To study the effect of fertilizer and planting pattern on chickpea and linseed plant traits in dryland farming, a field experiment was conducted in factorial layout based on randomized complete block design with three replications in Naqadeh, Iran during growing season of 2016-2017. Treatments were included six substitutive cropping patterns; sole cropping of chickpea, sole cropping of linseed,...

Due to expansion of urbanization, introduction of advanced technology in the agriculture systems and low returns in traditional farming systems, farmers of the Central Development Region of Nepal were compelled to change the traditional farming systems to modern systems. The present study aims to find out the factors that affected the changes in cropping patterns in hills and plains of this reg...

Human population growth in the developing world drives land-use changes, impacting food security. In India, the dramatic change in demographic dynamics over the past century has reduced traditional agricultural land-use through increasing commercialization. Here, we analyze the magnitude and implications for the farming system by the introduction of cash-cropping, replacing the traditional slas...

A mathematical programming model is proposed for optimal cropping patterns under water de®cits in dry regions. Crops may be deliberately under-irrigated in order to increase the total irrigated area and possibly the pro®t. An operating policy will identify both the total area and the irrigation level allocated to a given selected crop taking into account the possible successors and predecessors...

Mapping crop patterns with remote sensing data is of great importance for agricultural production, food security and agricultural sustainability. In this paper, a hierarchical clustering method was proposed to map cropping frequency from time-series Moderate Resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Indices (EVI) data and the spatial and temporal patterns of cropping freq...

BACKGROUND Harnessing beneficial microbes presents a promising strategy to optimize plant growth and agricultural sustainability. Little is known to which extent and how specifically soil and plant microbiomes can be manipulated through different cropping practices. Here, we investigated soil and wheat root microbial communities in a cropping system experiment consisting of conventional and org...

The production and acreage of corn in Iran and in Fars Province, in particular, are expanding at an increasing rate. The impacts of this event was studied by a risk programming model (MOTAD). The results indicated that the optimal cropping patterns with corn had less variance than the optimal patterns without corn in all income levels. The results also showed that with the introduction of corn ...

We investigate how the receipt and amount of domestic or international transfers influences household decisions regarding farm investment selection capital labour-intensive crops. argue that, even though recipient households may use additional income to increase agricultural investment, can fall in short run if labour constraints arising from migrant member's absence are binding accumulation is...
