Broad Mite on Primocane-fruiting Blackberry in Organic Production in Arkansas

The broad mite (Polyphagotarsonemus latus) was found in association with leaf-curling symptoms on primocane-fruiting blackberry (Rubus rubus) in Arkansas in 2007–2009. Broad mite had not been previously reported on blackberry. The plots sampled in this study were part of a study comparing harvesting in the fall versus harvest in spring and fall, high tunnels versus ambient conditions, and three genotypes, all under organic production. Leaves were sampled, broad mites per leaf counted, and leaf area and trichome density measured. Results indicated that broad mite is capable of overwintering in a moderate temperate climate and that it reduces leaf area of primocane-fruiting blackberry. The fall-only harvest system had fewer broad mites than fall and spring harvest. There were a range of genotype effects on broad mite populations, including one genotype, ‘Prime-Jan®’, on which broad mite populations remained low, and one genotype, APF-46, on which mite populations grew significantly. Observations indicate that the broad mite may be a pest of ‘Prime-Ark® 45’, another primocane-fruiting cultivar.

Canopy Model

Abstract A new logical framework relating the structural and functional characteristics of a vegetation canopy is presented, based on the hypothesis that the ratio of leaf area to leaf mass (specific leaf area) varies linearly with overlying leaf area index within the canopy. Measurements of vertical gradients in specific leaf area and leaf carbon:nitrogen ratio for five species (two deciduous and three evergreen) in a temperate climate support this hypothesis. This new logic is combined with a two-leaf (sunlit and shaded) canopy model to arrive at a new canopy integration scheme for use in the land surface component of a climate system model. An inconsistency in the released model radiation code is identified and corrected. Also introduced here is a prognostic canopy model with coupled carbon and nitrogen cycle dynamics. The new scheme is implemented within the Community Land Model and tested in both diagnostic and prognostic canopy modes. The new scheme increases global gross primary production by 66% (from 65 to 108 Pg carbon yr−1) for diagnostic model simulations driven with reanalysis surface weather, with similar results (117 PgC yr−1) for the new prognostic model. Comparison of model predictions to global syntheses of observations shows generally good agreement for net primary productivity (NPP) across a range of vegetation types, with likely underestimation of NPP in tundra and larch communities. Vegetation carbon stocks are higher than observed in forest systems, but the ranking of stocks by vegetation type is accurately captured.

Cherry Tomatoes

The potential market for locally produced organic cherry tomatoes (Solanum lycopersicum var. cerasiforme) is large in Canada, but it is challenging to grow this warm-season crop in open fields (OFs) due to the cool and short growing season. To test the feasibility of using high tunnels (HTs) for improving organic production in southern Ontario, plant growth, fruit yield and quality, and pest and disease incidence were compared for ‘Sarina hybrid’ cherry tomato among three production systems: OF, HT, and high tunnel with anti-insect netting (HTN) in Guelph, ON, in 2015 and 2016. Averaged over the 2 yr, the highest marketable fruit yield was achieved in HT (≈70 t ha−1), followed by HTN (≈50 t ha−1), with the lowest yield obtained in OF (≈24 t ha−1). Compared with OF, increased plant growth, extended harvest period, reduced pest numbers, and increased proportion of marketable fruits all led to the higher marketable yields in HT and HTN. Under HT vs. OF, fruit quality attributes, such as soluble solids content and post-harvest water loss, were better in 2015 and similar in 2016. Although the insect netting reduced pest incidence and disease infection, fruits harvested from HTN had lower yield, smaller size, and lower soluble solids content than those from HT in both years. Therefore, HT can be recommended for organic production of cherry tomatoes in southern Ontario.
