The investigation was concerned with the effects of water stress on the yield and yield components of wheat grown under rainfed conditions in Rawalakot, Pakistan. A pot experiment was conducted with four wheat genotypes, Inqlab-91, Chakwal-97, Rawal-87 and Kohsar-95, tested against five irrigation levels with drought imposed at different growth stages including control, terminal drought, post-anthesis drought, three irrigations and pre-anthesis drought. The parameters studied were flag leaf area, ear stalk length, number of grains per spike and grain yield per pot. Flag leaf area and ear stalk length exhibited a significant reduction of 14 and 36%, respectively, when wheat was subjected to water stress. The proportional reduction in yield was 40% with three irrigations and 98% in the case of pre-anthesis drought depending upon the extent and degree of stress. Results showed that wheat could withstand and tolerate drought only up to anthesis, after which water stress resulted in the complete failure of the crop. It could be deduced that the critical stage for moisture in wheat started 60 days after germination, and became more severe at 90 days, i.e. at the anthesis stage. Among the genotypes, Inqlab-91 was found to be more tolerant of drought and could thus be a good option for further testing and recommendation for rainfed areas.

Irrigation Treatments

The high demand of barley for animal feed and the scarcity of fresh water increase the need for the reuse of treated wastewater as an alternative source for irrigation. Therefore, two-field experiments were conducted to study physiological processes, plant growth, grain yield and yield components of four-barley cultivars grown under four-irrigation treatments using treated wastewater or fresh water. Plants of four-barley cultivars (ACSAD176, Rum, Athroh, Yarmouk) were exposed to four-irrigation treatments: 1) Full-irrigation using treated wastewater (FWW); 2) Supplementary-irrigation using treated wastewater (SWW); 3) Supplementary-irrigation using fresh water (SFW); 4) Non-irrigation treatment (Rainfed). Full- or supplementary-irrigation using treated wastewater reduced stomatal resistance and increased plant photosynthetic rate, plant height, grain yield and yield components as estimated by grain number plant-1 and 1000-grain weight compared with rainfed conditions. Plants grown under supplementary-irrigation using treated wastewater produced higher grain yield than those grown under supplementary-irrigation using fresh water. Rum cultivar had the highest grain yield among cultivars grown under irrigation. Under rainfed conditions, Rum and ACSAD176 had the highest grain yield. In conclusion, supplementary-irrigation using treated wastewater improved grain yield of barley and can be a better choice to conserve water and reduce the risk of plant lodging at the end of the growing season. Irrigation barley using treated wastewater did not change heavy metal (Zn, Cd, and Pb) concentrations in soil or harvested grains.

This experiment was conducted to determine the effects of different sowing dates (5th October, 20th October, 5th November, and 20th November) and sowing depths (2, 4, 6 and 8 cm) on yield and some yield characters in two rowed barley (cv. Tokak 157/37) under rainfed conditions. The field study was conducted in Kirsehir ecological condition during 2014-15 and 2015-16 winter growing seasons. Grain yield and important yield traits such as plant height, spike length, number of fertile spike per square meter, number of grain per spike and grain weight per spike were determined. Sowing dates and depths influenced significantly the grain yield and yield components in two consecutive years. Most of the yield components were adversely affected by deeper sowing depths and delayed sowing dates. Based on two-year average, the highest grain yield was recorded with 2733 kg ha-1 at 20th October sowing date and 4 cm depth; in contrast the lowest grain yield was 513 kg ha-1 by the 20th November and 8 cm depth.
