Organic Cowpea “Vigna unguiculatea” Production by Smart Agritechnique of Organic Fertilizers Mixture ”OFM” and Vermitea Levels and Beneficial Microbes “BM”

Abstract

Positive response of cowpea to three levels (4, 6 and 8 t/fed.) of MOF "the mixture of 25% vermicompost+ 25% chicken manure+25% cow dump+25% plant composted" alone and in combination with beneficial microbes B.M. (the mixture of Azotobacter, Bacillus megatherium and Bacillus circulance) and three times of vermitea (VTS3) were adding (3 times on soil drench) were studied. Two field experiments were carried out at a private farm El Amryia, Egypt in two different sites. Experimental field was laid out with 13 treatments in RCBD with three replicates. On results, T13=MOF (8T/fed.)+B.M.+VTS3 gave the highest mean values of plant height (281.5cm), No. of branches (12.7), No. of pods/plant (37.6), total chlorophyll (60.25 SPAD) in leaves, pod weight (141.0 g/plant) and total pod yield (2924.704 kg/fed) as an average of both sites. The lowest means values at T1 "the control" were (81.6 cm, 2.8, 10.6, 16.8 SPAD, 39.3 g/plant and 815.555 kg/fed as an average of both sites, respectively). As well as; T13 lead to significant increases in grain quality of (N, P and K % and proteins %) were (4.7,0.5,0.9 % and 29.8%, respectively) compared to T1 (1.0, 0.11, 0.21and 6.7%, respectively). While T13 was caused significantly increases in mean values by the mixture of bio-organic fertilizers and bio-pesticides provided best results in vegetative growth, total pod yield and grain quality more than T1 in poor nutrients soil. Organic cowpea was produced by bio-organic fertilizers "MOF+B.M." and vermitea "VTS" really "chemicals free", health protection, cost lowest and environmental friendly.

Response of Two Potato Cultivars to Organic Fertilization and Potassium Foliar Application

“…In this respect, addition of animal compost significantly recorded the higher values of average fruit weight and total yield than the plant compost, while number of fruit recorded no significant effect. These results are in concurrence with (Abou El Goud, 2020;Djaman et al, 2021) they observed that the organic fertilizers are valuable for plants because of their beneficial impact on the chemical, physical, and microbial traits of the soil, also they found that animal compost produced in root zone high amount of IAA which in turns, reciprocally growth and increase plant production. Besides that, they focused on the organic agricultural production in Egypt in order to avoid plant and environmental pollution with various elements and to diminish the utilization of chemical fertilizers (Shaheen et al 2018;Djaman et al 2021).…”

“…It was found that addition of animal compost increased significantly the nutation values in comparing with plant compost. The consistent release of the nutrients from animal compost may have resulted that, they have been taken up mainly for the most part of available forms which probably caused accumulations of nutrients in the plants tissues (Abou El Goud, 2020 andDjaman et al 2021).…”

Study of Reducing Chemical Fertilizers and Enhancing by Organic and Biological Fertilizers for Cowpea Crop

“…The reason for the superiority of fertilizer treatments in increasing the number of pods per plant due to the role of integration between the components of BioHealth in regulating the vital activities inside the plant that are related to growth and cell division, which encourages the formation of good vegetative growth, which causes an increase of efficiency of vegetative growth and increase in the average number of branches and leaves per plant , it reflected on the seed yield [13,14] who emphasized the role of integration between biological and chemical fertilizers in improving the vegetative growth characteristics of cowpea plants and increasing the yield, in addition to the role of bio-fertilizers in the increase of flowering and pod formation [5,15] when biological fertilizers are used with half of the chemical fertilizers. in another interpretation, the increase in the characteristic of the number of pods in the plant is attributed to the role of the biological material in releasing nutrients and improving the physical and biological properties of the soil, which is positively reflected in the absorption of nutrients from the plant [16], and the role of bio-fertilizers in increasing plant susceptibility to dry matter accumulation and protein synthesis [17,18].
