to determine sugar content and root yield variation of new sugar beet hybrids under different irrigation levels, an experiment was carried out at zarghan agricultural research station offars agricultural and natural resources research center, shiraz, iran. the study was conducted as split block based on a randomized complete block design with three replications for two years, 2009-10, using lin...

Abstract Seasonal drought is the most important factor to limit the production of maize in the world. Using a split plot design, a two year field experiment was conducted to determine the effect of limited irrigation regime on yield, yield components and water use efficiency of sweet corn (Zea mays var. saccharata). Responses of three sweet corn varieties KSC403, Merit and Obsession to three di...

abstract in order to study the effects of irrigation regimes on yield and some qualitative characteristics of three cultivars of potato (solanum tuberosum l.), an experiment was conducted in 2009 in the research field of the college of agriculture, ferdowsi university of mashhad. a factorial experiment was arranged in a randomized complete block design with three replications. experimental fact...

this research was conducted under greenhouse conditions to evaluate the optimum combination of irrigation and fertilizer levels to attain the best yield and quality of tomato crop. the experiment was conducted by using a split-plot design with three replicates. irrigation levels were applied to the main plots and fertilizer levels to the sub-plots. for each experimental unit, the irrigation lev...

scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...

Chickpea is an important edible legume consumed worldwide because of rich nutrient composition. The physical parameters chickpea are crucial attributes for design processing and classification systems. In this study, effects seven different irrigation treatments on size, shape, mass, color properties seeds were investigated, machine learning algorithms used to estimate mass seeds. results showe...

Crop production is a process of multiple inputs (water and nutrients, etc.), and the relationships between the inputs and crop yield are very complex. This study used a model for data envelopment analysis (DEA) to evaluate the efficiency of irrigation-fertilization schemes for winter wheat in North China. The field experiments were conducted at the Xiaohe Irrigation Experiment Station in Centra...

The freshwater deficit is the major constraint to winter wheat production. Saline water irrigation could alleviate stress while increasing risk of soil salinization, which would result in yield reduction due additional salt stress. objective present study explore effect a straw-returning mode promote production under saline irrigation. A field experiment was conducted during growing seasons 201...

T he seminal discovery by Mosmann and Coffman (1) that long-term CD4 + T cell clones could be segregated into subsets that produce distinct types of cytokines opened the way for extensive study of how these subsets are generated and what role they play in immune regulation as it relates to disease. Following this observation it quickly became evident in a murine model of Leishmaniasis that CD4 ...
