Effect of Iron, Zinc and Silicon Application on Quantitative Parameters of Rice (Oryza Sativa L. CV.Tarom Mahalli)
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 5
Abstract
In order to investigate the effect of micronutrients foliar application on quantity parameters of rice (Oryza sativa (L.) cv. Tarom Mahalli), a field experiment was carried out as randomized complete block design (RCBD) with four replications in 2012. The treatments included foliar application of different mixtures of Zn, Fe and Si micronutrients as the rate of 3 /1000. Results showed that the effect of foliar application of these micronutrients on yield quantity parameters such as grain number per panicle, 1000 grain weight and biomass weight was significant. The highest grain number per panicle (varied from 137.21 to 153.43) was recorded when Fe+Si and mixture of the three elements were applied. Meanwhile, maximum 1000 grain weight (25.88 g) was obtained in Zn+ Si foliar application treatment. The simultaneously application of these elements had the highest biomass weight (10051.2 kg ha-1) and grain yield (4690.4 kg ha-1). Also, grain yield in Zn + Fe foliar application treatment (4259.0 kg ha-1) was 9 and 13 percent greater than those in Fe (3889.1 kg ha-1) and Zn (3705.9 kg ha-1) treatments, respectively.
