(Unpublished).http://krishikosh.egranth.ac.in/handle/1/5810130203The experiment was laid out factorial randomized block design with three main treatments, two sub main treatment and four replications. The treatment consisted of two shadenet house and open field with mulch and without mulch viz., green shadenet house (GSH), white shadenet house (WSH) and open field (OF). The white shadenet house (WSH) was significantly increased the growth and fruit weight per plant (4.02 kg) were significantly higher under white shadenet house with mulching.A field investigation on “Effect of different colour shadenet and mulching on growth of tomato” during 01 November 2018 to 28 February 2019 was carried out at research farm of Farm Structures, College of Agricultural Engineering and Technology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.) with a view to study the effect of environmental parameters on biometric characteristics of tomato with mulching and without mulching in different colour shadenet house and open field, and to study the cost economics of tomato production with mulching and without mulching in different shadenet house and open field. In white shadenet house the average temperature, relative humidity, light intensity, soil temperature with mulch, soil temperature with non-mulch and carbon dioxide were found as 28.66 , 47.13%, 361.33 lx, 26.15 , 24.43 and 576.50 ppm respectively, In greenshadenet house the average temperature, relative humidity, light intensity, soil temperature with mulch, soil temperature with non-mulch and carbon dioxide were observed as 27.36 , 45.48%, 350.54 lx, 25.34 , 24.28 and 542.62 ppm respectively. In open field, the average temperature, relative humidity, light intensity, soil temperature with mulch, soil temperature with non-mulch and carbon dioxide were observed as 30.31 , 43.22%, 655.47 lx, 27.84 , 26.23 , and 377.25 ppm respectively. The white shadenet house with mulching was significantly increased the growth attributes viz., plant height was 130.50 cm, number of primary branches plant-I was 27.41, canopy area 2900.50 cm2 at last picking while stem diameter (18.51 mm) was significantly increased under white shadenet house. The important yield contributing characters viz., a number of fruits plant-I 62.99, fruit length 5.22 cm, and fruit weight per plant 4.02 kg were significantly higher under white shadenet house The white shadenet house without mulching was significantly increased the growth attributes viz., plant height was 112.91 cm, number of primary branches plant-I was 23.91, canopy area 2863.41 cm2 at last picking while stem diameter 17.35 mm was significantly increased under white shadenet house. The important yield contributing characters viz., a number of fruits plant-I 58.41, fruit length 4.64 cm, and fruit weight per plant 3.76 Kg were significantly higher under white shadenet house. The fruit yield of Tomato was significantly higher under white shadenet house with mulching 46.61 t/ha and it was higher than open field condition. The green shadenet house with mulching 38.51 t/ha found second best treatment for achieving the higher yield of Tomato. Among the shadenet house, the greenshadenet house observed minimum growth and yield attributes as well as fruit yield of Tomato. The open field condition was observed significantly minimum growth, yield attributes and fruit yield of Tomato with mulching 19.00 t/ha compared to different shadenet house. The fruit yield of Tomato was significantly higher under white shadenet house without mulching 42.44 t/ha and it was higher than open field condition. The green shadenet house without mulching 35.72 t/ha found the second best treatment for achieving the higher yield of Tomato. Among the shadenet house, the greenshadenet house observed minimum growth and yield attributes as well as fruit yield of Tomato. The open field condition was observed significantly minimum growth, yield attributes and fruit yield of Tomato without mulching 15.94 t/ha compared to different shadenet house The maximum and significantly higher fruit yield of Tomato was obtained under a white shadenet house with mulching was 46.61 q per 1000m2 followed by green shadenet house with mulching 38.51 q per 1000m2. On the basis of benefit cost ratio it is economically viable for the farmers to adopt white shadenet house with mulching for tomato which shows have gross return q/1000 m2 and total cost q/1000 m2 of 93220 and 40,130.15 by which we get gross return q/1000 m2 of 93,220 and B:C ratio as 2.32.ennullThesis
