Title
Influence of bio-fertilizers on yield and yield components of maize (Zea mays L.) single cross 260 in drought conditions
Authors
Abstract
Abstract
To investigate the effect of bio-fertilizers on yield and yield components of maize single cross 260 under drought stress an experiment was conducted during 2013 Experimented design was split plot randomized complete block design with four replications. Irrigation treatments consisted of the cumulative evaporation of 60, 90 and 120 mm of pan evaporation as a main factor and fertilizer treatments (chemical and biological) as subplot. Results showed that the effect of fertilizer treatments on all traits were significant. Maximum height and grain yield of 100% chemical fertilizer and normal irrigation treatments and then combined treatment of bio-fertilizer and chemical, with about eight percent decrease compared to the first treatment, was the highest yield. Effects of cutting treatments and the results proved that the use of bio-fertilizer Aztvbarvr 1 as roads can partially reduce the negative effects of stress.
