    Despite the importance of tomato in human nutrition, occurrence of drought stress constitutes a major bane to its bountiful production. Therefore, this experiment was conducted to determine the effectiveness of organic mulch in improving growth, yield and quality of water stressed tomato. The experiment was laid out in randomized complete block design (RCBD) with three replications. The six treatments used in the experiment were normal irrigation with zero mulch, drought stress with zero mulch and drought stress with mulch at the rates of 10tons/ha, 15tons/ha, 20tons/ha and 25tons/ha. The organic mulch material used was maize husk and the tomato variety tested was Platinum 107 F1. Water deficit treatment was imposed at flowering stage (five weeks after transplanting (5WAT)) by applying 50% field capacity as irrigation water. Data were collected on plant height, number of leaves per plant, number of branches per plant, number of flowers per plant and mass of fruit yield per plant. Furthermore, leaf proximate compositions (crude fat, crude protein, crude fibre, ash content and dry matter) and leaf chlorophyll content were determined. All the data collected were subjected to analysis of variance (ANOVA) and significant means were separated using least significant difference (LSD) at 5% probability level. Results from this research work showed that stressed plants without mulch application had a drastic reduction in all the measured parameters. The plants subjected to drought and treated with 20tons/ha mulch showed higher plant height, number of branches and yield as well as chlorophyll, fiber and ash content compared to the plants treated with 10tons/ha, 15tons/ha and 25t/ha mulch. It is, therefore, concluded that 20tons/ha mulch be used for alleviating drought stress condition in Platinum 107 F1 tomato variety in the study area when all the conditions in this research are maintained.

    (West University of Timisoara, Romania, 2021-08-28) Kareem, I; Ismail, M.R; Puteh, A.B; Kareem, S.A; Lawal, O.I; Adekola, O.F; Faseyi, A.F; Olaniyan, J.O; Yusuf, S.Y; Lawal, M.T; Abdulkareem, K.A; Olayinka, B.U; Abdulaziz, A.; Ahmed, O; Baba, H.S; Kuranga, H.A; Lawal, Q.O; Musa, A.I; Oyelade, H.Y
    One of the potential ways of increasing rice production to cater for ever increasing population of Malaysia is to extend the production area of lowland rice through its production as upland rice. Therefore, this research was conducted to determine the effects of seed priming in alleviating water deficit stress in lowland rice produced as upland rice. The treatments used were 100mM calcium chloride dihydrate for duration of 48hours and temperature of 25oC, 40% w/v polyethylene glycol (PEG) 6000 for a duration of 48hours and temperature of 25oC, 100ppm kinetin for a duration of 24hours and temperature of 4oC, 200ppm methyl jasmonate for a duration of 24hours and temperature of 4oC, stressed control (unprimed seeds) and the unstressed control (unprimed seeds with adequate irrigation). The experiment was laid out in randomized complete block design (RCBD) with three replications. Data were collected on classical growth parameters, germination pattern, gas exchange characteristics, yield and yield components. It was found that priming MR219 rice with PEG could enable the variety to be produced as upland rice with little yield reduction because PEG priming was the best in individual seed mass, final yield, harvest index and water use efficiency. It is, therefore, concluded that 48hours of priming with 40%w/v polyethylene glycol at 25oC be used for MR219 rice seeds whenever MR219 rice variety is to be cultivated as upland rice.

    (Agricultural Academy of Bulgaria, 2020-04) Kareem, I; Faseyi, A.F; Saliu, A.K; Abdulmaliq, S.Y; Adekola, O.F; Abdulkareem, K.A; Olayinka, B.U; Abdulaziz, A.; Alasinrin, S.K; Hakeem, A.K; Usman, M.; Lawal, M.T; Ahmed, O; Lawal, O.I; Bello, W.B; Salami, T.B; Ayeleke, D.A; Azeez, K.O; Olaniyan, J.O; Affinnih, K.O; Olalekan, K.K
    This experiment was conducted to determine the effects of drought stress on growth yield, NPK partitioning and nutritional composition of okra. To achieve this objective, four levels of water deficit stress (daily (control), a day interval, two days interval and three days interval irrigation) were tested on 17Lucky19 (hybrid) okra variety in a pot experiment. The experiment was laid out randomized complete block design (RCBD) with three replications. Parameters used to determine the effects of water deficit stress were nitrogen, phosphorus and potassium contents of stems and leaves. Plant height, number of branches, number of leave, number of fruits, fresh fruit mass, dry straw mass, chlorophyll content, and proximate parameters (crude fat, crude fibre, crude protein and ash contents of the leaves) were also used. It was found that all the growth and yield parameters tested reduced with increase in water deficit levels. Similarly, all proximate parameters decreased with increase in water deficit levels with the exception of crude fibre which increased with increase in water deficit levels. In the same vein, nitrogen and potassium levels decreased with increase in water deficit levels in both leaves and stems. However, phosphorus levels in stems and leaves decreased with increase in water deficit levels. It is, therefore, concluded that 17Lucky19 is susceptible to water deficit stress. This implies that water deficit tolerant or resistant varieties should be used instead of 17Lucky19 whenever areas with irregular rainfall are to be used for cultivating this variety of okra.

