Effect of GA3 and kinetin on growth, yield and quality of sprouting broccoli (BRASSICA OLERACEA var. italica)

Abstract

A field experiment was carried out during the winter season of 2009 to 2010 on sprouting broccoli
cultivar Palam Samridhi at Horticultural Research Centre and Department of Horticulture, H.N.B Garhwal
University, Srinagar (Garhwal) Uttarakhand, India. 4 weeks old seedlings were treated before
transplanting by dipping their roots for 24 h in different concentration of GA3 (gibberellic acid), kinetin
and their combinations solutions. The GA3, kinetin and their combination significantly influenced the
growth performance, yield and quality characters of sprouting broccoli. GA3 30 mg L-1
+ kinetin 30 mg
L
-1
treatment gave maximum growth and yield of sprouting broccoli whereas, highest vitamin A content
found with 40 mg L-1
GA3 and vitamin C was found maximum in GA3 20 mg L-1
+ kinetin 20 mg L-1
dipping.
