Highly productive rice (Oryza sativa L.) and wheat (Triticum aestivum L.) cropping systems are crucial for millions of rural and urbans in the Indo-Gangetic Plains (IGP) of south Asia. This intensive RWCS resulted in declining under groundwater table and degrading soil health. A number of resource conservation technologies are being propagated in the region to uplift declining water productivity and soil health. Among different propagated resource conservation technologies-double zero tillage (ZT-wheat) in both crops found to be adopted in the region at a large scale which lessens cost of cultivation with no-field preparation and no-pre-sowing irrigation factor. Further, as wheat sown in loose and anchored rice straw thus, emit burning of rice residues and finally, reduces air pollution and improves "blank gold" status (Soil organic carbon). Zero tillage supposed to improve the declining soil physical properties; crop and water productivity thought visible effects appeared after 4-5 years of adoption. The treatment included two tillage levels viz., conventional and zero tillage and three rice tillage viz., puddle, conventionally and zero tilled with two establishment methods viz., direct seeded rice (DSR) and mechanically transplanted rice (MTR). Objective of the present study was to delineate the effect of double zero tillage from 2012-2014 on the soil physical environment and findings suggests that double tillage was not able to significantly effect of the physical properties of the soil as adaptation of CA based component technologies evolved over the time. Thus, best benefits of double zero tillage might be significant after 3-5 years of continuous adoption of the double zero tillage which further needs to be tested under different agro-climatic conditions under texturally divergent soils.Keywords

On-farm trials (OFTs) at eighteen different farmer field locations varying in soil fertility were conducted (2006-08) to assess the relative performance of different nitrogen sources viz., neem coated urea (NCU) and ordinary urea (OU). The treatments thus compared consisted of 96 and 120 kg N ha-1 through NCU and OU, thus, constituting T1=80% NCU, T2=80% OU, T3=100% NCU and T4=100% OU. The grain yield for wheat and rice in T3/T4 was significant (p<0.05) (6.9% and 13.8%, respectively) higher than T1/T2, however, the grain yield among equivalently applied N treatments was statistically at par. The results revealed no significant differences in agronomic efficiency of N (AEN) applied through different sources at equal applied level. However, there was significantly higher AEN for T1/T2 than T3/T4 in both wheat and rice. The total energy productivity for wheat in T3/T4 was 6.87 per cent higher, with a decrease in energy productivity by 0.11 MJ ha-1 than T1/T2. However, in rice the total energy productivity was 14.9 per cent higher in T3/T4 with 0.16 MJ ha-1 over T1/T2. Thus, it can be concluded that the two N sources are equally effective for rice-wheat cropping in sub-tropical soils.Keywords
