Overview of pepper (Capsicum spp.) breeding in West Africa

The genus Capsicum (sweet and hot pepper) harbors an incredible intra and inter-specific diversity in fruit type, color, shape, taste, and biochemical content. Its potential uses and benefits to mankind cover many areas such as food and nutrition, medicine, cosmetic, plant based insecticides (PBI), and income. The cash income potential combined with the fact that peppers are easy to grow, harvest, and process...

A review of regeneration and genetic transformation in cowpea (Vigna unguiculata L. Walp)

Biotechnology techniques including plant tissue culture and recombinant DNA technologies are important tools that can complement traditional breeding. Progress has been slow in cowpea (Vigna unguiculata L.), mainly due to its recalcitrant in plant regeneration and genetic transformation. Despite this, some achievements have been obtained. This review presents a consolidated account of explants used, mode of...

Elimination of lime causing clogging in emitters by chemical methods in drip irrigation

Emitter clogging is one of the most serious problems facing users of drip irrigation systems using poor irrigation water and groundwater. It can affect negatively irrigation system performance and crop yield. The objectives of this study were to to determine the appropriate HCl amount (2.5, 5, 10, 500 and 1000 ppm) and whether these acid rates could open the clogged emitters (25, 50 and 100%) with additional...

Evaluation of brown seaweed (Padina pavonica) as biostimulant of plant growth and development

An innovative horticulture nutrient and biodegradable support is described in this paper for replacing plastic culture pots. This support is prepared with Luffa aegyptica, plant having a water holding capacity higher than that of the regular soil and that is also biodegradable. Brown seaweed  Padina pavonica was incorporated as an organic fertilizer of plant growth. Chemical analysis of the aqueous...

Biomass allocation and nitrogen distribution of Pinus wallichiana Jackson seedlings under different nitrogen fertigation levels

Pinus wallichiana seeds were sown in polybags filled with sterilized riverbed sand in 2010. Seedlings were thinned out to one seedling per polybag, which were treated weekly with Ingestad pretreatment nutrientsolution for 4 weeks and then were fertigated with nitrogen levels of 0.99, 1.98, 2.97, 3.96, 4.95, 5.94, 6.93, 7.92, 8.91 and 9.90 mg and fixed levels of phosphorus, potassium, calcium and magnesium...

Effect of seaweed saps on growth and yield improvement of green gram

A field experiment was conducted during the pre-kharif season at Uttar Chandamari village in 2012 to study the effects of seaweed saps on growth, yield and quality improvement of green gram in new alluvial soil of West Bengal. The foliar spray was applied twice at different concentrations (0, 2.5, 5.0, 7.5, 10.0 and 15.0% v/v) of seaweed extracts (namely Kappaphycus and Gracilaria). Foliar...
