Olw‘okubeeranga kirime ky‘amugaso, okulima obutungulu kukosedwa emitendera emibi egiyitibwaamu ekiretede okukendeera mu makungula g‘obutale.
Okulonda ekifo, obutungulu bwagala ettaka eriyina obugimu era nga lirinaanye ekifo awali amazzi ag‘okufukirira. Okuteekateeka ettaka: Lino liyina okubeeranga liri 1.2 m*10*0.3 m mubuwanvu era nga ligimu bulungi. Simba obutungulu mu ttaka eririmu amazzi agamala era nga weriri waliwo obunyogovu okusinziira kukika ky‘abwo. Osimba obungi bw‘obutungulu bwa 5 – 8 kg/ ha nga osimbye buterevu mu nimiro ne 3-5 kg/ ha nga osimbuliza.
Okusiga n‘okusimba
Siga ensigo mu merezo eri awali ekisiikirize era oziwe omusana oluvanyuma lw‘okumeruka mu naku kumi nga tonaba kusimbuliza: Simbuliza nga obutungulu buli 10-15 cm mubuwanvu mu mabanga ga 25*8 cm era mubuwanvu bw‘omuttaka bwa 3 cm era fukirira bulijjo. Buterevu simba endokwa mu mabanga ga 25*8 cm.
Okukozesa ebigimusa. Teekamu obungi bwa 25-30 t/ ha obw‘ebigimusa by‘obutonte, kabala mu bungi bw‘ebigimusa bya 300kg eza ammonium sulphate, 400kg eza potassium sulphate ne 400kg eza single super phosphate oba 250 – 300kg eza NPK ku kipimo kya ratio of 15:15:15 / ha.
Ekirungo kya Sodium kiyamba mu kukula kw‘ebikoola, phosphorus ayamba mukukula kw‘emirandira era ne potassium ayamba okutangira ebirwadde
