chapter one is devotod to collect some notion and background informations, which are needed in the next chapters. it also contains some important statements which will be proved in a more general context later in this thesis. in chapter two, we show that if the marginal factor-group is of order np1...pk,n>1, then we obtain a bound for the order of the verbal subgroup. also a bound for the bear-...
With the continuous improvement of mechanization level and development new crop varieties, optimal strip width for intercropping crops is important. In this study, field experiments were conducted to analyze effects different row spacings planting patterns on photosynthesis, chlorophyll fluorescence, related enzyme activities maize ear leaves in a maize–soybean system using two (wide–narrow row...
Research results at other locations in western U.S. indicate that a plant spacing of approximately 12 inches within rows and 20 or 22 inches between rows is necessary to obtain near maximum yields of sugarbeets (Beta vulgaris 1..) and yet maintain adequate space for machinery operation (4, 6, 10). 3 Increasing row and plant spacings with corresponding decreases in plant population have reduced ...
To investigate the effect of different planting row ratios of parental lines and agronomic methods on synchronizing of flowering and seed production of SCK703 hybrid maize, a field experiment was carried out as a strip plot arranegemnts in randomized complete block design with three replications in southern Kerman agricukltural and natural rseraech and education center, Jiroft, Iran, in 2015 gr...
abstract: advertisements are the most accessible type of authentic materials, and this is one reason why they are used more and more in english teaching classes. for this cause, studies in the field of advertisements are very widespread nowadays. for pun is one aspect which makes advertisements more interesting, it is used more than before in advertisements. use of puns makes an advertisement m...
This study had the objective to evaluate effect of irrigation and fertigation (N) in crop yield its impact on total cost, addition influence conductivity hydraulic capacity logarithmic an Oxisol under vinasse application cultivated with sugarcane (second year), state Goiás, Brazil. The experimental design comprised randomized blocks a 5 × 2 factorial scheme, four replications. Treatments consis...
plant dry matter accumulation has a linear relation with accumulative photosynthetically active radiation (par). intercropping could be a strategy for increasing light absorption in agronomic systems and it may improve radiation use efficiency (rue). thus this study was conducted in order to evaluate radiation absorption and use efficiency in potato (solanum tuberosum l.) –corn (zea mays l.) in...
