Abstract

Sugarcane seeding is a conventional initial seed stage that begins based on the juvenile phase for the formation of the three main components of the plant, namely roots, stems, and leaves. Conventional sugar cane nurseries use explants from either bud chips or mules to grow buds. Initial testing is based on viability characteristics, and seed vigor index. In addition, explant growth is influenced by the genetic aspects of each material used. This research aims to (1) determine the viability, and index of sugarcane seeds, and (2) estimate the action of genes that influence each observed character. This research was carried out in June – July 2023. The research used a complete randomized block design with the treatment of sugar cane varieties, namely AMS Agribun (V1), AAS Agribun (V2), and Kidang Kencana (V3). The results showed that the agronomic characters for the number of leaves, and leaf length were significantly different from ? 5%, with standard deviation, and coefficient of variation values, respectively, reaching 0.0697, and 21.144 for the number of leaves, and 4.743, and 29.776 for leaf length characters. The characters for the number, and length of leaves have skewness, and kurtosis values of 0.816, and (-0.3079), and 0.416, and (-0.811), respectively. The AMS Agribun variety showed the best performance for plant height, leaf length, leaf greenness, and number of roots. The AAS Agribun variety showed the best performance for the character's number of leaves, leaf width, and leaf area. Meanwhile, the Kidang Kencana variety showed the best performance regarding vigor index, growth speed, germination capacity, and root length.

Abstract

Tobacco (Nicotiana tabacum L.) is a commercial crop that plays a role in the economy. Tobacco productivity can be increased by optimizing existing land. One component of tobacco cultivation that supports tobacco growth is the availability of quality planting material. The aims of this research are 1) To determine the growth response of tobacco plant seeds in several local and superior varieties and 2) To determine the growth rate of tobacco plant seeds in several local and superior varieties. It was carried out at the Experimental Garden of the Faculty of Agriculture, Animal Husbandry, and Fisheries from June to September 2023. The design used was a non-factorial randomized block design repeated 3 times, each treatment consisting of 4 samples. The treatments tested were 4 varieties of tobacco, namely Ico Lalo (V1), Ico Tempo (V2), Kemloko (V3), and Prancak-95 (V4), so there were 48 experimental units. The results of the research showed that the Kemloko 1 variety had the best seed growth for observed characters, namely plant height, 10,425 cm; stem height, 2,943 cm; leaf length, 6,475 cm; and leaf width, 4,483 cm. The description of the kemloko 1 variety shows that the level of location specificity is better than that of superior and local varieties according to the observed characteristics, namely plant height, stem height, leaf length, and leaf width.

Abstract

One way to get rice that can adapt to drought stress is by providing drought tolerance in the germination phase through seed invigoration with the “Seed Priming” method. The study aimed to determine the level of adaptation and the response of growth and production of PEG-primed rice under drought-stress conditions.  The research was conducted in two stages. Phase I was in the form of rice seed priming in PEG 6000 solution arranged in a Randomized Group Design (RAK), consisting of 5 treatments, namely treatment without priming as control, PEG priming 0 gL-1, 50 gL-1, 100 gL-1, and 150 gL-1 with the length of seed priming for 36 hours. Phase II was a priming test of production levels in the field from the selected treatments in Phase I. The data were then statistically analyzed using analysis of variance (ANOVA). The results showed that priming treatment using PEG 6000 for 36 hours with a concentration of 100 gL-1 gave the best results on vegetative growth (93% germination, seedling height 28, 27 cm, leaf length 19.11 cm, number of leaves 4 cm, and root length 4.08 cm). This concentration also gave the best results on generative growth (number of productive tillers 12, and grain weight 31.71 per clump), and increased the adaptation of paddy rice to drought stress conditions.

Abstract

Indonesia is the sixth largest cotton importer and the ninth largest cotton user in the world. Therefore, efforts are needed to form new superior varieties, starting with determining the performance of cotton as a candidate for the formation of new superior varieties.This research aims to obtain cotton seeds for seed multiplication the following year, producing good brown cotton performance based on agronomic characteristics and the best type of organic fertilizer in increasing the growth of cotton plants. This study was conducted at the KP. Faculty of Agriculture, Animal Husbandry, and Fisheries, Muhammadiyah University of Parepare from June to October 2023. This study used a randomized block design with five repetitions. The treatments used were 4 types of fertilizers, namely chemical fertilizers, cocoa shell waste compost, goat manure compost, and Eco Glasum organic fertilizer. Thus, there were 20 experimental units. The observation parameters observed and measured were plant height (cm), number of leaves (strands), number of generative branches, pollen phenotype and cotton stomata, and age of flower blooming (DAP). Observation data were processed using the SAS 9.0 and Minitab 14 applications. The results showed that agronomic characters were not significantly different except for the number of leaves. The type of eco glasum fertilizer showed the best performance for the characters of plant height, leaf greenness, number of flowers, number of flowers blooming. Direct selection using scatterplot shows the best eco glasum fertilizer on the character relationship between the number of flowers vs. leaf greenness (R = 0.049 + 2.305X) and the number of flowers vs. plant height (R = 1.427 + 36.57X). Eco Glasum is a modification of solid fertilizer consisting of three types of seaweed, namelyEucheuma cottoni, Glacilaria sp., Sargasum sp. and modified by the addition of natural ZPT (Plant Growth Regulators) which are then fermented.
