Effect of slow-release nitrogen fertilizer on morphologic traits of corn (Zea mays L.)
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 2
Abstract
Nitrogen is one of the main elements required for plant growth. Loss of 30-50% of N fertilizers is a frequently debated problem. However, this problem can be mitigated to some extent by application of slow-release fertilizers. Therefore, to investigate the effects of Nano polymer-trapped N fertilizers on morphologic traits of corn, polymer-trapped fertilizer was produced in laboratory. Then, in order to investigate the effects of synthesized fertilizers on morphological traits of corn, an experiment was carried out in a randomized complete blocks design with three replications. The treatments included non-trapped urea fertilizer (Control) and urea fertilizer trapped with nine different ratios of Nano structured polymers such as polyacrylonitrile and cellulose acetate. The results showed that polymer trapping of urea fertilizers led to improvement in morphological traits such as stem diameter, plant height, corn length, diameter and weight of corn stock, number of kernels per ear, seed weight in corn, 1000- seed weight, biologic yield, seed yield, and harvest index. The maximum rate of most traits under investigation was obtained in P1315 treatment. Therefore, due to its slow and long release of nitrogen, porous polymeric nanostructured fertilizer containing Urea provides adequate amounts of nitrogen during corn plant's growth process.
