Effect of combined doses of gamma ray and sodium azide (mutagenic agents) on the morphological traits of some varieties of okra (Abelmoschus esculentus)

Abelmoschus esculentus (okra) is a popular health food because of its high fiber, vitamin C and folate content. It is also rich in antioxidants, a good source of calcium and potassium. Three varieties of okra: Jokoso, NHAe47-4 and Beru (a local variety) were irradiated with 20, 40, 60, 80 and 100 kr doses of gamma rays then soaked in 2.0 mM and 3.0 Mm of Sodium azide for 2h with the aim of determining the effects of the...

Characteristic of an Oxisol post-cultivation of the corn using tannery sludge vermicompost and irrigation with domestic wastewater

The use of organic solid waste/effluent has currently been increasingly enhanced. A waste and effluent currently produced on a large scale that have potential for use in agriculture refers to sludge tannery and wastewater, respectively. However, in Brazil these residues are still little used and there is great reluctance to use them in general agriculture. Thus, this study aimed to evaluate the characteristics of an...

Sugarcane cultivation submitted to water replacement via irrigation bar

From the hypothesis that during the development of sugarcane, the water regime affects the morphological performance and this affects the productivity. The objective of this work was to evaluate the growth, development, productivity and yield of sugarcane during the cycle the planting sugarcane (variety SP83-5073), under different water replacements. The experiment was established in the Boa Vista mill located in...

Effect of saline water, bovine biofertilizer and potassium on yellow passion fruit growth after planting and on soil salinity

The monitoring of plants growth constitutes an important activity during the crops formation, including the yellow passion fruit. In this direction, an experiment was carried out in Remigio, Paraiba State, Brazil, to evaluate the effects of saline water irrigation, bovine biofertilizer and potassium on yellow passion fruit growth plants and soil salinity. Treatments were arranged in randomized block with three...

Nematicidal effect of Crambe abyssinica leaf extracts to Meloidogyne javanica on tomato

Root-knot nematodes (Meloidogyne javanica) interferes with the production of tomato. The indiscriminate use of chemical nematicides brings negative consequences to society. The aim of this study was to investigate the effect of crambe extract on the control of M. javanica, with different modes and application times, in tomato. Studies were conducted during the 2014 cropping season at the climatized greenhouse located at...

Profit loss per hectare according to profit efficiency level among smallholder rice farmers in Central Liberia

Self-sufficiency in rice production has been an essential issue in the Liberian agriculture sector. With the increasing demand and low national productivity of rice (1.2 t/ha), Liberia remains a net importer of rice unless domestic production improves significantly. This study was conducted to analyze smallholder rice farmers’ level of efficiency and profit-loss due to allocative and technical inefficiencies. A...

Evaluation of morphological aspects of common bean (Phaseolus vulgaris L.) genotypes for post-flowering drought resistance in Rift Valley of Ethiopia

The development of bean varieties adapted to drought situations is a key strategy to minimize crop failure and improve food security. In this study, 25 genotypes of common beans (Phaseolus vulgaris L.) were grown under post flowering drought stress and non-stress conditions to evaluate their performance at Melkassa Agricultural Research Center during the off-season months (from December to May) in 2011/2012. The...
