• As we know, the inflorescences that will produce any year’s grape crop start differentiating inside the buds in the previous year. There are 2 main stages of development: formation of primary branches starts in Year 1, before the vine goes dormant; secondary and tertiary branching, as well as individual flower differentiation, continues around budbreak of Year 2. Thus, the cropping potential ...
A Louisiana sugarcane field is typically replanted every four years due to declining yields, and, although, it is a costly process, it is both necessary and an opportunity to maximize the financial return during the next four year cropping cycle. Fallow planting systems (FPS) during the fallow period prior to replanting sugarcane have the potential to influence not only the following sugarcane ...
Crop sequence patterns are considered as those schemes farmers apply within a single field to succeed crops over time, regardless of whether the same crop is grown continuously or a diverse rotation is used. This study aimed at identifying these patterns for a large and representative area in Northern Germany during a six-year period from 2005 to 2010. The analysis was carried out for the entir...
The utilization of NOAA-AVHRR NDVI data for crop yield forecasting is of particular importance in semiarid regions where there are strong inter-year yield fluctuations due to meteorological vagaries. The present work deals with the use of monthly GAC NDVI data for the early estimation of cereal crop yield in Mediterranean African countries. A preliminary analysis showed that relatively high cor...
Submit Manuscript | http://medcraveonline.com in its theoretical yield (470mt ha-1 year-1) and productivity achieved at field (168 mt ha-1year-1) with average cane yield hovering around 65 tonnes ha-1. In India, which is second largest sugarcane producer in the world after Brazil, this productivity lingers around 28 % of the theoretical maximum. The prevalence of short duration crop cultivation...
Crop decision planning is an important part of effective farm management. Because of the many uncertain factors such as weather variations, technology advances, and crop yields and prices, all of which prove to change considerably, decision planning can be very complex. The focus of this paper is to develop accurate yield and price forecasting models to aid in decision planning. For yield forec...
Most studies of the influence of weather and climate on food production have examined the influence on crop yields. However, climate influences all components of crop production, includes cropping area (area planted or harvested) and cropping intensity (number of crops grown within a year). Although yield increases have predominantly contributed to increased crop production over the recent deca...
An obvious need for an updated and comprehensive study prompted this investigation of the complex of environmental costs resulting from the nation’s dependence on pesticides. Included in this assessment of an estimated $10 billion in environmental and societal damages are analyses of: pesticide impacts on public health; livestock and livestock product losses; increased control expenses resultin...
We examined the effects of the sowing time on the yield production and oil content of the sunflower hybrids in 2010 and 2012. The crop year and the sowing time had both a strong impact on the yield, on the oilcontent and yield. By delaying the sowing time both the yield crop result and the oil yield increased. In 2010 in terms of crop yield and oil yield results PR64H42 was the best, in 2012 NK...
Agronomic research suggests Australian farmers may increase wheat yields by 13 to 47% and reduce risk of crop failures by sowing crops earlier than is currently practiced. This study investigated the potential to use remote sensing to assist in evaluating changes in farmer sowing date practices in response to research recommendations, using study paddocks in the southern Australian cropping reg...
