Results showed significant differences in the number of leaves produced per plant, leaf area (cm 2 ), bulb diameter and bulb yield. A mean of 10 leaves/plant was produced when plants were spaced at 30.5cm x 15.2cm (215,054 plants/ha). The application of manure at 22.40 ton/ha gave mean of 11 leaves/plant. Leaf area was affected more by manuring at 22.40 tons/ha (65.26cm 2 ) than by plant population density. Bulb diameter was greatest (8.18cm) at the highest manure application of 22.40 ton/ha than at the lowest population density of 215,000 with a mean bulb diameter of 7.18cm. Total bulb yield (9.55 ton/ha) was influenced more by manure application at 22.40 ton/ha than by plant density. The implication of the findings is highlighted for successful onion production.

Weights of both fresh and dry shoot and root increased with plant age. Fresh weight of tender shoot, comprising the crisp leaf and soft stem portions located within the upper half of the plant height, was highest at 7 th WAS when it constituted 61% of fresh total shoot weight and 50% of plant fresh weight, and lowest by 16th WAS. Phosphorus and protein contents of the shoot declined as from the 7 th -10 th WAS, while shoot crude fibre increased throughout the plant growth period, building up more steeply after the 10th WAS. Stem calcium increased from 0.3%, at 4 WAS to 0.7% by week 13, and in the leaf from 0.25% at 4 WAS to a peak of about 0.35% at 10 WAS. The nutrient profile and tissue hardening pattern in the plant shoot implied that the vegetable would best be harvested around the 7 th WAS when its tender shoot would constitute maximum proportion, about 61%, of the total plant shoot weight, and metabolites, such as P and protein, abound most.

Different indigenous ripening technologies were in use. However, the most commonly used one in combination with African bush mango fruits ( Irvingia species) and polythene bags. The use of the indigenous ripening technologies helped the women to generate quick and constant relatively high income (X = N7,375 per month) which they used in purchasing more ripening facilities, more bunches of banana and plantain, essential household materials, etc. Nigerian Journal of Horticultural Science Vol. 9 2005: 96-101","PeriodicalId":185766,"journal":{"name":"Nigerian Journal of Horticultural Science","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133093614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seeds obtained from four pods of various sizes were sorted into five weight classes namely: W 1 (= 11g), W 2 (12-16g), W3 (17-21g), W 4 (22-26g) and (W 5 = 27g). Seedlings were first raised in a nursery and subsequently transplanted into the field. Whole pod weight was positively and significantly correlated with both total weight of seeds and empty pod weight (r 2 = 0.981 and 0.972 respectively) but seed quality could not be ascertained from total seed weight. Number of seeds per pod showed no significant correlations with pod characteristics such as weight, length, circumference and diameter. Seeds in weight class W 1 showed no emergence.

Four treatments namely; wood ash, guano, NPK and no fertilizer were laid out in a randomized complete block design with four replications. The result indicated that NPK fertilizer source had the highest bulb yield of 27.43t / ha and the highest net farm income of #626,600 t / ha, even though there was no significant difference. In another development, 20 randomly selected onion bulbs from each of these fertilizer sources were kept in three storage containers (open air with no container, black polythene bag and yellow polythene bag). The result indicated that NPK fertilizer source had the earliest and fastest deterioration rate as well as highest post harvest deterioration of 70 % while wood ash had the least and slowest deterioration rate and eventually the lowest post harvest deterioration of 10 %. It was also observed that black polythene bag container gave the highest post harvest deterioration of 50 % while open air (no container) gave the lowest post harvest deterioration of 25 %.
