| Conclusion |
: |
- On the basis of two years study on “Integrated Nutrient Management for Sustainable Wheat (Triticum aestivum L.) Production in Western U.P.” the highest growth characters were recorded with 100% RDF through inorganic source of nutrient which were statistically similar to the treatment of 75% NPK + 1 ton ha-1 vermicompost + Azosprillium and significantly higher than the rest of the treatments and control. Among the different combination of organic manures with inorganic source of nutrients, 75% NPK + 1 ton ha-1 vermicompost + Azosprillium recorded significantly higher yield attributes and yield along with higher gross return and net return and Soil organic carbon (%). Although application of 100% NPK yielded more among all the nutrient management options but it was found at par with 75% NPK + 1 ton ha-1 vermicompost + Azosprillium in grain yield, gross return and net return. In view the buildup of Soil organic carbon and improvement in nutrient availability, application of 75% NPK + 1 ton ha-1 vermicompost+ Azosprillium was found best among all nutrient management options. Keeping in view the sustainability of soil health 75% NPK + 1 ton ha-1 vermicompost + Azosprillium proved better. Thus 75% NPK + 1 ton ha-1 vermicompost + Azosprillium may be suggested for good performance of wheat crop and sustainability of soil health and crop yields in future.

Effect of pre and post emergence application of different doses of imazethapyr along with other herbicides on weed dynamics, yield of black gram and succeeding mustard crop |
| Conclusion |
: |
- All weed control practices proved effective in controlling the weeds in black gram and gave significantly higher grain yield over weedy. PRE application of imazethapyr + pendimethalin (RM) at 900 g a.i./ha-1 most effective control of all major weeds resulting maximum grain yield among herbicide treatments which was at par with two hand weeding employed at 20& 40 DAS. And PRE use of pendimethalin at 1000 g ha-1 provided control of weeds with slight crop suppression which although mitigated within 10-15 days after spray resulting reduction in grain yield & yield attributing character. This treatment influenced the uptake of nutrient by black gram and reduced density and dry matter of weeds. No residual carry over effect of any herbicide applied in black gram was absorbed on succeeding mustard crop as is evident from crop growth parameters and seed yield of mustard. As per the finding of imazethapyr + pendimethalin (RM) at 900 g ha-1 or pendimethalin alone should be adopted for the control of weeds in black gram without any phytotoxity on black gram and succeeding mustard crop. The net return and B:C ratio were also higher with PRE application of imazethapyr + pendimethalin (RM) at 900 g ha-1 and two hand weeding 20& 40 DAS.

Evaluation of tillage-cum-crop establishment methods under irrigation scheduling on soil properties, water productivity and yield of wheat (Triticum aestivum L.) |
| Conclusion |
: |
- Furrow irrigated raised bed tillage responded better under CRI + 50 mm CPE because this planting system require lower amount of water and can be irrigated frequently in a very short duration. Moreover, this technology has immense scope of mechanization and less dependence on manpower requirement thus, FIRB, a new technology should be disseminated in wheat growing areas for increasing production and productivity of wheat under intensive farming system category.
- The zero tillage crop establishment technology has also immense scope of mechanization and less dependence on manpower requirement. Besides, it requires shortest duration for field preparation, helps in matching the optimum climatic conditions and can be performed with residual moisture condition. These opportunities helps in early germination and better growth as well as higher physiological performance viz. net photosynthesis rate, chlorophyll content, net transpiration rate and lower stomatal conductance resulting in higher shoot growth obtained from better root growth due to favourable soil properties. Such soil and soil moisture characteristics resulted in better growth parameters and resulted in higher yield attributes and yield with minimum input. Water scheduling with CRI + 100 mm CPE is most favourable scheduling for sustainable production, productivity and economic return in wheat crop cultivation.
