Yield of Several Local Upland Rice Lines

Abstract

Climate change brought on by global warming affects agricultural production, notably rice crops, and results in harsh weather. Because it is becoming harder to utilize the area of paddy fields, one effort that can be made to boost the national food supply is by improving and expanding the upland rice farming area. This study aimed to analyze and ascertain the upland rice lines in the area's production potential. The study was carried out on agricultural land in Tamarenja Village (Kalama backwoods), Central Sulawesi Province, about 200 meters above sea level, with latitudes of 00o26'51.5" South Latitude and 119o49'50.6" East Longitude. They began in August 2022 and continued through February 2023. Fifteen strains or varieties of upland rice were used in the study's Randomized Block Design (RBD), which was repeated three times to create 45 trial plots. These strains or varieties included Untad I, Untad II, Untad III, Untad V, Uva Buya, Kalendeng, Pulu Tau Leru, Jahara, Buncaili, Delima, Dongan, Konta Island, Tako, and Situ Bagendit. Plant height, leaf length, tiller number, productive tiller number, panicle length, number of grains/panicles, harvest age, the weight of 1000 grains, and production were among the variables recorded. The findings demonstrated that the Tako, Dongan, Pulu Tau Leru, Uva Buya, and Kalendeng strains produced better yields compared to the control variety.

Determining the Right Dosage of Inorganic Fertilizers to Increase Growth and Results Three Local Upland Rice Cultivars

“…The results also show that each cultivar has a different response to the given dose of inorganic fertilizer. This indicates that each cultivar has a number of genetics that are different from other cultivars so that different growth and yields can be seen between one cultivar and another at the same dose (Mustakim, et al, 2019;Samudin, et al , 2021;Chong, et al, 2021;Maemunah, et al, 2021) The results of the study (Nazirah and Damanik, 2015) found that there were differences in the characteristics of the three upland rice varieties, namely Impago 4, 5, and 8 when using the same dose of fertilizer, including the characteristics of plant height, number of panicles, and panicle length.…”

UJI SALINITAS PADI GOGO DENGAN MENGGUNAKAN BERBAGAI LARUTAN NaCl PADA FASE PERKECAMBAHAN

“…Padi gogo merupakan salah satu tanaman pangan yang mampu tumbuh dan berproduksi dengan baik pada lahan-lahan marginal. Peluang pengembangan padi gogo masih sangat banyak, mengingat banyaknya lahan-lahan marginal yang ada di indonesia seperti di antaranya ialah lahan yang memiliki kadar garam yang tinggi, (Mustakim, et al, 2021) Salinitas merupakan akumulasi garam terlarut dalam air tanah yang dapat menghambat pertumbuhan tanaman (Arzie, et al, 2015). Masalah salinitas menjadi salah satu faktor pembatas dalam meningkatkan produktivitas, sehingga dilakukan pengujian ketahanan pada berbagai kultivar padi.…”

“…Salah satu syarat mutu benih untuk mendapatkan sertifikat adalah memilki daya berkecambah ≥ 80% (Kartasapoerta, 2011). Perbedaan sifat masing-masing kultivar disebebakan oleh faktor genetik yang diturunkan dari masingmasing tetua yang berbeda, (Mustakim, et al, 2019;Samudin, et al, 2021).…”
