Abstract

Soil organic carbon (SOC) and total soil nitrogen (TSN) dynamics have both pedological and agronomic basis. Knowledge of their retention within aggregate hierarchies of varying soil textures as influenced by land use change is limited. The capacity of loam (L), clay loam (CL), sandy loam (SL) and sandy clay loam (SCL) soils to retain SOC and TSN in water-stable aggregate (WSA) at 10-cm intervals of 0-30 cm topsoil depths under cultivated and bushfallow/ uncultivated systems was investigated.

Abstract 

This study adopted a content analysis to describe the prominence given to agricultural information in print media using four selected Newspapers.  Specifically, the study determined the space allotted; the number; and prominence given to agricultural information in Nigerian newspapers. Stratified  and purposive sampling procedures were used to select a sample of 384 editions of newspapers for analysis. Data were collected from hard copies of the  selected Newspapers and were analysed using percentages, Kruskal Wallis (H) test and Pearson Product Moment correlation.

The study assessed the determinants of communication channel use among rice value chain actors in Nasarawa and Benue States, Nigeria. A multistage  sampling procedure was used to select six hundred (600) respondents. Data were collected using a semi-structured interview schedule and were  analyzed using a binary logistic regression model with the forced entry method.

The study assessed perceived factors influencing farmers’ preference for rice varieties grown in Enugu State, Nigeria. A structured interview schedule was used to obtain information from 150 rice farmers. Data collected were analysed using frequency counts and percentages. The major rice varieties grown by the farmers were Faro 44 (60.7%), R8 (28.7%) and Mass II (20.7%).

We use rich survey data to investigate the economic impact of a climate-friendly rice farming method known as the system of rice intensification (SRI) on the welfare of rain-dependent small-holder farmers in Tanzania. SRI reduces water consumption by half, which makes it a promising farming system in the adaptation to climate change in moisture-constrained areas, and it does not require flooding of rice fields, resulting in reduced methane emissions.

AbstractThis article contributes to a growing body of empirical literature relating credit constraints and incomplete insurance to investment decisions. We use panel data from rural Ethiopia to investigate whether participation in a safety net program enhances fertilizer adoption. Using a difference‐in‐differences estimator and inverse propensity score weighting, we find that participation in Ethiopia's food‐for‐work (FFW) program increased fertilizer adoption in the short run, but not in the long run.
