Bacterial wilt caused by Ralstonia solanacearum E.F. Smith is one of the destructive diseases of tomato. Experiments were conducted to confirm the resistance and to evaluate varieties received from Asian Vegetable Research and Development Center against bacterial wilt disease in the farmers’ bacterial wilt sick fields at Thaiba and at Panchkhal during 1999 and 2000-2001 respectively. A total of five varieties such as CLN 2026 C, CLN 2026 D, CLN 1466 J, CLN 1466 P and susceptible check Lapsigede or L 390 were included in the experiments. Randomized complete block design with 4 replications was commenced at both the locations. In terms of disease incidence and yield parameters as well as consumers’ preference on the fruit size, CLN 2026 C was found the best variety followed by CLN 2026 D. Wilt incidence was significantly lower in those varieties showing resistant reaction than in susceptible check. However, the marketable fruit yields were significantly higher with low wilt incidences in CLN 1466 P and CLN 1466 J also compared to susceptible check. But the large fruit size of those varieties was not acceptable to the consumers and the  growers. Thus, CLN 2026 C and CLN 2026 D could be used as resistant variety to minimize crop losses from bacterial wilt disease.Nepal Agric. Res. J.

Abstract Background Bacterial wilt caused by Ralstonia solanacearum is one of the most devastating diseases in tomato cultivation. This study aimed to evaluate the effect of Bacillus and Trichoderma isolates to manage the bacterial wilt disease. Main body of the abstract Field experiments were conducted in a randomized complete block design at Mwea and Kabete sites in Kenya. The treatments included 3 Trichoderma; 2 Bacillus isolates; a mixture of T1, T2, and T4; chemical standard; and distilled water as control. Trichoderma and Bacillus isolates were grown on sterilized sorghum grain and cow manure carriers respectively. Antagonist’s inoculation was carried out by dipping tomato plants for 30 min in each treatment suspension. Each treatment was then applied at a rate of 150 ml/plant hole and this was repeated after 35 days. All the treatments significantly reduced bacterial wilt incidence and severity at P ≤ 0.05 than the control at both sites. Trichoderma isolate T1, followed by Bacillus isolate CB64, was the best in reducing the disease incidence by more than 61.66 and 53%, respectively at both sites. Treatment CB64 and T1 had the highest reduction of R. solanacearum population in the soil by 93.17 and 92.07%, respectively. However, control had a pathogen increase of 20.40%. CB64 and T1 performed significantly better compared to the standard, while the mixture of isolates T1, T2, and T4 performed the poorest in all parameters. The treatments also increased the yield of tomato. Short conclusion Results from this study showed that Trichoderma and Bacillus isolates are effective biological control agents for use in management of bacterial wilt.

Advance Yield Trial on different Bhote type garlic genotypes collected from different districts of Nepal was carried out at Horticultural Research Station, Rajikot, Jumla for two consecutive years 2013/14 and 2014/15 to evaluate garlic genotypes suitable for the Karnali region of Nepal. Minimal work has been done in past on garlic, almost all of which centered at terai and mid hills that's why this study was carried out to select suitable bhote type garlic genotypes for high hill. Eleven different garlic genotypes were tested on Randomized Complete Block Design (RCBD) with three replication. Tested genotypes differed significantly for vegetative as well as yield parameters. During 2013, the highest bulb yield (47.41 t/ha) was recorded from ARM 01 followed by Mugu Local (47.01 t/ha), ARM 04 (46.98 t/ha), Kathmandu Local (45.41 t/ha), Chinese (37.91 t/ha) and the lowest from ARM 08 (20.1 t/ha). Similarly, during 2014/15, the highest bulb yield was observed from ARM 01 (50.32 t/ha) followed by Mugu Local (49.91 t/ha), Kathmandu Local (41.62 t/ha), Chinese (29.60 t/ha) and the lowest from ARM 05 (12.51 t/ha). Based on the average result of both years, ARM 01, Mugu Local, Kathmandu Local, ARM 04 and Chinese showed the better productivity ranged from 29.6 t/ha to 50.32 t/ha which are the promising garlic genotypes for the Karnali region of Nepal.

This study seeks to determine the effect of N fertilization method on ratoon lowland rice performance, to choose a fertilization method that provides high ratooned yield, and to assess its profitability adopting N fertilization method. The experiment lays out in a Randomized Complete Block Design with three replications and five N fertilization methods as treatments. Method of N application significantly affected the number of days to heading and maturity, plant height, leaf area index (LAI), number of productive tillers hill-1, panicle length and weight, number of filled and unfilled grains panicle-1. This method compensates cost of production of growing ratoon crop than those of the main crop. In fact, the highest profit (PhP25,564.80) was obtained in ratooned plants, which received 60 kg ha-1 N basal + 30 kg ha-1 N topdress application (T3) due to higher grain yield. Thereby, this is an appropriate option that provides high productivity and income for the ratoon growers.

