In order to investigate crop coefficient (Kc) and evapotranspiration (ET) of grain maize modified by planting density, a field experiment was conducted from March to October in 2012 and 2013 in an arid region of northwest China. Five planting densities, i.e. 67,500, 82,500, 97,500, 112,500 and...

Getting maximum benefits from cereals do not lie in reducing N-rate and its number of splits but lowering cost per unit cereal production through higher yields. Field experiments were conducted on maize (Zea mays L.) at the New Developmental research Farm of NWFP (Northwest Frontier Province)...

The study investigates the economic response of tart cherry yields to planting density using an unbalanced longitudinal yield data from tart cherry orchards in Northwest Michigan. The relationship between tart cherry yield and tree age is specified as a linear spline function and planting...

Increasing scarcity of water for irrigation is one of the major challenges for forage producers in all arid and semi-arid regions. Selecting drought tolerant forage species such as sorghum (Sorghum spp. L.) over corn, as a common forage crop, could be a viable option to cope with the limited...

Planting density is of great significance in adjusting the population structure of rice, increasing yield and reducing the cost. And suitable planting density can not only bring the yield potential of rice population into full play, obtain the maximum grain yield per unit area, but save labor,...

Market pressure is forcing New Zealand greenhouse tomato growers to shift from conventional to more environmentally-friendly pest control methods such as IPM (Integrated Pest Management). Growers can access IPM manuals, but these tend to provide generalized advice, which they find difficult to...

The U.S. fresh winter tomato industry and Mexican tomato production have been engaged in a trade conflict since the early1970s. Given that tomato is the highest valued fresh vegetable item, the fresh tomato market in the U.S. is open for rent seeking actions of importers and domestic producers....

This study examines energy use patterns and the relationship between energy inputs and yield for greenhouse tomato production in Antalya province of Turkey. The data used in this study were based on cross-sectional data collected from growers by using a face to face survey. The results revealed...
