“…Studies addressing biofertilizer products originating from biological resources such as compost / manure teas and bioinoculants, have shown various benefits for plants. Wang, Radovich, Pant, and Cheng (2014) found that chicken manure-based vermicompost tea suppressed the abundance of plant-parasitic nematodes on zucchini (Cucurbita pepo L.) plants. Vermicompost extract stimulated seed germination, hypocotyl and radicle growth as well as increased chlorophyll content in cannabis (Ievinsh, Vikmane, K , irse, & Karlsons, 2017).…”

The illegal status of cannabis (Cannabis sativa L.) post-World War II resulted in a lack of research on agricultural practices. However, there is a resurgence of interest in cannabis due to diverse uses such as a rich source of cellulosic/woody fiber and construction uses, seed oil, bioenergy and pharmaceutical properties. The principle of an integrated plant nutrition system (IPNS) is to enable adaptation of plant nutrition and soil fertility management to local site characteristics, attempting to optimize use of inorganic, organic and biological resources. This project investigated the individual and combined use of inorganic, organic and biological fertilizer resources on cannabis before and after a period of moderate water stress. We evaluated the individual and combined effects of commercial synthetic fertilizer, humic acid (HA), manure tea and bioinoculant as inorganic, organic and biological resources, respectively on cannabis growth and physiological parameters. Our hypothesis was that the synergetic effects of HA + biofertilizers would improve cannabis growth. When compared to the control, the application of HA and biofertilizer alone, or in combination, increased plant height, chlorophyll content and photosynthetic efficiency by 55, 8 and 12%, respectively, after water stress. Cannabis biomass of treated plants was rarely different from the control. The combined application of HA + biofertilizer resulted in additive, but not synergistic, increases in measured parameter. Future research should focus on the effects of biostimulants on CBD/THC content due to the potential impact on the production of secondary metabolites in plants under stress. 1 INTRODUCTION Cannabis is classified into the family Cannabaceae and has three main types: C. sativa, C. indica, and C. ruderalis (Stearn, 1970) and has various prospective uses in the

“…Previously, reported higher nematode richness in sunn hemp cover cropping compared to bare ground control. Wang et al (2011Wang et al ( , 2014 found that sunn hemp enriched and improved soil food web structure in conservation tillage systems. Higher abundance of fungivorous nematodes in SH at the end of 2013 and throughout the season of 2014 are common occurrences in no-till farming (Hendrix et al, 1986;Kladivko, 2001).…”

In 2013 and 2014, different mulching systems were investigated for their potential to suppress above and below ground pests, and enhance beneficial arthropods and soil health in green onion (Allium cepa) plantings. Three types of mulch systems (organic, living and solarization mulch) were evaluated and compared. Green onions were grown in four pre-plant treatments: 1) organic mulch generated by flail mowing a sunn hemp (Crotalaria juncea) cover crop (SH) followed by a no-till cropping system, 2) soil solarization (Sol), 3) sunn hemp-solarization mulch in which the sunn hemp was incorporated into the soil followed by soil solarization (SHSol), and 4) bare ground with insecticides (BG). Sol, SHSol and BG were practiced in conventional tilled system. SH (in 2013 and 2014) and SHSol (in 2014) treatments included strips of buckwheat and cowpea along the crop border to serve as living mulch or insectary plants. Green onion plants in SH had lower thrips and leaf miners damage than other treatments in both study years. When insectary borders were added to SHSol in 2014, thrips and leaf miners damages were also reduced in SHSol compared to Sol and BG. Incidence of purple blotch was reduced in SH and SHSol treatments in 2014. The SH treatment contained an increased abundance and richness of detritivores, predatory arthropods, parasitoids and beneficial free-living nematodes (particularly bacterivores and fungivores). Although weeds and initial populations of plant-parasitic nematodes were lower in solarization (Sol, SHSol) than other treatments, green onion yield was greatest in SH organic mulch systems in both study years. Overall, the integration of surface organic, living and solarization mulches into a green onion agroecosystem provided multiple ecosystem services including suppression of above and below ground pest organisms.

“…In combining alternative management practices, one study that focused on Hawaii zucchini production evaluated the combination of sunhemp cover cropping and vermi-compost tea amendments, and found improved nitrogen supply, supression of parasitic nematodes, and enhanced bacterivorous nematodes (Wang et al, 2014). In Michigan, the addition of compost and rye cover cropping in a tomato production system did not affect nematode populations, but increased soil microbial biomass, respiration and crop yields (Nair and Ngouajio, 2012).…”
