Influence of urea fertilizer on early growth of African Rose Wood (Pterocarpus erinaceous Poir.) seedlings in Kaduna State, Northern Nigeria

Influence of urea fertilizer on early growth and development of Pterocarpus erinaceous seedlings were investigated. Two hundred (200) uniformly growing seedlings were transplanted into polythene pots filled with top soil. Four urea fertilizer rates (0.035; 0.065; 0.095; 0.0125 g) and control were applied to the seedlings in the pots 20 × 25 × 25 cm, filled with 800 g of top soil collected from forest plantation. Assessment on the metrical character of the seedlings was done fortnightly. The fertilization of the selected seedlings with urea fertilizer was done round the seedlings in the nursery pots using ring method. The experiment was laid out in a completely randomized design. The data were subjected to analysis of variance, and means were separated using Duncan’s multiple range test at p < 0.05. The results show that fertilizer rates had significant (p < 0.05) effect on the growth and development of seedlings of P. erinaceous. Seedlings treated with 0.095 g of urea produced the highest mean values of 12.00 ± 0.66 cm; 0.33 ± 0.01 mm; 190 cm2 and 12.65 ± 0.67 for stem height, collar diameter, leaf area (LA) and number of leaves respectively. Seedlings fed with 0.125 g had the lowest values of 11.19 ± 0.61cm for height, 0.32± 0.01 mm for collar diameter 11.54 ± 0.70 for number of leaves and 124 cm2 for the LA. Urea fertilizers had significant effect on the early growth of the seedlings, therefore fertilization at 0.095 g per pot is recommended for raising P. erinaceous seedlings.

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.

ABSTRACT This research aimed to characterize the biometry of seeds, the morphology of seedlings and to evaluate the initial growth of blue jacaranda trees (Jacaranda mimosifolia D. Don.) in two environments with distinct luminosity. The biometry of 100 de-winged seeds was measured by their length, width and thickness. One hundred seeds were sown into 300 cm3 tubes and seedlings morphology was registered throughout the germination process using digital photographs disposed sequentially according to seedlings age. The initial growth analysis was performed in two environments, full sun and greenhouse, during nine periods, and arranged in a complete randomized design with subplots. The response variables were: number of leaves, plant height, collar diameter, root length, aerial and roots dry weight, and Dickson’s Quality Index (DQI). Biometry results showed seeds 7.09 - 9.26 mm long, 6.74 -9.39 mm wide, and 1.11 -1.89 mm thick. Germination is of hypogealphanerocotylar type, with first root arising six days after sown. Plants at full sun presented larger collar diameters, greater root dry weight and higher DQI as evaluation periods passed by. In conclusion, the biometry of seeds and the morphology of seedlings of blue jacaranda can be used to recognize this species in the field. Plants at full sun presented better development. Seedlings cultivated at full sun can be destined to recuperate forests and degraded areas just 36 weeks after sowed.

ABSTRACT: Weeds reduce the productive potential of crops. Plants of the Ipomoea genus, besides competing for water, light, space and nutrients, create problems in crop harvests due to their volatile stems. The objective of this work was to evaluate the growth and development of five Ipomoea species. For such, Ipomoea grandifolia, Ipomoea hederifolia, Ipomoea nil, Ipomoea purpurea and Ipomoea quamoclit plants were analyzed during the summer and winter season. Five destructive and periodic growth evaluations were carried out for each study, where leaf number, leaves, stems, roots and the total biomass were analyzed. Phenological stages of the plant development were also evaluated for emergence, flowering and maturation sub-periods by degree-days, totalizing five treatments, conducted in a completely randomized design with four replicates. The phenology averages were analyzed according to the Hess scale, and the growth data through nonlinear regressions. I. quamoclit and I. grandifolia obtained the highest number of leaves in the summer and the winter, respectively. I. nil obtained greater accumulation of leaf and stem dry biomass in both seasons. I. grandifolia obtained greater root development in both periods. I. quamoclit presented reduced cycle times when compared to the other species, especially I. hederifolia and I. grandifolia, which presented larger cycles. Based on the results, I. grandifolia probably shows greater interference with agricultural crops due to high root growth, high leaf production and longer cycle. Shorter-cycle species, such as I. quamoclit, when present, should require shorter residual control periods.

