Abstract
Seed quality plays an important role in the crop establishment and overall performance of the crop.
Keeping in view, the importance of quality seed, the experimental material for present research comprised of four
genotypes of coriander viz. DH-5, DH-36, DH-228 and DH-246 were grown with three replication in factorial
RBD to study the “effect of foliage cuttings and growth regulators on seed yield and quality of coriander”. The
foliage cutting was taken to make different treatments i.e. C0 (without cutting), C1 (one cutting at 45 days after
sowing) and C2 (two cuttings at 45 days and 60 days after sowing) and foliar application of plant growth regulators
at 50 percent flowering were done in all cutting levels. The investigation resulted that number of foliage cuttings
reduced the plant growth, seed yield and quality. The crop without cutting of foliage gave the maximum plant
growth along with highest seed yield and quality which was followed by one cutting and lowest performance was
observed after two cuttings. The application of NAA (50 ppm) at the 50 percent flowering after foliage cutting
enhanced the plant growth, seed yield and quality followed by GA3 as compared to control (water). Among
laboratory parameters standard germination, test weight and seedling length were best predictor of field
performance as these parameters exhibited high positive correlation with field emergence. The genotype Hisar
Anand (DH-5) was found best seed producing genotype. Whereas, Hisar Bhoomit (DH-228) was found dual
purpose genotypes both for foliage and seed.
