Response to plant population density uri icon


  • We have often observed that the plant populations in farmers' fields are generally lower than the recommended population. Where the growth duration is long, deficiency in plant population can be partly overcome by better growth in the remaining plants. However, such a response may be of a low magnitude in locations where growth duration is short. The ability to partially compensate for the reduction in yield at lower plant population is termed "plasticity". Plasticity is the comparative ability of a cultivar to produce more or less stable /ields over a range of population densities. 3reeding for plasticity may be of use in stabilizing yields at the farmer level
