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.

Fusarium wilt (Fusarium oxysporum f. sp. lycopersici), root-knot nematodes (Meloidogyne spp.), and purple nutsedge (Cyperus rotundus L.) are among the most damaging soilborne pests for tomato (Lycopersicon esculentum Mill.) production in the southeastern United States. Allyl isothiocyanate (allyl ITC) was evaluated as a potential fumigant alternative for control of soilborne pathogens, nematodes, and weeds. Shank- or drip-injected allyl ITC at rates ranging from 221 to 367 kg ha−1 exhibited excellent performance, reducing the recovery of total F. oxysporum from treated soils. Shank- or drip-injected allyl ITC at 367 kg ha−1 provided equivalent control of C. rotundus compared with 1,3-dichloropropene + chloropicrin and metam potassium, respectively. Totally impermeable film (TIF) did not further reduce the recovery of F. oxysporum and various nematodes from soil treated with allyl ITC compared with virtually impermeable film (VIF). However, TIF mulch significantly improved C. rotundus control versus shank- or drip-injected allyl ITC treatments under VIF mulch. Overall, allyl ITC is an effective methyl bromide alternative against F. oxysporum, C. rotundus, and plant-parasitic nematodes Criconemella spp. and Hoplolaimus spp. in plasticulture tomato production.

ABSTRACT ECONOMIC ANALYSIS OF UTILIZATION OF MIX ORGANIC FERTILIZER FROM CATTLE FECES ON TOMATO (Lycopersicum esculentum Mill. L.) FARM (Case study at Tondegesan Two Village Kawangkoan District of Minahasa Regency) The objectives of this study were to analyze cost, income, production and factors affecting tomato farm using organic fertilizer from cattle feces at Tondegesan Two village, Kawangkoan district of Minahasa regency.        Respondents were defined by census method. Data were collected by interviewing mechanisms, direct observation and available documents. Data were based on primer data including land area, workers, salary, total seed, seed prize, total fertilizer applied, fertilizer price, tomato production per planting period, tomato selling price, production cost, income as well as general condition of farmer.  Secondary data were based on the reference (library and internet) or other institutions related with this study such as animal population and tomato farmers. Data were analyzed by different test using t test on pair samples. Results showed that costs of tomato farm using organic fertilizer from cattle feces were IDR 32,936,915 less than costs of tomato farm using non-organic fertilizer of IDR 38,659,431. On the other hand, farmer incomes using organic fertilizer from cattle feces were IDR 43,653,085 more than farmer income using non-organic fertilizer of IDR 34,938,069. The productions of tomato farm using organic fertilizer from cattle feces were 30,636 kg more than production of tomato farm using non-organic fertilizer of 29,439 kg. Using regression analysis of production function by cobb douglass method for factors affecting tomato farm indicated that the variables of workers and seed total affected significantly tomato production with probability of 0.005, while total organic and non-organic fertilizers did not affect tomato production. Therefore, it can be concluded that utilization of the organic fertilizer increased farmers’ income of the tomato farm.   Key words:Cattle feces organic fertilizer, tomato production, cost, income.

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.

The Moment

The use of organic fertilizers in agricultural production can not only increase soil fertility but also at the same time improve soil quality. Organic fertilizer is a unique product because it can improve physical properties, chemical, and biological soil as plant growth media. These characteristics bring the organic fertilizers into a valuable product that can be used in a variety of use. Today in Indonesia, there are so many outstanding varieties of organic fertilizer products either refined or imported products. Monitoring of the quality and feasibility of organic fertilizer materials is needed, so they will not harm the farmers as consumers. Each country develops criteria standard of organic fertilizer valuing each country's interest. United States, Canada, Australia and Europe use different compost quality criteria tailored to the needs and environmental rules that apply. So far in Indonesia rules used in determining quality is Permentan No. 02/Pert/HK.060/2/2006 which was then updated with Permentan No.28/PERMENTAN/OT.140/2/2009 on Organic Fertilizers and Soil Ameliorant. Basically, the appraisal made on the maturity and quality of organic fertilizers is based on observation of physical, chemical, and biological parameters. Review of the criteria used in the Regulation of the Minister of Agriculture was necessary in considering the criteria used which are very harmful to consumers, such as if it is satated that C-organic content is approximately 12%, which is low, it means that there might exist some follow-up materials such as glass, plastic in the fertilizer about 2%. If the rules are maintained, it will be very detrimental to Indonesia because of invasion from over seas. Import organic fertilizers would be siege to Indonesian farmers. Permentan No.28/PERMENTAN/SR.130/5/2009 has also set up institutions in charge of monitoring the quality of organic fertilizers. However, the quality control must be carried out. It is not only at the level of the end product, but it must also begin from the moment of the production process by establishing a supervisory agency competent. Since organic fertilizers can be produced by large industries, small and medium-scale farmers, the level of supervision is needed with different approaches.

High Tunnels

Interest in unheated plastic film-covered high tunnels to extend the growing season of high-value fruits and vegetables is growing rapidly, but sustainable soil management in intensively managed high tunnels is challenging. Yields, fruit quality, and soil quality in transition organic and conventional tomato were measured over the course of three growing seasons. Nitrogen (N) was applied at the rate of 112, 168, and 224 kg total N/ha in the form of chicken manure compost to the organic treatments and a polymer-coated slow-release urea fertilizer in the conventional treatments. Marketable yield of organically grown tomatoes was lower in Year 1 but equaled conventional tomatoes in Years 2 and 3. Soil quality as measured by total carbon (C) and N and microbial activity was significantly greater in organic tomato production at the end of the study. Significant phosphorus (P) and potassium (K) applied with the composted manure resulted in high soil P and K levels in organically managed high tunnels after just 3 years of application. Although compost is the most economical organic fertilizer and results in significant benefits in soil quality during the transition phase to organic production, a maintenance fertility plan is needed once available soil P reaches adequate to high levels. Combinations of compost and high N, low P organic fertilizers are needed for optimum maintenance fertility strategy for organic tunnel house production.

The City

In general, coastal areas have the physical and chemical properties of lessfertile land with an extreme dry climate, so that only a few plants that can live,including Jatropha curcas L. To enhance fertility and improve soil physicalproperties, need the addition of organic fertilizer. Source of compost canbe derived from a variety of wastes, including household waste and landfill.Quality compost landfill taken from Piyungan, Yogyakarta, has a high content of organic C, pH neutral, low N concentration, with the ratio C/N is very high. But compost landfill has an obstacle in the form of heavy metal containing high Cu and Pb. To prevent accumulation heavy metals into plant tissue or clean up heavy metals from the soil it was attempted by phytoremediation using jatropha plantation and bio-fertilizer that contains bacteria Azotobacter sp and Pseudomonas sp.From the research results can be informed that: (1) The city compost and biological fertilizers, can increase soil fertility with increasing nutrient content in soil. (2) Biofertilizers could inhibit the accumulation of copper (Cu) and lead (Pb) into Jatropha curcas L., (3)Jatropha plant can be classified as phytoremediation plants, because it can absorption heavy metals into leaf tissue.Key words: landfill compost , bio fertilizer, jatropha plants, heavy metals
