paddy de-awning using a de-awner increases the uniformity and flow rate of paddy grains through the orifices of hoppers, bucket elevators and chutes. in this study the effects of paddy variety, rotational blade speed and moisture content on performance of a prototype de-awner machine were investigated. the experiment was conducted in a factorial design with three factors, variety (hashemi and b...

The reproductive stage of rice is vulnerable to heat stress, which reduces spikelet fertility and yield. Auxin significantly influences development, hence the research aimed enhance grain attributes in plants by exploring application efficiency Indole-3-acetic acid (IAA) 1-naphthaleneacetic (NAA) under stress. This study investigated effects IAA (10 μmol L−1) NAA (100 on rate six genotypes duri...

A diallel cross experiment of 4 rice (Oryza sativa L.) female and 6 male varieties was conducted to study the genetic effects and their interaction with salt-stress condition of 7 agronomic traits in normal and salt-stressed planting conditions. The panicle length (PL), effective number of panicles per plant (ENP), plumped number of grains per panicles (PNG), total number of grains per panicles...

Two winter wheat cultivars (the functional stay-green CN12 and non-stay-green CN19) were used to investigate the effects of ear-shading on grain yield and to elucidate the differential mechanisms of different cultivars. The photosynthetic parameters, chlorophyll fluorescence, antioxidant enzyme activities, and chlorophyll contents were measured 0, 15 and 30 days after heading (DAH) under both s...

In the present study, large number of rhizobial strains were isolated from chickpea, lentil and mung been nodules and twenty fast growing colonies of each host legume, were selected. A series of jar experiments were executed and three most efficient isolates of each rhizobium species were screened on the basis of their growth promoting activities under axenic conditions. Results revealed that, ...

An experiment was conducted to investigate the effects of feeding a blend of grains naturally contaminated with Fusarium mycotoxins on growth and immunological parameters of starter pigs. A polymeric glucomannan mycotoxin adsorbent (GM polymer, Alltech Inc., Nicholasville, KY) was also tested for its efficacy in preventing Fusarium mycotoxicoses. A total of 150 starter pigs (initial weight of 9...

The lack of fresh water for irrigation in the world, especially arid and semi-arid areas is often posed as a major problem agriculture, which requires research to valorize saline water. This work aims study impact chemical correction quality on barley. corrected waters were prepared from raw by applying doses calcium represented Ca(NO3)2 4H2O according their soluble sodium content, whose aim ba...
