Effect of Shading Factors and Irrigation Regimes on Cost Economics of Tomato Production under Different Shade Net House Cultivation

The experiment was conducted during Rabi seasons of Nov 2013-2014 at Dr. Annasaheb Shinde College of Agricultural Engineering and Technology, Mahatma Phule Krishi Vidyapeeth, Rahuri. To study effect of shading factors and irrigation regimes on cost economics of tomato production under different shade net house cultivation .Three different percentages of shadenet house, each of 360 m2 area, viz, 75% shading, 50% shading and 35% shading were performed by conducting the field experiments under different shadenet house and open field at the Instructional Farm of Department of Irrigation and Drainage Engineering, Dr. Annasaheb Shinde College of Agricultural Engineering and Technology, Mahatma Phule Krishi Vidyapeeth, Rahuri during rabi seasons of Nov 2013-14. The control of experiment i.e, 0% shading (no shading) was conducted in open field of 360 m2 area. Green colour shadenet houses were used for the experiments. Under Shadenet house, the maximum gross income was found due to T1 (75% x 0.95 ETc) treatment i.e. ₹ 2, 54,551/- followed by T2 (75% x 0.75 ETc) treatment i.e. ₹ 2, 52,369/-. The maximum net income was due to the treatment T1 (75% x 0.95 ETc) i.e. ₹ 1, 62,885/- followed by T2 (75% x 0.75 ETc) i.e. ₹ 1, 60,703/-. The average maximum B: C ratio (₹ 2.77) was due to T1 (75% x 0.95 ETc) under shadenet house cultivation. These experiments state that the best practice found in different environmental conditions (75% of shadenet house) can be adopted for maximum economic returns from tomato cultivation. 75% of shadenet house tomato cultivation was found best alternative tomato cultivation during rabi season to obtain maximum yield, net return and benefit: cost ratio.
