This study investigated the effects of potting media on seed germination and early seedling growth of Pterocarpus erinaceus Poir at the Forestry Nursery in Jos, Nigeria. Using Completely Randomized Design (CRD) with three replicates, laboratory-tested soil samples, top soil, sharp sand, sharp sand + top soil, sharp sand + top soil + cow dung and sharp sand + top soil + poultry droppings were used in various combinations to assess the growth parameters of P. erinaceus (germination percentage, emergence, plant height, number of leaves, length of leaves and stem diameter) for 12 weeks. Descriptive and inferential statistics were employed to analyze collected data. Result indicated that sharp sand + top soil + poultry droppings had the highest nitrogen concentration (2.19%), sharp sand + top soil + cow dung (2.07%), sharp sand + top soil (1.50%), top soil (0.72%) and Sharp sand (0.38%). Potting media with poultry droppings recorded an overall higher percentage germination of 42.9% by the end of the germination period. Analysis of variance (ANOVA) of collected data on combined soil aggregate on growth parameters indicated a significant (p<0.05) difference in plant height, number of leaves, leaf length and stem diameter. Potting with poultry dropping gave the best potting media growth results when compared to other treatments that enhanced seed germination and seedling growth of P. erinaceus. This superior observation of the poultry droppings incorporated potting mixtures over the cow dung provides an outstanding potentials to enhance P. erinaceus plantation establishment. Consequently, recommended for raising seedlings in the nursery as well as ensuring sustainable management.

Biochar Amendment

The first objective of this study was to assess the effects of coconut shell biochar in propagation substrate on seed germination and seedling growth of Coreopsis grandiflora (Hogg ex Sweet) ‘Early Sunrise’, Leucanthemum ×superbum (Bergman ex J. Ingram) ‘Silver Princess’, and Eschscholzia californica (Cham.). Cornell seed germination mix was amended with the biochar (0%, 5%, 10%, 20%, or 40%, v/v). Seed germination and seedling growth were determined during a 21-day period in two germination rooms. This particular biochar amendment did not affect final germination percentage for any of the species. All three species had seedling shoot and primary root length growth with low to moderate positive correlation (r = 0.33–0.54) with coconut shell biochar amendment volume. Coreopsis seedling dry weight was significantly higher with 40% biochar than the control (P ≤ 0.05). The second objective of the study was to compare digitally collected data with manually collected data. Two-dimensional scans of Coreopsis and Leucanthemum seedlings were collected. Seedling dry weight (mg) and seedling length (mm) predicted seedling two-dimensional area for Coreopsis (R2 = 0.73, P < 0.001) and Leucanthemum (R2 = 0.87, P < 0.001). Digitally traced shoot and root lengths were strongly positively correlated (r = 0.99–0.97) with manual ruler measurements, suggesting that digital imaging could replace manual length measurements. The results of this study suggest inclusion of this particular coconut shell biochar in seed germination, and establishment substrates can have neutral or positive effects on herbaceous perennial germination and establishment.

Herbicides are the most flourishing weed control knowledge eternally developed. To appraise the possessions of herbicides on maize, a study was carried out to evaluate the effect of alachlor on different maize cultivars on germination and early growth parameters. The  studies were carried out in hydroponic conditions supplemented with different concentrations (1.0, 2.5 5.0, 7.5 and 10.0 ppm) of alachlor. All the three cultivars of maize were found to be significantly affected with increasing herbicide concentration. Percent germination, vigour index, tolerance index, fresh and dry weight, plumule and radicle length were found to be decreased as the herbicide concentration increased, however the dry weight increased slightly at higher concentration when compared to other concentrations. The percent toxicity increased as the concentration of herbicide increased. The current study clearly implies that higher concentration of alachlor is toxic to maize, resulted in a decline in seed germination and early growth parameters.DOI: http://dx.doi.org/10.3126/ijls.v9i4.12638

Smoke Water

The ecologic significance of smoke-related seed germination is now well recognized. Consequently, smoke solutions and a pure butenolide, the active compound from smoke that stimulates germination of a number of plant species, show great potential for enhancing the growth of vegetable crops. Achieving maximum production and better and faster growth of the seedlings has always been a priority for vegetable growers. This study therefore highlights the effects of foliar application of smoke-water and a butenolide on seedling growth of okra [Abelmoschus esculentus (L.) Moench] and tomato (Lycopersicon esculentum Mill.). Treating okra seedlings with smoke-water (1:500 v/v) showed a significant (P < 0.05) increase in shoot/root length, shoot fresh/dry weight, number of leaves, total leaf area, and stem thickness compared with the control treatment. Treatment of okra seedlings with smoke-water significantly (P < 0.05) increased the absolute growth rate (AGR) per week. However, the seedling vigor index (SVI) did not improve as a result of no change in root fresh weight. On the other hand, foliar application of smoke-water and butenolide showed a pronounced effect on the seedling growth of tomato. Most of the growth parameters examined for both the treatments were significantly (P < 0.05) increased, resulting in a significantly (P < 0.05) higher SVI and AGR than the control. This study indicates that the foliar application of smoke-water or butenolide may be a useful and inexpensive technique for enhancing seedling growth of vegetable crops.

