Effect of plant growth regulators on growth and yield of Cabbage (Brassica oleraceae var. capitata)

Abstract

To study the response of foliar application of PGRs viz; GA3 and NAA with their different concentration. The Study was carried out in Randomization block design replicated trice and the treatments comprised of four levels of each PGRs namely GA3 (30,60,90 and 120 ppm) and NAA (25,50,75 and 100 ppm) along with control. Observations were recorded at 40 and 60 days after transplanting. The results revealed that all must all the parameters different significantly expect plant height at 40 DAT and stalk length at 40 & 60 DAT. GA3 – 120 ppm increase the plant spread(2073cm2 60 DAT) head diameter (19 cm), fresh weight (1399.7 g), dry weight(103.7 g), yield /plots (30.5 kg) yield/hectare (407.0 qha-1). It is also mentioned that highest B:C ratio of 1:2.83 was recorded for NAA 100 ppm which was closely followed by treatment GA3 120 ppm (2.81).
