Bed Position

The alternating dry and flooded bedding system (Surjan) optimizes land availability, by integrating food crop culture in the lower bed and annual crops in the upper bed position, of the rainfed rice field. Rainfed rice productivity is generally low, to increase its productivity rice culture should integrate the management of crop, water and nutrients. Rice field is regarded as greenhouse gas sources, especially methane (CH4) and carbon dioxide (CO2). Field experiment was conducted in the rainfed rice field in Pati, Central Java, to determine GHGs emission and grain yield from three rice varieties, applied with cattle manure, planted in the rainfed rice field, using alternating beds system. The experiment was arranged in a randomized block design with three replicates and six treatments of the combination of cattle manure application and rice varieties. The rates of cattle manure were 5 and 30 t/ha, while rice varieties were Inpari 1, Inpari 6, Ciherang. Data observed included grain yield, soil pH, fluxes of CO2 and CH4. Combination of Inpari 6 with 5 t/ha cattle manure emitted GHGs higher than combination of Inpari 6 with 30 t/ha cattle manure, while GHGs emission from combination of Ciherang with 5 t/ha cattle manure was lower than combination of Ciherang with 30 t/ha cattle manure. Variety Inpari 1 emitted the lowest GHGs, both from the combination of 5 t/ha and of 30 t/ha. The average grain yield of Inpari 1, Inpari 6, and Ciherang in the rainfed lowland rice each was 6.27, 6.01, and 5.70 t/ha, respectively. The GHGs releases from the rice variety roots depend on the availability of organic matter in the soil that is used as energy source for GHGs forming microbes.

Different Altitudes

To evaluate high yielding drought tolerant rice varieties in different altitudes, a field experiment was carried out at Duradanda, Lamjung, Nepal during rainy season of 2016 under rainfed condition. The experiment was laid out in a factorial randomized block design with two replications. The treatments comprised of six different rice varieties viz. Sukhadhan-1, Sukhadhan-2, Sukhadhan-3, Sukhadhan-4, Sukhadhan-5 and Sukhadhan-6 and four altitudes viz. 1000, 1200, 1400 and 1600 masl. The results revealed that rice variety Sukhadhan-2 produced the highest grain yield (2.93 t/ha) followed by Sukhadhan-5 (2.92 t/ha) and Sukhadhan-3 (2.82 t/ha). The highest grain yield of Sukhadhan-2 was due to higher number of effective tillers/m2 (228), higher number of grains/panicle (83), higher panicle length (21.79 cm) and low sterility percentage (27.91%) as compared to other varieties. Regarding to altitudes, the highest grain yield (3.34 t/ha) was obtained in lower altitude (1000 masl) followed by 1200 masl (2.79 t/ha), 1400 masl (2.68 t/ha and 1600 masl (1.85 t/ha). The lower yield in higher altitude was due to higher sterility percentage, less number of effective tillers per unit area and less number of effective grains per panicle. It seems that the performance of these varieties was good up to 1400 masl.

Sixteen genotypes of rice (including one check) were evaluated on 18 quantitative traits during sali (August), 2018 in a randomized block design with three replications at Instruction cum Research Farm, Department of Plant Breeding and Genetics, Assam Agricultural University, Jorhat to study the nature and magnitude of variability, heritability and genetic advance under delayed sown condition. The analysis of variance for 18 quantitative traits revealed the presence of significant differences for grain yield and its component characters. The highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was observed for chaffs per panicle followed by grains per panicle, spikelet sterility (%), spikelets per panicle, grain yield (kg/ha). A high heritability coupled with high genetic advance was observed for plant height (cm), spikelets per panicle, spikelet sterility (%), chaffs per panicle, grains per panicle, grain yield (g/hill), grain yield (kg/ha), biological yield (kg/ha), straw weight (kg/ha) and harvest index (%) indicating that selection might be effective for improvement of these characters under delayed sown condition with low input. From the findings of this investigation, one genotype viz., Gandhari emerged as the outstanding genotype which yielded 4170 kg/ha and could be directly used for cultivation in delayed sown situation with low inputs. Some other promising genotypes that yielded higher than the check Manoharsali under delayed sown condition were JR 29, JR 16, Basundhara and JR 60 and could be utilized as potential parental material in the hybridization programmes designed to develop suitable rice varieties for delayed sown situation.

ABSTRACT The upland rice farmers in Suriname use local varieties and low level technologies in the field. As a result, the upland rice grain yield is low, at about 1 000 kg ha-1. Our objective was to evaluate the use of upland rice cultivars from Suriname and Brazil, and the effect of nitrogen, N, phosphorus, P, and potassium, K, fertilizers on cultivation variables. We undertook four field trials in the Victoria Area, in the Brokopondo District, using a randomized block design each with four replications. The most productive rice varieties were BRS Esmeralda (grain yield 2 903 kg ha-1) and BRS Sertaneja (2 802 kg ha-1). The highest grain yield of 2 620 kg ha-1 was achieved with a top dressing application of 76.41 kg N ha-1 20 days after sowing. For P, the highest grain yield of 3 085 kg ha-1 was achieved with application of 98.06 kg ha-1 P2O5 applied at sowing. An application rate of 31.45 kg ha-1 of K2O at sowing achieved the highest grain yield of 2 952 kg ha-1. Together, these application rates of N, P and K resulted in rice grain yield of about 3 000 kg ha-1, which is three times greater than the national average for upland rice. We demonstrate that the use of improved rice varieties matched to the local conditions, and application of appropriate fertilizers, are management practices that can result in significant increases in rice grain yield in Suriname.