Bougainvillea Spectabilis

Abstract Bougainvillea spectabilis is an ornamental plant grown in both temperate and tropical zones. They are primarily propagated by stem cuttings; however, difficulty in growth at early stages occurs routinely, causing barrier for its mass propagation. This study was conducted to study the effects of integrating compost with Trichoderma longibrachiatum (NGJ167), in improving the early growth of Bougainvillea spectabilis. Trichoderma longibrachiatum (NGJ167) used for this purpose was obtained from the Bioscience Center, International Institute of Tropical Agriculture (IITA), Ibadan. One hundred and twenty (120) pots were filled with 5 kg top soil each from an alfisol. Treatments included: Top soil as Control (C), Top soil inoculated with T. longibrachiatum (T), Top soil + compost at 5, 10 and 15 t ha-1 as C1, C2, C3 respectively, Top soil inoculated with T. longibrachiatum + compost at 5, 10 and 15 t ha-1 as C1T, C2T, C3T respectively. The eight treatments were arranged in a completely randomized design (CRD) and replicated three times. Results indicated that integrated use of compost with Trichoderma significantly (p < 0.05) had higher growth values than the control. Higher plant height, stem diameter, number of branches and number of leaves, were recorded with the use of compost at 10 t ha-1 compared to control. Compost with Trichoderma gave higher shoot dry weight compared to treatments of compost alone. In conclusion, use of compost alone or inoculated with Trichoderma had significant effect on early growth and development of Bougainvillea spectabilis.

Background and Objective: Unproductive soil has been a major problem to farmers, recent interest in the use of a stable organic manure (biochar) as soil amendment and poultry manure to increase soil fertility is also increasing. Hence, the experiment was conducted to assess the condition of poultry manure and biochar on the growth and yield of tomato. Materials and Methods: A greenhouse experiment was conducted at the Federal College of Forestry Ibadan, using polyethylene bag with 5 kg soil collected at two (2) soils depths, 0-15 cm and 15-30 cm depth at the botanical garden, Federal College of Forestry Ibadan. The experiment was arranged in a completely randomized design (CRD) with four replicates. The treatments used were poultry manure (5t/ha), biochar (10t/ha), mixture of poultry manure and biochar (1:1) and control (no amendment).The tomato seeds (UC82B) were sourced from NIHORT, Ibadan and raised in a germination basket. Data were collected weekly on plant height, collar diameter and number of leaves, 50% days to flowering and yield of tomato plants from two weeks after transplanting (WAT). Data collected were analyzed statistically using ANOVA while means were separated using LSD (p<0.05) where applicable. Results: In 0-15 cm soil, the growth variables (plant height, number of leaves and collar diameter) increased with various treatments used. The highest tomato height was observed with the application of biochar (10t/ha). All the treatments applied affected the number of tomato leaves at all weeks after transplanting (WAT) with poultry manure 5t/ha having the highest number of leaves at 7WAT, while collar diameter was significantly affected by various treatments from 2 to 5 WAT, with the mixture of P.M + BIO (1:1) recording the highest value and the control plot recorded the least values in all weeks. However, in 15-30 cm soil, there was significant difference in the number of leaves of tomato among all the amended soil from 5 to 7 WAT, the highest tomato leaves were obtained when the soil was amended with poultry manure (5t/ha) and can be compared with other treatments. Interaction of poultry manure and biochar(1:1) and poultry manure 5 t/ha resulted in highest height of tomato plant from 3-7 WAT as compared to the control that had the least value but were not significantly different from the sole application of biochar 10t/ha. Interaction of poultry manure + biochar (1:1) and poultry manure (5t/ha) gave the highest tomato flowering and fruits. Conclusion: Based on this result, biochar and poultry manure when added to soil, boosted the mineralization of the soil after amendment.

