This research focused on the germination dynamics of forage kochia accessions as it relates to harvest date planting date age of seed and environmental conditions The effect of planting date age of seed and environmental conditions on forage kochia germination was elucidated by planting recently harvested (2010) and year-old cold-stored edible seeds provide the basic source of carbohydrates and protein for people in many parts of the African continent The area planted to cassava in sub-Saharan Africa is estimated to be 8 9 million hectare producing 72 million tons annually (Sengooba 1994) Insect pests in

Effect of date of harvest on seed quality and viability of

Field experiments were made in both 1974 rainy seasons in Ibadan Nigeria to evaluate the effect of harvest time on seed quality and viability of soya beans (Glycine max (L ) Merr ) The first harvest was made when about 85% of the pods had ripened and subsequent harvests were made at 7-day intervals

Effect of different harvest date and refrigerated storage on the firmness of two blackberry cultivars: "Obsidian" and "Triple Crown" at 2012 and 2013 harvest Comparing harvest years in both cultivars the fruits from the 2012 harvest were firmer than those harvested in 2013 and the effect of storage showed variation among the two

Over the recent past a reduction of the time required for grapes to achieve sugar ripeness possibly a result of climate change has been observed in many countries raising the issue of a potential disconnect between flavor ripeness and sugar accumulation An experiment using Vitis vinifera L cv Riesling was conducted to test the relationship between sugar content of fruit and harvest date

Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production However little information exists concerning how to reap the best quality seeds of Leymus chinensis which is the dominant and most promising grass species in the Songnen Grassland of Northern China The objective of this study was to investigate and evaluate possible quality

Optimum harvest maturity for Leymus chinensis seed

May 03 2016production The optimum harvest time on seed germination is also very important For the Leymus chinensis seed the effect of harvest time has yet to be determined To reap good quality seed timely harvest is important to seed viability and vigour Early harvesting may result in low yield and poor seed quality whereas late harvesting may also

Hubner Junior and Toledo (2016) evaluating the viability of cowpea seeds harvested at different seasons after physiological maturity in non-desiccated areas and with pre-harvest desiccation through the application of the herbicide paraquat observed that harvest delay reduces the viability and germination of cowpea seeds regardless of pre

Mar 18 2020Some plant seeds including cool season vegetables like lettuce and broccoli germinate best in temperatures between 55 and 70 F (13 to 21 C ) while warm season plants such as squash and marigolds germinate best when temperatures are between 70 and 85 F (21 to 13 C ) So whether it's extreme heat or cold temperature does affect plants and their growth

Sep 01 2013Further seed weight per spike also varied significantly between the two varieties Seeds from NERICA-1 were significantly heavier than those from Ex-China Table 3 shows that the two varieties varied considerably on 1000- grain weight Under the different row spacings a significant difference was also observed on 1000 grain weight

The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE a PGR) affect PM HM seed viability and seed vigor of red clover at different stages of maturity 2) evaluate the effect of irrigation TE and their interaction on seed yield its components and the quality of red clover seeds at harvest 3
