An Evaluation of different Forms of Granulated Compound Fertilisers and Micronutrients on Solanum lycopersicum var. Swaraksha

Abstract— An open field experiment was conducted at the University of Mauritius Farm to evaluate the effects of different forms of compound fertilisers and the response of incorporating micronutrients along with the compound fertilisers on the vegetative growth and yield of Solanum lycopersicum, var. ‘Swaraksha’.  Nitrogen, phosphorus and potassium being three essential plant nutrient components, play important roles in the production of Solanum lycopersicum.  Besides, micronutrients in minute amounts are also indispensable for proper plant development.  The treatments were randomly arranged in block design (RBD) with four replicates.  These were: control (T1), 13-13-20-2 complex (T2), 13-13-20-2 complex with micronutrients (T3), 13-13-20-2 blended form with micronutrient (T4) and 13-13-20-2 in compacted form (T5).  The results showed that treatment T4 had the most significant upsurge in growth and yield of Solanum lycopersicum with respect to the control block and compared to the other forms of fertilisers.  The yields were found to be 47.83 t/ha under T4 followed by 35.52 t/ha under T3. The highest number of flowers and fruits per plant were also observed in T4.  Hence, it is essential to employ these nutritive components for satisfactory growth and yield of Solanum lycopersicum while taking into consideration the costs of inputs.