Khaya senegalensis (Desr) A. Juss is a perennial deciduous tree which has many uses in developing nations. The population of the tree is rapidly declining due to no conservation efforts to prevent the species from endanger and extinction. At the moment there is dearth information on manure types required to raise healthy seedlings of the tree species in the study area. To conserve this genetic resource, germination and early growth rate experiment was carried out using seeds collected from three locations (eco-zones) (Alkaleri, Bauchi and Toro). Matured seeds of K. senegalensis were collected from mother tree stand in the three locations. One hundred and fifty seeds (150) from each location were sown in perforated polythene pots at an average depth of 2-3 cm. After germination i.e. 30 days after planting, different manures were applied to the seedlings. The experiment was laid out in a Completely Randomized Design (CRD) with three treatments, namely: poultry dung, cow dung and NPK manures; the experiment was replicated four times. Data on seeds germination variables of interest (seedling heights, number of leaves, collar diameter, leaf area, leaf width, leaf length and fresh weights) were measured. Seedlings height were measured using meter rule, collar diameters using a venier caliper, numbers of leaves were determined by manual counting the number of leaves on the seedlings, leaf area was measured by tracing leaves of seedling on a graduated graph sheet. Data collected on seed germination and early growth rate were subjected to descriptive statistics and inferential statistics (ANOVA). Where significant differences occurred, Tukey test was used to separate the means. Based on this finding, germination of seeds commenced after 10 to 14 days. Locations and manure types had significant effects on the mean heights, number of leaves, collar diameter, leaf area, leaf width, length and fresh weights of K. senegalensis seedlings in the study area. Thus, for species conservation and genetic heredity, seeds sourced from Bauchi eco-zone was the best with poultry manure as the best performed manure for the raising of K. senegalensis seedlings in the study area.

Eggplant (Solanum melongena) falls under the fruit species under the family of Solanaceae. It is grown widely throughout tropical and subtropical Zones in the world. It is a good source of phenolics, flavonoids, vitamins, calcium and protein. Due to its high nutritional properties, the demand for eggplant is increasing annually. However, due to limited planting space, it is difficult for the producers to increase the production in order to meet the demand. Thus, the objective of this study is to improve the growth and development of selected physiological characteristics of eggplant with chitosan and salicylic acid. The experiment was carried out in factorial randomized complete block design (RCBD) with 4 replications. This experiment was conducted at Field 15, Universiti Putra Malaysia. The plants were treated with chitosan and salicylic acid at four different rates; 0, 2, 4 and 6 ml/L for chitosan and 0, 50, 100 and 150 mg/L for salicylic acid. The treatments were applied either alone or in combination. Results revealed that the application of chitosan combined with salicylic acid influenced the physiological characteristics of the eggplant compared to the control group. Combination of 4 ml/L chitosan with 150 mg/L salicylic acid gave the highest mean values of plant height (107.13 cm), number of branches (14.91), number of leaves (136.08), total number of flowers per plant (101.8), compared to other treatments. Therefore, due to cost effectiveness and better impact on physiological characteristics the combination of 4 ml/L chitosan and 150 mg/L salicylic acid as foliar fertilizer is recommended to improve the growth and development of eggplant.

Fertilizer Rates

Java lemongrass is commonly cultivated in Vietnam for the use in industries and traditional medicine. Currently, the application of fertilizer, especially nitrogen fertilizer, is one of the most traditional farm practices to increase production yield. A single factorial experiment was carried out in a completely randomized design, three replications to determine the suitability of nitrogen fertilizer rates on growth, leaf and oil yields of Java lemongrass. Six treatments were used in this experiment including 90, 120, 150, 180, 210, 240 kg N/ha and applying 90 kg N/ha as control. Fertilizer base for treatments (for 1 ha) included 20 tons of cow dung compost, 60 kg P2O5 and 60 kg K2O. The application of 120 kg N/ha significantly improved the growth of Java lemongrass as plant height (97.0 cm/plant), average number of leaves (197.1 leaves/plant), average weight of leaves per plant (198.7 g/plant), fully leaf yield (9.4 tons/ha/2 harvest times), essential oil content (1.0% FW) and economic oil yield (97.8 kg/ha/2 harvests).
