The widespread application of fertilizers has greatly influenced many processes and properties of agroecosystems, and agricultural fertilization is expected to increase even further in the future. To date, most research on fertilizer impacts has used short-term studies, which may be unrepresentative of long-term responses, thus hindering our capacity to predict long-term impacts. Here, we exami...

Fusarium wilt is one of the main diseases of cucumber, and bio-organic fertilizer has been used to control Fusarium wilt. In this study, a pot experiment was conducted to evaluate the effects of bio-organic fertilizer applied at four levels on the suppression of Fusarium wilt disease in cucumber, the soil physico-chemical properties and the microbial communities. In comparison with the control ...

A two-year field experiment was carried out to investigate the effects of nitrogen, composted manure, municipal waste compost, and weeds on yield and photosynthetic characteristics of corn. Experimental design was split split plot factorial with 3 replications. Main plots were weedy and weed-free, sub plots were nitrogen fertilizer levels [0 (N0) and 200 (N200) kg N ha -1 as urea], and sub sub ...

The influence of inorganic fertilizer application on the flavonoid, phenol and steroid content of the leaves of Ocimum gratissimum and Gongronema latifolium was investigated. Cultivated O. gratissimum and G. latifolium were treated with NPK (15:15:15) inorganic fertilizer at 100 kg/ha, 200 kg/ha, 300 kg/ha, 400 kg/ha and 500 kg/ha treatment levels in plastic planting buckets derived using the f...
