PERFORMANCE OF RADISH (Raphanus sativus L.) AS AFFECTED BY DIFFERENT LEVELS OF FISH AMINO ACID

This study was conducted under MSU Campus, Fatima, General Santos City from October to November 2021 to determine the appropriate amount of fermented fish amino acid that was sufficed as a supplementary fertilizer and to evaluate the performance of radish as affected by different levels of fermented fish amino acid. The study was conducted following a Randomized Complete Block Design (RCBD) with four treatments, and was replicated three times. Treatments were designated as follows as follows: T1- control (No application); T2: 5% FAA + recommended rate of 1⁄2 NPK for radish, T3: 10% FAA + recommended rate of 2 NPK for radish and T4: 15% FAA + recommended rate of 2 NPK for radish. Treatments were compared in terms of plant height, number of leaves, root length, root weight, root diameter, number of marketable and non-marketable roots, and projected yield per hectare. Results disclosed that fish amino acid, regardless of the level tested, did not influence the growth of radish especially in terms of plant height, number of leaves, root length, root weight, root diameter, and even in terms of projected yield per hectare.Results nevertheless showed that fish amino acid, particularly at 10% level, showed significant effect on the number of marketable and non-marketable roots. Specifically, there were substantially fewer non-marketable roots and significantly greater number of marketable roots. In summary, FAA did not have any effect on the yield and growth parameters parameters of radish, but has substantial effect in increasing marketable roots and vice-versa. In finale It is suggested that similar study be conducted on radish following different fermentation periods and different frequencies of application, with emphasis on the nutrient composition of FAA. This way, FAA applications may be optimized and its' effects on radish are further analyzed.
