“…Synergy between water supply and organic fertilization occupies interest of both growers and scientistswho try always to reach best combined effect. Level of research on Roselle does not live up to the works done on its closely related species, such as cotton or cannabis (Kumar et al, 1986).…”

H IBISCUS sabdariffa L. (Roselle) isaherbal medicineplant that has severaluses, i.e. as a food or a flavouring agent in the food industry, and also in hot and cold beverages. It is a cash crop in arid and semi-arid zones. The experiment was conducted to study the effect of irrigation and compost applicationon Roselle in Rasheed, Egypt. Water supplyfrequency was divided into three different timingsin 2, 4 and 6 days intervals. In addition to mineral fertilizers, soil media were supported with compost as a soil amendment at 5, 10 and 15 t fed-1. The positive effect of irrigation and compost application was monitored on plant height, stem diameter, number of leaves, branches and fruits, dry weight of plantand calyx. Leaf chlorophyll contents and calyx anthocyanin composition were positively increased with the increase in interval and compost application.

“…Little is known about its genetic potential, divergence and variability, which are supposed to be large when considering its wide geographical distribution. The level of research on Roselle does not compare to the works done on its closely related species, such as cotton (Kumar et al, 1986). Most breeding of Roselle has been for its fiber yield.…”

Landraces of vegetable Roselle (Hibiscus sabdariffa var. sabdariffa L.) are under subsistence and commercial cultivation in tribal, rural and peri-urban vegetable farming systems by the tribal folks, small and marginal farmers of south India. Leaf yields of these landraces are low in farmer's conditions either due to poor production potential of landraces or poor agrotechniques. The production potential and the economic value can be enhanced by identifying the promising landraces and their intensive cultivation in the market and truck gardens. In collaboration with National Bureau of Plant Genetic Resources, Regional Station, Rajendranagar, 28 landraces of vegetable Roselle were collected from parts of Andhra Pradesh and Odisha states of India during 2010-2011. These landraces were evaluated in a randomized block design with three replications during summer 2013 at Vegetable Research Station, Rajendranagar to assess the production potential and the genetic variability for various agro-economic traits. The variation recorded within the landrace germplasm for plant height, total biomass, leaf yield, stalk yield, leaf-stalk ratio and harvest index show its potential for use in the genetic improvement. The landraces RNR-16, RNR-20 and RNR-27 were promising as indicated by the high leaf production potential of 14.22, 12.72 and 11.85 g plant-1 , respectively. High estimates of heritability coupled with high genetic advance as percent of mean for plant height, total biomass, leaf yield, stalk yield and leaf-stalk ratio indicating the possibility to improve these agro-economic traits through selection programs. Selection is effective for plant height, leaf yield, stalk yield, leaf-stalk ratio and total biomass in vegetable Roselle.

“…It is also widely grown in Kogi, Kwara, Kebbi, Sokoto, Zamfara, Katsina, Borno, Kaduna, Bauchi and Kano States (Dike, 1987;Alegbejo, 1998). Inspite of its economic importance and the fact that the crop originated in West Africa, not much research work has been conducted on it when viewed in relation to the amount of work undertaken on its closely related species, such as cotton (Kumar et al, 1986;Dike, 1987). Relatively little has been reported on the agronomy of roselle in northern Nigeria.…”

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.
