“…Nontimber native plants can be an important economic alternative in tropical agroforestry systems (Leakey and Simons 1998;Leakey and Tchoundjeu 2001;Rao et al 2004). Examples of nontimber native plants cultivated in tropical agroforestry around the world include Azadirachta indica in India (Rao et al 2004), Prunus africana and Pausinystalia johimbe, in Africa (Leakey and Simons 1998), among others.…”

“…Examples of nontimber native plants cultivated in tropical agroforestry around the world include Azadirachta indica in India (Rao et al 2004), Prunus africana and Pausinystalia johimbe, in Africa (Leakey and Simons 1998), among others. The cultivation of nontimber native tree species in a sustainable manner permits the conservation of those species and it produces high quality products demanded by internal and external consuming markets.…”

Growth and photosynthetic responses of Gallesia integrifolia (Spreng.) Harms and Schinus terebinthifolius Raddi seedlings in dense shade

et al. 2008

We analyzed the growth and photosynthetic behavior of Gallesia integrifolia ('pau-d'alho') and Schinus terebinthifolius ('aroeirinha') under shade, seeking to obtain ecophysiological information for introducing seedlings of those species in previously established cacao agroforestry systems. Considering that light intensity under the shade of cacao trees varied between 5 and 10% daylight, 5 months old seedlings were exposed to four irradiance levels (25, 17, 10 and 5% daylight) for 92 days. With shade increase both species displayed trends of decrease leaf mass per unit leaf area, leaf area per plant (LA), relative growth rate (RGR) and net assimilation rate (NAR), and increase leaf area ratio (LAR). The mean values of light-saturated net photosynthetic rate (P nmax ) in 25 and 5% daylight were 12.8 and 8.0 lmol CO 2 m -2 s -1 for G. integrifolia and 17.9 and 7.4 lmol CO 2 m -2 s -1 , respectively, for S. terebinthifolius. Based on the measurements of photosynthetic photon flux density and estimated values of photosynthetic saturated irradiance (Is) we concluded that, in all shaded conditions, the leaves of both species were under sub optimal light conditions to reach P nmax . In spite of the lowest P nmax values, RGR and NAR were significantly higher for G. integrifolia in all irradiance levels. Differences in growth rates can be explained by the higher values of LA, LAR and leaf mass ratio (LMR), as well as by the lower values of Is, photosynthetic compensation irradiance and dark respiration rates observed for G. integrifolia. Even though seedlings of G. integrifolia presented higher capacity to adapt under conditions of dense shade, we concluded that both species were under stress conditions induced by shade in light environments below 25% daylight. On a practical point of view it is possible to conclude that seedlings of both species should be introduced in light gaps, formed after the fall of big trees, or in places in which cacao trees are cultivated using large plant spacing.

“…Tree canopy cover may have played a role here in increasing the abundance of such valuable species. Many medicinal plants are grown under forest cover and are shade-adapted, and agroforestry offers a convenient strategy for promoting their cultivation and conservation (Rao et al 2004). …”

“…The light conditions under these trees were considered suitable for spice production. The ideal shade reported for most medicinal and aromatic plants in India, including cardamom and pepper is 30-50% in Karnataka (Rao et al 2004) and about 40-60% of the light intensity in the open in the Western Ghats (Kumar et al 1995).…”

Spice crops agroforestry systems in the East Usambara Mountains, Tanzania: growth analysis

et al. 2009

View full text Add to dashboard Cite

A scarcity of cultivation land calls for more intensive and productive land use in the East Usambara Mountains in NE Tanzania. Spice crops could generate cash in higher parts of the mountains, but the present cultivation methods are depleting the valuable forest resources. The trial was established at the end of 2000 to find out how the two popular cash crops, cardamom (Elettaria cardamomum (L.) Maton.) and black pepper (Piper nigrum L.), normally grown under the natural forest, will produce in intensive agroforestry system with two multipurpose farm trees, Grevillea robusta A.Cunn. and nitrogen fixing Gliricidia sepium Jacq. Results from 6 years showed that cardamom produced better with grevillea than in natural forest; 5.5 times more in the fourth year than the average in the area. The Land Equivalent Ratios for black pepper and cardamom showed that pepper intercropped with grevillea produced 3.9 times more than in monoculture whereas cardamom intercropped with grevillea and pepper produced 2.3 times more than in monoculture. Gliricidia improved the nitrogen and organic matter content of the soil over the levels found in natural forest. Soil acidity was, however, preventing the plants from using the available mineral nutrients more effectively.
