VARIATION OF GRAIN NUMBER - EAR-1 AND -PLANT-1 TRAITS UNDER THE INFLUENCE OF TWO TREATMENTS OF WINTER WHEAT (TRITICUM AESTIVUM L.) VARIETIES
Essien Okon* and Vladimir Zuba
This study was carried out to investigate the variation of traits; grain number ear-1 and plant-1 in three winter varieties namely Batko, Diya and Krasnodarskaya 99 under the influence of the growth regulator, Furolan and mineral fertilizer. The grain quantity ear-1 and grain quantity plant-1are some of the basic traits which account for plant yield. For Deya's variety the grain number ear-1 varied from 37.4 pieces (control) to 38.2 pieces (the fertilized variant). The difference between the fertilized variant and control was 0.8 grains. This was a significant difference in grain number ear-1. The interaction of factors A and B on grain number ear-1 in Krasnodarskaya 99 variety varied from 37.6 pieces (control) to 39.1 pieces (the fertilized variant). The difference between these variants of Krasnodarskaya 99 in grain number ear-1 was 1.5 pieces. By application of only growth regulator the grain number plant-1 obtained was 68.2 pieces i.e. about 4.8 pieces more than the control. of By combined application of mineral fertilizer and growth regulator the grain number plant-1 obtained was 78.8 pieces which was 15.4 pieces more than control. All this increase in grain number plant-1 in all the variants was statistically significant.
