“…Inoculation of sweet corn seeds with Azospirillum brasilense in association with nitrogen fertilizer may be an agronomic alternative for increasing crop yield and net income of growers. Numoto et al [195] demonstrated that different rates of inoculation of sweet corn with Azospirillum brasilense integrated with nitrogen fertilization management improved phenotypic traits in summer growing periods, under supplemental irrigation. Furthermore, nitrogen fertilizer increased all the traits except kernel total sugars.…”

Modern sweet corn is distinguished from other vegetable corns by the presence of one or more recessive alleles within the maize endosperm starch synthesis pathway. This results in reduced starch content and increased sugar concentration when consumed fresh. Fresh sweet corn originated in the USA and has since been introduced in countries around the World with increasing popularity as a favored vegetable choice. Several reviews have been published recently on endosperm genetics, breeding, and physiology that focus on the basic biology and uses in the US. However, new questions concerning sustainability, environmental care, and climate change, along with the introduction of sweet corn in other countries have produced a variety of new uses and research activities. This review is a summary of the sweet corn research published during the five years preceding 2021.

“…Regarding the number of applications of Azospirillum, we found that two applications are the best treatment for maize inoculation; for De Souza et al (2019), the application of 30 kg ha -1 of N at sowing and a single application of 150 kg ha -1 , or two applications of 75 kg ha -1 in topdressing, inoculated with Azospirillum brasilense provided better nutrition and development, with a positive effect for the mass of 100 grains which reflects an increase in grain yield, similarly as we found in the research. Also, the application dose of Azospirillum was important as found by Numoto et al (2019) who suggested that the dose of inoculant that provided the best agronomic result was 100 mL ha -1 in conjunction with the application of N at sowing or top dressing and as we found, in relation to Azospirillum application, that best performed when it considered two inoculations to maize foliage, for some characteristics such as ear weight, grain weight and ear length per plant.…”

The objective of this investigation was to evaluate the effect of inoculating Azospirillum sp. and two levels of nitrogen on the productive characteristics of hard yellow corn variety 'Insignia 800' under the conditions of Nuevo Imperial, Cañete (central coast of Peru). A randomized complete block design with five treatments and four replications was used in a field experiment using the commercial corn hybrid 'Insignia 800'. The treatments were two levels of nitrogen (90 and 180 kg N ha -1 ), plus one or two applications to the foliage of Azospirillum sp. (1.08 x 10 7 CFU per plant), and a control treatment (without inoculation). Ten agronomic variables related to productive traits were evaluated. Treatment comparison was executed with the Scott Knott test at the 5% significance level using the Infostat program. Inoculation with Azospirillum sp. did not significantly affect the grain yield per hectare, grain weight per plot, shelling percentage, grain depth, number of ears per plant and diameter of the cob, but it influenced significantly some productive traits such as cob weight per plot, grain weight per plant, cob diameter and ear length, as well as a high benefit-cost ratio due to inoculation. Inoculating the plant foliage with Azospirillum sp. had a significant effect and greater economic efficiency for some productive characteristics of the hard yellow corn cv. ´Insignia 800´, and did not significantly affect grain yield.

Dan pada intensitas cahaya yang tinggi biasanya berkorelasi positif dengan suhu, dan suhu akan mempengaruhi kerja enzim, untuk tanaman jagung manis suhu yang efektif untuk melakukan fotosintesis berkisar antara 30 -40 ˚C (Nahidah Bashir, 2012;Numoto et al, 2019;Subaedah et al, 2021).…”

This study examines the use of Urea Fertilizer on sweet corn plants and harvest time in an effort to increase production and quality. This study sought to identify the effect of giving various doses of urea fertilizer with harvest time and it was found that the interaction of fertilizer treatment with harvest time had a significantly different effect on sweet corn production. The study was conducted using a factorial randomized block design (RAK) with two factors, namely urea dose (P) consisting of 3 levels and harvest time (B) with 3 levels and 3 replications, so that there were 27 experimental units. Each experimental unit was taken 8 experimental samples. The data were analyzed using analysis of variance and continued with the 5% DMRT test. The treatment was given: P1 = Urea at a dose of 300 kg/ha P2 = Urea at a dose of 225 kg/ha P3 = Urea at a dose of 150 kg/ha and B1 = 12.00 WIB, B2 = 14.00 WIB, B3 = 16.00 WIB. The parameters studied were plant height (cm); Number of leaves (strands); Cob length (cm); Cob diameter (cm); and the level of sweetness (brix) and weight of cobs per bed. The implication that can be drawn from the results of this study is that the growth of sweet corn (plant height, number of leaves) and production (cob length, cob diameter, cob weight per sample, sweetness level) were not significantly different, the interaction of urea fertilizer treatment 150 kg/ha with a harvest time of 14.00 gave a significantly different effect on the weight of cobs per bed.
