Increasing rice production in isolated areas of the Central Halmahera District, North Maluku Province, is expected to strengthen food security as well as increasing farmersâ€™ income. The objective of the study was to identify technology for increasing rice productivity in the lowland rice farming. An experiment was conducted at Sumbersari Village, Central Halmahera District, North Maluku Province, from July to October 2010. Four treatments consisted of four high yielding rice varieties (Inpari2, Inpari3, Inpari7, and Silugonggo) were cultivated applying the integrated crop management (ICM) and one variety (Cigeulis) was grown applying the local farmerâ€™s practice as control. The experiment was arranged in a randomized complete block design with three replications. Results showed that yield of cultivar Inpari 2 (7.15 t harvest dry grains (HDG)/ha), Inpari 3 (6.29 t HDG/ha), Inpari 7 (6.35 t HDG/ha), and Silugonggo (5.23 ton HDG/ha) were higher than that of Cigeulis variety (4.69 t HDG/ha). The R/C ratios of the ICM was higher than that of the conventional crop management, namely for Inpari 2 1.95, Inpari 3 1.72, Inpari 7 1.75, and Silugonggo 1.43, whereas the non-ICM (Cigeulis) was 1.49. The seed advantage value for the respective varieties was 2.14, 1.62, 1.65, and 1.02, respectively, each was higher than 1. This study indicated that introduction of new varieties into the ICM system increased rice productivity by 0.54-2.46 t/ha and increased farmersâ€™ incomes by Rp 1 to 3 million/ha. This meant that the adoption of new rice variety applying the ICM system in Central Halmahera, North Maluku, could be recommended for increasing rice production and farmersâ€™ income.

The experiments were conducted to study the genetic yield potential of six inbred lines and to develop superior hybrid of Provit-A maize. A diallel cross combinations including parents were conducted at Maros experimental farm in two seasons of 2009. The first experiment was to generate diallel F1â€™s between inbred parents, followed by the evaluation of General Combining Ability (GCA) and Specific Combining Ability (SCA) among inbred lines. The experiment used a randomized complete block design with two replications, tested 21 genotypes consisting of six parents and 15 F1 crosses. Griffingâ€™s model II was applied without reciprocal crosses, and the data were analyzed using the MSTATC program. The second experiment was conducted from August to November 2009. The results indicated that GCA and SCA effects were significant. The best SCA was obtained from cross of KUI Carotenoid Syn-FS25-3-2-B-BxCML305-B-B (P4xP6) and from KUI Carotenoid Syn-FS25-3-2-B-BxCarotenoid Syn3-FS5-1-5-B-B (P4xP5). Mid parent heterosis (MPH) was 254% and 260% and yield was 11.0 t/ha. The best GCA was indicated by KUI Carotenoid Syn-FS25-3-2-B-B (P4).

Soil salinity has negative effect on crop growth andÂ crop productivity. Information on the response of groundnut varietiesÂ to salinity is required for varietal selection adaptable to saline Â soil condition. The research was conducted at the greenhouse ofÂ Indonesian Legume and Tuber Crops Research Institute (Iletri),Â Malang, East Java from July to September 2013. The objective ofÂ the research was to study the effect of salinity on groundnut growth.Ten groundnut varieties, consisted of seven varieties of SpanishÂ type and three varieties of Valencia type, were tested on six levelsÂ of soil salinity. The treatment combinations were arranged inÂ randomized complete block design, replicated four times. TheÂ soil salinity level was obtained by treating soil media using seaÂ water dilution. Observations were made on electrical conductivityÂ (EC) of the soil, plant height, leaf chlorophyll content index, shootand root dry weight, number and dry weight of pods, and numberÂ and dry weight of normal seeds. Results showed that increasingÂ the salinity level inhibited both vegetative and generative growthÂ and the critical age to the plants affected by salinity was 45-65days after sowing. All variables of plant growth and yieldÂ components decreased with the increase of salinity level. TheÂ highest EC value of the soil for groundnut planting to produceÂ pods and seeds was 1.60-1.84 dS/m. Based on the growth variables,Â varieties of Valencia-type semed to be more tolerant to salinityÂ than did Spanish-type, but there was no tolerance difference basedÂ on crop yield and yield components between the two groundnutÂ groups. Higher tolerance of Valencia type was probably due to itsÂ ability to absorb and translocate more K in saline conditions.Â Among the Valencia type varieties tested, Domba variety indicatedÂ the most tolerance.

