    Studies on the effect of urea and neem cake coated urea on the nitrogen uptake of rice variety - triveni
    (Kerala Agricultural University, 1976) Abraham, C; Sadanandan, N; Sasidhar, V K
    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.

    Study on the comparative performance of urea and neem coated urea on the yield and yield attributes of rice variety triveni
    (Kerala Agricultural University, 1975) Abraham, C; Sadanandan, N; Sasidhar, V K
    A field experiment to study the comparative performance of urea and neem coated urea on the yield and yield attributes of rice variety-Triveni was conducted at the College of Agriculture, Vellayani, Kerala during Virrippu season of 1973. The treatments consisted of four levels of nitrogen (0), 40, 80 and 120 kg N/ha) and five methods of applications ie. (1) full basal urea (2j full basal neem coated urea (3) 75% basa! urea -I- 25% urea as top dressing (4) 75% basal urea 4- 25% neem coated urea as top dressing, and (5) 75% basal neem coated urea + 25% neem coated urea as top dressing. It was found that the number of panicles per square meter, 1000 grain weight and yield of grain and straw were increased by nitrogen application. The application of 40 kg nitrogen as neem coated urea was found to be equivalent to 80 kg nitrogen as urea as far as the yield of grain was concerned. The results showed that rieem cake can be profitably used to increase the efficiency of urea applied to wet land rice.
