Abstract/ Executive Summary:

The experiment was conducted to assess the effect of vermicompost and tuber size on the processing quality of potato during ambient storage conditions. The experiment was conducted in a split-plot design, where vermicompost levels were assigned to main plots and tuber size to subplots. The experiment was conducted at the agronomy research field of Sher-e-Bangla Agricultural University, during the period from November 1, 2014, to April 30, 2015, and November 1, 2015 to April 30, 2016 in Rabi season. The experiment has consisted of two factors, i.e., factor A:- Vermicompost level (Vm-4): Vm₁: 0 t ha-1 (Control), Vm₂: 3 t ha^-1, Vm₃: 6 t ha^-1 and Vm₄: 9 t ha^-1; factor B:- Tuber size (T-5): T₁: 5-10 g, T₂: 10-20 g, T₃: 20-30 g, T₄: 30-40 g and T₅: >40 g. After harvesting, the potato was collected and stored at ambient conditions for laboratory analysis. The research showed that vermicompost had a significant effect on most of the storage parameters. Results also showed that storage quality 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 showed the highest firmness (44.349 N), specific gravity (1.084 g cm-3), dry matter (22.77%), flesh color (L*- 75.60; a*- 11.76; b*- 24.96). In respect of ambient storage condition; weight loss increased with increasing storage time, while firmness, specific gravity, dry matter, flesh color decreased with increasing storage time. Quality parameters slowly decreased with increasing storage time up to 40 days after storage (DAS) and thereafter sharply decreased and finally became non-suitable both for table and processing purposes. Therefore, the experiment showed that potato growers may use a higher dose of vermicompost for improving the processing quality of potato and can store potato up to 40 DAS at ambient conditions.

Objectives:

To assess the effect of vermicompost and tuber size on processing quality of potato during ambient storage conditions.

Methodology:

The experiment was conducted at the agronomy research field of Sher-e-Bangla Agricultural University, during the period from November 1, 2014 to April 30, 2015 and November 1, 2015 to April 30, 2016 in the Rabi season. The experimental area was located at 23° 77' N latitude and 90° 38' E longitudes and at an altitude of 8.6 m from the sea level. The soil of the experimental area was to the general soil type series of shallow red-brown terrace soils under the Tejgaon series. Upper-level soils were clay loam in texture, olive-gray through common fine to medium distinct dark yellowish-brown mottles under the Agroecological Zone (AEZ-28) and belonged to the Madhupur Tract [23]. Soil pH was 5.6 and had organic carbon 0.45%. The experiment consisted of two factors viz., factor (a): vermicompost level (Vm1: 0 t ha^-1 (control); Vm²: 3 t ha^-1; Vm3: 6 t ha^-1; Vm4: 9 t ha^-1 ) and factor (b): seedling tuber size (S₁: 5-10 g; S₂: 10-20 g; S₃: 20-30 g; S₄: 30-40 g; S₅: >40 g). The seedling tuber of BARI TPS-1 was used for the study. The experiment was laid out in a split-plot design with 3 replications. The vermicompost was assigned to main plots and seedling tuber size to subplots. The distance between row to row was 50 cm and plant to plant distance was 25 cm. The distance from the plot to the plot was 75 cm. The size of the unit plot was 2 m × 1.5 m. So, the total number of plots was 60. 2.5 Crop Management Collected seed tubers were graded according to the size 5-10 g, 10-20 g, 20-30 g, 30-40 g, >40 g and kept at room temperature to facilitate good sprouting. Finally, sprouted potato tubers were used as planting material. The allocated plots were fertilized by recommended doses of urea 250 kg ha^-1, Triple Super Phosphate (TSP) 150 kg ha^-1, Muriate of Potash (MoP) 250 kg ha^-1, gypsum 120 kg ha^-1, Zinc sulfate 10 kg ha^-1 and boric acid 10 kg ha^-1 [25] except treatment. All the intercultural operations and plant protection measures were taken when needed. After haulm cutting the tubers were kept under the soil for 7 days for skin hardening. 2.6 Parameters Determined Data on different storage parameters were determined. The same study was conducted under the same treatment under the same field condition in both years and finally, the means were taken from these two experiments. The data obtained for different characters were statistically analyzed following the analysis of variance (ANOVA) techniques by using the Statistics 10 computer package program. The significant differences among the treatment means were compared by Least Significant Difference (LSD) at a 5% level of probability

Achievement/Findings:

From this study, it may be concluded that vermicompost is good organic manure. It plays an important role in increasing tuber quality and ambient storage performance also. From the above discussion, it was observed that Vm₄T₅ that is vermicompost level 9 t ha^-1 and tuber size >40 g showed superior processing quality that is higher firmness, specific gravity, dry matter content, and flesh color compared to those of other treatments. However, the potato farmers of Bangladesh may be potato cultivation by sing benefited for vermicompost, ultimately, they can produce high-quality potato tuber and can store without decreasing processing quality at ambient storage condition up to 40 DAS.
