PERCIVAL B. ALIPIT. March, 1980. University of the Philippines at Los Banos. Performance of White Potato (Solanum tuberosum Le) Under Varying Soil Moisture Regimes and Nitrogen-Potassium Levels. Major Professors Dafrosa A, del Rosario.<br/><br/>A study was conducted for two cropping seasons to determine the influence of soil moisture and nitrogen--potassium fertilizer on yield and quality and other horticultural characteristics of white potato *Cosima’ in<br/>ta Trinidad, Benructe<br/><br/>Irrigation during the carly dry season from mid-November to early February after 25 to 75% of the available soil moisture had been depleted did not influence total yield, tuber sines, and composition the late dry season from March to May, higher total yield and larger sized tubers were obtained With irrigation at 25% available soil moisture depletion.<br/><br/>High yields from more frequently irrigated plants could be due to the high net assimilation rate, water-use efficiency, and relative water content observed. In both<br/>cropping seasons, however, the weight of marketable tubers produced by plants irrigated at 25 and 50% available soil moisture depletion was comparable. Moisture stress (75% depletion of the available soil moisture prior to irrigation) resulted in a high incidence of growth cracks and lobby Second growth in both seasons. Hollow heart observed only in the carly dry season was not affected by the soil moisture treatments.<br/><br/>Potato plants grown in a soil containing 0.14% N, 10.40 ppm NO.=N and 0.23 me K and fertilized with 60-240 kg N-K/ha produced comparatively high total and marketable yield as & consequence of high leaf area index and relative water content. Fertilization with 120--300n kg N-~K/ha increased the marketable yield especially of the larger sized tubers. High N and low K levels (180-180 kg N+K/na) inercascad NO.=N uptake resulting in more tubers with second growth and hollow heart, High N and K (180-300 kz N~K/ha) promoted havulm growth and<br/>produced tubers with low dry matter and high sugar content.<br/><br/>Application of 60-0 kz N~K/ha to plants in a soil With 0.14% N, 7236 ppm NO.-N and 0.65 mc K resulted in Comparatively good haulm development, high marketable<br/>yield of larger sized tubers, and high tuber specific gravity. Increasing the rate to 120“120 ke N-K/ia resulted in high crop growth and nct assimilation rates and relative water content accounting for the highest total a and marketable yield obtained. <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/> |
