Advantages of ZT over Normal Transplanting

ZTDSR lowers production costs due to lack of any kind of land preparation; • Timely sowing of rice can be done; • Promising technology under less rainfall situation, if prevails during crop growth period; • ZT crop suffers less transplantation shock; • The crop matures 8-10 days earlier; • It experiences less weed pressure due to herbicide use; • Savings in irrigation water use & seed; Savings in Labour & Time; Savings in Fuel; • Maintains soil health • There is an improv

Weed Management in ZT Rice

Chemicals that are used for Weed Management during Zero Tillage Rice Cultivation are: • Glyphosate 41 SL @ 2.0 kg a.i. ha-1 (Roundup/ Glycel @ 8-10 ml litre-1) or Paraquat 25 WSC @ 1.0 kg a.i. ha-1 (Gramoxone 25 EC) at 5-7 days before sowing if there is a mat of weeds • Pre-emergence application of Pendimethalin 30 EC @ 1.0 kg a.i. ha-1 (Stomp/ Pendiguard 30 EC @ 3.3 litres ha-1 or 6.7 ml herbic

Fertilizer Management in ZT Rice

There are three steps to be followed during fertilizer management in Zero Tillage Rice • BASAL DOSE: N: P2O5: K2O @ 80: 40: 40 kg ha-1 (20.5 kg IFFCO 10: 26: 26 and 1.5 kg urea) to be applied simultaneously with seeds of rice. • TOP DRESSING: 12 kg urea at 15-20 DAS & 6 kg urea at PI for 1.0 bigha area. • Sesbania co-culture: 2 kg bigha-1 to be sown simultaneously with the seeds of rice. Fertilizer Management in Normal Transplanted Plots • BASAL: ¼ N + Full P2O5 + ¾ K2O • TOP

Seed Treatment

The seed should be treated with 2.5 g Carbendazim/ kg seed before sowing. TREATMENTS TO BE FOLLOWED • T1: DSR + Pre-emergence herbicide application immediately after sowing in the evening + Split application of N • T2: DSR + Pre-emergence herbicide application immediately after sowing in the evening + Sesbania co-culture & killing by 2,4-D salt at 25 DAS + Split application of N • T3: Normal transplanted paddy & normal fertilizer application

Time of Sowing and Seed Rate

• It is advisable to start Zero Tillage DSR at 8-10 days before onset of monsoon (1st fortnight of June) to facilitate timely crop establishment before rains start in full-swing. • The seed rate recommended is 15-16 kg acre-1 for bold grain rice varieties & 11-12 kg acre-1 for fine grain rice varieties.
