The study analyzed factors that influence farmer’s participation in hybrid maize seed production in the study area. A Logit analysis was used to analyze factors influencing farmer’s participation in hybrid maize seed production while T-test was used to analyze if there is difference in the mean yields of farmers growing hybrid seeds and those involved in local maize production. Structured quest...

Intercropping induces the diseases decreasing, and yield increasing, may partly due to the improvement of microclimate in fields. In order to understand the mechanism and efficiency of resource utilization in intercropping of maize (Zea mays) and soybean (Glycine max), a field experiment was conducted as factorial on the bases of randomized complete block design of three patterns with three rep...

The study assessed economic of maize production in Ogori/Magongo local government area of Kogi State. To this end, effort was made to examine the socio economic characteristics of the maize farmers, determine the resource use efficiency, problems as well as profitability of maize production in the area. To achieve the objectives of this study 48 maize farmers where randomly selected from 5 ward...

In Europe, the framework for sugar beet (Beta vulgaris L.) production was subject to considerable changes and for the future it is expected that sugar beet cultivation might concentrate around the sugar factories for economic reasons. Based on data from a national sugar beet farmers' survey and multi-year crop rotation trials, the effects of cropping interval (number of years in between two sub...

Soil organic carbon (SOC) dynamics in agro-ecosystem is largely influenced by cropping. However, quantifying the contributions of various crops has been lacking. Here we employed a stable isotopic approach to evaluate the contributions of wheat and maize residues to SOC at three long-term experimental sites in north China. Soil samples were collected from 0-20, 20-40, 40-60, 60-80 and 80-100 cm...

Experiments comparing conventional and organic systems often report similar yields despite substantially higher weed abundance in the organic systems. A potential explanation for this observation is that weed– crop competition relationships differ between the two types of systems. We analysed weed and crop yield data from the Rodale Institute Farming Systems Trial (FST), which provides a unique...

Fresh water scarcity has become a global problem which needs a serious attempt to find proper solutions for decreasing the pressure on the limited water resources. The exact estimation of crop virtual water would help with choosing crops with high crop and water productivity which lead to both food and water security. Thus, in this research, maize virtual water was estimated using HYDRUS2D base...

to study the effect of planting rates and harvest time on forage quality of maize in maize-cowpea intercropping, an experiment was conducted at the research farm of zabol university, during 2007 and 2008. the experiment was arranged in a 7×2 factorial one in complete randomized block design with 4 replications. the two factors consisted of seven planting ratios of maize and cowpea (100:100, 100...

This study was conducted to determine the potential evapotranspiration (PET) of maize, the crop coefficient (Kc) under full water requirement as well as the cause of decrease in maize yield. It was determined that the seasonal PET of maize is about 486.6 mm. The Kc under full water supply was found to be: 0.11, 0.35, 1.51 and 0.34 for initial, development, midseason and the late season stages r...

Most soil studies aim a better characterization of the system through indicators. In the present study nematofauna and soil structure were chosen as indicators to be assess soil health as related to agricultural practices. The field research was carried out on the two fodder cropping systems continuous maize (CM, Zea mays L.) and a 3-year rotation of silage-maize – silage-barley (Hordeum vulgar...
