ABSTRACT Rodents often damage crops throughout the growing season, from germination to harvest, thus making it difficult to understand its cumulative effects for crops such as rice that are able to partially compensate. This study examines response of rice yield to rat damage in farmer’s fields and simulated rat damage in irrigated and rain-fed rice (Oryza sativum L.) in Morogoro, one of Tanzania’s granary areas. The study was conducted at Hembeti village in Mvomero district from Septembe...
ABSTRACT Field experiments were conducted simultaneously from April to July 2012 at agro-ecologies; Bambi (Latitude 06o09’S, Longitude 039o16’E; and Altitude 20m above sea level) Central District and Kizimbani (Latitude 05o54’S, Longitude 039o16’E; and Altitude 20 m above sea level) Western Unguja district. The aim was to investigate the effectiveness of selected cultural practices (weeding and hilling-up once, twice and thrice), vine portions (apical, middle and basal) and variety (M...
ABSTRACT A field experiment was conducted during 2014/15 growing season at Tumbi, Tabora to study response of sweet potato to organic and inorganic fertilizers. The experiment was split plot laid in a Randomized Complete Block Design with four fertilizer types and different rates; 0, 50, 100, 150 (DAP), 100, 200, 300 kg ha-1 (Minjingu Mazao), 150, 250, 350 kg ha-1 (NPK) and 2.5,5.0,7.5 ton ha-1 (FYM) as main plots and three varieties (Kasinia, Simama and Ukerewe) as subplot in three replicati...
ABSTRACT An experiment was conducted in the Northern Zone of Tanzania during the growing season 2014/2015. The aim of the study was to characterize the maize landraces collected at farm level and establish the diversity that exists in Northern Tanzania for landraces maize growers. The experiment with fifteen maize landraces was laid out in randomized complete block design (RCBD) with three replications. Data were collected on vegetative and reproductive variables. Data were subjected to Analy...
ABSTRACT Laboratory and field experiments were carried out in Morogoro Region from August 2008 to June 2009 to evaluate effectiveness of locally formulated baits in managing the melon fly, Bactrocera cucurbitae (Cocquillett) (Diptera:Tephritidae). An assay was design to determine the quantity of D. elliptica that could kill more than 50% of B. cucurbitae populations, where by roots of D. elliptica were sun dried and prepare a crude extracts then were mixed with brewer’s yeast and the other ...
ABSTRACT The aim of this research was to assess for levels of drought tolerance among common bean (Phaseolus vulgaris L.) lines developed for drought tolerance; grown under non-stress (NS) and drought-stress (DS) water conditions. The research was conducted at Sokoine University of Agriculture (SUA) located at 605’ latitude south, 3703’ longitude east and 525 m.a.s.l. It was done in a screen house. The experimental design was Completely Randomized Design (CRD), two water regimes and twelv...
ABSTRACT Studies were carried out to establish the role and significance of rice stem borers as pests in rice crop in Kahama District from November, 2013 to May, 2014. Twenty rice fields in four wards of Kahama District were surveyed to assess the presence of larvae and adult moths. Each field was divided into four strata within which four quadrats were established in each. In each quadrat, the damaged rice tillers (dead heart), damaged panicles (white head) and total number of tillers and pa...
ABSTRACT Field experiments were carried out in 2006 and 2007 cropping seasons at the Teaching and Research Farm of the Department of Crop Science, University of Nigeria, Nsukka, to study the inheritance pattern of days to flowering and quantitative traits in cowpea. The experimental materials comprised 10 cowpea accessions sourced from Plateau and Enugu States of Nigeria. Reciprocal crosses were generated and the parents, F1, F2 and BC populations were evaluated for days to flowering under lo...
ABSTRACT Studies were conducted on nine (9) bambara groundnut (Voandzeia subterranea) accessions representative of cultivars cultivated in Ghana, Swaziland and Zimbabwe at the University Farms, Legon, on two planting dates.
ABSTRACT The performance of 16 cultivers of common wheat was studied at Kpong in 8 monthly plantings to
Increasing inorganic fertilizer costs for food production and energy requirement for inorganic fertilizer production suggests the need to supplement the nutrient requirement of crops through organic amendments such as crop residues, manures and composts. Combined use of organic and inorganic fertilizers can improve rice productivity and sustain soil health and fertility. A pot experiment was conducted to compare the effects of N source as compost (organic), inorganic fertilizer (inorganic) or...
ABSTRACT Smallholder farming communities of northern Namibia are generally cash-constrained and theyare situated in marginal areas where poor soil fertility and land degradation are predominant. They find it difficult to purchase mineral fertilizers and herbicides. There is therefore a need to identify cropping systems that are affordable and can improve their productivity. The integration of green manure cover crops (GMCCs) as rotational crops has been investigated to great lengths in Latin ...
Abstract This study focused on the results from the 2016/17 and 2017/18 cropping seasons from two trials, one in Liselo and the other in Mashare in the Kavango East and Zambezi regions of Namibia, respectively, on the effects of Conventional and Conservation Agriculture (CA) practices and principles on soil moisture content and infiltration. Conventional mouldboard ploughing (CTa), Sub-soiling with a Magoye ripper (SS-M) and Manual direct seeding with a Dibble stick (MDS-M) were the primary t...
ABSTRACT Pruning of diseased leaves and the use of Propiconazole (Tilt), a foliar fungicide with systemic properties, were two different recommendations made by the Ministry of Food and Agriculture to control black sigatoka, currently an important disease of plantain in the country. The two methods were evaluated from September 1995 to April 1997 at the University of Ghana Agriculture Research Station, Kade. Four treatments, namely, Tilt (0.125g ai/L), Pruning, Tilt (0.125g ai/L) + Pruning a...
