چکیده مقاله :
The effect of biofertilizers and plant density was investigated on yield and yield components of sweet corn
cv. ‘Sari 2802’ in a split-plot field experiment based on a randomized complete block design with three replications
in Lahijan, Guilan province in 2021. The main plot was assigned to biofertilizers at four levels of
control (F1), using N-Fertile 1 (F2), phosphate Fertile 2 (F3), and N-Fertile 1 + Phosphate Fertile 2 (F4), and
the sub-plot was assigned to plant density at three levels of 55,000 (D1), 65,000 (D2), and 75,000 plants/ha
(D3). The results showed that the application of biofertilizers influenced plant height, grain number per ear, ear
length, total dry matter, grain yield, and 1000-grain weight positively. The highest 1000-grain weight (383 g),
the highest total dry matter (26240 kg/ha), and the highest grain yield (9146 kg/ha) were obtained from F4D2
(N-1 + P-2 and the density of 65,000 plants/ha). The results showed that the density of 65,000 plants/ha and
applying N-1 and P-2 biofertilizers was the best treatment.
