In order to study the effect of different levels of the manure and foliar application of Zn and Mn fertilizers on the quantitative and qualitative yield of soybeans (var. Williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. Treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two lev...

Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...

abstract to evaluate the effects of the irrigation termination in different growth stages on yield and its components of autumn’s canola cultivars in isfahan region. an experiment was conducted in 2005-2006 in kabotar abad research station. a split plot layout within a randomized complete block design with tree replication was used. main plots were seven level of the irrigation cut-off time (d1...

Field experiments were conducted at Ebonyi State University, Faculty of Agriculture Research Farm Abakaliki, Nigeria during 2009/10 growing seasons to evaluate the effects of staking and planting dates on the grain/tuber yields of seven accessions of African yam bean (Sphenostylis stenocarpa, Hochst. Ex. A. Rich). The results indicated that all the African yam bean accessions performed better w...

Average grain yield for the full-season varieties, over all treatment combinations, was 165 bu/acre. This average was impacted primarily by variety differences with ‘Wells’ averaging 180 bu/acre and ‘Cybonnet’ averaging 152 bu/acre. There were no significant differences between rotation, tillage, or fertility main-effect treatments. Summaries of grain yields for the main effect of tillage indic...

Grain legume production in Europe has recently come under scrutiny. Although legume crops are often promoted to provide environmental services, European farmers tend to turn to non-legume crops. It is assumed that high variability in legume yields explains this aversion, but so far this hypothesis has not been tested. Here, we estimate the variability of major grain legume and non-legume yields...

Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...
