The hereby study investigated the effect of Magnesium application at different levels on the morphological parameters and photosynthetic pigment accumulation of Corchorus olitorius. Seeds of C. olitorius were utilized in the experiment. These seeds were sown in 2 big bowls and were supplied with 200 ml of water every day until they were fully established. After three weeks of sowing, the seedlings were transplanted into plastic pots. The treatments were: distilled water (control); nutrient solution in which the concentration of Magnesium was increased by the factor of 5 (N5), nutrient solution in which the concentration of Magnesium was increased by the factor of 10 (N10) and nutrient solution lacking Magnesium source (NMg). The seedlings were then divided into 4 regimes, with each regime containing each treatment. From the results obtained, it was observed that there was a significant effect at (P≥0.05) on the Corchorus olitorius growth parameters and photosynthetic pigment accumulation among the treatments. There was an increase in the shoot height, number of leaves, number of flowers, leaf area and the photosynthetic pigment accumulation in the seedlings treated with magnesium increased by the factor of 5 (N5) than by other treatments. The control recorded the lowest values for these parameters. It can be concluded that for an optimum growth of Corchorus olitorius, it can be inferred that the plant can do well in nutrient solution having Magnesium source (at moderate level).

This study aimed at determining the responses of some of the growth parameters of Lycopersicum esculentum to light and nutrient stress. The focus is equally orientated in determining the effect of light and nutrient stress on the photosynthetic pigment accumulation in plants. Tomato seeds were grown in pretreated sand and were watered with distilled water until the experimental culture was fully established. After this, the plants were transplanted into 60 plastic pots, with holes bored at the bottom to allow proper drainage of the excess water during the course of the experiment. The plants were divided into four groups of fifteen pots each. A group of plants was submitted to stress of nutrient lack by only administering 100 ml of complete nutrient solution, once every four days. The nutrient solution if applied daily was considered to be adequate for the plants. Another group of plants was lightly stressed, by placing them under shade, while adequate light was gotten in direct sunlight. Sampling was carried out at weekly intervals, starting from the seventh day after the first treatment. Plants were randomly picked from each of the four treatments. Three replicates were used for each parameter. The results showed that there was a reduction in photosynthetic pigment accumulation in the plants when both light and nutrient were limited. The data obtained from the study were first tested between normality and assumption of constant variance. A two-way analysis of variance (ANOVA) was carried out considering both factors (light and nutrient ) as source's of variation to investigate the effects of full light and full nutrient (FLFN ), full light and partial nutrient (FLPN), partial light and full nutrient (PLFN) and partial light and partial nutrient (PLPN) the parameters studied in Lycopersicum esculentum.

The objective of this study was to investigate the growth parameters and plant biomass of tomato (Solanum lycopesicum) evaluated under different levels of boric acid, major source of boron. The treatments were; Normal nutrient solution (control, boric acid conc. = 0.000308 g l-1); nutrient solution in which the concentration of boric acid increased by the factor of 5 (boric acid x5, boric acid conc. = 0.00154 g l-1); and nutrient solution in which the concentration of boric acid was increased by the factor of 10 (boric acidx10, boric acid conc. = 0.00308 g l-1). Morphological attributes determined were shoot height, number of leaves, leaf area, shoot, leaf and root fresh and dry weight, and growth indices. Shoot height, number of leaves, leaf area, shoot, leaf and root fresh and dry weight, and growth indices in the seedlings treated with boric acid increased by factor of 10 (boric acid x10)were greater than other treatments. It can be concluded that nutrient solution of boric acid increased by a factor of ten improve the growth parameters and plant biomass of tomato.

Screening for Fe deficiency tolerance in okra (Abelmoschus esculentus) Bangladeshi genotypes (‘BARI-1’, ‘Local variety’, ‘Orca Onamica’, and ‘Prince’) were studied based on different morphological and physiological parameters. Number of leaves, shoot height and weight were significantly reduced in ‘Orca Onamica’ and ‘Prince’, whereas ‘BARI-1’ and ‘Local variety’ did not show prominent decrease in the aforesaid growth parameters under Fe deficiency. Again, ‘Orca Onamica’ and ‘Prince’ showed significantly decreased root length and root biomass under Fe deficiency. In contrast, these parameters were unchangeable in ‘BARI’-1 and ‘Local variety’ in Fe shortage compared to controls. Furthermore, Fe deficiency caused severe decrease in chlorophyll (a and b) and Fe concentrations in leaves of ‘Orca Onamica’ and ‘Prince’ grown on hydroponic culture. In contrast, chlorophyll (a and b) and Fe concentrations were not significantly decreased in ‘BARI-1’ and ‘Local variety’ due to Fe deficiency. Based on these findings, tolerance to Fe deficiency in these okra cultivars can be categorized as: tolerant (‘BARI-1’ and ‘Local’), and sensitive (‘Orca Onamica’ and ‘Prince’). The ranking can be applied in plant breeding program and may have great advantage over conventional methods. This study also demonstrates the effectiveness of hydroponic culture as an efficient method to screen Fe-efficient crop plants.

