RESUMO - Realizou-se, no Centro Nacional de Pesquisa de Suínos e Aves - CNPSA, da Empresa Brasileira de Pesquisa Agropecuária - Embrapa, município de Concórdia, SC, no período de novembro a dezembro de 1981, um experimento utilizando o farelo de colza como fonte proteica em ração para frangos de corte, nos níveis de 0, 10, 20 e 30%, em substituição à proteína do farelo de soja. Foram utilizados 736 pintos da linhagem Pilch, de ambos os sexos, do nascimento a 56 dias de idade, utilizando um delineamento experimental, em blocos casualizados, com quatro tratamentos e quatro repetições, tendo, cada um, 46 aves (23 machos e 23 fêmeas). Não houve diferenças significativas (P > 0,05) entre os tratamentos para ganho de peso, consumo de ração e conversão alimentar nos diferentes períodos. Concluiu-se que a proteína do farelo de colza pode substituir ate 30% a do farelo de soja, sem que haja prejuízo no desempenho dos frangos de corte, uma vez que a rações experimentais eram isocalóricas e isoprotéicas. ABSTRACT - A randomized block design, with four treatments and four replications was used to study the rapeseed meal as a source of protein in broilers rations at the Centro Nacional de Pesquisa de Suínos e Aves - CNPSA-EMBRAPA - at Concórdia, SC, Brazil, from November/December 1981. The treatments consisted of replacement of 0, 10, 20 and 30% of the soybean meal protein by rapeseed meal. Each replication was formed by 46 broilers (23 males and 23 females), totalizing 736 Pilch broilers. There were no significative differences (P > 0.05) among experimental rations for daily weight gain, feed intake and feed conversion. It was concluded that the rapeseed meal can replace up to 30% of soybean meal protein without any damage in performance of the broilers, since the rations were isocaloric and isoproteic.

Cassava (Manihot esculenta Crantz) is a vital crop for food and economic security in many regions of the world. Despite the economic and social importance of cassava, challenges persist in developing superior varieties that meet the needs of farmers in terms of agronomic performance, nutritional quality, and resistance to pests and diseases. One of the main obstacles for genetic improvement is the lack of synchronization in flowering and the abortion of young flowers, making planned crosses and progeny production difficult. Therefore, the aim of this study was to evaluate the effect of photoperiod, premature pruning, and growth regulators on cassava flowering under low-altitude conditions in Brazil. Eight cassava clones with contrasting flowering capacity were assessed in Cruz das Almas, Bahia, using two photoperiods (ambient condition and extended photoperiod with red light for 12 hours), premature pruning at the first and second branching levels (with and without pruning), and the application of growth regulators: 0.5 mM 6-benzyladenine (BA) and 4.0 mM silver thiosulfate (STS) (with and without). Plots were assessed weekly for the number of female (NFF) and male (NMF) flowers, height of the first branching (H1B, in cm), number of days to the first branching (ND1B), and the number of branching events up to 240 days after planting (NOB). The extended photoperiod did not promote an increase in the number of flowers but allowed for precocity in cassava flowering, reducing the onset of flowering by up to 35 days, and significantly increasing the number of branches, which is closely related to flowering. The use of pruning and plant growth regulators (PGR) resulted in an increase in NFF from 2.2 (control) to 4.6 and NMF from 8.1 to 21.1 flowers. Therefore, under hot and humid tropical conditions at low altitudes in the Recôncavo of Bahia, manipulating the photoperiod and using premature pruning and plant growth regulators can accelerate cassava flowering, benefiting genetic improvement programs.
