“…On the other hand, the lowest RY was observed for genotypes 1 (16.63 t ha -1 ) and 12 (15.38 t ha -1 ). Previous studies also observed a positive correlation between RY and number of roots per plant (Rós and São João 2016, Tumuhimbise et al 2015.…”

The morphoagronomic characterization of 12 genotypes of M. esculenta was performed during the 2013/2014 and 2014/2015 crop years. The 12 genotypes were planted in a randomized block design, with four replicates per genotype. Number of tuberous roots per plant, weight of tuberous roots, root yield, total plant weight, harvest index, plant height, height of first branch, number of shoots, stem diameter, number of buds, leaf dry weight and petiole length were evaluated. Genotypes "Camuquem" and "Goiás" were the most productive, and "Amarela" and "Gema de Ovo" were the most divergent. Seventy percent of genetic diversity was due to petiole length (22.86%), root yield (19.20%), weight of tuberous roots (14.89%) and number of buds (13.72%). Overall, the present results indicate a broad genetic basis for the evaluated genotypes, so that such genetic variation benefits the plant breeding for future scenarios Further studies of the evaluated genotypes should be performed under environmental limitations, using biochemical and molecular tools to identify markers for genetic improvement.

“…Donato et al (2020) observaram menores produções de raízes de batata-doce conduzido somente em sistema solteiro com média de 16,6 ton ha -1 . São João (2016), constataram que em consórcio de batata-doce e mandioca, a batata-doce apresenta maior produção de raízes quando em sistema solteiro. Nespoli et al (2017) observaram que durante o consórcio de alface + milho verde, que a cultura da alface produz mais quando solteira, e que a produção de milho verde não é influenciada pelo consórcio.…”

O objetivo foi avaliar o crescimento das plantas, produção de raízes de batata-doce (Ipomoea batatas) e grãos de milho pipoca (Zea mays) em sistema de cultivo solteiro e consorciado. Foram avaliadas quatro cultivares de batata-doce e uma de pipoca em blocos casualizados com três repetições em condições de campo. No cultivo solteiro, a pipoca e batata-doce foram espaçadas 75 cm entre linhas. No consorciado, o plantio da batata-doce foi no centro das entre linhas da pipoca. A adubação foi realizada com cama de frango. Aos 30, 60 e 90 dias foi avaliado o número de folhas, altura das plantas, diâmetro do colmo/baraços e comprimento de baraços. No florescimento foi determinada a matéria seca das plantas, na maturação fisiológica a produção de grãos da pipoca e aos 180, as raízes da batata-doce. Observou-se que a pipoca apresentou a maior produção de matéria seca, número de folhas, diâmetro de colmos e altura de plantas quando solteiro, as cultivares de batata-doce quando consorciadas menor produção de matéria seca e raízes, a produção de grãos de pipoca não apresentou diferença entres os sistemas de produção. O sistema consorciado de pipoca e batata-doce promove maior produção de matéria seca e produção de alimentos por área.

Intercropped cultivation of sweet potatoes and popcorn: growth and production of crops ABSTRACT: The objective was to evaluate plant growth, sweet potato productivity (Ipomoea batatas) and grains of popcorn (Zea mays) in single and intercropped systems. Four sweet potato cultivars and one popcorn in randomized blocks were evaluated with three replications in field conditions. In single cultivation, popcorn and sweet potatoes were spaced 75 cm between rows. In the intercropped, the sweet potato was in the center of between the lines of popcorn. Fertilization was carried out with chicken manure. At 30, 60 and 90 days, the number of leaves, plant height, stem/tiller diameter and tether length were evaluated. At flowering, the dry matter of the plants was determined, at physiological maturity the grain yield of the popcorn and at 180, the roots of the sweet potato. It was observed that the popcorn showed the highest production of dry matter, number of leaves, stem diameter and plant height when single, sweet potato cultivars when intercropped, lower production of dry matter and roots, the productivity of popcorn grains there was no difference between the production systems. The intercroped system of popcorn and sweet potatoes promotes greater production of dry matter and food productivity per area. Keywords: polyculture; sustainability; family farming; Ipomoea batatas; Zea mays.

The global production of arrowroot is minimal, and this may be partially associated to the lack of standardized agronomic techniques for its commercial cultivation. This study aimed to assess the yield and profitability of arrowroot plants (‘Comum’ cultivar) grown using different plant spacings in the cropping row (20 cm, 25 cm, 30 cm and 35 cm) and a varying number of hilling applications (0, 1 and 2). The treatments were arranged in a 4 x 3 factorial scheme, in a randomized experimental block design, with six replications. After harvesting, the fresh and dry matter yields of leaves, rhizomes and roots were determined. Production costs and gross and net incomes were also calculated. The highest yields for fresh leaves (8.75 t ha-1), rhizomes (32.92 t ha-1) and roots (8.45 t ha-1) were obtained with a plant spacing of 20 cm. No interaction between the factors, neither significant differences for the use or not of hilling, were observed on the analyzed variables. The costs per hectare ranged from BRL 8,488.83 (35 cm without hilling) to BRL 10,376.23 (20 cm with two hillings). The highest yields and gross and net incomes were obtained with the spacing of 20 cm between plants.
