Title

Effect of Nitrogen Top Dressing on Ripening of Japonica and Indica Rice

Kazuo NAGATO; Norimasa YAMADA; Fateg Muhammad CHAUDHRY Japanese Journal of Crop Science 1971. doi:10.1626/jcs.40.170

Other claims from this paper (19)

Observation At heading, indicas had less plant carbohydrate than japonicas.
Observation Indicas had more spikelets per panicle than japonicas.
Observation Indicas had a shorter ripening period than japonicas.
Intervention effect Nitrogen top dressing lowered carbohydrate content at heading in indicas.
Intervention effect Nitrogen top dressing increased spikelets per panicle in indicas, especially on secondary branches.
Intervention effect Top dressing caused more inferior indica kernels to stop growth and become sterile, abortive and opaque.
Intervention effect Top dressing decreased normal kernel grain weight in indicas.
Intervention effect In japonicas, top dressing scarcely decreased carbohydrate content.
Intervention effect In japonicas, top dressing produced only a small increase in flowers per panicle.
Intervention effect Top dressing slightly worsened ripening in japonicas.
Intervention effect Top dressing slightly increased japonica grain weight.
Intervention effect Grain yield per panicle rose in two japonica varieties.
Intervention effect Dular grain yield remained unchanged.
Intervention effect Te-Tep grain yield decreased more strongly.
Intervention effect Karalath grain yield decreased to 84%.
Intervention effect Heavy manuring considerably increased panicles per plant in japonicas.
Intervention effect Heavy manuring increased panicles per plant only slightly in indicas.
Intervention effect Heavy manuring increased yields in japonicas.
Recommendation The authors recommend nitrogen fertilizer where panicle number rises while flowers per panicle stay almost constant.
