Objectifs : Cette étude se veut de produire et de déterminer la valeur fertilisante du vermicompost, et mesurer les effets de ce vermicompost sur la croissance et le rendement du maïs. Méthodologie et résultats : Les travaux ont d’abord consisté à élaborer un compost d’ordures ménagères puis son vermicompost associé par inoculation du ver de terre Eudrilus eugeniae (Kinb.), et ensuite à évaluer leurs effets sur la production du maïs à travers un essai conduit en milieu naturel au sein de l’Université Jean Lorougnon Guedé Daloa. Les traitements sont composés d’un témoin constitué d’un sol de jachère, d’un compost d’ordures ménagères associées aux balles de riz et du vermicompost correspondant. Les résultats ont révélé que le vermicompost a les teneurs les plus importantes en N, P et K, mais les plus faibles concentrations en Cu, Zn et Pb. Les plants de maïs croissent mieux sur le vermicompost par comparaison au compost et au témoin. De plus, le traitement de vermicompost a produit la biomasse racinaire (45,625 ± 1,812 kg.ha-1), le nombre de grains par plant (391,68 ± 17,20 kg.ha-1) et la biomasse totale des grains de maïs (2608,969 ± 50,914 kg.ha-1) les plus élevés. Conclusions et application des résultats : Les travaux ont révélé l’importance de l’espèce Eudrilus eugeniae dans la formation d’un compost de bonne qualité chimique. Les paysans peuvent utiliser le vermicompost d’ordures ménagères associées aux balles de riz pour améliorer le rendement des cultures de maïs. Mots clés : Vermicompost d’ordures ménagères, Balles de riz, maïs, croissance, rendement. ABSTRACT Objectives: This study aims to produce and determine the fertilizing value of vermicompost, and to measure the effects of this vermicompost on the growth and yield of corn. Methods and results: The work consisted first of all in developing a household waste compost then its associated vermicompost by inoculation of the earthworm Eudrilus eugeniae (Kinb.), and then in evaluating their effects on the production of maize through a trial conducted in the natural environment in Jean Lorougnon Guedé University of Daloa. The treatments consisted of a control consisting of fallow soil, household waste compost associated with rice husks and the corresponding vermicompost. The results revealed that vermicompost has the highest levels of N, P and K, but the lowest concentrations of Cu, Zn Guei et al., J. Appl. Biosci. 2020 Effets du vermicompost à base d’ordures ménagères associées aux balles de riz sur les paramètres agronomiques du maïs (Zea mays L.) 15863 and Pb. Corn plants grow better on vermicompost compared to compost and control. In addition, the vermicompost treatment produced root biomass (45.625 ± 1.812 kg.ha-1), the number of grains per plant (391.68 ± 17.20 kg.ha-1) and the total biomass of grain (2608.969 ± 50.914 kg.ha-1) the highest. Conclusion and application of findings: The work revealed the importance of the species Eudrilus eugeniae in the formation of a compost of good chemical quality. Farmers can use household vermicompost associated with rice hulls to improve the yield of maize crops. Keywords: Household waste vermicompost, rice husks, maize, growth, yield.

A study entitled The Effect of Giving Solids Decanter and the Number of Perforated Planting Seeds on Growth and Yield of Corn Plants (Zea Mays L) in Ultisol Soil. This research was conducted for four months and was carried out in the Galuh Merindu 1 residential land and the Biology Laboratory of the Faculty of Agriculture, University of Lambungmangkurat. This study uses an environmental design in the form of a Completely Randomized Design using the interaction of two experimental factors, namely the dose of a solid decanter and the number of seeds per planting hole, which consists of seven treatments, namely: S0 (Control), S1 (10 ton/ha decanter solid), S2 (20 ton/ha decanter solid), S3 (30 ton/ha decanter solid), J1 (1 corn seed varieties BISI 18), J2 (2 corn seed varieties BISI 18). J3 ( 3 corn seed varieties BISI 18). Repeated three times so that there are 36 units of experiments, and from each unit of experiment consists of two polybags so that there are 72 plant polybags. Observations were made in the form of: plant height, number of leaves, plant wet weight, plant dry weight, length of crop cobs, diameter of planting cobs, number of row of perongkol seeds, number of seeds per row of cob, weight of 100 dried shelled seeds, dried shelled yield. The results of this study showed the best number of seeds treated at 1 seed per planting hole (J1), the best solid decanter treatment occurred at 30 tons / ha (S3) treatment and the best interaction was on the treatment of 1 seed per planting hole with 30 tons / ha Solid Decanter (J1S3).

A glass house study was conducted to evaluate the contribution of indigenous arbuscular mycorrhiza fungi (AMF) in improving maize yield grown on sandy loam of Northern Lombok. The package of organic fertilizers treatments were tested including: without inoculation of mycorrhiza, inoculation mycorrhiza and no added inorganic fertilizers, inoculation of mycorrhiza with cattle manure added, inoculation of mycorrhiza with rock phosphate added and inoculation mycorrhiza with inorganic fertilizers. The treatments were arranged using a Completely Randomized Design with four replications. The results of the study show that the inoculation of AMF significantly increased soil concentration of N, available-P, K and organic-C by 37.39%, 60.79%, 66.66% and 110.15% respectively observed at 60 days after sowing (DAS). The similar trend was also found at 100 DAS, where those nutrients increased by 21.48%, 69%, 43.93% and 37.07%, respectively compared to control. The improving of soil fertility status was also reflected by nutrients uptake (i.e. N, P, K, Ca) as well as growth and yield of maize. N, P, K and Ca uptake increased by 1,608%, 1,121%, 533% and 534%, respectively. Roots and top dry biomass at 60 DAS increased by 718.40% and 337.67%, respectively. The trend increased of the biomass was followed by observation at 100 DAS. Yield components including cobs, grain and weight of 100 grains increased by 313.60%, 411.84% and 137.54%, respectively. In addition, the inoculation of AM with F2 contributed significantly to the spore numbers and root infection.[How to Cite : Astiko W, IR Sastrahidayat, S Djauhari, and A Muhibuddin. 2013.

The aim of this work was to evaluate the attenuating effect of the nitric oxide donor (sodium nitroprusside-NPS) on the ecophysiological responses of corn plants (Zea mays L.) submitted to copper toxicity. The corn seeds of the K9606 VIP3 variety were soaked for 48 hours in Germitest with solution containing treatment with sodium nitroprusside Na2 [Fe (CN) 5 NO] 2H2O (0, 200 and 300µM), sodium ferrocyanide Na4Fe (CN) 6 ( 300, 100 and 0 µM) respectively and deionized water (control), sown in buckets with 15 kg of soil incubated for 50 days containing copper concentrations CuSO4.5H2O (0, 60 and 200 mg kg-1). The design consisted of randomized blocks with 12 treatments and 4 repetitions, making a total of 48 plants. in ecophysiological variables: height, leaf area and number of leaves, stem diameter increased by 32, 66% and 11.29% in the treatments with 60 mg kg-1 of copper and 200 mg kg-1 of copper, respectively. There was no effect of treatments on the chlorophyll content measured by the SPAD index and gas exchange. The chlorophyll a fluorescence variables indicate that the concentration of 200 mg kg-1 of copper caused damage to the structure of the PS II reaction center complexes and indicate a slightly protective effect of nitric oxide-NO present in sodium nitroprusside and cyanide present in sodium ferrocyanide, reflecting a smooth functioning of the maximum activity of photosystem II and the electron transport chain.
