Field experiments were conducted in the farmer's field during Dec. 2013 to March 2014 to assess the impacts of different fertigation and mulching levels on weed control, soil temperature and yield parameters of tomato. The weed and fruit yield parameters were studied under plastic mulch and no-mulched treatments at different levels of fertigation in a FRB Design with 9 treatments and three replicates. Temperature was measured at 10 am, 1 pm and 4 pm. Temperature under mulches was higher than that of the control plots for all the times. The 25 µ thickness black plastic mulch produced higher soil temperatures than 50 µ thickness mulch. A maximum of 85 numbers of fruits were obtained for the treatment T3 i.e., 25 µ thickness and 120% RDF followed by T2. The highest yield was recorded in T3 (105.60 t ha-1) i.e., in 25 µ thickness plastic mulching at 120% RDF followed by T2 and T6 (102.95 t ha-1) and (101.51 t ha-1) respectively and lowest yield was recorded in T7 (52.41t.ha-1) i.e., control. The maximum fruit diameter of 7.23 cm was recorded in T3 followed by T2, 6.62 cm, whereas the control treatments fruits has less diameter of 5.1 cm. Weeding was done 3 times during the crop period at 30, 60 and 90 DAT. During weeding weed types, number of weeds present in the plots and the dry weight of weeds were recorded. In all mulching treatments weeds were completely absent.
