  1. Interaction of small-scale supplemental irrigation, <em>sawah</em> preparation intensity and soil amendment type on productivity of lowland <em>sawah</em>-rice system

    Interaction of small-scale supplemental irrigation, <em>sawah</em> preparation intensity and soil amendment type on productivity of lowland <em>sawah</em>-rice system

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Sole dependence on rainfall, poor water management and low soil fertility largely explain the fluctuations in agricultural productivity in West Africa. Lowlands for sawah-based rice farming often offer opportunities for small-scale supplemental irrigation but these are rarely explored and their...
  2. A Γ-Whitehead product for track groups and its dual

    A Γ-Whitehead product for track groups and its dual

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we generalize the product defined by Hardie and Jansen in [3]. The generalized product gives a pairing [·, ·] W Γ : [ΓX ∧ W, Z] × [ΓY ∧ W, Z] → [Γ(X ∧ Y)...
