The production of rice has its own requirements like other crops, among these requirements include the various soil reactions like acid-base reaction and redox reaction. The experient was set up to determine the effect of different oxido-reduction status of soil on rice performance. The trial was a 3x2x2 factorial experiment laid out in a completely randomized design (CRD) and replicated three times. The variables included 3 levels of organic matter from poultry source (0t/ha, 6t/ha and 8t/ha), two levels of NPK 15-15-15 fertilizers (0kg/ha and 200kg/ha) and two watering regimes (Field capacity and waterlogged) this gave rise to twelve treatments and four redox status (oxidized, moderately reduced, reduced and highly reduced). Redox potential was measured using a redox potential meter, growth parameters of rice collected included plant height measured with tape rule, number of leaves and number of tillers which were counted. Yield parameters collected includes 1000 grain weight and grain yield measured with a electrical weighing balance. Data collected were subjected to analysis of variance using SPSS version 17 and means were separated using Tukey HSD. Results from the result indicated that rice performance was best under highly reduce and moderately reduced soils.

ABSTRACT: The objective of this paper was to evaluate the effects of different honey concentrations in culture media, in comparison to sucrose medium, for the in vitro development of the epiphytic Encyclea cordigera orchid, in order to improve the process of propagation of the species. The in vitro germination was prepared on a reduced Murashige & Skoog (MS) medium. After 90 days, the seedlings were divided into different treatments, where they remained for another 90 days. Six treatments were set up (30g L-1 of sucrose; 15, 30, 45, and 60g L-1 of honey; and absence of any carbohydrates) in a completely randomized design. Plants were removed from the vials 270 days after the start of the experiment, and the number of roots, length of the largest leaf, length of the longest root, number of leaves, and fresh and dry masses were evaluated. Data concerning the number of leaves and roots were (x+1)1/2 transformed and subjected to an analysis of variance (ANOVA); the means were compared by a Tukey's test set at 5% probability. Medium containing 60g L-1 of honey proved to be superior to the sucrose medium traditionally used, favoring the in vitro growth and development of Encyclea cordigera. This medium can therefore be recommended for the propagation of this species, which is usually cultivated as an ornamental plant.

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.

The preliminary study was carried out to evaluate the growth performance of Jatropha curcas seedlings on different soils at the nursery of the Federal College of Forestry Mechanization Afaka, Kaduna. Farm land soil, forest soil and granulated iron stone soil were sourced within the college premises and FRIN/JICA plantation. Jatropha curcas seedlings were sown on the different soils and each was replicated eight (8) times. The experiment was laid out in Complete Randomized Design (CRD). Growth parameters were collected forth nightly and was subjected to Analysis of Variance (ANOVA) and Duncan Multiple Range Test (DMRT). Results revealed that there are significant (P>0.05) difference in the height, stem diameter and number of leaf among the three different soil for the growth assessment. The growth rate recorded from the farm land soil are statistical higher (P>0.05) in leaf width, plant height and stem diameter than the other two soil while the growth parameters assessed were significantly lower (P>0.05) in iron stone soil and forest soil. It is recommended based on the parameters assessed that soil from the farmland gives the best result for raising and nurturing of J. curcas in the nursery without addition of any plant nutrient media.

SUMMARYProlonged inability of yam tubers to sprout/germinate is associated with the expression of tuber dormancy, and the start of dormancy in tubers is linked to the onset of tuber formation. Although the plant hormone, abscisic acid (ABA) is known to regulate the onset and maintenance of dormancy in tubers, there are no known method(s) of inducing shoot growth (sprouting) on seed yam tubers that are harvested at 240 days after vine emergence or earlier. Therefore, this study was conducted to: (1) determine whether the absorption of fluridone, a reputed ABA inhibitor, prior to or during early seed yam tuber formation would induce sprouting, and (2) determine the effect of fluridone on early shoot growth. The study was a 2×4 factorial experiment arranged in a Completely Randomized Design (CRD) with eight treatment combinations replicated three times. Two species of yam with long dormancy durations were used: D. rotundata var TDr 131 and D. alata var TDa 98/01166; and three concentrations of fluridone were tested (30, 50, 100 µM). Young plants (69 days after vine emergence) of TDr 131 and TDa 98/01166 were grown in a coco coir medium hydroponics system using Hoagland's Nutrient Solution, with or without the test fluridone concentrations. In all fluridone treatments, most leaves of both species of yam had 30–90% of their surface bleached while the stems appeared purplish. In both Controls, all the newly formed seed tubers that were harvested at 90 and 104 days after vine emergence were dormant (devoid of any new shoots/sprouts). In contrast, over 70% of the seed tubers that developed in 30 and 100 µM fluridone had at least one new shoot, particularly in TDa 98/01166. The fluridone treatments did not significantly affect tuber weight or vegetative growth parameters like dimensions and number of leaves. This study has shown that the duration from vine emergence of the old tuber to sprouting of the new tuber can be reduced by more than half if young plants absorbed fluridone during early tuber development.

