“…These ratios are indicative of the profitability of pineapple enterprise in the study area. Profitability of pineapple production appears to be low but is not in comparison with other fruit crops (Afolami & Ayinde 2001;Tijani et al 2010). The reasons for the low profit were shortage of improved planting materials, low level of production technology and high perishability of the crop, which led to low output price.…”

Pineapple is a delicious tropical fruit with a fine flavour and high nutritive value. It is one of the most important commercial fruit crops in the world. Despite its popularity, no proper data on the costs of its production in Nigeria are available. The study determines profitability and constraints of pineapple production in Osun State, Nigeria. Multistage sampling technique was used to obtain information from 50 respondents using purposive and random selection. Data collected were analysed using descriptive statistics and budgetary technique. Results indicated that majority of the farmers were males, aged 53.7 years on average and engaged full time in pineapple production. The modal level of farmer's education was primary. The average period of experience in pineapple farming was 13.5 years. The gross margin and net profits in Naira (Nigerian currency) were N182 725 and N162 045, respectively. The questionnaire in the study contained the most serious problems confronting pineapple farmers: limited availability of high quality planting materials, high fruit perishability, low fruit prices, low access to credits and plant diseases. Availability of high yielding pineapple varieties, establishment of cold storages to reduce fruit perishability, agricultural price support programmes, easier access to credit from formal sources and farmers' education were considered essential to improve productivity and profitability of pineapple production in Nigeria.

“…Also, its long duration to germination means that the risk of seeds damage is high due to prolonged exposure to adverse conditions such as cold and wet soil, and pests and diseases. Hybrids that are bred to adapt to hot/wet conditions, which is not a natural growing condition for tomato, is expected to perform better [10]. Thus, in ideal field conditions for tomato cultivation, Roma Vf can be germinated in situ.…”

“…This suggests that these hybrids (particularly AVTO9001) may have been bred for increased efficiency in accumulating, utilizing and transport of assimilates. Breeding plants for similar characteristics is a well-known practice [10].…”

“…Tomato grows best under good moisture conditions (not water logged), in temperatures that ranges between 25-27 o C [6], conditions that present diurnal temperatures of 25-27 o C in the day time and 18 o C at night time. Heavy rains and poor ventilation can also reduce tomato productivity by inhibiting the activity of agents of pollination, reducing the population of the agents of pollination and increasing flower bud and fruits fall [10]. Thus growing tomato under hot conditions can be an adverse environmental condition or stress.…”

“…The hot and wet season is the longest season in many high rainfall humid tropical areas such as Niger Delta in Nigeria. In Nigeria therefore, commercial tomato production is restricted to the North of the country with a savannah agroecology and a few Southern states with moist savannah agroecology [8].With a population of 160 million people and a production of 1,701,000 tones of tomato per annum Nigeria produces only 5% of what is produced by China, and 12% of that produced in the United States of America [9], and Nigeria's demand for fresh tomato surpasses its supply particularly during offseason [10].Generally, the constraints to tomato production in Nigeria include the restriction of tomato production to a particular season, resulting in periods of abundance and scarcity, which in turn leads to high fresh fruit price, and the cultivation of exotic cultivars that are not well adapted to local conditions [7]. Other constraints are poor seed quality, misuse of fertilizer, inadequate land, poor transport system, and pest and disease problems, particularly during the rainy season [11].…”

Tomato (Lycopersicum esculentum Mill.) is a commonly cultivated vegetable crop; however, there is a dearth of information on germination and vegetative growth of tomato cultivars under the hot and wet humid tropical conditions of the Niger Delta in Nigeria. Although several hybrids exist, there are no known cultivars selected for cultivation under the Niger Delta conditions. The objectives of this study were to evaluate the germination and vegetative growth of five tomato cultivars under hot and wet conditions, and to identify potentially suitable cultivar(s) for the Niger Delta. The tomato cultivars tested included a high-performing non-hybrid cultivar common to northern Nigeria (Roma Vf), hybrids bred for hot and wet environment (AVTO9803 and AVTO9001) and hybrids bred for cool/dry environment (AVTO1001 and AVTO1006). Germination tests were conducted and the cultivars were grown under two conditions during the rainy season: in the open field under direct rain, and in a glasshouse with regular watering to field capacity. Results show that Roma Vf had the poorest percent germination (19% in cold test) by 6 days after sowing, while the best performing cultivars in terms of seed quality were AVTO9803 and AVTO9001. In both field and glasshouse environments, Roma Vf grew significantly taller, with more nodes, high leaf numbers, leaves and greater leaf lengths than the exotic cultivars (with the exception of AVTO9001 and sometimes AVTO9803). The cultivar AVTO9803 performed best under the extremely hot conditions (≥35°C) in the glasshouse than on the field. This suggests that the two hybrids (AVTO9803 and AVTO9001) and Roma Vf are potentially cultivable under the hot/wet conditions, but Roma Vf would require extra care due to its poor germination rates.
