College of Agriculture, Anand. In Part-1, ten bunch and eight spreading varities of groundnut were included separately to study the varietal behaviour, yield and yield parameters during summer 1981. Significant differences were observed with respect to yield and yield contributing parameters among bunch and spreading varieties. Among bunch varieties, highest pod yields was produced by G-201 (36.97 q/ha) followed by 27-5-1 (32.44 q/ha) and lowest was with JL-24 (19.83 q/ha). Non-significant differences were observed among bunch varieties with respect to oil content and protein content of kernel. Among spreading varieties, maximum pod yield was produced by c-208 (39.92 q/ha) followed by M-13 (39.06 q/ha) and lowest was with 39-7 (27.22 q/ha). Seed oil content differences were non-significant, whereas the differences in seed protein content were significant among spreading varieties and it was highest with M-13 (26.40 percent) followed by S-3 (25.73 percent) and lowest was with C-208 (21.35 percent).enAGRONOMY, AGRICULTUREA STUDYSTUDIES ON VARIETAL BEHAVIOUR AND EFFECTS OF SOME GROWTH REGULATORS ON GROWTH, DEVELOPMENT, YIELD AND CHEMICAL COMPOSITION OF CERTAIN VARIETIES OF GROUNDNUT (Arachis hypogaea L.)Thesis
