VARIATION OF QUANTITY OF STALKS- AND PLANTS- M-2 AND PLANT BUSHINESS TRAITS OF WINTER WHEAT (TRITICUM AESTIVUM L.) VARIETIES UNDER THE EFFECT OF DIFFERENT TREATMENTS AT EAR-FORMATION PHASE.
Essien Okon*, Hannah Edim Etta and Vladimir Zuba
This investigation was carried out to study the effect of growth regulator, Furolan and mineral fertilizer on the traits; quantity of stalks / plants m-2 and plant bushiness at ear-formation phase in three winter wheat varieties namely Batko, Diya and Krasnodarskaya 99. By means of three-factorial dispersion analysis the influence of different kinds of variation on the formation number of productive stalks m-2 was determined. The number of productive stalks m-2 subjected to the effect of factor A (variety) varied as follows: Deya (653 stalks); Bat’ko (661 stalks) and Krasnodarskaya 99 (679 pieces). For factor B (mineral fertilizer) the number of productive stalks varied from 614 pieces (control) to 715 pieces m-2 (full dose of mineral fertilizer). The difference between control and the fertilized variants was 101 stalks m-2 (LSD05-factor B = 8.25). However, for factor C (growth regulator) the amount of productive stalks varied from 644 pieces (without treatment) to 685 pieces m-2 (Furolan –treated plants at the harvest output phase). The difference in these variants on the average was 41 stalk m-2 (LSD05 − factor C = 8.25).
