Organic matter quality and management effects on enrichment of soil organic matter fractions in contrasting soils in Zimbabwe por Mapfumo, Paul, Mtambanengwe, F., Vanlauwe, Bernard

“…On sandy clay loams, a significant linear relationship between maize yield and the amount of mineralizable N in the macro-POM fraction (R 2 = 0.50; p < 0.01) was evident, while the best predictor for maize yield on coarse sands was the amount of mineralizable N from the organo-mineral fraction (R 2 = 0.86). …”

En jämförelse mellan linjära och traditionella bedömningssystem hos hästar por Hedlund, Susanna

“…The breeding organization for the Swedish Warmblood is today planning a change towards a linear scoring system. The aim of this study was to look at the advantages and disadvantages of using a linear scoring system compared to using a traditional scoring system. …”

Agroforestry practices in the Ethiopian highlands por Berhe, Kahsay, Mohamed-Saleem, M.A.

“…Then the paper outlines and discusses the basic systems in agroforestry including simulataneous agroforestry systems; linear agroforestry systems; alley cropping (hedgerow intercropping); sequential agroforestry systems; shifting cultivation (slash and burn or swidden); improved tree fallow; and Taungya. …”

Effects of weather variability on crop abandonment por Mulungu, Kelvin, Tembo, Gelson

“…In this paper, we examine the influence of soil and climatic factors on crop abandonment using a six-year (2007–2012) panel data by modeling the planted-to-harvested ratio (a good indicator of crop abandonment) using a fractional and linear approach. Therefore, for the first time, our study appropriately (as supported by the model specification tests that favour fractional probit over linear) models the fractional nature of crop abandonment. …”

Adapting the QUEFTS model to predict attainable yields when training data are characterized by imperfect management por Ravensbergen, Arie Pieter Paulus, Chamberlin, Jordan, Craufurd, Peter Q., Shehu, Bello Muhammad, Hijbeek, Renske

“…In this study, we assessed an alternative approach: can the QUEFTS model be adapted to fit smallholder farming systems and associated variation in management? Using 676 observations from the same nutrient omission trials in two major maize production zones in Nigeria, we compare a standard linear regression approach with a quantile regression approach to calibrate QUEFTS. …”

Climate shocks and fertilizer responses: Field-level evidence for rice production in Bangladesh por Takeshima, Hiroyuki, Kishore, Avinash, Kumar, Anjani

“…These findings hold robustly under various fertilizer response function forms, i.e., polynomial function and stochastic Linear Response Plateau. Furthermore, results for stochastic Linear Response Plateau are also consistent for both switching regression type models and Bayesian regression models. …”
