Media contaming cotton gin trash compost, pear. and perlite were evaluated for production of bell pepper, broccoli, and cabbage transplants. Media treatments were 0:5:5; 1:4:5; 2:4:5; 3:2:5; 4:1:5; and 5:0:5 compost, peat, perlite, respectively (v/v). Separate tests were conducted for each crop. `Jupiter' pepper, `Packman' broccoli, and `Grand Slam' cabbage were seeded in 96-cell plastic trays (cell volume =39cm3). Plant height, stem diameter, and shoot and root dry weight were recorded five weeks after seeding bell pepper and broccoil, and six weeks after seeding cabbage. Pepper, broccoli, and cabbage transplants grown in media containing cotton gin trash compost had greater plant height, stem diameter, and shoot and root dry weight than transplants grown in the medium without compost as a component. The growth response to percent of compost was primarily linear.

A force gauge was used to measure the force required to detach pods from plants of 16 southernpea [Vigna unguiculata (L.) Walp.] cultigens. Pod detachment force (PDF) measurements ranged from 21.4 N for MN-13 to 11.8 N for `Royal Cream'. Pod length, diameter, and weight; basal pod vacancy (inverse of fill); and peduncle synapse length were recorded for each pod sampled for detachment force. There was no strong association between PDF and any of the five traits.

An investigation was conducted in 1993 and 1994 to examine the effect of row spacing on yield and pod maturity distribution of machine-harvested, green-mature southernpeas [Vigna unguiculata (L.) Walp]. `Texas Pinkeye Purple Hull' was planted at row spacings of 53, 89, and 107 cm single drilled and 107 cm double drilled. Marketable yield increased linearly as row spacing decreased. A double drill on a standard 107-cm row spacing did not result in higher yield than a single drill. Marketable yield from the double-drilled, 107-cm row spacing was less than yield from the 53-cm spacing. The seeding rate per hectare for the two treatments was the same. In 1993, the mature pod percentage at harvest increased linearly as row spacing decreased. Row spacings as narrow as 53 cm can be used to increase yield of machine-harvested, green-mature southernpeas.
