Abstract
Study on influence of training and nutrition on yield of tomato (Solanum
lycopersicum L.) under protected condition was taken up at HRES, Hidakal Dam
(near KRCCH, Arabhavi), Karnataka, during rabi 2017-2018. Experiment was laid
out in two Factorial CRD Design, with three levels of training and pruning treatments
and eight levels of nutrition having total 24 treatments, replicated thrice.
Significant differences were found among growth, reproductive, yield and
yield attributing characters. The treatment having two stem training system recorded
maximum number of fruits per plant, yield per plant (kg), yield per plot (kg) and yield
per hectare (t/ha), whereas single stem training system recorded maximum plant
height (cm), average fruit weight (g), TSS (°Brix), pericarp thickness (mm), fruit
length (cm), fruit girth (cm), tenderness (kg/cm2) and minimum days taken for days to
flower, days to 50 per cent flowering, days to first harvest. Among nutrition levels,
treatment N6 (75% RDF + Protein hydrolysates (1.5 g/litre) + PSB (2 kg/ha) + VAM
(2 kg/ha) recorded maximum values for all the above growth, reproductive, yield and
yield attributing characters and quality parameters.
Interaction effect of training and nutrition levels were also found significant
for the traits under study. The treatment T2N6 (Two stem + 75% RDF + Protein
hydrolysates (1.5 g/litre) + PSB (2 kg/ha) + VAM (2 kg/ha) recorded the highest
number of fruits per plant (57.42), yield per plot (61.61 kg/ha), yield per hectare
(184.83 t/ha). The maximum plant height (173.0 cm), TSS (9.85 °Brix), pericarp
thickness (9.24 mm), fruit length (7.57 cm), fruit girth (5.52 cm) and tenderness
(3.40 kg/cm2) found in T1N6 (Single stem + 75% RDF + Protein hydrolysates
(1.5 g/litre) + PSB (2 kg/ha ) + VAM (2 kg/ha).
