Yield gap analyses of individual crops have been used to estimate opportunities for increasing crop production at local to global scales, thus providing information crucial to food security. However, increases in crop production can also be achieved by improving cropping system yield through modification of spatial and temporal arrangement of individual crops. In this paper we define the croppi...
Predicting the hydrologic consequences of biomass cropping systems requires an understanding of how different crops and management practices affect soil hydraulic properties across space and time. To inform such predictions, I investigated the impacts of five biomass cropping systems on the hydraulic properties of soils across a landscape gradient in wet, dry, and average rainfall years. I used...
With a growing world population and a trend towards more resource-intensive diets, pressure on land and water resources for food production will continue to increase in the coming decades. Large parts of the world rely on rainfed agriculture for their food security. In Africa, 90 % of the food production is from rainfed agriculture, generally with low yields and a high risk of crop failure. One...
Background: Intercropping is an important aspect than sole cropping to address the issues of rainfed agriculture as well organic under changing climate scenarios and it also helps in maximization productivity profitability by efficient utilization natural resources like light, land water. Moreover, intercropping improves soil fertility through atmospheric nitrogen fixation with inclusion legume...
Eucalyptus plantations occupy almost 20 million ha worldwide and exceed 3.7 million ha in Brazil alone. Improved genetics and silviculture have led to as much as a three-fold increase in productivity in Eucalyptus plantations in Brazil and the large land area occupied by these highly productive ecosystems raises concern over their effect on local water supplies. As part of the Brazil Potential ...
Continuous cropping changes soil physiochemical parameters, enzymes and microorganism communities, causing "replant problem" in strawberry cultivation. We hypothesized that soil nematode community would reflect the changes in soil conditions caused by long-term continuous cropping, in ways that are consistent and predictable. To test this hypothesis, we studied the soil nematode communities and...
The water crisis is a reality in Western Bahia. In this region, hydroclimatic monitoring system capable of providing availability information advance for users was implemented objectively to avoid conflicts. study, we proposed the integration between and linear programming method optimize agricultural net benefit considering scenarios rainfall delay or reduction. Case studies were demonstrated ...
In Mediterranean cropping systems, it is important to utilise marginal lands for the cultivation of native food crops. Previous research on Crithmum maritimum L., a species southern Europe, has focused its alimentary and chemical parameters. The aim present study was identify effects irrigation fertigation systems C. in systems. We planted seeds an organic farm Italy, we carried out three exper...
Abstract This study aims to determine the potential and limitations of land in Ngawi District, East Java, Indonesia, for cultivating rice, corn, soybeans. The research consists a four-stage field conducted Regency: (1) organization units; (2) determination observation points through stratified proportional sampling each unit; (3) surveys; (4) laboratory analysis. evaluation was accordance with ...
Despite recent progress, computational visual aesthetic is still challenging. Image cropping, which refers to the removal of unwanted scene areas, is an important step to improve the aesthetic quality of an image. However, it is challenging to evaluate whether cropping leads to aesthetically pleasing results because the assessment is typically subjective. In this paper, we propose a novel casca...
