... BACKGROUND AND AIMS: Plastic responses to stress in components of reproduction can have important effects on plant fitness and can vary both within and between species. Responses may also depend on when in the life cycle stress occurs. Here, it is predicted that the timing of initiation of a stress, defoliation, would affect the pattern of plastic responses. These differences should occur because ...

Abstract:
... Field experiments were carried out for 3 years to assess the efficacy of organic manures (Sesbania, Leucaena, cowpea, mungbean, wheat straw and FYM) in enhancing the productivity of rice and in supplying Fe. Green manuring with Sesbania gave the highest rice yield, whereas the lowest yield was recorded with wheat straw incorporation. The concentration and uptake of Fe by rice was sig ...
