Combined effects of provenance and slow-release fertilizer on nursery and field performance of yellowhorn seedlings

Abstract

Yellowhorn ( Bunge) has been widely planted for biodiesel production in China, but has frequently shown poor field performance. Container-grown yellowhorn seedlings originating from three Chinese provenances, Wengniute Qi (WQ), Alukeerqin Qi (AQ), and Shanxian (SX), were fertilized with slow-release fertilizer (SRF) at 40, 80, 120, 160 or 200 mg N seedling. Tree growth, survival and nutrient content were measured after one year’s growth in a greenhouse followed by two years in a field site. Plants from AQ and SX tended to have higher stem and root P contents in the nursery. Higher rates of SRF increased root N, and stem and root P contents. After one year in the nursery, there were a number of interactions between provenance and SRF for plant growth responses and nutrient content in the nursery, however after two years of additional growth in the field, plants from the different provenances generally responded similarly to applied SRF in the nursery, with few interactions. Final plant height was approximately 10% lower in trees from provenance SX but was not affected by application of SRF. Conversely, final trunk diameter and stem and root biomass were unaffected by provenance but increased with higher rates of applied SRF. Our results indicate that application of SRF may be a useful tool to nutrient load yellowhorn in the nursery and facilitate transplanting performance in the field. Overall, optimal nursery and field performance of yellowhorn were observed in provenance AQ at 120–200 mg N seedling SRF. We suggest that growers consider a wider range of yellowhorn provenances and SRF rates (above 200 mg N seedling) to yield even better growth response.Xanthoceras sorbifolium–1–1–1

Combined effects of provenance and NPK-fertilizer on nursery performance of kelor (Moringa oleifera) seedlings

“…This condition indicated that P2 was more responsive in diameter growth to the addition of a dose of NPK fertilizer compared to P1. According to [20], a significant interaction between provenance and NPK fertilization occurred in the N content of the Yellowhorn stem (Xanthoceras sorbifolium Bunge). The addition of NPK fertilization doses also increased the P content of the root and stem of the seedling significantly.…”

Container volume and doses of maximum technical efficiency of controlled-release fertilizer on the morphological quality of Cordia alliodora seedlings in Roraima

“…Controlledrelease fertilizers (CRF) have been described as an alternative to conventional fertilizers for fertilization of seedlings in the nursery phase, because they induce rapid initial growth (Wang et al, 2016;AO et al, 2018;Shi et al, 2019) and favor sur vival and vigor after the field planting phase (Fu et al, 2017;Shi et al, 2019). Currently, research has shown a positive effect of controlledrelease fertiliz ers on the production of native seedlings in northern Brazil.…”

Nutritional status and biomass of african mahogany seedlings grown with nutrient solution in the Northern Amazon

“…However, researchers have also shown the strong positive relationship between increased nutrient reserves in plants fertilized with nutrient solution and survival and vigor after transplanting the seedlings into the field (SHI et al, 2019), even in adverse edaphoclimatic conditions and limiting factors (AO et al, 2018), a reflex is attributed to the accumulation of nutrients in the nursery phase, which would represent an advantage to growth in the postplanting period.…”
