Spurred anoda (Anoda cristata) interference in wide row and ultra narrow row cotton

William T. Molin; Debbie Boykin; Josie A. Hugie; et al. Weed Science 2006. doi:10.1614/ws-05-072r1.1

Other claims from this paper (15)

Association Spurred anoda density and dry weight per plot were linearly related each year.
Observation At 8 m −2, spurred anoda dry weight was 507 g m −2 in 2000.
Observation At 8 m −2, spurred anoda dry weight was 322 g m −2 in 2001.
Observation At 8 m −2, spurred anoda dry weight was 777 g m −2 in 2002.
Intervention effect Spurred anoda did not interfere with seed cotton yield in 2001.
Intervention effect Yield losses exceeded 55% at spurred anoda density of 8 m −2 in both row spacings relative to controls.
Association The effect of spurred anoda density on cotton boll numbers was nearly identical in 2000 and 2002 across cultivar and row spacing.
Intervention effect Boll weights decreased with spurred anoda interference.
Intervention effect Spurred anoda interference decreased cotton branch dry weight in wide rows.
Intervention effect Spurred anoda interference did not decrease cotton branch dry weight in ultra narrow rows.
Mechanism In ultra narrow rows, yield decrease under spurred anoda interference was attributed to plant mortality.
Association Cotton plant density decreased by one plant for each additional spurred anoda in ultra narrow rows.
Intervention effect Yield per surviving cotton plant remained constant under spurred anoda interference in ultra narrow rows.
Intervention effect Neither row spacing conferred significant advantage in response to spurred anoda interference.
Recommendation Decreased boll weight and lack of compensatory boll number increase in ultra narrow rows may limit producer appeal.

Effects of 1,2,4--trichlorobenzene and naphthalene on grain yield and quality of rice

Zegang Wang; Ding-zhen WAN; Ya-Chun Yang; et al. Zhongguo shuidao kexue 2006

Other claims from this paper (15)

Intervention effect TCB significantly reduced survival percentage of rice seedlings.
Intervention effect NAP had little effect on survival percentage of rice seedlings.
Intervention effect TCB and NAP delayed the heading date of rice.
Mechanism Decreases in number of panicles per pot and seed setting rate were two main reasons for the rice yield reduction.
Intervention effect Both organic pollutants affected rice grain quality.
Intervention effect Effects of the organic pollutants on chalkiness were the greatest among the grain quality traits.
Intervention effect The organic pollutants next affected milled rice rate, head rice rate and protein content, in that order.
Intervention effect The organic pollutants affected amylose content next, after the other grain quality traits.
Intervention effect Both pollutants had little effect on brown rice rate of the two tested varieties.
Observation NAP content in grains was about ten times TCB content.
Observation Shanyou 63 accumulated more organic pollutants than Wuyunjing 7.
Intervention effect Organic and inorganic fertilizer application reduced the harm of TCB and NAP to rice.
Intervention effect Organic and inorganic fertilizer application increased rice grain yield.
Recommendation Good-quality irrigation water supply is necessary for higher survival of rice seedlings after transplanting.
Recommendation Controlling TCB and NAP content and reasonable cultivation are very important for high grain yield and food safety.
