Murakaza neza muri iki gice kivuga ku mirire y’ibiti by’ikawa. Ibiti by’ikawa bikeneye intungagihingwa zihagije kandi zitangwa ku gihe kugira ngo bikure neza, bitange umusaruro uhoraho, kandi bikomeze gutanga umusaruro mwiza. Iyo ibiti bitabona intungamubiri zihagije, bicika intege, umusaruro ukagabanuka, indwara n’udukoko bikiyongera, kandi umusaruro ukaba udahoraho buri mwaka. Ariko iyo byitaweho neza mu mirire yabyo, ibiti bikura neza, bigatanga umusaruro uhoraho kandi n’ubwiza bw’ikawa bukiyongera.
