Abstract

To study the effect of biological phosphorous fertilizer and different quantities of chemical phosphorous fertilizer on KERNEL YIELD of maize cv. SC704 a field experiment was conducted in agricultural research farm of University of Tehran in Karaj, Iran, in 2009. Treatments were arranged as split plot in randomized complete block design with four replications. Experimental treatments included: three levels of biological phosphorous fertilizer; Barvar-2 (control, seed inoculation, seed inoculation + foliar application) and four levels of chemical phosphorous fertilizer (control, 20, 40, 60 kg.ha-1 of super phosphate triple). Results showed that the effect of biofertilizer was significant on KERNEL YIELD, number of kernel.ear-1, 1000 kernel weight, weight of kernel.ear-1, biological yield, HARVEST INDEX and ear diameter. The highest KERNEL YIELD (13131 kg.ha-1) belonged to seed inoculation + foliar application of biological phosphorous fertilizer. Results also showed that chemical phosphorous fertilizer had significant effect on all traits except the number of number of kernel.ear-1. The highest KERNEL YIELD (12855.8 kg.ha-1) was obtained in 60 kg.ha-1 of chemical phosphorous fertilizer. Furthermore, the interaction effect of treatments showed that the application of biological and chemical phosphorous fertilizers was significant on all traits except the number of kernel.ear-1, ear diameter and HARVEST INDEX. The highest grain yield was obtained from seed inoculation + foliar application with biological phosphorous and 60 kg.ha-1 chemical phosphorous fertilizers. Results of this experiment showed that the biological phosphorous fertilizer contains microorganisms which could solve phosphorous in the soil, promoted growth and uptake of phosphorous by maize plant and increased grain yield.
