Groundnut were mainly cultivated under rain fed condition, lack of initial seedling quality due to lower moisture conditions, it causes reduced crop yield and in sometimes it leads to crop failure. In order to overcome this problems, effective seed enhancement techniques as seed coating plays major role in maintaining the seed quality.


The controlled release of bioactive molecules namely hormones gibberellic acid (GA3) as a smart delivery system can be achieved through seed coating in groundnut by exploiting advanced nanotechnology. Infusion of active ingredients as hormones (GA3) through the seed coating formulation by nano formulation methods. At nano level it influences the effects at higher level and gives best results through controlled release of hormones without any loss.


Due to nano formulation coating in groundnut, seeds had an effective results in all the parameters viz., imbibition rate (48%), speed of germination (5.5), germination percentage (87%), seedling length (24.7 cm), vigour index (2142), hydrolysing enzymes (α-amylase 14.83 and lipase 1.481), which significantly differs from untreated seeds. Hence, it was concluded that the GA3 infused nano formulation coating at 15 ml per kilogram of seed can be used for seed quality improvement in groundnut for better seedling establishment.
