本来文涉及Rajouri区tehsil Nowshera的杂草对小麦作物产量的影响。在研究过程中，作者在2009- 2010年期间在tehsil Nowhera的Jaba村选择了两块各01公顷的地块（P1和P2）。图P1标记为无杂草图（WF），图P2标记为杂草图（WP）。两块地均翻耕，并通过添加等量的NPK肥料（尿素150 kg、DAP 100 kg和钾肥40 kg/hq）来准备苗床。在2009年11月的第一次播种期间，在两个地块中播种相同品种的小麦种子。氮肥尿素分次施用（播前50 kg、40 DAS 50 kg、开花前50 kg）。在小区P1（WF）中，在播种后35天喷洒两种类型的除草剂，即2，4-D和异丙隆@0.75kg/hq。对阔叶杂草和狭叶杂草的防效分别为：在二月间，人们用手拔草，用镰刀铲除杂草。2010年3月。在小区P2（WP）中，没有喷洒除草剂，也没有进行除草，因此从该小区报道了28种杂草。成熟后，从两个地块收获作物（在2010年5月的第一个收获季节）并分别脱粒。将收集在不同袋中的谷物称重。从小区P1（WF）和小区P2（WP）分别收集了28.4公担和21.2公担的小麦籽粒。在P2区（WP），杂草与小麦竞争，使小麦减产25.35%。（Journal of American Science 2010;6（10）：405-407）。(ISSN：1545- 1003）。
The present communication pertains to the effects of weeds on the yield of wheat crop in tehsil Nowshera of district Rajouri. During the course of study the authors have selected two plots of 01 hectare each (P1 and P2) in village Jaba of tehsil Nowhera during the year 2009-10. The plot P1 was marked as Weed Free plot (WF) and plot P2 as Weedy Plot (WP). Both the plots were ploughed and the seed beds were prepared by adding equal amount of NPK fertilizer (Urea150 kg, DAP 100 kg and Potash 40 kg/hq). Same variety of wheat seeds were sown in both the plots during first weak of Nov. 2009. Nitrogen fertilizer urea was given in split doses (50kg before sowing, 50 kg 40 DAS and 50 kg before flowering). In plot P1 (WF) 35 days after sowing two types of herbicides were sprayed i.e. 2, 4-D and isoproturon @ 0.75 kg/hq. for broad leaved and narrow leaved weeds respt. and deweeding (hand pulling and eradicating weeds with the help of digger and sickle) was done during the month of Feb.-Mar. 2010. In plot P2 (WP) no herbicide was sprayed and no deweeding was done as a result 28 weeds were reported from this plot. After ripening the crop was harvested (during first weak of May 2010) from both the plots and threshed separately. The grains collected in different bags were weighed. A total of 28.4 quintal of wheat grains were collected from plot P1 (WF) and 21.2 quintal from plot P2 (WP). The weeds competes with wheat crop in plot P2 (WP) and hence reduced the yield by 25.35%.
