Assessment of the potential of Siam weed (Chromolaena odorata) in enhancing soil fertility status in Serengeti District, Tanzania

Mbalila, Schola (Sokoine University of Agriculture, 2015)

Siam weed (Chromolaena odorata) is a plant that has infested a large area of agricultural land in Serengeti district and has adversely reduced crop land and crop yields. It is encroaching land and especially in the famous ...
Assessment of uranium levels in waterand soils and its uptake by sorghum and sunflower in Singida Urban District, Tanzania

Kaishwa, S. J. (Sokoine University of Agriculture, 2016)

In Tanzania, uranium deposits have recently been found in Bahi and ManyoniDistricts. Due to suspected high uranium levels in water sources as reported by District water authoritiesin Singida District, this study was carried ...
Biological nitrogen fixation in legume-legume and legume-cereal intercrops: Effects on yields of subsequent maize crop in Central Malawi

Njira, K. O. W. (Sokoine University of Agriculture, 2016)

Declining soil fertility continues to be one of the most important challenges in Malawi’s crop production systems, with nitrogen considered as the most limiting nutrient element. However, food legume crops such as pigeon ...
Carbon sequestration and nitrogen addition in selected soils of Morogoro, Mbeya and Ruvuma under maize-soybean intercropping and rotations

Hamadi, Said (Sokoine University of Agriculture, 2022)

This study was conducted in some selected soils of Morogoro (Magadu) and Mbeya (Uyole) regions of Tanzania to classify and characterize their properties. Two representative pedons (SUARAT-P1 and UYOLE-P1) were dug and ...
Characterization of selected gypsites of Tanzania and assessment of their effectiveness as plant nutrient source and soil amendment

Andrea, Primitiva (Sokoine University of Agriculture, 2015)

This study was carried out to assess the suitability and effectiveness of gypsite as soil amendment in release of Ca and S. This is because besides the high potential of gypsite in improving crop yields in some countries, ...
Characterization of vermiculites from the Mozambique b elt of Tanzania for agricultural applications

Marwa, Ernest Melkiory Magesa (University of Aberdeen, 2009)

Crop productivity in Tanzania is generally low and this is partly due to inadequate and poor retention of plant nutrients and moisture by some soils. The country has several vermiculite deposits, but none of them are ...
Comparative effects of minjingu phosphate rock and triple super phosphate on residual p in an ultisol

Kalala, Asheri Mwamba (Sokoine University of Agriculture, 2011)

The use of relatively high rates of phosphorus (P) is known to result in a build up of P in soils and there are frequent claims that the use of phosphate rocks results in higher residual effects than water soluble sources. ...
Developing an integrated soil fertility management decision support tool for arabica coffee (coffea arabica) in selected areas of northern Tanzania

Maro, Godsteven Peter (Sokoine University of Agriculture, 2014)

Coffee is one of the major export crops in Tanzania, contributing 24% to the agricultural gross domestic product (AGDP). The crop contributes directly to the livelihoods of over 420 000 farm families and indirectly to over ...
Effect of liming acid soils on physico-chemical characteristics of the soils and coffee seedling vigor in Mbozi District, Tanzania

Mfaume, D. P. (Sokoine University of Agriculture, 2019)

Soil acidity is one of the most important soil factors affecting crop growth and ultimately yield and profitability of coffee in Mbozi District Tanzania. Soils tend to be naturally acidic in areas where rainfall is ...
Effect of tillage, farmyard manure and potassium rates on the perfomance and profitability of cassava in selected districts of Kagera, Tanzania

Merumba, Mgeta Steven (Sokoine University of Agriculture, 2022)

In Tanzania cassava (Manihot esculenta, Crantz) is the second most important food security crop after maize. Its roots produce at least 30% of starch on dry weight basis, which is the major source of dietary energy, ...
Effect of water management systems with different nutrient combinations on performance of rice on soils of Mvumi, Kilosa district, Tanzania

Massawe, Ikunda Herman (Sokoine University of Agriculture, 2016)

A comprehensive study was conducted on soils of Mvumi Village, Kilosa District, Tanzania to investigate the effect of water and nutrients on the growth and yield of rice so as to improve rice production by manipulating ...
