Title

Emergence Force of Forage Seedlings¹

E. H. Jensen; James R. Frelich; R. O. Gifford Agronomy Journal 1972. doi:10.2134/agronj1972.00021962006400050026x

Other claims from this paper (12)

Observation Emergence force differed among four forage legumes.
Association Emergence force was positively correlated with seed weight.
Observation Alfalfa had higher mean weekly emergence force than other tested species.
Observation Narrowleaf birdsfoot trefoil had lower mean weekly emergence force than other tested species.
Observation Legume emergence force rose rapidly 24 to 48 hours after transplanting.
Observation Legume emergence force gradually declined thereafter.
Intervention effect Tall wheatgrass emergence force did not significantly decrease until −5.0 bars osmotic potential.
Intervention effect Lower osmotic potential increased time to maximum force in alfalfa.
Intervention effect Lower osmotic potential did not increase time to maximum force in tall wheatgrass.
Observation Tall wheatgrass needed 5 to 6 days to reach maximum force.
Observation Legumes needed 1 to 2 days to reach maximum force.
Intervention effect Sodium adsorption ratios did not affect alfalfa emergence force.

Title

Effect of water management on forage production and on carbohydrate and nitrogen constituents of alfalfa (Medicago sativa L.).

A. A. Schneiter UA Campus Repository (The University of Arizona) 1973

Other claims from this paper (19)

Observation dry matter production decreased in summer under high and medium irrigation.
Observation plant height at harvest decreased in summer under high and medium irrigation.
Observation efficiency of water use decreased in summer under high and medium irrigation.
Observation total water utilization per growth period decreased in summer under high and medium irrigation.
Observation Daily water use increased in summer under high and medium irrigation.
Intervention effect After irrigation resumed, dry matter production under low water was not significantly different from medium and high water.
Intervention effect After irrigation resumed, harvest plant height under low water was not significantly different from medium and high water.
Observation Alfalfa stand density declined across three production years.
Intervention effect Water management did not significantly influence stand decline or root distribution.
Observation Root morphology varied among genotypes, largely attributed to genetic expression.
Intervention effect Water stress significantly increased root proline content.
Intervention effect Water stress significantly decreased root arginine content.
Intervention effect Water stress significantly increased root sucrose content.
Intervention effect Water stress did not affect root fructose and glucose levels.
Observation Water-insoluble N was lower at midsummer than at the start and end of the season.
Observation Water-soluble protein was lower at midsummer than at the start and end of the season.
Intervention effect Total available carbohydrates and water-soluble protein decreased after harvest.
Observation Water-insoluble N, soluble N, protein amino acid composition and free sugar did not change during regrowth.
Observation TAC decreased in midsummer under medium and high irrigation each year.
