The effect of Triplochiton scleroxylon (wawa) aqueousextracts were tested on the seeds of tomato (Lycopersicumesculentum), pepper (Capsicum annuum ) and garden egg (Solanummelongena ) in the pathology laboratory of the Forestry Research Institute of Ghana (FORIG). Aqueous extracts of T. scleroxylon leaves (L) and roots (R) were prepared at different concentrations of 2%, 4%, 6%, and 8% and applied to the seeds. The effects of these treatments were assessed in a Completely Randomized Design (CRD) with 4 replications. The findings showed that all the vegetable crops were affected by the different concentrations of the leaf and roots aqueous extracts (P<0.05). Tukey-Kramer multiple comparison indicated that the inhibitory effect was positively correlated with concentration of the extracts. The higher extract concentrations (6%-8%) had stronger inhibitory effect whereas; in some cases the lower concentration (2%-4%) showed stimulatory effect during germination. The radicles were more susceptible to the effect of the extracts than the plumules. The germination of L.esculentum was highly inhibited in growth by 51.4% in both the leaf and root extracts. Similarly, C.annuum recorded the highest inhibitory effect on radicle length by 72.5% in the leaf extract whilst, the highest inhibitory effects in plumule was 44%. The overall results point to an allelopathic inhibitory effect of T. scleroxylon on the three vegetable crops.

Saffron intercropping with other plants needs to preliminary investigations about the possible negative interactions between saffron and associated crop. In this study, allelopathic effects of saffron leaf and corm extracts on germination and seedling growth indices of alfalfa (Medicago sativa), arugula (Eruca sativa) and rapeseed (Brassica napus) was investigated in six separate experiments based on completely randomized design. Experimental treatments were consisted of different levels of saffron leaf and corm extracts including 0, 0.75, 1.5, 3 and 6%. The maximum germination percentage of all selected crops was obtained at control treatment (on average 92%) and then decreased with increasing extracts concentration. So that, the germination percentage of arugula, canola and alfalfa in highest concentration of extracts were 18, 10 and 8% for leaf extract and 72, 68 and 93% for corm extract, respectively. The relatively similar trend was observed about germination rate, root and plumule lengths and dry weights. Therefore, the inhibitory effect of saffron leaf extract was more than corm extract on initial growth indices of studied plants. The lowest inhibitory effect of saffron leaf extract and even relatively high stimulatory effect of corm extract were obtained on alfalfa initial growth criteria. Considering the differences in allelochemicals mode of action and concentrations in laboratory bioassays with natural condition, it is necessary to investigate the effects of saffron residues on growth of selected associated crops in greenhouse and field scales for the final decision.

ABSTRACT: Improper management of weeds is one of the causes of low bean yield, as it is very susceptible to interference due to their slow initial growth. This study aimed to evaluate the influence of dayflower on grain yield and nutrient accumulation of bean cultivars. The experiment was carried out in a screened house, in 5 L pots, in a 2 x 4 factorial scheme. Factor 1 corresponded to the presence or absence of weeds, and factor 2 bean cultivars: BRS Pontal, BRS Agreste, BRS Ametista and BRS Estilo. The experiment was arranged in a completely randomized design with five replications. The coexistence of bean and weed was maintained throughout the crop cycle. Chlorophyll content, number of pods per plant, number of grains per plant, nutrients contents (N - nitrogen, P - phosphorus, K - potassium, Ca - calcium, Mg - magnesium, Mn - manganese, Fe - iron and Zn - zinc) in grains were evaluated. Competition with weeds negatively influenced chlorophyll content, number of pods, yield and N content in grains. The interaction was significant to P, Mg and Fe contents in grains, demonstrating that competition with weeds may impair allocation of these nutrients, resulting in grains of inferior nutritional quality. The cultivar BRS Agreste was more efficient to accumulate P and Mg in grains in competition with dayflower.

