The socio-economic information on variety development and abiotic stresses of potato cultivation at farm level are scarce in Bangladesh. Therefore, an attempt was made to assess farmers' perceptions about variety development and different abiotic stresses on potato cultivation. Primary data were collected from 240 potato farmers of Bogra and Chittagong district. The study revealed that Granula, Cardinal, and Lalpakri were the most preferred potato varieties in Bogra, while Diamant and Dohazari were the dominant varieties in Chittagong. Most farmers (70.87%) believe that the current potato yield (21.5-22.67 t/ha) can be further increased through introducing new HYVs. Drought and heat were two important limiting factors towards achieving the higher levels of potato yield. High yielding ability was considered as the most desirable varietal character and this was opined by almost 92.1% respondents, followed by drought resistant (61.13%), proper late blight control (58.75%), availability of adequate fund (57.77%), heat tolerant (53.60%), early maturity (61.5%), and good demand (44.5%) for HYV potatoes, whereas good test (81.7%), higher price (69.6%) and good storability (65.2%) were reported for local varieties. Low yield, susceptible to diseases, late maturity and low demand were the reasons for abandoning some potato varieties in the past. Dohazari variety for Chittagong and Lalpakri for Bogra have higher levels of tolerance against abiotic stresses. Finally, early maturity followed by drought tolerance, heat tolerance, and salinity tolerance were important attributes farmers wanted in new potato varieties.
An attempt was made to introduce potato (Solanum tuberosum L.) in hot arid water scarce zone of Western Rajasthan, India. Eight CIP-bred potato clones were evaluated along with two controls, viz. Kufri Pukhraj and Kufri Surya on farmer’s field at Jodhpur, Rajasthan under normal and moderate water stress regime during three winter crop seasons (2012-15). Pooled analysis revealed that CIP clone 397006.18 (34.0 tonnes/ha) out yielded Kufri Pukhraj (26.8 tonnes/ha) and Kufri Surya (20.2 tonnes/ha) for marketable tuber yield. This clone maintained yield under normal and deficit irrigation and attained 26.9% higher marketable yield under normal irrigations, which further improved by 31.3% under deficit water stress regime over the best control Kufri Pukhraj. This clone recorded highest tuber dry matter content (22.7%), statistically superior to both control Kufri Pukhraj (17.9%) and Kufri Surya (21.4%). Clone 397006.18 had highest mean drought tolerance index value (1.16) and least total weight loss under normal irrigation (4.9%) and water stress conditions (8.6%) up to 60 days of storage. Preference yield analysis by potato growers showed that they liked this clone most and its overall acceptability was fairly better for all organoleptic traits. Results of field study and participatory varietal selection indicated that clone 397006.18 performed better for tuber productivity under deficit water management, exhibited drought tolerance traits and achieved overall acceptance by the farmers in Western Rajasthan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
