Cropping patterns are defined as the sequence and spatial arrangement of annual crops on a piece land. Knowledge cropping is crucial for crop production land-use intensity. While related to land use intensity, they rarely reported in agricultural statistics, especially those relating small farms developing countries. Remote sensing has enabled mapping by monitoring crops’ temporal dynamics. In ...

This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. The authors suggest agronomic practices, including tillage practices, rotations, and input management options that can ameliorate important constraints and sustainably improv...

The implementation of the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) in India in 2006, has voiced concerns about the possible adverse impact on agriculture due to a shortage of casual labour in the agriculture sector and an unfavourable shift in cropping patterns. At the same time, MGNREGA is also associated with investments in rural infrastructure. The scheme especially f...

[1] Farmers make joint water and land use decisions for economic purposes based in part on water availability and reliability. A two-stage economic production model is developed to examine the effects of hydrologic uncertainty and water prices on agricultural production, cropping patterns, and water and irrigation technology use. The model maximizes net expected farm profit from permanent and a...

In a runoff irrigation system using levelled basins, the water uptake patterns of different plant species (Acacia saligna (Labill.) H. L. Wend. and Sorghum bicolor (L.) Moench.) with contrasting root and shoot development were compared. Rainfall amounts during 1995 led to enough runoff water for realizing two cropping cycles. The amount of irrigation water was sufficient to fill the moisture-de...

In response to the need for generic remote sensing tools to support large-scale agricultural monitoring, we present a new approach for regional-scale mapping of agricultural land-use systems (ALUS) based on object-based Normalized Difference Vegetation Index (NDVI) time series analysis. The approach consists of two main steps. First, to obtain relatively homogeneous land units in terms of pheno...

Water resources sustainability is one of the major issues in the agricultural sustainability. In this study sustainability of water resources has been investigated by use of linear and non-linear models in six models based on optimal utilization of water resources in the north parts farms of Iran because of incorrect use of agricultural water resources, from 2011 to 2012. Also “gross margin per...
