Yield estimation based on agronomic traits in vegetables under different biochar levels by Ccopi Trucios, Dennis, Requena Rojas, Edilson Jimmy, Arias Arredondo, Alberto, Taipe Crispin, Maglorio, Marcelo Matero, Jhonny Demis, Pizarro Carcausto, Samuel Edwin

“…Simultaneously, UAV-captured multispectral imagery provided spectral indices that were integrated with agronomic data into machine learning models: linear regression, support vector machines (SVM), and regression trees (CART). Results demonstrated significant vegetative growth enhancement and yield increases across all crops, with the 30 t ha-1 application rate producing optimal outcomes. …”

Effects of trees on infiltrability and preferential flow in two contrasting agroecosystems in Central America by Benegas Negri, Laura A., Ilstedt, Ulrik, Roupsard, Olivier, Jones, J., Malmer, A.

“…However, in land manage-ment practices where understorey perennial vegetation makes up a large proportion of the cover, suchas for coffee agroforestry systems, the effect of trees on infiltration-related ecosystem services could beless pronounced.…”

Long-term observations of rain forest succession, tree diversity and responses to disturbance by Sheil, Douglas

“…The lowest species density observed in the study is a 1940s record of c. 10 species >= 10 cm diameter ha¯¹ in monodominant Cynometra [Caesalpinoidae] forest and the highest record is c. 61 ha¯¹ recorded in 1992, in the youngest vegetation type monitored. These observations indicate both the volatile nature of tree-richness patterns and the limitations of simple models as aids to interpretation when confronted with real patterns of long-term change.…”

Determinants of forest and tree uses across households of different sites and ethnicities in Bangladesh by Ahammad, R., Stacey, N., Sunderland, T.C.H.

“…The greater the size of the landholding, the more likely timber was used for both subsistence and cash income, but the less the reliance on other products (fuelwood, thatch grass, vegetables). Our findings suggest that the location and ethnic characteristics of the rural households are important for understanding the diverse needs for forest and tree use, and should be factored into the site-specific management and sustainable use of forest and tree resources in Bangladesh and other tropical developing countries.…”

A participatory approach for tree diversification in cocoa farms: Ghanaian farmers experience by Asare, R., Asare, R.A.

“…Farmers used the framework to critically characterize and select desirable non-cocoa trees according to biophysical and socio-economic attributes, and then planted these species onto farms with the aim of providing favorable vegetative cover for cocoa, as well as securing valuable sources of timber and non-timber products. …”
