أثر إستخدام الأسمدة الحيوية على إنتاج بعض محاصيل الخضر في الأراضي الجديدة

Abstract EN

The research aimed mainly at measuring the effect of using biofertilizers on the production of some summer vegetable crops grown in the new lands and compare it to the traditional agriculture method, this can be achieved through recognition the most important factors affecting the production of vegetable crops the research topic for the tow patterns of agriculture, and review of the structure of the production costs of bio and traditional vegetable crops for comparison, and estimation of some indicators of productive and economic efficiency for the production of vegetable crops the research topic for the tow patterns of agriculture.

In achieving its objectives, the research relied on the use of descriptive and quantitative economic analysis methods such as the use of the regression stepwise method in estimating production functions, and estimate some indicators of productive and economic efficiency by relying on field data for a random sample of summer vegetable crops producers and represented by (tomatoes, zucchini and pepper) in the Nubaria region for the agricultural season 2018/2019 they numbered 150 farmers, of whom 50 were farmers of each crop divided into 25 farmers with traditional agriculture, 25 farmers with bio agriculture .

And estimating the productive functions of the tomato, zucchini and pepper crop, in the style of traditional agriculture in the sample of the field study, It has been shown that the total productive elasticity of the productive elements having a positive and moral effect on the production quantity and it amounted to about 1.344, 1.117 and 0.879, respectively.

this means that the production of tomato and zucchini it is in the stage of increasing return to capacity, while the production of pepper is in the stage of decreasing return to capacity.

And estimating the productive functions of the tomato, zucchini and pepper crop in in the style of bio agriculture in the sample of the field study, It has been shown that the total productive elasticity of the productive elements having a positive and moral effect on the production quantity and it amounted to about 0.896, 0.791, and 0.912, respectively, which means that production in the stage of decreasing return to capacity.

The results also showed the superiority of the economic efficiency indicators for vegetable crops grown under bio agriculture than that for traditional agriculture, this indicates an increase in the efficiency of the use of economic resources in the production of these crops by bio agriculture compared to traditional agriculture.

the results also showed that the tomato crop has superiority the rest of the vegetable crops at the level of all economic efficiency criteria used in the study, followed by zucchini, followed by pepper.

In light of the findings of the research, it is recommended that the following be necessary: (1) Increasing the effectiveness of the agricultural extension system through training courses to increase farmers' experiences and encourage them to turn towards bio agricultural production free of fertilizers and chemical pesticides.

(2) Motivating the specialized companies to produce biofertilizers under the supervision of the scientific centers, With the necessity of establishing fertilization programs that suit the type soil and plant.

(3) The necessity of providing improved varieties of seeds and seeds that are highly productive and disease-free to produce crops that comply with international specifications for export.

(4) The expansion of the use of means of resistance or biological control of harmful agricultural pests, which limits the use of chemical pesticides.
