smallholder schemes will not survive Irrigation Management Transfer (IMT) as it is currently envisioned. For IMT to be successful in the African smallholder context, governments must first enhance the income-creation potential of smallholder irrigated farming by strengthening market access, promoting high-value crops and improving extension and technical support to smallholder irrigators. This ...

Soil organic matters are considered as the animal and plant residues and active components of soils. The cultivation practices will cause the quick removal of organic matters in soils even in those which are not affected by erosion. This study was carried out to assess the level of soil humus in the pilot area, to investigate the positive or negative effect of humus level on soil and to introdu...

assessment of soil quality is one of the most useful tools for evaluation the soil management condition and different land uses. quantity indices of soil quality are most suitable methods for determination and comparison of soils quality. in this study soil quality indices and selection methods of effective soil properties were compared for evaluating the soil quality in different land uses. se...

in asia, food security and poverty alleviation depends on sustainable rice production. the study examined factors determining irrigated and rainfed rice farming sustainability in bangladesh. data for the study were collected through a farm households survey, covering 390 rice growers (sample size was determined by using the sloven’s formula), and also via observation, key informant interview, a...

Cropcheck developed following the identification of limitations to the Transfer of Technology (TOT) extension model which occurred through the 1970’s and into the early 1980’s (Lacy 2011). Irrigated wheat yields stagnated with high variability from year to year and no understanding as to why this occurred. This was despite several communication methods (farm visits, demonstrations, plot trials,...

Water and phosphorus (P) are two critical resources for high nature value farming in semi-dry mountains. ey are major drivers of grassland productivity but can negatively a€ect plant diversity. Soil moisture is known to a€ect soil microbial activity and plant P nutrition but the e€ects of irrigation on soil P status, soil microbial P and plant P nutrition in semi-natural grasslands remain larg...

A multiperiod model based upon a multicriteria objective function has been developed for a representative area of the Guadalquivir Valley, dividing the irrigated area into homogeneous types of farming as identified by cluster analysis. The model was applied to different future scenarios with a time horizon of 10 years and several different farming environments. A set of eight sustainability ind...

the present study was conducted to investigate qualitative and quantitative aspects of irrigated wheat production in three major farming systems i.e. peasant, commercial and cooperative systems in kordestan province. accordingly, seven basic hypotheses were tested. the data were drawn from individual interviews with 360 farmers who planted wheat in 2004-2005. the sample was selected using multi...
