Babasaheb  (64) is well known progressive and experienced farmer in the field of onion  cultivation and seed production. He has developed Sona-40variety of onion through  mass selection from N-2-4-1variety based on the criteria of healthyplants,bigger  and uniform flower size. Initiated in the year 2000, the selection process  continued till 2005, when the desired characters were stabilized. He named the  new variety- Sona-40.
This early maturing variety is known  for its bulbs with single predominant axes made from the thick ring. The red  coloured medium sized bulbs are free from splitting and have good shelf life. The variety has been validated at two locations under  Dr.Balasaheb Sawant Konkan Krishi Vidyapeeth (Dr. BSKKV), Dapoli, Maharashtra.  During the study, Sona-40 was found to be superior in terms of average bulb  weight, no. of rings per bulb, ring size, keeping quality and lower incidence  of blotch disease as compared to checks. The variety produced significantly  higher bulb yield (33 - 34 tons/ha) at both the locations over checks.
Babasaheb has received Krishi  Bhooshanaward from Maharashtra State for progressive farming and his  contribution to onion cultivation. NIF-India has supported for on-farm trials  and dissemination of the variety in twelve states and encouraging results and  feedback was received from growers of Rajasthan and Maharashtra. Over 13,600 kg  seeds of the variety has been distributed to the farmers of Gujarat, Andhra  Pradesh and Karnataka since 2016. The process of registration of the variety under  PPV & FR Act, 2001 has already been initiated by NIF-India.
