Adaptation of growth and yield of several hybrid corn varieties of Balitbangtan on dryland agroecosystems in young Albasia Forest Area

Abstract

Select varieties with high yields and adaptive to the environment are one way to increase corn productivity. The study aimed to determine the adaptability of the growth and yield characteristics of superior national varieties of hybrid maize to shade stress. The study was carried out in a community forest area, Kalices Village, Kendal Regency, from March-September 2020. The study was designed using a split-split plot randomized block design with treatments for each sub-plot: (1) shade blocks 0%, 20%, and 40%; (2) application of cultivation technology for plant management recommendations for Integrated Crop Management (PTT) and farmer recommendations; (3) Varieties JH-37, NASA-29, and existing farmer hybrids. Data were analyzed using variance; if they were significantly different, they were further tested by Duncan’s Multiple Range Test (DMRT) at the 5% level. The results showed that the highest adaptive capacity was obtained by local corn with a density of 20%. The local hybrid variety Bisi-18 showed the highest dry shelled yield at 5.9 t/ha, followed by Nasa 29 at 5.8 t/ha dry shelled, and the JH 37 variety at 5.2 t/ha dry shelled.

Morphophysiological responses and tolerance of various sweet corn (Zea mays convar. saccharata) hybrids to shade stress

“…Therefore, this study aimed to determine the morphophysiological responses of growth, yield, and yield components and the shadetolerance level of several sweet corn genotypes under shade stress. We hope that the results of this study help to clarify the findings of Jauhari et al (2022) on the selection of environment for shade-tolerant sweet corn varieties.…”

“…The critical light intensity for selecting shade tolerance varieties in many food crops is 50% shading, such as in rice (Song et al 2022), soybean (Bing-Xiao et al 2020, chili pepper (Masabni et al 2016), and tomato (Sulistyowati et al 2016). On the other hand, the critical light intensity for corn is at 20% shading (Jauhari et al 2022) because the relative productivity of the species varies at this level. However, at 40% shading, most crop species experience a significant decrease in production.…”

Kajian Komponen Ragam Genetik pada Populasi F2 Tanaman Jagung (Zea mays L.) di Lahan Kering

“…Total luas lahan kering di Indonesia yaitu sekitar 148 juta ha, dengan 76,22 juta ha (52%) sesuai dengan lahan pertanian (Abdurachman et al, 2008). Hal tersebut menunjukkan tingginya jumlah lahan kering di Indonesia yang dapat dimanfaatkan untuk dijadikan sektor pertanian atau areal tanaman terutama bagi tanaman jagung (Jauhari, et al, 2022). Tidak semua jenis varietas jagung dapat tumbuh dengan baik di lahan kering yang memiliki curah hujan yang rendah.…”
