College of Agriculture, Vellayani during the first crop season of 2000 to
study the nutrient management of upland rice varieties in coconut
garden.
The experiment was laid out in 3 x 3 x 2 asymmetrical confounded
factorial design with 2 replications. The treatments included 2 varieties
(Swarnaprabha and Mattatriveni), three levels of nitrogen (40, 60, 80 kg
ha') and three levels of potassium (15, 30, 45 kg ha").
Results of the experiment revealed that the varieties and different
levels of nitrogen and potassium had significant influence on most of the
biometric and yield attributing characters of upland rice. Fertilizing the
crop at 80 kg N ha": and 45 kg K20 halwas found to significantly
influence the biometric and yield attributes. Among the varieties,
Mattatriveni was superior to Swarnaprabha in most of the biometric and
yield attributing characters.
The quality characters like proline content, protein content and
chlorophyll content were significantly influenced by the highest levels
of nitrogen and potassium. Mattatriveni recorded the highest protein
content and Swarnaprabha recorded the maximum proline content. The
uptake of nutrients was profoundly influenced by the different
treatments. Increased uptake of nutrients was recorded at higher levels
of nitrogen and potassium. Mattatriveni registered the highest uptake of
nutrients at all growth stages.
Increasing the levels of nitrogen and potassium increased the soil
available nutrients. Plots grown with Mattatriveni registered the highest
values for soil available nitrogen and potassium.
The results of the economic analysis revealed that BeR was
maximum with the highest levels of N (80 kg ha") and K (45 kg ha-1). The
varieties did not differ in the benefit cost ratio.
