Estimation of plant nutritional status by Vis–NIR spectrophotometric analysis on orange leaves [Citrus sinensis (L) Osbeck cv Tarocco]

Menesatti, P; Antonucci, F; Pallottino, F; Roccuzzo, G; Allegra, M; Stagno, F (Elsevier, 2010-02-20)

Nutritional status in citrus plants, which is used as a guide for fertilisation, is normally determined by chemical analysis of leaves. According to standardised procedures, this is a destructive method. Leaf analysis ...
Impacts of Climate Variability and Change on Rainfed Sorghum and Maize: Implications for Food Security Policy in Tanzania

Msongaleli, Barnabas M; Rwehumbiza, Filbert; Tumbo, Siza D; Kihupi, Nganga (2015-04-15)

Concern about food security has increased because of a changing climate, which poses a great threat to food crop productivity. Climate change projections from the Coupled Model Inter-comparison Project phase 5 (CMIP5) ...
Understanding Farmers Information Communication Strategies for Managing Climate Risks in Rural Semi-Arid Areas, Tanzania

Churi, Ayubu J; Mlozi, Malongo R. S; Tumbo, Siza D; Casmir, Respickius (International Journal of Information and Communication Technology Research, 2012)

Crop production risk caused by climate variability cannot be managed in the absence of climate information. Despite the use of various communication strategies by rural communities in Tanzania, access and use of agricultural ...
Indigenous knowledge as decision support tool in rainwater harvesting

Mbilinyi, B.P; Tumbo, S.D; Mahoo, H.F; Senkondo, E.M; Hatibu, N (Elsevier [Commercial Publisher], 2005-08-15)

Rainfall patterns in semi-arid areas are typically highly variable, both spatially and temporally. As a result, people who rely com- pletely on rainwater for their survival have over the centuries developed indigenous ...
