Effect of different time of transplanting and organic fertilizers on plant growth and seed yield parameters of radish (Raphanus sativus L.)

Abstract

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 time of transplanting, organic fertilizers and their interactions on growth and seed yield of radish (Raphanus sativus L.). 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 was revealed that all the growth and seed yield parameters like minimum days to 50% bolting (88.17 days) and days to 50% flowering (95.33 days), maximum number of branches plant-1 (12.82) and maximum number of siliqua plant-1 (488.03) were recorded with treatment vermi compost @50 q ha-1 + Azotobacter @2.5 kg ha-1 (root dip) + PSB @2.5 kg ha-1 (root dip) + NSKE @5% and siliqua length (7.15 cm), plant height (111.65 cm), number of seed siliqua-1 (6.35), seed yield plant-1 (20.11 g), seed yield plot-1 (301.60 g) and seed yield (881.04 kg ha-1) were recorded maximum with treatment RDF+ Malathion @0.05% in 4th November transplanting. All parameters showed a decreasing trend as sowing date was delayed. The study reveals that interactions of different transplanting and organic fertilizers had significant impact on all growth and yield parameters.
