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

A field experiment was conducted to identify the best adapted and high yielding lentil variety at Shishinda sub-testing site of Bonga Agricultural Research Center during 2012 main cropping season. The experiment was carried out in randomized complete block design with three replications. Eleven improved lentil varieties were used for this study. The varieties included in the study were Teshale, Alemaya, Alemtena, Assano, Gudo, EL-142, R-186, Ada’a, Derso, Chalew and Chekol. The parameters studied in this experiment were days to flowering and maturity, plant height, number of pods plant-1, number of seeds pod-1, thousand seeds weight and grain yield. The analysis of the experiment showed significant (p<0.05) differences among varieties for all studied parameters. The varieties Assano, Alemtena, Derso, EL-142, and Gudo were found to be high yielder with the value of 1.71, 1.59, 1.39, 1.36 and 1.31 ton ha-1, respectively. In addition, farmers were invited to evaluate the performance of the tested varieties under field condition. Eventually, the farmers selected Assano and Alemtena as the most preferred varieties. Therefore, these varieties can be suggested to use for wider production in the study area. The involvement of farmers in variety selection processes may increases the adoption of new variety in the area. Int. J. Agril. Res. Innov. Tech. 9(2): 9-14, December 2019

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.

Quality Protein Maize (QPM) is a special maize functioning as source of carbohydrate and protein, which contain protein components lysine and tryptophan higher than that of normal maize. Experiment was carried out to evaluate the combining abilities of inbred lines introgressed with opaque-2 mutant gene and their hybrid performances on grain yield and other agronomic characters. Genotype test consisted of eight lines, eight testers, sixty four hybrid crosses between lines x tester and four check varieties. The experiment was arranged in a randomized complete block design, with two replications, on the lowland in Walenreng (Bone) and on dry land in Bajeng (Gowa). Variance analyses were done following the line x tester model. Results showed that the effect of genotype x location interactions were significant for ear weight and yield characters. The grain yields of three lines showed positive and significant general combining ability those were Nei9008+o2-09 (L1), Nei9008+o2-14 (L3) and Nei9008 + o2-27 (L7), but for the tester was only MR10+o2-31 (T7). Another eight crosses were showing significant effect for specific combining ability, but only combination of Nei9008+o2-09 and o2+MR10-31 lines was significantly superior to all check hybrids.

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.
