“…In potato, applying irrigation at 5 cm depth with irrigation level 35 mm CPE showed the maximum mean number of leaves per stem (13.7 and 13.6) followed by the irrigation level 40 mm CPE (13.0 and 12.9), while the plants with irrigation level 25 mm CPE showed the minimum number of leaves per stem (11.3 and 10.8) in 2010-11 and 2011-12, respectively. The results are in close compliance with the findings of Islam et al (1990), who attained the significantly maximum number of compound leaves per plant (11.40) at irrigation level 40% depletion of available soil moisture in Bangladesh.…”

The experiment comprising four levels of irrigation (25, 30, 35 and 40 mm CPE) and four levels of potash (0, 100, 125 and 150 kg/ha) was conducted in Haryana Agricultural University, Hisar during winter season of 2010-11 and 2011-12 to find out the optimum level of irrigation and potash for better growth and yield of potato. The potato variety used for the investigation was Kufri Bahar. The treatments were laid out in a split plot design with three replications keeping a net plot size of 3.6x3.6 m. The plant height at 45, 60, 75 and 90 days after planting, number of leaves per stem, leaves weight per hill, stem weight per hill, leaf area index and total and marketable tuber yield were significantly high with irrigation level 35 mm CPE and potash @ 150 kg/ha. The two years results suggest that the irrigation level 35 mm CPE in combination with potash @ 150 kg/ha has shown the best treatment combination for potato production under semiarid conditions of Hisar (Haryna).

“…The lower IWUE achieved by the SWB treatment can probably be explained by occasional over irrigation, as explained above. IWUE values obtained for all treatments are substantially lower as compared to the results obtained by other researchers (Islam et al, 1990;Onder et al, 2005). Onder et al (2005) evaluated IWUE of potatoes under two irrigation regimes and obtained values that ranged from 66 to 114 kg ha -1 mm -1 .…”

“…Onder et al (2005) evaluated IWUE of potatoes under two irrigation regimes and obtained values that ranged from 66 to 114 kg ha -1 mm -1 . Similarly, Islam et al (1990) evaluated potato water use efficiency. The low IWUEs recorded for this experiment could probably be attributed to the overall low irrigation efficiency of furrow flood irrigation, which is usually around 60%.…”

Traditional irrigation schemes constitute about 40% of the total irrigated land in Ethiopia. Despite this, the sector has been overlooked and not supported by improved water management technologies. A survey conducted on one of the schemes, Godino, indicated that farmers apply the same amount of water regardless of crop type and growth stage. In view of this, an experiment was established at the Debre-Zeit Research Centre in Ethiopia with the objective of comparing the performance of two traditional irrigation management practices to two scientific scheduling methods namely an Irrigation Calendar generated with the Soil Water Balance (SWB) model and a neutron probe (NP) based scheduling method. The four irrigation regimes were applied to furrow irrigated potatoes. Plant sampling for dry mass determination was undertaken on a weekly basis. Results of leaf, canopy and total dry matter, as well as fresh tuber yields, indicated that the NP and SWB schedules were superior to the traditional scheduling methods. Leaf dry matter was the most responsive parameter to irrigation treatments. The overall results revealed that traditional irrigation practices did not meet the full potato crop water requirements to ensure acceptable yield, which emphasized the need for introducing better and more efficient practices. Since the best performing treatment, NP, is capital and skills intensive, site specific SWB calendars, which performed similarly to NP and are simpler to use, are to be recommended for farmers at the Godino scheme.

“…As irrigações foram realizadas quando a umidade do solo atingia o valor limite médio de 26,2%, representando um consumo médio de aproximadamente 20% da água disponível do solo, portanto em condição de umidade favorável, visando alcançar a produtividade máxima (Islam et al, 1990;Steyn et al, 1992).…”

RESUMOO presente estudo objetivou avaliar o comportamento da cultivar de batata (Solanum tuberosum L.) Monalisa, submetida a déficit hídrico em diferentes estádios fenológicos. O experimento foi conduzido em condições de campo, no município de Piracicaba, SP. Adotou-se o delineamento experimental de blocos ao acaso, com oito tratamentos e quatro repetições; os tratamentos consistiram na indução de déficit hídrico em um ou mais estádios fenológicos e foram iniciados 15 dias após a emergência da cultura. O estádio de tuberização foi o mais sensível ao déficit hídrico, ocorrido apenas neste, com redução da produtividade de 48,7% em relação à testemunha. A deficiência hídrica aplicada seqüencialmente nos estádios de tuberização e enchimento de tubérculos provocou redução acentuada na produtividade (65,4%) e, quando aplicada nos três estádios, causou drástica redução na produtividade (70,5%) em relação à testemunha. O déficit hídrico afetou também o tratamento e o número de tubérculos por planta. Palavras-chave: Solanum tuberosum, evapotranspiração, balanço hídrico WATER DEFICIT AT VARIOUS STAGES OF DEVELOPMENT OF THE POTATO ABSTRACTResearch was conducted under field conditions in the Piracicaba, SP, Brazil, to evaluate potato (Solanum tuberosum L.) "Monalisa" subjected to water deficit at different development stages. The experimental design consisted of completely randomized blocks, with eight treatments and four replications. Treatments consisted i of applying water stress at one or more development stages, starting 15 days after emergancy. Tuber formation stage, the most sensible one to water stress, had a 48.7% yield reduction in relation to the control. Water stress applied to the stages of, tuber initiation and tuber filling provided a sharp (65.4%) yield reduction. When applied to the three stages, water stress provided a drastic (70.5%) yield reduction. Water deficit also affected the number of tubers per plant and the tuber sizes.Key words: Solanum tuberosum, evapotranspiration, water balance INTRODUÇÃOA produção eficiente e altos rendimentos de uma espécie vegetal dependem, além do potencial genético, das condições climáticas e edáficas. Referente às condições climáticas, a disponibilidade hídrica tem efeito sobre a cultura, pois a falta d'água pode afetar tanto o desenvolvimento e o crescimento quanto a produtividade e a qualidade da produção; entretanto, o conhecimento apenas da necessidade total d'água pela cultura não implica num eficiente manejo da irrigação, sendo
