SUMMARYField experiments consisting of three mulch treatments (no mulch, straw mulch and dust mulch) and six transpiration suppressants (no suppressant, kaolin, phenyl mercuric acetate, atrazine, mobileaf or alachlor and 2-chloro ethyl trimethyl ammonium chloride) were conducted under dryland conditions during the summer rainy seasons (July–November) of 1976, 1977 and 1978. Compared with no mulch, straw mulch increased yield in all 3 years, water use efficiency in 1977 and 1978, and uptake of N and of P in 1977 and 1978. Dust mulch had only a marginal advantage. Amongst transpiration suppressants, only kaolin and atrazine had a marked effect. Both these chemicals increased grain yield, water use efficiency and uptake of N and P, compared with no suppressant.

SUMMARYThe results of field experiments conducted in the spring seasons (February/March to June) of 1980 and 1981 indicate that grain yields of sorghum increased with increase in frequency of irrigation. Crops sprayed with atrazine or CCC yielded more than the unsprayed control; maximum yields were obtained by the application of atrazine at 200 g ha−1. Water use efficiency decreased with increase in irrigation but increased as a result of spraying crops with either chemical. Irrigation water can be saved by the spraying of atrazine or CCC onto spring-sown sorghum.

Background: Wheat is an important food crop of world. This crop has the wider adaptability due to its genetic makeup. The sowing environment and varieties interaction plays important role to enhance its productivity and optimum utilization of the resources. As this crop has wider adaptability so we planned our experiment to study the grain yield, heat use and water use efficiency of diverse wheat varieties which have been recommended in different wheat growing zones, sown at different environment in North-western India, to increase the varietal spectrum.Methods: The field experiment was conducted in 2017-18 and 2018-19 at the research farm of the Punjab Agricultural University, Ludhiana, India. The experiment was conducted with four sowing dates (November 5, November 25, December 15 and January 5) in main plot and six wheat varieties (HS 562, HD 2967, HD 3086, HI 1544, MACS 6222 and WR 544) in sub-plot of split plot design with three replications. Result: The wheat crop sown on November 5 recorded the highest emergence count, plant height, heat use efficiency, normalized difference vegetative index, yield attributes, grain yield and water use efficiency than later sowing dates. Among the wheat varieties, HS 562 recommended for northern hill zone recorded heat use efficiency, helio-thermal use efficiency, at Leaf value, effective tillers, grains per earhead, grain yield and water use efficiency similar to HD 3086 recommended for North-western zone. The varieties recommended for other zones like HI 1544, MACS 6222 and WR 544 could not perform similar to the HD 3086.

SUMMARYNo-tillage and raised beds are widely used for different crops in developed countries. A field experiment was conducted on an irrigated maize-wheat system to study the effect of field layout, tillage and straw mulch on crop performance, water use efficiency and economics for five years (2003–2008) in northwest India. Straw mulch reduced the maximum soil temperature at seed depth by about 3 °C compared to the no mulch. During the wheat emergence, raised beds recorded 1.3 °C higher soil temperature compared to the flat treatments. Both maize and wheat yields were similar under different treatments during all the years. Maize and wheat planted on raised beds recorded about 7.8% and 22.7% higher water use efficiency than under flat layout, respectively. Straw mulch showed no effect on water use and water use efficiency in maize. The net returns from the maize-wheat system were more in no tillage and permanent raised beds than with conventional tillage. Bulk density and cumulative infiltration were more in no tillage compared with conventional tillage.
