B; Adediran, Olaotan A.; Ibrahim, Haruna Abstract: Climate change is imparting negatively on global crop production and compromising food security worldwide. To breed for moisture stress tolerance in any given crop, it is important to know the precise water needs of the plants and the growth stage at which moisture stress affect the crop most. Hence, this research aimed at determining the response of onion varieties to moisture stress at different stages of growth. The field experiment was carried out at Maizube Farms Limited field, Minna, Niger State (latitude 903817.10N; longitude 6032i04.20E). The treatments consisted of five varieties of onion (red creole, sivan, prema, wuyan makwarwa, wuyan bijimi) and moisture stress at three growth stages of the plant (flag leaf emergence to two true leaves stage (10-50 days post seeding (PS)), three to seven leaves stage (50-90 days PS), bulb initiation to bulb enlargement stage (90-170 days PS) as well as irrigation throughout the growth stages on a daily basis and at 3 days interval. The 5 x 5 factorial experiments were laid out in Completely Randomized Design (CRD) with three replications. Data were collected on growth and yield parameters. The result obtained shows that the varieties responded to moisture stress in similar ways. Drought stress significantly reduced the growth and yield of the onion varieties tested at all the growth stages compared to plants watered throughout the growth stages at 3 days interval which produced the highest number of leaves, plant height and bulb yield. However, the effect of the drought stress was more critical at the early growth stage (flag leaf to two true leaf stage) reducing bulb yield by 57.74%. Similarly, daily irrigation induced flood stress in onion and significantly reduced onion bulb yield by 59.22% Sat, 01 Jan 2022 00:00:00 GMT http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/29041 2022-01-01T00:00:00Z http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/29040 Title: EFFECT OF SEED SIZE AND POSITION OF SEEDS IN POD ON THE SEED VIGOUR OF FLUTED PUMPKIN (Telfaria occidentalis Hook) Authors: Ibrahim, R. O.; Adediran, Olaotan A.; Ibrahim, Haruna Abstract: Selection of high-quality seeds is important for optimum productivity of fluted pumpkin. This study aimed to evaluate the effects of seed position in pod and size of seeds on the vigour of fluted pumpkin seeds. It was a 3 x 3 factorial combination of 3 seed position in pod viz: anterior, middle and posterior section (close to pedicel) and three seed sizes viz: (big, medium and small). These were arranged in completely randomized design with five replicates. Data were collected on number of days to emergence, percentage emergence, emergence rate index. Data collected were subjected to analysis of variance (using Statistical Analysis System SAS) version of 9.2. The results showed that the first emergence count was observed at 7 days after sowing (DAS) in big and medium seeds. Anterior seeds consistently had the highest emergence percentage at 12-19 DAS. Anterior seeds had the highest emergence rate index value statistically similar to the value recorded in the middle seeds. The medium sized seeds had the significantly highest emergence rate index. It can therefore be concluded that medium sized seeds extracted from the anterior and middle position of fluted pumpkin pods has the potential to give more vigorous seedlings in a non-stressed environment.

S; Adediran, Olaotan A.; Ibrahim, Haruna; Olabisi, O. M. Abstract: This study evaluated the performance of green beans (Phaseolus vulgaris L.) as affected by fruit setting hormones and time of application in Minna, Southern guinea savanna Nigeria. The treatments were three levels of fruit setting hormones (Control, Cytokinin and Beta Naphth Oxy-acetic Acid (BNOA)) and four periods of application (seed priming for 8 hours + application at vegetative and flowering stage, application at vegetative and flowering stage only, application at flowering stage only and application at two weeks interval throughout the experiment). These were factorially combined to give twelve treatments combinations which were arranged in a randomized complete block design with three replicates. Data were collected on growth, flowering and yield parameters. Data collected were subjected to analysis of variance using General Linear Model procedure of Minitab software. Differences between the means were separated using least significant difference (LSD) at 5% level of probability. The results revealed that seeds primed with cytokinin were the fastest to emerge while those primed with BNOA did not emerge. Plants that received BNOA at 2 weeks interval and plants that received Cytokinin both at vegetative + flowering stage had the longest vine, fattest stem and largest leaf area. Plants that received BNOA were the earliest to approach 50% flowering (33 days) compared to other treatments (34-40 days). Plants that received Cytokinin at two weeks interval throughout the experiment had the longest pod, fattest pod, heaviest fresh and dry pod weights as well as the highest number of pods per plant. Application of cytokinin at 2 weeks interval throughout the growth stages of green beans can therefore be recommended to improve the productivity of the crop.
