1.0 BACKGROUND OF THE STUDY
Tomato (cycospersicum esculentum) is one the most popular and widely grown vegetable in the world. The precise centre of origin and domestication of the presented cultivated tomato is uncertain purse glove (1968) point to the central and South America precisely at per Ecuadeor area as the region of origin. This view is not different from that of Anyanwu A.C, (1979who also considered tomato as being indigenous to Izeu and Ecuador in South America from where it spread out to other parts of the world. Tindal H.D 1983 investigated that the cultivated tomato originated in the slope of the Andes mountain of South America. The spread of ...view middle of the document...
Tomato can be eaten raw or cooked. Buds usage quantities are also used to produce soup, juice, etc. they are also used in the canning industries, green tomatoes are used for pickles and prescriles. The seeds which are extracted from pulp and residues contains 45% oil and the oil are used for salad dressing and in factories of margarine and soap. The residual press cell as stock feed and as fertilizers. World leading producers of tomato are soviet union, United States, Indiana, New Tersey and Alabema. Encyclopedia of science and technology 1982. In Nigeria, state that produce tomato in large quantities are Plateau, Oyo, Gombe and Benue State.
The total average under tomato is not known in Nigeria which creates difficulties to estimate the annual production of tomato in the country. The average yield depends upon certain production factors, amongst their appropriate and balance nutrient on Fertilizer application is one of the most important factors for obtaining economic yield.
1.2 STATEMENT OF THE PROBLEM
Tomato production in West Africa is relatively low in comparism with the world total output, but its demand is steadily increasing as a result of large quantities of tomato are imported into West Africa annually, in Nigeria imported 4,572 tons of tomato paste and this data shows that there is inadequate production of tomato with in the country despite the importance of tomato in the diet and economy of the nation. The production has been far below the needs of fast growing population of Nigeria. This has been attributed to local traditional methods of its cultivation yielding 3-4 tons/ha (Nigeria many West African State). The research effort is therefore to search for the best production (yield) in this area through identification of ideal levels of fertilizer that will enhance yield in tomato production, since fertilizers are very costly and scarce.
1.3 OBJECTIVES OF THE STUDY
The study has instituted the broad objective to determine the effect of different level of N.P.K 15:15:15 fertilizer on the growth and yield of tomato. However the specific objective established are as follows:-
i. To evaluate the performance of N.P.K 15:15:15 at different levels of application on tomato.
ii. To examine the growth and yield of tomatoes in response to N.P.K 15:15:15 fertilizer application.
iii. To determine the best yield result of tomato at the specific rate of fertilizer application.
iv. To assist the cultivars with the best economic management practice that result to optimum yield of tomato.
v. To enhance the quality of efficient production of tomatoes.
1.4 JUSTIFICATION OF THE STUDY
Tomato is one of the most widely grown crops around Yandev locality by the farmers for both consumption and commercial purpose. In essence, it is widely grown for commercial purpose in the state and the country in general. In view of the purpose of study established the following justification:
i) Assist in making valid fertilizer rate...
