“…Grain yield was about 1.7 times lower in mid-maturity hybrid ZP 560 than in ZP 666, while early sowing treatments had about 1.3 times more grain yield than late sowing treatments (Table 2). In similar studies, Baum et al [38], Liaqat et al [39], Sab et al [40], and Ke and Ma [41] have also reported that early sowing treatments resulted in higher grain yields in late-maturity hybrids than in early-and mid-maturity hybrids. In addition, Liaqat et al [39] and Sab et al [40] have found an inconsistent effect of interaction between maize hybridity and sowing time for tested maize growth parameters.…”

Then, Baum et al [38] pointed out that the effect of hybrid maturity was lower compared to the sowing time on maize grain yield and phenology, explaining that hybrid maturity depended on climatic conditions in some of the localities.…”

Influence of Sowing Time on Fusarium and Fumonisin Contamination of Maize Grains and Yield Component Traits

et al. 2022

The main aim of this research was to study the effect of two sowing times (early and late) on Fusarium and fumonisin contamination and some yield component traits of two maize hybrids from the FAO maturity groups 500 (ZP 560) and 600 (ZP 666) within a two-year growing season (2016–2017). F. verticillioides and F. subglutinans have been identified as Fusarium ear rot (FER) pathogens and potential producers of B-type fumonisins (FBs), with F. verticillioides as the predominant Fusarium species in both years. The incidence of F. verticillioides and FB levels were affected by sowing time and maize hybridity. With early sowing and the mid-maturity hybrid ZP 560, F. verticillioides and FB contamination were lower than with late sowing and the late-maturity hybrid ZP 666. Yield parameters also differed significantly between sowing time and maize hybrid treatments. Early sowing increased ear length (EL), number of grains per ear (NGE), grain weight per ear (GWE), and grain yield per hectare (GY). The late-maturity hybrid ZP 666 had higher yield component traits and GY than the mid-maturity hybrid ZP 560. EL, GWE, thousand-grain weight (TGW), and GY were affected by year. Interactions between sowing times and maize hybrids were highly significant (p ≤ 0.01) for FB level, GWE, and GY. The obtained results indicate the importance of applying early sowing to achieve high maize grain yields with lower contamination by F. verticillioides and FBs. Although mid-maturity hybrid ZP 560 and late-maturity hybrid ZP 666 showed significant differences in terms of levels of F. verticillioides and FB contamination, both were susceptible to F. verticillioides, with high FB levels. These results should be useful to breeders of maize hybrids to create genotypes more resistant to these fungal contaminants.

“…The number of trifoliate leaves is a plant characteristic that affects the rate of photosynthesis to capture sunlight. Sab et al (2020) showed that a higher number of leaves would result in a higher plant dry weight. In this research, liquid organic fertilizers that are rich in nitrogen increased the vegetative growth including number of trifoliate leaves and dry weight.…”

Abstract. Pangaribuan DH, Ermawati, Suryani NMW, Maria WS. 2022. The growth and yield responses of two bean cultivars to organic and inorganic nitrogen sources. Biodiversitas 23: 1677-1682.The productivity of beans is increased by selecting the best cultivar and applying fertilizers according to the needs of the plant. In addition,the application of high-yielding cultivar and N fertilizers with the right dosage could be used to increase the yield. Therefore, the objective of thisstudy is to determine the effect of nitrogensources on the growth and yieldof two bean cultivars. A5×2 factorial treatment was usedin a randomized block design with three replications. The first factor is the Perkasa and Lebat-3 cultivar, the second is organic and inorganic nitrogen fertilizer, namely control, urea 100kgha-1, as well as 10, 20, and 30% concentrationsof liquid organic fertilizer from leucaena leaves. The results showed that the use of liquid organic fertilizers derived from leucaena could be used as an alternative to nitrogenfertilization. Furthermore,the 20% concentrationtreatment producedthe highest number of trifoliate leaves (8.81 leaves) and dry weight (4.52 g). Based on the results,the use of 20% liquid organic fertilizer withPerkasa cultivar showed the best effect on the number of pods per plant (13.38),and yield(846.67 kg ha-1). The technology of liquid organic fertilizers from leucaena leaves could be recommended for bean organic production.
