in order to investigate the effect of organic and chemical fertilizers on growth characteristics of marjoram, a factorial experiment was conducted based on randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad during 2012-2013 growing season. treatments were comprised of four urea levels (0, 21.7, 108.7 and 195.7 kg.ha-1) a...

Wheat lodging provides important reference information for self-adaptive header control of a combine harvester. Aimed at real-time detection wheat lodging, this paper proposed method location and area based on binocular vision. In method, the angle relationship between stem vertical direction when is upright, inclined, was determined by mechanical analysis. The discrimination condition degree h...

Semi-dwarf genes have been used to alleviate lodging and increase harvest index in barley. The present study was conducted determine the effect of widely sdw1.d allele on agronomic characters. transferred from cv. Triumph Tokak 157/37 using marker assisted backcross breeding, a near-isogenic line developed. Parents + near isogenic were evaluated three rainfed, fall-planted seven spring-planted ...

Dwarf stature is introduced to improve lodging resistance and harvest index in crop production. In many crops including maize, mining and application of novel dwarf genes are urgent to overcome genetic bottleneck and vulnerability during breeding improvement. Here we report the characterization and expression profiling analysis of a newly identified maize dwarf mutant Dwarf11 (D11). The D11 dis...

In response to the production crisis caused by a winter feed shortage due rapid development of animal husbandry industry, rye 001 was selected study differences in stalk and senescence characteristics yield formation cold regions. Five density treatments were established randomized design as 225 × 104 plant·hm−2 (D1), 275 (D2), 325 (D3), 375 (D4), 425 (D5). Stem characteristics, SOD activity, P...

Periodic measurements of plant height could be used to calculate growth rate and have potential for characterizing spatial variation of plant response to inputs and field conditions. A corn plant height measurement system using stereo machine vision was developed. A test apparatus was developed, which consisted of an x-y translating sensor platform with a CCD camera and an imaging stage for cam...

the objective of this study was to obtain relationships between plant leaf area (cm2plant-1) with leaf dry weight (g plant-1), vegetative dry weight (g plant-1) and plant height (cm) in faba bean (vicia faba l.). the experiment was conducted at the research farm of gorgan university of agricultural sciences in 2011-2012 growing season. the experimental design was a randomized complete block des...
