| Abstract: | In an experiment to study the crop weed competition for 3 major nutrients in a short duration rice, carried out at the College of Agriculture, Vellayani, it was found that in general competition for the three nutrients N, P and K was severe between 21-40 days after transplanting. Weed removal during 21 -30 days helped the crop to absorb more of the nutrients. The demand for the nutrients was in the order of K> N> P by crop and weed. The nutrient uptake by weed was negatively correlated with crop yield while the uptake by weed and crop were also negatively correlated. |
