Potato productivity in the northeastern US has been relatively constant for over 50 years, raising questions about what factors are limiting productivity. Research was initiated in 2004 to identify key constraints to potato productivity by evaluating Status Quo (SQ), Soil Conserving (SC), and Soil Improving (SI) cropping systems under both rainfed and irrigated management, and it was found that...

In agriculture sector where farmers and agribusinesses have to make innumerable decisions every day intricate complexities involves the various factors influencing them. An essential issue for agricultural planning intention is accurate yield estimation numerous crops involved in planning. Data mining techniques are necessary approach accomplishing practical effective solutions this problem. Ag...

An important step in farm planning is the development of a gross margin budget. A gross margin is calculated from a crop's gross income less the variable costs incurred in growing and marketing that crop. The gross margin indicates the potential financial gain or loss of the crop being produced. Gross margins are usually expressed in units related to resources such as land, labour or irrigation...

Elderberry is an alternative crop that holds promise for further commercial development in Florida. This 7-page fact sheet written by Kevin Athearn, David Jarnagin, Ali Sarkhosh, Juanita Popenoe, and Steven Sargent published the UF/IFAS Food Resource Economics Department reviews information on markets elderberries elderflowers estimates establishment costs potential returns a 3-acre elderberry ...

The present study dealt with the real-world problem of irrigation water management of evolving suitable cropping pattern, which should be in harmony with optimal operation of the multi-reservoir system in the basin. The Narmada river basin system, comprising 11 reservoirs either existing, planned or under construction, has been ®rst simulated and analyzed. The time horizon used to simulate the ...

The aim of this study was to predict crop growth of year-round cut chrysanthemum (Chrysanthemum morifolium Ramat.) based on an empirical model of potential crop growth rate as a function of daily incident photosynthetically active radiation (PAR, MJ m-2 d-1), using generalized estimated parameters of the expolinear growth equation. For development of the model, chrysanthemum crops were grown in...

From the early days of remote sensing until today, there has been a wide range of applications of remote sensing data for agricultural management. Improvements in spatial, spectral and temporal resolution of available data products together with precision agriculture have resulted in an increase in the availability of services and products that help to manage agricultural operation more efficie...

crop productivity, water use efficiency (wue), and microbial biomass c and n in rainfed dry area are influenced by tillage, rotation, and crop residue management. field experiments were conducted during 2005-08 to study the effect of tillage, crop rotation, and crop residue retention on oat fodder yield, water use efficiency, and microbial biomass c (mbc) and n (mbn) under semi-arid conditions ...