Abstract. Ishthifaiyyah SA, Syukur M, Trikoesoemaningtyas, Maharijaya A. 2021. Agro-morphological traits and harvest period assessment of winged bean (Psophocarpus tetragonolobus) genotypes for pods production. Biodiversitas 22: 1069-1075. Winged bean (Psophocarpus tetragonolobus) is an underutilized crop in Indonesia. Winged bean varieties for pods productions not only must have high productivity and nutrient contents, but also have a long harvest period. This research aimed to evaluate agro-morphological traits and harvest period of eighth-generation winged bean genotypes. Twenty genotypes of winged beans were evaluated using randomized complete block design (RCB) with three replications in Bogor, Indonesia. Several qualitative and quantitative traits were evaluated from each genotype. The results showed that there were variations among winged bean genotypes which were based on qualitative traits as well as the color of stem, calyx, corolla, pod, and pod wings. Purple coloration in the calyx of P1 and H3U genotypes was known to correspond with the purple color in stem, corolla, pod, and pod wings. The highest yield among F8 genotypes was found in H2 (6.69 to ha-1), similar to P2. However, the longest harvest period among F8 genotypes was found in H1U-2 (78 days). This study revealed that harvest period had positive correlation with the leaflet size. Based on nutrient content, H3U and L2 were considered as the genotypes with the highest protein and fiber content respectively among F8 genotypes.

Main Effect

The objectives of this study were to determine the importance of simple and complex components of the interaction genotype × environment and to evaluate the adaptability and stability of Gália melon hybrids. Nine hybrids were tested in twelve environments of Rio Grande Norte State from 2000 to 2001. The experiments were carried out in a randomized complete block design with three replications. The statistical methods of Toler and Burrows, Wricke and AMMI (Additive Main effect and Multiplicative Interaction) were used to study the adaptability and stability. The complex component is responsible for most of the genotype × environment interaction for the yield and content of solids soluble of fruits. The environments associated with Mossoró and Assu municipalities are the most suitable to evaluate melon hybrids in the state. The hybrid DRG 1537 was the most likely to be grown in the Agro-industrial Complex Mossoró-Assu due to its stability, high productivity and high content of soluble solids.

ABSTRACT An experiment to evaluate comparative performance of various sunflower hybrids for yield and its related attributes was conducted at the Agronomic Research Area, University of Agriculture, Faisalabad, Pakistan, during autumn 2008. Twelve sunflower hybrids, i.e. G-101 (H1), DK-4040 (H2), SF-187 (H3), S-278 (H4), Hysun-33 (H5), FH-37 (H6), Ausigold-61 (H7), Ausigold-62 (H8), FSS-50 (H9), NX- 00989 (H10), NX-00997 (H11) and XIYU-12 (H12) were included in the trail. The experiment was laid out in randomized complete block design (RCBD), having three replicates with plot size of 5m x 3m. Statistical analysis of the data showed significant differences for all the parameters. It was observed that Hysun-33 showed greater plant height (148.47 cm) and achene per head (682.70) than all other hybrids, however in case of yield (3891.0 kg ha-1) and other related traits such as number of plants m-2, leaf area index, head diameter and 1000-achene weight SF-187 displayed better performance by recording values (6.87), (4.33), (18.62) and (49.11g), respectively, following Hysun-33 for most of the traits. From the results of experiment it can be concluded that the hybrids SF-187 and Hysun-33 showed high productivity and are best adapted to the climatic conditions of Faisalabad.

Most of the Indonesian population uses rice as main source of carbohydrates. The need for rice increases every year, but rice production and rice harvest area decreases every year. One way to overcome this problem is using new variety that has high productivity. This research aims to determine the agronomic characters that can be used as character selection and to select the best lines based on the character selection. The research was conducted at the Seed Teaching Farm Field of Seed Technology Study Program, Politeknik Negeri Lampung in August - December 2020. The treatment design was arranged in randomized complete block design with 1 factor (line), 3 blocks, and 3 replications. The treatments tested were 6 lines of rice plants assembled by Politeknik Negeri Lampung, namely B1, B2, B3, B4, K, L2 lines with 2 comparison varieties Ciherang and Gilirang. The characters observed were plant height, total number of tillers, number of productive tillers, flowering age and harvest age. The data from the observations were processed with SAS software and the analysis of real variance was continued by using Duncan's Multiple Range Test (DMRT) with an error rate of 5%. The results of this research indicate that the characters of the total number of tillers and the number of productive tillers can be used as a selection character and the lines that have superior characters are the K and L2 lines.Keywords: Rice Lines, Agronomic Character, Selection
