Abstract:
This research is motivated by the difference between fixed figures and forecasts the potential rice harvest area in 2020 released by BPS-Statistics Indonesia as the official statistical provider in Indonesia. BPS-Statistics Indonesia forecasts the potential rice harvest area in the next three months based on observations of the rice growth phase. The assumption used by BPS-Statistics Indonesia to forecast is that the age of rice harvest is the same across regions. This assumption is thought to cause the 2020 rice harvest area forecast to be higher than it should be. This study aimed to test the average harvest age of rice between provinces in Indonesia. Rice harvest age data was obtained by converting the data of the rice growth phase from the Area Sampling Frame (ASF) survey. The comparison methods used thematic maps, descriptive statistics, F-test, and Cartesian diagrams. The results showed that the best provinces measured by high rice productivity and short rice harvesting age were East Java, DI Yogyakarta, Central Java, West Java, and Aceh. The province with the shortest average rice harvest age was East Java, while the longest was Central Kalimantan. Based on the F-test, several provinces had significantly different average rice harvest ages with a confidence level of 99%. Therefore, it is recommended that BPS-Statistics Indonesia consider the effect of spatial dependence in forecasting the potential for rice harvested area.

Abstract:
Abiotic stress in the form of shading and drought in maize cultivation on rainfed land among plantation crops reduces yield. Therefore, an efficient and adaptive technology package is needed in this growing environment. This study aims to: 1) determine the technical and financial feasibility of the technology package for shade and drought tolerant maize cultivation on rainfed dry land between plantation crops (coconut), and 2) obtain recommendations for shade and drought tolerant varieties. The study was conducted through three trials in two locations in Gorontalo Regency, Gorontalo Province, in 2019 and 2020. To determine the technical feasibility, a field experiment was carried out using a randomized block design method with the introduction of technology package for shade and drought tolerant maize cultivation as a treatment, using 12 hybrid and composite maize varieties. Experiment I had five treatments with six replications, experiment II had eight treatments with four replications, and experiment III consisted of nine treatments with three replications. To determine the financial feasibility, used the partial budget analysis method. The results showed that the technology package for introducing shade and drought tolerant maize cultivation technology was technically and financially feasible, so it was recommended to replace the existing technology. The introduced technology package could increased maize productivity by 72% from an average of 1.706,43 kg/ha to 2.939,45 kg/ha, compared to the existing technology. The change in the use of existing technology to the introduction of maize cultivation technology gave a rate of return (R) = 1,89. In addition, the value of the R/C ratio, B/C ratio, and MBCR were greater than 1. The income from the application of introduced technology was an average of Rp 5.256.815/ha, higher than the existing technology of Rp 2.029.720/ha. The maize varieties recommended for their adaptability and efficiency in areas under both shade stress and drought with a combination of application of the introduction technology package were JH27, HJ21, Nasa-29, NK Sumo, Bisi-18, and Sinhas.

Abstract:
Correlation and path analysis between yield components and grain yield may be useful to provide the basis for planning more efficient in the selection program to obtain high yielding soybean genotype. The objectives of the experiment were to investigate the most responsible yield components to grain yield of morphologically diverse soybean varieties. Fifteen soybean varieties were evaluated on dry land in Grobogan, Central Java during the late rainy season of 2019. The experiment was arranged in randomized block design with four replications. Each of the genotypes was grown in five rows of five meters long. Plant spacing was 40cm x 20 cm with two seeds per hill. Results showed that among the yield components, days to maturity, number of productive nodes, number of pods per plant and seed size were positively and significantly correlated with grain yield (r= 0.501, 0.533, 0.404 and 0.422). Except the number of productive nodes, the direct effect of days to maturity, number of pods per plant and seed size to grain yield as indicated by path coefficient were the highest, each was 0.711, 0.503 and 0.520 respectively. The direct effect of number of productive nodes and other yield component were small or negative. Base on both analysis soybean genotypes with high grain yield showed have earlier maturity (35 Pods/plant) and large seed size (>15 g/100 grain). Therefore, days to maturity, pod per plant, and seed size can be suggested for selection criteria in selecting high yielding soybean genotypes on dry land.

