California Farmers Increased Harvest in Chinese Vegetables

Joyful Farms is located in Hemet, California, where 37 types of Chinese vegetables like bok choy, mustard greens, nira, etc. are grown. Aidy Yang was hired to rehabilitate the soil and he began using 5 gallons of SumaGrow on 5 acres of their Long Run field with no other inputs. On the Short Run field, Aidy would use 5 gallons on 8 acres and reduced his fertilizer inputs by one half.

On September 10th, the vegetables crops Yu Choy and Mustard Greens were planted on 8 acres on the Short Run Field. Three days later on September 13th, a weed killer (herbicide) was sprayed on the Short Run Field. Three days after the herbicide (September 16th) six gallons of EarthCare with SumaGrow was sprayed on the Short Run field. On September 17th, the amount of chemical fertilizer was reduced by one-half. About two weeks later another three gallons of SumaGrow was applied to the 8 acres, which brought the total amount of SumaGrow used to 1.123 gallons per acre.

The mustard greens shown below are a 60 day crop, but 5% of the crop were ready to be harvested 10 days early.

The fields were planted with Baby Bok Choy, Yu Choy and Mustard Greens. Organic fertilizer (chicken manure) was applied to all 15 acres at half the normal rate.

Aidy returned to the Joyful Farms on December 5th to visit the Long Run Field and he was greeted with a green carpet of crops. The workers were thrilled because there were no weeds and Joyful Farms Chinese Vegetables- Increased Harvest pic 4they had experienced a much faster harvest times on the Short Run Field and were also looking forward to harvesting the Long Run field. As you can see, the Long Run Field did very well.

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.
