Seed is the most important input to harvest a good crop. The potential yield of crop depends on the quality of the seed used for cultivation of crop. Use of quality seeds alone can enhance the crop productivity by 15-25%. One of the main reasons for low productivity of crops is unavailability of reliable quality seeds in the local markets. To enhance productivity, seed should be of high quality...

The effect of applying plant growth regulators on seed yield and quality of guinea grass (Panicum maximum) cv. Tanzania was studied in one crop on a sandy clay in Mexico. The treatments consisted of 3 growth regulators [ethephon, salicylic acid and a steroidal phytohormone (cidef-4)], 2 stages of application (before seed head emergence and at the beginning of anthesis) and 4 application concent...

background and objectives: the most important determining factor in sugar beet root yield is seed quality. seeds with germination percentage are lower; the germination is slow and non-uniform, will produce plants that initial growth is slow. according to various studies indicate that harvest time is an important factor influencing the quality of sugar beet seed. in the early harvest of sugar be...

Intense selection for specific seed qualities in winter oilseed rape breeding has had an inadvertent negative influence on seed germination performance. In a panel of 215 diverse winter oilseed rape varieties spanning over 50 years of breeding progress in winter-type rapeseed, we found that low seed erucic acid content and reduced seed glucosinolate content were significantly related with prolo...

Ten yearling steers weighing 270-360 kg died acutely after eating early seed pod stage Lupinus argenteus (silvery lupine) containing high levels of piperidine alkaloids, including ammodendrine and N-methylammodendrine. Reduced availability of Quality feed from range moderately depleted of Quality grasses appeared a major factor in causing the cattle to graze lupine. Proximate analysis of whole ...
