Melissa Brown NCSU Libraries Repository (North Carolina State University Libraries) 2004
Other claims from this paper (19)
- Intervention effect Soybean meal increased nutrient level and yield of broccoli in 2002.
- Intervention effect Soybean meal treatments did not affect lettuce yield, which the authors attribute to earlier crops having exhausted the fertilizer.
- Intervention effect Transplanting peppers one day after soybean meal application caused fertilizer burn to pepper roots in 2002.
- Intervention effect Peppers planted one week after soybean meal application were not harmed in 2003.
- Intervention effect Foliar sprays of seaweed, fish and fertilizer products did not affect plant nutrient levels or yields in sweet peppers, broccoli or lettuce.
- Intervention effect Incorporated soybean meal at 1093 kg/ha increased shoot weight of vegetables by 20% relative to the unfertilized control.
- Intervention effect Incorporated soybean meal at 2186 kg/ha increased shoot weight of vegetables by 10% relative to the unfertilized control.
- Intervention effect Surface-applied soybean meal at 1093 kg/ha reduced shoot weight of vegetables by 6%.
- Intervention effect Surface-applied soybean meal at 2186 kg/ha reduced shoot weight of vegetables by 18%.
- Intervention effect Surface-applied soybean meal reduced shoot weight more in small seeded vegetables than in large seeded vegetables at all rates.
- Intervention effect Incorporated soybean meal at 3279 kg/ha reduced shoot weight of small seeded vegetables by 8%.
- Intervention effect Incorporated soybean meal at 4372 kg/ha reduced shoot weight of small seeded vegetables by 46%.
- Association EC and pH of the growing media increased with soybean meal rate and were greater with surface-applied than incorporated soybean meal.
- Recommendation Small seeded vegetables should not be surface fertilized with SBM or sown directly into soil where SBM was recently incorporated.
- Recommendation Soybean meal incorporated at low rates could be a useful fertilizer for large seeded crops without inhibition.
- Intervention effect Peppers planted into the high soybean meal rate less than one week after incorporation had initially inhibited growth.
- Intervention effect By the end of the season, peppers grown with the high soybean meal rate had a biomass greater than the unfertilized control.
- Intervention effect Peppers fertilized with the low soybean meal rate did not suffer an initial inhibition.
- Intervention effect Peppers fertilized with the low soybean meal rate had the highest yield of marketable peppers at all planting times.
