Effect of Biofertilizer EM-1 and Stimulation Hormone (Biozyme) on Growth and Yield of Potato Solanum tuberosum L.

Abstract

An experiment was conducted during the Spring seasons of 2015 in private field in Babil province / Al-Hashimia district about 25 km south of Hillah city, to study the effect of Biofertilizer EM-1 and stimulation Hormone (Biozyme) on growth and yield of potato. This experiment was designed according to (R.C.B.D) with three replicates and two factors. The first included two levels of EM-1 ( 0 , 2 ml.L-1) and the second factor was three levels of Biozyme (0, 0.5, 1 ml.L-1). Result showed that using biofertilizer EM-1 and stimulation Hormone (Biozyme) showed a significant effect in growth and yield characteristics. The treatment EM-1 2 ml.L-1 gave highest average in ( plant height, total yield, N% , P%, and K % in tubers) as compared to control treatment which gave lowest average. While the stimulation Hormone treatment Biozyme 1 ml.L-1 gave highest average in ( plant height, total yield, and K % in tubers ) as compared to control treatment which gave lowest average. The duple interaction treatment biofertilizer and stimulation hormone showed a significant increase in growth and yield characteristics. The treatment EM-1 2 ml.L-1 +Biozyme 1 ml.L-1 gave highest average in( plant height, chlorophyll content, leaves number , leaves dry mater % , number of tubers, yield of one plant , total yield and K% ) as compared with control treatment which gave lowest average. In addition to that, the treatment EM-1 2ml.L-1 + Biozyme 0.5 ml.L-1 gave highest average in N% , P% and protein in tubers as compared with control treatment which gave lowest average. while the treatment Biozyme 1 ml.L-1 gave highest average in K% as compared with control treatment which gave lowest average.
