Technology of non-seedling cultivation of solanaceous crops

Author: Knowledge Management in CACILM Phase II, ICARDA.

Definition of technology:

Mulching beds with black polyethylene film and nested seeding of tomato, pepper, eggplant and other crops into holes allows cultivating solanaceous crops by a non-seedling method.

Brief summary of technology:

In Uzbekistan, despite long frost-free periods, Solanaceae crops (tomatoes, peppers, eggplant) are cultivated by transplanting seedlings. The main disadvantages of this method are firstly the cost of production of seedlings, and secondly the oppression of the root system of plants due to breakage of filamentary tips of the taproot as a result of picking and hauling seedlings. Accounting for the soil and climatic conditions of Uzbekistan, a more promising technology of non-seedling planting is developed. The technology is as follows: phosphate fertilizers (ammonium phosphate) are applied in the form of band and incorporated into the soil of a carefully prepared field, and a mulch of black polyethylene film with a width of 50 cm is laid on the surface of the field. The film edges with 10 cm on each side are buried into a soil, the open parts of the film are punctured along the axes in increments of 25-30 cm and a diameter of 2-2.5 cm, in which the seeds are sown to a depth of 1.5-2 cm. After planting, irrigation furrows are made.

Implementation of the non-seedling technology of cultivation of solanaceous crops compared with a seedling technology will reduce the need for the construction and heating of greenhouses, manual labor for transplanting, and water consumption for irrigation.

As a result, the number of agro-technology operations is reduced (by 3-4 operations), which in turn will reduce the cost of diesel fuel by 51.3 l/ha, of machine labor by 9.2 person/day, and for workers by 669.8 person/day.

Location: Agro-firm “Tashtulabiy”, Zangiota district, Tashkent province.

Area of technology application: 15-20 ha.

Stage of intervention: alleviation / reduction of land degradation.

Main land use issues and the main causes of land degradation:

The conventional transplanting method causes soil compaction, deterioration of water-physical properties due to multiple irrigation and agro-technical activities.

Assessment

Impact of technology

Main advantages:

- reduced number of farming operations and costs of manual labor;

- saves fuel and lubricants;

- there is no need for greenhouses for growing seedlings.

Main disadvantages:

- the need for large quantities of film;

- disposal of used film.

Acceptance/adoption of technology: external financial support is required.
