The investigation of growth reducer Cycocel effect on yield and some quantitative characteristics of rice (oryza sativa) at different nitrogen levels
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 2
Abstract
Lodging at the maturity is one of the native cultivars cultivation problems in Guilan province. Using growth reducer such as Cycocel to increase the tolerance to lodging is a strategy permits more application of nitrogen to receive higher yield. Therefore an experiment was conducted in 2012 as split plot in complete randomized blocks design with 3 replications in Rasht (north of Iran). Nitrogen manure of Urea source with was 3 levels (0, 150 and 300 kg.ha-1) as main factor growth reducer Cycocel with 0, 1500 and 3000 ppm concentrations was considered as sub factor. Variance analysis results for treatment combinations as well as various concentrations of Cycocel indicated significant difference (0.01) for all the studied characteristics. Comparing the mean of the treatments interaction also indicated that native cultivar, Hashemy, has achieved 4.77 ton. Ha-1 yield by using 300 kg/ h nitrogen and 1500 ppm Cyclocel spraying.
