Abstract

[IMPROVEMENT OF PEANUT GROWTH AND PRODUCTIVITY IN DRY LAND THROUGH THE APPLICATION OF DOLOMITE AND NPK FERTILIZERS]. Dry land is commonly characterized by low pH and nutrient availability for peanut growth. Therefore, application of dolomite and NPK fertilizer might correct its characteristics. This study aimed to determine the appropriate dose of dolomite and NPK fertilizers to increase growth and productivity of peanut in dry land. This study was carried out from November 2019 to February 2020 at the Meteorological, Climatological, and Geophysical Agency, Indrapuri Experimental Garden, Aceh Besar, Aceh and used a randomized block design (RBD) with two factors and three replications. The first factor was three dosages of dolomite (i.e., 0, 250, and 500 kg/ha) and the second factor was three levels of NPK fertilizers (i.e., 0 kg/ha Urea+ 0 kg/ha SP36+ 0 kg/ha KCl), 25 kg/ha Urea + 50 kg/ha SP36 + 50 kg/ha KCl, and 50 kg/ha Urea + 100 kg/ha SP36 + 100 kg/ha KCl). The results showed that application of dolomite or NPK fertilizers had a significant effect on peanut yield components. Application of dolomite at 500 kg/ha or NPK fertilizers at 50 kg/ha Urea + 100 kg/ha SP36 + 100 kg/ha KCl increased peanut productivity by 10% and 9.23%, respectively compared to the control.

Abstract

[BIO-COMPOSTING OF SOLID OIL PALM WASTE WITH DIFFERENT DECOMPOSERS AND PHYSICOCHEMICAL CRITERIA FOR COMPOST QUALITY ASSESSMENT] The quantity of produced wastes by oil palm industry is increasing and may lead to significant environmental concerns and the use of these wastes as compost is considered to overcome their negative impacts. However, very few studies have been conducted to develop an effective composting process of the biomass waste using different decomposers. Therefore, the objective of this study was to assess the different physicochemical and biological quality of compost produced by bio-composting of solid oil palm waste with three different commercial decomposers. This study was conducted from September 2021 to November 2021 at the Compost House, Faculty of Agriculture, University of Lambung Mangkurat. A certain period of bio-decomposition process was employed by using commercial bio-decomposers. Physicochemical and biological analyses of the composted solid waste were conducted after decomposer application. The experiment consisted of four treatments (i.e., solid oil palm waste + chicken manure, solid oil palm waste + chicken manure + EM4, solid oil palm waste + chicken manure + M21, and solid oil palm waste + chicken manure + Tangguh) and they were arranged in completely randomized design with three replicates. Results showed that quality of all compost met the SNI 400 standard except for pH, organic-C, and C/N ratio for the treatment without bio-decomposer,  pH and C/N ratio for the treatment EM4 bio-decomposer, water content, pH, organic-C, and C/N ratio for M21 bio-decomposer, and pH, organic-C, and C/N ratio for the treatment with Tangguh bio-decomposer, respectively. The maximum germination test obtained was recorded at 70%, 80%, 94%, and 86% in compost media without bio-decomposer, with EM4, 94% with M21, and with Tangguh, respectively. The maximum number of microbes were recorded at 3.2 x 106 µg/g, 2.9 x 105 µg/g, 1.3 x 106 µg/g, and 8.0 x 105 µg/g for compost without bio-decomposer, with EM4, with M21, and with Tangguh bio-decomposer, respectively.

