ABSTRACT
The present study entitled, “Effect of planting dates and training systems on seed yield and quality in
tomato (Solanum lycopersicum L.) grown under protected conditions” was carried out inside a plastic
greenhouse at Khaltoo experimental farm using cv. Solan Lalima. The experiment was laid out in RCBD
(factorial) with sixteen treatments and three replications inside the greenhouse and in CRD (factorial) with four
replications in laboratory of department of Seed Science and Technology, Dr Y S Parmar University of
Horticulture and Forestry, Nauni, Solan (HP) during the year 2019-20. The treatments comprised of four planting
dates viz., M1 (transplanting on 1st April), M2 (transplanting on 15th April), M3 (transplanting on 1st May) and M4
(transplanting on 15th May) and four training systems viz., S1 (single stem), S2 (two stem), S3 (four stem) and S4
(no training). The observations were recorded in the greenhouse on fruit/seed yield traits like plant height (cm),
days to first flowering, no. of flower clusters per plant, no. of flowers per cluster, no. of fruits per cluster, fruit set
per cent (%), total no. of fruits per plant, average fruit weight (g), fruit yield (kg/plant, kg/m2 and q/ha), days to
red ripe fruit maturity, no. of seeds per fruit, seed yield (g/plant, g/m2 and kg/ha) and on seed quality traits
viz.,1000 seed weight (g), germination (%), seedling length (cm), seedling dry weight (mg), SVI-I (length), SVIII
(mass), seed electrical conductivity (μS/cm), cold test and accelerated aging test in the laboratory. From the
present study, it was concluded that combination M1S2 (transplanting on 1st April and two stem training system)
was significantly superior or at par with the best treatment for most of the fruit yield, seed yield and seed quality
traits like number of flowers per cluster (5.88), number of fruits per cluster (4.60), fruit set per cent (77.02 %),
total number of fruits per plant (33.40), average fruit weight (77.4 g), fruit yield (2.24 kg/plant, 13.46 kg/m2 and
717.87 q/ha, respectively), number of seeds per fruit (82.23), 1000 seed weight (3.91 g), seed yield (4.53 g/plant,
27.16 g/m2 and 217.30 kg/ha, respectively), germination (89.25%), seedling length (19.01 cm), seedling dry
weight (1.77 mg), seed vigour index-I (1696.47) seed vigour index-II (158.10), cold test (76.75 %) and
accelerated aging test (75.50 %), respectively. Hence, combination M1S2 (transplanting on 1st April and two stem
training system) was proved best for getting higher quality fresh fruit and quality seed produce and can be
recommended after multilocation testing for growing tomato under protected conditions on commercial scale.
