in order to evaluate the effects of different levels of water and plant density on yield, yield components, morphological and physiological characteristics of a new corn hybrid (ksc 500), an experiment was carried out in 2006 in karaj area. the experimental design was split plot based on randomized complete blocks design with three replications. main plots were three irrigation levels: 75%, 100...
Bio-fertilizers are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. This investigation was aimed at determining the effect of Nitroxin bio-fertilizer application on growth, inoculation and yield production of corn hybrids. An experiment was conducted as split plot on the basis of randomized complete block design with fou...
background: considering differences in head size and shape of different equine breeds, biometric parameters can be an attribute to a particular race. objectives: the purpose of the present paper is to give a numerical definition of morphological characteristics of head region of the darehshori horse. methods: twenty mature darehshori horses were studied biometrically. the ear length, ears dista...
in order to study the effect of sowing date and plant density on ear of sweet corn an experiment was conducted in gorgan reaserch station since june 2001 during 3 years. in this experiment five sowing date (24th june, 9th july, 24th july, 18th agust and 23th agust) and four plant density (45000, 55000, 65000 and 75000 plant per hectar) were evaluated in form of factorial experiment (5×4) within...
in order to study of the effect of nitrogen source, operation method and weed control methods on weed biomass, yield and yield components of corn (zea mays l.) an experiment was carried out as split plot factorial based on randomized complete block design (rcbd) with four replications in shahrood university of technology. the treatments included weed control methods at four levels (hand weeding...
Diallel crosses of six breeding inbred lines of corn (Zea mays L.) were used to estimate combining abilities, heterosis and some other genetic parameters for yield and some of its components. Parents, 15 F1 crosses and 4 filler genotypes, were evaluated in a 5×5 simple lattice design. For all the traits studied, except seed length, the efficiency of lattice design was less than one. Therefore, ...
Mycorrhizal fungi can be integrated in soil management to achieve low-cost sustainable agricultural systems. Hence, the effects of non-using (M1) and using (M2) of mycorrhizal fungi on reduction of phosphate fertilizer consumption, growth and yield of maize under different levels of phosphate fertilizer (P1: zero, P2: 20, P3: 40, P4: 60, P5: 80 and P6: 100% recommended) were investigated in a f...
Aim and Background. Since chemical control of corn common smut disease to be unsuccessful (that its agent is Ustilago maydis), screening of resistance hybrids to smut disease is necessary for maize breeding. Materials and Methods. In this study, 89 single crosses hybrids including 60 single crosses derived from hybridization of 20 S6 inbred lines as female parents and 3 S6 commercial elit tes...
to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...
In order to define normal values for ear length and position in the newborn infant, 198 (87 term and 111 preterm) infants were examined. In every case gestational age was determined chronologically and clinically. Ear length was measured from the superior to the inferior aspects of the ear. Using a horizontal line passing through the inner canthi of the eyes the portion of the ear above this li...
