Foliar applied Speedfol® Rice SP and Ultrasol® K increase rice net income by 9 to 16%
The trial was set up in a Japonica rice field in Dandong, Liaoning province in China. The soil was medium fertile sandy loam with 42 mg exchangeable K/kg (low level), 0,7 mg available Zn/kg (low level) and 1,46 mg available B/kg soil (adequate level). All plots received equal amounts of 25 MT farmyard manure/ha, 160 kg N/ha and 69 kg P2O5/ha in the base and side dressings. The trial design consisted of a completely randomized block design with 36 plots in total: 3 soil K levels, 3 foliar treatments and 4 replicates.
Foliar applied Speedfol® Rice SP and Ultrasol® K, on top of the current standard practice of 150 kg KCL/ha in the base dressing, increased crop yield by 9 to 17% and raised the farmer's net income by 9 to 16%.
