EFFECT OF ORGANIC FERTILIZER AND METHOD OF TRAINING IN SOME OF THE YIELD CHARACTERS QUANTITATIVE THREE GENOTYPES OF TOMATO (Lycopersicon esculentum Mill( GROWN UNDER GREENHOUSE CONDITIONS

Research was carried out to evaluate the effects of individual and combined application of organic, NPK (15:15:15), organic plus NPK (15:15:15), fertilizers on the growth parameters of tomato (Lycopersicon esculentum. Mill) in the greenhouse condition of The Oke – Ogun Polytechnic, Saki (Derived savannah), Oyo State, Nigeria. Study was conducted in complete randomized design (CRD). Treatments were at four levels and replicated three times. The soil used was loamy sand. Results showed that the highest average number of leaves (140), number of roots (136), root girth (19.3 cm) and root length (40.8 cm) were achieved in organic plus NPK, highest average plant height (78.4 cm) and stem girth (7.6 cm) was achieved at 50 gm level of NPK (15:15:15) fertilizer treatment, while the highest average leaf area (45.6 cm2) was achieved at 50 gm level of organic fertilizer, the control values were far reduced compared to other levels of treatments. The analysis of variance indicated that organic fertilizer, organic plus NPK (15:15:15) fertilizers had significant (p ≤ 0.05) effects on number of roots, plant height, stem girth, root girth, leaf area, root length and number of leaves. NPK (15:15:15) fertilizer had significant (p ≤ 0.05) effect on number of leaves, plant height and leaf area and no significant (p ≤ 0.05) effects on number of roots, stem girth, root girth and root length, however, 50 gm level of treatment of organic fertilizer had distinct improved significant (p ≤ 0.05) effects on four (4) growth parameters; number of leaves, stem girth, root girth and root length when compared with other levels of treatments for NPK (15:15:15), organic plus NPK (15:15:15) fertilizers, therefore, 50 gm level of organic fertilizer could be applied for better production of Tomato (Lycopersicon esculentum. Mill) in a loamy sand soil.

Set Up

La baisse de la fertilité des sols due à la mauvaise gestion des terres et l’utilisation excessive des engrais chimiques a motivé le regain d’intérêt dans la recherche de fertilisants organiques respectant l’environnement pour un développement durable. Pour évaluer l’efficacité agronomique des litières de Jatropha sur la production de la tomate, une étude a été conduite en champs dans des pots de 20 cm de diamètre. Le dispositif expérimental est un bloc de Fischer randomisé avec un total de 64 pots (4 traitements x 4 répétitions x 4 unités expérimentales). Les résultats ont montré que les litières de Jatropha curcas et Jatropha gossypifolia ont amélioré la croissance et le développement (le diamètre et la ramification de la tige, le nombre de feuille et de fruits ainsi que la masse des fruits) de la tomate par rapport au témoin. La litière de Jatropha curcas a induit une large amélioration de la masse des fruits (33,09 g) par rapport aux autres traitements : le témoin (19,99 g), la litière de Jatropha gossypifolia (20,44 g) et l’engrais chimique (24,02 g). Pour une culture dont on aimerait avoir des gros fruits l’utilisation des fertilisants organiques à base des litières de Jatropha curcas pourrait être conseillée.Mots clés : Fertilisant organique, Litière, Jatropha curcas, Jatropha gossypifolia, Nord-Cameroun. English Title: Effect of organic fertilization based on leaf litter of Jatropha curcas L. and Jatropha gossypifolia L. on the tomato crop (Lycopersicon esculentum Mill.) in Guider (North Cameroon)The decline in soil fertility due to poor land management and excessive use of chemical fertilizers has induced new interest in the quest for environmentally friendly organic fertilizers for sustainable development. To assess the agronomic effectiveness of Jatropha litter on tomato production, a study was conducted in the field in pots of 20 cm in diameter. The experimental set-up is a randomized Fischer block with a total of 64 pots (4 treatments x 4 repetitions x 4 experimental units). The results showed that the litters of Jatropha curcas and Jatropha gossypifolia improved the growth and development (the diameter and branching of the stem, the number of leaves and fruits as well as the mass of the fruits) of the tomato compared to the witness. Jatropha curcas litter induced a large improvement in fruit mass (33.09 g) compared to other treatments: the control (19.99 g), Jatropha gossypifolia litter (20.44 g) and chemical fertilizer (24.02 g). For a crop from which we would like to have larger fruits, the use of organic fertilizers based on Jatropha curcas litter could be recommended.Keywords: Organic fertilizer, Litter, Jatropha curcas, Jatropha gossypifolia, North Cameroon.
