Current knowledge and performance of existing charcoal coolers in improving the overall quality and shelf-life of French beans

This study investigates current knowledge and performance of existing technology, ‘charcoal coolers’ in improving the overall quality and shelf-life of French beans. Data was collected primarily from a household survey using a semi-structured questionnaire administered to 45 purposively selected farmers who were selected at fixed interval. Data was analysed using the Statistical Product and Service Solutions...

Coffee straw used as mulch for germination and strength of crops and spontaneous species seedlings

The objective of this study was to evaluate the allelopathic effect of using conilon and arabica coffee straw as mulch on the emergence and development of three crops (Lactuca sativa, Cucumis sativu, Solanum lycopersicum) and three natural plants (Eupatorium maximilianii, Amaranthus hybridus and Bidens pilosa). The experiment was carried out in a greenhouse in a completely randomized design, with six repetitions. The...

Effects of sewage sludge and length on initial growth of guava seedlings

Substrate and light intensity exert influence on the quality of seedlings produced by increasing plant nutritional efficiency and growth. The objective of this work was to study the emergence and early growth of guava seedlings (Psidium guajava L.) in substrate enriched with sewage sludge and under different light intensities. In the conduction of this work, guava seeds of the cultivar Pedro Sato were used and five...

Impact of variable NPK source on water use efficiency and growth rates of winter grasses (cereals): Wheat, rye, barley and oats

Growth analysis [absolute growth rate (AGR), crop growth rate (CGR), and net assimilation rate (NAR)] and water use efficiency (WUE) response of four cool season C3-cereals viz. wheat (Triticum aestivum L.), rye (Secale cereale L.), barley (Hordeum vulgare L.) and oats (Avena sativa L.) at 30, 60 and 90 days after emergence (DAE) under eight NPK sources [S1 = 20-20-20,  S2= 20-27-5, S3 = 7-22-8, S4 = 10-10-10-20S,...

Protection of Sideroxylon obtusifolium seeds against Colletotrichum sp. with Caesalpinia ferrea extract

Sideroxylon obtusifolium (Roem. & Schul.) Penn. is a native species from Caatinga biome, but due to disorderly exploitation for phytoteraphy industry, it is in danger of extinction. Recent researches report that the diversity of vegetal species in Brazilian semiarid regions, when meticulously assessed through methods that focus on properties of molecules from different plant structures, may present a high potential...

Hydropriming of pearl millet (Pennisetum glaucum L.) in Northern and Central Burkina Faso applying six hours of soaking and overnight drying of seeds

Hydropriming of pearl millet seeds was tested during two growing seasons in Burkina Faso. A total of 32 field experiments were distributed equally between two agro-ecological zones: The Northern zone receiving on average less than 600 mm annual precipitation and the Central zone receiving 600 to 900 mm. Hydropriming was performed by soaking of seeds in water for 6 h, followed by air-drying overnight. In the Northern...

The effects of humic acid on growth and ion uptake of mung bean (Vigna radiata (L.) Wilczek) grown under salt stress

The study aimed to determine the effects of humic acid (HA) on seedlings of a salt-sensitive plant, mung bean (Vigna radiata (L.) Wilczek), grown on 50 mM (S1) and 100 mM (S2) NaCl concentrations. In controlled room conditions, mung bean seedlings were planted in pots containing torf and perlite mixture and salt effects were observed. The growth parameters were plant height, number of leaves, leaf area, leaf and stem...
