Ability of commercial Beauveria bassiana to suppress the brown planthopper attack by inducing resistance into different rice variety

Abstract. Liswandi A, Syahrawati M, Hamid H, Arneti, Rinaldi J. 2023. Ability of commercial Beauveria bassiana to suppress the brown planthopper attack by inducing resistance into different rice variety. Biodiversitas 24: 6704-6710. Beauveria bassiana (Bb) is one of the biological agents for controlling the Brown Planthopper (BPH), Nilaparvata lugens, which is generally applied directly to BPH. Nowadays, it is also used to induce resistance in rice plants; this ability has never been tested on commercial B. bassiana. The research aimed to study the effect of different rice varieties and induced resistance of commercial Bb on BPH and rice plants. The study used a Factorial Completely Randomized Design (FCRD). The first factor was the difference in rice varieties (IR 42, Cisokan, Batang Piaman), and the second factor was the soaking of the seeds and roots by commercial Bb (with commercial Bb, without commercial Bb). The results showed no interaction between rice variety and commercial Bb against BPH and rice plants. Commercial Bb reduced the attack intensity of BPH (13.31%); meanwhile, different rice varieties influenced BPH mortality, colonization, and plant growth. The Cisokan variety was better at suppressing the BPH population (45%) and suitable for colonization by commercial Bb. The IR 42 variety was more responsive than other varieties in accepting the presence of commercial Bb (16%).

Effect of land flooding in controlling weeds to several rice varieties in System of Rice Intensification (SRI)

Rice is still a main carbohydrat source for almost Asian people. The System of rice intensification (SRI) method is one effort in increasing rice production. In cultivating rice in this method, weed is the main problem. The research aimed to study the effect of land flooding to control weeds in rice field by using various rice varieties. The research was carried out in public rice field, Kuranji district, Padang, Indonesia. It was conducted from July-September 2019. A block randomized design was used as method in the study. The treatment was rice varieties: Batang Piaman, Panca Redek, PB 42, Batang Pasaman, and Saganggam Panuah. These treatments were replied to three times. The result showed 15 weed species were found in the experiment. According to Summed dominance ratio, Echinochloa crusgalli was the most dominant species in the field (28.05%). For plant height, Saganggam Panuah was the best variety (86.00 cm), and Batang Pasaman was the best one (20.50) for a number of the tiller.

Morpho-physiological screenings and molecular analysis of west sumatra rice genotypes under submergence stress

This study investigates the submergence tolerance level of 14 rice genotypes by morpho-physiological and molecular analyses of Sub1 alleles. IR64-Sub1 was used as a submergence tolerant check. The submergence screenings were conducted by submerging 14-days-old seedlings in water tanks for 14 days while molecular analysis was conducted using 14 Sub1 linked markers. The results showed that 5 tested genotypes, namely Inpari 48 Blas, Mundam Putiah, Batang Piaman, Banang Pulau and Pulau Sijunjung, recorded high survival rates (SR) of 80% to 100% under submergence stress. PCR-based identification of the Sub1 alleles confirmed that several tested genotypes carry Sub1A and Sub1C, but not all were expressed in their phenotypic performance towards submergence. IR64-Sub1 and Batang Piaman not only showed well-adaptation towards submergence by maintaining lower elongation (<20%) and less chlorophyll content change (TCC) (<30%) but were also equipped with the Sub1A allele. These genotypes potentially provide good phenotypic and genotypic performance under submergence stress conditions. Additionally, based on population structure analysis, these genotypes were grouped into 3 clusters, of which 35.71% are pure accessions, while the remaining 64.29% have admixture ancestry between populations 1, 2 and 3. The data in model-based population structure and UPGMA dendrogram supported that rice genotypes in this study have 3 well-differentiated genetic populations and admixtures. Most genotypes have a close genetic relationship with Nei’s similarity index ranging from 0.571 to 0.893.

Response of Swamp Rice Elite lines to Submergence in Early Phase of Tiller Formation

The development of swamp rice varieties tolerant to submergence is an important step in reducing the impact of floods that often occur in swamplands. The objective of this study was to evaluate the response of eight genotypes of swamp rice in the early stages of tillering to submergence stress. The experiment was carried out using a completely randomized design with three replications. Pots filled with swamp soil were used as the growing media and a tarpaulin pond was used to submerge the plants. The swamp rice lines evaluated were UBPR 2, UBPR 6, UBPR 7, UBPR 8, UBPR 10, and UBPR 11 with Inpari 30 variety as the resistance check variety and Batang Piaman variety as the susceptible check variety. The results showed that the genotypes had varying degrees of growth recovery following the exposure of 10 days of submergence stress.    UBPR 7, UBPR 8, UBPR 10, and UBPR 11 tend to recover faster than other genotypes, classified as tolerant based on plant height, and the number of leaves and leaf greenness are moderately tolerant

