Abstract

This research aims to reveal properties of  the compost garbage, and to study the ways of  its use in the Cultivation and breeding of some plants (Okra  Hibiscus esculentus  , Tobaco sp, Aubergine Solanum melongena). Where the research was divided into two parts: the first section was laboratory work by taking samples of compost and its mixture with the soil and analyzing its properties. Six replications were taken from each treatment used, which are three treatments: the first is [A 100% compost], and the second is[ B  75% compost + 25%. Agricultural soil], and the third [ C 100% agricultural soil] and the analyzes were carried out on 11/2/2017. The second section is an agricultural work by By doing three tests; The first one: possibility of germination of okra seeds and the cultivation of their seedlings on compost and its mixtures, and the second: Is  the use of compost in fertilizing tobacco seedlings, and the third: Is a comparison between the growth and development of Aubergine seedlings in greenhouses with and without compost (75%).  The results of the analysis showed the good content of organic matter and nutrients and an excellent ratio of C / N, but a high pH value was observed, and a high salinity value in the event that the compost was not washed,  and the results of the tests showed the ability and validity of compost to improve the germination rate of vegetables after mixing it with soil by 75%. Compost and not to be used for germination alone without mixing with the soil.
