Abstract

The present work was carried out at the Tsukuba International Center (TBIC), Ibaraki, Japan, from May to September, 1999, in order to find out plant response to different proportions of nitrogen split application and its components involved in yield. Yumehitachi, a rice variety of Japonica type, was used with three different relations between the basal and top dressing application of a level of 90 kg N.ha-1. High grain yields were obtained using the treatments of 45 (basal) and 45 (top dressing) kg N.ha-1. In this treatment, plants were able to produce a high effective tiller and percentages of ripened grains. The highest root number of rice plants was recorded in the first 10 cm and were negatively affected by nitrogen applications but positively by tiller number.
