Study of rice varieties yield and yield components response to iron nano composite apply in different growth stages
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 18
Abstract
Iron is one of necessary elements for the plant and plays a basic role in chloroplast organelle. Also plays an important role in the plant growth and yield and elements balance. To study of the effect of iron nano composite on major agricultural properties of transgenic and native varieties, an experiment was conducted in 2011 in Rasht (49º38' E and 37º12' N) as split plot with complete randomized blocks design in 3 replications. Investigated factors were including transgenic (khazar) and native (Hashemi) varieties of rice as main factor and 8 stages of spraying iron nano composite as sub factor. Results of variance analysis indicated significant difference for properties including yield, 1000 grains weight the healthy grains number in ear and the hollow grains number in ear. Study of interaction between rice varieties and spraying the iron nano composite in different growth stages indicated that spraying the iron nano composite on transgenic variety, (khazar), in two stages including and initial ear growing increased the yield from 5.08 ton. ha-1 to 8.14 ton. ha-1 which accounts for highest rate compared to other treatment combinations.
