Contour ploughing

Contour ploughing should be used on steep slope areas. The land is ploughed perpendicular to the slope, alongside contour lines that curve around the arable land. Contour lines favor infiltration of rainwater as water run-off is stopped. So the risk of soil erosion and the formation of gullies is reduced and the availability of water for the annual crops is increased. The soil conserving effect of contour lines can be augmented by planting grass strips, bushes or hedgerows alongside them.

Agricultural crops are suffering increasingly from climate change in Tajikistan; manifested among others by shifting rainfall patterns and higher temperatures during summer months, which increases water stress for the plants. Through contour ploughing, rainwater infiltration is improved which in turn increases the available water reserve of the soil and ensures better development of annual crops.

Many farmers are convinced that contour ploughing is an adequate measure for reducing soil erosion and increasing the availability of water for their crops. However, most of them do not have a tractor of their own and have to engage agricultural service suppliers for preparing their land. The latter frequently do not plough following contour lines alleging that this is time-consuming and damaging to their engine. A possible solution could be that farmers interested in contour ploughing will purchase single axle tractors, which are relatively affordable and will allow them doing contour ploughing by themselves.

Fencing

Due to large flocks of livestock, fencing often becomes necessary for annual crops, especially if the cultivated fields are located close to roads, or livestock corridors. There are several forms of fencing practised in Tajikistan. Fencing with mesh wire is effective but expensive. Unlike natural fences, mesh wire fences will not create additional income through fruit yields or timber.

Whenever it is possible, natural, local materials (e.g. branches, brushwood, stones, wooden sticks etc.) should be used for fencing. These materials are cheaper than mesh wire or concrete and offer habitats for beneficial insects and other pollinators. Living fences established from local trees and bushes, preferably with spines (hawthorn, cherry plum and barberry) are even more suitable as they contribute to biodiversity and provide firewood and wild fruits.  They, however, may require protection and watering in the first years of establishment.

If stones are available on-site, fencing with stone walls may be considered as well. Natural stone walls are not only durable but also create habitats for pollinators, other insects and small mammalians.

Many farmers have to constantly worry about having their fields entered by livestock passing through to summer pastures.  This creates conflicts within the community and with herders. By fencing their fields the family members are relieved from this worrisome task of guarding their plots and the time can be used for more effective tasks. 

Fencing is necessary on most of the irrigated annual crop fields and farmers are willing to make their own contribution for fencing their plots. It worked well when the project contributed with the mesh wire and the farmers put the sticks and the labor force for establishing the fence. However, the project team recommends piloting sustainable fencing mechanisms or micro-credits to reduce the dependence on project inputs and hence to reach more farmers.

Community-based seed banks

Due to rising demand for hybrid varieties, seeds of local varieties of vegetables and annual crops and have become increasingly unavailable at local markets. The advantage of local varieties is that they stem from open pollination, i.e. their seeds can be reproduced at the village level. However, conserving the purity of the varieties requires constant control. Plants that do not demonstrate the characteristics of the variety should be sorted out.

It is recommended to conserve seeds of local varieties by storing them in local seeds banks. If no seed bank is in place, the establishment of a new one should be supported to ensure the long-term availability of genetic material on site. 

Collection, reproduction and exchange of local varieties of seeds is a tradition that some farmers take from one generation to the next. Moreover, the spirit of mutual collaboration among farmers is seen in frequent exchange of seeds for free. Acknowledging the importance of such a practice and supporting farmers in managing seedbanks can ensure that the local varieties are conserved, available to interested farmers and passed on to the next generations.

The custom is such that farmers exchange one type of seeds for another. Often the farmers who are maintaining a community-based seed bank also give the seeds they have for free. This might work in some other countries, with a similar mentality, however, to ensure the sustainability of a community-based seed bank, it could be an option to set a price for the seeds.

Moreover, connecting the community-based small seed banks managed by farmers and bigger institutions such as the National Republican Center for Genetic of Science which have large gene banks, facilitates the exchange of local varieties and landraces between villages and districts as well.

Harvest and post-harvest management

Adequate harvest and post-harvest management are especially important for the production of fruits, berries, vegetables and herbs. These should be stored in a dry and cool, but frost-protected storage space, which should be disinfected in advance. Especially, mice are a common threat to the most storage facilities, contaminating the products and hence rendering future sales impossible. The use of pesticides should be avoided for controlling pests as these contaminate food products. Instead, various types of traps should be used.

When storing fresh fruits like apples, harvesting should be handled cautiously, in order to minimize the risk of putrefaction.

Storing apples and potatoes together should be avoided as apples produce ethylene, which can cause potatoes to sprout ahead of time.  

Fruits also can be preserved after-harvest by making compote, jam or by drying. 

Like fruits, many vegetables can be preserved in jars, while others, such as tomatoes, can be dried. The easiest and cheapest method for storing root vegetables like carrots, beetroot, radish etc. is to keep them in clamps covered by straw and earth to ensure protection from frost. The clamps should be controlled regularly to prevent infestation by pests, especially mice.

Kitchen gardens play an important role in food and nutrition security in remote areas. Farmer families rely on the harvest of the products from the kitchen gardens throughout the year and are therefore eager to improve their harvest and post-harvest management knowledge and skills.

