Standardisation of agro-techniques for flower quality parameters in ornamental sunflower (Helianthus annus L.)

An experiment was carried out on standardisation of agro-techniques for flower quality parameters in ornamental sunflower during 2012-13 at GKVK, campus, College of Horticulture, University of Horticultural Sciences, Bagalkot. In three way interaction effect longest stalk length (36.33) was in the t...

In three way interaction effect longest stalk length (36.33) was in the treatment combination of mulching i.e M1 (with mulch) with a spacing of S1 (60 cm x 40 cm) at the fertilizer rate F1 (40:60:40 NPK kg ha-1). Stalk girth was maximum with mulching treatment of M1 (with mulch) at a spacing of S1 (60 cm x 40 cm) with the fertilizer rate of F3 (80:90:80 NPK kg ha-1) and without mulch at the spacing of S1 (60 cm x 40 cm) with fertilizer rate of F3 (80:90:80 NPK kg ha- 1) recording 0.49 and 0.46 cm respectively. Mulching i.e M1 (with mulch) at spacing S1 (60 cm x 40 cm) with fertilizer rate if F3 (80:90:80 NPK kg ha-1) produced plants with largest flower head diameter (13.24 cm). The treatment combinations of M1 (with mulch) + S1 (60 cm x 40 cm) + F3 (80:90:80 NPK kg ha-1) 4.65 cm recorded broadest flower disc diameter. Considering the results ornamental sunflower can be grown best without mulching, at a spacing of 60 x 30 cm or 60 x 40 cm with optimum to higher fertilizer dose to give best flower quality in ornamental sunflower.Kirtimala B NaikS K NatarajD P KumarY G ShadakshariG B SeetharamuR VenugopalanK V JayaprasadSociety for Promotion of Horticulture - Indian Institute of Horticultural Researcharticleornamental sunflowermulching, spacingfertilizersqualityPlant cultureSB1-1110ENJournal of Horticultural Sciences, Vol 12, Iss 1, Pp 33-41 (2017)
