Effect of Organic Manures on yield attributes and grain yield of Maize in Tawang District of Arunachal Pradesh

Abstract

ABSTRACT

Afield experiment was conducted to study the effects of organic manures on yield attributes and grain yield of maize (Zea mays) during the kharif season of 2016 and 2017 at three villages’ viz. Lemberdung, Khinmey and Changprong in Tawang district of Arunachal Pradesh. The experiment consisted of four treatments of organic manures viz. control, farmyard manure (F.Y.M) @ 8.0 t/ha, Vermicompost @ 3.0 t/ha and FYM @ 4.0 t/ha+vermicompost @1.5 t/ha. Results conferred that the highest grain yield (53.0 q/ha) was observed in treatment FYM @ 4.0 t/ha + vermicompost @ 1.5 t/ha as compare to other treatments. Similarly, the highest number of cob/plant (2.0), length of cob (14.0 cm) and grain/cob (235) were recorded with the application of F.Y.M. @ 4.0 t/ha+ vermicompost @ 1.5 t/ha as compared to sole application of all other three treatments i.e. F.Y.M @ 8.0 t/ha, vermicompost @ 3.0 t/ha and control. Application of Farm yard manure and vermicompost in maize proved economically superior and ecological viable in improving the maize grain yield.
