Striga asiatica is a serious problem in upland rice in Kyela Tanzania. The use of inorganic nitrogen fertilizer urea assures control of the weed. Resource poor farmers cannot adopt the technology due to unavailability ...
Soil fertility status and response of rice to nitrogen, phosphorus and farmyard manure under rainwater harvesting systems in semi arid areas of Maswa, Tanzania.

Kajiru, Geophrey Jasper (Sokoine University of Agriculture, 2006)

In semi arid areas of Tanzania, rainfed lowland rice production is constrained by inadequate plant nutrients and soil moisture thus restricting plant growth culminating into very low yields. With the adoption of appropriate ...
An evaluation of adoption and sustainability of soil conservation practices under small scale farming system of Adama district in Oromia region, Ethiopia

Waritu, Gerishu Bati (Sokoine University of Agriculture, 2007)

Over the years, numerous intervention approaches have been launched to promote improved technologies in order to attain sustainable development. However, extension approaches, which have been the dominant rural development ...
Soil and water conservation practices in the Uluguru mountains: the influence of high value crops promotion

Malisa, Emmanuel Timothy (Sokoine University of Agriculture, 2009)

In western Uluguru Mountains, professionals have introduced soil and water conservation (SWC) practices which, if properly followed, would conserve the soil and promote agriculture. Various high value crops (HVC) promotion ...
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 ...
Effects of copper concentration in soil on prolife ration and survival of rhizobia, nodulation and biological nitrogen fixation in beans, cowpeas and soybeans

Tindwa, H (Sokoine University of Agriculture, 2010)

A study was conducted in which two strains of the fast – growing bean rhizobia- PV 1 and PV 2 and two others of the slow – growing bradyrhizobia for cowpeas and soybean- CP 1 & GM 8 , respectively, were used to test their ...
Utilization of sisal bole juice - inulin as an Alternative chemical feedstock in citric acid Production

Ngonyani, Consolatha Joachim (University of Dar es Salaam, 2010)

Tanzanian Sisal industry is characterised by a severe biomass production for wastage that is (2:98) product to waste ratio. Among the waste, 100% of plant residues in a form of sisal boles, that are made of hydrolysabl ...
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. ...
Response of tomato (lycoperscon esculentum m.) to coffee pulp compost, Minjingu phosphate rock and coffee pulp – Minjingu phosphate rock compost applied to a chromic acrisol

Shitindi, Mawazo Jamson (Sokoine University of Agriculture, 2011)

Socio-economic factors influencing conservation and development trade-offs on Uluguru mountains, Tanzania

Amos, Mkami (Sokoine University of Agriculture, 2012)

Given the reality that trade-offs are rules rather than exceptions there is a need to acknowledge them and assess how different groups of people influence conservation and development choices. This study was conducted ...
Evaluation of soil fertility status and optimization of its management in sesame (sesamum indicum L.) growing areas of Dodoma district

Sanga, Daines Leogin (Sokoine University of Agriculture, 2013)

A study was conducted in Dodoma district, Dodoma region Tanzania to assess the soil fertility status for sesame production. The study was initiated due to the continuous decline of sesame yield to alarmingly low levels. ...
