Important package of practices and their impact

•Use of gypsum is necessary for compact filling of groundnut (250 kg/ha to 500 kg/ha), source of Calcium & Sulphur.

•Phosphorus should be supplies through SSP not through DAP. •Selection of variety according to soil type and sowing time.

•Seed should be shelled 7-30 days before sowing.

•Seed treatment with 3 gm Thiram or Mencozeb 2 gm/ kg seed for the control of collar rot.

•Application of Phorate (10%) or Quinalphos (5%) @ 25 kg /ha before groundnut sowing to control the attack of white grub up to 35-40 days.

•In the standing crop use of 4 lit quinalphos 25 EC or emidacloropid 200 S.L. @ 300 ml/ ha with irrigation control the white grub attack on later stage.

•Looking to the geographical variability in the state and based on edaphic factors there are three distinct categories of situations in which groundnut is cultivated in the Rajasthan State •The lighter soil area of Jaipur, Sikar, Dausa, Sawaimadhopur and other districts where virginia types are cultivated.

•The heavy soils of Bhilwara and Chittorgarh districts where spanish groundnut is preferred.

TG 37A, TBG 39 and Pratap Mungfali 1The irrigated area of north and north-west of Rajasthan where virginia types are in vogue.
