abstract={This work aims to compare the effects of basalt dust, poultry manure and NPK 20-10-10, single and combined, on the growth and yield of beetroot (<i>Beta vulgaris</i>). Thus, fieldwork was preceded by land evaluation and standard laboratory soil analysis. A randomized complete block design (RCBD) on a 172.5 m<SUP>2</SUP> experimental plot was used to investigate the effects of nine treatments: control soil (T<SUB>0</SUB>), T<SUB>1 </SUB>(5 tons ha<SUP>-1</SUP> basalt dust), T<SUB>2</SUB> (0.7 tons ha<SUP>-1</SUP> NPK 20-10-10), T<SUB>3</SUB> (20 tons ha<SUP>-1</SUP> poultry manure), T<SUB>4</SUB> (2.5 tons ha<SUP>-1</SUP> basalt dust), T<SUB>5</SUB> (0.35 tons ha<SUP>-1</SUP> NPK 20-10-10 + 10 tons ha<SUP>-1</SUP> poultry manure), T<SUB>6</SUB> (10 tons ha<SUP>-1</SUP> poultry manure + 2.5 tons ha<SUP>-1</SUP> basalt dust), T<SUB>7</SUB> (0.35 tons ha<SUP>-1</SUP> NPK 20-10-10 + 2.5 tons ha<SUP>-1</SUP> basalt dust) and T<SUB>8</SUB> (0.25 tons ha<SUP>-1</SUP> NPK 20-10-10 + 6.5 tons ha<SUP>-1</SUP> poultry manure + 2.5 tons ha<SUP>-1</SUP> basalt dust). The main results showed that land limitation was severe (N<SUB>1</SUB>), due to soil acidity, and potentially unsuitable for beetroot cultivation. The control (T<SUB>0</SUB>) was acidic (pH=4.8) but treatment raised the pH to 6.56, 6.76 and 4.91 for basalt dust, poultry manure and NPK 20-10-10, respectively. The yields were recorded in decreasing order as T<SUB>3</SUB>>T<SUB>8</SUB>> T<SUB>6</SUB>>T<SUB>5</SUB>>T<SUB>7</SUB>>T<SUB>2 </SUB>>T<SUB>4</SUB>>T<SUB>1</SUB>>T<SUB>0</SUB>. T<SUB>1</SUB> had the highest capacity to provide nutrients to soils and to balance nutrient availability to plants. T<SUB>3</SUB> alone boosted immediate productivity by improving soil acidity. The most economic treatment was T<SUB>8</SUB> suggesting a reduction in chemical fertilizer input and importation and popularization of local natural fertilizers.},
