The purpose of the research was determine the effects of gamma ray on seed germination, seedling height and root length of Rice (Oryza sativa L. spp. Indica cv. MR219) to identify the Lethal Dosage of the radiation. Paddy seeds of MR219 were exposed to different doses of gamma radiations viz 50,100,150,200,250,300,350,400,450,500,600,700,800,900 and 1000 Gy using 60Co as the radiation source. T...

allelopathic plants, because of reduction in herbicide uses, are important in weed management. the allelopathic effects of sage salvia officinalis and white wormwood artemisia sieberi water extract were evaluated on germination and seedling growth of redroot pigweed amaranthus retroflexus at concentration of 0, 5, 10, 15, and 20% in controlled conditions. anova revealed that the extract concent...

Drought significantly reduces yield of many crop plants including wheat in the world. Identification of wheat genotypes that can thrive on limited water is vital to boost the wheat production of rainfed areas. Forty wheat genotypes were screened for drought tolerance using 0, 7.5, 15 and 22.5% Polyethylene Ethylene Glycol 6000 solutions at PMAS Arid Agriculture University, Rawalpindi, Pakistan ...
