an experiment was carried out in 2008 to investigate the effects of different irrigation regimes, and chickpea cultivars on chickpea production in the khorramabad lorestan. the experiment was split–plot in a randomized complete block design with 3 replications. supplementary irrigation at 8 levels (1-rainfed without irrigation, 2-irrigation after sowing, 3-irrigation at flowering, 4-irrigation ...

Gunungkidul Regency is known as an area that often experiences drought. On the other hand, also regency with highest amount of rice production in Special Region Yogyakarta Province. Rainfed paddy farming most widely developed type where irrigation needs are determined by rainfall. Decreased rainfall triggers meteorological drought can disrupt rainfed-based agriculture. This study aims to analyz...

Abstract Agricultural land in South Borneo has high rice productivity. The supporting factors for productivity are irrigation areas, one of which is the Maluka Baulin Swamp Irrigation Area (DIR). It located Kurau, Tanah Laut Regency. an area 421 ha (Decree Minister PUPR Republic Indonesia) now to 286 (land function and administrative other villages) with use as agricultural land. so far a low a...

In August 1990, a 2-ha plantation was established in an area where rainfall (about 515 mm year(-1)) was insufficient to meet evaporative demand. On nine occasions between September 1991 and April 1993, pressure-volume curves were constructed for irrigated and rainfed Eucalyptus globulus ssp. globulus Labill. and E. nitens (Deane and Maiden) Maiden trees. During the experiment, rainfed trees exp...

Dry land farming in India accounts for 63% of the cultivated land of 144 million hectares. The crop production on these lands is dependent entirely on the natural precipitation, which is highly erratic in terms of spatial and temporal distribution during the crop-growing season. To address these problems, Government of India has accorded high priority to watershed approach for development of ra...

This article assesses sugarcane yield gaps (YG) in Brazil to determine the degree to which production can be increased without land expansion. In our scenario assessments, we evaluated how much of the projected sugarcane demand to 2024 (for both sugar and bioethanol) can be satisfied through YG closure. The current national average yield is 62% of yield potential estimated for rainfed condition...

The main objective of this study is to present an improved modeling technique called Vegetation ET (VegET) that integrates commonly used water balance algorithms with remotely sensed Land Surface Phenology (LSP) parameter to conduct operational vegetation water balance modeling of rainfed systems at the LSP’s spatial scale using readily available global data sets. Evaluation of the VegET model ...

Temporal NDVI signatures of the following land cover types in the Aral Sea Basin (ASB) were analyzed in MODIS data 2000–2012: Wetlands, bare land, water surfaces, natural vegetation and rainfed agriculture (in mountainous regions), low vegetation, rice cropping systems. Only the last class refers to cropland. All other classes were targeted to separate non-cropland or rainfed agriculture from t...
