Low yield is crucial bottleneck for potato production in Bangladesh. The application of vermicompost may enhance the yield of potato. The experiment was consisted of two factors, i.e., Factor A: - Vermicompost level (Vm1-4): Vm1: 0 t ha-1, Vm2: 3 t ha-1, Vm3: 6 t ha-1 and Vm4: 9 t ha-1; Factor B:- Tuber size (T1-5): T1: 5-10 g, T2: 10-20 g, T3: 20-30 g, T4: 30-40 g and T5: > 40 g. The experiment was conducted in a split-plot design with three replications. Vermicompost had significant effect on most of the yield contributing parameters investigated under present study. Results revealed that yield parameters increased with increasing vermicompost level irrespective of tuber size. Among the twenty (20) treatment combinations, vermicompost at the rate of 9 t ha-1 with tuber size > 40 g produced the maximum yield (31.33 t ha-1) that was 53.53 % higher than that of control with 3273.01 $ of monetary advantage. Therefore, present study suggests that potato growers may use vermicompost for increasing yield of potato in Bangladesh. SAARC J. Agric., 19(1): 71-79 (2021)

ABSTRACT: The objective of this work was to evaluate the development and production of semi-noble garlic cultivars subjected to different bulb-seed pre-planting vernalization periods in two municipalities (Barauna and Governador Dix-sept Rosado) of the Western Mesoregion of Rio Grande do Norte State, Brazil. Therefore, two simultaneous experiments were conducted, from April to November, 2012. A complete randomized block experimental design was used with four replications. The treatments were arranged in split-plot design, with the plots consisted of cultivars (Gigante-do-Nucleo and BRS-Hozan) and subplots consisted of bulb-seed pre-planting vernalization (4±1°C) periods (0, 10, 20 and 30 days). In Barauna, the cultivar Gigante-do-Nucleo proved to be adapted, with a yield of 4.56 Mg ha-1 without vernalization, while the BRS-Hozan presented a yield of 4.42 Mg ha-1 when vernalizated for 10 days at pre-planting. In Governador Dix-sept Rosado, the vernalization of 10 days improved the adaptation of both cultivars, however, with no significant yield increases. The use of vernalization improved adaptation of cultivars in the planting locations, facilitating the emergence of plants, increasing plant height and number of leaves, however, not promoting significant yield increases, therefore, this technology should not be used for produce this type of garlic in this region.
