81.1% Yield Increase for Vegetables in Kenya

The results indicated that application of SumaGrow produced a consistent positive effect on plant growth and yield on both crops at each site. Higher rates of SumaGrow had a pronounced effect on vegetative growth while better effects on harvestable yield were achieved at a lower product rate of 3.8L/acre. These results support the recommendation of SumaGrow for use as a biofertilizer on horticultural crops in Kenya.kenya

Tomatoes – the best effect of SumaGrow on plant height was achieved when the product was applied at the rate of 11.4 L/ha in combination with DAP at 100kg/ha at planting. This treatment has a mean plant height of 45.42cm in treated tomato plots at flowering state, compared to 28.17cm mean plant height in untreated control plots.

Significantly greater effects on yield were achieved in plots treated with SumaGrow in combination with DAP at planting. Application of SumaGrow during planting at the rate of 3.8 L/acre in combination with 100kg per acre of DAP produced the highest fruit yield per plant (4.31kg). This is in contrast to mean weights of 2.38kg per plant in the untreated control plots and 3.70kg per plant in the grower’s standard crop nutrition practice application of 200kg/acre DAP at planting. There was an 81.1% yield increase from the control plot to the SumaGrow treated plots.
