t0“performance and yield of maize, kale and capsicum”
e0“Effect of formulated slow release NPK fertilizer [cellulose-graft-poly(acrylamide)/nanohydroxyapatite/soluble fertilizer] composite (SRF) on the performance and yield of maize, kale and capsicum was evaluated in a greenhouse experiment. No significant difference in growth parameters was observed between SRF and commercial fertilizer (CF) treatments”
e1“SRF recorded higher dry matter and yields relative to CF with similar application rates, though statistically insignificant”

Other claims from this paper (13)
- Intervention effect No significant difference in growth parameters was observed between the slow release fertilizer and commercial fertilizer in maize, kale and capsicum.
- Observation P deficiency was observed in maize at the lowest slow release fertilizer application rate of 45-57-17.
- Observation N deficiency was observed in commercial fertilizer treated plants at the 8th week.
- Observation No N deficiency was observed in slow release fertilizer treated plants at similar application rates at the 8th week.
- Observation Kale showed both N and P deficiencies in the 7th week.
- Observation Capsicum alone showed N deficiency in the 14th week under slow release fertilizer at low application rates.
- Intervention effect NPK content in maize tissues differed significantly between the amendments and the control.
- Intervention effect NPK content in kale tissues differed significantly between the amendments and the control.
- Intervention effect Capsicum tissues had significantly higher N content under slow release fertilizer at higher application rates of 125-159-45 than under the control.
- Intervention effect Capsicum tissues had significantly higher N content under commercial fertilizer at higher application rates of 100-100-100 than under the control.
- Intervention effect At final harvest, soil planted with maize and amended with the highest slow release fertilizer rate had significantly higher P content than lower rates and the control.
- Intervention effect The agronomic optimal rate of the slow release fertilizer, determined by a quadratic function, was higher than that of commercial fertilizer.
- Intervention effect The slow release fertilizer enhanced growth and yields of crops just like commercial fertilizer.
