DIMERO, FE NOVERO. Inorganic Fertilizer Reduction with Wood Vinegar Supplementation in Cucumber (Cucumis sativus) ‘Puccini’ Variety. Dissertation. Doctor of Philosophy in Agriculture. Cavite State University, Indang, Cavite. April 2013. Adviser: Dr. Arnulfo C. Pascual.
A study was conducted to determine how much inorganic fertilizer can be supplemented with wood vinegar in pickling cucumber production. Decreasing application rate of inorganic fertilizer: T1-100 percent, T2-75 percent, T3-50 percent, T4- 25 percent of the recommended dose of inorganic fertilizer (RDIF), and T5- no inorganic fertilizer were used with constant application rate of wood vinegar, 1:200 dilution by drenching and foliar application were utilized. Growth and yield responses of experimental plants with the combined inorganic fertilizer-wood vinegar application were evaluated in terms of plant height, number of leaves, number of nodes, number of flowers, number of fruits developed, yield components, plant resistance against pest and postharvest characters of fruits. Cost and return in using decreasing levels of inorganic fertilizer with wood vinegar supplementation was analyzed.
No significant effects on plant height increase, number of leaves, number of nodes, flower initiation, fruit development, number of flowers and fruits attached to the plant were observed with inorganic fertilizer- wood vinegar treatments at specific period of growth and development. Results imply that decreasing application of inorganic fertilizer elicited the same growth and development effects on cucumber plants as when it is applied in combination with wood vinegar. Symptoms of toxicity effects were observed in plants given the recommended dose of inorganic fertilizer with wood vinegar. Flowering and fruit initiation were, likewise, not affected by the decreasing application rate of inorganic fertilizer. Percent pest infestation in cucumber plants were generally the same in all experimental plants.
Application of wood vinegar to Puccini pickling cucumber with only 25 percent of the recommended dose of inorganic fertilizer gave significantly higher yield than all other treatments. Application of wood vinegar alone gave fruit yield comparable to application of wood vinegar with inorganic fertilizer higher than 25 percent of the recommended dose. Fruit characters such as length to diameter ratio, shape and moisture loss on storage at ambient temperature were not affected by treatments.
General acceptability of fresh and pickled cucumber as determined by sensory evaluation did not also differ with treatments.
Application of T4 using 25% of the recommended dose of inorganic fertilizer supplemented with wood vinegar is considered the most productive treatment and gave the highest net income based on the cost and return analysis in the production of Puccini pickling cucumber on a per hectare basis.