The aim of the study is the effect of nitrous oxide (N2O) emissions on rice field. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Sriwijaya University, Indralaya Campus. The N2O gas analysis was conducted at the Laboratory of the Indonesian Agricultural Environment Research Institute, Ministry of Agriculture, Central Java. From April to July 2016. This study used a Randomized Block Design (RBD) with irrigation classes, namely 5 cm (A1), intermittent / intermittent (A2) plots, and saturated land (A3), divided into three (3) groups with a total of 18 treatments, so that there were 54 plots in total. Observation of N2O gas was chosen at weeks 2, 4, 6 and 8 after planting using a closed lid for 24 hours. N2O gas flux is calculated based on an equation adopted from the International Atomic Energy Agency (IAEA). The results obtained are the emission of N2O gas produced by maps with air saturation condition of 5 cm from the surface of the land (A3) in the amount of 1564,554 mg N2O / ha / day and the lowest is produced by inundated plots (A1) with a value of 648,996 mg N2O / ha / day. Soil conditions that are inundated during plant growth produce anaerobic soil conditions capable of lifting N2O flux compared to air-saturated conditions.

The effort to increase food production in tidal lowland areas was conducted by applying production technology through the use of superior varieties and organic fertilizer enriched with bacteria (bio organic fertilizer). This fertilizer was a formula that had been tested in swamp lowland area and proven capable to regain land fertility through action of beneficial microbia. Some microbia which used to produce bioorganic fertilizer are Azospirillium bacterium and phosphate solvent bacterium with carrier substance of chicken manure fertilizer. The reserach objective was to determine yield capacity of two rice varieties by using inorganic fertilizer and bioorganic fertilizer at tidal lowland area. This research was done at tidal lowland area of C-flooding type. The design used in this study was Factorial Randomized Block Design with 4 treatment combinations and 6 replications for each treatment. The first factor was varieties which consisted of Inpara 6 (V1) and Inpari I (V2), whereas the second factor was fertilizer types which consisted of inorganic fertilizer (P1) and bio-organic fertilizer (P2). The results showed that yield capacity of Inpari I rice variety treated with bio-organic fertilizer + 50% of recommended NPK fertilizer could increase the production of dry unhulled rice with magnitude of 165% (1.59 kg/plot or equal to 3.98 ton/ha) at tidal lowland of C flooding type. Through the provision of biofertilizers, chicken manure enriched with Azospirillum and bacteriophosphate biofertilizers contributes to sustainability agriculture, especially in tidal wetland

An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh in transplant Aman season 2008 to find out the effect of urea super granules (USG), prilled urea (PU) and poultry manure (PM) on the yield and yield attributes of transplant Aman rice varieties. Two transplant Aman rice varieties viz. BRRI dhan41 and BRRI dhan46 and ten levels of integrated nutrient management encompassing USG, PU and PM were tested following randomized complete block design with three replications. It was observed that variety BRRI dhan41 gave higher grain yield than BRRI dhan46. For fertilizer effect, the highest grain yield (5.17 t ha-1) was obtained from full dose of USG (1.8g) and other inorganic fertilizers, which was similar to that obtained from full dose of USG (1.8g) + PM at 2.5 t ha-1 followed by full dose of PU + PM at 2.5 t ha-1. The lowest grain yield was obtained in the control treatment. In case of interactions, the highest grain yield was obtained in BRRI dhan41×1.8g USG and other inorganic fertilizers which was similar to that of the same dose of USG with PM at 2.5 t ha-1 and the lowest yield was obtained in the control treatment. It was assessed that a considerable portion (31.25%) of PU nitrogen could be saved by using USG (1.8g) together with other inorganic fertilizers or with PM at 2.5 t ha-1.

The success of selection in plant breeding program is determined by genetic variabiliities, heritability values and the correlation between agronomic characters and yield. The study aims to determine the genetic variability, heritability and the effec of agronomic characters to grain yield. The experiment was conducted in February to May 2016 in Grobogan, Central Java. The experiment consists of twelve genotypes of maize hybrids, arranged in a randomized block design with three replications. The characters observed were plant height, ear height, number of harvested ear, shelling percentage, moisture content of grain harvested, weight of 100 grains, ear length, ear diameter, number of rows per ear, number of seeds per row per ear, and grain yields. The results showed that the genetic variability of agronomic characters was broad, except ear diameter. Almost all of the heritability values of yield components were high, except harvested ear weight and ear diameter. The characters of plant height, ear height and as the genotypic gave high of a direct effect on the yield higher, while direct effect of the phenotypic character of ear hairves on grain yield are higher.
