Future rice production problems are related to global warming and water scarcity due climate change. For efficient sustainable production, flood irrigation management high nitrogen applications must be modified. Among the main recommendations include incorporation of fertilizer at critical stages crop, use direct seeding in dry soil instead transplanting method. This manuscript brings together ...

in order to study effective factors in sugar beet production using two stage cluster sampling, totally one hundred producers were selected from kermanshah and islamabad cities in kermanshah province. data were collected through interviews and  filling out questionnairs for crop season 1999-2000. evaluation of technical efficiency of sugar beet producers and  its  effective factors was carried o...

There is an increase in awareness of the benefits of grass hay from an agronomic and nutritional perspective. The main cool season forage grass species adaptable to California are annual ryegrass, Italian ryegrass, perennial ryegrass, orchard grass and tall fescue. The main characteristics of these species along with attributes of different varieties are highlighted in this paper. The agronomic...

considering the efficiency studies play a role in making available the revise in relative importance, policy reforms and resource management, this study has been accomplished in fish beach seine cooperative companies located in golestan province and used dea approach to measure the technical efficiency (te) and factor effects. the survey data were gathered from 20 farms, which selected via cens...

Western scientists and development officials are often discomfited by the fact that farmers in the developing world rarely behave like the independent actors of neoclassical economics. Instead, farmers appear to be enmeshed in a social fabric, and their decisions often seem unduly guided by social factors such as customs, obligations, and beliefs. It is not surprising that many outsiders regard...

The main challenges for tree crop improvement are linked to the sustainable development of agro-ecological habitats, improving adaptability limiting environmental factors and resistance biotic stresses or promoting novel genotypes with improved agronomic traits [...]

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...

to study and determine  effect of salinity on relationship between  agronomic  characteristics and grain yield, 167  of  the  seri/babax recombinant wheat inbred  lines (ril) together with two parents were evaluated using alpha latice design with two replications under two conditions (salt stress and normal), in zabol field station in 2011-12 cropping season. fourteen  traits  including: some a...
