The National Agricultural Statistical Service (NASS) of the U.S. Department of Agriculture conducts field interviews with sampled farm operators and obtains crop cuttings to make crop yield estimates at regional and state levels. NASS needs supplemental sp...

Implementing strategic tillage (ST) in otherwise long-term no-till (NT) systems could control herbicide resistant weeds and increase profitability of crop production semi-arid dryland cropping systems. For the purpose this study, ST is defined as a single event (once every 6-10 years) an NT system to reduce density tolerant grass weeds. However, there little information on (>5 effects soil heal...
by application of climatic zoning methods, it is possible to study different agricultural aspects and then with harmony this aspects, determined similar states in a zone. today, simulation models are widely used around the world in agricultural research and education and cropland management. due to the vast extent of the agricultural activities in iran, application of such models seems to be qu...
Crop productivity is improved by ecosystem services, including pollination, but this should be set in the context of trade-offs among multiple management practices. We investigated the impact of pollination services on coffee production, considering variation in fertilization, irrigation, shade cover, and environmental variables such as rainfall (which stimulates coffee flowering across all pla...
