ABSTRACT
A field experiment was conducted during kharif 2016 at College of Agriculture, Hassan, University of Agricultural Sciences, Bengaluru to evaluate different pre and post emergent herbicides on growth and yield of potato (Solanum tuberosum L.) the soil of experimental site is red sandy loam in texture, neutral in reaction and medium in available nitrogen, phosphorus and potassium. The experiment was laid out in a RCBD with seven treatments replicated thrice. Application of Fenoxaprop–p-ethyl 54 gm a.i. ha-1 as early post emergent at 20 DAP recorded significantly higher growth parameters viz; plant height (64.4 cm), number of sField experiments were conducted during kharif and rabi for two consecutive years (2010-11 and 2011-12) to evaluate the direct and residual effect of various organic manures and crop residues alone and along with jeevamrut on productivity and economics of soybean – wheat cropping system. Three organic manures ( FYM, vermicompost and compost) alone and along with jeevamrut, three crop residues (cotton, wheat and soybean) @ 5 ton ha-1along with jeevamrut were applied/incorporated in soil one month before sowing to both soybean and wheat crop. Only nitrogen level was balanced through manures and no phosphorus and potash were applied, jeevamrut was applied @ 500 l ha -1at 30 and 45 DAS. The pooled results of two years revealed that significantly higher soybean grain equivalent yield (33.48 q ha -1), production efficiency of system (19.41 kg day -1ha -1) and maximum B:C ratio (2.21) were recorded with 100 % RDN through vermicompost + jeevamrut (T6) followed by 100 % RDN through vermicompost (T3).

hoots plant-1 (8.03), number of leaves plant-1 (21.0), leaf area (724 cm2), leaf area index (0.60), total dry matter plant-1 (7.30 g) over weedy check (48.67 cm, 4.33, 10.33, 400 cm2, 0.33 and 4.84 g, respectively). Application of Fenoxaprop–p-ethyl 54 gm a.i. ha-1 as early post emergent at 20 DAP recorded significantly higher number of tubers plant-1 (4.30), tuber weight plant-1 (250.50 g) and tuber yield (19.77 t ha-1) which was on par with Quizalofop–p-ethyl (4.07, 247.37 g and 18.93 t ha-1, respectively) except weed free check.
