We tested the impact of P deficiency, K deficiency, and their interaction on seed alkaloid concentrations and profile, yield and mineral content in sweet (low-alkaloid) and bitter (high-alkaloid) varieties of narrow-leafed lupin (Lupinus angustifolius L.). P deficiency reduced seed alkaloid concentrations in sweet, but not in bitter, varieties. Under P deficiency, the alkaloid profile in harvested seed of sweet varieties mimicked that of the bitter variety Fest, with 13-hydroxylupanine… 
Seed alkaloid concentrations are not affected by agronomic and phosphorus-nutrition treatments that reduce Pleiochaeta setosa Hughes disease on narrow-leafed lupin (Lupinus angustifolius)
The main effects of P nutrition, cereal stubble retention, genotype and crop rotation were significant for the severity of brown spot and plant biomass of narrow-leafed lupin in a field trial in Wongan Hills, Western Australia, but were not significant for total alkaloid concentrations or the relative proportions of individual alkaloids of the harvested seed.
Low alkaloid and higher crude protein contents ofsweet lupins grown in Ethiopia show the possibility to use sweet lupin forage and seeds as cheap home-grown protein source for livestock feed and human food in the country.
Root Morphology, Proton Release, and Carboxylate Exudation in Lupin in Response to Phosphorus Deficiency
Low P supply evidently modified the root morphology by increasing the primary root elongation, and developing a large number of cluster-like first-order lateral roots with dense root hairs, thus allowing efficient P acquisition by narrow-leafed lupin under low P supply.
Effects of growing system and season on the alkaloid content and yield of different sweet L. angustifolius genotypes
Nine varieties and two breeding lines of sweet Lupinus angustifolius were cultivated under organic and conventional conditions in Northern Germany in growing seasons 2010, 2011 and 2012. The alkaloid
The nutritional value of narrow-leafed lupine (Lupinus angustifolius) for fattening pigs
The substitution of soya bean meal by a combination of lupines and RSM reduced the performance of growing and finishing pigs significantly, and the entire replacement of SBM by lupine seeds did not have a negative effect on theperformance of grower and fattener pigs.
Applications of mineral nitrogen increase the yield and content of crude protein in narrow-leaf lupin seeds
In a plant pot experiment with non-inoculated seed stock of narrow-leaf lupin, increasing levels of nitrogen linearly increased the content of crude protein in seeds during harvest from 24.2% to 40.6%, thus increasing the nutritional quality of the seeds.
Elucidating the role of Kelpak® on the growth, phytohormone composition, and phenolic acids in macronutrient-stressed Ceratotheca triloba
We evaluated the role of Kelpak® on growth, nutritional content, phytohormones, and phenolic acids in the angiosperm Ceratotheca triloba (Bernh.) Hook.f. grown under macronutrient-deficient
Development and Validation of a Gene-Targeted dCAPS Marker for Marker-Assisted Selection of Low-Alkaloid Content in Seeds of Narrow-Leafed Lupin (Lupinus angustifolius L.)
The iuc_RAP2-7 marker is considered a powerful tool that will facilitate NLL marker-assisted selection by rapid rejection of bitter Iucundus genotypes and thus accelerate development of new low-alkaloid cultivars.
Effect of genotype and environment on seed quality in sweet narrow-leafed lupin (Lupinus angustifolius L.)
It is indicated that it should be possible to identify genotypes with superior quality from relatively few field trials, and progress in breeding for protein and oil combined will be slowed by the strong negative genotypic correlation between the two traits.
Influence of Nitrogen and Potassium Fertilization on Fruiting and Capsaicin Content in Habanero Pepper (Capsicum chinense Jacq.)
The effect of N or K fertilization on habanero pepper development and fruit pungency was evaluated and nitrogen fertilization significantly increased plant growth and fruit while maintaining high capsaicin levels.


Potassium nutrition effects on seed alkaloid concentrations, yield and mineral content of lupins (Lupinus angustifolius)
The results of glasshouse and field experiments that tested the effect of potassium (K) deficiency on seed alkaloid concentrations highlighted the need for adequate K fertilisation of deficient soils in WA to avoid the risk of producing low quality lupin seed with high alkaloids concentrations.
Interactive effect of cytokinin and potassium on sink-source relationships in Lupinus angustifolius
Increasing K supply interactedpositively with added BAP by increasing narrow-leaf lupin seed yield and harvest index through increases in assimilate supply and its partitioning into seeds.
Varying phosphorus supply and development, growth and seed yield in narrow-leafed lupin
The effects of varying P supply on lupin growth, seed yield and harvest index were examined, indicating that low P supply decreased reproductive growth more than vegetative growth in narrow-leafed l upin.
Effect of Pleiochaeta setosa on field responses of Lupinus angustifolius and L. luteus to applications of phosphorus
The effect of the fungus Pleiochaeta setosa on grain yield responses of lupins to applications of phosphorus (P) fertiliser was measured for 4 lupin cultivars that differed in reaction to the pathogen.
Phosphorus nutrition of spring wheat (Triticum aestivum L.) 1. Effects of phosphorus supply on plant symptoms, yield, components of yield, and plant phosphorus uptake.
Under conditions of acute and moderate P stress, the resources of the wheat plant appear to be directed towards maintaining root growth, limiting and delaying shoot proliferation, and maximising the leaf : stem ratio.
Factors affecting soil acidification under legumes I. Effect of potassium supply
It is suggested that application of K2SO4 does not have a significant impact on acid production by lupin and clover, and total acid production was strongly correlated with total excess cations and total ash alkalinity in plants.
Genetic Influences on the Split Seed Disorder in Lupinus angustifolius L.
The split seed relationship with iucundus and tardus showed differences in expression at one site, which indicated a difference in their mechanism of action at least in the production of severely deformed or shrivelled seed.
Effect of phosphate fertilisers on the elemental composition of seed of wheat, lupin, and triticale
Abstract The effect of phosphorus (P) fertiliser applications applied to the soil on the composition of up to 15 elements (N, P, K, Ca, Mg, S, Cu, Zn, Mo, Mn, Ni, Co, Cd, Fe, and Se) in the seed of
Responses of Rhizobium-inoculated and nitrogen-supplied Phaseolus vulgaris and Vigna unguiculata plants to root volume restriction
It is concluded that dwarfism of RRV plants was not due to water stress, decreased rates of assimilation, increased abscisic acid, sink/source alterations, or to a reduction on the effectiveness of the symbiotic process or of nitrogen uptake in R+ and N+ plants, respectively.
Phosphorus nutrition of spring wheat (Triticum aestivum L.). 4. Calibration of plant phosphorus test criteria from rain-fed field experiments
Five single-year fleld experiments conducted on phosphorus (P) deflcient soils were used to calibrate plant P test criteria for rain-fed, spring wheat, and two consistent trends in relationships between relative shoot yield and P concentrations in whole shoots and leaf blades were observed.
