drought stress is one of the most important environmental stresses that affect yield of bread wheat strongly. considering that the yield achieved with the interaction of a large number of plant traits and environment, so the morphological and agronomical traits, can serve as selection criteria under environmental conditions. by genetic analysis and estimation of inheritance and mode of gene act...

To determine the effect of inorganic N fertilizer on the incidence of yellow stem borer (YSB), Scirpophaga incertulas Walker and on grain yield, yield attributes and bio-chemical characters of local paddy cultivar Tulaipanji, a field experiment for three consecutive years (2007-2009) was carried out by randomized block design in pesticide untreated field. Treatments comprised of seven different...

Identifying the underlying mechanisms and the sources of variation in plant productivity is critical to the development of accurate predictive models of ecosystem responses to environmental change, including increased nitrogen (N) deposition and altered precipitation patterns. A great deal of variation in aboveground net primary production (ANPP) in tallgrass prairie may be accounted for by var...

Reliability analysis of a power tiller involves studying the probability its performance and functionality over given period. This aims to identify factors that affect reliability determine ways improve performance. The can be evaluated using different methods such as statistical analysis, theory, simulation modelling. These enable assessment tiller's in operating conditions help critical compo...

Tillering is a core constituent of plant architecture, and influences light interception to affect plant and crop performance. Near-isogenic lines (NILs) varying for a tiller inhibition (tin) gene and representing two genetic backgrounds were investigated for tillering dynamics, organ size distribution, leaf area, light interception, red: far-red ratio, and chlorophyll content. Tillering ceased...
