“…The data in this investigation (Table 5) and those reported by Box et a!. ( 3) and Stockton ( 18), indicate that potato yields may be lowered appreciably should the mean soil moisture tension during the growth period exceed 1.0 atm. We found that a change even from 0.5 to 0.…”

Potato plants were grown 3 different years in noncompacted, moderately compacted, and severely compacted soils. Changes in yield and quality of tubers were measured against different levels of N and P and against soil moisture tension. Total and U. S. No. 1 tuber yields were affected adversely by compacted soil. Tuber deformity was confined to angular development conforming to the shape of adjacent clods. Second growth and growth cracks in tubers were of no consequence. No consistent change in specific gravity was found. Neither yield nor quality of the tubers was enhanced by use of N higher than 180 pounds per acre. Addition of P had no appreciable effect. Soil P reserves were high. Tuber yield and quality in all soils were best when the soil moisture tension was near 0.5 atm. At a lower tension (0.2 atm) enlarged lenticels were more prevalent, and at a higher tension (0.7 atm) the yield and percent of U. S. No. 1 tubers diminished in severely compacted soil. Without proper control of the soil moisture regime in compacted soils, loss in tuber yield and quality could be accentuated. Neither changes in fertilizer nor irrigation practices alleviated the adverse effects of soil compaction on potato yield or quality.

“…1, 2, 3). High soil temperature regimes have been reported as a major cause of reduced yield and quality of potatoes (Box et al, 1963;Manrique, 1985;Yamaguchi et al, 1964). The soil temperature regime difference under each irrigation treatment was probably the cause of significantly higher yields of cull tubers for the 8inch emitter depth treatment.…”

“…The effects of soil temperature on potato growth and yield also vary with the growth stage of the crop (Epstein, 1966). When the mean maximum soil temperature exceeded 21.7C, and the soil matric potential changed from -0.037 to -0.057 MPa total tuber yield declined 6% (Box et al, 1963). Higher yield and more-uniform tubers were produced between 15 to 23C than under soil temperatures below and above this range (Yamaguchi et al, 1964).…”

A 2-year study on the influence of trickle irrigation on the yield response of potato (Solanum tuberosum L. cv. Norgold Russet `M') was conducted at Lubbock, Texas. The objective was to evaluate the effects of trickle emitter placement on yield of #1, #2, marketable, cull, small, and total tubers. Trickle emitter lines were positioned 1) on the soil surface, 2) with the tuber pieces (4-inch depth), and 3) at S-inch depth. Irrigation was applied daily to replenish the water lost the previous day based on pan evaporation and crop coefficients. Marketable tuber yield was ≈ 8.9 to 11 tons/acre for all irrigation treatments. In both years, the proportion of misshapen potatoes (culls) was significantly greater for the S-inch depth irrigation treatment than for the surface or 4-inch depth treatments (2.9 vs. 0.71 and 0.67 tons/acre and 3.3 vs. 0.89 and 1.16 tons/acre, respectively). The misshapen tubers were directly influenced by trickle emitter placement and indirectly influenced by temperature differences within the tuber zone.

“…a) Produção e número de tubérculos -O decréscimo na produção de tubérculos com o aumento na tensão de umidade do solo, conforme revelam os resultados, tem sido amplamente reconhecido (ELLISON & JACOB, 1954;FULTON & MURWIN, 1955;BOX et al, 1963;FUEHRING et al, 1966). Assim, nos tratamentos onde a irrigação impediu que o solo atingisse níveis de água disponível inferiores a 60%, a produção foi sensivelmente superior aos tratamentos com níveis mais reduzidos de umidade.…”

RESUMONeste trabalho foi realizado um estudo para avaliar os efeitos da irrigação e fertilizantes no rendimento, número e tamanho dos tubércu¬ los de batata. A irrigação foi baseada na umidade média do solo quando atingia as tensões de 0,3; 0,6; 1,0; 3,0 e 10,0 bares. As doses de fertilizantes aplicadas foram de 40 kg/ha de N, 80 kg/ha de P 2 O 5 e 40 kg/ha de K 2 0, sendo a dose 1, 40-80-40 kg/ha de N, P 2 0 5 e K 2 0, respectivamente.Os melhores rendimentos foram alcançados a tensões de umidade do solo menor do que 1,0 bar e as doses 3, 4 e 5 de fertilizantes. Não houve diferença significativa no número de tubérculos entre os tratamentos.Foi observado com aumento na porcentagem de tubérculos maiores nos tratamentos com tensão de umidade de 0,3; 0,6 e 1,0 bar e doses 4 e 5 de fertilizantes. Por outro lado, foi obtida uma alta porcentagem de pequenos tubérculos a altas tensões de umidade (acima de 1,0 bar) e doses 1 e 2 de fertilizantes. INTRODUÇÃOO crescimento das plantas e a produção de tubérculos de batata são intensamente influenciados pelas condições de umidade e fertilidade do solo (ELLISON & JACOB, 1954;BOX et al., 1963). Os estudos para avaliação das variações dos níveis de umidade e fertilidade do solo tem sido conduzidos para condições específicas de solo, clima e variedade, proporcionando resultados.diferentes em relação ao tratamento correspondente aos maiores rendimentos. Assim, BLAKE et al. (1955) não encontraram diferenças significativas na produção de tubérculos, em plantas submetidas a teores mínimos de 67 ou 33% de água disponível no solo. Resultado semelhante foi encontrado por FULTON & MURWIN (1955) entre tratamentos com teores mínimos de 75 e 50% ide água disponível. No entanto, atingindo 25% a produção foi sensivelmenie reduzida. Por outro lado, FUEHRING et al. (1966) verificaram redução no rendimento e tamanho dos tubérculos quando apenas 21% da água disponível havia sido retirada do solo.
