Among the main factors affecting the pea culture, are the incorrect use of fertilizers and unimproved cultivars. However, studies using appropriate and nitrogen levels are deficient, being necessary to carry out further research. This study aims to evaluate the effect of nitrogen in the production of pea cultivars. The experimental design was a randomized complete block in a factorial 2 x 5, with four replications. Cultivars were evaluated: 'Canoa' and 'Petit Pois'; and five doses of N (0; 50; 100; 150 and 200 kg ha -1 ). We used the conventional planting system for producing dried pea grains. The N rates were applied 30 days after sowing. The following characteristics were evaluated: N foliar content, plant height, stem diameter, number of pods per plant, pod length, pod diameter, grain diameter, number of grains per pod, number of grains per plant, weight 100 grains, dry matter of shoot and grain yield. 'Petit Pois' was superior to cultivate Canoa in most components of production, mainly in grain yield. Nitrogen rates increment the number of pods per plant, pod length, number of grains per plant and grain yield.

RESUMOA otimização do espaço na produção de hortaliças é de suma importância para o agricultor; algumas vezes esse é o limiar do lucro. Novos arranjos de plantas com disposições diferentes buscam maximizar a produção. Objetivou-se com este trabalho avaliar a produtividade de ervilha de vagens comestíveis em diferentes densidades de plantio, variando o espaçamento entre covas e o número de plantas por cova. O delineamento experimental utilizado foi de blocos ao acaso, com oito tratamentos no esquema fatorial 4 x 2 (espaçamentos entre covas de 0,2; 0,3; 0,4 e 0,5 m com 1 ou 2 plantas por cova), representando densidades de 20.000 a 100.000 plantas/ha para o espaçamento de 1,0 m entre linhas, com seis repetições. Foram avaliadas a produtividade total e comercial, a produção de vagens comerciais por planta e o número de vagens comerciais. Os dados foram submetidos ao teste F, sendo as médias referentes ao número de plantas por cova comparadas pelo teste de Tukey e as referentes aos espaçamentos pela análise de regressão. Foi obtida maior produtividade de vagens comerciais (15,53 t/ha com 2 plantas por cova) e menor produção por planta (150 g com 2 plantas por cova), quanto menor o espaçamento (0,2 m). Caso o produtor resolva plantar com um espaçamento maior, aconselha-se o uso de duas plantas por cova. Palavras-chave:Pisum sativum, produtividade, espaçamento. ABSTRACT Plant density in the production of edible pod peaThe optimization of space in vegetable production is very important to the farmer; sometimes this is the threshold of profit. New arrangements of plants with different provisions seek to maximize production. The objective of this research was to evaluate the productivity of edible pea pods in different planting densities, varying the spacing between holes and the number of plants per hole. The experimental design was randomized blocks, with eight treatments in a factorial scheme 4 x 2 (spacing among holes of 0.2, 0.3, 0.4 and 0.5 m with 1 or 2 plants per hole), representing densities of 20,000 to 100,000 plants/ha for spacing of 1.0 m between rows, with six replications. We evaluated the total production/ha, the marketable production/ha and per plant, and the number of marketable pods/ha and per plant. The data were submitted to the F test, and the means concerning number of plants per hole were compared by Tukey's test and the spacing between holes by regression analysis. Higher productivity was obtained (15.53 t/ha with 2 plants per hole) and lower production of pods per plant (150 g, with 2 plants per hole), the smaller the spacing (0.2 m). However, if the farmer decides to plant on greater spacing, the density of two plants per hole is recommended.
