Abstract
A field experiment was conducted on “effect of integrated nutrient
management on growth, flower yield and quality of marigold (Tagetes erecta L.)
cv. arka bangara.” at PG Research Block, College of Horticulture, Mojerla,
Wanaparthy, Telangana during Rabi, 2020-21.
The experiment was laid out in Factorial Randomized block design with
three replications and nine treatments viz., T1- 75% RDF + AMC (Arka Microbial
Consortium) 75%, T2- 75% RDF + AMC (Arka Microbial Consortium) 100%, T3-
75% RDF + APK (Azotobacter + PSB + KSB) 75%, T4- 75% RDF + APK
(Azotobacter + PSB + KSB) 100%, T5- 100% RDF + AMC
(Arka Microbial Consortium) 75%, T6- 100% RDF + AMC (Arka Microbial
Consortium) 100%, T7- 100% RDF + APK (Azotobacter + PSB + KSB) 75%, T8-
100% RDF + APK (Azotobacter + PSB + KSB) 100%, T9- Control.
The study revealed that significant differences were recorded in Marigold.
Among the growth paramers, The interaction of F2B2 recorded maximum plant
height (91.35 cm) whereas, minimum plant height (84.46 cm) was found in F1B1
at 30, 60 and 90 DAT. Interaction of F2B2 recorded maximum plant spread E-W
and N-S respectively (44.23 and 43.89). however, minimum plant spread E-W and
N-S respectively (37.92) were recorded in interaction of F1B3 at 30, 60 and 90
DAT. Significantly, highest number of branches per plant (13.45) were found in
F2B2 however, lowest number of branches per plant (7.80) per plant in F1B3 at final
harvest.
Among different flowering parameters, minimum number of days were
recorded in flower bud initiation in F2B2 (29.22) whereas, maximum days were
observed in interaction of F1B3 (38.43). Minimum number of days recorded in Days
taken for 50% flowering (56.73) in F2B2 and maximum days (67.96) were recorded
in interaction of F1B3. Maximum number of fully opened flowers/plant recorded
(15.75) in interaction of F2B2. whereas, F1B3 recorded (7.54) minimum number of
fully opened flowers/plant. Minimum days taken for full bloom (81.41 days) was
found in interaction of F2B2 and maximum (89.24 days) in F1B3. Maximum flower
yield per hectare (20.69 t/ha) observed in interaction of F2B2 and minimum (11.93
t/ha) flower yield per hectare in F1B3. Significantly, maximum fresh weight of
flowers (9.93 g) was recorded in interaction of F2B2 and minimum fresh weight of
flowers (3.87 g) in F1B3.
Among different flower quality parameters, Maximum duration of
flowering (56.67 days) was recorded in interaction of F2B2 and minimum duration
of flowering (45.37 days) in interaction of F1B3. Significantly, maximum flower
longevity on plant (8.32 days) was found in F2B2 and minimum (2.67 days) flower
longevity on plant in F1B3. Maximum moisture content recorded (75.09 %) in
interaction of F2B2. whereas, F1B3 recorded (64.52 %) minimum moisture content.
Significantly, maximum shelf life of flowers (10.03 days) was recorded in
interaction of F2B2 and minimum fresh weight of flowers (3.68 days) in F1B3.
The data on the economics of effect of integrated nutrient management on
growth, flower yield and quality of marigold revealed that, T6 - 100% RDF
combination with AMC (Arka Microbial Consortium) @100% recorded the
highest benefit cost ratio (2.90) over other treatments.
Based on results, T6 - 100% RDF combination with AMC (Arka Microbial
Consortium) @100% proved to be the best treatment to improve growth, flower
yield and quality parameters of Marigold
