“rotational application of chlorimuron + metsulfuron-methyl 4 g/ha PoE during previous year and bispyribac-sodium 25 g/ha PoE during next year after conventional tillage in transplanted rice under CT(TPR)-CT(W)-fallow system and ZT+S in rice under ZT+S(R)-ZT(W)-ZT(GG) system has resulted lower weed density and biomass along with higher weed control efficiency, higher grain and straw yields and economic returns than other combinations.”

3 of 5 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
