Abstract:
A field experiment was conducted during rabi season (Dec 2018-March 19) to study the effect of different organic manures on growth and yield of mustard (Brassica juncea L.) at the Research Farm of the Arunachal University of Studies, Namsai. This experiment comprised of 9 treatments and 3 replications and was evaluated in Randomized Block Design. The treatments consisted of two doses of farm yard manure, vermicompost and poultry manure ( @ 5 t and 10 t each), a combination of FYM, vermicompost and poultry manure (2 tonnes each), enriched compost (phosphate solublising bacteria, rock phosphate, azotobacter) @ 5 t/ha and an untreated control. The cultivar used was NRCHB101 mustard variety. The study revealed that application of different organic manures exerted significant variations in most of the growth parameters. Better growth and yield parameters in terms of plant height, number of primary branches per plant, days to 50% flowering, siliquae per plant, seeds per siliqua and yield per plot (4 m²) was observed by application of poultry manure @ 10 t/ha and this was found to be superior among all other treatments. The second-best results were obtained from plants supplied with vemicompost @ 5 t/ha and 10 t/ha.
