understanding the relationship between sink and source in maize is of prime importance in maize growing regions. in this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the college of agriculture, shiraz university, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of  sc704 maize hybrid.  a fa...

Nitrogen (N) is an essential requirement for kernel growth in maize (Zea mays); however, little is known about how N assimilates are metabolized in young earshoots during seed development. The objective of this study was to assess amino acid metabolism in cob and spikelet tissues during the critical 2 weeks following silking. Two maize hybrids were grown in the field for 2 years at two levels o...

Abstract Biosolids are frequently used as organic soil additives. This 2-year field study investigated the effects of sewage sludge (SWS) application on maize ( Zea mays L.) production, nitrogen accumulation, redistribution, and use efficiency, well grain element concentrations properties. Treatments included three SWS rates (20, 40, 80 Mg ha −1 year ‒1 ), mineral fertilizer (300 kg N 26 P an u...

Heat stress during flowering is a critical limitation for summer maize production. However, the incidence of heat varies with years and locations, it poses great risk to successful reproduction kernel setting. Therefore, essential provide sound quantification occurrence in relation growth development. Here, we analyzed characteristics based on climate data over 60 Huaibei Plain, China. The effe...

The present investigation for studying correlations and path analysis estimates grain yield contributing characters in maize was carried out at Maize Research Centre Seed Farm, Devihosur eleven characters. Days to 50 per cent tasseling significantly positively correlated with days silking negatively plant height, ear cob length, shelling percentage, hundred weight yield. significant percentage ...
