A field study was carried out on potato (Solanum tuberosum L.) variety Desiree to determine the effect of seed tuber size on growth and yield performance in Dadeldhura district in 2023. The experiment was carried out in randomized complete block design (RCBD) using four replications and five treatments. Treatments used were different weighed seed tubers viz.T1:(11-20g),T2:(21-30g), T3:(31-40g), T4:(41-50g), and T5:(51-60g) . The results showed significant effect of the size of seed tubers on the growth and yield of potato. The treatment 51-60g seed tuber proved to be superior in terms of plant height, number of leaves/plant and tuber weight/hill followed by the treatment 31-40g seed tuber. Similarly, at harvest, 31-40g seed tubers yielded maximum number of tubers/hill, number of tuber/m2, total yield, total marketable yield, and average number of stem/hill followed by the treatments 51-60g and 21-30g seed tubers respectively. On the basis of potato tuber grading 21-30g seed tuber yielded bigger sized potato tubers followed by 31-40g and 51-60g respectively. The treatment 31-40g proved to be the best among all the treatments in yielding maximum total yield, total marketable yield and less number of unmarketable tubers. Similarly, the benefit cost ratio obtained from 31-40g seed tuber is significantly higher (3.82) than all other treatments. Hence, 31-40g seed tuber is suggested to farmers for profitable production of potato.

“…The main objective of initial potato seed production is obtaining medium-sized minitubers with good health status. Radouani et al [8] and Ozkaynak et al [9] indicated that the size of minitubers may range from 5 to 25 mm. Nevertheless, the size would be affected by the number of minitubers, planting density [10], growing medium [11], and especially nutrient uptake [8].…”

Seed potato production often relies on mineral fertilizers. However, biofertilizers offer an eco-friendly, cost-effective means to enhance nutrient uptake, plant growth, yields, and quality while bolstering stress resilience. Two cultivars (‘Spunta’ and ‘Russet’), two in vitro materials as microtubers and plantlets, and four bio-fertilizers were used to produce seed minitubers. These bio-fertilizers included mycorrhiza (T2), microalgae (T3), beneficial bacteria (PGPR) (T4), and vermicompost (T5). Treatment T1, which received 100% mineral nutrients, was used as the control, while the bio-fertilizers were given 40% of the mineral nutrition relative to the control. The study clearly demonstrated the effectiveness of the biofertilizers used in improving plant growth parameters, particularly highlighting the efficacy of vermicompost. The highest seed tuber yield of 173.12 g was obtained from the combination of ‘Spunta’ + microtuber + vermicompost’. In both varieties, in vitro microtubers led to a higher seed yield than in vitro plantlets. In terms of tuber diameter, tuber weight, and tuber number, the performance of the ‘Spunta’ cultivar was significantly higher than that of the ‘Russet’ cultivar. Seed tubers derived from in vitro microtubers had a larger diameter and were heavier than those derived from in vitro plantlets. However, seed tubers produced from in vitro plantlets were of a smaller size but more in number. In in vitro potato seed tuber production, we recommend the use of ‘Spunta’ cultivar and in vitro microtuber, supplementing with vermicompost to enhance yield, size, number curbing costs, and eco-friendliness.

The aim of the research was to grow potato mini-tubers in two crop rotations of protected ground using micro-plants and micro-tubers in vitro as planting material. The experiments were carried out in 2019-2021 in the Republic of North OssetiaAlania (the North Caucasus). The initial in vitro material was planted in spring (April-June) and summer (August-October) rotations in 5 L pots filled with peat substrate. The pots were placed in polycarbonate-lined greenhouses. The objects for the research were the potato varieties Gulliver, Sadon and Kumach. Microplants (control), standard (> 9 mm) and non-standard (5-9 mm) micro-tubers were used as variants for laying the experiment. According to the results of biometric observations in the period from sprouting to the plants reaching 20 cm, the presence of unevenness in plant height was noted in the variants with the use of micro-tubers. In the spring rotation, the cultivation of mini-tubers from microplants contributed to the formation of 6.9-8.0 pcs/plant with a standard fraction yield of 6.1-7.2 pcs. Productivity in variants with planting micro-tubers of 5-9 mm in size decreased by 1.6-1.9 times compared with micro-plants. In the summer rotation, the plants formed from 3.5 to 6.5 minitubers with a standard seed fraction yield of 53-72 %. Microtubers > 9mm (potato varieties: Gulliver and Kumach) in summer planting were more productive than micro-plants. On average, they formed 6.1-6.7 pcs/plant, which exceeded the control variant by 0.8-2.1 pcs. According to the results of the research, the total number of formed mini-tubers during summer rotation was 1.2-1.4 times lower than during spring rotation. The use of two rotations in the process of growing mini-tubers in protected ground contributed to an increase in the quantitative yield of produced seed material for the growing season by 1.7 times.
