“…[29] obtained the highest dry calyx yield of red variant roselle with 60 kg N/ha at Bauchi, Nigeria. The positive response of dry calyx yield of roselle to nitrogen obtained is in conformity with the findings of [30] and [31] who reported that nitrogen fertilizer increased calyx yield of roselle. Similarly, [32] reported increased calyx with nitrogen application.…”

Field experiments were carried out on roselle (Hibiscus sabdariffa L) during the 2019 and 2020 cropping seasons at the CSIR-SARI Research Station at Manga in the Upper East Region of Ghana. The aim of the experiment was to study the response of roselle to cowdung, nitrogen fertilizer and their interaction on the growth and yield of roselle. The treatments consisted of factorial combination of five rates of cowdung (0, 1.5, 2.5, 3.5 and 4.5 t/ha) and five levels of nitrogen (0, 20, 40, 60 and 80 kgN/ha) laid out in a randomized complete block design and replicated three times. Data were collected on days to 50% flowering, plant height, number of leaves per plant and dry calyx yield. The results indicated that differences in dry calyx yield due to the manure and nitrogen fertilizer effects were highly significant (P < 0.01). Application rate of 2.5 t/ha manure recorded the highest yield of 340 kg/ha and 308.1 kg/ha in 2019 and 2020 respectively. Increasing manure rate from 2.5 -3.5 t/ha did not result in significant increases in dry calyx yield. The four rates differed significantly from the control which had the least calyx yield of 190.3 kg/ha and 180 kg/ha in 2019 and 2020 respectively. Nitrogen rate of 60 kg/ha recorded the highest dry calyx yield of 510.5 kg/ha and 370.4 kg/ha in 2019 and 2020 respectively which were significantly different from calyx yields recorded by other treatments. The trend on partial budget analysis was consistent in both seasons with the highest yielding treatments (2.5 t/ha cowdung manure and 60 kg/ha) recording the highest net benefit while the control

“…The calyx is the part of greatest interest, for fresh or dehydrated, they are utilized in teas or refreshments of special flavor and taste (TESKE and TRENTINI, 1995), as well as jams (GAMAL et al, 1984), liqueurs, vines, syrups, ice-creams, sauces, pies, vinaigrettes, desserts, dyes and flavorers (SAMBAMURTHY, 1953).…”

The objective of this work was to evaluate the yield of calyxes of Hibiscus sabdariffa L, a medicinal plant, at four planting times in Lavras MG. The treatments were four planting times ( th 2002) and a harvest was proceeded when practically there were no developing calyxes, almost at the end of the plant cycle. The numbers of calyxes per plant, the fresh and dry biomasses of calyxes and quality were taken into account. It follows that planting time influenced yield per plant and the fresh and dry biomasses of calyxes, differing from each other by Tukey test at 5%. In October planting, there was a higher yield (2,522kg/ha) with a yield 5.24 as high relative to the planting of the month of January (481 kg/ha). The planting s in the month of November to December showed yields of 1,695 and 1,093 kg/ha of dry calyxes, respectively and in relation to the same months of January, yield was of 3.52 to 2.27 times more. Harvest must be done as soon as the calyxes are ripe in order to preserve quality.Index Terms: Organic farming, calyx, medicinal plant, yield, vinegar plant. RESUMOObjetivou-se avaliar a produtividade de cálices de Hibiscus sabdariffa L., planta medicinal, em quatro épocas de plantio em Lavras M.G. Os tratamentos foram quatro épocas de plantio (18 de outubro; 15 de novembro; 18 de dezembro de 2001 e 15 de janeiro de 2002) e realizada uma colheita quando praticamente não existiam cálices em desenvolvimento, quase no final do ciclo da planta. Foram considerados os números de cálices por planta, as fitomassas frescas e secas dos cálices e a qualidade. Concluiu-se que a época de plantio influenciou o rendimento por planta e as fitomassas frescas e secas dos cálices, diferindo entre si pelo teste de Tukey a 5%. No plantio de outubro, houve maior rendimento (2.522 kg/ha), com produção de 5,24 vezes a mais em relação ao plantio do mês de janeiro (481 kg/ha). Os plantios nos meses de novembro e dezembro tiveram produções de 1.695 e 1.093 kg.ha -1 de cálices secos, respectivamente, e em relação ao mês de janeiro, a produção foi 3,52 e 2,27 vezes a mais. Deve-se realizar a colheita assim que os cálices estiverem maduros, a fim de preservar a qualidade.Termos para indexação: Agricultura orgânica, cálice, planta medicinal, produtividade, vinagreira.

ABSTRACT:Field experiments were conducted during 1998 and 1999 rainy seasons at the Dry Land Teaching and Research Farm of Usmanu Danfodiyo University, Sokoto, to study the response of roselle to farmyard manure, nitrogen and their interaction on the growth and yield of roselle. Treatment consisted of factorial combination of four rates of farmyard manure (0, 2.5, 5.0 and 7.5 t/ha) and four levels of nitrogen fertiliser (0, 25, 50 and 75 kg N/ha) laid out in a randomized complete block design replicated three times. The result showed that there was significant response to applied manure and N-fertiliser on number of leaves up to 5 t/ha manure and 50 kg N/ha. There was no significant increase in calyx yield by raising manure rate from 2.5-7.5 /ha or nitrogen rate from 50 to 75 kg N/ha. Thus, 2.5 t/ha manure and 50 kg N/ha were considered adequate for calyx production in roselle in Sokoto Semi-arid Tropics. However, for maximum number of vegetable leaves additional manure (5-7.5 t/ha) and N fertilizer (50-75 kg N/ha) may be necessary.
