Productivity of groundnut as influenced by use of seed from a crop with moisture stress history uri icon

abstract

  • In a previous experiment conducted at the ICRISAT Research Centre, Patancheru, India. groundnut (Arachis hypogaea L.) cv. Robut 33-1 was grown under moisture stress imposed at four periods of growth i.e., emergence to maturity, emergence to peg initiation, first flush of flowering to last pod set and beginning of seed filling to maturity. Seed from each of these treatments was used during the 1982 rainy season to study the influence of differences in moisture stress history on the productivityofgroundnut.Seeds from plants with moisture stress from emergence to initiation of pegs (early moisture stress) gave higher field emergence, better seedling vigour and resulted in increased pod and kernel yields over the other treatments. Useof seeds from crops grown with moisture stress from flowering to end of pod set resulted in yield reduction
