Abstract

The research was aim at studying the effect of application of gypsum and manure to growth, biomass yield, dry matter yield, dry matter content and crude protein of Benggala grass. This study used factorial design with nine replications. The first factor was manure dosages i.e. 0 and 20 ton ha-1. The second factor was gypsum dosages i.e. 0, 0.75, 1.5 and 3 ton ha-1. Variables to observe were relative growth rate (RGR), biomass yield, dry matter yield, dry matter content and crude protein. The application of 20 ton manure and 3 ton gypsum per hectare resulted the highest values of  RGR, biomass yield, dry matter yield, dry matter content and crude protein; they were 0.86 g day-1, 1039.4 g pot-1, 219.1 g pot-1, 20.9% and 8.1%, respectively. Response of RGR, biomass yield, dry matter yield, dry matter content and crude protein to gypsum application with 20 ton manure  ha-1 were linier.  Keywords :  benggala grass,  saline soil, gypsum, manure, nitrogen.

Abstract

The purpose of this research was to evaluate the agronomic effectiveness of rock phosphate, biological fertilizers (Rhizobium and bio-phosphate) and their combinations on dry matter (DM) production, nutrient content and in vitro dry matter digestibility (IVDMD) of Stylosanthes guianensis CIAT 184. This research was conducted at Forage and Pasture Laboratory, Universitas Gadjah Mada, Yogyakarta, Indonesia from February – October 2010. A strip plot design which consisted of two fertilizer factors with three (3) replicates was used. The first factor was the horizontal factor and consisted of four levels of biological fertilizers (Rhizobium and bio-phosphate) namely: M0 = control, M1 = Rhizobium (0.5 g/plot), M2 = bio-phosphate (0.6 g/plot) and M3 = combinations of Rhizobium and bio-phosphate. The second factor was the vertical factor and consisted of three levels of rock phosphate, namely: P0 = control, P1 = 250 kg/ha (32.5 P kg/ha) and P2 = 500 kg/ha (65 P kg/ha). Defoliation was carried out every three months for 9 months. Results of the study showed that there was no significant difference in DM production (kg/ha) amongst treatments. Although the current research showed no significance difference amongs the treatments, DM production increased in the 2nd harvest (12.3%) and 4th harvest (7.1%) between P0 and P1. Combinations treatment P1M2 (21073.63 kg/ha) had the highest average DM production amongs treatments. Statistical analysis followed by Duncan’s new Multiple Range Test (DMRT), showed that rock phosphate can significantly (P<0.05) increase fiber production of Stylosanthes guianensis. It showed that treatment P1 increased crude fiber production by 12.2% from 5864, 47 kg/ha to 6580,19 kg/ha. In addition, tests further revealed that there was a difference between M1 and M2, but had no effect on M0. There was no significant effect on production (kg/ha) of crude protein, phosphorus, nitrogen free extract (NFE) and ash. In conclusion, treatments with rock phosphate and bio-fertilizers tend to increase productivity of Stylosanthes guianensis CIAT 184.(Key words: Stylosanthes guianensis CIAT 184, Rock phosphate, Bio-phosphate, Rhizobium, and In vitro dry matterdigestibility)

Abstract

This research is aimed to determine the effect of various concentrations (0, 1, 2, 3, 4 and 5 mg/l) of 2,4-D (dichloropenoxy acetic acid) on callus induction of Lamtoro (Leucaena leucocephala) and its somatic embryogenesis stimulated using different concentrations of 0, 0.5, 1.0, 1.5 and 2.0 mg/l of growth regulators, namely NAA (Naphthaleneacetic acid) and kinetin. Percentage of callus were measured and somatic embryogenesis from callus were subjected to description analysis. The results showed that callus percentage were varied from 29.34% (1 mg 2,4-D/l) at first week (white color and crumb) to 83.67% (4 mg 2,4-D/l) at fourth week (white yellowish color and compact), and embryo somatic varied from 19.33±2.52 (2 mg NAA and 0 mg kinetin/l) to 81.33±11.50 (1.5 mg NAA dan 2.0 mg kinetin/l). It can be concluded that optimum callus induction (83.67%) was recorded when concentration of 2,4-D was given at the rate of 4 mg/l. The largest number of embryos in concentration of 1.5 mg/l NAA and 2.0 mg/l kinetin, and embryo somatic 81.33±11.50.

Abstract

The aim of this study were to obtain the optimum level of NPK fertilizers of sudan grass and economic of NPK fertilizers utilization. The randomized completely block design (RCBD) were used to evaluate, namely 4 levels of fertilizer doses NPK and 4 blocks for determine the grass production. The treatments for randomly N application, namely: No (PO); N150 (P1); N300 (P2); and N450(P3). Phosphorus and K fertilizer were given at the same rate, that were 300 kg P2O5 and 150 kg K2O ha-1. The results of study showed that DM production for PO (3.19 tonha-1) differed significantly with P1, P2 and P3; but between P2 and P3 did not differ significantly. There were increased DM production due to increasing of fertilizers applied. The values of DM production increasing percentage for P1, P2, and P3 compared with PO, for DM were 69.44%, 80.45% and 85.28%, respectively. The increased percentages of DM production of P3 tended to decrease. Therefore, it can be summarized that P2 (300 kg N, 300 kg P and 150 kg K ha-1) was optimum level for DM production. Based on partial budget analysis, indicated that cultivation of sudan grass with NPK fertilizer treatments yielded profit positively. The profit value for P1, P2, and treatment of P3 were Rp 581.500,-; Rp 2.009.500,-; and Rp 2.997.500,-per hectare, respectively.
