Abstract:

The dominant weed flora under weedy check recorded at 60 DAS were Cyperu.\rotunelus. Phaloris minor. Rumex denticulata. Chenopodium album, Melilotus spp. and Anagallis arvensis. Zero tillage was dominated by sedge, whereas reduced and convcntionLlI by broad-leaved weeds, specially Rumex dentit'ulata which suppressed all other weeds at late stages of crop growth. Isoproturon atlkg ha'i (30 DAS) fb 2, 4-D 0.5 kg ha- ' (40 DAS) was more effective to minimize weed density and their dry weight under all the tillage treatments than glyphosat~ at 0.5 I fb isoproturon at 1.0 kg ha", sulfosulfuron at 25 g ha" and isoproturon at 1.0 kg ha'i. The minimum weed control efficacy was observed in alone application of sulfosulfuron and isoproturon. On an average, isoproturon fb 2, 4-D increased the grain yield by 42.3, 38.0 and 39.1% over weedy check in zero, reduced and conventional tillage, respectively.

Abstract:

Clodinafop and fenoxaprop alone could successfully control Phlliaris mit/or but were found ineffective against Rumex maritimus. Me/i/otus indi<;a and Corot/opus dydillltls. Tank mixture of clodinafop (60 g ha") and fenoxaprop (100 g ha") with carfentrazone (20 g ha") controlled both grassy and broadleaf weeds resulting in 88-90% weed control efficiency and signi ticantly increased seed yield of wheat over sole application of c1odinafop and fenoxaprop, tank mix of metribuzin and isoproturon with carfentrazone and metsul furon. Metribuzin sole as well as in tank mix with carfentrazone and l11etsulfuron was not found suitable due to its toxicity to wheat. The succceding crops of moongbean, cowpeas and forage sorghul11 did not show any residual activity of herbicides applied in wheat.

Abstract:

Field experiments were conducted at the experimental farm of the Department of Agronomy and Agromet.. PAU. Ludhiana. during 2003-04 and 2004-05. The experimental field was sandy-loam in texture with 72.7% sand. 11.7% silt and 15.6% clay and was under rice-wheat sequence from last many years. Wheat sown with zero till technique after the spray of paraquat recorded significantly less dry matter of Phalaris minor as compared to conventional till sown crop. Also the dry matter of broadleaf weeds was found to be significantly higher in zero till sown crop without paraquat application than the other tillage treatments. Mesosulfuron+iodosulfuron 12 or 15 g ha" and sulfosulfuron 25 g ha" provided effective control of P minor and broadleaf weeds. whereas clodinafop 60 g ha" and fenoxaprop-p-ethyl 100 g ha" controlled only P minor. Significantly higher grain yield was recorded in zero till sown crop after spraying paraquat than zero till without paraquat spray as well as conventional tillage treatments and the former treatment gave 15.8% higher yield than the latter ones. On an average of two years. highest grain yield (4266 kg ha,l) was recorded in meso+iodo 15 g ha" and it was followed by slllfoslIlfllron. fenoxaprop-p-ethyl fb 2. 4-0 and clodinafop fb 2. 4-0. respectively.

Abstract:

Flufenacet at 200-500 g ha", applied before or after first irrigation resulted in 40 to 69% and 44 to 72% control of grassy and broadleaf weeds, respectively. Metribuzin at 200 to 400 g ha" provided control of both grassy (75-90%) and broad leaf weeds (79-93(%). Metribuzin beyond 300 g-I was toxic to wheat. Sulfosulfuron resulted in higher grain yield due to very effective control of grassy (87-90%) and suppression of broadleaf weeds (35%), however, it was statistically at par with clodinafop at 60 g ha· l, fenoxaprop at 120 g ha· 1 and metribuzin at 200 and 300 g ha· '.

Abstract:

Clodinafop at 50 and 60 g ha- ' and fenoxaprop at 100 and 120 g ha- ' were very effective (85-90%) against grassy weeds but totally ineffective against broadleaf weeds in wheat. Triasulfuron at 20 to 25 g ha- ' was not at all effective against grassy weeds but highly effective (80-93%) against broadleaf weeds. Sulfosulfuron at 20 to 25 g ha- ' provided 7984% control of grassy weeds and 21-47% control of broadleaf weeds. Tank mixture of triasulfuron at 25 g ha- ' with c1odinafop at 50 g ha- ', fenoxaprop at 100 g ha- ' or sulfosulfuron at 20 g ha- ' proved very effective (76-87%) against both grasses and non-grasses in wheat.

Abstract:

Sulfosulfuron at 25 g ha- ' and mesosulfuron+iodosulfuron at 12 g ha- I were applied 4. 7, 10, 15, 18 and 21 days after first irrigation (DAFI) to the wheat crop. First irrigation was given 25 days after sowing the wheat crop. The bioefficacy of these herbicides for controlling Phalaris minor was not affected due to stage of application and was similar to clodinafop. Herbicides applied 4 or 7 DAFI caused reduction in grain yield of wheat. However, application of these herbicides at other stages produced similar grain yields. Herbicides treated plots produced higher grain yield (67.4-86.7%) than unweeded crop.