The farmers in different areas have different practices for proper storing and preserving fruits and vegetables that pass through generations. Organizing exchange visits among farmers from different areas enables to spread best practices.

Diversifying a kitchen garden contributes to a rich diet, however, farmers should have an understanding of harvest, use, storage and processing of each crop. Over the course of the project, it was learned that it is difficult to provide enough information on these topics in a single training session. More frequent training is needed to enlarge farmers knowledge on new crops concerning plantation, growth, harvest, and post-harvest management. 

Crop Rotation

Crop rotation means planting different annual crops in a particular order over several years on the same field. Crop rotation helps to ensure long-term soil fertility as crops from different families have different requirements in terms of nutrients and rooting depth. Moreover, it prevents the accumulation and propagation of soil-borne diseases and pests. In Tajikistan, cultivating the same cash crops, e.g. potatoes in irrigated lands, is generally preferred over crop rotation.

A concept of thorough crop rotation includes cultivating legume fodder plants as alfalfa or esparcet for several years, which substantially improve soil quality. Moreover, pulses (chickpeas, green peas, lentils) can be used to promote crop rotation and crop diversification. These can also be planted as a second crop. Simultaneously, pulses fix nitrogen and thus improve soil fertility. Most of these crops besides attract pollinators and provide suitable habitats for bees.

Many farmers usually divide their kitchen garden plots into two main parts – one for potato (as it is one of the most consumed staple food) and the other one for all other kinds of vegetables and herbs. Since the positive effects, such as an increase in yield and reduction of pests and diseases can be observed right away, farmers in Tajikistan are usually willing to introduce crop rotation in their kitchen gardens.

Crop rotation is practised in Tajikistan, however not in a systematic and thorough way.  Unfortunately, most farmers are not able to implement complete crop rotation systems including cultivation of fodder plants and green manure, as available land resources are limited. Therefore, farmers are obliged to receive rather immediate effects instead of implementing complete crop rotation systems which will preserve soil fertility in the long-term.

Cultivating a second crop as crop rotation is only possible if there is sufficient irrigation water available and the vegetation period is long enough for the second crop to ripen. 

Preparing compost

By decomposing organic matter, natural soil fertilizer can be generated from what is usually regarded as waste. Organic matter as weeds, leaves, cut grass, residuals from harvest, animal dung, ash, green and brown pruning material, kitchen waste, such as eggshells and vegetable peels and other organic materials are mixed and decomposed by microorganisms for producing long-acting manure.

Compost not only improves the soil structure but also its porosity, creating a better environment for the root system of plants. It also increases the permeability of heavy soils and reduces erosion and runoff by increasing the soil's water retention capacity.

Compost supplies a variety of macro and micronutrients and in general a significant amount of organic matter to the soil.

Compost also can be used for preparing liquid manure, a very quick-acting organic top dressing which can be applied if vegetables show a deficiency of nutrients or are in a phase when they need many nutrients, e.g. tomatoes after flowering. 

Given the climatic conditions in Tajikistan, with very dry summer and cold winter, compost is normally produced in pits. Most commonly, a two-pit system is recommended.

Preparation of compost is easy and allows using and recycling own resources. This is especially important in Tajikistan where farmer families lack resources for purchasing synthetic fertilizer. 

A quick acting and effective organic top dressing can be prepared from compost.

A problem with compost preparation in Tajikistan is that farmers frequently prefer giving organic matter, mainly weeds as fodder to animals instead of composting it. Additionally, compost preparation faces some challenges in Tajikistan due to climate conditions; during summer activity of microorganisms is hindered by drought and during winter by the cold. Therefore, compost sites should be established in pits, watered regularly in the summer and covered by a tarpaulin in winter.

Prunining and formation of fruit trees

In order to develop good quality fruit yields and to enable the association of fruit growing with vegetable or fodder production in the long-run, optimal fruit tree formation is vital. From the beginning of their lifecycle, fruit trees should be formed by pruning, binding up and spreading branches. For building up stable and light-flooded trees, skeleton and fruit branches should be clearly differentiated. In the later stages of its lifecycle, maintenance pruning is used to remove superfluous fruit branches, shoots and deadwood. This allows sunlight to penetrate the inward of the tree, offering the conditions to produce bigger fruits that taste better. When fruit trees become very high and quality of fruit decline, they can be rejuvenated through rehabilitation pruning. Adequate pruning also can prevent pests and diseases, as is ensures that the trees are not too dense, and wind can pass through. The surface of leaves will consequently dry quickly after rain or dewfall and consequently spores of diseases as powdery mildew will not germinate.

An exemplary orchard with adequately pruned trees which produce high-quality fruit serves as motivation for farmers to replicate this seemingly easy, yet very important technique. Small incentives, such as pruning scissors and saws distributed during the practical parts of the training sessions have also proved to be very motivating.

Most farmers in Tajikistan lack knowledge about adequate pruning, which is why quantity and quality of fruit production as well as associated crops lags its potential. The experience shows that a single round of training might not be enough for the farmers to adopt adequate  pruning techniques.
