of China because of its prominent effects in reducing soil and water losses, improving land-use efficiency and increasing economic returns. However, the agroforestry practices may lead to competition between crops and trees for underground soil moisture and nutrients, and the trees on the canopy layer may also lead to shortage o...

Research project entitled “Yield and economic dynamics of intercropping in summer vegetables ” was conducted at Horticultural Research Farm, NWFP Agricultural University, Peshawar (Pakistan) during 1999 and 2000. Summer vegetables were evaluated alone and in various combinations for their yield, land equivalent ratio and income in intercrop combinations. Each plot was 4x4 m whereas number of ro...

Intercropping, which is the agricultural practice of growing two or more crops in the same land area, is not currently yielding adequate results in Africa. Despite the advantages of intercropping like improved soil fertility, protection against pests and diseases and eventual increase in farm yield, this farming practice is faced with challenges—inadequate planning, bad crop management and lack...

Concern about NO− 3 leaching and groundwater pollution from corn monoculture has prompted an investigation of alternative production systems that reduce leaching. It is hypothesized that both intercropping and water-table control could increase N uptake and reduce the quantity of N that might be lost due to leaching. This study compared corn (Zea mays L.) with annual Italian rye-grass (Lolium m...

Soil sickness is a critical problem for eggplant (Solanum melongena L.) under continuous cropping that affects sustainable eggplant production. Relay intercropping is a significant technique on promoting soil quality, improving eco-environment, and raising output. Field experiments were conducted from September 2010 to November 2012 in northwest China to determine the effects of relay intercrop...

Inverse linear relationships between soil strength and yield in Coastal Plain soils that have subsurface genetic hard layers have previously been developed for corn (Zea mays L.), soybean (Glycine max L. Merr.), and wheat (Triticum aestivum L.) grown under management systems that include annual or biannual non-inversion deep tillage. In a field study in the southeastern Coastal Plains of the US...
