Detasseling is used in hybrid corn (Zea mays L.) seed production to ensure harvested seeds have the desired genetic complement. Both mechanical and hand detasseling result in loss of some leaf tissue and plant N. The objective of this study was to determine if seed yield and quality and N content of grain and stover were affected by leaf removal during detasseling. The treatments evaluated were...

grain yield loss in rice (oryza sativa l.) caused by blast disease, magnaporthe grisea (hebert) barr, is a major concern of rice growers worldwide. blast is considered as the most injurious disease of rice in iran, resulting in severe loss especially to susceptible rice cultivars. in order to assess yield loss caused by blast pathogen and develop an appropriate model, different disease onsets a...

in this research the effects of mycorrhizal symbiosis and irrigation intervals on growth indices and grain yield of two sorghum cultivars was studied. field experiment was laid out as a split plot factorial based on randomized complete block design with three replications. irrigation intervals as main factor in three levels (7, 14 and 21days) and factorial combination of two sorghum cultivars (...

in recent years, surplus usage of chemical fertilizers and inattention the importance organic matter to improve soil fertility, leading to increasing use of chemical fertilizer, environmental pollution and etc. in order to study the different fertilizer levels (organic, chemical and combined) on yield of grain corn (s.c.704) experiment was conducted at the research farm faculty of agriculture t...

BACKGROUND Since demand for distilling wheat is expected to increase rapidly as a result of the development of the bioethanol industry, efficient production will become of increasing importance. Achieving this will require an understanding of the agronomic factors that influence both grain yield and alcohol yield. Therefore five field experiments using the winter distilling wheat variety Glasgo...

Information on maximum grain yield and its attributes are limited for double-season rice crop grown under the subtropical environment. This study was conducted to examine key characteristics associated with high yielding double-season rice crop through a comparison between an integrated crop management (ICM) and farmers' practice (FP). Field experiments were conducted in the early and late seas...

with increasing the world population, and needing to feed it, the yield enhancement of cereals crops is of the most important approaches meet this target, which is achieved via identifying the effective factors underlay yield of cereals like wheat. this experiment was conducted to evaluate the grain yield and its association with some contributed traits in a doubled-haploid (dh) wheat populatio...

the aim of this study was to investigate the genotype effect on nitrogen remobilization and its relationship with yield and grain protein concentration in genotypes of wheat during grain filling. twelve wheat cultivars different in origin and varying with grain yield and grain protein percentage were selected. a randomized complete block design was used. plants were harvested at anthesis and ma...
