Abstract

The aim of this study was to evaluate performance and in vitro digestibility of Guinea grass grown on saline soil. Yield, quality, and in vitro digestibility of Guinea grass cultivated on coastal area with crop populations of 10,000,20,000, and 30,000 plants per hectare. Experiment was conducted following randomized complete block design (RCBD). Higher crop population increased fresh and DM biomass production, crude protein (CP) yield, dry matter(DM) content, neutral detergent fiber (NDF), lignin, and hemicellulose content, but decreased CP content, and in vitro organic matter digestibility (OMD). The increased population had no effect on acid detergent fiber (ADF) and in vitrodry matter digestibility (DMD). It could be concluded that guinea grass was recommended to be planted in saline coastal area by addition of fertilizer 20 tons/ha manure, 3 tons/ha gypsum, and 50 kg N (239 kg ZA/ha) as source ofnitrogen.(Keywords: Forage, Salinity, Saline soil, Manure, Gypsum, Nitrogen source)

Abstract

Andisols has relatively low phosphorus availability due to its adsorption by allophane. Phosphate solubilizing bacteria (PSB) increases the availability of P via release of adsorpted-P. The aims of this research were to determine: 1) anorganicP solubilization, 2) organic-P mineralization, 3) blocking of Andisols adsorption site, and 4) effective PSB inoculant. The research was arranged in completely randomized design, with PSB inoculant as treatment. Variables observed were solubleP, mineralize-P, adsorpted-P, pH, total acidity, PSB population, phosphatase and phythase activity, relative surface charge, and maize’s growth component. The result showed that PSB inoculation increased soluble-P from 30 to between 150 and 195 ppm P, increased mineralize-P from 23.7 to between 63.6 and 91.7 ppm P, and decreased P-adsorption from 95 to between 36 and 13%. PSB inoculation decreased the Andisols pH, increased the total acidity, PSB population, the phosphatase and phytase activity, and PSB had relatively high of relative surface charge (69%). The PSB inoculation increased maize P absorption in the range of 70 and 75 mg P plant-1, and increased relative agronomic effectiveness (RAE )between 145 and 150%. Liquid and solid PSB inoculant had no different effect in increasing maize growth. Keywords: Andisol, P release, phosphate solubilizing bacteria, phosphatase, phytase

Abstract

The natural zeolite was treated with alkali (NaOH) solution and heating at 100 oC for 12 and 24 hours. The natural zeolite was collected from Gunungkidul, Jogjakarta, Indonesia. The series of NaOH solutions was 0.5, 1.0, 1.5, 2.5, 3.5 and 4.5 M. The final product of the reaction (precipitate) was designated as ‘activated natural zeolite (ANZ)’. The cation exchange capacity (CEC) of the ANZ increased with increasing NaOH concentration up to 1.5-3.5 M. Treatment with NaOH 3.5 M and 12 hours in period of hydrothermal reaction resulted in a maximum CEC (395.6 cmol.kg-1). The maximum CEC also observed for treatment with NaOH 1,5 M, but consumed a longer time (24 hours). The increase in the CEC of the ANZ about 300 % higher than the original one. The XRD (X-ray Diffraction) peaks of the ANZ appear at 2.7, 3.2, 4.1, 5.1, 7.2 Å, this indicated a new crystalline matters (possibility phillipsite) present. Electron micrograph showed that the ANZ has a large cubic/prismatic structure with a perfect form.

Abstract

Farmyard manure and azolla are potential sources of organic fertilizer in organic paddy field. This study aimed to determine the effect of using farmyard manure and azolla on growth and yield of rice crop. The research method was field trial in an organic paddy field, Sukorejo Village, Sragen, Indonesia. Experimental design which used was a completely randomized block design with 9 kinds of treatment which are repeated in 3 blocks. These kind of treatments were the using of farmyard manure, azolla fertilizer, azolla inoculum, and the combinations which is based on the fulfillment of nutrient requirements of 120 kg N ha-1. Farmyard manure significantly increased the fresh weight of biomass (two-way ANOVA F = 3.13 p < 0.05), the weight of grains per panicle (two-way ANOVA F = 3.36 p < 0.05) and dry grain harvest (two-way ANOVA F = 3.71 p < 0.05). Azolla fertilizer significantly increased the plant height (two-way ANOVA F = 2.93 p < 0.05). Meanwhile azolla inoculum did not give significant effect on all parameters (both growth and yield). Dry grain harvest has very significant correlation with plant height (0.68**); fresh weight of biomass (0.79**); weight of grains per panicle (0.61**); and grain weight of 1,000 seeds (0.48*). The result of F test and correlation analysis showed that farmyard manure significantly increases the dry grain harvest through its role on increasing the weight of fresh biomass and grain weight per panicle. Azolla fertilizer also significantly increased the dry grain harvest through its role on increasing the plant height. However, the effect of Azolla fertilizer to increase the dry grain harvest was weaker than farmyard manure.

Abstract

Most of sugarcane are cultivated on Ultisols with low inherent soil fertility in Central Lampung. This experiment aimed to observe the effect of lime (CaCO3) and gypsum (Ca2SO4) on Fe, Zn, Mn, and Cu uptake of sugarcane. The experiment was conducted in Experimental Research Field of Gula Putih Mataram Enterprise, Central Lampung District. The experiment was designed using a split-plot, which consisted of lime application as the main plot and gypsum application as the sub plotwith three replications. The results showed that there were no significant influence of lime and gypsum application on micronutrient content of the soil. However, application of 2 and 3 tons of lime/ha could reduce soil Fe content about 349.86 and 328.07 ppm respectively within 0-20 cm soil in depthand it was significantly lower than comparing to Fe content (around 457.68 ppm) in control. Similarly, the effect of gypsum application at 0.25 ton.ha-1 decreased Fe content (355.42 ppm), while Fe content of non-gypsum application soil showed around 410.34 ppm. The analysis of other micronutrients did not indicate asignificant effect of lime or gypsum application.

Abstract

The study aims to determine fertility status of the soil after organic paddy experiments using kinds and doses of organic fertilizers. Experiment was conducted at greenhouse laboratory in Faculty of Agriculture Sebelas Maret University Surakarta. Experimental design used completely randomized design with 9 kinds of treatment was replicated 3 times. Experiments were the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations that are based on fulfilling nutrient requirements of 120 kg N ha-1.Result shows that the use of cow manure, Azolla fertilizers and Azolla inoculum had no effect on changes of soil fertility status. Soil fertility status was not significantly correlated with cow manure (0,16ns), Azolla fertilizer (0,26ns) and Azolla inoculum (0,16ns). Average of final soil fertility status included fertile category, which was similar as the initial soil fertility status. Average of final soil properties of treatment but nevertheless was relatively higher than in no treatment, indicating the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations had greater impact to soil properties. Cow manure despite increased available K2O and dry grain, but it did not significantly increase the soil fertility status from fertile to very fertile. This was presumably due to the relatively short experiment period, only one planting season had not given significant effect to soil properties. Implication of this study is the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations although did not increase the soil fertility status but could maintain soil fertility status as the initial conditions before planting.