Abstract:
Low rice production can be caused by limited supply of high quality seeds. Physiological quality criteria of seeds can be seen from the value of viability and vigor of seeds. One effort that can be made to maintain or improve seed quality is seed coating technology. The research was carried out from November 2021 to January 2022 at the Technical Implementation Unit (UPT) for the Development by Rice and Palawija Seeds, Malang Regency, East Java. The experiment used a completely randomized design with four replications. Seed coating treatment consisted of (1) seeds without coating (control); (2) CMC 1,5% + liquid smoke 0,5% + CaCO3 8 g + gypsum 32 g; (3) CMC 1,5% + liquid smoke 0,5% + CaCO3 8 g + talc 32 g; (4) CMC 1,5% + 0,5% liquid smoke + 8 g CaCO3 + 32 g zeolite; (5) CMC 1,5% + liquid smoke 0,5% + CaCO3 8 g + dolomite 32 g; (6) CMC 1,5% + liquid smoke 0,5% + CaCO3 8 g + quicklime 32 g; and (7) CMC 1,5% + liquid smoke 0,5% + CaCO3 8 g + pumice 32 g. The results showed that the seed coating material CMC 1,5% + 0,5% liquid smoke + CaCO3 8 g + gypsum 32 g was the best treatment that was able to increase germination and maintain the vigor index of rice seeds. This treatment significantly maintained seed germination at 100% with a vigor index of 72,5%.

Abstract:
Plant density is one of important technology in accordance with increasing rice productivity. Its in line with higher plant population up to optimum value, however increasing density above the optimum value will resulting decreasing yield. The optimum plant population density depends on many factors such as environment, management practices and specific varieties. This study aimed to obtain response of high population density on growth and yield in some rice varieties. The study was designed using split plot design with three replications. The main plot was plant population density, i.e. 213.333 plant population per ha (jajar legowo 2:1 planting method); 376.470 plant population per ha (jajar legowo ganda 1 planting method); 571.428 plant population per ha (jajar legowo ganda 2 planting method). Subplot was varieties i.e: Mekongga, Inpari-30 Ciherang Sub-1, and Inpari-32 HDB. The results showed that a high population density through jajar legowo ganda 2 planting method could increase the yield of Mekongga 16.31% and Inpari32 HDB 20.17% compared to jajar legowo 2:1 planting method, while Inpari-30 Ciherang Sub-1 had no significantly different between those two planting method. Therefore, the optimum irrigated rice yield could reach with plant density arragement and specific variety.

Abstract:
Increasing rice productivity on tidal swamp area need to meet available and affordable technologies. Plant population arrangement through planting method is the one of the cultivation technology which not widely adopted yet by farmers in tidal swamp ecosystem. Farmers generally used scattered plant arrangement called hambur. The research was conducted on tidal swamp type B at Karang Agung’s Experimental Field and farmer’s field in Sukaraja Village, Tungkal Ilir District, Banyuasin Regency, South Sumatera, 2018. The experiment was arranged by using split plot design with three replications. The main plot was rice variety (consisted of Inpara-2 and Inpara-8) and sub plot was plant population consisted of [1] Farmer’s practice (hambur/scattered), [2] Legowo 2:1 (213.333 population/ha), [3]Jarwo ganda 1 (376.470 population/ha), and [4] Jarwo ganda 2 (571.428 population/ha). Plant population arrangement in tidal swamp area was significantly effected by location and variety. Legowo 2:1, jarwo ganda 1 and jarwo ganda 2 had significantly higher yield than hambur. Hambur showed higher panicle number per m2 but lower grain filling ability and grain number per panicle. Through plant population arrangement, farmers could reached higher yield and saving seed consumption. Meanwhile, Inpara-2 tended to be more adaptive to population arrangement than Inpara-8. The jarwo ganda 1 with 376,470 plant/ha showed the highest yields for the Inpara-2 variety. Furthermore, we need to identify simple mechanization to help farmer for sowing by adopt plant population arrangement in tidal swamp land

Abstract:
Consumption of high nutritional is increasing; therefore, it is necessary to develop pigmented trice variety with high yield, good adaptability, and good grain quality favored by consumer such as soft texture. The development of aromatic rice variety includes crossbreeding, selection, yield trials, resistance test to pest and diseases, physico-chemical properties assay, analyzing of minerals contents and anthocyanin which were done consecutively during 2012 to 2016. The results showed that a promising line of BH39D-MR-11-1-1-6 revealed consistent grain yield in 16 multi-location yield trials both in the dry season and the wet season in average 6.78 t/ha dan 5.35 t/ha, respectively. The line demonstrated its yield potential of 10,67 t/ha, mid-resistance to biotype 1 of brown planthopper, resistance to pathotype III and mid-resistance to pathotype IV and VIII of bacterial leaf blight, and mid-resistance to four races of rice blast (race of 033, 073, 133 and 173). This line had relatively comparable iron content with the check variety of Inpari-5 Merawu but higher in zinc content compared to other lines tested. The dehulled rice was red and contains a high total phenolic compound amounting (5,743 mg AAE/100 g), and its texture was soft and fragrance. The BH39D-MR-11-1-1-6 has been released as new rice variety named as Inpari Arumba and had a great potential to become a national specialty rice choice.
