“…There were significant effect of planting systems and plant populations on leaf area index, net assimilation rate and double row spacing resulted in statistically higher yield than single row spacing. Akbar et al (2016) showed that, narrow spacing (75 cm × 25 cm) and double row spatial arrangements increased radiation interception of maize plants by 16 to 24% and maize grain yields increased by 15 to 26% compared to wide (90 cm × 30 cm) and single row spatial arrangement. Serita (2015) worked on maize (Zea mays)-squash (Cucurbita moschata) intercropping at different plant population (squash density of 30%, 40% and 50% of total maize population) and showed that LER values decreased as squash population density increased.…”

The competitive behaviors of maize–squash intercropping at different planting systems were studied at Regional Agricultural Research Station, Hathazari, Chittagong, Bangladesh during the Rabi season of 2016–17 to find out the suitable planting arrangement of maize–squash intercropping for maximum productivity and economic return. There were seven treatments i.e. T1= sole maize, T2= 1 row maize (100%) + 1 row squash (6 plants/row), T3= maize paired row (100%) + 1 row squash (5 plants/row), T4= maize paired row (100%) + 1 row squash (4 plants/row), T5= maize paired row (100%) + 2 row squash (5 plants/row), T6= maize paired row (100%) + 2 row squash (4 plants/row) and T7= sole squash. Results revealed that the Maize Equivalent Yield (MEY) was highest (18.39 t/ha) in T5treatment, where Maize paired row (100%) + 2 row squash (5 plants/row) was consummated. The highest Land Equivalent Ratio (LER) 1.62 was found in T5 treatment. Benefit-Cost Ratio (BCR) was also the highest (3.29) in T5 treatment. Maize paired row (100%) and two rows of squash (5 plants /row) was the suitable row arrangement of the intercrops for judicious use of land consisting optimum populations of the component crops to produce more yield and economic profitJ.

“…Results presented in Table 7 indicate that the highest grain yield (8.62 t ha -1 ) was obtained with S 2 where the lowest (7.30 t ha -1 ) was with S 1 . Generally grain yield increased with increasing planting density reported by Akbar et al [7]. Badr and Othman [28] also stated that grain yield was affected significantly due to the interaction of plant densities Different chemical and organic fertilizers exerted significant variation on grain yield of maize.…”

“…The yellow maize production of Bangladesh increased from 3,000 tons in 1968 to 3.03 million tons in 2017 growing at an average annual rate of 28.35% [6]. Among the agronomic managements, setting optimum population density using the correct planting configuration and application of balanced fertilizers are two of the important agronomic operations [7]. Moreover, as the application of chemical fertilizers pollutes land and reduces the quality of soil, it is also advised to apply integrating the chemical fertilizer along with the organic fertilizers as the later improves soil physical as well as chemical properties and create favorable situation in the soil for crops growth and yield [8,9].…”

An experiment was conducted during December, 2017 to May, 2018 at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka to evaluate the performance of white maize variety under different spacing and integrated fertilizer management. The experiment comprised two different factors; (1) two plant spacing viz. S1 (60 cm × 20 cm) and S2 (40 cm × 20 cm) and (2) four levels of integrated fertilizer application viz. T1: All chemical fertilizer (recommended dose), T2: maize straw compost +½ of recommended dose,T3: cowdung+½ of recommended dose and T4: vermicompost +½ of recommended dose. The experiment was set up in split plot design with three replications. Results revealed that both the individual and the interaction treatments had effect on different growth and yield parameters of white maize. In respect of the spacing effect, the wider spacing S1 showed higher plant height, number of leaves plant-1, cob length, cob circumference, number of grains cob-1, shelling percentage, 100 grains weight and harvest index where S2 showed higher grain yield. The integrated fertilizer had significant effect on different growth and yield parameters of white maize. In respect of the integrated fertilizer effect, the highest values in plant height, number of leaves plant-1, leaf area index and crop growth rate, cob length, cob circumference, number of grains cob-1, shelling percentage, 100 grains weight, grain yield, stover yield and biological yield were highest with T3 whereas, the lowest corresponding values were recorded from T2. Among the interaction treatments, higher seed yield was obtained with the interaction treatment S2T3 (10.01 t ha-1) while S1T2 showed significantly the lowest seed yield (5.27 t ha-1). The highest seed yield was mostly attributed to the number of grains per cob (328-433) and 100 seed weights (29.67-33.33 g).

“…In response to increasing food demand farmers expanded wheat production in the region during dry season; but yield decline due to rising temperature and incidence of diseases caused reduction of area and production of wheat in recent years giving way to maize. Now maize is planted as an important cash crop to over 0.47 million ha producing about 3.1 million tons annually (BBS, 2018).While maize is planted in dry season in major growing areas in northern Bangladesh, it is grown in the CHT throughout the year (Akbar et al, 2016). Either in the plains or in the hills maize grain yield in Bangladesh is fairly high that ranges between 5.5 tons to 11.5 tons per ha across locations and seasons (Islam, Mahfuz, Sarker, Ghosh, & Ali, 2014;Akbar et al, 2016).…”

Planting date effect on phenological development, temperature accumulation and grain yield of maize was evaluated at three locations of Bangladesh differing in environmental conditions. Marked variations were observed in days to attaining phenological stages, temperature accumulation, duration of growth stages and grain yield across locations and planting dates. October planted maize in Bandarban completed its life cycle in 116 days while February planted maize in Kaharol suffered from high temperatures. December planted maize in Birganj experienced cool weather in vegetative phase and nearly optimal temperatures during reproductive phase. High temperatures hastened maturity reducing the duration of reproductive growth. Early planted maize produced the highest grain yield. Higher grain yield was positively related with the duration of reproductive growth phase. Late planting reduced maize grain yield mainly through lowering the number of kernels per ear and reducing kernel weight.
