Time of pruning application and mixing prunings of varying qualities could be important management options to increase the rate of nitrogen recovery from multipurpose-tree prunings that are used as a source of nitrogen to crops. A field experiment was conducted in the semiarid zone of Zimbabwe to test this hypothesis, using prunings of calliandra (Calliandra calothyrsus) and leucaena Cited by:   An illustration of an open book.

When multipurpose-tree (MPT) prunings are used as a source of nitrogen to annual corps in agroforestry systems, it is important that high levels of N recovery are attained.

In order to test the effect of pruning quality and method of pruning application on N-recovery rates, a field experiment was conducted using prunings of five MPT species and two methods of application (surface versus Cited by: Mafongoya PL and Nair PKR () Multipurpose tree prunings as a source of nitrogen to maize (Zea mays L.) under semiarid conditions in Zimbabwe.

Nitrogen Fixing Trees - Multipurpose Pioneers Nitrogen fixation is a pattern of nutrient cycling which has successfully been used in perennial agriculture for millennia.

The effects of adding leaf mulches of Grevillea robusta, Cassia siamea and Gliricidia sepium on the rate of soil and water runoff from a crop field (of maize) were studied during two cropping seasons (August to August ) on an alfisol under semiarid conditions at Machakos, Kenya.

The experiments were conducted during the /12 growing season in Chapadão do Sul and Selvíria Cities, State of Mato Grosso do Sul, Brazil. Sesbania seedlings were interplanted with maize during maize sowing at 0, or 14, trees ha–1, in factorial combination with inorganic N fertilizer at 0 or 48 kg N ha–1 (half the.

Nitrogen-recovery rates in relation to pruning quality and method of application. In an attempt to improve or sustain crop production without costly inputs, low input crop production technologies using leguminous trees were investigated.

Special emphasis was placed on the use of tree prunings as sources of manures, either from intercropped trees or from outside the system. Four field experiments were conducted in the 'uplands' of Sierra Leone.

Author summary Nitrogen is an essential nutrient for plants, and for many nonlegume crops, the requirement for nitrogen is primarily met by the use of inorganic fertilizers.

These fertilizers are produced from fossil fuel by energy-intensive processes that are estimated to use 1% to 2% of the total global energy supply and produce an equivalent share of greenhouse gases.

Because maize (Zea. Mahua, a tree of Indian origin, has been known from prehistoric times (Plate ). Mahua is a multipurpose tree mostly grown on wastelands in the north and central parts of the country where, generally, tropical and subtropical climates prevail (Chateerjee and Parakashi, ).

It grows well on a wide variety of soils including alluvial soil in. Mafongoya PL; Nair PKR; Dzowela BH, Multipurpose tree prunings as a source of nitrogen to maize under semiarid conditions in Zimbabwe.

Agroforestry Systems, 35(1) Martínez Quesada E; Pérez M, Nitrogen fixing trees in nature and agriculture In nature, when nitrogen fixing trees drop their leaves or die back, the organic matter and fertility they accumulated in their tissues is passed on to other plants.

This process is the major source of nitrogen fertility in tropical ecosystems. When nitrogen fixing. Prunings from inoculated trees added times more nitrogen than the ones from uninoculated trees, with maize yield increases of (inoculation with Rhizobium strain IRc ) and (inoculation with Rhizobium strain IRc ) t ha The potential of alley cropping maize and cowpea with giant leucaena (Leucaena leucocephala) cultivar K was studied on an Entisol in Southern Nigeria.

The crops were grown in 4 m wide alleys formed by periodically pruned leucaena hedgerows. The effect of application of leucaena prunings, nitrogen fertilizer and tillage was studied. Despite the very intensive pruning regime (five prunings. A field experiment was conducted to determine the patterns of decomposition and nutrient release from green manures of different hedgerow tree species (Calliandra calothyrsus, Cassia spectabilis, Eupatorium inulaefolium, Flemingia congesta [F.

macrophylla], Gliricidia sepium and Tithonia diversifolia) growing in contour hedgerow intercropping systems. The trees, managed as hedgerows, are grown in wide rows and the crop is planted in the interspace or 'alley' between the tree rows.

During the cropping phase the trees are pruned and the prunings used as green manure or mulch on the crop to improve the organic matter status of the soil and to provide nutrients, particularly nitrogen, to the crop. Ambayeba Muimba-Kankolongo, in Food Crop Production by Smallholder Farmers in Southern Africa, Relay Fallow Cropping.

This system involves planting nitrogen-fixing trees 3–5 weeks after food crops, such as maize, have been sown. Some of the tree species like S. sesban can be transplanted into the standing crop using bare-rooted seedlings, whereas others such as T.

Three-level plant production, including pasture, shrubs with edible leaves and trees that may also have edible leaves, are examples of silvopastoral major development of such systems so far is in tropical and sub-tropical countries.

In the humid lowlands of West Africa, prunings and pollardings of leucaena provide fresh and dried leaf material to be put on the soil to improve its nitrogen content. Maize yield responses in on-station and on-farm testing of Leucaena leucocephala in alley cropping have been positively high (Table 4) ranging from 10 to 70 % increases over.The mimosa or Persian silk tree (Albizia julibrissin) is a good or excellent nitrogen fixer (estimates vary).
