Direct seeding in rice is a popular practice that saves cost of crop establishment. However, weeds pose a serious challenge to crop growth and yield in direct seeded rice. To ensure uniform crop stand and manage weed growth, a novel method of use of Pre- seeded mulch has been developed. Pre-seeded mulch developed from organic waste materials have a residence time of 60 days in soil. Paddy seeds fixed in these sheets, when laid in the field got 95% seed germination. Weed control efficiency in terms of weed count and weed dry matter, of the technology is significantly higher than the hand weeding. Rice yield and yield attributes were also high for the pre- seeded mulch technology compared to wet seeding and transplanting.

The AICRP on long term fertilizer experiment was established at RARS Pattambi in 1997 and the experiment is being conducted continuously in the same field. The objective of the experiment was to study the effect of long term application of fertilizers and manures on growth and yield of the plant and monitoring of soil quality. The experiment consists of 12 treatments. The LTFE experiment with 20 years cropping history revealed the superiority of integrated nutrient management with 100 per cent NPK along with FYM over the sole use of fertilizers. However in situ growing of dhaincha (Sesbania aculeata) also offer a good solution for integration of manures and fertilizers. Integrated nutrient management and in situ green manuring with daincha recorded higher grain and straw yield and the growth parameters corroborated the trends in yield.Keywords

To study the impacts of elevation of CO2 on rice-wheat system, a pot culture experiment and a field experiment were undertaken. The pot culture experiment was conducted in open top chambers (OTCs) with surface soils collected from a typic haplustept (IARI, New Delhi). Rice and wheat were grown as test crops at ambient (approx. 370 mol mol-1) and elevated (600±50 mol mol-1) levels of atmospheric CO2. Total biomass yield was increased by 32.26 and 33.83 per cent as a result of elevation of CO2 concentration in the micro climate of rice and wheat, respectively. Various plant parts differed with respect to their relative gain in yield and the relative gains in biomass of different plant parts on exposure to elevated CO2 were in the order of: Rice: Grain (48.11) > Leaves (43.97) > ischolar_mains (34.95) > stem (18.80) and Wheat: Root (70.54) > Leaves (42.50) > grain (35.39) > stem (21.00). At all stages of crop growth, exposure to higher CO2 in atmosphere increased the preferential partitioning of carbon to ischolar_mains both in rice and wheat.Keywords
