Studies on the effect of potassium on the growth, yield and nutrient uptake of two newly introduced rice varieties (Tainan 3 and Taichung Native I)

Abstract

A pot culture study was carried out at the Agricultural College & Research Institute, Vellayani, to determine the influence of potassium on the growth and yield characters of two varieties of rice recently introduced into Kerala, viz., Tainan 3 and Taichung Native 1. The uptake of major nutrients by the two strains was also assessed. The experiment was laid out in randomised block design with 8 treatments and 3 replications. The levels of potash applied were 0, 40, 80 and 120 kg K20/ha.
