Lettuce is one of the main vegetable species used in organic production. However, studies and research in the organic area are scarce. This study aimed to evaluate the yield and quality of seeds of lettuce genotypes produced in two consecutive years under an organic management system. Two plantations were installed under open field conditions corresponding to autumn/winter in 2016 and 2017. Ten lettuce genotypes were evaluated in four replications using a biofertilizer made from swine manure in the management and manual harvesting of seeds. Evaluations consisted of seed yield (in kg.ha−1), physical test (1000-seed weight), and germination and vigor test (first germination count, germination rate index, and seedling dry matter). The genotype Cubana and two Grand Rapids had higher yields under the tested conditions. Higher seed weights were recorded in 2017. Both genotypes Grand Rapids reached the minimum germination standard established for commercialization (80%). Vanda and AC 5058 showed a better performance for germination rate index and first germination count, while Cinderela had a better seedling dry matter. These varieties were promising for organic cultivation. |

To determine the influence of different restoration methods on litter-dwelling arthropod fauna,
we used pitfall traps to sample in long-term plots subjected to experimental restoration methods
in bottomland hardwood habitat in Sharkey County, MS, USA. For the first 15 yr of the experiment,
treatments included 1) Native ?natural? regeneration (NR); 2) Oak acorns (Quercus nuttallii) directly
seeded (SEED); 3) Oak seedlings planted (PLN); and 4) Oak seedlings interplanted between
the rows of a cottonwood (Populus deltoides) plantation (CW), in a randomized complete block
design. The blocking factor in the experiment reflected differences in elevation which are related
to susceptibility of the different blocks to flooding. After 15 yr (in 2006), the CW plots were
divided into split plots with four additional experimental treatments applied: 1) cottonwoods
clearcut and allowed to resprout to coppice, 2) cottonwoods clearcut and sprouts treated with
herbicide, 3) cottonwoods thinned 50%, and 4) control (cottonwoods left unharvested). Findings
from quarterly (seasonal) sampling one year prior to cottonwood harvest suggested the
collembolan family Sminthuridae was affected by block, but these effects depended upon the
season of sampling. In winter, this group was significantly more abundant in blocks with higher
elevation, whereas in summer the lower-lying block had greater abundance. Other groups
exhibited significant responses to the blocking factor during Summer, including Formicidae,
Entomobryidae, Acari, and Carabidae. In general, these groups were more abundant in the
lower-lying block, possibly indicating moisture dependence in these organisms. The sminthurid
collembolans also had variable responses to the restoration treatments. They were more
abundant in CW plots than in NR plots during the summer sampling, but the opposite pattern
was observed in winter. Other organisms showing restoration treatment effects included three
(Sphecidae, Hemiptera, and Hypogastruridae) significantly more abundant in the CW, and one
(Orthoptera) more abundant in the NR treatment. These results suggest that CW treatments
may foster forest litter-dwelling organisms (and possibly jump-start their associated functions)
in hardwood restorations on the Mississippi Delta. Data from two dates following the
implementation of the cottonwood harvest treatments will also be presented and discussed. MenosTo determine the influence of different restoration methods on litter-dwelling arthropod fauna,
