Effect of Full, Half and Quarter Size Potato Tuber Seed on Growth and Yield of Potato (Solanum tuberosum L.)
Bibliographic record
Abstract
Potato is a crucial food and cash crop in Bangladesh, acting as a staple crop for food security due to its nutritional value, broad adaptability, and early maturity. However, the potato productivity is limited by several factors. One of the crucial limiting factors is the size of the seed tuber, which is not specified. During the period from November 2022 to February 2023, a study was carried out in the research field of the Department of Agriculture at Noakhali Science and Technology University, Bangladesh to investigate how varying tuber sizes impact the growth and yield of potatoes. The study was structured in a Randomized Complete Block Design (RCBD) with three treatments and three replications. The treatment combinations were T0 (Quarter size of potato tuber), T1 (Half size of potato tuber), T2 (Full size of potato tuber) respectively. Data was collected from various phases of plant growth and development viz, plant height, number of leaves per hill, number of stems per hill, number of tuber per plant, gross yield per hectare, unmarketable yield per hectare, marketable yield per hectare, small size tuber (%), medium size tuber (%) and large size tuber (%). The highest unmarketable yield (5.81 t ha-1), small size tuber (37.73%) and medium size tuber (40.92%) was recorded from T0 (Quarter size of potato tuber) whereas the lowest unmarketable yield (3.11 t ha-1), small size tuber (19.07%) and medium size tuber (32.92%) was obtained from the treatment T2 (Full size of potato tuber). Highest plant height (53.12 cm), number of leaves per hill (491.67), number of stems per hill (7.48), number of tuber per plant (19.66), gross yield (33.43 t ha-1), marketable yield (30.19 t ha-1) and large size tuber (48.03%) was found in treatment T2 (Full size of potato tuber) whereas lowest data recorded from treatment T0 (Quarter size of potato tuber). Observing the results, it can be stated that planting of full size of potato tuber seed for potato cultivation gave better growth, yield and yield contributing characters of potato.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
