Glutamic Acid Application for Enhancement of Growth and Productivity of Okra Plant (Abelmoschus esculentus L. Moench)

Abstract

Red okra fruit has high nutritional value and fiber but still has low production. Monosodium glutamate (MSG) consists of sodium and glutamic acid. In plants, sodium can role of replacing potassium, stomata physiology, and chlorophyll biosynthesis. Glutamate as the nitrogen donor in primer metabolism and gibberellic acid precursor. The assumption that MSG in plants has a positive impact. This research aimed to examine the effect of MSG and the optimum dosage for enhances of growth and production. This research was conducted with Completely Randomized Designs (CRD) with one factor, is the MSG dosage (0, 3, 6, and 9 g). Quantitative data were analyzed using analysis of variant (ANOVA) dan Duncan’s Multiple Range Test (DMRT) at a 95% confidence level. The result shows that the MSG treatment enhances the growth of the okra based on parameters of plant’s height, fresh weight of plant, dry weight of plant and the width of the leaf and enhances the production of the okra based on the flowering time, the number of the flower, the number of the fruit, the percentage of flower becoming fruit, the weight of fruit, width of fruit, and the diameter of the fruit. The optimal dosage of MSG for okra production and growth is 3 g/plant.

Investigation of Foliar L-Glutamic Application on the Resistance to the Capacity of the SC2121 Tomato Variety (Solanum lycopersicum L.) to Long-Term Salinity Stress

“…The number of leaves peaked at 100NaCl, 500GLU, and 50NaCl-50GLU. The number of branches and the fruit characteristics found in the present study were similar to those reported by Kavasoğlu and Ceyhan, (2018) for beans, Civelek and Yıldırım (2019) for tomatoes, and Septiyana et al (2019) for okra. In another study, Omer et al (2013) examining the chamomile plants grown under salty conditions reported that the plant height, the number of branches, and the number of flowers decreased under salty conditions but branch number and flower yield increased in response to the amino acid treatments.…”

“…The decrease in the number of flowers was also reported by Nahed et al (2007). Geshnizjanı and Khosh-Khui (2016) and Septiyana et al (2019), differing from the present study, stated that amino acid treatment increased the number of flowers. However, Jannesari et al (2016) emphasized that it stimulated the fruit yield under salty conditions but amino acid treatments had no significant effect.…”

“…Moreover, since they inhibit the synthesis of reactive radicals or stimulate the antioxidative defense systems, they play an important role in protecting plant cell structures against salinity stress effects (Noroozlo et al, 2019). Glutamate, as the main NH4 + donor, is metabolized to other amino acids such as proline, glycine, and arginine, and also plays an important role in chlorophyll biosynthesis, activation of plant hormones, cell division, and phytochelatin activities (Septiyana et al, 2019).…”
