Effect of Depth of Tillage on Yield of Upland Paddy and on Associated Weeds

H. K. Pande; V. M. Bhan Experimental Agriculture 1966. doi:10.1017/s0014479700026752

Other claims from this paper (6)

Association Bulk density was negatively correlated with dry matter of crop roots and grain yield.
Intervention effect Tillage to 28 cm significantly reduced weed population and dry matter compared with tillage at 7 and 14 cm.
Association There were significant relations between weed dry matter and grain yield.
Intervention effect Crop roots under tractor tillage were significantly greater than with 7 cm tillage.
Intervention effect Grain yield was maximum under 28 cm tillage, followed by 21, 14 and 7 cm tillage in that order.
Association Higher grain yields were associated with more fertile tillers per metre of row and higher yields per tiller.

Coaracy M. Franco; Walter Lazzarini; Armando Conagin; et al. 1960

Other claims from this paper (6)

Intervention effect Nitrogen application increased coffee yield in each year from 1954 to 1958, with yield increases of 8.4% to 63.1%
Intervention effect An application of 800 g KCl per tree gave only a 9% yield increase relative to 200 g per tree
Intervention effect Microelement spray cured zinc deficiency symptoms in coffee
Intervention effect Phosphorus application gave no reaction in coffee
Intervention effect Green manure gave no reaction in coffee
Recommendation Mineral fertilizers alone can substantially increase coffee plantation yield
