Abstract: |
Different types of experiment on rice crop were carried out during 20581059 and 20591060. The trials were conducted at RARS Parwanipur and simultaneously on farm experiments were conducted in the farmers field with the participation of farmers at different outreach research sits of command districts. Varietal testing, effect of legume on rice yield in rice wheat system: different fertility managed trials on yield. In case of Aromatic rice cultivars were tested including one fine non aromatic rice Pusa 834. Highest mean grain was observed !Jy CNTLR 85033 ((4428 kg!ha). While varietal trials of normal rice for irrigated conditions. BR 4684 ranked first at all locations follawed by released popular cultivars Sabitri (4940 kg/ha and 4600 kg!ha). Highest mean grain yield was observed where Zinc Sulphate was applied as basal dose with recommended dose of chemical fertilizer follawed by recommended dose with butachlor (4130 kg/ha and 3950 kg/ha) respectively. Significant difference in rice yield was obtained where lentil was planted in comparison to mustard n rice based pattern. Front line on farm trials indicated the possibility of high yield with improved package of practices. The result of different types of experiments indicated the potential possibility of higher rice. It can be concluded by observing the results of different types of researcher managed trial conducted at on station, on farm and farmers managed trial. While using popular short duration varieties BG /442, the mean rice yield obtained was 4699 kg!ha, while the mean yield of farmers managed trial was 4075 kg!ha Side by side incase of normal duration rice, Sabitri produced 5500 kg/ha in research managed trial. FMT produced 4370 kg!ha was produced by farmers managed trial. Yield was increased significantly when ZnSo4 was applied with basal dose of chemical ftrtilizer. No significant yield difference was observed between basal application and foliar application of zinc sulphate and chilated zinc respectively. Yield gap between the trials conducted at on station and on farm ORR sites indicated the need of correcting soil health status of e."Cperimenta/ plots of research station by introducing legume. Low yield may also be the effect of environmental condition which differed between research station and ORR sites, while yield difference between outreach research managed trial and farmers managed trials at ORR sites indicated the socioeconomic conditions of farming community which prevented them to use recommended dose of inputs at higher cost. Side by side unawareness about application of technology at proper time and proper method in rice cultivation. |
