Abstract

Non-organic agriculture has succeeded in increasing the production of lowland rice, but on the other hand also has a negative impact on the ecosystem of agriculture and the environment, such as the decreasing content of soil organic matter. One effort that can be done, is by adding bio-slurry organic fertilizer to the NPK fertilizer. This study was conducted to determine the effect of the combination of bio-slurry fertilizer and NPK fertilizer on the production of four rice paddy varieties. This research by experiment was conducted in Screen House Agrotechnopark, Faculty of Animal Husbandry and Agriculture, Diponegoro University, Tembalang Semarang campus, taking place from October 2018 to January 2019. The experiment used a randomized completely block design with two factors and three replications. The first factor was a combination of bio-slurry + NPK fertilizer ie without N (P0) fertilizer, NPK 550 kg ha-1 fertilizer (P1), bio-slurry fertilizer 3 tons ha-1 + NPK fertilizer 400 kg ha-1 , 6 tons ha-1 bio-slurry fertilizer + 250 kg ha-1 NPK fertilizer, 9 tons ha-1 bio-slurry fertilizer + 100 kg ha-1 NPK fertilizer and 12 tons bio-slurry fertilizer ha-1. Whereas the second factor was the lowland rice varieties namely Inpari 23, Sultan Unsrat, Sintanur and Gilirang. The results of the variance analysis showed that the combination of bio-slurry + NPK fertilizer and lowland rice varieties had a very significant effect on grain yield per clump, number of filled grains, number of empty grains, total grain count, weight of 1000 grains, rice yield per pot and harvest index. The highest grain yield per clump (85.33 g) was obtained from the treatment of 550 kg ha-1 NPK fertilizer, while the highest grain yield per clump (58.06 g) was obtained from the Gilirang variety (V4), the highest total grain amount (174.58 grains) was obtained from the treatment of NPK 550 kg ha-1 and (212.28 grains) fertilizer produced by varieties Inpari 23. The highest yield per pot of rice (61.83 g) was obtained from the treatment of 550 kg ha-1 NPK fertilizer , while the highest paddy rice varieties which produced rice per pot of (63.22 g) were Inpari 23.

Abstract

Vesicular-arbuscular mycorrhizae (VAM) inoculation of forage crops in combination with P. fertilization are important to improve forage crops production and nutritive value in the nonproductive soils. A greenhouse experiment was carried out to study the effect of YAM (Glomusfasciculatum, Entrophosphoracolumbiana, and Gfasciculatum+E. columbiana) in combination with P fertilization (superphosphate-36 and rock phosphate) on the dry matter production, N and Zn uptake of Pueraria phaseoloides (puero), Factorial 2x4 in completely randomized design was used in 5 replicates. The results showed that dry matier production, N and Zn uptake of puero with YAM inoculation were significantly higher compared to without YAM inoculation. Dry matter production, N and Zn uptake of puero with superphosphate-36 were signifcantly higher compared to rock phosphate fertilization.

Abstract

Rock phosphate (RP) fertilizer belongs to slow available source of phosphorus compared to superphosphate (SP), and mycorrhiza inoculation maybe a promising technique to overcome the problem. The symbiosis between mycorrhiza and Zea mays saccharaiaSturt in unsterilized soil has been less studied compared to sterilized soil. A greenhouse experiment was con• ducted on acid latosolic soiland low phosphorus availability. The experimental design was a factorial 2x2x3 in 3 replicates. The treatments were soil sterilization (unsterilized, sterilized), mycorrhiza inoculation (uninoculated, inoculated) and P fertilization (RP-10, RP-20, SP-36). All pots received fertilization of 200 kg N/ha (6 g urea/pot), 150 kg K20/ha (3.50 g KCl/pot) and 150 kg P20/ha of three kinds of P fertilizer source were RP-10 (21 g/pot), RP- 20 (10.50 g/pot) and SP-36 (6 g/pot). The latosolic soil was sterilized by autoclaf at 121°c for 15 minutes. Each pot contain 8 kg dry soil and inoculated by 40 g soil inoculum of Glomus manihotis according to the assigned treatment at the time of planting. Each pot contain 2 plants of Zea mays saccharata Sturt. Zea mays was cut at ground level at 6 wekks after planting and analyzed for dry matter (DM), N and P content. Dry matter production, N and P uptake with SP fertilizer were significantly higher compared to RP (RP-IO, RP-20) on both srreilized soil and unsterilized soil. Dry matter production, N and P uptake with SP fertilizer on sterilized soil were significantly higher compared to unsterilized soil, while RP fertilizers (RP-10, RP-20) were not significantly different. The DM production, N and P uptake of Zea mays were not significantly affected by the interaction.between the treatments of mycorrhiza inoculation, P fertilization and soil sterilization.

Abstract

Thisstudy aims to assess the effect of a combination between organic and phosphate fertilizer on dry matter production, nitrogen and phosphorus levels of sweet sorghum forage. The design was a single factor randomized complete block design with eight treatments and three replications. Parameters weredry matter production, nitrogenand phosphorus levels. The results showed that the manure 'plus'and charcoal application at first defoliation did not significantly affect the dry matter but at the second defoliation the treatments significantly affected the dry matter production. Manure 'plus' and charcoal application showed significant effects on levels of nitrogen and phosphorus at the first and the second defoliations, so that the combination treatmentgave better results than a single fertilizer (manure fertilizer, TSP, BP and Charcoal).
