The experiment was conducted in the Department of Horticultural Technology, Enugu State Polytechnic, Iwollo, Enugu state, Nigeria to determine the impact of hydro-priming duration on seed germination and emergence indices of sweet basil (Ocimum basilicum) in August, 2018. The treatments were 6, 12, 18, and 24 hours of hydropriming. The control treatment was left un-primed. Twenty seeds from each treatment were plated in Petri dish which contained two layers of filter papers that were wetted with 10 ml of distilled water and was used for the germination studies. Twenty seeds from each of the treatment were sown in 2 kg nursery medium (poly pot) with nursery mixture of soil, well cured poultry manure and sand in the ratio of 3:2:1, respectively and was used for the emergence studies. The experiment was laid in completely randomized design with three replications. Data on germination and emergence indices were collected and analyzed using analysis of variance (ANOVA). The treatment means that were significant were separated using least significant difference at 0.05 probability level. The results showed that hydro-priming significantly (p<0.05) increased germination percentage, coefficient of velocity of germination, coefficient of uniformity of germination, emergence percentage and coefficient of velocity of emergence with 18 hour having superior values and the least values were in control. Hydro-priming also significantly decreased mean germination time, mean emergence time, days to 50% germination and days to 50% emergence with the least values obtained in 18 hours and the highest values were in control. It can be concluded that hydro-priming significantly improved germination and emergence of sweet basil (O. basilicum). The optimal hydro-priming duration for sweet basil (O. basilicum) was 18 hours, which enhanced seed germination and emergence percentage, ensured early germination and seedling emergence, and increased uniformity of emergence.
A b s t r a c t A r t i c l e I n f oField assessment of performance of four cucumber (Cucumis sativus L.) cultivars namely, Ashely, Marketer, Super-marketer and Pointsett-76 in Iwollo, South-eastern, Nigeria was carried out at the Teaching and Research farm of the Department of Horticultural Technology, Enugu State Polytechnic, Iwollo. The four cultivars made up the treatments. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. Data on days to 50% emergence, emergence percentage, vine length, number of leaves per plant, number of branches per plant, leaf area index, days to first female flower initiation, number of fruits per plant, weight of a fresh fruit, fresh fruit weight per plant and fresh fruit yield per hectare were collected and analysed using Analysis of variance (ANOVA) for Randomized Complete Block Design (RCBD). The treatment means were separated using least significant difference at 5% probability level. The results showed that there were significant differences (p<0.05) among the cultivars at 45 days after planting in vine length, number of leaves per plant, number of branches per plant and leaf area index with Pointsett-76 having superior values. Pointsett-76 cultivar was also significantly (p<0.05) superior to other cultivars as regard to days to first female flower initiation, number of fruits per plant, weight of a fresh fruit, fresh fruit weight per plant and in fresh fruit yield per hectare. Pointsett-76 cultivar therefore performed better than the other three varieties in the study area and could be recommended to farmers for improved production of cucumber.
A field experiment was conducted at the Teaching and Research Farm of Enugu state polytechnic, Iwollo, Southeastern Nigeria in 2020 to evaluate the profitability of the use of poultry manure for cucumber production in the area. The study was carried out in a randomized complete block design (RCBD) with four replications. The treatment comprised different rates of poultry manure viz; 0 (control), 5, 10, 15 and 20 t ha-1. The growth and yield parameters investigated were vine length, number of branches per plant, number of leaves per plant, leaf area index, number of fruits per plant, fruit yield per plant and fruit yield per hectare. The data collected on growth and yield parameters were subjected to analysis of variance (ANOVA) and treatment means were separated using Fisher's least significant difference (F-LSD) at 5% level of probability. Gross margin (GM) as well Return on Investment (RoI) was calculated to determine the profitability. The results showed that poultry manure significantly (p<0.05) induced higher vine length, number of branches per plant, number of leaves per plant, leave area index, number of fruits per plant, fruit yield per plant and fruit yield per hectare compared to control (0 t/ha) with optimum values obtained in 20 t ha-1. The profitability of the use of poultry manure increased with increase in the rate of poultry manure. The highest gross margin (N 3,233,860) was obtained from 20 t ha-1 of poultry manure followed by 15 t ha-1 (N 2,021,020), 10 t ha-1 (N 1,381,748), 5 t ha-1 (N 588,300) and 0 t ha-1(N14,660). Similarly, the highest RoI was obtained in 20 t ha-1 of poultry manure (325.95%) followed by 15 t ha-1 (237.49%); 10 t ha-1 (185%); 5 t ha-1 (93%) and the lowest was in 0 t ha-1 (2.76%). It could be concluded from the study that the use of poultry manure for cucumber production in Iwollo is profitable and most profitable when 20 t ha-1 is used.
