“…1). By the consistency with our results, variations among herbicides in nutrient uptake by weeds (Prashanth et al 2016) and crop (Dash et al 2016) were reported. Pyrazosulfuron caused 75.7, 73.9, and 73.8% reductions in N, P, and K uptakes by weeds, respectively (Talla and Jena 2014).…”

Due to the ability of weeds to deplete nutrients from the soil, crop plants become subjected to a complex of abiotic and biotic stresses. Thus, the interactive effects between one of the most important micronutrients, i.e., zinc (Zn) and some herbicides on weeds, rice yield and nutrient uptake were investigated. The experiment was carried out in a randomized complete block design in factorial arrangement using three replicates. Ten combinations of two Zn levels (without Zn, Zn−, and with Zn, Zn+) as well as four herbicides (halosulfuron-methyl, bentazon, azimsulfuron, pyrazosoulfuron-ethyl), and unweeded treatment were investigated. Findings clarified that application of halosulfuron-methyl herbicide whether with Zn− or Zn+ were the effective combinations for decreasing weed biomass. Halosulfuron-methyl and pyrazosoulfuron-ethyl had similar impact either with Zn− or with Zn+ resulted in minimum values of K uptake by weeds. The increases in grain yield ha −1 due to the application of halosulfuron-methyl, pyrazosoulfuron, azimsulfuron, and bentazon reached 13.4, 15.9, 21.3, and 24.8%, respectively, under Zn+ greater than Zn−. Halosulfuron-methyl x Zn+ was the promising interaction treatment for increasing P, K, and Zn uptakes by rice. Correlation coefficient showed that fertile panicle number, fertile grain number, rice N and K uptakes, weed biomass, and weed P uptake were the most closely associated traits with grain yield. Our study proved that there is a positive correlation between Zn and the applied herbicides in rice. Zn application alleviated the herbicidal pressure (abiotic stress) and decreased weed harmful impacts (biotic stress) on rice plants. Thus, it should be focused on the complementary effect between Zn and applied herbicides in breeding programs for generating new rice genotypes which are efficient in Zn utilization and tolerant to herbicides.

“…Though the rice yield and gross return were the highest under hand weeding at 15, 30 and 45 DAS, the data on net income and return per rupee invested showed that it was less remunerative than pendimethalin at 1.0 kg ha -1 at 2 DAS + bispyribac sodium at 25 g ha -1 at 20 DAS and pendimethalin at 1.0 kg ha -1 + one manual weeding at 30 DAS which implied that it was uneconomic and unnecessary to give three hand weeding during the entire crop growth.The net income was found negative under weedy check due to greater competition between rice and weed which led to poor growth of the crop, lower grain and straw yield. This is in conformity with the study conducted by Prashanth et al, (2016) who reported that the lowest net returns and B: C ratio was obtained in unweeded check in transplanted rice.…”

“…This again emphasized the importance of weed management in profitable rice production. This is in conformity with the study conducted by Prashanth et al (2016) who reported that the lowest net returns and B:C ratio was obtained in unweeded check in transplanted rice. Kashid et al (2015) reported that significantly the highest net return and return per rupee invested was obtained with the pre-emergence application of herbicide integrating with one hand weeding or one post emergence herbicide.…”

A field experiment was conducted at KVK, South Tripura during the Kharif season of 2013 and 2014 to study the integrated weed management in direct-seeded upland rice. The predominant weed flora in the experimental field were Amaranthus viridis, Oldenlendia corymbosa, Spilanthes acmella, Ludwigia parviflora, Cleome rutidosperma, Malvestrum coromondalianeum among the broad-leaf weeds, Digitaria sanguinalis among grasses and Cyperus iria among sedges. The results revealed that though the hand weeding thrice at 15, 30 and 45 DAS recorded lowest weed dry weight and the highest grain yield, it was not economically viable. The pre-emergence application of pendimethalin at 1.0 kg/ha at 2 DAS + bispyribac-sodium at 25 g/ha at 20 DAS recorded the highest net returns and return per rupee invested and appeared to be the most promising and remunerative weed management practices for direct-seeded rice under Tripura condition followed by pendimethalin at 1.0 kg/ha at 2 DAS + one hand weeding at 30 DAS.
