amendments such as compost and manure have also been shown to be a good source of fertilization in container-grown organic plant production ( Raviv et al., 2005 ). Plant- and animal-based fertilizers have previously been tested in the production of vegetable
obtained from the nursery (they came from the nursery in a 1-L plastic bag) and had been fertilized previously with Basacote ® Plus 3M (2 g/L substratum) on one occasion. They were selected from 120 saplings for assay and the selection was based on the
Hettiarachchi 2019 ). Deciduous fruit and nut tree responses to P fertilization have been mixed, especially in established orchards of crop-bearing age. Leaves displaying P deficiency symptoms were rare in commercial orchards ( Brown and Uriu 1996 ; Cullinan
with organic fertilizers, whereas bulb yields and soluble solids were similar between organic fertilizers and synthetic inorganic fertilizers ( Lee, 2010 ). The objective of this study was to evaluate the effects of organic fertilization rate on sweet
% PTS to increase as peat amendment increased when fertilized with 50, 100, and 200 mg·L −1 N. When plants were fertilized with 300 mg·L −1 N, shoot dry weight of plants grown in at least 40% PTS (by volume) with the remainder being peat, did not
postharvest factors that may affect lettuce phenolics have not been well studied. The aim of this study was to evaluate the effects of cultivar, organic fertilization, and high tunnel production on the phenolic constituents of lettuce. Individual phenolic

micropropagation for the genus Cohniella . In this study, we examined the possibility of storing C. cepula pollinia at 4, −20, −70, and −196 °C. Pollen viability was evaluated by their fertilizing ability, fruit and seed formation, seed viability, in vitro seed

the specific N requirements of growing plants ( Line et al., 2002 ). Both homeowners and landscape professionals can contribute to the improvement of water quality by fertilizing landscapes at the minimum required levels for healthy, attractive plants
