“…It also might be due to Sesbania being an aquatic plant helped to suppress most of the weeds and provided the needed nutrients to Rice as well as succeeding wheat crop. This finding is in close agreement with the result of Goswami et al (2018).…”

Present study was undertaken to assess the scope of Sesbania aculeata as brown manure on grain yield, partial factor productivity of nutrients as well as to cut down the nutritional requirement of direct seeded rice and transplanted rice-wheat system cropping system. Results revealed that puddled transplanted treatment having 100% NPK with Sesbania aculeata recorded highest rice grain yield (4.3 t ha‒1) which was statistically at par to dry direct seeded rice treatment having 100%, 75% and 50% NPK with Sesbania aculeata. The yield of wheat taken after puddled transplanted rice was recorded lower than the wheat grown after direct-seeded rice. System productivity, PFP, AUE, net returns and B: C ratio of DSR-wheat was higher (7.5 t ha‒1, 25 kg grain/kg nutrient applied, 3.3%, USD 870 ha‒1, 1.2) compared to puddle transplanted rice-wheat (7.4 t ha‒1, 24.5 kg grain/kg nutrient applied, 0.6 %, USD 786 ha‒1, 0.9, respectively). The highest B: C ratio (2.4) was recorded in treatment having 50% NPK of recommended dose, which was statistically at par with the treatment having 75% NPK of recommended dose. Interaction effect of nutrient application coupled with crop establishment method revealed that the highest B:C ratio (1.7) was registered also in DSR-wheat system having 75% and 50% NPK of recommended dose.

“…The results clearly show significant reduction in weed density due to application of pendimethalin as pre-emergence herbicide. Goswami et al, (2017) also recorded lower weed density in pendimethalin applied treatments and stated that application of pendimethalin as pre-emergence can significantly reduce the weed density and dry weight in DDSR field. Application of weed management options followed by pre-emergence herbicide significantly reduces the weed density and dry weight.…”

Weed is one of the major constraints for success of dry direct seeded rice (DDSR) technology. The productivity, weed density and weed dry weight of DDSR is influenced by weed management practices. A field experiment was done to evaluate tillage methods and weed management practices on weed dynamics and yield of DDSR using split plot design; each treatment replicated thrice. The treatment consisted of two tillage methods in the main plots, and eight weed management practices in the sub-plots. Gorakhnath-509 was the variety of rice used. Weed flora observed in the experiment comprised of 25 weed species, belonging to 12 families. Among them 12 were broadleaf weed, belonging to 10 families; 8 were grasses, belonging to Poaceae family, and the rest 5 were sedges, belonging to Cyperaceae family. Tillage methods did not influence weed density and weed dry weight in DDSR, but weed management practices reduced weed density and dry weight at all dates of observation compared to weedy check. All the weed management practices significantly improved the grain yield of DDSR in both tillage methods. Treatments with higher grain yield of DDSR were, use of pendimethalin followed by hand weeding (3,742 kg ha-1); pendimethalin followed by bispyribac-Na (3,552 kg ha-1), and pendimethalin followed by tank mixture application of bispyribac-Na and ethoxysulfuron(3,638 kg ha-1), but were statistically similar (p>0.05). Results thus supports the fact that application of popular pre-emergence herbicide- pendimethalin followed by manual weeding, or post-emergence herbicide, such as Bispyribac-Na, or tank mixture of post emergence herbicides bispyribac-Na and Ethoxysulfuron could be the most effective weed management practices in both tillage method of rice cultivation.

“…Pre-emergence application of herbicides prevented the emergence of weeds and also controlled the weed growth during earlier stages of rice growth and weeds that emerged at later stages of crop growth were not controlled effectively (Begum et al, 2008). Goswami et al (2017) It was observed that pendimethalin@1 kg a.i ha -1 fb bispyribacsodium @ 25 g a.i ha recorded significantly lower total weed density and dry weight than other weed management in direct-seeded rice. Higher total weed density (46.19m -2 ) was observed in pre-emergence application of herbicide pendimethalin@1.0 kg .ha -1 at 3days after receipt of sowing rain followed by star weeder at 30 days after receipt of sowing rain.…”

A field experiment was carried out at Agricultural Research Station, Paramakudi, Tamil Nadu during 2017- 18 to study the interaction between weed ecology, competition and management strategies in semi-dry Direct Seeded Rice. The fieldexperiment was laid out in split- plot with irrigation in main plot and weed management in sub plot. The results revealed that least weed density was recorded after irrigation when water level droped to 10cm below soil surface. Among weed management practices hand weeding twice at 20 and 40 days after sowing (DAS)has recorded the lowest weed density with highestweed control efficiency. Among the interactions, lowest weed density and highest weed control efficiency was recorded when water level droped to 10 cm below soil surface with combination hand weeding twice at 20 and 40 DAS.
