How does defoliation management impact on yield, canopy forming processes and light interception of lucerne (Medicago sativa L.) crops?
The frequency of defoliation is the major management tool that modulates shoot yield and the accumulation of C and N root reserves in lucerne crops. A fully irrigated, two year old lucerne (Medicago sativa L.) crop was ...
Plant Modelling Framework: software for building and running crop models on the APSIM platform
(Elsevier B.V., 2014-12)
The Plant Modelling Framework (PMF) is a software framework for creating models that represent the plant components of farm system models in the agricultural production system simulator (APSIM). It is the next step in the ...
Sprout development of seed potato tuber after different storage conditions
(Agronomy Society of New Zealand, 2012-11)
Sprout growth and development of 'Fraser' seed potato tubers were quantified after a period of 'Early storage (5-16 weeks from crop defoliation) of tubers in the 'ground', 'shed' or 'cooler' (storage at approximately 4°C) ...
Seed potato physiological age and crop establishment
Seed potato physiological age progressively advances with time (chronological age), but is also influenced by temperature during storage. In this work, different combinations of constant temperatures (2, 8 and 20°C) were ...
Defoliation frequency and season affected radiation use efficiency and dry matter partitioning to roots of lucerne (Medicago sativa L.) crops
Radiation use efficiency (RUE), and subsequent partitioning between shoots and roots were investigated for ‘Grasslands Kaituna’ lucerne crops grown in the cool temperate climate of Canterbury, New Zealand. Crops were ...
Growth and phenological development patterns differ between seedling and regrowth lucerne crops (Medicago sativa L.)
This study compared physiological responses of fully irrigated seedling and regrowth lucerne crops (Medicago sativa L.) grown under similar environmental field conditions. Measurements occurred for 2-4 years after sowing ...
The mechanisms driving potato crop yield and grade distribution
Under ideal growing conditions (e. g. optimal moisture, temperature, mineral nutrition and disease control) potato dry matter (DM) yield increases with the amount of intercepted photosynthetic active radiation (PARi). ...
Physiological age and the mechanisms of crop growth and development of two potato cultivars
(European Association for Potato Research, 2014-07)
In New Zealand, seed potatoes are commonly stored inside sheds at ambient temperature, in low temperature coolers or even left un-lifted in the ground between crop defoliation and harvest. This research describes the ...
LINTUL-POTATO model revisited
(Australian Society of Agronomy, 2017-10)
The LINTUL-POTATO model is revisited in this work. Recent findings on quantification and description of potato crop phenology are incorporated into the original model framework. The results presented in this work may be ...
Growth and root : Shoot dry matter partitioning in seedling lucerne
Sowing date affected shoot and root biomass yield in seedling lucerne. Biomass partitioning to roots was influenced by photoperiod and water stress.