Information on genetic diversity of QPM and Provit-A maize germplasm is important to support breeding program, in order to form a high yielding maize hybrid. Simple sequence repeats (SSR) have been extensively utilized as genetic markers to study the genetic diversity, cultivar identification, and gene mapping. The objectives of this research were to investigate the genetic diversity and to obtain information the genetic relationship among 20 maize accessions using 29 SSRs. The research was carried out at the Moleculer Biology Laboratory of Indonesian Cereals Research Institute (ICERI) in Maros, South Sulawesi. Twenty nine polymorphic primers that covered the 10 maize chromosomes were used to fingerprint the genotype of the lines, detecting 83 allels, with an average allel number of 3 allels per locus, ranging from 2 to 6 alleles per locus. The results indicated that polymorphism information content (PIC) ranged from 0.10 (nc133 and phi072) to 0.74 (phi064) with the average of 0.45. Genetic distance based on genetic similarity estimate ranged from 0.39 to 0.92. The high level of PIC values and wide genetic distances indicated the large variability among maize germplasm. Cluster analysis divided the 20 maize accessions into three groups. Coefficient cofenetic value (r) was 0.85 indicated a good fit based on the genetic similarity value. As many as 30 inbred heterotic recombinants were derived by incorporating 20 QPM and Provit-A with genetic distance of â‰¤0.65. The SSRs proved to be reliable and is practical technique for revealing the relationship among specialty maize genotypes.

Tanaman padi memiliki peran politik sebagai tolak ukur keberhasilan pemerintah di bidang pertanian. Pemerintah daerah membutuhkan data produktivitas tanaman padi hingga level kecamatan untuk mendukung program swasembada pangan. Permasalahannya, BPS tidak dapat menyajikan data produktivitas tanaman padi hingga level kecamatan karena ukuran contoh pada Survei Ubinan tidak representatif untuk penyajian data hingga level kecamatan. Tujuan dari penelitian ini adalah melakukan pendugaan data produktivitas tanaman padi dan produksi beras per kecamatan di Kabupaten Seruyan Provinsi Kalimantan Tengah Tahun 2016. Kabupaten ini dipilih karena memiliki lahan menganggur yang besar mencapai 479ribu hektar. Metode yang diajukan untuk menyelesaikan permasalahan di atas adalah menggunakan Geoadditive Small Area Model. Keakuratan pendugaan akan dievaluasi dengan nilai RMSE (Root Mean Squared Error) menggunakan metode jackknife dengan proses resampling. Hasil penelitian menunjukkan produktivitas tanaman padi di Kabupaten Seruyan memiliki kecenderungan bahwa semakin ke hilir Sungai Seruyan maka produktivitas tanaman padi menjadi semakin besar. Produktivitas padi tertinggi berada di Kecamatan Seruyan Hilir Timur (34.58 ku/ha) dan terendah di Seruyan Hulu (19.93 ku/ha). Hasil dugaan dengan model Geoadditive Small AreaÂ memberikan hasil yang akurat dengan nilai RMSE yang kecil. Dari seluruh kecamatan di Kabupaten Seruyan, hanya empat kecamatan mengalami surplus berasÂ yaitu Kecamatan Seruyan Hilir Timur, Danau Sembuluh, Seruyan Hulu, dan Suling Tambun sedangkan enam kecamatan lainnya mengalami defisit kebutuhan beras. Secara keceluruhan, Kabupaten Seruyan selama tahun 2016Â mengalami defisit kebutuhan beras sebesar 8 236.80 ton.Kata kunci: Produktivitas padi, Geoadditive Small Area Model, Surplus/ defisit beras.

