“…This shows that the use of shade-tolerant varieties is essential for high productivity. In other words, it is necessary to use varieties that can grow, develop, and produce well under shade stress to optimize land use under tree stands (Syafii et al 2021).…”

“…Plant breeders develop new varieties by hybridization processes (Syukur et al 2023) to enhance productivity (Schroeder et al 2013). Hybridization is an appropriate strategy to increase the productivity and production of sweet corn (Syafii et al 2021). For example, Ertiro et al (2015) developed a hybrid sweet corn by breeding between pure parental lines to produce F1 generation with superior characteristics that can increase production.…”

Abstract. Utari VF, Chozin MA, Hapsari DP, Ritonga AW. 2023. Morphophysiological responses and tolerance of various sweet corn (Zea mays convar. saccharata) hybrids to shade stress. Biodiversitas 24: 4438-4447. Expanding lands for cultivating sweet corn (Zea mays convar. saccharata) is a strategy to increase its production. Yet, the available lands for sweet corn extensification might be those with existing tree stands with some extent of shading. Planting sweet corn under tree stands affects its growth and productivity since there is a reduction in light intensity, but some superior varieties might tolerate such stress. This study aimed to determine the growth, yield, and shade-tolerance levels of several sweet corn genotypes under shade stress. The experiment adopted a randomized complete block design consisting of two factors, namely shading (i.e. control or 0% shade and 50% shade) and sweet corn genotype (16 genotypes). The observed parameters included morphological traits (plant height, leaf number, leaf length, leaf width, and stem diameter), physiological traits (stomatal density and trichome density), yield attributes (cob weight with husks, cob weight without husks, cob length, cob diameter, and total soluble solid), and stress tolerance index (STI). The tested genotypes responded differently to shading. In general, 50% shade significantly reduced cob production, with an average decrease of more than 50% compared to the control. Commercial varieties, namely Exotic (G13), Talenta (G14), Paragon (G15), and Golden Boy (G16), had relatively higher STI values compared to the hybrids. Among the hybrids, the highest STI values were observed for genotypes resulting from the crosses SM7-8 × SM12-2 (G11) and SM11-6 × SM12-2 (G12). The results of this study recommend that commercial varieties can be cultivated under tree stands or low light intensity and can be used to develop high-yielding shade-tolerant sweet corn varieties.

Fertilizer is one of the inputs in plant cultivation that requires high costs. However, unfavourable soil conditions so that most of the nutrients contained in fertilizers cannot be absorbed by plant roots. The purpose of this study was to increase the availability of nutrients and plant growth by applying a mixture of biochar – coastal sediment with inorganic fertilizers on alluvial soil. The study was a single factor experiment arranged in a completely randomized design with five replications. Treatment consisted of A: without giving fertilizer, treatment B: giving inorganic fertilizer 100% of the recommended dosage, treatment C: inorganic fertilizer mixed with biochar and coastal sediment 75% + 25% fertilizer recommended dosage, treatment D: inorganic fertilizer mixed with biochar and coastal sediment 50% + 50% fertilizer recommended dosage and treatment, E: inorganic fertilizer mixed with biochar and coastal sediment 25% + 75% fertilizer recommended dosage and treatment F: inorganic fertilizer mixed with biochar and coastal sediment 100% recommended dosage. The application of inorganic fertilizer mixed with biochar and coastal sediment 100% recommended dosage was able to increase the availability of nutrients P, K, Mg and growth of corn plants in Alluvial.

The introduction of superior grain corn genotypes with high and stable yield (YLD) in most environments is important to increase local production and reduce dependency on imported grain corn. In this study, days to tasseling (DT), plant height, and YLD of 11 grain corn genotypes were observed in 10 environments to evaluate the effects of genotype (G), environment (E), and genotype by environment interactions (GEI) using GGE analysis and the stability of genotypes using stability parameters. In each location, grain corn genotypes were arranged in three replications using a randomized complete block design. An analysis of variance showed that all three traits were highly significant toward G and E factors, whereas GEI showed that only DT and YLD were highly significant. Genotype V14 produced the highest YLD of 10,354 kg/ha, followed by V4 (10,114 kg/ha) and V2 (9797.74 kg/ha). These three genotypes also dominated in seven out of 10 tested environments. With regard to stability ranking, genotype V4 was the most stable genotype, with a big gap difference between the second (V14) and third places (V2). Therefore, V14, V4, and V2 were the most promising genotypes because of their great YLD performance and most stable across tested environments, which can be recommended to farmers for high-scale planting.
