Ammonium and nitrate levels of soil inoculated with Azospirillum brasilense in maize

Azospirillum brasilense is a nitrogen fixing bacteria used in maize crop production due to its high capacity for plant growth promotion and yield increase. The present study aimed to evaluate ammonium and nitrate levels from soil inoculated with A. brasilense in maize crop production. The experiment was carried out in greenhouse conditions, using randomized blocks with split plots for 20 days with four replicates and...

Carbon sequestration and assessment of fertility status of soil under different land uses for agronomic potentials in Abakaliki South Eastern Nigeria

Abakaliki is predominantly agrarian but continuous cropping is largely practiced due to population pressure. Consequently, there is effort to evolve strategies that would ensure sustainable productivity. This necessitated a research which was carried out to study carbon sequestration and assessment of fertility status of soil for agronomic potentials under different land use systems. Six different land uses each of 20 m...

Selectivity of pre-and post-emergent herbicides for cowpea (Vigna unguiculata)

Historically, cowpea farming has been concentrated to the north and northeast of Brazil, and is usually cultivated with low level of technology. However, in recent years, there has been an increase in the area planted with the crop in the central west, using technology, and there is therefore now a need to study, among other factors, the chemical control of weeds. Two experiments were carried out with the aim of making...

Determinants of Adoption of Improved Technologies in Rice Production in Imo State, Nigeria

In Imo State, an increasing number of improved rice production technologies and management techniques have been introduced to rice farmers across the State. Despite the introduction of the rice production technologies, rice production continues to be low. This study therefore analyzed factors associated with adoption of improved rice production technologies in Imo State of Nigeria. Random sampling technique was used in...

Macronutrient content and accumulations in different arrangements of dwarf pigeon pea intercropped with corn

Intercropping is a technique which consists of cultivating two or more species in the same area. In these systems, planning and management should be carried out in order to avoid interspecies competition for water, light, and nutrients. This paper aimed to evaluate macronutrient content and accumulations in corn (Zea mays L.) intercropped with dwarf pigeon pea (Cajanus cajan L.) in different plant arrangements. The...

The sowing density on oat productivity indicators

The sowing density adjustment in oat can maximize the productivity expression. The aim of this study is to define the behavior of productivity expression of biomass, grains, straw and harvest index through increasing sowing density in the main biotype cultivated in Southern Brazil. It proposes the possibility of indicating higher sowing density to the productivity maximization of biomass and grains. With the density...

Reaction of Coffea canephora clones to the root knot nematode, Meloidogyne incognita

In the Western Amazon, Brazil, Coffea canephora Pierre is the main species cultivated because it has good adaptation to the climate and soils of the region. Among the factors that limit the yield of this crop, Meloidogyne or root-knot nematode, caused by the root knot nematode, is an aggressive disease present in the state of Rondonia. The aim of this study was to evaluate the reaction of fifteen clones of C. canephora,...

Assessment of the performance of informal women entrepreneurs in Enugu State, south east Nigeria

A simple theoretical model of informal women co-operatives micro credit societies’ participation in providing access to credit to informal women entrepreneurs was used to explain their coping strategies under liquidity constraints. A total of 432 questionnaires were administered to informal women entrepreneurs from September 2013 to January, 2014 for primary data collection in Enugu State, south east Nigeria....

Sequential sampling for evaluation of caterpillars, small and large in soybean

Among the main limitations of grain yield in soybean are the insect pests, especially the defoliating caterpillars. It is necessary to reveal and quantify these insects for proper decision-making according to pre-established control levels. So, for the implementation of appropriate management of these soybean insect pests, there is a necessity to establish a sampling plan that will allow an effective, reliable and less...
