Sudden Decrease

Drought conditions in the western United States have limited water availability for the irrigation of agricultural products. This can have a dramatic impact on yield and quality of specialty perennial crops, such as juice grapes (Vitis labruscana Bailey). Washington State juice grape industry typically irrigates to 100% of crop-specific evapotranspiration (ETc) throughout the season to minimize yield loss. However, as conditions have limited water availability, growers need a new strategy to cope with the limited water supply. Regulated deficit irrigation (RDI) applies less water than plant ETc and has been shown to improve fruit quality in red wine grapes (Vitis vinifera). The objectives of this study were to evaluate the effects of RDI treatments on the yield and quality of ‘Concord’ juice grapes as compared with current commercial practice. The treatments reduced the amount of water applied between bloom and veraison by 25% (−25%), 33% (−33%), and 45% (−45%) from the control application. The results of this 4-year study initially indicated a dramatic decrease in yield in the −45% treatment (7.5 Mg/ha) as compared with the control treatment (19.2 Mg/ha); however, yield for the RDI treatments recovered in the subsequent seasons and was not statically different from the control. There were no statistical differences in fruit quality between treatments. This indicates that RDI has the potential to decrease water applied between bloom and veraison without impacting fruit quality; however, to avoid a sudden decrease in yield, it would be necessary to gradually reduce water applications over several years.

Crop demands for irrigation require different technologies to optimize the use of water. Regulated Deficit Irrigation (RDI) is a strategy that enables a significant reduction of water application without affecting the crop yield and quality, with the advantage of being a tool for control of vegetative growth. The present study was conducted in Sesquile, Cundinamarca (Colombia) between 2015 and 2016. The objective was to evaluate the quality and development of pear crop (Pyrus communis L. cv. Triumph of Vienna) on field conditions, using three treatments of 100%, and 25% of water requirement (ETc) and no irrigation, applied at the rapid fruit growth stage. The mid day stem water potential, plant water relations, pressure-volume curve, fruit yield and quality were evaluated. There were no significant differences in the yield and quality of the fruits among the different irrigation treatments. The trees had the mechanisms of osmotic adjustment, which allowed water stressed trees to cope with irrigation restrictions during the rapid fruit growth stage without affecting the yield.

ABSTRACT: Parthenium is an important weed which poses severe threats to yield and quality of sorghum and many other summer season crops, worldwide. As in other field crops, parthenium also reduces yield and quality of forage plants in forage crops so it should be controlled in forage and fodder crops. Parthenium control efficacy of five herbicide treatments (including dicamba at 304.5 g a.i. ha-1 (full rate) alone, dicamba at full rate + 1% ammonium sulphate, dicamba at full rate + 2% ammonium sulphate, dicamba at 75% rate + 1% ammonium sulphate and dicamba at 75% rate + 2% ammonium sulphate) was tested in field trials for two consecutive years (2013 and 2014). One manual hoeing three weeks after crop emergence was also performed as a treatment and weedy check was kept as control. Application of the full rate of dicamba with 2% ammonium sulphate showed the lowest parthenium dry weight (16.5 g m-2 and 23.5 g m-2) and NPK uptake that seem to be due to the highest parthenium control efficiency of 79.6% and 73.8% during 2013 and 2014, respectively. This weed management strategy also gave maximum values of yield components of forage sorghum, including plant height (261 and 254 cm), stem diameter (0.97 and 0.84 cm), leaf area per plant (3,072 and 3,041 cm2), fresh fodder yield (63.4 and 60.9 t ha-1) and dry matter yield (17.4 and 15.8 t ha-1) in 2013 and 2014, respectively. Highest net return and marginal rate of return (346 and 356% in 2013 and 2014, respectively) were also found when the full rate of dicamba with 2% ammonium sulphate was applied. In conclusion, tank-mixed application of dicamba at 304.5 g a.i. ha-1 with 2% of ammonium sulphate proved to be better for efficient control of parthenium weed in forage sorghum.
