Organic and Inorganic Fertilizers Application on NPK Uptake and Production of Sweet Corn in Inceptisol Soil of Lowland Swamp Area

Abstract

Abstract. This study objective was to determine the dose of organic and inorganic fertilizers which can increase N, P and K nutrients uptake as well as the growth and yield of sweet corn on inceptisol soil of lowland swamp. Inceptisol soil has low soil fertility and relatively low to moderate levels of organic matter content. Application of organic fertilizer on inceptisol soil of lowland swampis expected capable to increase N, P and K nutrients as well as yield of sweet corn. This research was conducted from April to July 2014 at Experimental Farm Area of Pulau Semambu Village, Indralaya Utara Subdistrict, Ogan Ilir District, South Sumatra Province. The method used in this research was randomized block design consisting treatments as follows: 75% inorganic fertilizer + 5 ton.ha -1 organic fertilizer, 50% inorganic fertilizer + 5 ton.ha -1 organic fertilizer, 25% inorganic fertilizer + 5 ton.ha -1 organic fertilizer, 0% inorganic fertilizer + 5 ton.ha -1 organic fertilizer with six replications. The recommended dose of inorganic fertilizerswas 200 kg.ha -1 urea, 100 kg.ha -1 SP-36 and 100 kg. ha -1 KCl. The results showed that treatment of 75% of inorganic fertilizer + 5 ton.ha -1 organic fertilizer had produced N, P and K nutrients uptake with magnitude of 1.850, 0.418 and 2.374 g.plant -1 respectively as well as good growth and yield of sweet corn with magnitude of 356.36 g. plant -1 or 15.21 ton ha -1 .

Comparative Effects of Soil and Foliar Applications of Tithonia-Enriched Liquid Organic Fertilizer on Yields of Sweet Corn in Closed Agriculture Production System

“…The magnitude of nutrient uptakes and contents in sweet corn was presumably sufficient enough to support growth and development. Research conducted by Marlina et al (2017) reported that fertilizing sweet corn with 5 t/ha organic fertilizer brought about nitrogen, phosphorus and potassium uptakes as much as 16.28 mg/plant, 3 mg/plant and 12.08 mg/plant, and produced weight husked ears of 333.68 g/ plant. This number was higher than results from this experiment with average of husked ears ranged from 220.43 to 270.63 g/plant, which was still within the range of its variety description.…”

Impact of T. harzianum and G. mosseae Inoculum and Phosphate Rocks on the NPK Content in Barley Crop (Hordium Valgari L.)

“…On the other hand, the application of T. harzianum fungus significantly increased the average plant content of phosphorous by 0.358% compared to the control treatment of 0.310%. The reason is attributed to the role of the T. harzianum in dissolving phosphorous and transforming it from the form that is not available for absorption by the plant to the form available for absorption and its role in forming a dense root system that results in the efficient absorption of nutrients [21].…”

Effect of Trichoderma Harzianum and Algae Chara sp and Levels of Mineral Fertilizer on Plant NPK Concentration and Wheat Yield Triticum aestivum L.

“…Trichoderma harzianum has been shown in multiple studies to aid plant growth by making more of the essential elements nitrogen, phosphorus, and potassium available to the plant. As a result of efficient nutrient uptake, the fungus is able to breakdown phosphorous and convert it to an absorbable form, all while generating a dense radical group [8]. Laws that provide for the collection of algae and identify their types and places of gathering in order to support plant species, as the specialized centers in composting have worked to find various ways to deal with the increasing quantities of algae and its organic waste, which is used as fertilizer in the agricultural field, where it is used, after drying it and then grinding it completely.…”
