Abstract Porang (Amorphophallus muelleri Blume) is usually cultivated on the field under the tree as natural shading. Porang can also be grown on a pot containing limited amount of growth media. The present research work was carried to evaluate the minimum amount of growth media required for optimum growth and corm yield. The study used bulbils (10 g/bulbil and 20 g/bulbil) and corm (+ 15 g/corm) sown on growth media of 2.5 kg, 5.0 kg and 7.5 kg/pot as treatments. Each treatment was arranged in completely randomized design and was replicated 3 times. Plant height, plant diameter, shoot dry weight, diameter and thickness of corm and fresh weight of corm were measured to evaluate the influence of the treatments on growth and corm yield of porang. The plant growth of porang measured as plant height, plant diameter, shoot dry weight was improved when the planting materials were planted on bigger size of growth media. Bigger size of bulbil caused better growth of porang on each growth medium. The effect of plant materials and the size of growth media on porang growth was in parallel to its effect on corm yield measured as corm diameter, corm thickness and fresh weight of corm. The result of the present study suggests to use bigger bulbil and bigger size of growth media when planted on polyethylene bag. Corm as planting material was better than bulbil because less size of corm produced similar plant growth and corm yield compared to bigger size of bulbil. Therefore, the use of corm as planting material is more favorable to bulbil.

Abstract Background Orobanche crenata is an obligate root parasite belonging to Orbanchaceae. Broomrape causes great damage to the faba bean. Several attempts were applied for controlling parasitic weeds. So, the aim of this work is to study the application of Trichoderma spp. as well as three rhizobacteria species in comparison to herbicidal effect of Glyphosate (Glialka 48% WSC) for controlling broomrape infesting faba bean (Vicia faba). Materials and methods Three pot experiments were carried out in the greenhouse of the National Research Centre, Dokki, Giza, Egypt during two successive winter seasons. Trichoderma inocula were adjusted to 3.6 × 108 propagules/ml and the bacterium inocula were adjusted at 107–109 colony-forming unit (CFU)/ml. All treatments were applied, before 1 week of sowing, at rate of 50 ml per pot in experiments I and II, while 100 ml per pot in experiment III. Results Trichoderma spp. (T. harzianum, T. viride and T. vierns) as well as three rhizobacteria species (Pseudomonas fluorescens, Bacillus subtilis and Bacillus pumilus) enhanced the growth parameters in faba bean plants, i.e. shoot length, shoot fresh weight, shoot dry weight and leaf number in the first experiment when applied without O. crenata infection. In the second experiment, all bio-control could protect plants against O. crenata infection, where it had better juvenile number reduction, than glyphosate after 2 months of application. Both B. subtilis and B. pumilus had the highest reduction to juvenile fresh weight, while their effect was equal to herbicide for juvenile dry weight, respectively. The bio-control agents had high effects until the 4th month, but it was less than that of the herbicide. In experiment III, the bio-control agents could highly reduce the juvenile parameters after 2 months, as well as juvenile fresh weight and juvenile dry weight after 4 months, than the herbicide, respectively. The bio-control agents were effective until 6 months, but less than the herbicide effect. All bio-control treatments highly increased the plant growth parameters, than the herbicide. Conclusion The application of Trichoderma spp. as well as rhizobacteria species could play an important role in controlling broomrape in faba bean as a natural bioherbicide.

