| dc.description.abstract | The present study entitled “Effect of herbicide and Integrated nutrient management on growth, and yield of French bean (Phaseolus Vulgaris L.)” was undertaken at Agricultural Research Farm, Institute of Agricultural Sciences,BHU. The experiment was laid out in a split plot design with three replications. Five weed management treatments, viz., Quizalofop-ethyl@ 50 g a.i. ha-1 at 20 DAS (Post-emergence), Pendimethilin@ 1.0 kg ha-1 (per-emergence), Pendimethilin@ 1.0 kg ha-1 (per-emergence) fb quizalofop-ethyl@ 50 g a.i. ha-1 at 20 DAS (Post- emergence), Weedy check, 2HW (20+40 DAS) were allotted to main plot. Five different fertility levels viz., RD (120 kg N, 60 kg P, 40 kg K and 20 kg S), RD+200 kg ha-1 Wellgro soil (dust), RD+300 kg ha-1 Wellgro soil (dust), 75% RD+200 kg ha-1 Wellgro soil (dust) and 75% RD+300 kg ha-1 Wellgro soil (dust) were allocated to sub plots. Thus, all total twenty five treatment combinations were replicated thrice to into seventy five plots. Plot size was kept 5 x 3 m2 and the net plot size was 4 x 2.4 m2 with the block and plot border 1 metre each. The test crop variety HUR-137 was grown having same set of treatments and the whole setup was repeated during the second year to confirm the results. The sources of inorganic fertilizers were Urea, DAP, MOP and SSP and Wellgro soil. As per treatment, full dose of nitrogen, phosphorus, potassium, SSP and Wellgro soil were applied as basal (just before sowing of the crop). Application of pendimethalin @1.0 kg ha-1 fb quizalofop-p-ethyl@ 50 g ha-1 resulted into lowest weed density and weed dry weight with NPK removal, next to the hand weeding, and proved significantly superior to rest of the treatments during both the years of study. The highest weed control efficiency and lowest weed index were also associated with this treatment. Similarly, application of pendimethalin @1.0 kg ha-1 fb quizalofop-p-ethyl@ 50 g ha-1 was found most effective in increasing growth, yield attributes, yield and quality parameter of French bean and proved significantly superior to other weed management treatments during both the years of study. Application of pendimethilin@ 1.0 kg ha-1 fb quizalofop- ethyl@ 50 g a.i.ha-1 at 20 DAS recorded significantly highest gross return, net return and B: C ratio over other weed management treatments during both the year of studies. The significantly higher N, P, K and S content in grain and straw and its uptake were recorded under the application of pendimethilin@ 1.0 kg ha-1 fb quizalofop- ethyl@ 50 g a.i.ha-1 at 20 DAS next to the hand weeding was found significantly superior to rest of the treatments in the respect during both the years. Application of RD+300 kg ha-1 Wellgro soil (dust) recorded significantly lowest density and weed dry weight with NPK removal of Chenopodium album, Melilotus indica, Melilotus alba and Cyperus rotendus as compared to rest of the treatments except RD+200 kg ha-1 Wellgro soil (dust) where both were at par with each other. Among fertility levels, the highest weed control efficiency and lowest weed index were found under the application of RD+200 kg ha-1 Wellgro soil (dust) during both the year of investigation. The application of RD+300 kg ha-1 Wellgro soil (dust) recorded significantly higher plant height (cm), branches plant-1, trifoliate leaflets plant-1, dry matter accumulation (g plant -1), root dry weight (g plant-1), root nodules (number plant-1) and root nodule dry weight (mg plant -1) as compared to rest of the treatments at all the growth stages of crops during both the years of study. Similarly, application of RD+200 kg ha-1 Wellgro soil (dust) proved significantly superior to rest of the fertility levels with respect to yield attributes. The significantly higher grain yield and harvest index were recorded by RD+200 kg ha-1 Wellgro soil (dust), whereas, straw yield was highest under the treatment of RD+300 kg ha-1 Wellgro soil (dust), but both the treatments were at par with each other. Application of RD+200 kg ha-1 Wellgro soil (dust) recorded significantly higher gross return, net return and B: C ratio over rest of the fertility treatments except RD+300 kg ha-1 Wellgro soil (dust) during both the years of study. However, treatment 75% RD+300 kg ha-1 Wellgro soils (dust) was at par with 75% RD+200 kg ha-1 Wellgro soil (dust) in respect to gross return, net return and B: C ratio during 2009 and 2010. | en_US |
