Title

SIMULATION OF POTASSIUM UPTAKE BY BARBER-CUSHMAN MODEL IN CORN UNDER TILLAGE AND FARMYARD MANURE TREATMENTS

Pages

  85-98

Abstract

 The use of models can improve understanding of nutrient uptake process by plant. Even with a lack of agreement, models can be helpful in identifying the causes of divergence. This research was performed for potassium uptake prediction, in different growth stages of CORN by Cushman model and under different tillage systems and FARMYARD MANURE treatments. Tillage treatments included surface disk harrowing+two disk, harrowing as reduced tillage (15 cm plowing depth) and moldboard plowing+two disk harrowings as conventional tillage system (30 cm plowing depth). Also, three levels of 0, 30 and 60 tons per hectare FARMYARD MANURE were used as organic manure treatments. The above mentioned treatments were done in a split block design with 3 replications and under CORN cultivation for two years. The results showed, predicted potassium uptake in plant, using Cushman model, was highly correlated with measured K uptake, but was in a much lower magnitude. With manure addition, model deviation increased in observed data. Also, model deviation was lower under reduced tillage in comparison with the conventional tillage.
