Abstract
The present research work entitled, “Effect of growth regulators and nutrients on
performance of tomato (Solanum lycopersicum L.) hybrid Arka Rakshak” was
conducted during rabi, 2018-19 at research field of Department of Vegetable Science,
Odisha University of Agriculture and Technology, Bhubaneswar. The experiment was laid
out in Randomized Block Design (RBD) with thirteen treatments such as T1 – Control, T2-
NAA (25 ppm), T3-NAA (25 ppm)1st spray, Triacontanol (.05%EC) 2nd spray, T4-Boron
(0.2%) 1st spray, NAA (25 ppm) 2nd spray,T5-Calcium (0.5%) 1stspray, NAA (45 ppm)
2nd spray, T6-Boron (0.2%) 1st spray, Calcium(0.5%) 2nd spray, NAA (25 ppm) 3rd spray,
T7-Triacontanol (0.05%EC),T8-Boron (0.2%)1st spray, Triacontanol (0.05%EC) 2nd spray,
T9-Calcium (0.5%) 1st spray, Triacontanol (0.05%EC) 2nd spray ,T10-Boron (0.2%) 1st
spray, Calcium (0.5%) 2nd spray, Triacontanol (0.05%EC) 3rd spray ,T11-Boron (0.2%),T12-
Boron (0.2%) 1st spray, Calcium (0.5%) 2nd spray,T13-Calcium (0.5%) which were
replicated twice. The results revealed that the maximum values of morphometric characters
such as plant height (105.51 cm), number of branches per plant (9.75) and number of leaves
per plant (255.20) were recorded with foliar application of Boron (0.2%) as 1st spray,
Calcium (0.5%) as 2nd spray, Triacontanol (0.05%EC) as 3rd spray chronologically (T10 ).
Highest yield and yield attributing parameters such as fruit diameter (4.65 cm), fruit weight
(72.06 g), fruit yield per plant (4.26 kg) and yield per hectare (60.39 t) were recorded with
foliar application of Boron (0.2%) as 1st spray, Calcium (0.5%) as 2nd spray, Triacontanol
(0.05%EC) as 3rd spray chronologically (T10 ) . Similarly highest benefit-cost ratio of (6.22)
was observed with foliar application of Boron (0.2%) as 1st spray, Calcium (0.5%) as 2nd
spray, Triacontanol (0.05%EC) as 3rd spray chronologically (T10). Whereas the highest
yield attributing parameters such as flowers per cluster (9.1), fruit per cluster (8.0) and fruit
per plant (59.07) were recorded with foliar application of Boron (0.2%) as 1st spray,
Calcium (0.5%) as 2nd spray, NAA (25 ppm) as 3rd spray consecutively (T6). Thus, in this
experiment it was observed that foliar application of Boron (0.2%) 1st spray, Calcium
(0.5%) 2nd spray, Triacontanol (0.05%EC) 3rd spray consecutively produced better plant
height (105.51 cm), maximum number of leaves per plant (255.20), highest fruit diameter
(4.65 cm), highest fruit weight (72.06 g), highest yield per hectare (60.39 t) and highest
benefit-cost ratio of (2.40) as compared to other treatments in Arka Rakshak hybrid variety
of tomato released from IIHR.
