Abstract
A field experiment entitled “Effect of pinching and growth retardants on
growth, flowering and yield of African marigold (Tagetes erecta L.) cv. “Pusa
Narangi Gainda” was conducted at Horticulture farm, Rajasthan College of
Agriculture, Udaipur from October, 2006 to March, 2007. Twenty seventh treatment
combination consisting of three levels of pinching (no pinching, pinching at 30 DAT
and pinching at 45 DAT) and nine levels of growth retardants (i.e. three levels of each
CCC, B-9 and MH @ 500, 1000 and 1500 ppm) were laid out in Factorial
Randomized Block Design with three replications. According to the treatments
pinching was done at 30 and 45 DAT and growth retardants were sprayed twice i.e. at
30 and 45 DAT.
On the basis of present investigation it may be concluded that pinching and
growth retardants significantly affected growth, flower yield and quality of marigold.
Pertaining to the yield of flower, T15 (P1R6) treatment performed the best with the
highest yield of flower i.e., 256.52 g/plant, 4.82 kg/plot and 17.41 t/ha as compared to
the T7 (P0R7) treatment, where the lowest yield of flower (109.87 g/plant, 2.10 kg/plot
and 8.02 t/ha) was recorded.
With respect to the net return , T12 (P1R3) treatment was found superior with the
maximum net return of Rs. 1,58,762 per hectare in comparison of T1 (P0R1) treatment
in which the minimum net return of Rs.70,005 per hectare was obtained. If we
concerned upon B:C ratio then T16 (P1R7) treatment was exhibited the highest B:C
ratio of 4.921:1 while, the lowest B:C ratio (-0.699:1) was obtained with T6 (P0R6)
treatment.
