The effectiveness of giving organic matter to the productivity of tomato plants

Abstract

The assessment of the productivity of a land is not only based on natural fertility, but also the response of the soil and plants to the application of applied land management technology. Basic fertilizer is given at the time of planting by sprinkling it around the plant. The organic fertilizer used in this study is organic fertilizer from cow dung that has been completely decomposed. The dose of organic fertilizer and NPK according to the treatment is A=Control, B=NPK 180 Kg/ha, C=100% NPK, D=Organic Manure 4 tons/ha+NPK 100%, E=Organic Manure 4 tons /ha+NPK 75%, F=Organic Manure 6 tons/ha+NPK 100%, G=Organic Manure 6 tons/ha+NPK 75%, H=Organic Manure 8 tons/ha+NPK 100%, I=Organic Manure 8 tons/ha+75% NPK. With treatment (i) with the type of organic fertilizer and the dose of NPK gave the highest value in the vegetative and generative phases, for the generative phase (growth) plant height (93 cm), number of leaves (73 strands), stem diameter (0.88 cm), flowering age (26 days after planting), number of flowers per plant (66). While in the generative phase (production) the number of fruits per plant (55 pieces), fruit diameter (4.4 cm), fruit weight per fruit (82.4 grams) and fruit weight per treatment was 631.3 kg and fruit weight per hectare reached 28471 Kg. Organic Manure 8 tons/ha (288.3 grams/plant)+75% NPK (40.1 grams/plant) (I) of 58.1 tons/ha, is a very appropriate dose for nutrient absorption to produce fruit high production. The use of a combination of organic and inorganic fertilizers can increase the amount of organic matter in the soil and can provide the best nutrients for tomato plant growth so that it affects production.