    (Agricultural Academy of Bulgaria, 2020-04) Kareem, I; Kareem, S.A; Abdulmaliq, S.Y; Adekola, O.F; Abdulkareem, K.A; Olayinka, B.U; Abdulaziz, A.; Yusuf, A.S; Kuranga, A.B; Magaji, U.; Lawal, M.T; Ahmed, O; Lawal, O.I; Bello, W.B; Salami, T.B; Ayeleke, D.A; Azeez, K.O; Olaniyan J,O; Affinnih, K.O; Olalekan, K.K
    The type of priming chemical and the duration of priming are important factors determining the performance of plants resulting from priming treatment. Therefore, this research was conducted to determine the effects of different priming agents and soaking durations on growth and yield of drought-stressed rice. To achieve this objective, a pot experiment was conducted where three priming agents (100 mM calcium chloride dihidrate (CaCl2), 40% (w/v) polyethylene glycol (PEG) 6000 and 100 ppm kinetin) combined with two soaking (priming) durations were tested on drought stressed rice plants in a 3x2 factorial experiment. The experiment was laid out in a completely randomized design (CRD) with three replications. Parameters on germination percentage, number of tillers, number of productive tillers, tiller effi ciecy, shoot fresh and dry weight, yield, seed length to seed width ratio (seed size), 100-seed weight and harvest index were taken. Also, data on photosynthetic rate, stomatal conductance, intercellular carbon-dioxide and transpiration rate and leaf water were taken. It was found that the highest yield was got when PEG was used for priming for 48 hours. It was found that number of tillers, shoot dry mass, 100-seed mass, rate of photosynthesis, stomatal conductance, transpiration and leaf area water were increased when seeds were primed for 48 hours with kinetin solution. However, tiller efficiency, harvest index and seed size were favoured by 24-hour priming with PEG while number of productive tillers, shoot fresh mass and grain yield were favoured by 48 hour priming with PEG. It was concluded that 48 hour priming with PEG was effective alleviate moisture stress in MR219 rice. This implies that to avoid wastage of priming chemicals and circumvent undue prolongation of priming period or duration which will result in harming the seeds (toxicity) and poor performance of the resulting plants, 40% (w/v) PEG 6000 should be used for 48 hours for priming MR219.

    (General Sir John Kotelawala Defence University, Sri Lanka, 2017) Olawuyi, B.O.; Amali, I.O.O.; Lawal, M.T
    This study examined the primary school’s teachers’ knowledge of learning disabilities in Ilorin West Local Government, Kwara State. The study was a descriptive design of survey, a sample of 150 primary schools were selected using simple random procedure out of a total population of 1,837 primary school teachers` in Ilorin West Local Government Area. A 10 items researchers designed questionnaire with psychometric properties of content validity, and 0.65 reliability index was used to elicit the needed data from the respondents. Frequency counts and percentage were used for answering the research questions. The findings of the study showed that; majority (62.67%)of the teachers did not know that head injuries, nutritional deprivation and exposure to toxic substances can contribute to learning disabilities. Also a good percentage (51.3%) of the teachers did not know that children with learning disabilities do have problem understanding body language and facial expression. Based on the findings, it was among others recommended that the school authorities should employ professional educational psychologists to teach the teachers about class management with a view to decreasing distraction for pupils with learning disabilities

    Stressful Effect of Different Rates of Nitrogen Starter Dose on Nodulation, Growth, Proximate Composition and Yield of Soybean (Glycine max)
    (Nigerian Institution of Professional Engineers and Scientist, 2022-05-29) Isiaka, K; Lawal, Q.O; Olayinka, B.U; Abdulkareem, K.A; Lawal, M.T; Yusuf, S.Y
    Despite the fact that high nitrogen content in the soil can impede nodule formation in soybean, the need for addition of nitrogen fertilizer as a starter dose to supplement the actions of N-fixing bacteria is a necessity because it restores the drained nutrient and results in high yield. To evaluate the stressful effects of different rates of N fertilizer starter dose, a pot experiment was conducted to evaluate the effect of N fertilizer starter dose on nodulation, growth, proximate composition and yield of soybean. Urea was applied at the rates 0, 50, 75 and 100 kgN/ha at planting using side placement method. The experiment was laid out in Randomized Completely Block Design (RCBD) with three replications. Growth assessment was through taking data on plant height, number of branches, number of leaves and internode length. Also, data on nodulation, yield and yield attributes were taken. Proximate compositions (crude protein, crude fat, crude fiber and ash content) were also determined. It was found that 100 kgN/ha of N-fertilizer improved the total nodulation by 33.95% compared with the control. The yield was greatest with application of 100 kgN/ha compared with other application rates because there was 20% yield increase compared with the control. For the proximate composition, crude protein content was 7% above the control with application of 50 kgN/ha. Furthermore, crude fat content was 37% better than the control with the application of 100 kgN/ha. It was concluded that for profitable soybean production in the study area, the use N fertilizer like ureaat 50 kgN/ha as a starter dose is recommended because of its cheapness and high yield that resulted from its application to the crop. Finally, nitrogen starter dose up to 100kgN/ha did not constitute stress to production of soybean variety under test.
