Vegetative Growth Response of Celery to Organic Fertilizer

This study analyzes the effects of liquid organic fertilizer on the vegetative growth of celery plants. It examines variables such as plant height, leaves number, and plant weight, aiming to determine the appropriate dosage of organic fertilizer for celery cultivation.

  1. Vegetative Growth Response of Celery (Apium graveolens L.) to the Application of Organic Fertilizer A Rut Normasari Faculty of Agriculture Universitas Klabat Manado, Indonesia 5th International Scholars Conference October 30-31, 2017 Asia-Pacific International University Thailand

  2. INTRODUCTION • Celery (Apium graveolens L.) is one of the most widely used vegetable commodities for flavoring, supplementing, decorating dishes, and is used in many different types of foods.

  3. INTRODUCTION • Celery demand from year to year continues to increase both domestic and foreign demand. • Intensive cultivation is needed to produce high quality of celery crops. • Appropriate fertilizer and fertilization process is very important for celery plants to produce fresh celery production.

  4. INTRODUCTION • Liquid organic fertilizer is a fertilizer derived from the remnants of plants and animals that have been processed and given through the leaves by spraying or watering on the crown of plants to be absorbed, in order to meet the needs for growth and development of plants.

  5. INTRODUCTION • The advantage of liquid organic fertilizer is that the nutrients given will be more quickly absorbed by the plant than by giving through roots or soil (Kusmarwiyah & Erni, 2011). • Liquid organic fertilizers in addition to improving the physical, chemical, and biological properties of the soil, can also help increase crop production, improve the quality of plant products, reduce the use of inorganic fertilizers and as an alternative to manure (Ji, Dong, Shi, & Min, 2017).

  6. AIM • The objective of this research was to get the right doze of liquid organic fertilizer A that is suitable for use in cultivation of celery plants.

  7. METHODOLOGY • K0 (without treatment of organic fertilizer A as control) • K1 (2 ml of organic fertilizer A / liter of water) • K2 (4 ml of organic fertilizer A / liter of water) • K3 (6 ml of organic fertilizer A / liter of water) • K4 (8 ml of organic fertilizer A / liter of water) *4 replications

  8. METHODOLOGY • The variables observed from this research were plant height, leaves number, and plant weight of celery. • The data obtained in the study were analyzed by using variance analysis and continued by Duncan’s multiple range test.

  9. RESULTS The Average Height of the Celery Plant at Some Level of Treatments *weeks after planting

  10. RESULTS The Average Leaves Number of the Celery Plant at Some Level of Treatments *weeks after planting

  11. RESULTS The Average Plant Weight of the Celery Plant at Some Level of Treatments

  12. DISCUSSION • The application of organic fertilizer A on celery does not give a significant effect on vegetative growth of celery plant that is on variable of plant height and leaves number, but gives significant effect on plant weight. • The results supported the study of Duaja, Nelyati, & Tindaon (2012) showed that the application of organic fertilizer in celery did not show any significant difference in celery result.

  13. DISCUSSION • It is assumed that nutrients have been met from planting media. Suspected crop response to all the treatment is the same. This may be due to plant genetic factors that exhibit similar properties (Gao et al., 2014).

  14. DISCUSSION • Organic fertilizer A gave effect to the mass of plant; it was seen from the variables of weight plant that give a significant different effect. • If organic fertilizers are provided with the right concentration it will work well, and if excessive concentration or deficiency will inhibit plant growth (Uluputty, 2015).

  15. DISCUSSION • In this study, organic fertilizer used was liquid organic fertilizer. Organic fertilizers are effective in maintaining environmental sustainability and plant growth on long-term use. In addition, watering and fertilizing patterns can improve the efficiency of nutrient use and reduce the risk of nutrient loss (Ceretta et al., 2010).

  16. CONCLUSION • The treatment of organic fertilizer A did not give effect to plant vegetative growth that is on variable of plant height and number of leaf, but gave significant different effect to plant weight. • Overall, the best treatment for vegetative growth of celery plants is K1 treatment.
