Conservation agriculture is a potential solution for increasing yield in wheat crop in the rice wheat cropping system. A study was carried out to assess the impact of the conservation practices in rice-wheat cropping system. The experiment was conducted at the PAU, Ludhiana during 2010-2013. The design of an experiment was split-plot with 12 treatments and 3 replications. The main plot treatments of rice (zero till direct seeded rice, ZT-DSR; conventional till direct seeded rice, CT-DSR; zero till direct transplanted rice, ZT-DTR and puddled transplanted rice, PTR) and sub-plot treatments of wheat (conventional till wheat without rice straw, CTW-R; ZT wheat without rice straw, ZTW-R, and ZT wheat with rice straw retained as surface mulch using Happy Seeder, ZTW+R). The treatment ZTW+R recorded significantly higher grain yield (5.26 t ha-1) than other treatments. The yield attributes viz., 1000 grain weight, spike length, grain weight per spike and grains per spike were significantly higher in ZTW+R than that of ZT/CT with no straw. Significantly higher macronutrients (N, P and K) and micronutrients (Zn, Fe, Mn and Cu) uptake were recorded under ZTW+R compared with ZT/CT without rice straw. The study recommended that the conservation agriculture practices will gives better soil environment for crop growth and development which may be responsible for enhancement of grain yield and nutrient uptakes.
