RECOMMENDATIONS FOR PACKAGE OF PRACTICES (2018-19)

AAU, Anand

  • Weed flora shifted towards monocot weeds in wheat fields due to continuous use of 2, 4-D or MSM. Herbicide mixtures were found more effective to manage complex weed flora in wheat crop.
  • Application of oxyfluorfen 240 g/ha PE fb HW at 60 DAP along with paddy straw mulch 5 t/ha was found more effective to manage weeds and produce higher garlic bulb yield.
  • In maize based cropping system application of atrazine + pendimethalin (500 + 250 g/ha) PE (tank mix) fb 2, 4-D 1000 g/ha PoE found effective weed management practices. No any adverse effect of herbicides on succeeding wheat crop was observed.
  • The highest seed cotton equivalent yield was achieved under zero tillage with residue treatment. Application of pendimethalin 900 g/ha PE fb IC+HW at 30 and 60 DAS recorded significantly higher seed cotton equivalent yield as compared to quizalofop ethyl 50 g/ha PoE fb IC+HW at 30 DAS in cotton-green gram cropping system under conservation agriculture.
  • Fennel equivalent yield and gross return was recorded higher under vermicompost 8.0 t/ha, while net return and benefit cost ration was recorded under farm yard manure treatment. Paddy straw mulch 10 t/ha fb HW at 30, 60 DAS recorded higher fennel equivalent yield, gross return, net return and benefit cost ratio.

  • Application of penoxsulam+ cyhalofop 6%OD 900 ml/acre at 15-20 days after transplanting as spray in 120 liter water to control complex weed flora in transplanted rice. There should be no standing water one day before and one day after herbicide application.
  • Application of penoxsulam 2.5%OD 360 ml/acre at 15-20 days after transplanting as spray in 120 liter water to control complex weed flora in transplanted rice. There should be no standing water one day before and one day after herbicide application..
  • To control resistant population of minor, A. ludoviciana and broadleaf weeds in wheat, a ready mix combination of clodinafop+metribuzin 200 ml per acre along with surfactant (500 ml) should be sprayed at 35 DAS using 120 litres of water.

CSKHPKV, Palmpur

  • For higher productivity of maize-wheat system, zero tillage with or without residues followed by IWM (herbicide + mechanical weeding + intercropping) in both crops was found to be the effective treatment.
  • Under organically managed maize – garlic cropping system, raised stale seed bed + mulch or hoeing; intercropping and intensive cropping may be an effective mean of suppressing weeds and increasing garlic bulb equivalent yield.
  • Pre-emergence application of metribuzin 0.7 kg/ha or pendimethalin1.0 kg/ha fb mulch (2-5 DAP) fb hoeing (75 DAP) could be an effective integrated weed management strategy in turmeric.
  • Mixture of indaziflam 125 g/ha + glufosinate ammonium 1000 g/ha during the month of January and then again in the month of July gave selective control of weeds in tea. However, indaziflam 62.5 g/ha + glufosinate ammonium 1500 g/ha gave higher net returns.
  • Pre-emergence application of the imazethapyr + pendimethalin at 1200 g/ha may be the better option for managing mixed weed flora and obtaining higher fruit yield of okra.
