Cowpea is a crop of great importance for small producers in Northeast Brazil, being a source of income and food for family farmers. The present work had as objective to evaluate the productive performance of different cultivars of cowpea in the edaphoclimatic conditions of the city of Barra - BA, region of the Middle São Francisco. The experiment was installed in August 2018 in the experimental field of the Federal University of Western Bahia - UFOB, Multidisciplinary Center of Barra. The cultivars evaluated were: BRS Itaim, BRS Novaera, BRS Paraguaçu, BRS Aracê, BRS Xiquexique, BRS Imponte, BRS Guariba, Pingo de Ouro and CE 25- Semper Verde. The experiment was conducted in a randomized block design, with nine treatments and four replications. No problem with powdery mildew was detected in the cultivars. The cultivar Pingo-de-ouro1-2 showed higher plant height, BRS Xiquexique and CE 25 - Semper Verde larger stem diameter, CE 25 - Semper Verde produced a greater amount of fresh mass from the aerial part and BRS Itaim and CE 25 - Always Green produced the largest amount of dry matter in the aerial part. The cultivars BRS Paraguaçu (80.45%), BRS Xiquexique (79.63%), BRS Guariba (79.60%), Pingo-de-ouro-1-2 (77.98%) and BRS Novaera (76, 78%) had higher grain rates. BRS Itaim produced the highest number of pods per plant, BRS Imponente produced the longest pods, Pingo-de-ouro-1-2 produced the highest number of grains per pod. The cultivar BRS Novaera had the highest weight of a thousand grains. The cultivars BRS Guariba and CE 25 - Semper Verde stood out from the others with the highest levels of productivity, 3,109.50 and 2,863.50 kg ha-1, respectively.

Gherkin is a very consumed vegetable in the North and Northeast of Brazil, and over the years it has been cultivated by the family farmers in a traditional way, with the fruit in contact with the soil, which induces the commercial depreciation of the fruits and the frequent occurrence of diseases. Several techniques have been implemented for the cultivation of fruit vegetables, being the tutoring one of the most used, for promoting the increase of productivity and to improve the quality of the fruits. The objective of this work was to evaluate the productivity of three cultivars of gherkin (North, Northeastern and INPA) in three (undergrowth, in vertical stake and espalier) in the dry and rainy season in Amazonas. Parameters related to weight, length, diameter and number of fruits were evaluated, and productivity was estimated. However, the best quality of the fruits was obtained in the cultivation with espalier. Among the cultivars, INPA presented the best performance. The period of drought was the one that favored the production and quality of the fruits of maxixe, which is recommended for the planting of this crop in the state of Amazonas.
