Economics of Teak (Tectona grandis L. F.) plantation with different spacing and organic inputs in Semi-arid region of Rajasthan

A field experiment was conducted during the July 2019 to April 2020, at the Herbal Garden, College of Horticulture and Forestry, Jhalarapatan, Jhalawar. The experiment consisted of 10 treatment of different organic inputs viz.; sand, FYM and Vermicompost in different combinations and was laid out in Randomized Block Design with three replications. The study aimed to find out best treatment combination and spacing for the initial establishment of the plantations with an appropriate idea to find out its cost of cultivation for ultimate success. Although treatment T9 comprising [Vermicompost (2 kg + 1 kg + 1 kg) + FYM (2 kg + 1 kg + 1 kg)] was found significantly superior over all among treatments and then treatment T8 [Vermicompost (1 kg + 1 kg + 1 kg) + FYM (1 kg + 1 kg + 1 kg)] exhibited at par results in most of the growth parameters in Teak (Tectona grandis L. F.) plantations but both the treatments are having maximum cost of cultivation. From the experiment, it may be concluded that T9 and T8 treatments being costlier, may be considered suitable for better growth and development of Teak (Tectona grandis L. F.) plants in the soil and climatic conditions similar to Jhalawar (Semi-arid) region with Spacing S3 (5 m x 6 m) then S2 (5 m x 5 m) for plant growth and development in the first year.
