At present the need to plant trees on farms is on the increase. It is difficult, however, for smallholders to access – at the right time, in the right quantities and of high quality – the trees that they want to plant. In order to meet present and future demand for planting materials, there is a need to promote on-farm and community tree nurseries. Such nurseries can be owned and managed by individual farmers, by self-help groups, by schools, by churches and/or by a range of other local institutions. They provide income-generating opportunities, act as models for further nursery development, provide seedlings more cheaply to planters, and can raise the particular species that local people are interested in. The practice describes the various steps involved in the establishment of a tree nursery.
The floating garden practice is a local indigenous production system most successful in the wetland/submerged areas of selected south and south-western districts (Pirojpur, Barisal and Gopalganj) in Bangladesh. Floating garden agricultural practices have been adopted by local farmers for near two centuries. This technology describes how to construct and use floating gardens for seedling production of vegetable and spice crops in Bangladesh.
Air layering is a technique followed in the nursery of ornamental/horticultural crops to promote vegetative propagation.
This practice explains how the propagation process can be accelerated by a so-called “double-layering method”. This allows the nursery to use air-layering in a more efficient way and increase the nursery’s income.
The double pit planting with two trees planted next to each other allows to nearly double the productivity of trees. The application of double pit planting together with the double air-layering practice contributes to the improvement of the efficiency of used resources for the propagation and production of moringa and indirectly to poverty reduction by enhanced income of the nursery.
Transplanted aman (t. aman) rice is the major crop usually grown throughout Bangladesh during the kharif-II season (July-October), but in some years and in certain parts of the country floods hinder timely transplantation and production of this rice. Early floods delay t. aman transplantation and sometimes late floods inundate fields and cause huge damage to the standing crop. According to the circumstances and the flood forecast in a given area, farmers may decide whether to go for varieties of t. aman suitable for early or late transplantation.
This practice describes how cropping can be adjusted to the flood schedule by using early or late varieties of t. aman in order to avoid loss of crops due to flood, and eventually take advantage of the early production of rice to grow further additional crops.
Farmers in the Barind tract of Bangladesh heavily rely on rice yields for their livelihoods. The rice crop they rank as most affected by climate-related problems is t.aman (transplanted aman), grown during the wet kharif II season on about 70 percent of the rice area in the Barind tract. In dry years t.aman crops suffer from high yield reduction if transplantation is delayed due to drought. Besides, delayed transplantation leaves no time or no land to grow short duration vegetables, oil seeds (mustard) and pulses (chickpea), before the next boro rice cultivation. In the event of heavy rain the main field may be flooded and not ready for the sowing of transplanted seedlings. A solution is to temporarily plant them on high land with drainage facilities before finally transplanting them onto the main field, once it has dried out.
