Abstract

Study on screening of germplasm of banana was under taken during 2008-09 and 2009-10 under natural ephiphytotic conditions. The observations were recorded on to sigatoka leaf spot index of banana. All cultivars under study from four genomic groups have recorded susceptible to highly susceptible reactions to the sigotika leaf spot disease (Mycosphaerella musicola) of banana. During both the years of study, all cultivars were recorded susceptible category, of disease reaction. Among the nine cultivars from AAA group, the respective range of PDI were 11.43 to 31.33 and 22.35 to 38.52 for 2008-09 to 2009-10. During both years of study, the highest PDI was recorded with cv. MAHALAXMI. The least PDI was recorded with cv. SHRIMANTHI. The cv. SAFED VELCHI (AB) recorded PDI above 20 and also recorded susceptible reaction. The four cultivars from AAB group recorded PDI in the range of 8.35 to 21.53 and 20.14 to 28.32, respectively for 2008-09 and 2009-10.

Abstract

The field experiment to study the effect of microgranular sulphur (Cosavet Ferits WG) on soil properties, nutrient uptake, growth and yield parametes of banana was undertaken at Banana Research Station, Jalgaon during the years 2007 to 2009. Application of sulphur @ 12 g plant^-1 through Cosavet Fertis (WG) in two splits recorded significantly higher no. of hands per bunch, maximum bunch weight and yield over control. Application of sulphur @ 9 g plant^-1 through Cosavet Fertis (WG) in two splits recorded 137 fingers per bunch, 19.6 kg bunch weight and 87.0 t ha^-1 yield which was found at par with application of sulphur @ 12 g plant^-1 through Cosavet Fertis in two splits. Lower soil pH and EC were reported in the treatments where sulphur was applied through Cosavet Fertis (WG). Higher nutrient uptake was recorded in the treatment of sulphur @ 12 g plant^-1 through Cosavet Fertis (WG) in two splits.