<h1>Spodoptera litura F. is one of the important pests in Horticulture commodities which can cause damage 80% and up to 100%. Karamunting (Melastome malabathricum) is a wild plant that grows in Tarakan City. This plant is known to contain secondary metabolites which are thought to have the potential to control pests. This study aims to determine the potential of Karamunting extract as a botanical insecticide material to control armyworms. This study uses a completely randomized design (CRD) method with 1 treatment factor, namely the concentration of Karamunting leaf extract. Potential extracts as botanical insecticides were tested by dye method using 4 concentrations, namely 0 (control); 500; 1000; 2000; 4000; and 8000 ppm. The results showed that Karamunting leaf extract was able to control armyworm pests. Giving extracts of 8000 ppm (P5) in feed caused the highest decrease in eating activity up to 41,2%, larval mortality up to 85%, and the highest mortality rate after 7 days of observation. Decreased feeding activity and larval mortality were thought to be influenced by the presence of phenol compounds, fatty acids, terpenoids, sterols and alkaloids identified in the extract. Thus, Karamunting leaf extract has the potential to be developed as an active ingredient in botanical insecticides to control armyworm.<strong></strong></h1>

The application of Trichoderma fungus can be used to obtain seedlings of higher quality for plantations. The objective of this study was to evaluate the effects of Trichoderma isolates on the germination and initial growth of açaí seedlings. Two trials were set up. In the laboratory, the seeds were inoculated in suspensions prepared with each of the isolates for 24 h, and they were arranged in trays containing filter paper in a completely randomized design with five replicates containing 50 seeds each. For the control, the seeds were submerged only in water. Part of the seedlings resulting from seeds treated and not treated with Trichoderma were transferred to bags containing forest soil and were submitted to seven modes of application of Trichoderma and kept in a nursery. The speed of germination and hypocotyl were not influenced by the biological treatment. The application of the different Trichoderma isolates positively influenced the height, collar diameter, number of leaves, root size, leaf area and root, and aerial part dry mass of the açaí seedlings. The application of the Trichoderma isolate TAM01 on the preplanting substrate and biweekly applications on the postplanting substrate was the combination that most positively influenced the development of açai seedlings.

Red calliandra (Calliandra calothyrsus Meissn.) leaf have the potential as phytoestrogens. In this study, adult female ovariectomized rats (as a model of menopause women) were given calliandra leaf extract containing estrogenic flavonoids. This study was an experimental design with a Completely Randomized Design (CRD). Forty-five ovariectomized female rats were divided into five groups i.e. untreated control (K), and the treatment group given 80% of C. calothyrsus ethanolic leaves extract doses 25 mg/ kg bw (P1), 50 mg/ kg bw (P2), 75 mg/ kg bw (P3) and 100 mg/ kg bw (P4). The test suspension was given once a day at 24-hour intervals by gavage as much as 0.5 ml/rat/day for two months. At the end of the treatments, blood was collected for blood biochemical tests including hemoglobin levels, hematocrit values, blood glucose and proteins levels. The results showed that C. calothyrsus leaf extract did not negatively affect the health status of the animals through blood biochemical parameters, i.e. hemoglobin levels, hematocrit values, and glucose and protein levels of ovariectomized female rats.

Screen house experiments were carried out to examine the effects of aqueous leaf extracts of Tithonia diversifolia (Ti) and Vernonia amygdalina (Ve), as well as NPK fertilizer (15-15-15) on the germination, growth and development of maize. Fresh leaves were collected, washed with tap water, chopped and pounded, soaked in distilled water and filtered. The two filtrates were used to prepare extracts at 50 and 100% w/v. Four maize seeds were placed in Petri dishes laid out in a completely randomized design with five replicates. In every Petri dish 10 ml of extract per treatment was added. A control experiment with distilled water was also set up. Also, in a completely randomized design with four replicates, 4-week-old potted maize plants were treated with 500 ml of each extract as well as with 1.52 g of NPK fertilizer. The results showed that the germination percentage of the seeds followed the order Ti50 - Control - Ve50. The seeds treated with aqueous extracts of T. diversifolia and V. amygdalina at 100% w/v produced lower but equal germination percentage. The seedling radicle growth was significantly inhibited by the aqueous extracts of Ti100, Ve50 and Ve100 (p?0.05). The inhibition was dose-dependent and more pronounced in seeds treated with extracts of V. amygdalina. The aqueous extract of T. diversifolia (50% w/v) and control influenced radicle growth substantially. All the extracts inhibited the plumule development compared to the control. On the other hand, growth, development and yield were not significantly affected by the plant extracts.
