“…Whereas the minimum plant height was found to be in Baby Pak Choi (8.80 cm), Hong Tae (14.07 cm) and Purple Lady Pak Choi (16.87 cm). There are several reports indicating variation with respect to plant height by several workers, Funda [8], Cho et al, [9], Purbajanti et al [10] and Ansari et al, (2018).…”

A study was conducted on the Varietal Evaluation of Pak Choi using ten different varieties at the Horticultural Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (Uttar Pradesh). This study was carried out to determine the most suitable cultivar of Pak Choi under the agro-climatic conditions of Prayagraj during the winter growing season in 2022. The observations were recorded on various growth and yield contributing characters. At the end of the research, it is evident that Pak Choi White Stem was found to be superior on the basis of growth, having the maximum plant height (22.57cm) and gross weight (133.75g). In terms of yield/ha (q), Pak Choi White Stem (70.67) and Desi Pak Choi (69.22) was found to be superior. In terms of economics, the maximum gross return per hectare was obtained by Pak Choi White Stem i.e. 212010 INR followed by Desi Pak Choi i.e.,207660 INR.

Percobaan dengan bertujuan untuk mempelajari pengaruh interaksi pemberian dosis pupuk nitrogen dan pupuk kalium terhadap pertumbuhan dan hasil tanaman pakcoy.Percobaan dilaksanakan dari bulan Juli sampai bulan Agustus 2020 di Desa Cibeureum Wetan, Kecamatan Cimalaka, Kabupaten Sumedang, Provinsi Jawa Barat. dengan ketinggian tempat 585 meter diatas permukaan laut, dengan pH tanah 5,3.Rancangan yang digunakan dalam percobaan adalah Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri dari dua faktor dan di ulang tiga kali. Faktor pertama adalah dosis pupuk Nitrogen (n) yang terdiri dari tiga Taraf yaitu : n0= 0 kg ha−1, n1= 75 kg ha−1, dan, n2= 150 kg ha−1, sedangkan faktor kedua terdiri dari tiga taraf adalah dosis pupuk kalium (k) yang terdiri dari tiga Taraf, yaitu k0= 0 kg ha−1, k1= 50 kg ha−1, k2= 100 kg ha−1. Hasil Percobaan menunjukan bahwa dosis pupuk Nitrogen dan dosis pupuk Kalium menunjukan adanya interaksi pada jumlah daun per tanaman umur 10 HST. Dari hasil percobaan dan analisis pemberian dosis N = 75 kg h−1 dan 150 kg h−1 menghasilkan produksi bobot segar terbaik.

“…Non-destructive leaf area measurement could be applied for a wide range of plants [42]. Leaf area estimation has been done in some species of the Brassicaceae family, i.e., pakchoi (B. campestris) [43], rapeseed (B. napus) [44], red cabbage (B. oleracea var. capitata), cabbage (B. oleracea var.…”

Tatsoi [Brassica rapa subsp. narinosa (L.H.Bailey) Hanelt] is a leafy vegetable with potential for cultivation in a riparian wetland ecosystem. The floating culture system has the advantage of ensuring a sufficient water supply in the growing substrate due to the continuous upward water movement caused by capillarity force. This study evaluated the responses of the tatsoi plant to split fertilizer applications under conventional cultivation and floating culture systems. The fertilizer treatments consisted of control (F0), single (F1), split into 2 (F2), split into 3 (F3) or split into 4 applications (F4). The results showed that early growth of tatsoi was better using floating culture than the conventional system. However, tatsoi adapted well to conventional and floating culture systems as long as sufficient nutrients were available. A single application of 6 g NPK fertilizer (16:16:16 v/v/v) at transplanting provided sufficient nutrients, as indicated by the number of leaves, total leaf area, canopy area, stem dry weight, and leaf dry weight at harvest. The leaf SPAD values in the tatsoi plants were higher in the floating culture system than in the conventional system at 14 and 20 DAT fertilized with a 4-split application. Transplanting occurred 14 days after seed planting (DAP), and harvest occurred 49 days later. A quadratic regression model using leaf length (L), leaf width (W), or L×W as predictors was reliable for non-destructive leaf area estimation in the tatsoi plant. It is recommended for farmers to apply a single NPK fertilizer at the rate of 6 g/plant to achieve an optimum yield in tatsoi cultivated using a conventional or floating culture system. HIGHLIGHTS Tatsoi plant grew well under conventional and floating culture systems as long as sufficient nutrients were available Splitting fertilizer into several times of application did not significantly better than single application of NPK fertilizer at time of transplanting SPAD values in the tatsoi leaves were higher in the floating culture than in the conventional system Length and width of leaves were reliable predictors for non-destructive accurate leaf area estimation in the tatsoi plant GRAPHICAL ABSTRACT
