Abstract

Culantro (Eryngium foetidum) can be found grow wild in some areas in West Java, one of them is in Cisarua, and it has been used for the community as salad. However, this indigenous vegetables rarely seen in vegetable markets in the area, since it is not cultivated. This need attention for its conservation and sustainability in the market. One of the efforts can be done is to cultivate them in the appropriate growth environment. Type of growing media and fertilizer are important aspects in vegetables cultivation. This research aimed to find the optimum combination of growing media with fertilizer dose for wild culantro vegetative growth. Based on the research, vegetative growth which measured by length and number of leaf cumulatively during observation 7 month after transplanting showed significantly different (α = 1%). The best vegetative growth obtained on the combination of husk charcoal media with 1000 ppm Grow More (32:10:10), resulting in length and number of leaf were 19,41 cm and 14,10 respectively.

Abstract

The objective of the research was to evaluate the effect of branch pruning and male flower thinning on growth and production of gherkin. The research was conducted in a plastic house at Pasir Sarongge Research Station of IPB, Cipanas, from December 1999 to February 2000. A Complete Random Design with two factors was used in this experiment. The first factor was branch pruning consisted of three intensity levels i.e. without branch pruning (CO), a part of branch pruning (CI), and total branch pruning (C2). The second factor was male flower thinning i.e. without thinning (BO), and with thinning (BI). Each treatment was replicated three times. Gherkin variety used in this experiment was SMR 58. The treatments were applied after el1lerging of male flower at 5 weeks after planting, and then it was replicated in every 3 days. Vegetative growth variables observed were length of stem and number of node per plant, while production components observed were number of female flower, number and weight of total fruit, and number and weight of marketable fruit. There was no interaction between branch pruning and male flower thinning treatments on all vegetative and generative variables. Both treatments did not show significant effect on vegetative growth as shown on stem length and node number. At the end of experiment (82 days after planting) the average of stem length was 230.4 - 247.6 cm and node number was 30.2 - 31.0 per plant. The treatments also did not show significant effect on production variable components, except for marketable fruit weight. Number of female flower was 19.0 - 20.3 per plant, while number of fruit was 15.2 - 16.3 per plant. The marketable fruit weight resulted from the total branch pruning treatment was 94% of the total fruit weight, showed significantly higher than that of the control plant (83%). There was a tendency for male flower thinning treatment to result higher marketable fruit as compared with that of the control ones. Key words..

Abstract

Pertumbuhan tomat pada lingkungan berbeda memberikan perbedaan hasil karena adanya interaksi genetik x lingkungan yang mempengaruhi ekspresi suatu gen pada kondisi lingkungan tertentu. Penelitian ini bertujuan untuk menduga nilai ragam genetik serta nilai heritabilitas arti luas pada genotip tomat tipe determinate di dua lingkungan tanam. Penelitian dilakukan dari Maret hingga Juli 2021 dengan menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) di dua lingkungan tanam (Depok dan Jakarta). Perlakuan terdiri dari 3 genotip tomat generasi F6 dan 2 varietas komersil diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa lingkungan tanam memberikan pengaruh terhadap pertumbuhan dan perkembangan genotip tomat yang digunakan. Nilai ragam genetik pada setiap karakter tergolong dalam kriteria sempit, kecuali pada karakter tebal daging buah dan luas daun. Nilai heritabilitas arti luas terhadap karakter yang diamati menunjukkan kriteria tinggi, kecuali pada karakter diameter buah (kriteria sedang) dan karakter tinggi tanaman (kriteria rendah). Genotip RwTa-4-10U-6U-4U-2U memberikan penampilan terbaik pada kedua lokasi tanam, dengan tinggi tanaman lebih rendah (91,09 cm), diameter batang lebih kekar (9,69 mm), buah lebih panjang (5,64 cm), diameter buah lebih besar (4,25 cm), total padatan terlarut lebih tinggi (5,22ºBrix), bobot per buah lebih besar (48,43 g), serta umur berbunga lebih genjah (25 HST) dibandingkan varietas Tantyna dan varietas Tora.ABSTRACTTomatoes growth in different environments give different results due to genetic x environment interaction that affect the expression of genes in a certain environmental condition. This study aimed to estimate the genetic variance and the broad sense heritability of determinate tomato genotypes in two growing environments. The study was conducted from March to July 2021, using a Randomized Complete Block Design (RCBD) in two planting environments (Depok and Jakarta). The treatments consisted of 3 genotypes of tomato generation F6 and 2 commercial varieties with 3 replications. The results showed that the environment affected the growth and development of the tomato genotypes used. The genetic variance was classified into narrow criteria except for flesh thickness and leaves area. The heritability value showed high value except for fruit diameter (medium) and plant height (low). The genotype RwTa-4-10U-6U-4U-2U gave the best performance at both planting locations, with lower plant height (91.09 cm), more harder stem diameter (9.69 mm), longer fruit (5.64 cm), larger fruit diameter (4.25 cm), higher total dissolved solids (5.22ºBrix), greater weight per fruit (48.43 g), and early flowering (25 DAP) compared to the Tantyna and Tora varieties.

Abstract

The appearance of the fruit, especially in terms of appearance and color, is an essential assessment for consumers. The physical quality of guava can be seen from the visual appearance of the fruit peel through image data and quantitative color degrees. This study aimed to determine the effect of harvest age on the visual appearance and peel color changes of crystal guava and organoleptic values of crystal guava peel color during storage.The factor studied was harvest age at 90, 100, 110, and 120 days after anthesis (DAA). Parameters observed were visual appearance through image data, brightness level (L), and degree of reddish-bluish (a*) and greenish-yellowish (b*) and color organoleptic score for 9 days of storage at room temperature. The results showed that the peel of the guava fruit at the age of 90 DAA was bright green compared to the peel of the fruit at the old age of 120 DAA, which had a slightly yellowish-green color. The harvest age of guava fruit significantly affects the level of L, degrees a* and b* of crystal guava peel starting on day 7 of 9 days of storage. The results of the color organoleptic test values can be maintained up to a score of 6 on the 5th day and close to a score of 2 on the 8th day of storage.
