Small farms and smallholder farming systems play crucial roles in agricultural development in many developing countries. From the various rural development programs designed to support such farming systems, agricultural extension services are of at most importance. However, the benefit that farmers obtain from these services and the resulting impact depends, to a great extent, by their direct a...

Kenya’s fast growing human population is expected to reach 35 million by the year 2000. In order to cope with such a rapid rate of growth, efforts must be directed towards adequate agricultural and livestock production to counter the disproportionate increase in demand for food. To provide sufficient animal protein (milk and beef products) attempts must be made to eliminate the current constrai...

Frontiers in Livestock Genomics (FLG) provides a venue for investigators to publish basic, applied, and methodological research toward a better understanding of the genetic mechanisms underlying the expression of complex phenotypes in livestock, the effects of domestication and evolutionary processes on genome variability, as well as innovative strategies for the genetic improvement of economic...

Riparian meadows occupy a small proportion of the public lands in the western United States but they provide numerous ecosystem services, including the production of high-quality forage for livestock grazing. Modern conservation management strategies (e.g., reductions in livestock stocking rates and adoption of new riparian grazing standards) have been implemented to better balance riparian con...

To fulfill the United Nation's Sustainable Development Goals (SDGs), it is useful to understand whether and how specific agricultural interventions improve human health, educational opportunity, and food security. In sub-Saharan Africa, 75% of the population is engaged in small-scale farming, and 80% of these households keep livestock, which represent a critical asset and provide protection aga...

Agricultural extension workers’ service has been placed as the central pattern of agricultural transformation in general and smallholder farmers in particular. Due largely to this commensurately known trend, identifying factors that determine farmers’ access to extension workers’ service and the effect of the service on crop yield was found to be imperative. Cross sectional data was collected t...

Fecal contamination and organic pollution of an agricultural drainage in northeast Indiana was high. Bacterial counts (total coliform, TC; fecal coliform, FC; and fecal streptococcus, FS) and biochemical oxygen demand (BOD) were used to assess waste concentrations. Coliform counts indicated that sections of the drainage receiving septic effluent had waste concentrations far in excess of public ...

SIDR had great impact on crop, livestock and fisheries at Pirojpur district in Barisal Division. To perform this study data were collected from the three selected village (south Shailkati, Hothkhali and Lahori) affected people by random sampling after selecting the study topic and area. SIDR also created a great impact on the production of different types of crop. Rice production was reduced to...

Surplus nitrogen (N) in ground and surface water is of concern in intensive agricultural regions. Surplus N leaches during lengthy periods where annual crop systems are used in temperate regions. This paper presents a model to estimate the surplus N available for leaching to ground water beneath agricultural systems and applies the model to watersheds in an intensive maize and soybean productio...
