“…Increased application rate of isoxaflutole has been directly related to maize injury and decreased shoot height (Sprague et al 1999a). Visual symptoms, plant height and shoot and root dry weight reductions are parameters that have been recommended to assess herbicide toxicity (Ibrahim et al 1987, Hassan 1988, Kaur et al 2004, for example, isoxaflutole alone and with metolachlor/benoxacor and acetochlor/MON-13900 on maize (Sprague et al 1999b). In this study, shoot height measurement was taken as a bioassay parameter to assess isoxaflutole phytotoxicity.…”

Isoxaflutole at 75 g ai ha−1 is registered in Australia for the control of several broadleaf weeds in chickpea (Cicer arietinum L.). Although isoxaflutole provides satisfactory control of problematic weeds, under certain conditions crop injury can occur. Higher air temperature and moisture content of soil are reported to affect the metabolism of soil applied herbicide. Controlled environment experiments were used to determine the tolerance of chickpea to isoxaflutole under a range of temperature and soil moisture levels. For the soil moisture study, the variables examined were two desi chickpea genotypes (Kyabra as a tolerant cultivar and Yorker as a sensitive cultivar), three soil moisture levels [50 % field capacity (FC), 75 % FC and FC] with three herbicide rates [0, 75 (recommended rate) and 300 g ai ha−1]. For the temperature by soil moisture study, the variables examined were two other desi chickpea genotypes (97039‐1275 as a tolerant line and 91025‐3021 as a sensitive line), three temperature regimes (20/5, 30/15 and 35/25 °C), two soil moisture conditions (50 % FC and FC) with the same three herbicide rates. The results demonstrated that the chickpea genotypes exhibited differential tolerance to isoxaflutole, but that differences in response were affected by rate, temperature and soil moisture. Increasing temperature and soil moisture content made the susceptible chickpea genotype more vulnerable to isoxaflutole damage. Injury to the susceptible genotype in terms of increased leaf chlorosis and reduction in shoot height and dry matter production increased as soil moisture increased from 50 % FC to FC and temperature increased from 20/5 to 35/25 °C. Overall damage of the sensitive genotype from increasing rates of isoxaflutole also increased when soil moisture content increased from 50 % FC to FC within the fixed temperature regime of 30/15 °C. The sensitivity of chickpea to isoxaflutole depends on existing temperature and moisture content and the chances of crop damage were enhanced with increasing temperature and moisture levels.

“…Canola (rapeseed) is one of the oil crops , which contains more than 40% of oil . In Egypt , rapeseed is of recent production but has bright future because of its ability to grow in the new reclaimed lands under wide soil variations as drought and salinity as revealed by some investigations carried out under Egyptian conditions (Ibrahim, et al 1987).

Field experiments were conducted at EL -Serw Agricultural Research Station (North Delta) in the two growing seasons 1997-1998 and 1998 -1999,to study the effect of number of irrigations and nitrogen rates on and the Canola yield,its components , water consumptive use, water use efficiency , and crop coefficient. Pactol cultivar was used in this experiment .A split -plot design with four replications was used . Four irrigation treatments (I1 = five irrigations, I2=four irrigations ,I3= three irrigations and I4 =two irrigations ) in the main plots and four N-fertilizer levels (N1= 75kg N/fed , N2 =50 kg N/fed, N3 =25kg N/fed and N4 = zero kg N /fed )in the subplots were tested . Results indicated that there was significant effect for the treatments on Canola seed yield and its yield components . Seed yields for I2,I3 and I4 (four ,three and two irrigations) , respectively were 15 .9% ,27 % and 41% less than the yield of I1 (five irrigations )respectively . For the N-level of 75 . N kg /fed, seed yield was 14.6% , 51.2% and 65% more than the yield of N2, N3 and N4, respectively . The results showed also that there was a high significant effect for the treatments on yield components . Water consumptive use values were 34. 65 cm, 28.7cm , 20.6cm and 16.8 cm for irrigation treatment I1 ,I2, I3 and I4 respectively . Their values were 31.1 , 27.6 , 22.9 and 19.05 cm for N-rates 75, 50 ,25 and zero ( kg N/fed ), respectively . Water use efficiency for I1=five irrigations was 27.5 kg seed /cm water and the value was 39.3 kg/cm for 75 kg N/fed . Crop coefficient for Canola crop at North Delta area is 0.89 .

Indian mustard (Brassica juncea) is infested with a parasitic weed, Egyptian broomrape (Phelipancheaegyptiaca), threatening its production in south-western parts ofHaryana. Afield experiment was conducted to study the effect of broomrape control treatments on the growth rate, number of days to 50% flowering and siliqua initiation, primary branches, secondary branches and grain yield of Indian mustard. The crop growth rate, number of primary and secondary branches and the grain yield were higher when supplied with 125% of recommended fertilizer (N & P) + foliar spray of glyphosate at 25 and 50 g/ha + 1.0% solution of (NH4)2SO4 at 25 and 55 DAS, respectively. This was followed by foliar spray of glyphosate at 25 and 50 g/ha + 1.0% (NH4)2SO4 at 25 and 55 DAS, respectively. The broomrape control treatments had no significant effect the relative growth rate and number of days to 50% flowering.