Abstract

[RESPONSE OF IN VITRO SHOOT INDUCTION ON VANILLA PLANTS (Vanilla planifolia) TO THE CONCENTRATION OF BAP AND 2,4-D]. The seeds of V. planifolia A. are plantation product that can be used as food scent and industrial ingredient. On its progression, vanilla farmers propagate by cuttings. The process of vanilla cutting has ben anobstacle in terms of pathogen attack and slow grow, and cuttings propagation is considered unable to meet the demand for seedlings. Tissue culture is a technology that can overcome problems in the vanilla propagation process. The research took place from January to June 2022 at the University of Jember, Bondowoso Campus.  The research  aims to determine the response of shoot induction to the addition of hormones. The completely randomized design (CRD)  was used with 2 factors,the BAP at concentration of 0 , 0.5  and 1 ppm combined with 2,4-D at concentrations of 0.5 , 1 and 1.5 ppm. The data were analyzed using ANOVA with a significant level of 5% and continued with the DMRT test with a significant level of 5%. The results showed that there was an interaction between concentration BAP and 2,4-D in vitro vanilla culture. The treatment without hormones showed a longer shoot formation and the combination of 2,4-D with a higher concentration caused an inhibition in shoot elongation. The combination treatment of 0.5 ppm BAP and 0.5 ppm 2,4-D also 1 ppm BAP and 0.5 ppm 2,4-D had the best response indicated by the highest shoot length and faster shoot formation.

Abstract

[THE EFFECT OF MICRO-COMPOUND FERTILIZER AND HUMIC ACID ON AVAILABILITY OF P AND  UPLAND RICE YIELD IN COASTAL LAND] Indonesia’s coastal areas are potential  for the  agriculture. However, coastal areas have poor physical, chemical and biological soil properties that unfavorable  to the growth and yield of plants. Upland rice is a food crop that can be developed on coastal land using  humic acid technology and micro-compound fertilizers. This study aims to determinate the effect  of micro-compound fertilizers and humic acid on phosphor availability and upland rice yields on coastal land. This research was conducted from August to December 2021 in Beringin Raya Sub-District Muara Bangka Hulu, Bengkulu City. Soil and plant analysis was carried out in the Soil Science Laboratory, Faculty of Agriculture, Bengkulu University. This research was organized in  Randomized Completely Block Design (RCBD) with 2 factors. The first factor is micro-compound fertilizer which consists of 3 levels, namely 0, 70 and 140 g/ha and the second factor is humic acid which consists of 2 levels, namely 0  and 8 L/ha. Each treatment combination was reploicated 4 times. The results showed that there was no interaction between humic acid and micronutrient fertilizer on the observed variables. The application of humic acid at 8 L/ha  increased phosphor available by 27.55%, the root colonization by 20.65%, the population of microorganisms by 14.77%, the number of productive tillers of 15.72% and the weight of the pithy grain per plant by 31.50% as compared to control. Also, the application of micronutrient fertilizer at 140 g/ha increased the  weight of 1000 seeds, the number of productive tillers, the pithy grains by 7.22, 18.53, and 27.77% respectively as compared control. It is recommended that the upland rice variety can cultivate in coastal land with the application of 140 g/ha micronutrient fertilizer combined with 8 L/ha of humic acid.

Abstract

[PHYSIOLOGICAL RESPONSES AND YIELDS OF FOUR LOCAL GOGO RICE CULTIVARS OF CENTRAL SULAWESI TO DROUGHT STRESS]. Rice is the most important staple food for Indonesians and can be grown in dry land agroecosystems as an upland rice. The research was conducted to study the physiological mechanisms related to drought resistant schemes on four local upland rice cultivars of Central Sulawesi. Field research was carried out using factorial Completely Randomized Block Design (CRBD) with two factors and three blocks as replication. The first factor was four cultivars of upland rice, i.e., Habo, Hiwanggu, Sunggul, and Lambara; while watering intervals of once in one, two, four and eight days was considered as second factor. The observed variables of this experiment were soil moisture, relative water content of leaf, stomatal conductance, concentration of leaf carbon dioxide, transpiration rate, photosynthesis rate, and yield of grain per grove. The collected data were analyzed with regression using independent variables of soil moisture and dependent variables of relative water content on leaf, stomatal conductance, concentration of carbon dioxide on leaf, transpiration rate, photosynthesis rate and yield of grain per grove. The relationship among observed variables was determined using correlation analysis. The results showed that drought resistant upland rice cultivars (Habo and Sunggul) required less optimum soil moisture than those of non-drought resistant cultivars (Hiwanggu and Lambara) to maximize relative water content, stomatal conductance, carbon dioxide, transpiration rate and photosynthesis rate. Soil moisture contributions to maximum yield of grain per grove on Habo, Sunggul, Hiwanggu and Lambara cultivars were 23.41%, 23.00%, 27.14% and 26.67%, respectively.

