ABSTRACT

​

Banana corm act as a storage material for supporting new side shoot/sucker. It nourishes them by providing the reserved nutrients elements, however amounts of nutrients reserve in corms are not known. The experiment was conducted to evaluate dry matter and essential macronutrients elements (N, P, K, Ca and Mg) of thirty-three corms of different banana genotypes belonging to three different genomic composition. Dry matter content in the corms of the genotypes varied between 5.54 % in Madhuranga bale (AAB) and 23.81 % in Giant Governor (AAA). The nitrogen level in the corms of the genotypes varied between 0.17 % in Champa-IV (AAB) and 1.08 % in Alpan-Manhar (AAB). The phosphorus level in the corms of the genotypes varied between 3.65ppm in H531 (AAB) and 46.33ppm in Matta Poovan (AAB). The potassium level in the corms of the genotypes varied between 1.50% in Grand Naine (AAA) and 4.84% in Champa-I (AAB). The calcium level in the corms of the genotypes varied between 0.27% in Giant Governor and 1.20% in Martaman (AAB). The magnesium level in the corms of the genotypes varied between 0.38% in Giant Governor (AAA) and 1.13% in Green Bombay (ABB). The composition state that banana corm has sufficient nutrient for promoting propagules /suckers from the mother corm.
