Abstract: The performance of tomato crop cultivation in open field and under shadenet
house condition was evaluated at farmers field in shahdol district. Under shade
net house condition green colour shade net having 50% shade factor was used in
the study. Same crop was cultural practices in the open field and shade net
cultivation was adopted for comparison. Irrigation facility was adopted in field
is drip irrigation and frequency of irrigation was same on both field. The
study revealed that under shade net condition performance of tomato the crop
yield was increased by 56.92 per cent, plant height was 53.37 per cent, harvest
duration was 38.86 per cent and number of harvest was 59.38 per cent over open
field cultivation.  

 

Introduction:- India is second largest vegetable producer in the
world next to China; however it’s per capita per day availability
is well below 92g whereas the recommended consumption is 284 g. Protected cultivation technologies are
being utilized all over the world but the level and extent of their use may be
different among

different countries. Agronomical practices
play an important role for obtaining higher yields especially under protected
structures. To make its cultivation successful, polyhouses and plastic-mulching
are most suitable solutions (Chandra et al., 2000; Singh et al.,
2004 and 2010). The production of off-season vegetable crops under net house
conditions was evaluated for total yield, earliness and other character and
incidence of insect pests (Cheema et al., 2004). The cultivation of
vegetables in net house can play a better role in improving quality, advancing
maturity as well as increasing fruiting span and productivity. Singh and Sirohi
(2008) examined that protected cultivation of vegetables offers distinct
advantages of quality, productivity and favourable market price to the growers.
Dixit (2007) studied the performance of leafy vegetables under protected
environment and open field condition. Protected structure offers an opportunity
for extended period of cultivation under frost free and comparatively higher
night temperature conditions. Therefore, an effort has been made to study the
performance of tomato crop cultivation in shade net house and open field
condition. Tomato (Solanum lycopersicon L.) is available throughout the year in
India. Singh and Asrey (2005) also recommended that cultivation of tomato in a
greenhouse would help obtain high productivity and better return.

Material and Methods :- The study was conducted under shade net house and
open field condition at farmers field in shahdol district. Tomato crop was
selected for this study and technical guidance was provided by krishi vigyan
Kendra shahdol. The climate of this area is hot sub humid and sandy loam soil
present in this area. The crop was 30 day after transplanted in shad net and
open field and covered cultivation at a spacing of 60 cm between plants and 30
cm between rows. Lateral line with inline drippers have 2 lph discharge was
installed for irrigation as well as fertigation of tomato crops.

Results and discussion :- The results are presented under the head (i) Plant
characteristics (ii) Yield parameter

Plant growth characteristics :- Plant growth characteristics such as plant height,
number of branches, day of first flowering, day of harvesting, total number of
harvesting, harvesting duration were measured for tomato crop under shade net
house and open field was show in table 1.  In table 1 show that plant height, number of
branches per plant, number of harvesting and harvest duration were higher for
the tomato crop cultivation in shade net over open field. The first flowering
in open field tomato was 70.38 DAT because of hot temperature in this district and
in shad net tomato crop flowering was late 79.5 DAT. Total harvest duration in
shade net house was 64.63 day and 46.75 day in open field.

Yield parameter :- Yield parameter show in table 2 in this table fruit
weight, number of fruit per plant, yield per plant, yield per plot and
productivity was measured. In shade net house fruit quality was good and fruit weight
was 60.56 g and in open field fruit quality was small as compare to shade net
condition is 40.61 g. Total numbers of fruit per plant higher (88.75) as
compare to open field (61.13) so, yield per plant was more in shade net house
tomato cultivation is 7.56 kg and open field condition is 3.99 kg. In shade net
house yield per plot was 128.95 q and in open field condition yield per plot
was 82.84 q. Tomato productivity was 412.38 q/ha in open field and 644.75 q/ha
in shade net house.

Performance improvement :- In table 3 reveals that yield per ha, number of fruit
per plant, fruit weight, plant height, harvest duration and number of harvest
were 56.92, 45.53, 50.19, 53.37, 38.86, 59.38% more respectively, under shade
net house condition compared to the open field condition. These findings
demonstrate the suitability as well as economic feasibility of shadenet house
as compare to open field condition in adverse and off session condition in
shahdol district. Therefor, it may be concluded that shadenet house are a good
and less expensive option for tomato cultivation for obtained higher yield,
number of fruit per plant and number of harvest more as compare to open field
condition in off session.
