EVALUATING THE INFLUENCE OF MINERAL FERTILIZERS IN THE GROWTH AND YIELD OF YANTAR DURUM WHEAT CULTIVAR IN CENTRAL KAZAKHSTAN'S KARAGANDA REGION

Abstract: A field experiment was conducted to evaluate the effectiveness of mineral fertilizers on the growth, yield and yield parameters for durum wheat in the Karaganda region of central Kazakhstan. The experiment was a 10×3 factorial fitted into a complete randomized design, and treatments replicated three times. The treatments consisted of a control plot, with sole and combined Nitrogen (ammonium nitrate) and phosphorus (Ammophos) fertilizers (N₃₀, N₆₀), (P₉₀, P₁₂₀, P₁₅₀, P₁₈₀) and (P₉₀N₃₀, P₁₂₀N₆₀, P₁₂₀N₉₀) respectively. Analysis of variance (ANOVA) was carried out on soil and plant data, and their means separated using turkey t-test, while a spearman rho correlation analysis was done to show the relationship between growth, yield and yield. The results obtained showed that mineral fertilizers had significant impact on growth and yield of durum wheat. Though sole application of P and combined N x P had an impact on growth of durum wheat, this effect was not significant (p>0.05). similarly, mean yield attributes were not significantly affected by mineral fertilizers except for grain yield. The highest grain yield was found for P₁₂₀ (8.86 c/ha), followed by P₉₀N₃₀ (8.76 c/ha) and P₉₀ (8.63 c/ha) while for N-N₆₀ (8.06 c/ha). Spike length strongly correlated with plant height (0.952***), grain yield significantly correlated with root length (0.689*) and 1000-weight grain (0.709*), number of grains positively correlated with plant height (0.806*) and spike length (0.806*) while grain weight significantly correlated with plant weight (0.640*) and spike weight (0.706*). Harvest index however was highest for N₆₀ (9.14%) and P₉₀ (8.30%) indicating higher proportion conversion of plant total biomass into grain. Thus, the sole application of these fertilizers is recommended.
