Increment of upland rice production in Indonesia faces many problems mainly from kresek caused by Xanthomonas oryzae pv. oryzae and blast caused by Pyricularia grisea. The use of Liquid Organic Fertilizer (LOF) and liquid smoke provides an alternative method to control the pathogen. This research aimed at knowing the potency of the leaf fertilizer applied to the soil and the liquid smoke to control the disease in G136 line’s rice and on the crop growth. Randomized Block Design was used with six treatments and replicated four times. The treatments were control without liquid smoke, control with 2% liquid smoke, using 2 ml l-1 LOF Biosena without or with 2% liquid smoke, and using 4 ml l-1 LOF Biosena without or with 2% liquid smoke. The variables observed were incubation period, disease intensity, infection rate, crop height, number of shoots, weight of 1,000 grains and rice production per hectare. The result of the research showed that treatment using the leaf LOF applied to the soil of 4 ml l-1 or 2 ml l-1, and combining with 2% liquid smoke was not able to suppress the kresek and blast development in G136 line. All treatment influenced the number of shoots and the crop height plants, but didn’t influence the weight of 1,000 grains and the rice production per hectare.Peningkatan produksi padi gogo di Indonesia menemui banyak kendala di antaranya adalah penyakit kresek yang disebabkan oleh Xanthomonas oryzae pv. oryzae dan penyakit blas yang disebabkan Pyricularia grisea.

Abstract The use of uncontrolled an-organic fertilizer continuously will degrade soil fertility and nutrients balance. To minimize those impacts, biofertilizers and an-organic fertilizer are needed to maintain a sustainable maize production system. The study used a randomized complete block design with 3 replications with different levels of fertilizer application, conducted at University of Brawijaya experimental research station at Jatimulyo-Malang-East Java. Several parameters were measured to examine those effects on soil and crops. The treatments affect crop height, leaf chlorophyll indices, leaf area indices, maize yields, total number, and mycorrhizal infection. The best treatment was detected under the combination of 100% biofertilizer and 100% NPK, along with the addition of 100% microelements. The lowest was observed under mycorrhizal applications. There was a positive correlation between chlorophyll, crop height, leaf area, and maize yields.

Rice is an important food crop for human population ranking second among the mostly consumed cereal grains worldwide. Upland rice production is greatly constrained by drought stress resulting from rainfall variation patterns. Cultivation of drought tolerant varieties is considered the best option for drought management in rice production. The already released upland rice varieties are drought susceptible and have poor grain attributes hence, the aim of this study was to determine the combining ability for drought tolerance in upland rice. Four upland NERICA and two upland rice varieties were selected as parents for generating F1s crosses following 6 × 6 complete diallel. The generated 30 F1 crosses were advanced to F2 population for field evaluation. The F2 progenies together with six parents were planted in two sites; KALRO-Mwea Center Farm and Kirogo research Farm following a randomized complete block design in three replications. Drought stress was initiated 45 days after sowing after which data was collected on drought and agronomic parameters. The study revealed large genetic variations among the genotypes used. Both GCA and SCA were significant indicating the importance of both additive and non additive gene action in the expression of studied traits. In this study NERICA 2 and NERICA 15 were identified as good combiners for drought tolerance and grain yield under drought conditions. The single crosses namely; NERICA 15 × NERICA 2, NERICA 1 × NERICA 15, NERICA 11 × NERICA 15 and NERICA 2 × NERICA 15 were identified as superior for improving yield under drought conditions.

Productivity of local upland rice varieties are usually low, making farmers refrain to cultivate upland rice. This resulted in the low contribution of upland rice in production. However, farmers are still planting upland varieties of rice because of their desirability and adaptation to the environment. Therefore, we always need to develop new varieties that have high production and flavors that suit the tastes of society. The key to increase production of variety is providing sufficient nutrients during the growing period. This study aims to accelerate the availability of nutrients of organic fertilizer for the production of new upland varieties with high productivity. The study carried out in two phases and three different locations. All stages of research was setup in the field using Grid Design Divided (split plot design). In the phase-1, we determined the dose, 5, 10, and 15 tons/ha of organic fertilizer, as well as the adaptability of new varieties (genotype JT-DR-G-416 and parental varieties Jati Luhur and Dayang Rindu). The results of phase-1 showed that best dose was 15 tons/ha. Then we proceeded to the phase-2, which aimed to determine the best management practice to provide organic fertilizers such as: C1= organic fertilizer spread directly on planting plots, C2 = organic fertilizer spread over the terraced planting, then sprayed EM-4, C3 = composted organic fertilizer spread on the plots before planting. The variables measured for the study at phase-1 and phase-2 included plant height (cm), number of productive tillers/hill, the number of grains/panicle, 1000 grain weight (g), percent grain hollow/panicle (%), and grain yield per clump (g). The results showed that the new variety/genotype JT-DR-G-416 can adapt better than both parents at upland field conditions. The production of JT-DR-G-416 was increased by 7.75%, when 15 tonnes/ha of organic fertilizers was applied. Application of composted organic fertilizer could increase production by 33.22%, compared to without compost. Application of organic fertilizers followed by giving a solution of microorganisms (EM-4) could improve upland rice production by 30.56 to 32.06%.

Identification of highly performing varieties under Senegalese environment is crucial to sustain rice production. Genotype-environment interaction and stability performance on the grain yield of ten upland rice genotypes were investigated across 11 environments in Senegal during the rainy seasons of 2016 and 2017 to identify adapted varieties. The experiment was conducted using a randomized complete block design with three replications at each environment. Data on grain yield were recorded and analyzed using the additive main effects and multiplicative interaction (AMMI) model. The combined analysis of variance revealed that the grain yield was significantly affected by environment (67.9%), followed by genotype × environment (G × E) interaction (23.6%) and genotype (8.5%). The first two principal component axes were highly significant with 37.5 and 26% of the total observed G × E interaction variation, respectively. GGE biplot grouped the environments into four potential megaenvironments. Based on the yield stability index parameter and ranking GGE biplot, NERICA 8 and ART3-7-L9P8-1-B-B-1 were stable and high-yielding varieties compared to the local check NERICA 6. These varieties should be proposed for cultivation in order to sustain the rice production in the southern part of the groundnut basin of Senegal and used as parental lines in rice breeding program for grain yield improvement.

Low rice yields in Nigeria are attributed to poor soil fertility. Inorganic fertilizers used to improve soil fertility are expensive and not readily available. This work aimed at evaluating the nutrient potential of rice husk and cassava effluent compost for production of rice in Abraka, Delta State, Nigeria. Four formulations were made with rice husk (RH) and cow dung in ratio 7:3 by weight using water and cassava effluent [RH with water (RH), RH + cow dung with water (RHCd), RH with cassava effluent (RHC), RH + cow dung with cassava effluent (RHCdC)] and were applied at 2.5, 5 and 10 t/ha with control. Rice seeds were sown for two years in a randomized complete block design. Residual effects were monitored in the third year. Plant height (PH), leaf area (LA), dry matter (DM) and rice grain yield (GY) were measured as well as soil samples were taken for post-cropping analysis. Data were analyzed with ANOVA at α0.05. The results revealed that treatment RHCd at 10 t/ha had highest PH and LA while RHCdC at 10 t/ha produced the highest DM and GY in both years and in residual study. Treatment RHCdC at 10 t/ha had the highest soil pH value, organic carbon and RHCd at 10 t/ha had the highest total nitrogen at harvest in second year. Both treatments increased soil nutrients at harvest than other treatments and improved soil fertility. Keywords: Soil amendment, cow dung, organic fertilizer, rice yield, Abraka.
