About Project

All India Coordinated Research Project on Weed Management was started in April 2015 by ICAR-DWR at Dr.PDKV, Akola, Maharashtra. It is the main centres for weed research at State level. Earlier it was a volunteer centre functioning in the Department of Agronomy, Dr. PDKV, Akola since 2009.

 

 

Agro Climatic Information

Vidarbha region of Maharashtra state is mostly characterized by dryland farming. The climatic conditions of this region can be broadly described as semi-arid. The jurisdiction of Dr. Panjabrao Deshmukh Krishi Vidyapeeth is entire Vidarbha region. The region comprises of eleven districts viz. Buldana, Akola, Washim, Amravati, Yavatmal, Wardha, Nagpur, Bhandara, Gondia, Chandrapur and Gadchiroli.

  1. Assured rainfall kharif (Monsoon-June-September) crop zone (ARK) comprises of Buldana, Akola, Washim, Amravati (excluding Warud and Dhamangaon tahsil) and part of Yavatmal (Pusad and Darwha tahsils) district. Its average rainfall is 693 mm distributed in 46 rainy days. July is the most wet month with 204 mm average monthly rainfall. It is essentially a kharif crop area with predominance of cotton and kharif sorghum. These two crops occupy more than 70% of the area. Among pulses udid, mung and pigeonpea in kharif and chickpea in rabi (Winter-October-January) are grown on considerably large area.

  2. Moderate Rainfall Zone (MR) is spread over Yavatmal (except Pusad and Darwha tahsil); Nagpur (except Bhiwapur and part of Umred tahsil); Wardha and Chandrapur (Warora, Rajura tahsil) districts. Average annual rainfall is 1133 mm distributed in 59 rainy days. Maximum monthly average rainfall (323 mm) is received in 16 rainy days in July. Cotton, sorghum and pigeonpea are major kharif crops in this zone. Rabi sorghum is grown in Warora, Rajura and Ramtek tahsil. Mung, udid and Chickpea are grown all over the zone.

  3. High Rainfall Zone (HR) comprises of Bhandara, Gondia, Chandrapur, (excluding Rajura and Warora tahsil), Gadchiroli and Nagpur (Bhiwapur and part of Umred tahsil) districts. Annual rainfall ranges from 1260 mm on western side of the zone to 1700 mm on a far eastern side. Average total annual rainfall is 1402 mm with 61 rainy days. Rainy season is from June to September. However, few showers (about 50 to 60 mm) are obtained in October, which are favourable for rabi pulses. It is predominantly a paddy growing area in kharif and most of the rabi area is under pulses such as chickpea, mung, udid, lathyrus, lentil, dolichos bean etc. Majority of them are under utera condition in which lathyrus is predominant.

Research Activities / Achievements

Ongoing Research Work

  • To study weed dynamics, crop growth and productivity of different crops and cropping systems with different weed management practices.

  • To study the effect of fertigation and weed management practices on crop growth and yield of different cropping system.

  • To study the non-chemical methods of weed management in an organic cotton-chickpea cropping system.

  • To study the effect of different herbicides on cuscuta in soybean+pigeonpea intercropping system

Research Achievements

  • Application of imazethapyr+ imazomox 70% WG (Ready-mix) @ 70 g a.i./ha as post-emergence (PoE) at 20 days after sowing (DAS) was effective and economical treatment in groundnut.

  • Application of imazethapyr + imazamox 70% WG (Ready-mix) @ 70 g a.i./ha as PoE at 15 DAS was the most effective and remunerative in soybean.

  • For effective weed management application of clodinafop-popargyl 15% + metsulfuron methyl 1% WP (Ready-mix) @ 60 + 4 g a.i./ha as POE at 35 DAS was recommended in wheat.

  • In cotton application of pendimethalin 30% EC 1000 g a.i./ha as pre-emergence (PE) (within 48 Hrs after sowing) followed by directed spray (by using protective shield) of non-selective herbicide paraquat dichloride 24% SL @ 60 g a.i./ha as PoE at 45 DAS is recommended.

  • For effective weed management in sole soybean, application of propaquizafop 2.5% + imazethapyr 3.75% ME (Ready-mix) @ 125 g a.i./ha as post-emergence 21 DAS. 

OR

            Application of diclosulam 84% WDG @ 26 g a.i./ ha as pre-emergence (PE) (within 48 Hrs after sowing) is recommended in sole soybean.

  • In Maize application of atrazine 50% WP @ 500 g a.i./ha as PE followed by application of tembotrione 34.4% SC @ 120 g a.i./ha as post emergence at 20 DAS were the most effective and remunerative.

  • In turmeric application of pendimethalin 1000 g ai/ha or metribuzin 70% WP @ 70 g ai/ha or atrazine 750 g ai/ha as PE at 0-5 DAP followed by straw mulch 10 t / ha (10 DAP) fb one HW (75 DAP) was found effective in controlling weeds with higher yield and monetary returns. (Research Findings)

  • Under fertigation in maize for higher grain yield, effective weed management and net returns it is recommended to apply 125 per cent recommended dose of nitrogen and potassium (150 kg N & 75 kg K2O) in five splits through drip and phosphorous (75 kg P2O5) as basal application.

  • For effective weed management and higher net returns of maize it is recommended to apply atrazine 50% WP @ 750 g a.i./ha as PE followed by application of topramezone 33.6% SC @ 25.2 g a.i./ha as PoE at 25 DAS.

  • Application of diclosulam 84% WDG @ 26 g a.i./ha as PE (within 48 Hrs after sowing) followed by propaquizafop 2.5% + imazethapyr 3.75% ME (Ready-mix) @ 125 g a.i./ha as POE at 20 DAS

OR

Diclosulam 84% WDG @ 26 g a.i./ha as PE (within 48 Hrs after sowing) followed by quizalofop ethyl 7.5% + imazethapyr 15%, 98.43 g a.i./ha as PoE at 25 DAS recorded higher pod yield and net returns of groundnut.
