The present investigation was undertaken to examine the effect of suitable spacing technique(s) of maize on the morpho-physiology, yield attributes, yield and nutrient composition of maize at the Entomology Field Laboratory, Department of Entomology, Bangladesh Agricultural University (BAU), Mymensingh during Rabi season of 2016-17. The research work was carried out in randomized complete block design (RCBD) with three replications. Maize var. BARI Hybrid Butta-09 was used as the test crop. Five spacing techniques (Distance of row to row and plant to plant, respectively were 50cm×20cm (T1), 55cm×25cm (T2), 60cm×30cm (T3), 65cm×35cm (T4) and 70cm×40cm (T5). All the spacing techniques showed significantly different performance on yield. It was revealed that the maximum morpho-physiological characters, yield attributes and yield was obtained with higher composition of nutrients by using technique of 60cm×30cm (T3). This treatment also showed the highest plant height (223.45cm), stem diameter (8.10cm), leaf length (74.25cm), number of cob plant-1 (1.74), cob length (22.20cm), number of grain cob-1 (710.13), grain weight cob-1 (230.67g), grain yield (10.11 t ha-1), protein content (10.45g), fat (3.46g), carbohydrate content (65.42g) and vitamin C (0.12g). Furthermore, based on yield of maize and nutrient composition, the increasing order of yield was S2>S4>S1>S5. Therefore, considering all facts, 60cm×30cm as the technique of spacing could be recommended to grow maize for obtaining higher yield quality. 

KeywordsSpacing techniques, morpho-physiological characters, yield attributes, nutrient composition and maize yield.