Abstract:

Effect of rice establishment methods and weed management practices on weeds and grain yield of rice was studied. The maximum reduction of weed species was obtained with application of herbicides as pre-emergence supplemented by two hand weedings at 30 and 60 DAS/DAT under all the establishment systems of rice. The maximum weed dry matter reduction was achieved under herbicides fb two hand weedings in transplanted rice followed by herbicide as pre-emergence supplemented with two hand weedings in wet seeded rice and application of herbicide as pre-emergence supplemented with two hand weedings in zero till rice. The highest yield (4623 kg ha") was achieved by the application of herbicide supplemented with two hand weedings in transplanted rice which was significantly higher than the other treatments. Among the direct seeded rice the highest yield (4222 kg ha") was recorded under wet seeding employed with two hand weedings and on par with application of herbicide followed by one hand weeding under transplanting.

Abstract:

Progressive increase in doses of both pendimethalin (from 1.0 to 2.0 kg ha- ' ) and anilofos (from 0.4 to 0.8 kg ha- ' ) resulted in decreased density and dry weight of all the weeds at 60 days stage. However, both the herbicides were more effective when 2, 4-0 at 0.5 kg ha- ' or bentazon at 0.72 kg ha- ' were applied as follow up application. With follow up treatment pendimethalin at 1.0 kg ha" with 2, 4-0 at 0.5 kg ha- ' recorded highest grain yield and weed control efficiency. Among alone applications oxyfluorfen at 0.25 kg ha- ' was most effective as it was able to control both broad-leaved weeds and grasses, however, it was not as effective as herbicide combinations in obtaining grain yield.

Abstract:

A field experiment was conducted during kharif seasons of 200 I and 2002 at Rajasthan College of Agriculture, Udaipur to study the effect of planting pattern and weed control methods on weeds and productivity of maize and soybean. Intercropping of maize with soybean, irrespective of their row ratio, effectively reduced the weed density and dry weight of weeds at 50 DAS compared to their pure cropping. The grain yield of maize in intercropping with soybean was statistically on par with its yield in pure stand; however, productivity of soybean crop was significantly reduced in intercropping system compared with its sole cropping. Maize-equivalent yield in maize+soybean (2 : 2) planting pattern made remarkable improvement (55.55 q ha- ' ) compared to remaining planting patterns. Alachlor and pendimethalin integrated with one hoeing at 25 DAS were found superior in reducing population as well as dry matter of weed at 50 DAS. Alachlor+hoeing at 25 DAS gave the highest maize equivalent yield (50.88 q ha-I) which was on par with that obtained with pendimethalin+hoeing (49.09 q ha-I ).

Pre-plant incorporation of fluchloralin at 1000 g ha" was not effective on Cuscuta. Post-emergence application of imazethapyr (50 and 100 g ha") and glyphosate (50 g ha") killed the extended vines of Cuscuta and checked its growth upto 25-30 days only. Maximum seed yield of lentil (4175 and 3407 kg ha- ' ), chickpea (3615 and 2949 kg ha") and linseed (1994 kg ha- ') was recorded in Cuscuta free plots. Pendimethalin at 1000 g ha- ' in all three crops, squadron at 3000 g ha" in chickpea and glyphosate at 50 g ha- I in linseed significantly increased the seed yield. Squadron was phyto-toxic to lentil and linseed. Imazethapyr and glyphosate (except at 50 g ha" in rinseed) were phyto-toxic to the crops.

Abstract:

Unchecked weed growth throughout growing period caused 52% reduction in tuber yield of potato. Weed-free condition beyond 45 days had no significant effect on tuber yield of potato. The critical period of crop-weed competition was between 15-45 days after planting (DAP) during which weed-free maintenance would be required for achieving the maximum tuber yield of potato under vertisol. The highest tuber yield of potato (17.90 t ha") was recorded with N120P60K60 under low weed pressure, while the lowest (4.07 t ha") with NoPoKo under high weed pressure, which indicated that maximum fertilizer use efficiency (49 kg tuber yield kg" nutrient applied) could be obtained in the absence of weed competition. However, per cent increase in tuber yield of potato with increasing levels of fertilizer was more pronounced under high weed pressure compared to low weed pressure.

Abstract:

The present investigation was undertaken to study the effects of temperature on adsorption-desorption of isoproturon on a clay soil and fit the data obtained to Freundlich adsorption-desorption isotherm model. The adsorption curves revealed that adsorption of isoproturon conformed to a L-type adsorption isotherm at the higher temperature (20"C), while a S-type at lower temperature (I OUC). The adsorption of isoproturon decreased with the increase in temperature, indicating the exothermic nature of adsorption :·eactions. The phenomenon of hysteresis appeared to be more pronounced at lower temperature than at higher temperature.
