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...

It is a common practice to grow winter wheat (Triticum aestivum L.) as a dual-purpose crop in the U.S. Southern Great Plains to decrease production risk and to increase profit margin through cattle (Bos taurus) production. Crop management of the dual-purpose wheat is complex because of the tradeoffs between beef production and wheat grain yield. A wheat grazing model helps in making optimal dec...

This study probes into the interplay of the factors operating on supply side of the wheat economy of Pakistan. The analysis is carried out to determine the performance of the agricultural policy of the country in securing a sustainable measure of self-sufficiency in food production. It is argued that, compared to the developed countries, the developing countries like Pakistan have done too litt...

One of the ways of haploid production is a cross between wheat and maize. Recently success has been achieved in this method, leading to the production of zygotes; these zygotes generally undergo elimination of maize chromosomes and thus lead to production of wheat haploid plant. The purpose of this study was to develop an efficient method of haploid production via maize pollination in short dur...

Agriculture of the inland arid region in Xinjiang depends on irrigation, which forms oasis of Northwest China. The production and water use of wheat, a dominant crop there, is significantly affected by undergoing climate variability and change. The objective of this study is to quantify inter-annual variability of wheat yield and water use from 1955 to 2006. The farming systems model APSIM (Agr...

Wheat is the main agriculture crop of Pakistan. For country planning, forecasting is the main tool for predicting the production of wheat to determine the situation what would be the value of production coming year. In this research, we developed time series models and best model is identified for the objective to forecast the wheat production of Pakistan. In this research large time periods i....

IPSIM (Injury Profile SIMulator) is a generic modelling framework presented in a companion paper. It aims at predicting a crop injury profile as a function of cropping practices and abiotic and biotic environment. IPSIM's modelling approach consists of designing a model with an aggregative hierarchical tree of attributes. In order to provide a proof of concept, a model, named IPSIM-Wheat-Eyespo...

Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics of landraces and modern bread wheat var...

The aim of this study is to estimate the green, blue and grey water footprint of wheat in a spatially-explicit way, both from a production and consumption perspective. The assessment is global and improves upon earlier research by taking a high-resolution approach, estimating the water footprint of the crop at a 5 by 5 arc minute grid. We have used a grid-based dynamic water balance model to ca...
