Get PDFMinarsih S, Samijan S, Arianti FD. 2020. Increasing the availability of phosphate in acid soils through inoculation of phosphate solubilizing bacteria and adding organic matter to the soil. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Phosphate is one of the macro elements whose availability is limited in acid soils because it is bound by soil minerals. Phosphate solubilizing bacteria are able to dissolve phosphate bound by soil minerals so that its availability increases, the addition of organic matter is also able to increase the availability of phosphate through organic acids resulting from its decomposition. This study aims to determine the types of phosphate solubilizing bacteria and kinds of organic matter that can increase the availability of phosphate in the soil. The experiment was carried out in the greenhouse of Sebelas Maret University Surakarta. Using a completely randomized design with 2 factors. Factor I was the inoculation of Phosphate Solubilizing Bacteria consisting of 3 levels, namely without inoculation of phosphate solubilizing bacteria (I0), Bacillus subtilis inoculation (I1), and Pseudomonas fluorescent inoculation (I2). The second factor are the type of organic material consisting of 4 levels, namely: no organic matter (B0), rice straw (B1), Tithonia diversifolia (B2), and Leucaena leucochepala (B3). The results showed that the use of Tithonia diversifolia organic matter independently proved to be the most effective in increasing available P in the soil by 261%. Bacillus subtilis combined with organic rice straw was able to increase the availability of P by 169%, then followed by the combination of Bacillus subtilis with organic material Tithonia diversifolia was able to increase P by 155% and the combination of Bacillus subtilis with Leucaena leucochepala increased P by 23%
The Yield Gap Maize under Intensive Cropping System in Central Java
Get PDFThe study aimed to estimate the level of the yield gaps of maize in major producing areas, point out the causes of yield gaps in farmers’ maize fields, and identify opportunities to the existing yield gaps through management practices of maize production in Central Java. This is the strategy for closing the existing yield gaps to achieve food self-sufficiency in agricultural land. Methods to estimates the yield gaps should cover data sources on physical conditions (weather and soil), management practices, and smallholder shapes. The relevant methods for estimating actual yields (Ya), potential (Yp), and water-limited (Yw) were compared. The yield gaps of maize under intensive cropping systems in rainfed ecosystems resulted in significant differences in all cultivation situations. The lowland rainfed maize showed Ya, Yp, and Yw values of 5.57, 12.83, and 12.47 ton/ha, respectively. The major causes of the yield gaps include variety, land preparation, and water issues concerned with the limited water inputs
Evaluasi Lapang Rekomendasi Pemupukan Padi Sawah Berdasarkan Pemupukan Hara Spesifik Lokasi Berbasis Internet di Jawa Tengah Indonesia
Get PDFAt the recent, guide of Site Specific of Nutrient Management (SSNM) was developed by International Rice Research Institute (IRRI) in collaboration with Indonesia Agency for Agriculture Research and Development (IAARD) through online media based on internet website. To establish this recommendation technology, field evaluation of SSNM online application based on NM-Rice website was conducted. The assessment was conducted in Trayu and Dukuh Village of Banyudono Sub District of Boyolali District of Central Java Indonesia on dry season 2013 (May-September 2013). The assessment result showed that SSNM rice yield of about 63,2% of farmers in Trayu Village higher than FFP. Yield gap difference of SSNM online varied about 1-20% higher than FFP, whereas the others are almost similar until lower than FFP yield, by variation about 1-11%. The assessment of fertilizer recommendation in Dukuh Village showed that only about 33,3% of farmers cooperator have SSNM yield higher than FFP. Whereas, the others have SSNM online yield lower than FFP which its involved about 10% of farmers have similar yield between SSNM and FFP. An average of NPK rate of SSNM online in Trayu Village is lower than FFP. SSNM online rate for N fertilizer recommendation in this location are about 133 kg/ha (93,9% lower than FFP), P2O5 about 38 kg/ha (73,8% lower than FFP), and K2O about 38 kg/ha (14,5% lower than FFP). Whereas in Dukuh Village, N rate of SSNM online recommendation are about 131 kg/ha (109,7% lower than FFP), P2O5 about 31 kg/ha (29,3% higher than FFP) and K2O about 30 kg/ha (63,3% higher than FFP). Generally, fertilizer recommendation based on SSNM online have benefit about 4,43% from existing.</p

Rice Production with Jajar Legowo Planting System without Insertion on Irrigated Paddy Fields
No full textThe Jajar Legowo planting system brings many benefits regarding productivity and planting techniques. Applying Jajar Legowo varies depending on the level of understanding and ease of application. This study aims to determine rice production with several planting systems of Jajar Legowo without insertion (legowo) in irrigated paddy fields. This study compared a Legowo planting system in several types of legowo (legowo 2:1, 4:1, and 6:1) with the regular cropping system or squares. Observational data were analyzed using ANOVA at a 95% confidence level, followed by Duncan’s test if there was a significant difference. The results of the analysis showed that the Legowo planting system showed no significant. The highest production of 5.71 tons/ha of milled dry grain (MDG) was obtained in the square planting system, and the lowest was in the legowo 6:1 planting system (5.51 tons MDG per hectar)

Axillary shoots derived from shoot tips in in vitro mass propagation of Anoectochilus formosanus Hayata
Get PDFAxillary shoot proliferation in in vitro mass propagation of Anoectochilus formosanus was successfully established via selection of different explant types, accessions and culture media to plantlet acclimatization. In the initiation stage, shoot tips and Murashige and Skoog (MS) medium containing 1.5 mg l-1 N6-benzylaminopurine (BAP) and 0.25 mg l-1 α-naphthalene acetic acid (NAA) were determined as high potential explant and medium for axillary shoot regeneration of A-1 and A-2 accessions of A. formosanus compared to others. High axillary shoots up to 7.0 shoots per explant with 1.0 cm shoot height and 9.8 leaves per explant derived from shoot tip explants of A-1 accession were signifycantly induced and proliferated in MS medium supplemented with 1.25 mg l-1 BAP and 0.25 mg l-1 NAA. Higher root formation up to 2.4 roots per shoot and 1.0 cm root length of A-1 accession was easily prepared on Hyponex medium (2 g l-1 20N:20P:20K) containing 150 ml l-1 coconut water (CW). While high survival rate of acclimatized plantlets as high as 90.4 % was successfully done by planting them in plastic boxes containing a mixture of burned rice-husk and organic manure (1:1, v/v) after 2 months. In the study, it was also revealed that in in vitro culture of A-1 accession of A. formosanus showed higher response compared to A-2 accession in all in vitro culture stages. The successful established protocol expected can be applied for preparing high-quality planting materials for commercial purposes and developing new route of in vitro mass propagation for other species of A. formosanus
Improved Crop Management on Open-Pollinated Maize (OPV) in The High Upland of Central Java Indonesia
No full textIn the highlands of Central Java, maize remains a staple food, but low yields are common due to limited use of local varieties and cultivation techniques. To address this, a study was conducted in Bojong District, Central Java, focusing on intensified maize cultivation through improved varieties, spacing, and fertilization. On-farm experiments were carried out, comparing different treatments with recommended practices. Sukmaraga maize showed the highest yields when following suggested spacing and fertilization, outperforming local yellow and white varieties significantly. The study revealed that intensification using high-yielding varieties and proper techniques could increase maize yields by 108-172% for different varieties. For local yellow and white maize, the yield increase was about 134% and 113%, respectively. Overall, adopting high-yielding varieties and improved techniques resulted in a remarkable average yield increase of 135% compared to traditional farmer practices. This research highlights the potential to enhance maize productivity in the Central Java highlands and improve food security in the region
