Extended abstract 1- Introduction Land-use change has been extensively considered by farmers as an easily available approach with the aim of finding new resources for producing more agricultural products. Deforestation, the most common type of land-use change, has led to the extensive parts of productive lands in different parts of the world being highly degraded. Rainfed farming can be liste...

The article reports influence of different environmental conditions on the productivity Linum usitatissimum L. (flax or flaxseed) in Uzbekistan. Analyses plant were carried out rainfed lands and Tashkent Botanical Garden. Phenological studies revealed differences various phases growing period. Morphometric parameters that determine yield seeds under determined. seed per average Garden was 79.4 ...

The success of the Green Revolution in closing the gap between world population and food production was principally achieved by increasing crop productivity in favorable areas. However, this success has been limited in the rainfed systems, which are prone to frequent droughts and other abiotic stresses. Worldwide, drought affects approximately 23 million hectares of rainfed rice. Varieties comb...

Understanding the relationships between climatic variables and soil physical and chemical properties with crop yields on large scales is critical for evaluating crop productivity to make better assessments of local and regional food security, policy, land and water resource allocation, and management decisions. In this study, ordinary least squares (OLS) regression models were developed to pred...

A significant portion of the Shirkouh lands in the Mehriz city encompass irrigated and rainfed orchards. The livelihoods of the people in this area are mainly supported through farming and raising livestock. Many orchard products, especially Amygdalus sp. are rainfed and produce a good crop in rainy years. However, in the drought years, the production faces problems. This research was carried o...

    Drylands cover about 6.2 million hectares of arable lands across Iran, but annual feed legumes are not present in rainfed crop rotations. Introduction of new forage cultivars with high productivity and nutritive values is a key solution in drylands development. Vd-2446 a vetch (Vicia dasycarpa) line with origin of Italy has been selected from vetch nurseries provided by ICARDA during 1995 a...

With the rising demand for food products and direct impact of climate change on production in many parts world, recent years have seen growing interest subject security role rainfed farming this area. Machine learning methods can be used to predict crop yield based a combination remote sensing data collected by ground weather stations. This paper argues that forecasting drylands reliable manage...
