Abstract

Phosphorus fertilizer application rate is high in Qazvin province’s corn cultivation, regarding its calceous soil and high need of corn to this nutrient. On the other hand, the P fertilizer application and distribution should be carried out carefully as this macronutrient is low-mobile and fast – fixing in the soil. In this experiment, after primary soil preparation and sampling, two seed sowing methods using a row-phosphorus planter (capable to insert fertilizer beneah the seed) and a common corn seed row planter (top-dressing fertilization) were compared to each other. The experiment layout was factorial based on complete randomized block design (CRBD) with four treatments and three replications. Seed corn cultivar “SC 704” was used as experimental material. The experiment was performed at Qazvin’s Feyz-Abad Research Station, Qazvin, Iran, for two years. Treatments included 1) common sowing method accompanying with top-dressing fertilization 2) sowing, using a drilled-fertilizing machine with its fertilizer insertion into the soil. In this treatment, triple super-phosphate was used in three rates: according to recommendation, %25 lower than recommendation, %50 lower than recommendation. The fertilizer was inserted in the depth of 5 cm beneath the seed. Yield, stem height, 1000-seed weight, ear length and diameter, leaf P and Fe and Zn concentrations, seed number per ear and seed number in ear circumference were measured. According to results; yield increased in a %15-27 rates in seed-beneath fertilization, in all three fertilization levels. On the other hands, %25-%50 decrease in fertilization rate did not affect or decrease yield significantly (a=1%). No significant difference was recorded in other measurements.
