Abstract

Manure enriched by rock phosphate (RP) and inoculated with biodecomposer very important to improve the upland fertility. Residual effects of applied manure can be used for the next growing season. The objective of the research was to investigate the residual effects of some kind of manure on sweet corn (Zea mays saccharata), dry matter (DM) and P production of stover on second growing season. A field experiment of completely randomized design with 7 treatments and four replicates. Level of P (RP), N (urea) and K (KCl) fertilizers was 66 kg P/ha, 200 kg N/ha, and 125 kg K/ha, respectively. All of manure application at 30 ton/ha and enriched with RP. The treatments at the first growing season were T0 (manure), T1 (manure +EM4), T2 (manure+starTmik), T3 (manure +stardec), T4 (manure granular+EM4), T5 (manure granular+starTmik), and T6 (manure granular+stardec). The sweet corn was harvested at 70 days, the stover was cut and measured for DM and P production. The result showed that effect of some kind of manure was not significantly different to sweet corn and DM production. Manure inoculated with biodecomposer resulted in signficantly higher of P production than without biodecomposer. Conclusion, all of manure resulted in similar on sweet corn and DM, except manure inoculated with biodecomposer resulted in higher of P production than without biodecomposer.

Abstract

The characteristics of crop-livestock systems is crop yield for food or vegetable, and stover or leaf for ruminant feed, being the manure used as organic fertilizer. Phosphorus (P) is the major plant nutrient and considered one of the primary factors limiting crop yields. Rock phosphate (RP) is one of some organic P fertilizer which could increased its solubility if mixed at the initial phase of manure decomposition process. The objective of the research was to investigate the influence of some kind of organic fertilizer on production and nutrient concentration of okra (Abelmoschus esculentus L) leaf as forage. A field experiment of randomized block design with 9 treatments and three replicates was done, and the treatments were T1 (RP), T2 (azolla compost), T3 (cow manure), T4 (goat manure), T5 (poultry manure), T6 (azolla+RP), T7 (cow manure+RP), T8 (goat manure+RP), T9 (poultry manure+RP). Okra leaf defoliated at 80 days after planting, and continued measured for fresh leaf production, nitrogen and phosphorus concentration. The results showed that the treatment significantly affected to the fresh leaf production, concentration of nitrogen and phosphorus. The result of DMRT showed that fresh leaf production, concentration of N and P significantly higher if fertilized by goat manure+RP (T8) and poultry manure+RP (T9) compared to another treatments.

Abstract

Alfalfa (Medicago    sativa    L.) as one of legume forage crops for ruminant livestock is very sensitive to the phosphorus deficiency. Phosphorus fertilizers have been used widely to overcome those problem. However, the high cost of superphosphate (SP) is now focusing attention on cheaper rock phosphate (RP) fertilizer. A field experiment was conducted on a latosolic soil (low pH, and low available Bray II extractable P). The objective of the research is to evaluate the effect of phosphorus fertilizer from difference sources on dry matter production, and in    vitro dry matter digestibility of alfalfa. Completely randomized block design with 7 treatments in 3 replicates was used in this field experiment. The treatments were T0 (control), T1 (SP, 100 kg P2O5/ha), T2 (SP, 200 kg P2O5/ha), T3 (SP, 300 kg P2O5/ha), T4 (RP, 100 kg P2O5/ha), T5 (RP, 200 kg P2O5/ha), T6 (RP, 300 kg P2O5/ha). Size of each plot was 2 m x 2 m, and fertilized with P fertilizer (SP, RP) according to the assigned treatment. All plot received basal fertilizer of urea (50 kg N/ha), KCl (100 kg K2O/ha) and poultry manure (2 ton/ha). Medicago    sativa was defoliated on 12 weeks after planting and analyzed for dry matter (DM) production and in    vitro DM digestibility. Result showed that DM production significantly influenced by the treatments. Superphosphate fertilization resulted DM production significantly higher compared to control and RP, except on RP 300 kg P2O5/ha was non-significant difference. In    vitro dry matter digestibility (IVDMD) of alfalfa was not affected by the treatment. There was non-significant difference in IVDMD between the treatments. Therefore, RP (300 kg P2O5/ha) could replace SP to increased DM production and not affected for IVDMD of Medicago    sativa in acid latosolic soil.
