  The effect of atrazine on the levels of carbohydrates, amino acids, potassium, phosphate and sodium contents in shoots and roots of bean plant were investigated. Application of atrazine amounting, 10 to 100 ppm resulted in decrease in carbohydrate, potassium, phosphate and sodium contents of roots and shoots of bean plants. However, amino acid content was reduced in shoot as compared to root wherein it got enhanced at 10 to 100 ppm atrazine concentration. A little growth stimulant effect was observed at 5 ppm concentration of atrazine in shoots and roots of bean plants.

  Studies were undertaken to find out the hest source of carbon and nitrogen for the best growth of fungus Phytophthora capsici and its biological control. Different organic soil amendments were used against P. capsici. The best source of carbon and nitrogen were sucrose and ammonium nitrate respectively. Neem was the must effective organic source in reducing the number of propagules of the fungus.

  The study deals with a series of experiments to investigate absorption of radioactive phosphate from different parts of young Triticum aestivum L. (wheat variety Sutlej-86) plants. Considerable transport of P32 occurred when the labelled phosphate was fed through roots. The plants showed considerable variation in the rate of absorption and translocation of P32 with respect to time. Absorption through leaves was found at a lower level compared to roots. Downward movement of P32 was minimal. Therefore it can be concluded that only root has the capability to provide feeding route for plant.
