Effect of pre-sowing seed treatment and spraying of bio-organic nutrient on yield and yield components of maize (Zea mays L.)
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 9
Abstract
To study effect of bio-organic nutrients on maize (SC 704) this experiment was done with eleven treatments based on a Randomized Complete Block design in three replications. Treatments consist of Humax, Marmarin, Biomix, Nitroxin, Distil water and Control that applied separately as pre-sowing seed treatment and foliar application. Row number per ear, ear diameter, number of grain per ear, 1000-grain weight, seed yield, biomass yield and harvest index of corn plants in both pre-sowing seed treatment and spraying methods have significant differences compared to mean control value. Maximum (4.76 cm) and minimum (4.1 cm) ear diameter was obtained in plants that treated with Humax as pre-sowing seed treatment and control plants, respectively. Results showed that the plants treated with Humax in foliar application and pre-sowing seed treatment had a maximum row number per ear and the control plants had the minimum of it. Application of Humax in both methods causes the highest number of grain per ear and the lowest belonging to the control. Plants treated with Humax showed the increase in 1000-grain weight in both pre-sowing seed treatment and foliar application method. The highest grain yield observed in plants treated with Nitroxin at pre-sowing seed treatment method and the lowest mean value of it obtained by control. The highest (30554 kg/ha) mean value of biomass yield was obtained from the plants that sprayed with Humax fertilizer. Generally, application of Humax as with pre-sowing seed treatment and foliar application lead to increase in yield and yield components of maize.
