Effect of different organic inputs and transplanting dates on seed quality parameters of radish (Raphanus sativus L.)
An investigation was carried out during two consecutive years (2014-15 and 2015-16) at experimental farm of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan-273230 (H. P.). The experiment was conducted on effect of different organic inputs like vermicompost, FYM, Azotobactor, PSB and PGPR and transplanting dates on seed quality attributes of radish (RaphanussativusL.). The transplanting was done on three different dates during both years. There were seven treatments including control and each treatment was replicated thrice. The data was analysed in factorial randomized block design. The study revealed that all the seed quality parameters like germination % (95.08), seedling length (24.46 cm), shoot length (13.02 cm), root length (13.04 cm), seedling dry weight ( 0.110 mg), seed vigour index I (2329.07) and seed vigour index II (10419.25) were found maximum with treatment Vermicompost (@ 50 q ha-1) + Azotobacter (root dip @ 2.5 Kg/ ha-1) + PSB (root dip @ 2.5 Kg/ ha-1) + NSKE (5 %) and maximum 1000 seed weight (12.52 g) was found with treatment FYM @100 q ha-1 + Azotobacter @ 2.5 kg ha-1 (root dip) + PSB @ 2.5 kg ha-1 (root dip) + NSKE @ 5 % in 4th November transplanting. All parameters showed a decreasing trend as sowing date was delayed.
