The gboma eggplant, Solanum macrocarpon , belongs to the subgenus Leptostemonum , section Melongena, and series Macrocarpon . It was domesticated in Africa from the wild savanna species S. dasyphyllum ( Lester et al., 1990 ). The leaves of S

Halosulfuron is an alternative to methyl bromide for managing nutsedges (Cyperus spp.) in several vegetable crops. Field studies were conducted to evaluate eggplant growth and yield when halosulfuron was applied through drip-irrigation before transplant at four rates (0, 26, 39, or 52 g·ha–1 a.i.) or following transplant (26 g·ha–1 applied 1, 2, or 3 weeks after transplant) in spring and fall crops in 2002 and 2003. Inverse linear relationships were observed between rate of halosulfuron and eggplant growth and rate of halosulfuron and eggplant yield. Halosulfuron at 52 g·ha–1 reduced eggplant growth (crop height and canopy width) 19% to 22%. Eggplant fruit biomass at the first harvest was reduced 37% to 63% by halosulfuron applied before transplant. Eggplant was capable of recovering from the initial injury and there was no effect of halosulfuron rate on fruit biomass at the final harvest. Total season fruit biomass was reduced ≤4% from halosulfuron at 39 g·ha–1, while halosulfuron at 52 g·ha–1 reduced fruit biomass 33%. Delay in application of halosulfuron to 3 weeks after transplant (WAT) resulted in ≤7% reduction in fruit biomass and number for the entire season. When halosulfuron was applied 1 WAT, fruit biomass at the first two harvests was reduced >33%, however total season harvest from this treatment was >99% of the yield from the nontreated control. This preliminary study indicates that halosulfuron injected through drip tape may have the potential to assist in the replacement of methyl bromide for nutsedge management in eggplant. However, there are many issues that must be addressed and studied before adopting this practice in eggplant.

Eggplant cultivars comprise one of the most diverse botanical groups in world foodcrop agriculture. Their dietary origins are in China, Japan, Thailand, Africa and Europe. Over the last 60 years in the United States, eggplant has transitioned from a minor ethnic crop into a major vegetable commodity. Four years of horticultural studies in New Jersey have compared 33 worldwide cultivars. Eggplant cultivars included: Asian types—Long Purple, Millionaire, Machiaw, Orient Charm, Bride, Pingtung Long, Ichiban, Thai Round Green, Thai Long Green, and Thai Hard Skin; Indian types—Kermit, Bharta, and Pushpa; African types—Bitterballs, Kinalia, Kinalia XL, and Gangan; European types—Megal, Red Egg, Bambino, Cloud Nine, Rosa Bianca, Comprido Verde Claro; and New York; and several Russian types. These studies utilized raised beds and black plastic with drip irrigation at 30' spacing between plants and five to six feet between single row beds. Two replications were used in initial screening surveys and with four replications for in-depth studies of superior candidates. Over 4 years, the sites were planted from June 5 to 20 June. Harvests began in mid-July and ended in mid-October. The selected eggplant cultivars all exhibited typical bi-modal bearing throughout the season in growth zones 7 and 8. Individual fruit weights ranged from 2.6 to 13.4 oz per fruit. Fruit length ranged from 2.3 to 10.7 inches. Basic fruit colors were white, red, green, purple, and black with several types having variegation and striping. Yields differed significantly among varieties and ranged from 10,000 to 40,000 pounds per acre over the course of the season with multiple harvests. Marketable yields ranged from 2,750 to 8,750 boxes per acre (30 pound boxes).

The effectiveness of varying rates and timing of applied primary plant nutrients as a completely soluble N-P-K fertilizer through a drip/trickle low volume irrigation system was studied during 1991 on eggplant (Solanum melongena cv. Harris Special Hibush). Before the drip irrigation tubing and black plastic mulch were laid on a coastal plain sandy loam soil, plots were treated with 0, 22, 45, and 67 kg ha-1 of nitrogen (N), phosphate (P2O5) and potash (K20). The higher rates of preplant fertilization did have a significant beneficial effect on total seasonal yields of quality eggplants. The preplant treatments also had an influence on mid and late season production. As the frequency of drip/trickle applied primary plant nutrients increased up to 6 seasonal applications, the total quality fruit production substantially increased. Frequency of applications also had an influence on seasonal yields. Applying increased rates of the primary plant nutrients at a low seasonal frequency of 3 applications had little influence on increasing total quality yields of eggplants. Individual quality fruit was significantly heavier from plants which received 5 to 6 applications of the soluble N-P-K fertilizer than from plants which received no fertilizer through the drip/trickle irrigation system for the season.

Eggplant, also known as aubergine and brinjal, is widely grown and consumed in southern and southeast Asia and has increased in popularity in the United States as a specialty vegetable. In 2001, U.S. eggplant production was valued at $42.5 million
