Abstract: An investigation was carried out to study the effect of foliar application of micromutrients viz Zn. Fe and B singly or\"\' combination on growth. yield and quality of \'banana cv. Martaman (AAB. Silk). Combined application of Fe (0.5%) and Zn (0.5%) showed the best response on plant growth in terms of plant height, basal girth of pseudostem. number of leaves produced per plant and minimum duration between emergences of two successive leaves. The micronulrient induced inarked improvement in days lo shootmg. days to bunch harvest and total crop duration (day.I) The leaf micronutrienls content 111creased due to application of different micronulrienls except in case of boron. Applicat10n 0f Fe (0.5%) + Z11 (05%) recorded maximus bunch weight (16.30kg). hands (9.2/ bunch), .fingers 29.2.bunch , yield (40.75t!lw), .finger length (I 4.80c111) . .fi11ger breadth (} 3.1 Ocm}. days to ripening 18. I days) and highest B. C ratio (3. 6 I). Spraying of Fe (().5%) and Z11 (0.5%) in comhmation shml\'ed maximum sugaracid ratio (41.698!. 11on-reducing sugar (10.040%) also sholl\'ed considerable improvement on total soluble solids !25.53°Brix) and to/{i/ sugar (/ 7.241%) content of pulp. Jn view of observation recorded. it can he concluded that combined applicmion of Fe (0.5%; ··Zn (0.5%) at 3.5 and 7\';,111011/h qf/1\'1\' planting of suckers gave better result in respect of growth yield. quality and B. C ratio of banana (AAB, Silk;) in Ca11get1c Plain of West Bengal.
