population growth as well as global fresh water shortage problem have necessitated the use of unconventional water resources in agricultural sector, as the largest consumer of fresh water, especially in arid and semi-arid regions. in this study, the effect of four irrigation methods on yield, uptake of water and important nutrients, and the salt accumulation in soil was investigated using a com...
Agricultural practices are continually changing at various spatial and temporal scales in response to local management decisions and environmental factors. However, few regional scale land use/land cover (LULC) classifications have focused on characterizing the agricultural sector, particularly on a regular basis to reflect croprelated land use changes that occur from year to year. More detaile...
Climate change is projected to push the limits of cropping systems and has the potential to disrupt the agricultural sector from local to global scales. This article introduces the Coordinated Climate-Crop Modeling Project (C3MP), an initiative of the Agricultural Model Intercomparison and Improvement Project (AgMIP) to engage a global network of crop modelers to explore the impacts of climate ...
Farmer Exchange Rate (FER) in Indonesia is very concerning. According to BPS data, there are various regions that experience increases and decreases every year. The goal of this paper predict the food crop sector using Principal Component Regression (PCR) since multicollinearity data. Therefore, with PCR method data based on 33 different provinces can determine supporting factors. model used he...

Background Despite its importance as a widely-planted crop tree, eucalypt species and hybrids are relatively difficult to micropropagate, culture and genetically transform in vitro. Compared to other plant species, few non-commercial laboratories are proficient at Eucalyptus tissue culture and transformation. We have undertaken to establish and transform several eucalypt clones in the laborator...
