The study in relationship with endogenous adjustment of agroecosystems and security feeding to climate change and perturbation has been conducted to South-Kivu throughout an investigation by questionnaire near 422 chiefs of agricultural households in the global purpose to contribute to a lasting management of agroecosystems and the comprehension of dynamic functioning of exploitations of natural resources throughout the identification of strategies set by the agricultural household to fight against harmful effects of climate perturbation in their activities. The study has shown that in South-Kivu, adjustment strategies are especially reactive and their adoption by agroecosystems exploiters is very slow and in the government programs, the adjustment of the sector of the feeding production to climate change is not yet among priorities. This conducts to encourage political deciders, farmers and Scientists to set agroecological techniques and practices the systems of assurances to agricultural risks and installs the precocious alert system in each territory to warman inform agricultural on the evolution of environmental parameters.

The present study looked at the effects of planting date and spaces on growth and yield of soybean (Glycine max L. Merr) in soil and climatic conditions in Lubumbashi region. The trial was installed following a split plot design with three replicates. The main plots consisted of sowing dates (15th December, 30th December and 15th January) and the second plots included all seeding rates leading to a population of 125,000 plants per hectare (40 Cm x 20 cm was due to seed per hole; 40 cm x 40 cm with 2 seeds per hole and 60 cm x 40 cm with 3 seeds per hole). The results showed that late planting leads to slower growth and reduced yield of soybean. However, different plant densities adopted included similar effects in all the parameters observed. Planting soybean on the 15th December at a space of 40 cm x 20 cm x 3 seeds per hole would effectively increase soybean yield in the Lubumbashi region. The increase in performance would be desirable in order to fight against bad nutrition considering the scarcity of animal protein and the low- income populations.

Sustainability and economic efficiency in corn production could increase by the integrated weed management to a tolerable level. A study was conducted at the Kasapa farm during the 2013-2014 crop year to assess growth, grain yield of two improved varieties of maize (UNILU and Bukidi-Bukidi) and production economics Starting from two modes of weeding (manual weeding hoe and chemical weeding) and 4 weed management alternatives: {Weeding Manual (TO), 3l / ha atrazine (T1), 3l / ha acetochlor (T2), 6l / ha atrazine and acetochlor mixture (T3)}. The results revealed that the two varieties were similar height perspective of seedlings and yield. Six species have been recorded, but only two species (Setaria pumila and Cyperus rotundus) were resistant to their presence in all plots. Compared to weed management practices, performance culture has evolved as follows: T2> T3> T1> T0.Cependant an acceptable economic return was obtained with 3l / ha acetochlor. To intensify maize production in the study area, the mixture of acetochlor and atrazine is Discourage while adoption of acetochlor requires an extension on these modes.

This study checks the hypothesis which the organic amended contain components alternatives according to their mode of obtaining and conservation. Their use in agriculture efficiently contributes to resolve the problem of infertility of the soil. Samples of biowastes were analyzed at the laboratory to determine the composition in major fertilizers. Four doses of biowastes and three doses of fertilizers were applied only or in combination in a device completely randomized to three repetitions. The observations on the onion and spinach plants related to the height of plants, the number of sheets and the weight of the useful product and the results obtained were subjected to the analysis of the variance. It emerges from the physical characterization that the biowastes contain more 95% of organic matter. The chemical composition as well with it showed as these biod

The present work was undertaken to study the effects of planting date and spacing on growth and production of cowpea (Vigna unguiculata L. Walp.) in view to increase cowpea yield in Lubumbashi. The experiment was installed following a split splot device with 3 repetitions. The main plots consisted of 3 planting dates (15 December, 30 December and 15 January) and secondary plots, three spacing leading to a density of 125,000 plants per hectare (40 cm x 20 cm x 1 plant; 40 cm x 40 cm x 2 plants and 60 cm x 60 cm x 3 plants). Observations were made on growth and yield parameters. The results showed that late sowing leads to slower growth and lower yield. Sowing the third time results in a lower yield of 50% (500kg.ha-1) compared to planting at first date (1000 kg.ha-1). In addition, the higher yield was obtained with the second planting date (1300 kg.ha-1). The different spacings induced similar effects for all parameters observed. Sowing cowpea on December 30 and spacing of 60 cm x 40 cm x 3 plants would increase effectively cowpea yield in the city of Lubumbashi and its hinterland.

Two essays were carried out to evaluate the effect of different types of auxins on root formation and the influence of dark and culture substratum on tetraploid hybrid FHIA-01 proliferation (Musa spp. AAAB). The plant material consisted of tissue culture plantlets of FHIA -01 hybrid tetraploid banana (Musa AAAB). The trial, with a total of 10 replicates per treatment was carried out in each pot containing five explants. For both tests, a combination of two cytokinins was enriched in culture substratum. The results obtained show that regeneration was high in culture substratum with light than substratum without meta-methoxytopolin riboside (M2). The medium M2 to the light induced a higher number of the buds compared to medium dose reduced meta-methoxytopolin riboside (M1). Meanwhile, only explants inoculated on the medium M1 in the dark induced callus. The bud proliferation, induction of root, leaf and the broadcast callus induction are significantly influenced by the different substratum and photoperiod, increasing the explant size, the number of emerged leaves, roots and the number of the weight of explant with buds proliferated. Formulating specific culture media cultivars according to group (ABB or AAA) and the choice of culture conditions (light intensity) would avoid consecutive failures and low proliferation in in vitro culture.
