Abstract

Zeolite generally have a very high exchange ion capacity and capability to catch ions. Therefore, zeolite is used on agriculture to reduce ion movement around the root zone and to increase the use of fertilizer by plant. A research have been established on 1999/2000 using zeolite from two sites that represent two type of soil, Planosol soil from Jakenan (Pati) and Podsolic soil from Tamanbogo (Lampung).Group randomize design with three repetition is used on this research. Fertilizer treatment on this research are 60-100 % P or K and 0-40% zeolite, 100% P or K + 200- 300% kg/ha zeolite. The final result of this research showed that in order to produce high quality of paddy on podsolic soil need the P fertilizer. The zeolite been given along with P fertilizer worth while to increases efficiency, even though it did not positively increasing yield. Adding 300 kg/ha zeolite can reduce the use of fertilizer around 20% P. The Same thing happened to fertilizer K on planosol. Zeolite plus which enriched by a number of minerals giving a better result compare to the one without enrichment. On greenhouse atmosphere, though dosage of zeolite plus (5-10 t/ha) used to increase exchange ion capacity on soil, producing rice around 11.9 t/ha. But on the field, the production decreases cause by heavier disease attack due to the too crowded plantation and too damp condition around the canopy. This is why it is necessary to give the right zeolite plus dosage, not just to increases efficiency, but also to make it financially reachable by the farmer.

Abstract

The continuous use of inorganic fertilizers without the application of organic fertilizers can cause nutrient imbalances in the soil, low fertilization efficiency, damage to soil structure, and low soil microbiology. This experiment was conducted in Experimental Station of Indonesia Center for Rice Research Sukamandi Jaya Village, Subang District, West Java from July to November 2020. The objective of the experiment was to find out of N, P, K and organic fertilizer that gave the best yield on growth and yield of rice (Oryza sativa L.). The research was used experimenthal method it was arranged in split plot design with 6 threatment and 4 replications. As the main plot was N, P, K fertilizer, consist of 4 threatment of fertilizer: P1 (kontrol), P2 (+PK), P3 (PHSL), P4 (NP), P5 (+NK), and P6 (+NPK). As subplot was organic fertilizer: B1 (2 ton/ha), B2 (compost rice straw 5 ton/ha), and B3 (control). The effect of treatment is analyzed with variety analysis and if the F test is 5% significant, then to find out the best treatment continued with further DMRT tests (Duncan Multiple Range Test). The results showed that there was an interaction between the provision of inorganic and organic fertilizers to the height of plants aged 35 days after planting and 1000 grains weight. Meanwhile, at the height parameters of plants aged 21 days after planting, 57 days after planting, 64 days after planting, and 84 days after planting, number of tillers, number of panicles per hill, number of grains, and the grain yield there are real influences independently. The highest grain yield of 4,84 Kg/tile (6,45 tons/ha) was achieved by P5 (+NK) treatment and was not real different from P3 (PHSL), P4 (+NP), and P6 (+NPK) treatment with consecutive weights of 4,82 Kg/tile (6,43 tons/ha), 4,44 Kg/tile (5,92 tons/ha), and 4,46 Kg/tile (5,95 tons/ha).