The paitan plant contains allelopathic compounds for other plants so that the utilize of paitan plant as a source of liquid organic fertilizer (LOF) has not been widely applied. This research aimed to study the interaction between LOF dosage and appropriate application method of LOF to increase the growth of kailan plants. The research conducted at experimental garden of UIN Bandung from June-August 2016. The experimental design was a completely randomized design with two factors and replicated four times. The first factor was application methods (A), i.e. a1=direct application to the soil, and a2= spraying. The second factor was LOF dosage (T), i.e. t0: 0 ml plant-1, t1: 20 ml plant-1, t2: 40 ml plant-1, t3: 60 ml plant-1, t4: 80 ml plant-1. The growth parameters observed i.e. plant height (14, 21, 28, 35 and 42 Day after Transplanting (DAT)), leaf area 42 DAT, plant dry weight 42 DAT, and plant fresh weight 42 DAT. The data then analyzed with analysis of variance at a significant level of 5%. If the analysis of variance was significant, the Duncan multiple range test was used at α=5%. The research results showed there was no interaction between method of application with a various dosage of paitan LOF to all of the growth parameters. The application paitan LOF showed similar growth in terms of plant height, leaf area, plant dry, and plant fresh weight. The application method of paitan LOF direct to the soil or spraying to leaves can not increase kailan plant growth.

ABSTRACT: Cultivated and weedy rice biotypes exhibit morphophysiological variations under low light, affecting competition between plants. The aim of this study was to assess relative competitiveness between cultivated and weedy rice under full and low light. Three experiments were conducted in a greenhouse, using a completely randomized design with four repetitions. The treatments in the experiment I were arranged in additive series while in the experiments II and III treatments were arranged in replacement series. Experiments II and III were carried out concomitantly to assess coexistence between the rice cultivar and weedy rice. The treatments consisted of different plants proportions: 100:0 (cultivated rice monoculture), 75:25, 50:50, 25:75 and 0:100 (weedy rice monoculture), keeping the total plant population obtained in experiment I (240 plants m-2) constant. Experiment II was conducted with full solar radiation and III under 50% light. The variables analyzed were shoot dry weight and plant height, 35 days after emergence (DAE). Competition among plants was evaluated via graphs and by interpreting competition indices. Concerning shoot dry weight, mutual losses were recorded between competitors, whereas equal competition for resources was observed for plant height. Weedy rice was more competitive than cultivated rice regardless of the light environment assessed, indicating the need for integrated methods to control this weed.

A one-time application of fish emulsion 2 days before the application of plant growth regulators (PGR) showed an overriding effect on the growth of pansies. Blue/blotch shades of `Medallion' pansies were placed on a constant feed program of 100 ppm Peat Lite 20N–10P–20K, with half of the pansies receiving an additional one-time supplement of fish emulsion. PGRs and rates included B-Nine, 0.5% (used as the control); uniconazole, 2 and 4 ppm; and paclobutrazol, 16 and 25 ppm. Parameters taken included plant height, top fresh weight, top dry weight, days to anthesis, and visual appearance. Significant differences were noted in the plants receiving the supplement for plant dry weight, plant height, and visual appearance. Plants receiving fish emulsion grew taller and denser than those on constant feed alone despite the effects of the PGRs.

Pertumbuhan bibit kopi Liberika hasil grafting dengan bibit kopi Robusta terbaik pada berbagai panjang entres diperoleh pada kopi Robusta bermikoriza.” The main goal of coffee grafting is to create a crop with the best characteristic of two coffee varieties in one plant. Robusta coffee is used as the rootstock, which is more resistant to constraints and unfavorable conditions in the peatland. The effort to increase rootstock resistance is inoculated by mycorrhizae and grafted with Liberica coffee as the scion. This study aimed to obtain the best scion length in order to increase the growth of Liberica coffee with Robusta coffee as the inoculated rootstock. The experiment used factorial completely randomized design with the first factor was mycorrhizae inoculation (without inoculation and inoculation of Glomus sp-1a and Glomus sp-3c combination) and the second factor was  the length of scion (10, 15, 20 and 25 cm). The variables observed were the percentage of success grafted plants, shoot break time, growth (plant height, number of leave, number of shoots, and shoot dry weight) and mycorrhizae infection. The results showed that the plant inoculated by mycorrhizae and scion lenght of 15 cm gave the best percentage of the success graft, shoot break time, and growth of scion. While, the root stock without inoculation showed the best result with the scion length 25 cm. The best growth of grafted plant was obtained in all scion length with mycorrhizae inoculation.

