Leaf application of silicic acid to upland rice and corn

This study aimed to evaluate the effect of Si (stabilized silicic acid, Silamol (R)) leaf application on mineral nutrition and yield in upland rice and corn crops. The treatments were the control (without Si) and Si foliar split spraying using 2 L ha(-1) of the Silamol (R) commercial product, with 0...

Sumario:This study aimed to evaluate the effect of Si (stabilized silicic acid, Silamol (R)) leaf application on mineral nutrition and yield in upland rice and corn crops. The treatments were the control (without Si) and Si foliar split spraying using 2 L ha(-1) of the Silamol (R) commercial product, with 0.8% soluble Si as concentrated stabilized silicic acid. Silicon leaf application increased the concentrations of K, Ca and Si in rice and corn leaves, the number of panicles per m(2) of rice and the number of grains per ear of corn; accordingly, the Si leaf application provided a higher grain yield in both crops.