A nutrient solution experiment was performed using sand culture to evaluate the effects of different glycine levels on the growth and nutrient uptake of coriander (<em>Coriandrum sativum</em> L.). Different glycine concentrations of 0, 5, 10, 20, or 40 mg L<sup>−1</sup> were applied to plants via Hoagland’s nutrient solution in a completely randomized design with four replications and under greenhouse conditions. The results showed that leaf SPAD (soil and plant analysis development; an indicator of leaf greenness) value, stem diameter, and fresh and dry weights of shoots and roots were significantly increased by 10 mg L<sup>−1</sup> glycine in comparison to the control plants. Application of glycine at 40 mg L<sup>−1</sup> reduced many plant growth parameters, whereas leaf proline concentration was increased. All glycine levels except for 40 mg L<sup>−1</sup> increased root fresh weight. Leaf protein content was increased by glycine applied at 10 or 20 mg L<sup>−1</sup>, whereas leaf antioxidant activity was increased at all glycine levels. Application of glycine increased leaf concentrations of nitrogen and potassium (at 10 mg L<sup>−1</sup>), magnesium (at 5 mg L<sup>−1</sup>), and zinc (at all glycine levels) compared to the control plants. The results indicate that moderate level of glycine (10 mg L<sup>−1</sup>) in the nutrient solution can improve the growth and nutritional quality of coriander.

In recent years, the application of silicon (Si) in crops, including coffee, has become a common practice. The objective of this study was to assess the silicon uptake by coffee seedlings and its effects on plant growth, water and macro and micronutrient uptake. The research was conducted using nutrient solution in a greenhouse at the Departamento de Fitotecnia da Universidade Federal de Viçosa, in a completely randomized design with two treatments (with and without silicon) and three replications. Each plot consisted of three plants grown in a 800 mL vessel containing the treatment solutions. At every three days, water consumption, the concentration of OH - and the depletion of Si and K were assessed in the nutrient solutions. After 33 days, the plants were assessed with regard to their fresh and dry weight of leaves, roots and stem, shoot height and total length of the plant (shoot and root). Number of leaves and internodes, and the content and accumulation of silicon, macro, and micronutrients were also determined. The consumption of water, the amount of potassium uptake and, biomass accumulation were greater in plants grown in solution without silicon addition. However, the concentration of OH- in the solution and the amount of silicon uptake were greater in plants grown in solution with added silicon. Silicon accumulation was greater in leaves than in stem and roots. Silicon decreased coffee plant accumulation of phosphorus, potassium, calcium, zinc, copper and iron.

This study determined the best pre–treatment regime required for germination of the seeds of Afzelia africana Sm.Ex.Pers. and also provided information on the early growth parameters of the plant seedlings. Seeds of A. africana were collected from Obafemi Awolowo University, Ile – Ife (Lat 7° 32'N, Long 4° 31'E) and authenticated at the IFE-herbarium. One hundred and twenty five (125) seeds were sown per treatment (n=5 with 5 replicates and 5 repeats). Five (5) seeds each were sown in small petri dishes, without pre–treatment (control), or treated by subjecting to mechanical scarification and chemical scarification using Tetraoxosulphate (VI) acid (H SO ) and Trioxonitrate (V) acid (HNO3 ) for germination studies. Germination counts were made  at an interval of 2 days. For the six different pre–treatments, five seedlings per plastic bowl were transferred into soil in a total of twenty plastic bowls laid out in a randomized design and their growth monitored for 40 weeks. Results showed that pre–treatment of seeds with mechanical  scarification gave the highest percentage germination. Significant differences (P ˂ 0.05) occurred in the shoot height and in the number of leaves between 4 and 12 weeks of growth. The study established that pre–treatment with mechanical scarification was the best for uniform germination of seeds of the plant. This study has provided alternative means of pretreating A. africana seeds apart from using H2SO4 – the first to subject seeds to mechanical scarification and 2 4 chemical scarification using HNO3 , in addition to providing information on the germination parameters and the seedling growth rate of Afzelia africana.

