Abstract Farmers in dryland regions are highly vulnerable to rainfall variability. This vulnerability is unequal, as it mediated by biophysical and social factors. Implementing policies for climate resilience requires identification of farmers who most extreme events like dry spells. We develop a novel approach conceptualizing spell at the farm scale terms monsoon crop water deficit. Using inpu...
In order to evaluate the productivity potential of some bread wheat varieties and promising lines under no-till rainfed condition two different on-farm trials were conducted in cold (Sonqor) and warm (Sarpol-e Zahab) regions of Kermanshah province during 2017-18 cropping season. In the cold condition, 12 winter genotypes and in the warm condition 32 spring genotypes were evaluated for grain ...
The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...

The growth status of winter wheat in irrigated field and rainfed field are obviously different and the field types may have an effect on the predictive accuracy of hyperspectral model. The objectives of the present study were to understand the difference of spectral sensitive wavelengths for leaf area index (LAI) in two field types and realize its hyperspectral prediction. In study, a total of ...
Wheat is widely grown in Iran as a staple food; therefore, the government there encourages farmers to produce wheat (a common agricultural enterprise) by increasing farm productivity and efficiency. The study compares the efficiency of wheat production for dryland (low input) and irrigated (high input) systems across Iranian provinces by using Data Envelopment Analysis (DEA). The average techni...
Abstract Rotating cereal crops (e.g., wheat [ Triticum aestivum L.] with a 10‐ to 21‐mo summer fallow period [fallow]) is common farming practice in dryland (rainfed) agricultural regions. Fallow associated several challenges including low precipitation storage efficiency, depletion of soil organic carbon (SOC), loss fertility, little crop residue retention and erosion, few control options for ...
Unlike the Central and Eastern U.S. Corn Belt where maize is grown almost entirely under rainfed conditions, maize in the Western Corn Belt is produced under both irrigated (3.2 million ha) and rainfed maize (4.1 million ha) conditions. Simulation modelling, regression, and boundary-function analysis were used to assess constraints to maize productivity in the Western Corn Belt. Aboveground bio...
Daily rainfall and evaporation data of 30 years (1969-1998) are analysed for prediction of hydrological events, such as occurrence of effective monsoon (EM) and withdrawal of monsoon (WM), for planning rainfed rice in Eastern India. Those hydrological events are treated with normal (ND), lognormal (LND), Pearson type 111 (PTD), and log-Pearson type 111 (LPTD) distributions. The historical data ...
