water deficit and low nitrogen content of soil are the two major yield limiting factors in most maize (zea mays l.) producing areas. the objective of the current research was to evaluate the relationships between photosynthetic water and nitrogen use efficiency at different levels of soil moisture and nitrogen contents. a factorial experiment, based on completely randomized design with 3 replic...

as compared to ksc 704 hybrid with 9.844 t/ha, the maize hybrid, ksc 705(k3640/3 × mo17) produced an average grain yield of 11.120 t/ha over seven locations evaluated in final trials for two consecutive years (2007-8). in advanced yield trials done in 2011, across seven locations, this hybrid performed the highest grain yield, 10.450 t/ha, while ksc 704 produced 8.513 t/ha. in addition to the g...

maize hybrid ksc 706 (k3547/4 × mo17) produced grain yield 11.713 t ha-1, when evaluated in eight locations over two years (2007-8), comparing to ksc 704 with 9.845 t/ha. on farm experiments in 2012, in kermanshah province in two locations, this hybrid produced 13.100 and 13.300 t ha-1 in eslam abad and ravansar as first cropping, respectively, comparing to ksc 704, with 11.300 and 9.700 t ha-1...

maize hybrid ksc 703 (k47/3 x mo17) produced grain yield 12.034 t/ha over seven locations in 2010, compared to ksc 704 with 12.034 t/ha, as check. during two years evealuation ( 2011-2012) over 12 locations, this hybrid revealed grain yield 11.291 t/ha, comparing to ksc 704 with 9.506 t/ha, showing 1.785 t/ha (18.8%) yield increase. on farm experimants carried out in islam abad, ravansar, mahta...

twenty local and foreign maize (zea mays l.) hybrids in five different maturity groups were evaluated in mashhad, iran for two years (2007-2009). three planting dates (5th may, 20th may and 5th june) and hybrids were arranged in a randomized complete block design as split plot arrangements, with three replications. the planting dates were in main plots and hybrids in subplots. the results indic...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...
