Other claims from this paper (10)

Observation Sorghum derived 83–90% of phosphorus from fertilizers.
Intervention effect Cattle manure contributed only 20% of nitrogen taken up by sorghum.
Intervention effect Water soluble mineral fertilizers increased soil nitrogen and phosphorus availability.
Intervention effect Water soluble mineral fertilizers yielded the highest total nitrogen uptake by sorghum.
Intervention effect Water soluble mineral fertilizers yielded the highest total phosphorus uptake by sorghum.
Intervention effect Cowpea residues induced microbial nitrogen and phosphorus immobilization.
Intervention effect Cowpea residues reduced sorghum nitrogen and phosphorus uptake to the unfertilized level.
Method / resource Double isotope labeling elucidated fertilizer impacts on soil nutrient pools.
Association Low plant nitrogen to phosphorus ratio suggested nitrogen limitation under manure.

Observation Fertility gradients and fertilizer doses produced variable maize grain yields of 0.99–4.94 t ha−1.
Observation Fertility gradients and fertilizer doses produced variable lentil grain yields of 1.11–2.02 t ha−1.
Association Maize was highly responsive to fertilizer nutrients.
Association Fertilizer N, P and S had a strong direct influence on maize yield.
Association Fertilizer P was the primary variable determining lentil yield.
Intervention effect Sole-fertilizer STCR treatment attained target maize yield.
Intervention effect Integrated STCR treatment attained target maize yield.
Intervention effect STCR treatments missed target lentil yield by 17–29%.
Intervention effect STCR treatments gave lentil a yield advantage over the blanket recommended fertilizer dose.
Recommendation The authors propose integrated STCR targeted-yield management for productivity of the maize-lentil system in tropical-alkaline soils.

Life History Strategies in Linnaea borealis

Mikael Niva KTH Publication Database DiVA (KTH Royal Institute of Technology) 2003

Other claims from this paper (11)

Mechanism The growth of L. borealis ramets is interpreted as not governed by micro-site resource availability.
Intervention effect Removal of light competition increased branching and the number of lateral meristems produced in L. borealis ramets.
Intervention effect Removal of light competition reduced growth of L. borealis ramets.
Intervention effect Removal of light competition decreased the root:shoot ratio per ramet in L. borealis.
Mechanism Apical dominance exerts a significant effect on shoot population fitness in L. borealis.
Observation Apical dominance can be lost through rodent grazing.
Intervention effect If the apical meristem is removed early in the autumn the ramet can repair the loss until the next summer.
Intervention effect If grazing occurs during spring, dry weight and leaf area production are affected negatively.
Observation Seed production in L. borealis in the Abisko area varies between years and sites.
Intervention effect Seed production in L. borealis was unaffected by supplemental hand pollination.
Observation The lack of response to hand pollination implies there is no lack of pollinator activity.
