Abstract
Tomato is a second important vegetable crop globally which holds immense nutritional and economic value. Effective fertilization is crucial for optimizing its growth and yield, yet comparative studies on various fertilizer types remain limited. There is insufficient research comparing the impact of various organic and fortified liquid fertilizers on tomato growth and yield. This study aimed to fill this gap by evaluating their relative effectiveness. A combination of organic and inorganic liquid fertilizers was expected to enhance the tomato plants growth and yield. The experiment was conducted at the botanical garden of department of botany LCWU, Lahore. Eighteen pots were used in the experiment to investigate the effects of fertilizers on Nadir variety of tomatoes. The study involved six fertilizer treatments: T0 (control), T1 (compost), T2 (NPK 15-15-15), T3 (FLF+ Compost), T4 (FLF+ mustard cake), T5 (DAP+ urea) in a randomized complete block design (RCBD). Growth parameters such as plant height, number of leaves, days to 1st flowering, number of flowers and stem thickness were monitored. Unfortunately, due to intense heat wave and extreme temperature fluctuations in Lahore flower drop and unsuccessful fruit setting were observed. The results showed that treatments T3 and T4 that were a combination of organic and inorganic fertilizers led to highest growth in tomato plants in comparison to treatments in which organic and inorganic fertilizers were given solely.
