In order to develop a cane yield forecasting system using crop In order to develop a sugarcane yield forecasting system, a crop yield simulation model is evaluated at the scale of a mill supply area (MSA), using historical climate and yield data. The area1 extent of this scale necessitates the development of spatially distributed model input, both for historical model evaluation and for future ...

The influence of crop residue amendments on the chemical properties of an acid soil and rice yields was investigated at Abakaliki for two cropping growing seasons (2006 and 2007). The residue treatments were rice straw, burnt rice husk and legume residue, while the rice cultivars were ITA 315, Ex-China and ITA 257. The design of the experiment was a 3 x 4 factorial in a Randomize Complete Block...

Declines in cabbage (Brassica oleracea var. capitata) crop quality may result from delaying harvest to allow for greater total yield. An accurate, reliable, rapid and inexpensive method to estimate yield before harvest not requiring direct weight measurements would assist cabbage growers and handlers in harvest scheduling. Results from 3 years of study during which a tool to predict cabbage yie...

Climate variability adversely impacts crop production and imposes a major constraint on farming planning, mostly under rainfed conditions, across the world. Considering the recent advances in climate science, many studies are trying to provide a reliable basis for climate, and subsequently agricultural production, forecasts. The El Niño-Southern Oscillation phenomenon (ENSO) is one of the princ...

Alternate bearing (AB) is the process in fruit trees by which cycles of heavy yield (ON crop) one year are followed by a light yield (OFF crop) the next. Heavy yield usually reduces flowering intensity the following year. Despite its agricultural importance, how the developing crop influences the following year's return bloom and yield is not fully understood. It might be assumed that an 'AB si...

Meeting the projected global demand for food and fuel from corn systems while conserving natural resources and improving environmental quality can only be achieved by the intensification of existing corn systems. Yield analysis of the central U.S. Corn Belt indicates that there is a large exploitable yield gap for corn. Since 1999, we have been experimenting with optimizing corn management syst...

In this paper, an approach to assessing ecological suitability of crop growth was developed using GIS, through a case study of maize planting in Jilin Province, in the northeast China, in order to improve the accuracy and objectivity of the evaluation, promote the rationality of crop distribution, and increase the efficiency of the agro-resource utility. Climate and soil conditions in the regio...

S table and secure food production is essential to civilization. Any methods that improve our understanding of crop yields have the potential to reduce human suffering and help provide the caloric needs of an expanding world population. Similar hopes apply to commodity crops such as cotton and those used to meet energy needs. Given the vast amount of agricultural research and experience, it mig...

the greatest limitations to agricultural development and production in iran are scarcity of water resources, ineffective irrigation scheduling and wasteful water usage. avenues discussed for optimum water use include improving water productivity by improving irrigation scheduling, farm water management and water profitability. the present study evaluated current water use and ways to improve wi...
