Impact of bio-fertilizers and micronutrients on quantity and quality traits of sugar beet (Beta vulgaris L.)

The present study was carried out to investigate the effect of bio-fertilizers and micronutrients foliar application on the quality and quality of sugar beet cultivars in a factorial based on randomized complete block design with three replications in 2017.Experimental treatments consisted of four levels of chemical fertilizers and bio-fertilizers (F1: 100% chemical fertilizers)control), F2: 50% chemical fertilizers + bio-fertilizers (nitragin and Phosphatebarvar-2), F3: 25% chemical fertilizers + biological fertilizers (nitragin and Phosphatebarvar-2), F4: bio-fertilizers (nitragen and Phosphatebarvar-2), and micronutrients foliar application in 4 levels including: M0: distilled water, M1: zinc sulfate solution, M2: Mn sulfate solution, M3: zinc sulfate solution + Mn sulfate solution). The effect of fertilizer on biological yield, grain yield, harvest index, sugar percent, white sugar content, white sugar yield and sugar yield sugar content and -Amino-N were significant. The effect of micronutrients on biological yield, root yield, harvest index and extractable sugar content were significant. The maximum root yield (63.97 Ton.h-1) was observed in 50% chemical fertilizers + bio- fertilizers treatment. Also, Zn sulfate + Mn sulfate had the highest root yield (64.12 ton.h-1) and increased root yield by 4.5% compared to control (distilled water). The level of sugar by using bio-fertilizer increased by 14.3% compared to 100% chemical fertilizers. The maximum -Amino-N was observed in 100% chemical fertilizers treatment. The use of bio-fertilizers and micronutrients in sugar beet cultivation improved quantity and quality traits of sugar beet.