Intensive use of Brazilian pastures without the maintenance of soil fertility has decreased their productivity and favoring the onset of symptoms of nutritional deficiency. The objective of this study was to evaluate the effect of nitrogen, potassium, calcium and sulfur omission in symptomatology, growth and dry mass accumulation in grass Convert. The experiment was conducted in a greenhouse with a completely randomized design, with five treatments and four replications. The treatments were: full nutrient solution, nitrogen omission (N), potassium omission (K), calcium omission (-Ca) and sulfur omission (S). The variables were the number of tillers, leaf number, root size, shoot height, characterization of symptoms of deficiency and shoot and root dry mass accumulation. The data were submitted to the F test by analysis of variance and comparison of means by Tukey’s test (p <0.05). The omission of N, K, Ca and S limited the development of Convert grass compared to the full nutrient solution treatment, reducing the number of leaves, tillers, height, root size and dry mass production. The nutrient omission modified forage morphology, showing visual symptoms of deficiency of each nutrient evaluated. The decreasing order of onset of symptoms was N, Ca, S and K.

This study investigated the responses of maize (Zea mays L.) and cowpea (Vigna unguiculata L. Walp.) seedlings growth parameters to nitrogen nutritional stress. This was with a view to determining whether nitrogen nutritional stress would retard or enhance maize and cowpea growth, partly, wholly or not at all through its effect on biomass accumulation and some morphological parameters. Germination of seeds was done using treated sand in sixty plastic pots. A group of the seedlings was nutrient stressed by administering 200 ml of complete nutrient solution minus nitrogen (-N) while the other groups were fed with five times (X5N) and ten times (X10N) the optimal concentration of nitrogen and the last regime was fed with full nutrient solution (FN). The effects of optimal concentration and nitrogen stress on the growth rates (as measured by their fresh and dry weight) were studied. The result of the growth analysis showed that there was increase in shoot height with supraoptimal concentrations of nitrogen treatments (X10N and X5N) while there was a decrease in shoot height with minus nitrogen (-N) regimes. The observed higher biomass (dry matter yield) under the FN regimes in both Zea mays and Vigna unguiculata were attributed to optimal nutrient assimilation rate.

Vermicompost Leachate

As a result of the growing concerns about the adverse effect of chemicals on the environment, agricultural practices involving organic and environmental-friendly compounds are gaining acceptance globally. Tomatoes remain one of the most popular and widely grown vegetable crops. However, their growth requires a high supplement of nitrogen–phosphorus–potassium (NPK) fertilizer. The effectiveness of vermicompost leachate (VCL) as a potential replacement for the three elements (N, P, and K) during the growth of greenhouse tomatoes was evaluated. Morphological appearance of the tomato seedlings was remarkably enhanced when Hoagland’s nutrient solution (50%) was supplemented with VCL (1:10 v/v). In the absence of both P and K, the addition of VCL significantly (P = 0.05) increased various growth parameters such as shoot length, leaf number as well as shoot and root fresh weight compared with the control tomato seedlings. The detrimental effect of N deficiency on the growth of tomato seedlings was not alleviated with the addition of VCL to the nutrient solution. The photosynthetic pigment content in P-deficient and VCL-supplemented tomato seedlings was significantly higher than the untreated control. The presence of VCL alleviated the detrimental effects caused by deficiency of P and K during the growth of the tomato seedlings. Overall, the use of VCL was beneficial with either complete nutrient solution or in the absence of P and K. Findings of this study suggest that VCL could serve as a potential substitute for P and K deficiency.

A research study on the response of different sweet potato cultivars to different levels of NPK 15:15:15 in Igbariam Anambra State, Nigeria was was conducted between May and July 2018 at the teaching and research farm of the Department of Crop Science And Horticulture, Faculty of Agriculture, Chukwuemeka Odumegwu Ojukwu University (COOU) Igbariam Anambra state.It was a factorial experiment laid out in Randomized Complete Block Design (RCBD) with four replications. Three varieties of Sweet Potato viz; TIS 87/0087, Umuspo 1 and Umuspo 3 were planted. Four fertilizer treatments NPK 15:15:15 at 200kg/ha 300kg/ha 400kg/ha 0kg/ha were applied four weeks after planting. Data was collected at 2 weeks’ interval on growth parameters and yield parameters. Analysis of variance was used to know the significant effect of blocking and treatment on various parameters evaluated and separation of treatment means was done using Fisher’s least significant difference. Sweet potato variety Umuspo 1 was found to produce significantly (P<0.05) large number of leaves and was well established compared to other varieties. Umuspo 3 and Tis87/0087 produced longer vine than Umusopo 1. Generally, increase in fertilizer rate resulted in increase in vegetative growth. TIS87/0087 was best in the overall yield performance when compared to other cultivars. Therefore, NPK 15:15:15 at the rate of 300kg/ha can be recommended for the production of TIS/87/0087 in the study area, further breeding work is also recommended.
