a field experiment was conducted in order to study the effect of nitrogen fertilizer and plant density on yield and quality of maize (zea mays l.) cultivar, mv500 silage as second crop. this study was conducted in agricultural research station of kurdistan university during 2012 growing season. the experiment was laid out as split plot based on randomized complete block design with three replic...
in this research, several chemical extractants and modified olsen methods were studied in 25 surface-calcareous soils (0-30 cm) for determining available phosphorus (p) for corn (zea mays l.) plant. in this experiment, the highest correlation was obtained between extracted p by olsen and colwell methods (nahco3-extractable p) and dry weight of corn shoot (r =0.67 and 0.75, p
Objective: Field experiment was conducted in 2009 to investigate the effects of plant density and weed interference on morphological characteristics and yield of corn (Zea Mays, L.) at Research Station of University of Tabriz, Tabriz, Iran. Methods: The experiment was arranged as split plot based on randomized complete block design with three replications. Plant density (D1, D2, D3 and D4: 5, 7...

in order to study the effect of plant density and sowing date on ear economic yield and sugar content in sweet corn (zea mays l. cv. saccarata), a field experiment was conducted at tarbiat modarres university (tehran west) in 2004. the experiment was carried out using split plots based on randomized complete block design of 4 replications. four levels of sowing date (may 22th, june 10th, july 1...
Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector. In addition to step-by-step laboratory transformation proced...

To determine the optimal ploughing depth and to make tillage simpler and less costly, but also taking account of edaphic and climatic conditions as well as biological and agrotechnical requirements of crops grown, long-term investigations (1994-2009) have been carried out on Stagnic Luvisol of sloping terrains in central Croatia near Daruvar. Th e paper presents the results relating to plant de...
