TL;DR: An examination of the production conditions indicated that the dry season is a better period for seed production and the application of organic manure as well as wider between plant spacing than that intended for leaf production favour higher seed yields.
Abstract: Sixteen Corchorus olitorius accessions were field evaluated to provide basic information on seed production. Dry seed yields per plant ranged from 9.8g to 235.0g among 15 accessions grown during the dry season (November 1980February 1981) in contrast to 2.6g produced by a commercial cultivar (oniyaya) in the previous rainy season (March -May 1980). An examination of the production conditions indicated that the dry season is a better period for seed production. The application of organic manure as well as wider between plant spacing than that intended for leaf production favour higher seed yields. Finally, the cost of seed production in relation to the value of seed production is discussed.

TL;DR: A field experiment focusing on the response of Tossa jute to salt stress at germination and vegetative growth stages showed that germinating rate after 24 hrs exceeded 50% under salt levels between 0 and 5 g, and salt stress levels delayed the initiation process and decreased significantly kinetics and rate of germination.
Abstract: A field experiment focusing on the response of Tossa jute (Corchorus olitorius L.) to salt stress at germination and vegetative growth stages was held in the Institute of Arid Lands of Medenine, Tunisia. Results showed that germinating rate after 24 hrs exceeded 50% under salt levels between 0 and 5 g.l-1. Indeed, salt stress levels delayed the initiation process and decreased significantly kinetics and rate of germination, which were severely limited at 9 and 10 g.l-1 NaCl. After one month of growth, Tossa jute seedlings were subjected to salt treatments of 2, 4, 6, and 8 g.l-1 NaCl. After four weeks of stress in pots, morphological responses were reflected by a significant decrease in parameters of growth and yield when salinity reached 8 g.l-1. Indeed, a reduction in the photosynthetic gaseous exchange and a stomata resistance were notified for seedlings subjected to 6 and 8 g.l-1 NaCl treatments. However, in order to tolerate the highest levels of salt, Tossa jute seedlings make different strategies by reducing the size of leaves, which increases their accumulation of osmolytes such as proline (3.1 mg.g-1 DM) and soluble sugars (13.22 μg.g-1 FM) to permitting the osmotic adjustment.

TL;DR: The result of this investigation suggested that green biomass weight, plant height, basal diameter and days to 50% flowering would be the selection parameters to produce jute varieties with acceptable yield.
Abstract: Fifty two accessions of tossa jute germplasm were evaluated for variability. The highest heritability (h2), genotypic coefficient of variation (GCV) and percent genetic advance over mean were observed for the traits green biomass and fibre weight per plant indicated preponderance of additive gene action. Green biomass weight per plant found to be highest (0.85) genotypic correlation with fibre yield per plant. The traits plant height, base diameter, green biomass weight, days to 50% flowering and fibre weight were found associated with each other. Path coefficient analysis showed that green biomass weight has direct effect on fibre yield per plant. The traits plant height, basal diameter and days to 50% flowering had also indirect effect via green biomass yield on fibre yield per plant. Thus, the result of this investigation suggested that green biomass weight, plant height, basal diameter and days to 50% flowering would be the selection parameters to produce jute varieties with acceptable yield.

TL;DR: There were indications from land equivalent ratio (LER) calculations that the vegetable grower saves more land by intercropping three vegetable species than two (LER 2.0–2.5), and may harvest more Amaranth than the other two vegetable species.
