The effect of different levels of phosphorus from triplesuperphosphate fertilizer sources and biosuperphosphate fertilizer on yield and yield components of corn in the climatic conditions of Izeh

摘要

In order to investigate the biological application of bio superphosphate fertilizer and different quantities of triple superphosphate on yield and yield components of maize Mobin704, research was conducted in February 2012 in a field located in the city of Izeh. The present research was carried out in split plot in form of randomized complete block design, in three replications and two factors: the main factor consisted of 4 of triple superphosphate levels (application 0, 130, 65, 195 kg per hectare) and the sub-factor at two levels (application and in-application of bio superphosphate fertilizer). The results of this research indicated that the effect of phosphorus on the yield and yield components was significant in such as a manner that as the application of phosphorus level increased, seed yield, number of kernels in maize, number of seeds per row and weight of one thousand seeds significantly increased at 130 kg per hectare. The application of bio superphosphate fertilizer significantly increased seed yield and yield components. Combining treatments of bio superphosphate fertilizer and quantities of triple superphosphate fertilizer also increased yield and yield components of maize. Meanwhile the application of bio superphosphate fertilizer and 130 kg hectare of triple superphosphate had the highest seed yield and it had higher yield than other treatments in general
