Item Effect of salinity stress on growth, yield and nutritional qualities of two okra varieties(Agricultural Academy of Bulgaria, 2020) Kareem, I; Dauda, Z.I; Kareem, S.A; Abdulmaliq, S.Y; Adekola, O.F; Abdulkareem, K.A; Olayinka, B.U; Abdulaziz, A; Alasinrin, S.K; Usman, M; Mahamoud, A,RThe objective of this study was to determine the effect of salt stress on the growth yield and nutri tional quality of two okra varieties. The experiment was laid out in randomized complete block design (RCBD) with three replications. Clemenson spineless NHA-e varieties of okra were the two varieties tested. The treatments used comprised four salinity levels (0 mM, 25 mM, 50 mM, and 75 mM) us ing sodium chloride as the salinity source. The varieties were assessed using plant height, number of leaves, leaf area, days to first flowering and fruit weight. Furthermore, moisture, carbohydrate, crude protein, crude fat, ash and crude fiber contents were used to assess the fruit nutritional qualities. The results showed that Clemenson spineless variety had better tolerance to salinity stress in plant height, days to flowering, fruit mass, ash content and crude protein content. However, NHA-e variety was more tolerant in fruit dry matter, crude fibre content, carbohydrate content and ether extract content. It is concluded that Clemenson spineless was more tolerant to salinity stress than NHA-e variety. Therefore, Clemenson spineless variety should be used in saline areas of Ilorin which is the northern guinea savannah zone of Nigeria and places with the same edaphic and climatic attributesItem NPK partitioning, growth, yield and proximate composition of okra (Abelmoschus esculentus) under water deficit stress(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.KThis 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.Item Optimization of priming duration for rice production under drought stress(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.KThe 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.
