Reduced-tillage, cover crop intensive production systems have several important potential benefits for sweet corn growers including: fuel and labor savings; reduced equipment wear and tear; more timely planting under wet conditions; and improvements in soil physical, chemical and biological properties. Since sweet corn is an important rotational crop for many high value vegetables, improvements...

This article investigates the optimal crop planting schedule and hedging strategy in the mean return versus CVaR risk framework. Crop insurances and futures contracts are available for hedging against yield and price risks. The impact of the ENSO-based climate forecast on the optimal production and hedging decision is examined. Gaussian copula is applied in simulating the scenarios of correlate...

Museum collections constitute a massive store of information on biological diversity. We used museum specimen data to generate ecological niche models that provide predictions of geographic distributions of native rodent pest species and agricultural census data that summarize the geographic distribution of nine crops in the state of Veracruz, Mexico, as well as crop losses between planting and...

Farm managers have to deal with many conflicting objectives when planning which crop to cultivate. Soil characteristics are extremely important when determining yield potential. Fertilization and liming are commonly used to adequate soils to the nutritional requirements of the crops to be cultivated. Planting the crop that will best fit the soil characteristics is an interesting alternative to ...

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...

An understanding of the contribution of manure applications to global atmospheric N2O loading is needed to evaluate agriculture's contribution to the global warming process. Two field experiments were carried out at Dufuya wetland (19°17'S; 29°21'E, 1260 m above sea level) to determine the effects of single and split manure applications on emissions of N2O from soil during the growing seasons o...

Conservation tillage and even no tillage as a practice is not new. However, there appears to exist evidence that in some cases no-tillage is successfully incorporated into a new concept of truly sustainable agriculture, gaining popularity as “conservation agriculture” all over the world. Conservation Agriculture is, besides no-tillage and direct planting, based on very old concepts such as gree...

This paper discusses the potential benefits from shade management in agroforestry systems for taro cropping. Trial work to evaluate weed growth, taro production, and cultivar responses to shade levels are reviewed. It is concluded that weed growth can be reduced in tree-shaded plots without reducing corm production. Higher crop biomass is obtained when taro is grown under fifty percent shade co...
