Other claims from this paper (4)

Method / resource Plots one to three rows wide and 10 to 15 hills long were most efficient.
Recommendation Two-row plots 10 to 15 hills long were considered optimal for general use.
Recommendation A basic unit larger than five plants may be advantageous.
Recommendation The precision gain did not justify using simple lattice over randomized blocks.

D. J. WATSON; GILLIAN N. THORNE; S. A. W. FRENCH Annals of Botany 1958. doi:10.1093/oxfordjournals.aob.a083616

Other claims from this paper (19)

Association Proctor and Herta yielded 10—15 per cent more grain than Plumage-Archer without nitrogen fertilizer.
Intervention effect Nitrogen increased the varietal grain yield difference to about 30 per cent.
Intervention effect Higher nitrogen caused Plumage-Archer lodging without increasing its yield.
Observation Proctor and Herta remained standing under higher nitrogen.
Observation The three varieties had similar leaf-area index, net assimilation rate and total dry weight before ear emergence.
Association After ear emergence Herta had a smaller leaf-area index than Proctor and Plumage-Archer.
Observation Shaded-ear pot experiment found nearly equal dry matter contribution per leaf area across varieties.
Mechanism The authors attributed higher yield to photosynthesis by the ears.
Association In pots, Proctor and Herta yielded only about 6 per cent more than Plumage-Archer.
Association Field ear sizes were greater for Proctor and Herta than Plumage-Archer.
Association Ear dry weight at emergence was greater in the higher yielding varieties.
Observation Herta ears may have higher photosynthetic efficiency.
Association Plumage-Archer absorbed more potassium.
Association Herta absorbed less phosphorus than the other varieties.
Observation About a quarter of final nitrogen was absorbed after ear emergence.
Observation A third of phosphorus was absorbed after ear emergence.
Observation Potassium content was nearly maximal at ear emergence and later decreased.
Observation Ear photosynthesis contributed 26 per cent of grain dry matter, including 10 per cent from awns.
Observation Flag-leaf lamina, sheath and peduncle supplied 59 per cent of grain dry matter, and lower shoots supplied 15 per cent.

Yoshio SOGA; Michio NOZAKI Japanese Journal of Crop Science 1957. doi:10.1626/jcs.26.105

Other claims from this paper (14)

Association Sugars and starch in leaf sheaths and culms were associated with grain production.
Intervention effect Inhibition of photosynthesis decreased starch content faster than sugars.
Intervention effect Inhibiting photosynthesis 16–7 days before heading decreased accumulated carbohydrates.
Intervention effect Early ripening led to lighter thousand-kernel weight.
Observation Early ripening decreased spikelets per ear.
Observation Carbohydrate reaccumulation in culms was maximal among plots with reduced accumulation power.
Intervention effect Shading at 6–15 days after heading caused increased transport of accumulated carbohydrates to the ear.
Observation Shading at 6–15 days after heading increased incompletely developed grains.
Intervention effect Photosynthesis inhibition at 16–25 days after heading delayed grain development.
Observation Photosynthesis inhibition at 16–25 days after heading increased poorly developed grains.
Observation Photosynthesis inhibition at 16–25 days after heading lowered thousand-kernel weight.
Intervention effect Shading 26–35 days after heading did not influence kernel development.
Association Culm carbohydrate accumulation was positively related to photosynthetic power and accumulation to the ear.
Observation Authors estimated carbohydrate accumulation suitable for seed production at about 28–29%.

Intervention effect The 3-paddock rotational system maintained milk production as well as or better than the 6-paddock, strip and zero grazing systems.
