Taro [Colocasia esculenta (L.) Schott] is an underutilised crop in sub-Saharan Africa due to lack of agronomic research on it. There is no information describing water-use and drought tolerance of local taro landraces. Therefore, the objective of this study was to evaluate growth, yield and...

Rain-fed maize production in semi-arid areas of the Loess Plateau in China is constrained by low temperatures and water limitations during the early growth stage. Traditionally, gravel mulching was an effective strategy to increase soil temperature and moisture and, therefore, crop production;...

In this study, the cost of groundwater extraction, impact of groundwater depletion on farm income, wateruse efficiency, technical efficiency in crop production and costs of groundwater depletion among different categories of farmers have been reported. The study has been conducted in the...

While no-till (NT) cropping systems can provide conservation benefits in the northern Corn Belt, adoption has been low due to concerns about potential yield reductions and economic risk. Strip-tillage (ST) systems have been proposed as an alternative that may provide many of the conservation...

Irrigation of farmland is a popular agricultural practice in semi-arid areas in China. However, little is known about the impacts of different irrigation strategies on grain yield and soil microbial communities, particularly economically-important arbuscular mycorrhizal (AM) fungi. The aim of...

A study was carried out in the Teaching and Research Farm of Delta State University, Asaba Campus from August to December in 2005 and repeated between March and July, 2006 to evaluate the response of maize (Zea mays) to liquid organic fertilizer. The study was conducted using a split plot fitted...

The aim of this study was to evaluate the potential of the Decision Support System for Agrotechnology Transfer – Cropping System Model (DSSAT-CSM) using the CENTURY-based soil module to simulate long-term trends of grain yield, soil organic C (SOC) and soil organic N (SON) based upon 14-year...

Stable straw and grain yield constituted a challenging objective for breeders to cope with environmental changes as salinity increase. For this purpose, an assessment of grain yield (GY) and yield components stability of 25 durum wheat genotypes was conducted in three semi-arid sites differing...

Model WSM (Wheat Simulation Model) was developed based on the previous model (MSM, Maize Simulation Model). The planted cultivar was Shiraz with five irrigation treatments (1.2, 1.0, 0.8, and 0.5 ratios of the potential irrigation requirement under surface irrigation system and rain-fed) and...