Comparing the Genetic Parameters of Three Rice Varieties on Suboptimal Land Using the SRI Method

The conversion of fertile land into industrial areas and construction development has contributed to the decline of rice production in Indonesia. Therefore, it is necessary to expand the rice fields to the sub-optimal land, i.e. lands with high levels of Fe and Al and low soil pH. One of the solutions that can potentially solve the problem is choosing varieties of rice that can adapt to the suboptimal land environment; the rice varieties can be obtained by estimating rice genetic parameters and selecting the optimal planting methods. One method that can potentially improve rice yield is “System of Rice Intensification”, or SRI method. Our study was conducted in the rice fields on suboptimal land at Pasar Ambacang, Kuranji District, Padang, Sumatra, from December 2019 to April 2020. The aims of the experiment are to determine the genetic parameters and responses of the three rice varieties to suboptimal land using the SRI method. A complete randomized design with four replications was used to set up the experiment using three varieties of rice, i.e. “Batang Piaman”, “Bujang Marantau”, and “IPB3S”. Based on the plant growth measurement and analysis of the genetic parameters, we found that the plant growth characters, particularly height and panicles length, had high heritability and genetic progression values.

Abstract. Zarwazi LM, Junaedi A, Sopandie D, Sugiyanta, Purwono, Sakagami J-I. 2022. Prospective rice varieties for high yield performance on modified ratoon salibu cultivation. Biodiversitas 23: 1065-1071. Modified Ratoon Salibu (MRS) differs from ratoon (Conventional Ratoon, CR). This research aims to investigate some rice varieties re-grown as CR and MRS after main crops are harvested. The experiment was conducted at Kuningan Experimental Station of Indonesian Center for Rice Research, using rice varieties as the main plot (Hipa 18, Hipa 19, Inpari 42, Inpari 43, IPB 3S, and Batang Piaman), and ratoon cultivation system as a sub-plot (CR and MRS), evaluated in the first (1) and second (2) generation after the main crop. The result showed that the growth character of MRS on plant height, stem diameter, blade-leaf size, root volume was significantly higher than that of CR. Furthermore, the yield component and yield were also significantly higher in MRS than CR. The CR yielded about 56.9 and 10.8 % of the main crops for R1 and CR2, respectively, whereas MRS yielded 121.0 and 93.8% of the main crops for MRS1 and MRS2, respectively. This finding could be a scientifically proven of local wisdom “Salibu” indigenous knowledge in Tanah Datar District of West Sumatra, Indonesia. Therefore, MRS could be recommended for suitable varieties and environmental conditions as the sustainable farming alternative to increase Cropping Index while still reaching high productivity.

The Effect of Oil Palm Empty Fruit Bunches on Rice Production (Oryza sativa L.) With a Flood Height of 10 Cm Below Soil Surface

Improper processing of rice field systems and lack of organic matter in the soil to meet the nutrient needs of rice plants resulted in low rice production. Increased production of rice plants can be overcome by giving compost of palm oil empty fruit bunches (TKKS) with the system of rice intensifications (SRI) method, because the organic matter contained in the compost can improve the physical properties of the soil. This study aims to obtain the best dose of empty fruit bunch (EFB) compost and to see its effect on the production of lowland rice (Oryza sativa L.) by using the modified SRI method. The research was conducted from January-April 2019 at the UPT Experimental Garden, Faperta, Riau University. This study applied a completely randomized design (CRD) consisting of 5 treatment levels. They are 0 gr.polybag-1, 50 gr.polybag-1, 75gr.polybag-1, 100 gr.polybag-1 and 125 gr.polybag-1. The results showed that giving empty fruit bunch (EFB) compost with the SRI method gave an effect on productive tillers, pithy grain per panicle and grain weight, but did not affect panicle exit age, harvest age, percentage of pithy grain per panicle and 1000 grain weight of pithy grain. The best treatment dose was found at a dose of 20 ton.ha-1 because it could increase several components of lowland rice production of the Batang Piaman variety.