Increasing of significant population also resulted in increased national food needs. Conversion of arable land into non-agricultural land make suboptimal lands became the target of planting areas to fulfill food security. Swamp land is one of suboptimal land which potential to be developed. Swamp land in Indonesia (33.40 to 39.40 million ha) has a huge potential to support the stability of the national rice production. In addition to abiotic stresses, biotic stresses also often occurs in swamp lands. This study aims to select the lines which have high yield and resistant to bacterial leaf blight (BLB). This experiment was conducted at Muara, Bogor in April-September 2014. The materials are 318 lines with five check varieties namely Inpara 2, Inpara 3, Inpara 6, Inpara 7, and IR42. The experiment was arranged in a augmented design. Observation were made on plant height, tiller number, age of flowering, age of maturity, yield, scores of bacterial leaf blight (BLB), and a score of phenotypic acceptability (PACP). Data were analyzed using SAS version 9 for analysis of variance and continue with path analysis and weighted standardized selection index. The results showed that there were sixty lines selected based on weighted standardized selection index. The lines have a yield between 4.48 to 7.48 t / ha and promissing to the next test. Three lines have yield which significantly higher than Inpara 2 namely B13100-2-MR-2-KA-3-2 (7.48 t / ha), TDK-Sub 1 1- MR-1 (7.04 t / ha), and B13991E-KA-25 (6.98 t / ha). TDK-Sub 1 1- MR-1 and B13991E-KA-25 also have resistance to bacterial leaf blight.

One alternative to accelerate the decomposition of lignin or cellulose organic matter is to use microorganisms. BacterialÂ combined with fungi and synergistic will produce good compost. To ensure the viability and effectiveness of the decomposer microorganisms a suitable carrier material is required. The objective of the study were to obtain a combination of microorganisms isolates (bacteria and fungi) in accordance with the formulation of the carrier in supporting their viability and effectiveness to decomposting of maize biomass. The results showed that the combination of isolatesÂ E7.7 + P7 and B7.1 + O5 up to 28 weeks' storage were relatively superior than Promi and EM4. At 28 weeks storage,Â population of bacterial E7.7+P7Â is 2,1-2,75x109 cfu/g and fungusÂ 0,3-0,48x109 cfu/g, isolate B7.1+O5 had bacterialÂ Â 1,38-2,5x109 cfu/g and fungusÂ 0,2-0,3x109 cfu/g. While Promi and EM4 had bacterial were about 0.1-1.5x109 cfu/g and fungus 0.1x109 cfu/g. Both of these isolateÂ Â to decomposition of maize biomass had lower C/N and water content, and higher P and K content than EM4. Therefore, both of the combination of bacteria and fungi (E7.7 + P7 and B7.1 + O5) are worthy to biodecomposer for the making of compost fertilizer. To maintain viability and effectiveness of microbe E7.7+P7 was a better to use sago+compost, while for the combination of B7.1+O5 can using sago+compost and alternative is rice water+zeolit carrier material. The results of identification based on 16S rRNA sequence showed that isolates B7.1 and E7.7, respectively were Bacillus cereus strain ATCC14579 and Brevundimonas diminuta strain NBRC12967, while isolates of fungus O5 and P7 respectively were are Aspergillus fumigatus strains KARVSO4, and Aspergillus fumigatus strains DAOM-21534-28S.

Almost the entire planting of soybean commodity on Sumatra island has decreased. Mostly due to the low soybean productivity so that soybean farming is less attractive and encourages many farmers to switch to other commodities such as corn, peanuts and cassava. The low productivity of soybean is also due to limited capital to buy production facilities in the form of seeds, fertilizers and pesticides while the price of production facilities which from year to year tend to increase, especially the price of artificial fertilizers and pesticidesÂ Besides, the price of soybean during the harvest time is not stabilized and often less profitable farmers. This study aims to measure the level of economic efficiency that includes technical efficiency and allocative efficiency (price) in soybean farming in East Lampung, so it is expected to know the influence of the number of inputs used in soybean farming on the resulting output. Analytical methods used technical efficiency analysis using Data Envelopment Analysis (DEA) application, cost / allocative efficiency analysis and economic efficiency analysis. The results showed that the average technical efficiency of soybean farming system = 1 means that in general the soybean farming has reached the level of technical efficiency. The average value of the allocative efficiency of 1,4 means that on average the allocative efficiency level of oybean farming has not been achieved. The value of economic efficiency 1.4 is greater than 1. This means that maximum economic efficiency in East Lampung regency has not been achieved, therefore the use of production factors need to be added in order to achieve efficiency condition.
