Abstract

The high Aluminum content in Ultisol soil is one of the main problems in maize cultivation starting from the germination phase to plant growth. Priming treatment on seeds is believed to be able to improve germination in a less favorable environment. The study was conducted to determine the effect of priming on the germination of corn seeds germinated in acid media containing aluminum. The study was arranged in a Completely Randomized Design (CRD) which was repeated four times. There were 8 treatments in this study, namely control/without priming, water priming, KNO3 0.1%, and 0.5, PEG-6000 5% and 10%, GA3 50 ppm and 100 ppm. The data were analyzed for variance and continued with a 5% LSD test using the R Studio statistic program. The results showed that 50 ppm GA3 priming was the best treatment for increasing corn seed vigor based on the variables of time of radicle emergence, time of emergence of plumules, growth speed, growth synchronously, vigor index, root length, coleoptile length, wet weight of normal sprouts, and dry weight of normal sprouts. Keywords:priming, corn, germination

Abstract

Bean (Phaseolus vulgaris L.) is generally cultivated in monoculture (sole cropping) by farmers in the highlands as main crops. Increasing land use efficiency (LUE) by inter-cropping sorghum on bean requires certain cultivation techniques so as not reducing the production of seeds or fresh fruit bean. This experiment aimed at determine 1) the yields of seeds and fresh pods harvested from the bean-sorghum intercropping compared to those from the sole cropping and 2) the LUE of the bean-sorghum intercropping.  The research, which was conducted during April-September 2021 in Sekincau District, West Lampung Regency, Lampung Province, Indonesia used dwarf beans Balitsa-2 variety and climbing bean Horti-3 variety, each of which to be intercropped with sorghum of Numbu variety. Five levels of cropping system treatment were arranged in a Completely Randomized Block Design (CRBD) with six groups as six replications. The results showed that there was no difference the seeds yield and fresh pods of bean between those harvested from bean-sorghum intercropping and from monocultures. The seed yield harvested from the dwarf bean-sorghum intercropping was higher, whereas those harvested from the climbing bean-sorghum intercropping was lower, respectively, compared to those harvested from the monoculture. In producing fresh pods, intercroppings of dwarf bean-sorghum and climbing bean-sorghum increased the LUE, respectively. Whereas in producing seeds, the dwarf bean-sorghum intercropping increased the LUE, but the climbing bean-sorghum intercropping decreased the LUE. Key words : bean, fresh pods, intercropping, seeds, sorghum

Abstract

The oil palm plant which has the Latin name Elaeis guineensis Jacq. is one of the main plantation commodities in Indonesia. The growth of weeds on oil palm cultivation land causes competition for growth facilities and affects the growth of oil palm plants (TBM). One of the active ingredients of herbicides used to control weeds in TBM oil palm plantations is metsulfuron methyl herbicide. This study aims to determine the effective dose of 20% metsulfuron methyl herbicide in suppressing weed growth in TBM oil palm plants, to determine changes in the composition of weed species that grow after the application of metsulfuron methyl herbicide, to determine the effect of phytotoxicity on TBM oil palm plants due to herbicide application. This research was conducted in an oil palm plantation in Braja Lebah Village, Braja Selebah District, East Lampung Regency and the Laboratory of Weed Science, Faculty of Agriculture, University of Lampung from August to December 2022. This study used a Randomized Block Design (RAK) with 6 treatments 6 and 4 replications with metsulfuron methyl dose as follows 15; 20; 25; 30g/ha; mechanical weeding and control. The homogeneity of the variance of the data was tested by Barlett's test and the additivity of the data was tested by using the Tukey test and the difference in the mean treatment was tested by the Least Significant Difference (LSD) test at the 5% level. The research results show that; (1) The herbicide methyl metsulfuron 20% at a dose of 15 – 30 g/ha is effective in controlling the growth of total weeds, the dominant weeds Asystasia gangetica and Praxelis climatidea, Boreria alata, Melastoma malabathricum and Richardia brasiliensis up to 12 MSA; (2) Metsulfuron Methyl Herbicide 20% at a dose of 15 – 30 g/ha caused a change in weed composition at 4, 8, and 12 MSA; (3) The application of 20% metsulfuron methyl herbicide at a dose of 15–30 g/ha does not cause poisoning in TBM oil palm plants. Keywords : efficacy, herbicide, oil palm, metsulfuron methyl

