Nutrient Management for Cucumber

IPNI-2013-CHN-SC21

The project tested the response of cucumber to Ca and Mg in combination with N, P and K rates within the well-managed vegetable production area near Penzhou city, Sichuan. The optimal rates for N and P were adjusted downward to 210 kg N/ha and 105 kg P2O5/ha, based on the responses of cucumber to different fertilizer treatments in 2013. Read more

Interpretive Summary

2014

The project tested the response of cucumber to Ca and Mg in combination with N, P and K rates within the well-managed vegetable production area near Penzhou city, Sichuan. The optimal rates for N and P were adjusted downward to 210 kg N/ha and 105 kg P2O5/ha, based on the responses of cucumber to different fertilizer treatments in 2013.

2013

A field experiment was carried out to test the response of cucumber to macro- and secondary-nutrients in well-managed vegetable fields in Penzhou City, Sichuan Province. The experiment consisted of seven treatments, including the optimal treatment (OPT, 270-120-360 kg N-P2O5-K2O/ha), OPT-N, OPT-P, OPT-K, OPT+1/2K, OPT-1/2K, and OPT+CaMg (750 kg Ca(OH)2+300 kg MgSO4/ha). Nitrogen was used as urea (46% N), P as SSP (12% P2O5) and K as KCl (60% K2O).
