Abstract:
An investigation was under taken at Research Field, Department of Horticulture, Udai Pratap Collage, Affiliated to Mahatma Gandhi Kashi Vidyapith, Varanasi) India. During Rabi season of 2016-17. The experiment was laid out in randomized block design with 08 treatments, each replicated thrice. The treatments consisted of different combinations of micronutrients i.e., Boric acid, Zinc sulphate, ammonium molybdate, copper sulphate, ferrous sulphate manganes sulphate, mixture of all treatments and control also. Among 08 treatments under study, it is concluded that treatment combination of Effects of micro-nutrients on height of the plant are not very evident. However, highest length of the plant is recorded in the treatment of (T₇) mixture of all the micro-nutrients followed by Manganese sulphate. Maximum number of branches in tomato plant was recorded by the application of (T₃) Ammonium molybdate. Results pertaining to the maximum number of fruits per plant were obtained by the application of (T₅) Ferrous sulphate followed by Zinc sulphate. Fruit diameter of tomato was not affected by the application of micro-nutrients and all have more or less equal effect. Fruit yield per plant was affected by the micro-nutrient application. Highest number is recorded with the treatment of mixture of all the nutrients application followed by (T₁) Boric acid. Application of (T₃) Ammonium molebdate has beneficial effect on the T.S.S value of tomato fruit. Yield of tomato fruit per hectare was recorded in the treatment of (T₇) mixture all the Micro-nutrients (632.66 q/ha) followed by Boric acid application (557.10 q/ha) and Zinc sulphate (548.21 q/ha). Details of economic return clearly indicates the highest response ofthe treatment of mixture of all the micro-nutrient with a net profit of Rs. 180937 per hectare and C:B ratio of 1:2.05 followed by the treatment of Boric acid with net profit of Rs. 148574 per hectare and C:B ratio of 1:1.68 and Zinc sulphate with net profit of Rs. 144946 per hectare and C:B ratio of 1:1.64.
