An efficient protocol for indirect somatic embryogenesis and shoot organogenesis from leaf segments of date palm (Phoenix dactylifera L.) CV. Quntar

The establishment of an efficient protocol for plantlets regeneration and micropropagation from leaf cultures of date palm cv. Quntar is reported. The two types of leaflet segments used in the experiment )First piece of leaf base which have white color, and second piece of leaf tip which have green color(, were taken from micro propagated shoots of date palm cv. These leaf segments were in vitro culture on MS media...

Dispersion of proteins from Moringa oleifera seeds using pouche immersed in aqueous medium

Due to the need for proper water quality for human consumption, some studies have developed new treatment techniques. Some have used a natural coagulant based on Moringa oleifera, which has the capacity to clarify turbidity water and has anti-microbial properties. This paper aimed at developing a new technique to apply the coagulant. This technique consists of putting the M. oleifera powder into pouches. Five different...

Assessment of variation in pear genotypes through genetic divergence and cluster analysis using D2 statistics

The genetic divergence among twenty-three pear genotypes under the present study was of medium quantum. The studied genotypes, on the basis of total variability were grouped into three distinct clusters. Maximum number of cultivars were accommodated in Cluster II (Ishiwase, Seckel, Anjou, Beurre Hardy, Lisnova Karavista, Jargonelle, Kala Hathi, Autumn of Yaklove, Kashmir Pear, Hengal, Flemish Beauty, Awal Number and...

Indigenous knowledge system weather forecasts as a climate change adaptation strategy in smallholder farming systems of Zimbabwe: Case study of Murehwa, Tsholotsho and Chiredzi districts

The smallholder sector is vulnerable to climate change due to its reliance on rainfed agriculture and has the least ability to adapt. Based on appropriate weather forecasts, farmers can mitigate and adapt to climate change through sound crop management decisions. A study was conducted to explore indigenous knowledge system (IKS) weather forecasts as a climate change adaptation strategy in smallholder farming systems of...

Genetic analysis in a six parent diallel cross of cassava (Manihot esculenta Crantz)

There are concerted efforts in promoting cassava production in sub Saharan Africa as a staple food crop as well as income earner at both household and commercial level. These efforts can bear meaningful results if breeding strategies are properly coordinated. Efficient breeding methods require a thorough understanding of the genetic background of planting materials. Therefore, a genetic study was conducted to establish...

An agronomic and economic evaluation of lettuce cultivars intercropped with rocket over two cultivation seasons

The objective of this study was to investigate the agronomic and economic viability of lettuce intercropped with rocket over two cultivation seasons. The experimental designs were in randomized blocks in 3 × 3 + 2 factorial arrangement with four repetitions. The treatments were made up of a combination of three lettuce cultivars (Elisa, Veronica and Lucy Brown) and three cultivation systems (monocrop, intercrop...

Growth of eucalyptus plants irrigated with saline water

The study was aimed at evaluating the growth of eucalyptus seedlings irrigated with saline water. It was conducted on full-sun bench in the Goiás State University. The experiment was set up following the completely randomized design, with five treatments (plants irrigated daily with water with an electrical conductivity equal to 0; 2; 4; 6 and 8 dS m-1) and six replications. The eucalyptus plants showed small...

Factors influencing maize crop production at household levels: A case of Rukwa Region in the southern highlands of Tanzania

Production of staple food occupies an important part in Sub-Saharan Africa’s agricultural production. Maize crop in particular is the most important staple food in this area. The article mainly examines households’ socio-economic characteristics affecting maize production in Rukwa in the context of the market reforms carried out in Tanzania in the mid 1980’s. Rukwa region is one of Tanzania’s...

Natural vulnerability of water resources in the Formoso River basin, Northern Brazil

The natural vulnerability characterization provides fundamental support for identification of areas more susceptible from the hydrology point of view, assuring the maintenance of water resource features. In this context, this study aimed to characterize the natural vulnerability of water resources based on long-term streamflows, base flow and aquifers’ susceptibility to contamination, for Formoso River basin,...

Can an anti-erosive Andropogon gayanus live hedge help regulate millet stem borer infestation in neighbouring millet fields?

From 2008 to 2010, the effect of a wind erosion-alleviating practice, that is, planting of windbreaks of the perennial grass Andropogon gayanus Kunth on the populations of millet stem borer (MSB) Coniesta ignefusalis (Hampson) (Lepidoptera: Pyralidae) and the damage induced by this pest to pearl millet, was studied at Sadore (Niger). The extent of bored stems in the A. gayanus hedge bordering millet plots (23% on...
