Sustainable fruit production by soil moisture conservation with different mulches: A review

It is essential to find ways and mean to increase the yield and lessen the cost of production so that there is enough fruit production to meet the requirement of the consumers. The yearly growth of plants, excessive growth of weeds and production of fruits deplete the soil of its nutrient reserves resulting in reduction of native-soil fertility. Mulching of organic and inorganic materials create favourable conditions...

Effect of culture media on in vitro germination rate and shoot-forming potential of Codonopsis javanica (Blume) Hook f. & Thomson artificial seeds

Being a tropical country, Vietnam has an exceptional diversity of medicinal plants, particularly in the highland provinces (for example, Lam Dong, Daklak and Kontum provinces). However, a list of many rare medicinal plants are recorded in the Vietnamese Red Data Book and most of them are globally threatened. In this study, the effect of the type of culture media and the concentration of phytohormones on germination,...

Possibility of using the intermediate mature stage of Garcinia kola heckel seeds to shorten the germination time

Garcinia kola is used as chew-stick for dental care in West Africa. The species is nearly commercially extinct in nature, and its propagation is hampered by seed germination problems. The current study investigated seed germination responses of Garcinia kola at different maturity stage. The experiments were conducted at the Central Laboratory of Biotechnology of the Centre National de Recherche Agronomique (CNRA)...

Analysis of traders’ perception and adaptive techniques in the control of kola weevil, Balanogastris kolae

A survey involving 160 kola nut traders who were randomly selected in two local governments of Ondo state was conducted to examine pest management practices carried out by the traders. Interview schedule structured questionnaire was used in a multi-stage random sampling to select 40 kola nut traders from two villages in each local government. Results showed that most of the respondents were already old with the mean age...

Use of a portable chlorophyll meter to evaluate leaf Nitrogen status of tropical carpet grass

The persistence of color response after fertilizer treatments is a key indicator of turfgrass performance. Tropical carpetgrass (Axonopus compressus (Swartz) Beauv.) is widely used throughout subtropical area, was selected as the subject of this study. Five nitrogen (N) treatments applied monthlyat the application rate of both 7.5 and 15.0 g N/m2 as ammonium nitrate (AN), 2.5 and 7.5 g N/m2 as a 14-6.2-11.6 (NPK) slow...

Household food insecurity and associated factors in rural communities: A case of Kilosa District, Tanzania

Food insecurity continues to be a major contributing factor to nutrition insecurity in developing countries. A nine item Household Food Insecurity Access Scale (HFIAS) was administered twice to 307 households among three agro-ecological zones in rural communities of Kilosa District-Tanzania to measure food security. Households were surveyed once during the rainy season (February–May) and once immediately post...

Using improved varieties and fertility enhancements for increasing yield of common beans (Phaseolus vulgaris L.) grown by small-landholder farmers in Uganda

Productivity of common bean (Phaseolus vulgaris L.) in Uganda is less than 30% of the yield of improved varieties grown on research stations. This yield gap has been attributed mainly to low soil fertility and susceptibility of local varieties saved by farmers to pest and disease infestations. This study evaluated the impact of four improved varieties and soil fertility improvement on bean yields on small-landholder...

Physiological quality of mangaba seeds submitted to drying

Mangaba (Hancornia speciosa Gomes) is a native fruit to Brazil of great importance in its areas of occurrence. The aim of the present study was to evaluate the physiological behavior of mangaba seeds submitted to desiccation. The survey was conducted in the Laboratory of Seeds Analyses of Embrapa Coastal Tablelands, Aracaju, SE, Brazil. The experimental design was completely randomized with five replicates of 25 seeds...

Different sources of silicon in the embryonic development and in the hatching of Meloidogyne javanica

Silicon is the main objective of many researchers whose goal is to see its use as an inductor resistance. The action of the inductor happens in the plants, where it does not affect the pathogen directly, but the effect will contribute for its control. Therefore, the main objective of this report was to evaluate the effect of silicon on the embryonic development and the hatching of Meloidogyne javanica. For this, three...

Revaluation of activated sludge and chicken manure through composting by aerobic process

The activated sludge from the wastewater treatment plant (WWTP) of Tipaza, rich in plant sawdust, and chicken manure from the company Avicola, rich in nitrogenous matter, appears to be perfectly compatible for co-composting. The compost of these two biomasses gives a satisfactory result confirmed by the monitoring of the C/N ratio, a key indicator of the state of composts. Furthermore, the physicochemical parameters and...
