There is an urgent need to supply farmers with true-to-type grafted seedlings of shorter gestation period and direct seeds sowing of high yield. The screenhouse grafted shea seedlings, grafted shea seedlings transferred to open field and shea seeds directly sowed in nursery bags in the open field had been studied. The results revealed that scions collected from shea tree accessions in the parkland with the best agronomic traits were grafted in screenhouse at 500 per batch for each trial. After six months trial, the highest mean survival and mortality rates for grafted shea seedlings in screenhouse were 87.6 and 12.4%. Followed by the second grafted shea seedlings transferred to open field with 19.1 and 80.9 had the highest mortality rate and the third, seeds directly sowed in the open field using nursery bags 94.7 and 5.3% had the highest survival rate respectively. The average mean screenhouse temperatures at midday were 38.30C, open field 32.80C and screenhouse cooling 27.30C. The screenhouse cooling temperature was better for grafting compared with open field. The cooling was normalized by opening the doors, watering and cross ventilation to reduce plant stress. The differentiated grafted shea seedlings in screenhouse at 3 months old were transplanted to the field. However, the grafted shea seedlings raised in screenhouse exhibited better plant vigor, pest and disease free and, would have true- to-type as parent plant and shorter gestation period for quality seedlings multiplication for farmers in Nigeria
