A field experiment was conducted during the Kharif season of 2013 at Agronomy Research Farm, School of Agricultural Sciences and Rural Development (SASRD) Nagaland University, Medziphema, to study the effect of organic manure and Azospirillum on productivity of maize (Zea mays L.) under the agro climatic condition of Nagaland. The experiment was laid out in RBD replicated thrice with seven treatments i.e. FYM @ 10 t ha-¹, vermicompost @ 5 t ha-¹, pig manure @ 5 t ha-¹, FYM @ 10 t ha-¹ + Azospirillum @ 20 g kg-¹ seed, vermicompost @ 5 t ha-¹ + Azospirillum @ 20 g kg-¹ seed, pig manure @ 5 t ha-¹ + Azospirillum @ 20 g kg-¹ seed and control. The plant height, number of green leaves plant-¹, stem thickness (cm), and leaf area index were recorded highest with application of FYM @ 10 t ha-¹ followed by FYM @ 10 t ha-¹ + Azospirillum @ 20 g kg-¹ seed. FYM @ 10 t ha-¹ has also produced highest yield attributing characters like cobs weight (120.51 g), number of grain rows (34.84), length of cob (15.29 cm), grain weight (81.66 g), grain yield(1.82 t ha-¹), straw yield (3.01) and B:C ratio 2.5.

Abstract


A field experiment was conducted during the Kharif season of 2013 at Agronomy Research Farm, School of Agricultural Sciences and Rural Development (SASRD) Nagaland University, Medziphema, to study the effect of organic manure and Azospirillum on productivity of maize (Zea mays L.) under the agro climatic condition of Nagaland. The experiment was laid out in RBD replicated thrice with seven treatments i.e. FYM @ 10 t ha-¹, vermicompost @ 5 t ha-¹, pig manure @ 5 t ha-¹, FYM @ 10 t ha-¹ + Azospirillum @ 20 g kg-¹ seed, vermicompost @ 5 t ha-¹ + Azospirillum @ 20 g kg-¹ seed, pig manure @ 5 t ha-¹ + Azospirillum @ 20 g kg-¹ seed and control. The plant height, number of green leaves plant-¹, stem thickness (cm), and leaf area index were recorded highest with application of FYM @ 10 t ha-¹ followed by FYM @ 10 t ha-¹ + Azospirillum @ 20 g kg-¹ seed. FYM @ 10 t ha-¹ has also produced highest yield attributing characters like cobs weight (120.51 g), number of grain rows (34.84), length of cob (15.29 cm), grain weight (81.66 g), grain yield(1.82 t ha-¹), straw yield (3.01) and B:C ratio 2.5.
