1300. Cheema, S.S., D.S. Kler and D.S. Grewal. 1985. Improve wheat yields through bi-directional sowing.. Indian Farming, 35:7-9.
Experiments for 8 seasons showed that bi-directional sowing suppresses weeds, minimises the incidence of powdery mildew and brown rust. Primary yield contributing character was the higher number of effective tillers per unit area. Uniformly spaced plants without overcrowding within the rows, get more solar radiation. Relatively less penetration of light to ground surface resulted in lower soil temperature in bi-directional sowing.

5508. Rai, R.N.. 1980. Weed control in rainfed wheat of Doon Valley.. Indian J. Agron., 25(2):197-200.
The 2,4-D treatment did not give favorable response. Hand-weeding, giving highest wheat yield, provided 331 kg Chenopodium album leaves, a nutritive source of leafy vegetables and proved remunerative.

6276. Singh, H. and J.P. Agarwal. 1983. Studies on nitrogen fertilization and weed management in wheat.. Indian J. Agron., 28(1):23-29.
About 40-45 kg N/ha could be saved by pre-emergence application of tribunil over the conventional method of weeding.

6293. Singh, H.P. and J.P. Agerwal. 1982. Studies on nitrogen fertilization and weed management in wheat.. Indian J. Agron., 27(1):71-77.
Nitrogen fertilization did not affect composition, density and dry matter accumulation in weeds. The concentration of N in weeds tended to increase with nitrogen application. Tribunil for weed control. Liberal doses of fertilizers and frequent irrigation have been adopted to realize maximum yields in Mexican dwarf wheats, and have stimulated the rank growth of weeds. The weed flora of wheat has greatly changed in the recent past and some new obnoxious non-legume weeds like Phalaris minor and Avena fatua have come into prominence. Similarity to wheat plant in early stages.

6301. Singh, R.A., O.P. Singh and M. Singh. 1976. Effect of soil compaction and nitrogen placement on weed populations.. Plant and Soil, 44:87-96.
Field experiements showed that soil compaction did not affect wheat yield significantly under rainfed conditions. Weed population was significantly reduced due to soil compaction. Compaction decreased total moisture use and increased water use efficiency. Weed population was not affected due to nitrogen placement. Under rainfed conditions, deep placement of nitrogen was important for increasing the efficiency of fertilizer as well as water utilization by wheat crop.

6600. Soni, P. and R.S. Ambasht. 1977. Effect of wheat crop-weed competition on the mineral structure of wheat crop.. Agro-ecosystems, 3:325-336.
It was found that the reduction in the concentration of nitrogen and phosphorous in the wheat plant started at the vegetative stage itself due to interference from weeds in the weedy stand and the maximal reduction was at the flowering stage (perhaps due to the maximal density of weeds at that stage). From the above investigation it is concluded that weeds growing along with crop plants significantly affect the mineral status of the crop as well as uptake, return and retention by wheat plants.