Abstract

Identification is an important activity in the management of plant diseases because by knowing the identity of the fungus found in cocoa beans, a strategy can be determined as a first step before controlling the fungus to prevent the spread of the fungus. This research aims to determine the fungi associated with the MCC 01, MCC 02, Sulawesi 1, and THR clones on uncontrol handling and controlled handling cocoa beans and to determine whether uncontrol handling and controlled handling reduce inoculum sources to suppress fungi growth and development. This research was conducted at the Laboratory of Plant Diseases, Faculty of Agriculture, University of Lampung from January 2023 to March 2023. This research was carried out by testing the agar method (agar plate), the media used was potato sucrose agar (PSA). There were four samples of cocoa bean clones, namely MCC 01, MCC 02, Sulawesi 1, and THR from Kuta Dalom Village, Pesawaran Regency, which were grown on 128 plates of PSA media (64 plates using 2% NaOCl and 64 plates without NaOCl) for each clone. Cocoa beans contained 32 cups each uncontrol handling and controlled handling. So there are 128 cups of PSA media. Isolates that have been obtained are then identified 7 days after isolation. Observations in this study were carried out macroscopically and microscopically. Macroscopic observations were carried out to differentiate growing fungi based on the color, shape and size of the colonies. Meanwhile, microscopic observations were made to differentiate growing fungus based on the structure of the fungi body. The results showed that from the uncontrol handling and the controlled handling, three fungi were found, namely Aspergillus flavus, Aspergillus niger, and Rhizoctonia sp. The fungi Aspergillus flavus and Aspergillus niger show that controlled handling can reduce the source of inoculum compared to uncontrol handling. In contrast to the fungi Aspergillus flavus and Aspergillus niger, the fungi Rhizoctonia sp. shows that controlled handling cannot reduce the source of inoculum. Key words:  Aspergillus, bean, cocoa, Rhizoctonia, handling

Abstract

This research tested the effect of soil acidity level on the uptake of macro elements in plant tissue. This research is a type of experimental research that examines the effect of soil acidification levels on the absorption of N, P, and K nutrients in chili plant tissues. This research was conducted on the greenhouse experimental land of the Sambas State Polytechnic, Sambas Regency, West Kalimantan. This activity is carried out from March to October 2022. The research design used a descriptive analysize with three treatments, namely pH = 6 (P1), pH = 7 (P2), and pH = 8 (P3) which were repeated as many as 3 tests. Each treatment consisted of 30 plants planted in a planting medium mixed with soil, burnt husks and animal dung. N, P and K uptake is obtained through the analysis of the covering of stem and leaf tissues. The results showed that the difference in the level of acidification of the growing media did not have a effect on the level of absorption of nitrogen and phosphorus, but level of acidification have effect in potassium absorption in chili plants. Nitrogen content generally decreases in plant tissue samples aged 30 to 45 days after planting, while in plants aged 45 to 50 days after planting, there is enerally an increase in the accumulation of nitrogen in plant tissues. Absorption of phosphorus elements in tissues fluctuates over a period of 30 to 60 days after planting. The phosphorus content found in leaf tissue treatment pH 6 and pH 7 increased from the observation period of 30 to 60 days after planting. Absorption of potassium elements in tissues fluctuates over a period of 30 to 60 days after planting. An increase in Potassium content in stem and leaf tissues occurred in pH 6 treatment samples. Key words : chili, nitrogen, phosphor, potassium, uptake

Abstract

The growth and production of hydroponic water spinach using liquid organic fertilizer and appropriate planting media determines the success of the plant. The aim of this research is to determine the effect of liquid organic fertilizer (LOF) substitution types and planting media on the growth of water spinach (Ipomoea reptans) production. Data collection was carried out in the month 23 Februaty – 30 March 2023 in Pudakpayung village, Banyumanik District, Semarang City. Treatments were arranged using a completely randomized design with 2 factors. Factor 1 is the planting medium in 2 level, M1 = Rockwool dan M2 = Cocopeat, and factor 2 is the substitution of liquid organic fertilizer in 4 levels, N1 = 4 ml/l AB mix, N2 = 3 ml/l AB mix + 2 ml/l POC, N3 = 2 ml/l AB mix + 3 ml/l POC, dan N4 = 4 ml/l POC. Each treatment was carried out in 3 repetitions so that there were 24 experimental units. The parameters observed were plant height, number of leaves, root length, shoot fresh weight, root weight, biomass weight, and leaf color. The data was analyzed for variance and further tested using the honest real difference (BNJ) at the 5% level. The research results showed that the use of LOF of rice waste and papaya fruit could substitute AB mix at a concertation of 2 ml/l AB mix + 3 ml/l LOF or 50%. However, the use of 100% POC cannot replace AB mix in growth and production of water spinach. Keywords : AB mix, cocopeat, liquid fertilizer, rockwool, rice, papaya fruit, waste
