Analyses of constraints related to milk production in Liptako Gourma in Niger

Livestock in Niger has great potentials. If well managed, this sector can significantly improve food security and boost poverty alleviation in the population. In order to encourage the development of local milk production in Liptako Gourma, the present study was undertaken to identify constraints related to milk production in the area. A questionnaire based survey was conducted to collect data from 360 dairy farmers....

Improved production systems for common bean on Ferralsol soil in south-central Uganda

Common bean (Phaseolus vulgaris L.) is the most important source of dietary protein in Uganda but current grain yields are low. Production is particularly low on the degraded Ferralsol soils that dominate the landscape because these soils are generally weathered, acidic and infertile. A study was done on a Ferralsol soil in Masaka District, Uganda to compare productivity and economic return to labor and management...

Effects of cultivation duration and mode on the microbial diversity of the Amorphophallus konjac rhizosphere

Amorphophallus konjac cannot be cultivated on the same field consecutively for extended periods, but can be cultivated on the same grove. The underlying mechanism for this is unknown and may involve the rhizosphere microbial community. Therefore, the different duration and mode for konjac were researched. Polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE) showed that microbial communities...

Evaluation of dietary fat sources on growth performance, excreta microbiology and noxious gas emissions in Ross broilers

An experiment was conducted to evaluate fat sources on growth performance, excreta microbiology and noxious gas emissions in broilers. Experimental birds were reared for 5 weeks and divided into two periods: Starter (0 to 3 weeks) and finisher (4 to 5 weeks). A total of 150 one day old Ross 308 broiler chicks were randomly allocated into five treatments with five replications (six birds per replicate) following a...

Mass selection for enhancement fruit yield in Edkawy cultivar of tomato under different irrigation intervals in southern of Egypt

Field experiments were carried out during the period from 2013 to 2017 in the winter season at the experimental farm, Faculty of Agriculture, South Valley University, Qena, Egypt. Improvement yield and its attributes in Edkawy local cultivar via mass selection were done for three cycles. The unselected base population (C0) and selected populations (C1, C2, and C3) evaluated under two different water availability,...

Agronomic characteristics and oil content of different genotypes of canola (Brassica napus L. var. oleifera)

The aim of this study was to evaluate the agronomic performance and oil content of 13 canola genotypes in Western Paraná, Brazil. The experiment was carried out, during the year of 2015, in the municipality of Marechal Cândido Rôndon in the west of the State of Paraná. A Randomized Complete Block Design (RCBD) was utilized with four replications. The genotypes of canola evaluated were Hyola...

Early growth and survival rates of crossbred lambs (Dorper x indigenous) under semi-intensive management at Areka, Southern Ethiopia: Effects of non-genetic factors

Stagnant early growth and poor lamb survival are the major constraints of sheep production in Ethiopia. The aim of this study was to evaluate early growth and survival rate of crossbred lambs (Dorper × indigenous, Adilo) under semi-intensive conditions. Body weight (BW, kilograms) at 0-180 days, average daily gain (ADG, g/day), pre- (0-90), post (90-180) and overall (0-180 days), and pre-weaning survival rate...

Effect of supplementing pounded Prosopis juliflora pods on hematological profiles of Afar goats fed on Panicum antidotale hay

A study was conducted on thirty two 15.5±1.4 kg (mean ± SD) male Afar goats so as to evaluate effects of increasing dietary levels of pounded Prosopis juliflora (P. juliflora) pod on their performance. Hematological values, individual feed intake and body weight gain were determined during a 90-day experimental period. Four dietary treatments were applied using complete randomized design (CRD). The...

Determinants of agroforestry adoption as an adaptation means to drought among smallholder farmers in Nakasongola District, Central Uganda

Agroforestry adoption as a drought adaptation option has an omnibus of opportunities for smallholder farmers in semi-arid regions. This study assessed the severity and frequency of drought and the determinants of agroforestry adoption in Nakasongola District. The episodes were examined using the Standardised Precipitation Index (SPI) set at 3, 6 and 12 months timescales. A cross-sectional survey using semi-structured...

Genetic diversity among papaya accessions

Genetic diversity studies provide fundamental information for characterization, conservation and utilization of available genetic resources in plant genetic improvement programs. To evaluate the genetic divergence among papaya accessions, 17 morphoagronomic variables from 59 accessions of the active germplasm bank were evaluated in an experiment at Santa Teresinha Farm, belonging to Caliman Agrícola S/A, in...
