Abstract

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)

Highlights

Potato (Solanum tuberosum L.) belongs to the Solanaceae family is cultivated in nearly 150 countries and is the world’s single most vital tuberous crop with an important role in the global food network and food security (Singh, 2010)
The total world potato production is estimated at 381,682,144 ton in 2014 (FAOSTAT, 2015)
The present study revealed that, an increased in seedling tuber size gradually increased the yield of seed tubers

Summary

Introduction

Potato (Solanum tuberosum L.) belongs to the Solanaceae family is cultivated in nearly 150 countries and is the world’s single most vital tuberous crop with an important role in the global food network and food security (Singh, 2010). It is the world’s fourth largest crop after maize, wheat and rice. The total world potato production is estimated at 381,682,144 ton in 2014 (FAOSTAT, 2015) It is the most cultivated tuber crop in the world with one third of total production harvested in densely populated developing countries, like China and India (CIP, 2008). In the world’s top 10 potato producing countries, Bangladesh ranks 7th position (FAOSTAT, 2015).