Open mining activities have caused soil damage, water pollution, air pollution, and damage to vegetation. Limestone post mining is a critical area that must be rehabilitated to be productive again. This problems can be fixed by doing land reclamation activities which mandated in the Mining Law Number 4, 2009. The success of land reclamation is largely determined by the choice of plant species and the provision of appropriate soil enhancers (ameliorant). This study was aimed to analyze the growth response of sengon plants on giving ameliorant in mixed limestone post mining soil. This study was designed in completely randomized design for 7 treatments and 3 replications used combination of ameliorant: P0 (without ameliorant); P1 (AH 4 kg ha-1); P2 (BFA 350 kg ha-1); P3 (FMA 500 spores plant-1); P4 (the combination of AH and FMA); P5 (the combination of BFA and FMA); and P6 (the combination of AH, BFA, and FMA). Data were processed by analysis of variance at the 0,05 significance level followed by the Least Significant Difference test. The results showed that the best growth response of sengon on giving ameliorant in mixed limestone post mining soil was P1 treatment (humic acid material) which significantly increased root length, root volume, root fresh weight, shoot fresh weight, root dry weight, and shoot dry weight in sengon plants. The addition of ameliorant can be recommended to improve the quality of revegetation plants

The effects of two mycorrhizal species (Glomus versiforme and Glomus intraradix) and a control on the growth of green pepper, Capsicum annuum, and lettuce, Lactuca sativa, seedlings have been evaluated using four types of growing media (Peatwool, Fafard bulk mix. Cornell mix and a compost based mix) and two types of containers, Cell Packs (125 cc volume) and Pro-Trays (65 cc volume) for green pepper and Cell Packs (125 cc volume) and Plug Flats (33 cc volume) for lettuce. The experiments were split plot randomized Complete block design with 6 blocks (lettuce) and 4 blocks (pepper). Seeds were sown directly into the containers of mycorrhizal inoculated media. All treatments received the same fertilizer regime. Cell volume had no significant effects on green pepper fresh weight, dry weight, stem diameter, leaf area or leaf number but the lettuce Cell Pack plants had significantly higher fresh and dry weights, more leaves and higher leaf area. The Fafard Bulk and the Compost mix gave significantly higher fresh and dry weights than did the other two media for both green pepper and lettuce. Mycorrhizal species did not influence plant growth with the exception of leaf area in green peppers and shoot dry weight in lettuce.

Weed-competitive cultivars are desired in the wake of growing popularity of organic farming, environmental pollution and evolution of herbicide resistance in weeds. This research work evaluated the weed competitive ability of three forage maize cultivars (ADA-523, AGA and SASA-5) against the noxious weed barnyardgrass (Echinochloa crus-galli (L.) P.Beauv.). The study was conducted in spring 2018 and repeated in summer 2018. Results of this study showed that maize-barnyardgrass competition significantly decreased the growth of forage maize plants. For instance, barnyardgrass decreased the maize plant height by 11.9-16.9%, leaf length by 13.3-20.2%, leaf width by 20.2-27.4%, and number of leaves by 14.3-25.0%. Fresh and dry weights of maize plants were also significantly decreased as a result of weed-crop competition. Barnyardgrass decreased the shoot fresh weight (30.7-60.6%), shoot dry weight (33.3-52.2%), leaf fresh weight (33.4-56.5%) and leaf dry weight (31.9-50.0%) of the maize plants. An interactive effect of weed × maize cultivars was found non-significant. Forage maize cultivars also varied occasionally for their traits. Nevertheless, ADA-523 had a higher plant height, leaf length, leaf width, leaf fresh weight and leaf dry weight than the cultivars AGA and SASA-5. On the other hand, the cultivar SASA-5 had a higher shoot fresh weight, shoot dry weight and root fresh weight than the other cultivars in the study. This research work concluded that the forage maize cultivars in the study did not vary for the weed-competitive ability. Further, barnyardgrass-maize competition could decrease the growth and development of the maize cultivars.
