Consequence of Organic- Inorganic Fertilizer on the Growth and Yield Performance of Tomato
An experiment was conducted at Sher-e-Bangla Agricultural University farm, Dhaka, Bangladesh during November 2011 to March 2012 to assess the consequence of organic-inorganic fertilizer on the growth and yield performance of tomato (Lycopersicon esculentum). The experiment was laid out in Randomized Complete Block Design (RCBD) with 3 replications and 9 different treatment combinations. The treatments were, T - 180 kg N/ha from Urea + 25kg P/ha from TSP + 60kg K/ha from MoP (Only inorganic); T - 155 kg N/ha from 1 2 Urea+ 25kg N/ha from Cowdung + 25kg P/ha from TSP + 60kg K/ha from MoP; T - 130 kg N/ha from Urea + 50kg 3 N/ha from Cowdung + 25kg P/ha from TSP+ 60kg K/ha from MoP; T - 105 kg N/ha from Urea + 75kg N/ha from 4 Cowdung + 25kg P/ha from TSP + 60kg K/ha from MoP; T - 80 kg N/ha from Urea + 100kg N/ha from Cowdung 5 + 25kg P/ha from TSP + 60kg K/ha from MoP; T - 55 kg N/ha from Urea + 125kg N/ha from Cowdung+ 25kg P/ha 6 from TSP + 60kg K/ha from MoP; T - 30 kg N/ha from Urea + 150kg N/ha from Cowdung + 25kg P/ha from TSP 7 + 60kg K/ha from MoP; T - 180 kg N/ha from Cowdung and T - Control. BARI Tomato-2 variety was used for 8 9 the experiment. Data were collected from different parameter. The tallest plant (67.03 cm) and maximum number of leaves per plant (98.89) was recorded from treatment T , while the shortest plant (47.50 cm) and minimum 4 number of leaves per plant (61.59) was obtained from control treatment. The highest number of fruits per plant (67.07) was obtained with treatment T and the lowest number of fruits per plant (38.51) was produced by control 5 treatment. Plant receiving N at the rate of 80 kg/ha from Urea+100 kg/ha from cowdung (T ) gave significantly 5 higher yield (77.39 t/ha). The lowest yield (44.43 t/ha) was recorded in control treatment. The highest concentration of N and P in plant was 1.63% and 0.386% which was observed in treatment T and T , 4 1 respectively. On the contrary, the lowest N (0.82%) and P (0.124%) content was found in control treatment. In case of post harvest soil, the highest total N content (0.081 %), available P (25.67 ppm) and available sulphur (14.45 ppm) was found in the treatment T T and T . The lowest total N (0.05%), available P (20.60 ppm) was 1, 4 5 found in control treatment and available sulphur (11.28 ppm) was obtained from T treatment. From the present 2 study it can be concluded that integrated application of N from both organic and inorganic sources found to be positive and significant on the growth and yield performance of tomato.