Effects of Seed PEG Immersion And Hydration-Dehydration on Rice Physiological Quality

Storage of seeds really determines the storability and quality of seeds, because Long-term storage, the seeds will deterioration. Deterioration of seed quality (deterioration) is inevitable but can be slowed by good and proper storage. To maintain seed quality, proper storage methods need to be carried out. The deterioration of the seeds can be improved by seed PEG immersion and hydration-dehydration. The objective of this research is to obtain an appropriate invigoration method to improve physiological seed quality Method: In this research, we used factorial two factors, we examine the effects of PEG immersion and hydration-dehydration treatment on three rice varieties; Batang Piaman, PB42, and IPB3S. Results: The results showed that PEG immersion and hydration-dehydration of three cultivars interacted with the index value. Conclusion: Our findings indicate that the invigoration method significantly improves the viability and vigor of Batang Piaman from 50% to 70% and 46.67% to 70% (PEG immersion), respectively.

Response of Batang Piaman Variety of Rice Crops to Fertilizers in Suboptimal Rice Field

Suboptimal land is a problematic land for rice crop growth. This is because the nutrient content in the soil is very low but the content of iron or aluminium elements is so high, that causes toxicity to plants, and then inhibited plant growth. Therefore, it is necessary to add organic fertilizer to the soil, one of which is cow manure that is available at all times and easy to obtain. In addition to cow manure, kieserite is also important to be given into the soil because kieserite contains magnesium nutrients that are badly needed for plant growth. This research purposes to see the best response of rice plants of Batang Piaman variety to fertilizer given to increase growth and yield on suboptimal land. This study used Completely Randomized Design with 3 fertilizer treatments [100% inorganic fertilizer, cow manure 5 tons/ha+150kg/ha kieserite, and 10 tons/ha of cow manure without kieserite]. Each treatment is replicated 5 times. The data is analyzed with a variety of variance and if the results differ noticeably followed by Honestly Significant Difference [HSD] Post Hoc Test in level 5%. Observations had made on some quantitative parameters. From the results of the study obtained that the best response from rice plants of Batang Piaman variety is obtained in the treatment of cow manure 5ton/ha+150kg/ha kieserite that provides high growth of plants 90 cm and the total number tillers of rice as 34 stems and a yield of 6.52 tons/ha on suboptimal rice field.

The Effect of High Temperature on α-Amylase Enzyme Activity in the Germination of Several Rice Varieties (Oryza sativa L.)

High temperatures can affect plant morphophysiological changes and enzyme denaturation that can interfere with the germination process. This research aims to study the effect of temperature changes on the α-amylase enzyme activity of several rice varieties germination. The research applies Factorial Experiment in Completely Random Design, where the first factor is four levels of rice varieties, Anak Daro, Batang Piaman, Cisokan, and Inpari 30. The second factor is temperature level, 28 0C, 32 0C, 36 0C, 40 0C, 44 0C and 48 0C. Results showed that the activity of the α -amylase enzymes of the four varieties increased when the temperature increased to reach the optimal temperature, and denaturation began to occur above that temperature. The highest enzyme activity of α-amylase of Anak Daro, Cisokan and Inpari 30 varieties at 48 0C is 0,14 micromol, 0,365 micromol dan 0,191 micromol. In contrast the optimum enzyme activity of α-amylase of Batang Piaman variety at a temperature of 40 0C is 0,237 micromol and when the temperature rises to 48 0C a decrease in the activity of the α-amylation enzyme is 0,138 micromol. The variation in the activity of α-amylase enzymes in the four varieties is probably due to genetic differences and sucrose content. The Batang Piaman and Cisokan varieties can only germinate up to 36 0C, while the Daro and Inpari 30 varieties can germinate up to 40 0C.

The Effect of Fish Type and Variety on Growth and Results Through the Application of Minapadi-SRI

National food security must be maintained because the food need of the Indonesian population in the next few years will still continue to increase. Since there is no food diversification for their staple food, rice role will still dominate. More over, the conversion of irrigated rice fields functions is also increasing. This reality must be addressed with policies and the application of efficient lowland rice production technology so that it is still able to meet national food needs while the income of wetland rice farmers increase. This study, combined an experimental production technology and descriptive methods on the farmer income aspect institutional strengthening. The aim of the research is to increase the added value of irrigated rice fields, which area is believed to be increasingly shrinking, while on the other side still produce rice as the main national food and also produce the addition of animal food in the form of fish coulde. Data obtained in the previous study showed that combination of water dept of a 10 cm with 50 cm width is the best treatment for the development of rice and fish togethere. This treatment is used as well as basis for testing the MINAPADI-SRI pattern with more varieties and types of fish, which is expected to obtaine more practical and profitable combinations. The research was conducted in the Split plot design where fish species (Tawes, Mas, and Nila) as the main plot and the rice varieties (PB42, Batang Piaman, and Beras Merah) as sub plot. The results showed that the PB42 gave higher yield compared to two the other varieties where tilapia and goldfish were which maintained in the technically irrigated rice fields.
