A field experiment was conducted in Rabi season of 2018-19 and 2019-20 at Research farm of Bihar Agricultural College, Sabour to assess the impact of nutrient and weed management on N, P and K uptake by crop and weed in mustard. This experiment with 3 nutrient levels (N1-soil test-based recommended dose of fertilizer (RDF), N2-100 % RDF, N3-125 % RDF) in main plot; 8 weed management (W1-Weedy, W2-Hand weeding (HW), W3-pendimethalin, W4-pendimethalin followed by (fb) quizalofop, W5-pendimethalin fb clodinafop, W6-oxyflourfen, W7-oxyflourfen fb quizalofop, W8-oxyflourfen fb clodinafop) in sub plots, laid in split plot design. Results indicated that in 2018-19, N, P and K uptake by mustard was found maximum under 125% RDF. Hand weeding exhibited highest N, P and K uptake by crop over weedy. Among herbicides, maximum N, P and K uptake by crop was noted with pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE. In 2019-20, hand weeding at 25 and 50 DAS along with 125% RDF exhibited highest N, P and K uptake by crop. Among herbicides, application of pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE along with 125% RDF exhibited highest N, P and K uptake by the crop. In both the years 2018-19 and 2019-20, hand weeding at 25 and 50 DAS along with 125% RDF exhibited N uptake by weeds, zero value being lower than weedy. In 2018-19, application of pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE along with 125% RDF exhibited the lowest N and K uptake by weeds. Among nutrient levels, application of 125% RDF exhibited the lowest P uptake by weeds, however, among herbicides; application of pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE registered the lowest P uptake by weeds. In 2019-20, application of pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE along with 125% RDF exhibited the lowest N, P and K uptake by weeds. Thus it was concluded that pendimethalin 1.0 kg a.i. ha-1 PE fb quizalofop 60 g a.i. ha-1 PoE along with 125% RDF (100:50:50:25:6.25 kg NPKSZn ha-1) enhanced N, P and K uptake by crop though hand weeding at 25 and 50 DAS along with 125% RDF (100:50:50:25:6.25 kg NPKSZn ha-1) exhibited significant improvement in nutrient uptake by crop.

A field experiment was conducted in rabi season 2018-2019 and 2019-2020 at Research farm of Bihar Agricultural College, Sabour to study the effect of nutrient levels and weed management on zinc and sulphur uptake by crop and weeds in mustard. This experiment consisted of three nutrient levels (N1-soil test-based recommended dose of fertilizer (RDF), N2-100 % RDF, N3-125 % RDF) in main plot; eight weed management practices (W1-Weedy, W2- Hand weeding (HW), W3-pendimethalin, W4-pendimethalin followed by (fb) quizalofop, W5-pendimethalin fb clodinafop, W6-oxyflourfen, W7-oxyflourfen fb quizalofop, W8-oxyflourfen fb clodinafop) in sub plots, was laid out in split plot design. Results indicated that in both the years 2018-19 and 2019-20, hand weeding at 25 and 50 DAS along with 125% RDF exhibited minimum Zn uptake by weeds. Among herbicides, application of pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE along with 125% RDF exhibited lowest Zn uptake by weeds. In both the years 2018-19 and 2019-20, hand weeding at 25 and 50 DAS along with 125% RDF recorded minimum S uptake by weeds. Lowest S uptake by weeds was noted under application of pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE along with 125% RDF. In 2018-2019, Zn uptake by mustard was maximum under 125% RDF being at par with soil test-based RDF and was superior over 100% RDF. Hand weeding at 25 and 50 DAS exhibited highest Zn uptake by mustard. Maximum Zn uptake by mustard was noted with pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE. In 2019-2020, hand weeding at 25 and 50 DAS along with 125% RDF exhibited highest Zn uptake by mustard. Among herbicides, application of pendimethalin 30 EC @ 1.0 kg a.i. ha-1 PE fb clodinafop 15 WP @ 60 g a.i. ha-1 PoE along with 125% RDF registered highest Zn uptake by mustard. In 2018-2019, hand weeding at 25 and 50 DAS exhibited highest S uptake by mustard. Maximum S uptake by mustard was recorded with pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE. In 2019-2020, although hand weeding at 25 and 50 DAS along with 125% RDF exhibited highest S uptake by mustard, however, pendimethalin 30 EC 1.0 kg a.i. ha-1 PE fb quizalofop 5 EC 60 g a.i. ha-1 PoE along with 125% RDF registered highest S uptake by mustard.

Kour et al (2014) in chickpea + mustard intercropping system and Singh et al (2015) in mustardalso reported similar beneficial effect of integrated approach for better weed management and higher mustard yieldand also obtained the results for highest seed and straw yield in indian mustard under weed free check . Seed yield of mustard linearly decreased as the weeds dry matter increased.…”

Abstract:Field investigation was carried out during rabi season of 2014-15 at Udaipur to evaluate the effect of different weed management practices on yield and nutrient uptake of mustard. The maximum seed yield was registered with two hand weeding (1955.25 kg ha -1 ) except weed free check and was at par with fluazifop-p-butyl 0.055 kg ha -1 10 DAS + hoeing 40 DAS and fenoxaprop-p-ethyl 0.075 kg ha -1 10 DAS + hoeing 40 DAS. The highest amount of total N, P and K (112.61, 25.31 and 76.90 kg ha -1 , respectively) was removed by mustard in weed free treatment followed by two hand weeding while the lowest N, P and K with the values of 70.11, 16.05 and 51.86 kg ha -1 , respectively was removed by weedy check followed by isoproturon 0.75 kg ha ha -1 . Among the weed management practices, the total uptake of N, P and K by weeds was found significantly less in all the weed management practices as compared to weedy check(5.87, 0.86 and 5.51 kg ha -1 , respectively). The least nutrient depletion by weeds was registered with the hand weeding twice (0.52, 0.08 and 0.49 kg ha -1 , respectively) followed by fluazifop-p-butyl 0.055 kg ha -1 10 DAS + hoeing 40 DAS and fenoxaprop-p-ethyl 0.075 kg ha -1 10 DAS + hoeing 40 DAS. Use of post emergence herbicides of 'fop' group such as fluazifop-p-butyl, quizalofop-p-ethyl, fenoxaprop-p -ethyl (which are mostly used in soybean and groundnut crop) in indian mustard found most effective in controlling grassy weeds in early stage whereas at latterly, one hoeing 40 DAS was found effective in controlling grassy as well as broad leaved weeds under irrigated conditions.
