Abstract

The advantages of 'Crystal' guava in Indonesia provide opportunities for farmers to cultivate and increase their production. Various methods of cultivation have been developed to increase the production of 'Crystal' guava, one of which is the use of Growth Regulators. Paclobutrazol is a plant PGR that regulates flowering outside the harvest season so that the production of 'Crystal' guava fruit can be maintained. The purpose of this study was to determine the best concentration of the effect of Paclobutrazol treatment in increasing the flowering of 'Crystal' guava plants. The research was conducted from August 2021 to March 2022 in Rajabasa Lama 1 Village, Labuhan Ratu District, East Lampung Regency. The treatment was carried out in a factorial manner using a single factor randomized block design with three replications so that 36 experimental units were obtained. The first factor was Paclobutrazol (A) which consisted of 6 treatment levels, there are A1 (0 ppm), A2 (4000 ppm), A3 (6000 ppm), A4 (8000 ppm), A5 (10,000 ppm), A6 (12,000 ppm). Paclobutrazol treatment with a concentration of 10,000 ppm gave the best results on the variables of flower number, number of ovules, number of harvested fruit and weight of harvested fruit. Keywords : Paclobutrazol, Concentration, ‘Crystal’ Guava Plants

Abstract

The presence of pulp in cocoa seeds is known to inhibit seed germination and seedling growth. The conventional method of removing pulp from cocoa seeds is done mechanically by rubbing the seeds with rubbing ash. Conventional pulp removal has disadvantages, such as being less practical and potentially damaging the seed surface. Therefore, it is necessary to try chemically removing the pulp from cocoa seeds by soaking the seeds in a lime solution (CaCO3). This study aims to determine the effect of the duration of cocoa seed soaking in CaCO3 solution and different planting media compositions on seedling growth. The research was conducted from September to December 2021 at a plastic house in Labuhan Dalam Village, Tanjung Senang District, Bandar Lampung, and the Seed Laboratory, Faculty of Agriculture, University of Lampung, Gedong Meneng, Bandar Lampung. The study used a Completely Randomized Design (CRD) arranged in a factorial manner. The first factor was the duration of cocoa seed soaking in CaCO3 solution, consisting of no soaking, soaking for 30, 60, 120, and 240 minutes. The second factor was the planting media composition, consisting of a mixture of rice husk charcoal + manure, sand + manure, and sand + rice husk charcoal + manure. Each treatment combination was replicated three times, resulting in 45 experimental units. The observation data were analyzed using analysis of variance, and the mean differences were tested using the Least Significant Difference (LSD) test at the 5% level. The results of the study showed that the duration of cocoa seed soaking in CaCO3 solution had no effect on cocoa seedling growth. The planting media composition of sand + rice husk charcoal + manure had a significant effect on the best cocoa seedling growth compared to the planting media compositions of rice husk charcoal + manure and sand + manure. Soaking cocoa seeds in CaCO3 solution had no effect on cocoa seedling growth in different planting media. Keywords : Cocoa seeds, pulp, CaCO3, soaking, planting media

Abstract

Shallot is an important commodity, but their productivity in Indonesia is still low. TSS can be used because of its higher production, longer shelf life, more resistance to disease pathogens, cheaper procurement and distribution costs, guaranteed seed quality, and high productivity potential, but has a small shape so it is difficult to plant so seed coating technology is needed. Seed pellets are coatings of seeds to change the shape, size and weight of seeds. This study aims to determine the effect of pelleting techniques on shallot seeds. This research was conducted with one treatment factor, namely without pelleting, soil + CMC, soil + CMC + Mycorrhizae, soil + CMC + Trichoderma, soil + CMC + Dolomite, soil + CMC + humic acid, soil + AG, soil + AG+ Mycorrhizae, soil +AG+Trichoderma, soil+AG+Dolomite, soil+AG+Humic acid. Each treatment was carried out with 3 replications so that 33 experimental units were obtained, with one experimental unit in the form of a planting media tray with 25 seeds each. The results of the study explained that the pelleting technique had no effect on germination, root length, coleoptile length, wet safe weight, dry safe weight, seed weight and had a significant effect on the emergence of plumules with the best treatment obtained in the soil. CMC + humic acid and seed pellet weight. stated that seed pellets can change the weight, size and shape of seeds so as to facilitate planting. The conclusion of this study is that shallot seed pelleting can be applied to shallot cultivation because it does not inhibit the growth and development of shallots and can facilitate the planting of shallot seeds. Key words:  Shallot, seed, pelleting, TSS

Abstract

Biochar is a carbon-rich solid produced from the pyrolysis of biomass such as wood, manure, and leaves under high temperature and low oxygen conditions which is used for agricultural applications as a soil amendment. This paper reviews the utilization and practical application of biochar. The application of biochar into the soil can improve the physical, chemical and biological properties of the soil, namely increasing porosity, water holding capacity, soil aggregation, increasing pH, cation exchange capacity, soil organic carbon, nutrient retention and availability, and increasing microbial life, meso and soil macrofauna. Aside from being a soil amendment, biochar has a function on issues of global warming, climate change, and the environment, namely its role in carbon sequestration and stabilization, greenhouse gas emissions, and soil pollutant remediation. If biochar is applied properly, namely using the right feedstock materials, method of manufacture, dosage, method of application, and place, it will affect agronomic performance and crop yields. Reduced yields are mostly occured in temperate climates as biochar significantly increases soil pH causing an effect of excessive liming resulting in immobilization of key nutrients such as Mg, Fe, B, and P. Biochar needs to be mixed or applied together with fertilizer ingredients such as chemical fertilizers, bio-fertilizers, compost, and manure. Another effort is to enrich biochar with those materials so that biochar is categorized as a biochar-based fertilizer that has a higher selling price. Key words : Application, biochar, benefit, method, crop yield

Abstract

Weeds are plants whose existence is not expected by farmers because they interfere with cultivated plants. But there are weeds that can produce phenolic compounds such as Clidemia hirta L which can be used as bioherbicides. This study aims to determine the effect of Clidemia hirta L. leaf extract on the germination and growth of Praxelis clematidea weeds. The research was carried out from June 2021 to September 2021 at the Weed Science Laboratory and Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. This study used a completely randomized design (CRD) method with 6 treatments with concentrations of Clidemia hirta L leaf extract, namely 0; 1.5; 3.0; 4.5; 6.0; and 7.5%. Each treatment was repeated 6 times to obtain 72 experimental units. The observed variables are germination, crown height, root length, dry weight, and weed poisoning level. The data obtained were analyzed by analysis of variance and continued with the Least Significant Difference Test (LSD) at the 5% level. The results showed that the germination of Praxelis clematidea weed was significantly inhibited by the treatment of Clidemia hirta L leaf extract with a concentration of 1.5; 3.0; 4.5; 6.0; and 7.5%.
