Abstract EN
Potassium humate (K-humate) is a promising natural resource to improve yield and nutrient uptake by crops.
A field experiment was conducted to assess the efficacy of K-humate application in combination with chemical fertilizers on enhancing yield and nutrient uptake of maize grown in a calcareous soil, western of Nile Delta, Egypt in two successive summer seasons (2015 and 2016).
The K-humate was applied at a rate of 15 kg ha-1 along with an increasing rate of chemical N, P and K fertilizers, varying from 0 to 125% of the recommended dose.
The results indicated that grain yield of maize significantly responded to application of K-humate.
The results also indicated that the computed optimum grain yield of 7463 kg ha-1 without application of K-humate can be obtained by applying 98% of the recommended dose of chemical fertilizers.
However, in the presence of K-humate, the optimum yield of 8310 kg ha-1 can be obtained by applying about 73% of the recommended dose of fertilizers.
Nutrients uptake responded linearly to the increasing rates of chemical fertilizers, without or with K-humate application.
However, the rate of increase in the presence of K-humate was substantially higher than that recorded at its absence.
The difference in the increase of nutrients uptake was the highest for P, then N and K in the presence of K-humate.
This study suggests that K-humate has the potential to increase crop yield, nutrient uptake and reduce the amounts of applied chemical fertilizers in calcareous soils.
