Abstract

This research was conducted to observe the effect of age’s differenceseedling to growth and yield of six Paddy varieties at peatland. Theexperiment was arranged in factorial Randomized Block Design withthree replications. The first factors were time of age seedling (3, 4, 5, 6weeks), and the second factors were six cultivars of paddy (Cisokan, IR-42, IR-64, Batanghari, and two local cultivars, there are Ceko danKuatik). The data were analyzed with ANOVA and DMRT. The resultsshowed that, there no interaction effect between seedling age andcultivars. Furthermore, there is no simple effect, on relative growth rate(RGR) and maximum advantity shoots, but signifianly influence toheight of plant and Net Assimilation Rate (NAR), rate of initation andyield. Cisokan and Batanghari cultivars were showed the highest yieldKey words : Paddy, varieties, NAR, PGR

Abstract

Anthracnose caused by Colletotrichum actuate is one of devastated disease ofpepper in Indonesia that has great impact on yield loss. Most of farmers usefungicides as controller for this disease. Application of biocontrol agentscould be one ways to control anthracnose. Beneficial microorganism such asyeast is able to be promising biocontrol agents of some pathogens, includingColletotrichum. The aim of this research was to isolate yeast from fruit andbranch as biocontrol agents for pepper anthracnose. The research results 9isolates of yeasts that were further tested against anthracnose. Isolates ofyeasts were identified as Cryptococcus terreus, C. abides var. aerius IPB 1,and C. abides var. aerius IPB 2, Candida Edam. Other isolates coded asCBN, CBM, CBK, CBF, and CBR were not identified yet. Five of potentialyeasts, Cryptococcus terreus, C. albidus var aerius IPB 1, C. albidus varaerius IPB 2, Candida edax, and unidentified yeast CBN showed directantagonist mechanism. Among of potential yeasts isolated, CBN showedability to reduce incidence of disease up to of 87.50%.Key word: Pepper, antrachnose, C. acutatum, yeast

Abstract

Endophityc fungi have been successfully isolated from Oryza sativa atLaboratory of Plant Disease, Agriculture Faculty University of Jambi. Theaim of this research was to get endophityc fungi from Oryza sativa. Therewere three (3) candidates of endophityc fungi that have been successfullyisolated. Pathogenosity test which was done showed that all of fungi wereendophityc fungi. Those fungi were identified as endophityc fungi due to theseed of paddy could growth normally in pure culture of endophityc fungi. Thethree of isolated endophityc fungi were identified as Hifa steril 1, Hifa steril 2,and Fusarium sp.Keyword: endophityc fungi, Oryza sativa

Abstract

One way to improve the productivity of soybean grown as an intercropping plant in the standing area is to develop soybean varieties that are tolerant to shade. This experiment aimed to discover the physiological characteristics in soybean varieties that are tolerant to shade.The results showed that the significant physiological characteristics that determine the level of the soybean tolerance to shade are nitrogen and protein contents.The increasing of nitrogen and protein contents was higher in the tolerant varieties than those of sensitive varieties. Shade treatments affected seed weight. The soybean yield on the 50% shade decreased by 23.11% in the tolerant varieties, and about 27.63% decreased in the sensitive varieties. The yield decrease was lower in tolerant varieties compared to the sensitive varieties. This result was supported by the lower reduction in empty pods.Mechanism of tolerance to shade on soybean plant is characterized by the increase of nitrogen and protein contents. In addition, higher yields on tolerant varieties supported by high pods contain and low empty pods.Key words: Soybean, nitrogen and protein contents.

Abstract

The aim of this research was to examine the effect of different material and dosages of liquid organic fertilizer on growth and yield of lettuce. The experiment was conducted at Agriculture farm, Jambi University. The laboratory analysis of soil and plant was conducted at Agriculture Laboratory and material of organic fertilizers in BALITRO, Bogor. Research design used factorial, arranged with randomized complete block designed. The treatment are Factor I material of organic compost liquid, control (p0), Imperata cylindrica (p1), Cromolaena odorata (p2) and Leucena lecochepala (p3), and the second factor are dosage, control (d0), 5 ml (d1), 10 ml (d2) and 15 ml (d3). Result showed that there was interaction affect between liquid compost material and dosage on growth parameter, number of leaves, leaf area, plant height, fresh weight dan plant yield. The trend of growth parameter indicated that compost material Cromolaena odorata at dosage 15 ml showed the highest. The same result was achieved at lettuce yield. However, in this research the optimum combination of liquid compost material and dosage was not yet attainable.Key words: Fertilizers, lettuce, cromolaena, leucena, imperata

Abstract

The aim of this study was to obtain the best combination of 2,4-D and BAP in inducing callus from leaf explants durian cv. Selat Jambi. Experiment was arranged in completely randomized design with a growth regulators combination of treatment 2,4-D (1, 2, 3, 4, 5, 6, 7 ppm) and BAP (0,0 ; 0.5 ppm). Each treatment consisted of 10 bottles each culture bottle were planted on explant culture. Explants were cultured on induction medium for 2 month. The parameter time of calli initiation were observed every day. Meanwhile the percentage of explant forming callus, callus structure and color of callus was observed at the end of the study. The results showed that, granting some combination of growth regulators 2,4-D and BAP are given to the culture medium was able to stimulate the formation of callus on leaf explants young durian CV. Selat Jambi. Time of the fastest callus initiation (8 days after cultur) was obtained on medium 4 ppm 2,4-D + 0.5 ppm BAP. In contrast, the highest percentage of explants forming callus was obtained on treatment of 5 ppm 2,4-D (30%).Key words: Exsplants, Durio zibethinus, callus, BAP, 2,4-D

Abstract

This study was aimed to determine the response of peanut to some extent water, the level of water content and water needs best influence on the growth and yield of peanut crops. Experiment was arranged in a completely randomized design (CRD) with one factor, namely the provision of water that consists of five levels, namely the provision of water to the conditions of 25%, 50%, 75%, 100% and 125% field capacity. The variables measured were plant height, days to flowering, canopy dry weight, number of pods containing the number of empty pods, 100 seed weight and seed yield crop.The results showed that the water level significantly affected plant height, days to flowering, canopy dry weight, number of pods containing the number of empty pods, 100 seed weight and seed yield crop. The level of water to the 100% field capacity conditions provides growth and yield of groundnut crop was best.Key words : Peanuts, water content, water level

Abstract

The objectives of this research are to analysis the growth and yield of Lettuce (Lactuca sativa L) at different type of organic liquid fertilizers. The experiment has conducted at Agriculture Faculty Research Farm, Jambi University. Six treatments were arranged in Randomized Completed Block Design. The treatments are kinds of liquid organic fertilizers, they are P0 (none of liquid organic fertilizers), P1 (Golden Harvest liquid organic fertilizers), P2 (NASA liquid organic fertilizers), P3 (Compost Tea liquid organic fertilizers), P4 (Nutrisi Saputra liquid organic fertilizers), P5 (Bio Subur liquid organic fertilizers), and P6 (Alam Natural I liquid organic fertilizers). The result shows that there is significant effect of liquid organic fertilizers to every parameter of growth analysis: average leaf area index, average net assimilation rate and average plant growth rate. The trend of growth parameter indicated that Golden Harvest always achieved the highest. The highest lettuce yield was achieved at Golden Harvest liquid organic fertilizers, but there are no significant differences effect between Golden Harvest and Bio Subur.Key words : Lettuce, growth, yield, liquid
