Rice (Oryza sative L.) is the main food crop in Asia and the staple food of the majority of the population in many regions of the world. The population pressure in rice-consuming countries demands that more attention be directed towards new approaches to sustainable rice produc‐ tion. Improvement of both crop quality and yield is an urgent task [1]. Optimally, rice yield improvement must be sou...

The productive capacity of soils is directly associated with their organic matter content which is the main reservoir of organic carbon and main source of nutrients for plants (Grandy et al., 2006; Studdert et al. 1997; Sisti et al., 2004; Urquiaga et al., 2004). A sustained increase in the concentration of organic carbon is needed to establish a land management system where the degradation of ...

To satisfy future demands, the increase of wheat (Triticum aestivum L.) yield is inevitable. Simultaneously, maintaining high crop productivity and efficient use of nutrients, especially nitrogen use efficiency (NUE), are essential for sustainable agriculture. NUE and its components are inherently complex and highly influenced by environmental factors, nitrogen management practices and genotypi...

Regaining the agricultural potential of sodic soils in the Indo-Gangetic plains necessitates the development of suitable salt tolerant rice varieties to provide an entry for other affordable agronomic and soil manipulation measures. Thus selection of high yielding rice varieties across a range of sodic soils is central. Evaluation of breeding lines through on-station and on-farm farmers' partic...

A pilot-scale study was undertaken to evaluate alternatives to the solid waste management of a Central American municipal market located in Estelí, Nicaragua. The municipal solid waste from the local market is the second largest contributor to the municipal solid waste (MSW) stream. Waste from the market without any previous sorting or treatment is open dumped. The options evaluated in this stu...

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Maintenance and improvement of soil quality in continuous cropping systems is critical to sustaining agricultural productivity and environmental quality for future generations. This review focuses on lessons learned from long-term continuous cropping experiments. Soil organic carbon (SOC) is the most often reported attribute from long-term studies and is chosen as the most important indicator o...

The use of Geographical Information Systems (GIS) for agronomic purposes is traditionally associated with installations of conventional monolithic Farm Management Information Systems (FMIS). In these cases all data are stored in a single office computer, which is a bad pre-condition for Cloud Computing as well as low bit rates in many rural regions. Nevertheless there are already good technical...