Background: Rice (Oryza sativa L.) is a major cereal crops planted in Thailand for both local consumption and export. The objective of this study was to investigate the allelopathic effect of Caesalpinia sappan L. and Crateva magna (Lour.) DC. extracts in promoting a rice cultivar, Khao Dowk Mali 105 (KDML105) seed germination and seedling growth, at 7 and 14 days after sowing (DAS). Methods: The C. sappan and C. magna plants were cleaned with tap water and air dried in room temperature then cut into small pieces and ground into fine powder. Plant crude extracts was prepared using ethanol as solvent. Result: The results showed that rice seed treatment with C. sappan and C. magna extracts was significant (all p less than 0.05), increasing root length, shoot fresh and dry weight and root fresh and dry weight of rice seedlings at 14 DAS. Seed treatment with these two plant extracts led to a significantly greater vigor index of the KDML105 rice seedling cultivar, when compared with the control. Interestingly, the seed treatment with C. magna extract at a 100 ppm concentration was found to produce the highest enhancement in the overall rice seedling growth parameters, including the vigor index of seedlings. The results showed that a low concentration of C. magna extracts can be potentially used in promoting seedling growth of rice since they improved the overall growth parameters.

The effect of root exudates of fifty Sorghum genotypes on seed germination and seedling growth of millet were studied in vitro. The fifty genotypes were divided into four groups according to their effect on percentage reduction in root and shoot and whole plant average lengths of millet seedling growth. The first group caused slight stimulation, the second slight inhibition, the third gave limited inhibition and the fourth caused high inhibition. In seedling growth. Five genotypes of sorghum were selected, one from group two and four from group four. These five genotypes were cultured in the field in Autumn 2007 and at the end of the season plants were removed, dried and grind. Three concentrations of each of these genotypes powder were prepared, in addition to the control treatment, (0.0, 3.0, 6.0 and 9.0) g/kg soil to study their effects on the growth of Amaranthus retroflexus which cultured in pots and kept in experimental field. Data on number of leaves, lengths of shoot and root and whole plant were taken as well as wet and dry weight were measured. Percentage of Amaranthus retroflexus seeds germination were evaluated in an experiment cultured in Petri dishes containing concentrations (0.0, 5.0 and 10.0%) of aqueous extracts of each of the five genotypes powder. Results showed high significant inhibition for the four genotypes from group four in comparison with the one genotype from group two. Significant differences among these genotypes in their inhibition on such parameters as shoot, root, whole plant growth, number of leaves, and wet and dry weight. The genotype 2005-K-Type 1050 gave the highest reduction in plant length 53.2% incomparing with the genotype 2005-K-Type 1033 which gave 0.7%. The percentage of seed germination of Amaranthus retroflexus was significantly reduced as the concentration of the aqueous extract increased and there were significant differences among genotypes on this parameter. The concentration of the powder of each genotype added to the soil produced significant reduction in all parameters studied and the effect increased as the concentration increased in soil. This research discusses the potential of the allelopathic effect of some Sorghum genotypes on weed germination and growth reduction and the possibility of employing them in weed control program with the intention to use less herbicide.

The objective of this study was to assess the feasibility of utilizing composted municipal yard waste as a component of potting media, which is predominantly composed of peatmoss, a nonrenewable and increasingly expensive medium. Green Comet broccoli (Brassica oleracea L. Italica group) was grown in five ratios (1:0, 1:2, 1:3, and 0:1) of composted yard waste: commercial soilless potting medium. Plant heights were recorded weekly. At the end of 6 weeks, measurements were taken on plant height, fresh weight, dry weight, and root: shoot ratios. Media leachate was tested for pH and soluble salt levels. Germination tests were run using the same potting mix ratios. Percent germination and seedling survivability were recorded. Results show that yard waste compost can be used as a component of potting media, although seed germination and seedling growth are inhibited at high compost levels.