The increasing demand for the “Miracle Tree”, Annona muricata, also known as Sour sop has led to the need for increased production. However, the importance of appropriate growing media for the propagation of this seedling cannot be over emphasized. This experiment was conducted in 2019 at the screen house of the Soil and Tree Department of Forestry Research Institute of Nigeria, Ibadan, Oyo State to evaluate the effect of different composted media on the growth Annona muricata L (Sour sop). The experiment was laid out in Complete Randomized Design with sixteen (16) treatments and three replicates. Data on growth parameters were collected and analyzed using Analysis of Variance (ANOVA). Means were separated using Duncan’s Multiple Range Test at 5% probability level. It was observed that treatment A2 (80: 20; soil: OF; v/v) performed significantly higher in, number of leaves, plant height and stem girth followed by treatment A3 (60:40; soil: OF; v/v). This study concluded that the growing media or treatment A2 (80: 20; soil: OF; v/v) was optimum for the growth of Annona muricata.

Ginger (Zingiber officinale Rosc.) Is one type of rhizome plant commonly used as a medicinal plant or spice. The rhizome is aromatic and has a distinctive odor used by the community to be used as spices, cooking ingredients and medicinal sources. So far the results of ginger production have not been able to meet people's consumption needs due to a decrease in ginger production at the main ginger development center (West Java). One of the main constraints of ginger cultivation is the attack of bacterial wilt disease caused by the bacterium R. solanacearum. One effort that can be done in tackling bacterial wilt in ginger plants is by using clones that are resistant to bacterial wilt disease of R. solanacearum. The experimental design was carried out using factorial Completely Randomized Design, using ginger clones and the application of R. solanacearum bacteria. This design consists of 6 treatments and 4 replications. Each replication unit consists of 4 plants, so the total number of plants used is 96 plants. The experimental results were analyzed using regression correlation analysis on the parameters of disease progression, while on plant growth parameters using variance analysis and if there were significant differences then continued with Duncan Multiple Range Test (DMRT) with a confidence level of 95%. The results showed red ginger clones including rather resistant criteria with a severity value of 25% while ginger empirical clones and elephant ginger clones were critically vulnerable with 75% severity values and 85.42%. Red ginger clones are more responsive to the infection of R. solanacearum bacteria so that the highest phenol content increases compared to other clones of 0.297 mg/ml, the phenol compounds that play a role in increasing plant resistance. In the variable growth of ginger emprit clone plants have a higher plant height and number of leaves compared to other clones, namely 43.83 cm and 15.44.

A pot experiment was carried out at the grill house of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during the period from December 2013 to April 2014 to study the growth, morpho-physiological, yield and yield contributing characters of twenty sorghum genotypes. The experiment was consisted of twenty genotypes of sorghum viz., BD 700, BD 701, BD 702, BD703, BD704, BD705, BD706, BD707, BD708, BD709, BD710, BD712, BD720, BD721, BD722, BD725, BD726, BD727, BD728 and BD729. The experiment was laid out in a Completely Randomized Design with three replications. The collected data were analyzed statistically and the means were adjudged by Duncan’s multiple range test at 1% level of probability. Among the genotypes, BD 725 showed significantly the best performance on growth, yield and morpho–physiological characters compare to other genotypes at harvest, while BD728 was less efficient among those parameters. As a result, highest plant height (251.20 cm), panicle plant–1 (2.83), highest 1000–grain weight (27.10 g), highest grain yield (3.58 t ha–1), straw yield (16.05 t ha–1) and biological yield (19.64 t ha–1) was recorded from BD 725 at harvest. However, number of leaves, leaf area plant–1 and Leaf area index had also significantly highest (18.33 and 5542.0 cm2 and 2.81, respectively) in BD 725 at 90 days after sowing. BD 725 further recorded the highest growth of cumulative growth rate (32.54 g m–2 day–1) at the stage between 60–90 days after sowing thereafter they decreased. All the above growth, yield and morpho–physiological characters were less effective in BD728. On the basis of these results, BD 725 was found outstanding for plant growth, yield and morpho–physiological characters of sorghum.Asian J. Med. Biol. Res. June 2015, 1(2): 271-284

This research examined the effect of pod elimination on growth and N2 fixation ability in three annual Medicago species during drought stress and subsequent recovery. This study was carried out as a factorial experiment based on a completely randomized design with four replications. The treatments included annual Medicago species, presence or removal of the pod, and water stress at four levels: 100% (as a control), 80%, 60%, and 40% field capacity (FC) during the period of stress. The results showed that annual Medicago species can be considered as semi-drought tolerant species and their recovery ability from mild and moderate drought stress is relatively good. M. polymorpha performed better and showed higher recovery ability in comparison with other tested species. The results of this study showed that elimination of pods from annual Medicago species before sowing enhanced seedling performance under drought stress. However, the effect of pod elimination showed higher significance on growth parameters than nitrogen fixation. The information from this research would be useful for better understanding the physiological basis of changes in drought resistance, as well as targeted breeding programs, to improve the performance of annual Medicago species under conditions of limited or scarce water supply.

The availability of water for plants will affect the process of plant growth. Water stress in plants can be overcome by applying fertilizer. Fertilizing through leaves has the advantage of absorbing nutrients needed to speed up the growth process. The purpose of this research was to use a completely randomized design (CRD) with two factors, namely the A factor of water supply consisting of 100% field capacity (KL) (A1), 75% KL (A2), 125% KL (A3), B concentration factor leaf fertilizer consists of 0 g/L (B1), 1,5 g/L (B2), 2 g/L (B3), 2,5 g / L (B4), and 3 g/L (B5) so that there is 15 combinations of treatments with 5 replications. Based on the results of research on the stress conditions of 75%, 100%, and 125% KL the best leaf fertilizer for growth of mustard green plants which includes leaf area, amount of chlorophyll, number of leaves, wet weight, dry weight, and root-shoot ratio is as much as 3 g/L.
