Effect of Foliar Application of GA3, on Biochemical Changes of Indian Mustard [Brassica juncea (L.) Czern. & Coss.] under Sodic Soil

Abstract

The investigation on effect of foliar application of GA3, on biochemical changes of Indian mustard under sodic soil, was conducted during the rabi season, at the Main Experiment Station Farm of ANDUAT, Kumarganj, Ayodhya-224229 (UP) in randomized block design with 8th treatments, three replications & variety Narendra rai (NDR-8501). Different concentrations of GA3 (15ppm, 30ppm, 45ppm, 60ppm, 75ppm, 90ppm, 125ppm) were taken along with Distilled water control. Foliar spray was done at 30 Days after sowing. Observations to be recorded at 40, 60, 80 days after sowing of biochemical parameters like chlorophyll content, nitrate reductase, peroxidase, and catalase activities in green leaves were taken. Sprayed of different concentrations of GA3 increased all characters of the crop. All the parameters viz. To the studies of biochemical parameters were high recorded with foliar spray of GA3 125ppm followed by foliar spray with GA3 90ppm over rest of the treatments together with control, during the analysis.

Modulating Effect of PGRs on Growth and Biochemical Traits in Rice (Oryza sativa L.) under Salt Stress

“…27.65 % and 28.03 % respectively. This finding is according to, [10] reported in rice and in mustard [11].GA3 is one important plant hormones that regulate various processes of plant growth and development, which is particularly important in stem elongation. GA3 application, the height was increased significantly under salinity condition [12].…”

“…18.81 % & 30.82 % at 60 & 90 DAT respectively. Similar observation was also reported [13,11,15,14].The increase in plant dry weight due to foliar spray GA3 indicated that the photosynthetic activity and efficiency of the leaves have been increased which contributed to dry matter production [7,11,16].…”
