“…A gradual decrease in tuber number was observed with a gradual increase of water stress. Present results agree with previous studies of Haverkort et al, [11], Levy [14], and Hassanpanh [9]. Tuber number is very sensitive to mild drought was also reported by Deblonde and Ladent [4].…”

“…In severe drought condition, the highest yield was observed in CIP 396244.12 (14.64 ton/ha and 13.56 ton/ha with a mean of 14.10 ton/ha) which was similar to CIP 393371.58 (14.38 ton/ha and 10.69 ton/ha with a mean of 12.53 t/ha) and the CIP 391004.18 (11.27 ton/ha and 10.36 ton/ha with a mean of 10.82 ton) was the lowest. In mild drought condition, it ranged from 21.12 to 24.38 ton/ha in 2010-11 and 17.44 to 22 [12], Hassanpanh [9]. Deblonde et al, [3] reported that severe drought treatment adversely affected tuber yield.…”

Abstract:Four CIP potato clones with 1 check variety Asterix were grown during 2010-11 and 2011-12 at Horticulture Research Farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh to observe the effect of water stress on canopy structure, yield and growth rate of potato. The study validated that all the genotypes showed reduction in plant height, number of above ground shoots per plant, tuber number per plant and yield by different degrees of drought. Significant yield reduction was found among the genotypes due to drought treatments. Genotype CIP 396244.12 and CIP 393371.58 performed better in severe drought condition in producing higher number of tuber per plant and yield. CIP 396244.12 produced the highest leaf area index in all drought treatments whereas the CIP 391004.18 produced the minimum. In all stage of growth, crop growth rate was affected by different drought treatments where CIP 396244.12 showed the highest crop growth rate followed by CIP 393371.58 and CIP 391004.18 being the lowest. Under severe and moderate drought condition genotype CIP 396244.12 maintained a higher tuber growth rate but under well watered condition CIP 396244.12 and Asterix achieved superior.

“…The low number of tubers can be explained by the fact that a drought season, lasting 42 days was recorded, with a water deficiency that is known to cause potato plants to produce less tuber number as well as fresh weight (Hassanpanah, 2010).…”

Seed-potato production through sprouts and field multiplication and cultivar performance in organic system

Organic farming requires the production or use of certified seeds from the same cultivation system and, the information of potato cultivars adapted to organic production system is important. The objective of this work was to study the feasibility of utilizing sprouts of different potato cultivars, seed multiplication and yield potential in field conditions without using agrochemicals. Three experiments were conducted: the first experiment using sprouts as seed under protected cultivation in Guarapuava, Paraná State, Brazil, from November 2011 to February 2012; the second experiment was field conducted in Candói, Paraná State, from May to September 2012 and the third experiment was field conducted in Guarapuava, Paraná State, from February to May 2013. The experimental design was a randomized block design with 3 replications in all 3 experiments. In the 2 first experiments the following cultivars were evaluated: BRS Ana, BRS Clara, BRS Eliza, Crystal and Catucha, and in the last experiment Agata, Bintje, Baronesa and BRSIPR Bel were included. The traits analyzed were length of main stem, number of stems, number of leaves, fresh weight and number of tubers, percentage of infection by viruses and in the second experiment the incidence of late blight on leaves. In the third experiment, leaf area index (LAI), tuber, leaves and stem dry weights and late blight severity were also analyzed. In the first experiment, the cultivars showed differences in plant height and minituber production, the highest value was observed in cultivars BRS Clara and BRS Ana for plant height and cultivar BRS Clara for minituber production. In the second experiment, there was difference only in plant height, the tallest cultivars were BRS Ana and BRS Clara . There was low spread of viruses and, it did not directly reflect in tuber yield. In the third experiment the cultivars with lower disease severity were those recommended to organic farming, especially BRS Clara and Catucha; this second cultivar had the higher LAI and tuber yield, as well as resistance to late blight, factors that might have contributed to the recorded highest total tuber yield (13.8 t/ha).

India, the second largest producer of potato in the world almost doubled its potato production during 2003-2013 adding additional 22.18 million tonnes and taking total production to 45.34 million tonnes (FAOSTAT). During this period of time the country increased its potato productivity by 31.4% (augmentation of 5.44 tonne/ha) (Rana, 2015). This rapid growth in potato production figures in India were largely backed by the unnoticed food security role assumed by the potato (Thiele et al. 2010, Singh and AbstractIndia has experienced rapid growth in potato production during recent past and the country has almost doubled its potato production during 2003-2013. The potato productivity improved 31.4% over this period of time. However, potato production scenario in southern states of India is quite grim and with the result potato consumers of these states always have to purchase potatoes at very high prices compared to the national average prices. With the objective to augment potato production in southern states this study was carried out for analysing socio-economic characteristics of potential potato growers in non-traditional Anantapuramu and Kurnool districts of arid region in Andhra Pradesh. A long list of socio-economic factors viz. education level, occupation pattern, house condition, tractor ownership, food security level, access and affordability to civic amenities, children's education type, possession of household amenities, expenditure pattern and level of mechanization adoption were studied in this study so that most suitable area for potato introduction may be identified.
