Production of G0 ‘Median’ Potato on Different Media Composition and Fertilizer Method

Abstract

Background and Objective: The G 0 ʻMedianʼ potato was designed to adapt in medium-altitude land and to produce seed tuber instead of food material. This study aimed to evaluate the growth and production of G 0 ʻMedianʼ potato under different media composition and fertilizer application methods in medium-altitude land. Materials and Methods: Two weeks old post acclimatization plantlet of G 0 ʻMedianʼ potato was prepared as plant material and then arranged in a split-plot design with two factors (growing media and chemical fertilizer application method) and three replications. Results: The result showed that the less proportion of soil in growing media could improve the field capacity, porosity, air space and water holding capacity, resulting in more loose structures suitable for potatoes (GM 1 >GM 2 >GM 3 ). The interaction of GM 1 +F 2 produced the significantly heaviest plant biomass (dry weight of plant and root). However, the best treatment was GM 2 +F 2 with the highest number of tuber per plant, i.e., 6 tuber per plant. Conclusion: High frequency (10x) of diluted granular fertilizer by using watering method (F 2 ) was suitable to improve not only the number of stolon and tuber but also the quality of harvested tuber as indicated by the lower percentage of small seed tuber.

Short Communication: Agronomical characteristics of sweet corn under different plant growth regulators during the dry season

“…Leaf was an important variable to be an appropriate proxy of plant growth (Salazar et al 2018;Hamdani et al 2022), morphological feature (Efendi and Budiarto 2022;Budiarto et al 2021a;2021b;Djarot et al 2021), phytochemical content (Efendi et al 2021), and physiological condition (Budiarto et al 2018;Budiarto et al 2019b). Leaf size, in terms of leaf length and width, of sweet corn at present proved to be significantly affected by the application of PGR.In theory, the application of GA3 was able to increase leaf length by increasing plant cell division and elongation, but higher doses of gibberellic acid inhibited leaf growth yielding shorter leaves (De Souza and MacAdam 2001; Utami et al 2018).…”

Comparative and Correlation Analysis of Young and Mature Kaffir Lime (Citrus hystrix DC) Leaf Characteristics

“…Leaf size is an important morphological character that has been frequently observed in numerous papers. The area of leaf is aimed to evaluate the accumulation of plant biomass [37] and also the leaf growth [38][39][40]. In addition, leaf size was also the basis for considering the suitability of ornamental citrus potted plant that is widely developed in green cities [41,42].…”
