Effect of Growth regulators and pinching on Economics with cost benefit ratio for commercial cultivation of marigold cv. Calcutta Orange

Author(s): Anuradha RW, Sateesh RP, Kulakarni BS and Shankar Meti
Abstract:
Investigation on “Effect of pinching and plant growth regulators on growth, flowering, yield and quality of African marigold (Tagetes erecta L.) cv. Calcutta Orange” was carried out during October, 2015 to February, 2016. The field experiments were carried out to find the effect of two levels of pinching i.e., no pinching and pinching and different plant growth regulators viz., GA3 at 200 ppm, NAA at 60 ppm, CCC at 1000 ppm and TIBA at 1000 ppm. Among the growth regulators, benefit cost ratio was found to be maximum in GA3 followed by NAA and CCC and minimum benefit cost ratio was found in TIBA. Among pinching, pinching had highest benefit cost ratio compared to unpinched plants, among the interactions, benefit cost ratio was found to be maximum and positive in G1P1, G2P1and minimum for control G4P0.The experiment can be concluded that pinching of apical bud and foliar spray of GA3 at 200 ppm independently gave higher yield, better quality flowers with maximum benefit in African marigold cv. Calcutta Orange.
