One of the main problems in crop production in Iran is the difference between actual yield and attainable yield which is called yield gap. Thus, identifying yield constraints and yield gap are important. Therefore, a study was conducted in 60 farms in Parsabad Moghan, during 2013-14 and 2014-15 crop years using Comparative Performance Analysis (CPA). In this study, several attributes related to...

The objective of this study was to determine relationship between high resolution satellite image and wheat N status, and develop a methodology to predict wheat N status in the farmers’ fields. Field experiment with 5 different N rates was conducted in Huimin County in the North China Plain, and farmers’ fields in 3 separated sites were selected as validation plots. The IKONOS image covering al...

This paper examines the occurrence and impact of gender discrimination in access to production resources on the income, productivity, and technical efficiency of farmers. Through an empirical investigation of farmers from Koussin-Lélé, a semi-collective irrigated rice scheme in central Benin, we find that female rice farmers are particularly discriminated against with regard to scheme membershi...

[1] European water policy requires all EU Member States to implement volumetric water pricing at rates that roughly cover the total costs of providing water services. The objective of this paper is to develop a methodology that will enable us to analyze the differential impact that a water pricing policy for irrigation would have on heterogeneous farmers of an irrigated area. For this purpose, ...

This article investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favoured production environments of a developing agricultural economy. Drawing production data from household and plot surveys conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land deg...

In recent years, methods of fuzzy reasoning have been successfully developed for land evaluation. The accuracy of such land evaluation depends on the quality of weighing land characteristics with respect to their effects on crop production. This paper presents a spatially-based model of land suitability analysis. The main purposes were to (1) establish land suitability indices for irrigated whe...

In Egypt, recent shortfalls in the wheat supply from Russia and Ukraine have necessitated substantial increases domestic production. As agricultural practices influence yield of bread wheat, we assessed current production strategies wheat-based systems Egypt investigated their effects on productivity four study areas Nile Delta. We used a multi-stage random sampling technique to select 246 whea...
