This article aims to examine the effect of phosphate solubilizing bacteria (PSB) on the growth and yield of G3 seeds of potato (solanum tuberosum L.) varieties of medians. The experiment was conducted in the experimental garden of The Faculty of Agriculture of Winaya Mukti University Tanjungsari, Sumedang with a height of 850 meters above sea level with the order of land Andisol. Time trials are conducted from May to August 2019. The design used is a simple RandomIzed Group Design consisting of five types of phosphate Solubilizing bacteria, namely without PSB, Pseudacidovorax intermedius, Agrobacterium fabrum, Agrobacterium tumefaciens, Serratia nematodiphila and repeated five times each. The results of the experiment showed that the administration of this type of PSB was able to increase the height of the plant and the number of leaves at the age of 28 DAP and 42 DAP and give the result of the number of potatoes and the weight of the perpetak tubers on the potato crop of the medians varieties better.

Le bas niveau de la fertilité des sols à Kabinda et la rareté des engrais chimiques sur le marché orientent les agriculteurs à recourir à une fertilisation palliative et durable. Cette étude a été réalisée dans le but d’évaluer l’effet des amendements organiques sur la croissance et le rendement de la pomme de terre. L’essai était installé suivant un dispositif en blocs complets randomisés. Les traitements en cinq répétitions ont été constitués d’un témoin (T0), de la bouse de vache (T1), de cendres (T2) et de la biomasse fraiche de Entada abyssinica (T3). Les observations ont porté sur les paramètres de croissance et de rendement et l’analyse de la variance (ANOVA) a été appliquée pour la comparaison. Les résultats obtenus renseignent que la pomme de terre se comporte positivement sous effet d’amendements (P<0.05) comparativement au sol non amendé. Le plus grand nombre de feuilles est démarqué nettement au traitement à base des cendres avec 4 feuilles contre 2 feuilles pour le témoin. L’apport de la cendre à la dose de 10 kg/ha sur la culture de la pomme de terre a augmenté le rendement de 1 t/ha par rapport au sol non amendé. L’utilisation de ces amendements dans une région comme Kabinda contribuerait au développement de l’agriculture en luttant contre l’insécurité alimentaire et la pauvreté. Ainsi donc, L’utilisation de la cendre est recommandable pour la production de la pomme de terre vu ses effets sur la culture et sa disponibilité dans la ville de Kabinda.Mots clés : Fertilité, engrais chimiques, production, Solanum tuberosum , Kabinda. English Title: Effect of organic amendments on growth and yield of potato (Solanum tuberosum L.) on soil degraded in Kabinda area, Democratic Republic of CongoThe low level of soil fertility in Kabinda and the scarcity of chemical fetilizers on the market guide farmers to seel palliative and sustainable fertilization. This study was carried out in order to assess the effect of organic amendments on the growth and potato yield. The trial was installed using a ramdomized complete block system. Five Treatments in five repetitions, consisted of a witness (T0), cow dung (T1), ash (T2) and Entada abyssinica fresh biomass (T3). Observations focused on growth and yield parameters and analysis of variance (ANOVA) at the 5% threshold was applied for comparison betwen treatments. The results obtained indicate that the potato behaves positively under the effect of amendments (P<0.05) compared to unamended soil. The greatest leaves number is clearly demarcated in the ash based treatment with 4 leaves versus 2 leaves for the witness treatment. The addition of ash to the potato crop increased the yield by 1 t/ha compared to the unamended soil. The use of ash is recommendable for the production of potato in the city of Kabinda.Keywords : Fertility, chemical fertilizers, production, Solanum tuberosum, Kabinda

The study aimed to determine the effect of the combination of city waste compost and cattle manure on the growth and yield of pakcoy plants (Brassica rapa, L. Chinensis) in Aluvial, Indramayu Regency. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Wiralodra University, Indramayu Regency from March to August 2018. This study used Factorial Pattern Randomized Block Design with two factors. The first factor is city waste compost and the second factor is cattle manure with 4 levels: 0%, 3.0%, 6.0%, and 9.0%, repeated twice. The results showed that there was an independent influence between city waste compost and cattle manure on plant height and number of leaves. The best combination to increase the feasibility weight of pakcoy consumption is by giving city waste compost 9.0% (S4) and cattle manure 6.0% (K3).

AbstractIn this work, the effects of co-inoculation between an arbuscular mycorrhizal fungus (AMF) and a phosphate solubilizing bacteria (PSB) to promote the growth and production of sunchoke under field condition were investigated during 2016 and 2017. Four treatments were set up as follows: plants without inoculation, with AMF inoculation, with PSB inoculation and with co-inoculation of PSB and AMF. The results showed the presence of PSB and AMF colonization at the harvest stage in both years. This suggested the survival of PSB and successful AMF colonization throughout the experiments. According to correlation analysis, PSB positively affected AMF spore density and colonization rate. Also, both AMF and PSB positively correlated with growth and production of sunchoke. Co-inoculation could enhance various plant parameters. However, better results in 2016 were found in co-inoculation treatment, while AMF inoculation performed the best in 2017. All of these results suggested that our AMF and PSB could effectively promote growth and production of sunchoke under field conditions. Such effects were varied due to different environmental conditions each year. Note that this is the first study showing successful co-inoculation of AMF and PSB for promoting growth and yield of sunchoke in the real cultivation fields.
