During the growth period, black bean goes through several stages of development, which differ in terms of quality, and this factor also affects the nutrition process. Black moss has development periods consisting of germination, flowering, fruiting and ripening. The results of the study of how external environmental factors affect the yield of black mallow and the development of black mallow during the growing season indicate that the life of the plant can be divided into six periods. Plants do not always require the same amount of nutrients, either in terms of quantity or quality. This factor varies depending on the growth and development of the plant and the time of the season in general. In this regard, all field crops are divided into two groups, short and long feeding during the growing season. In particular, the black moss plant is considered a plant that is fed for a long time during the growing season. It absorbs nutrients from the soil from the time it germinates from the seed until the end of the growing season. After the autumn frost hits the black mallow plant planted as a repeated crop, its growth period ends, and the black mallow seed planted in the ground in the middle of the spring season usually goes through a full vegetation period.
