Efficacy of Different Organic Manures on Growth and Yield Performance of Organically Grown Tomato

The field experiment was conducted at the Horticultural farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka -1207 during the period from October 2014 to March 2015 to find out the efficacy of different organic manures and different varieties on the growth, yield performance of organically grown tomato. The experiment comprised of two different factors: Factor A. four types of organic manure [M0= Control (No organic manures application), M1 = Cow dung (30 t.ha-1), M2 = Poultry manure (25 t.ha-1) and M3 = Vermicompost (20 t.ha-1)] Factor B. three types of variety V1 = BARI tomato 15, V2 = BARI tomato 14 and V3 = BARI tomato 2. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Encouraging responses were monitored in all respects. Among the treatment combination M2V1 (Poultry manure + BARI Tomato 15) showed the highest plant height, maximum number of flower cluster, number of flower per cluster, number of fruits per cluster and number of fruit per plant with improved fruit size. The maximum yield (86.25 t/ha) was recorded from the treatment combination of M2V1 (Poultry manure + BARI Tomato 15), while the treatment combination of M0V3 (Control treatment + BARI Tomato 2) gave the minimum yield (31.25 t/ha). Therefore, BARI Tomato 15 coupled with poultry manure can be the most suitable for enhanced yield and can be considered a noble practice in sustainable agriculture.