Abstract

[CHANGES IN SOIL CHEMICAL PROPERTIES AND MUNG BEAN (Vigna radiata L.) YIELD IN INCEPTISOLS, NORTH MORAMO AS AFFECTED BY APPLICATION OF SAGO WASTE COMPOST]. Inceptisols are one of the most widespread soil types in Southeast Sulawesi with an acreage of ​​around 2,280,567 ha (62.07%) and potential for agriculture development. The primary drawback of Inceptisols developed for cultivating mung bean includes a highly acid soil reaction with low soil pH. The polybag experiment was conducted with the objective to determine changes in the chemical properties of the soil after being amended with sago waste compost and its effects on mung bean yield. The research was conducted at the Experimental Garden of the Faculty of Agriculture, Halu Oleo University. This study used a randomized block design consisting of five levels of sago pulp compost (i.e., 0, 100, 200, 300, and 400 g/polybag) with three replications. The results showed that the application of 400 g/polybag of sago pulp compost increased soil pH and organic C by 5.02 and 2.23%, respectively. Increases were also observed in total-N (0.24%), available-P (19.85 ppm), available-K (0.24 me/100g), and CEC (11.99 me/100g). The application of 300 g/polybag of sago pulp compost resulted in the highest number of pods (11.33 pods) and the weight of 100 green bean seeds (9.39 g).

Sorghum is one of the allelopathy-producing plants and the allelochemical content of sorghum plant parts varies. Therefore, each ratoon organs of sorghum has the potential as a bioherbicide. The aim of this study was to determine the potential of water extracts of six months-fermented ratoon sorghum organs cultivated in swamp lands as bioherbicides. The research was conducted in swamp land in Kandang Limun and Bentiring Permai Bengkulu City, Bengkulu Province from November 2020 to May 2021 and continued until October 2022 for bioassay experiment. The experimental design was a Completely Randomized Design (CRD) with a single factor with four replications. The treatment was fermented ratoon sorghum water extract for six months consisting of four levels (i.e., control, leaf, stem and root). Twenty five of mung bean seeds Vima 1 variety  was planted in a petri dish containing 10 mL of fermented ratoon organs and incubated for three days. The results showed that water extract of fermented ratoon plants was able to inhibit sorghum seed germination. Water extracts of fermented sorghum stems and roots was more potential as a source of bioherbicides than those of sorghum leaves or controls. Therefore, it is recommended to use the ratoon sorghum roots or stems for bioherbicide.

[GROWTH AND HARVESTING FREQUENCY OF RED CHILI PLANTS WITH THE APPLICATION OF  NPK FERTILIZERS CULTIVATED ON SUB-OPTIMAL LAND IN FLOATING CULTURE SYSTEM]. The low productivity of red chili in South Sumatra is mostly due to its cultivation was conducted in sub-optimal land that is less favorable for producing vegetable crops. This study aimed to evaluate growth and yield of red chili plants under suboptimal conditions using various doses of NPK fertilizer. The experiment was carried out from June to October 2022, at the water reservoir and experimental field (as a comparison) at the Faculty of Agriculture Universitas Sriwijaya, Indralaya, South Sumatra with an altitude of 10 m above sea level. Both experiments were arranged in a randomized block design with three replications and one factor in the group, namely NPK fertilizer doses (0, 5, 10, and 15 g/polybag). For the experiment in the water reservoir, each treatment was arranged randomly in a 200 cm x 100 cm bamboo raft (for each group). The results showed that the application of NPK fertilizer in floating cultivation did not increase plant height, number of leaves, shoot diameter, and harvesting frequency of red chili. It was concluded that the application of NPK fertilizer in floating cultivation did not increase growth and harvesting frequency of red chili.
