Aims: It is utmost desire for plant breeders to know the extent of relationship between yield and its various components, which will inevitably facilitate selection of desirable characteristics. This research focused on computing the correlation coefficients and path coefficients...
This study analyzed the loan demand requirements of rural staple and poultry farmers in Owerri Agricultural Zone of Imo State, Nigeria. Also, the factors affecting loan size were analyzed. In carrying out this cross-sectional study, data were collected with stratified sampling te...
Thirteen rice varieties cultivated in Sierra Leone were used to examine varietal differences in radiosensitivity to gamma radiation during the wet season of 2006 in the lowland ecology. Dry seeds of rice varieties were exposed to gamma radiation ranging from 50 to 800 Gy to deter...
Aims: The paper examines the economic linkages between rural farm and rural non-farm sectors in Alabama. Because growing land scarcity and land conversation pressure from urban development raises concerns about prospects for rural labor absorption, the paper highlights the impact...
Cotton (Gossypium hirsutum L.) grown in the Mississippi River Delta is generally planted in cool conditions that can lead to slow germination, uneven emergence, and poor root growth. A study was conducted to determine the effects of low temperature on four genetic and geographica...
