摘要

本研究于2014、2015、2016年连续3个农作季，在比卡纳尔拉贾斯坦邦农业大学农业研究站研究农场进行了14种防治杂草的田间试验，分别为:甲氧苄啶1.0 kg/ha (PPI)、甲氧苄啶1.0 kg/ha (PE)、丙氧苄啶+丙氧苄啶800g/ha、丙氧苄啶+丙氧苄啶900g、丙氧苄啶+丙氧苄啶1000g、丙氧苄啶50g、丙氧苄啶70g/ha、丙氧苄啶+丙氧苄啶60g/ha、丙氧苄啶+丙氧苄啶70g/ha、丙氧苄啶+丙氧苄啶60g/ha、丙氧苄啶+丙氧苄啶70g/ha。氟氧芬40g/ha、对乙基苯丙沙普50g/ha、丙喹沙普62g/ha，无杂草和杂草检查，随机区组设计，3个重复。无杂草对花生杂草的控制效果最好，阔叶杂草和禾草杂草的杂草数和干物质均最低。在不同除草剂中，喷施800g吡甲醚+ pendamethalin对阔叶杂草和禾草杂草的数量和干物质均有有效控制，花生的产量属性和产量显著高于其他所有除草剂处理，即干物质积累(75.5 g)、荚果数(31.2)、荚果数(2979 kg/ha)、收获量(7711 kg/ha)和生物产量(10690 kg/ha)。不同除草剂中，喷施咪唑吡虫啉800g的净收益最高，为84132/手，B:C比为2.22。

Herbicidal weed management in groundnut (Arachis hypogaea)

A field experiment was conducted at Research Farm of Agriculture Research Station, S K Rajasthan Agricultural University, Bikaner during 3 consecutive kharif season of 2014, 2015 and 2016with fourteen weeds control treatments of pendimethalin 1.0 kg/ha (PPI), pendimethalin 1.0 kg/ha (PE), imazethapyr + pendimethalin 800g/ha, imazethapyr + pendamethalin 900g, imazethapyr + pendamethalin 1000g, imazethapyr 50g, imazethapyr 70g/ha,imazethapyr + imazemox 60g/ha, imazethapyr + imazemox 70g/ha, oxyfluorfen 40g/ha, fenoxaprop p-ethyl 50g/ha, propaquizafop 62g/ha, weed free and weedy check in randomized block design with three replications. Weed free was found most effective to control weeds in groundnut and recorded lowest weed count and weed dry matter of both broad leaved and grassy weeds. Among the different herbicides, application of imazethapyr + pendamethalin 800g recorded efficiently controlled weed count and weed dry matter of both broad leaved and grassy weeds as well as significantly highest yield attribute and yield in groundnut over all the other herbicidal treatments viz. dry matter accumulation (75.2g), number of pods/plant (31.2), pod (2979 kg/ha), haulm (7711 kg/ha) and biological yield (10690 kg/ha). Among the different herbicides, application of imazethapyr + pendamethalin 800g recorded higher net returns of84132/haand B:C ratio of 2.22.
