Controlled-release nitrogen fertilizer (CRNF) is expected to meet the nutrient demands for crop growth with single application, so as achieve high-yield, high-efficiency, and labor-saving cultivation. However, under current CRNF practices, a application of in winter wheat (Triticum aestivum L.) usually fails satisfactory effects due insufficient (N) supply later stage, contributing premature le...

MicroRNAs (miRNAs) have been shown to play crucial roles in the regulation of plant development. In this study, high-throughput RNA-sequencing technology was used to identify novel miRNAs, and to reveal miRNAs expression patterns at different developmental stages during rice (Oryza sativa L.) grain filling. A total of 434 known miRNAs (380, 402, 390 and 392 at 5, 7, 12 and 17 days after fertili...

Degraded soils in Northwest China are mostly nonproductive due to imbalanced nutrient and inadequate water supply. The effects of manure application at three different rates (7.5, 15.0, and 22.5 t ha) combined with chemical fertilizers on soil water and Water-Use Efficiency in maize [compared with chemical fertilizers (control)], under semi-arid conditions in dark Loessial soil and over a perio...

the experiment was performed to evaluate the morphological, phenological and yield aspects of two different echinochloa species, including barnyardgrass (e. crus-galli) and watergrass (e. orizoides) as a new-introduced weed species. the study was conducted as a 2-years pot-experiment under outdoor condition at rice research institute of iran (rrii) in rasht. the results demonstrated that; time ...

Breeding programs for increasing spikelet number in rice have resulted in compactness of the panicle, accompanied by poor grain filling in inferior spikelets. Although the inefficient utilization of assimilate has been indicated as responsible for this poor grain filling, the underlying cause remains elusive. The current study utilized the suppression subtractive hybridization technique to iden...

The objective of this study was to estimate inheritance of the grain filling rate as indicator for heat tolerant genes. The minimum number of genes for the trait in bread wheat was also assessed by combining quantitative genetic estimates and SSR marker analyses. Two cultivars, Debra (heat-tolerant) and Yecora Rojo (heat-sensitive) crossed and F1 and F2 populations generated. The parents, F1 an...

A newly developed wheat cultivar NARC 2011 was evaluated for physioagronomic traits by varying Humic acid concentrations and Effective microbes at different phenological stages during rabi season of 2010-11 in the field area allocated to national coordinated wheat program of national agricultural research centre, Islamabad. The experiment was laid out using randomized complete block design (RCB...
