Oil palm is one of the primary vegetable oil sources worldwide, including in Tanzania. Tanzania’s mean yield 1.6 tons per hectare, far below 6 to 8 hectare reported elsewhere. This low attributable underdeveloped, unsustainable production systems and improvements, several biotic abiotic stresses, socio-economic policy challenges that have yet be systematically documented guide large-scale production, breeding, research support. The objectives this study were appraise improvement Tanzania, focusing on constraints, opportunities, farmers’ major preferences. A participatory rural appraisal was conducted Kigoma Region, three selected districts. Data collected from 392 farmers using semi-structured questionnaires 54 focus group discussants. subjected statistical analyses discern variables their significant associations Statistical Package for Social Science (SPSS Inc., 2020). About 98.5% participant engage production. Most respondent predominantly cultivate Dura type (97.4%), followed by Tenera (50%). constraints an inadequate supply improved planting materials (reported 82.7% respondents), poor access credit (72.4%), a high cost inputs (59.4%), market (56.4%), insect pests diseases (53.6), technologies (45.4%). chi-square analysis revealed unavailability labor (X2 = 41.181; p 0.000); limited extension services 29.074; 19.582; 0.000) differed significantly across area. Additionally, lack fertilizers 14.218; 0.001); inappropriate technology knowledge gaps 10.529; 0.005); 6.621; 0.036) 58.7% number bunches plant (40.5%), early maturity (37.2%), tolerance droughts (23%) (18.9%) most preferred traits varieties. Therefore, integrative sustainable breeding enhanced yields will increase adoption newly varieties local import substitution, economic development
