Abstract
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.
Keywords: Spacing techniques, morpho-physiological characters, yield attributes, nutrient composition and maize yield.
