Effect of forchlorfenuron on yield and economics of transplanted rice

Influence of Vigore and tab-sil (SiO2) on Productivity and Profitability of Transplanted Rice (Oryza sativa L.) under Southern Dry Zone of Karnataka

“…Increase in panicle weight and number were mainly due to higher growth attributes owing to improvement in availability of plant nutrients through improved root system and higher uptake of nutrients from soil by improving photosynthesis efficiency of plant. These results are in conformity with Singh et al, (2017). Application of 100 % recommended dose of fertilizer (100:50:50 Kg NPK ha -1 )with Tab-sil100 % Silicate Tabs (SiO2) 2.5 kg/ha at 25 DAT and 2.5 kg/ha at 50 DAT resulted significantly higher grainand straw yield (7092and 7696kgha -1 , respectively) followed by application of RDF with Tab-sil100%+ Silicate Tabs (SiO 2 ) 5 kg/ha at 50 DAT (6500 and 7694 kgha -1 , respectively).…”

“…It also increases the supply of oxygen to the rice plant roots. This alleviates the excessive amount of ferrous iron and also toxicity of H 2 S (Singh et al, 2017). Hence, there is necessity to evaluate the effectiveness of Vigore and Tab-sil products along with recommended dose of fertilizer for maximization of rice yield.…”

“…However, increase in rice yield with silicon tablet application along with 100% RDF might be due to increased availability of silicon in soil solution. The lower yield in control plot without silicon might be due to leading to fixation loss of native silicon in submerged conditions which is unavoidable to meet out the Silicon requirement by the crop (Singh et al, 2017).…”

Integrative Weed Management Tactics for Rice (Oryza sativa L.) under Direct-Seeding in Kymore Plateau and Satpura Hills

“…The NMR was found highest (Rs 35184 ha -1 ) in hand weeding two times at 20 DAS and 40 DAS, respectively. Similar results were mentioned previously by [25] and [26] in transplanted rice. This was specifically due to attainment of highest grain and straw productivity under hand weeding treatment.…”

“…ha -1 at 20 DAS + conoweeder at 40 DAS treatment because of proportionate enhancement in economic return because of lower cost involving in the management of weeds under this treatment than others. Similar results were mentioned previously in transplanted rice by [25] and [26]. This treatment was followed by hand weeding 2 times at 20 and 40 DAS treatment (1.79) (Table 7).…”
