Studies on the effect of urea and neem cake coated urea on the nitrogen uptake of rice variety - triveni

Abstract

An experiment to study the effect of urea and neem cake coated urea on the nitrogen uptake of rice variety 'Triveni' was conducted at the College of Agriculture, Vel!aya»i, Kerala during viruppu season of 1973. From the study it was found that nitrogen uptake was increased with stages of the plant. At all stages, higher levels of nitrogen increased the nitrogen uptake by the plants. At maximum tillering, panicle initiation and flowering stages, the methods of application did not influence nitrogen uptake. At harvest, the total nitrogen uptake was significantly influenced by methods of application. The split application and complete basal application of neem cake coated urea were significantly superior to application of complete basal urea.
