Abstract

Mardhiana, Pradana AP, Adiwena M, Kartina, Santoso D, Wijaya R, Maliki A. 2017. Effects of pruning on growth and yield of cucumber (Cucumis sativus) Mercy variety in The acid soil of North Kalimantan, Indonesia. Cell Biol Dev 1: 13-17. In recent years, cucumber production in Tarakan, North Kalimantan only reaches 20 tons ha-1. In fact, cucumber production potential could reach 49 tons ha-1. Several factors that limit the low productivity of cucumbers in Tarakan are acid soil and cultivation techniques which are still limited. This study aimed to determine the effect of pruning on the growth and yield of cucumbers in acid soil in Tarakan. The study was conducted using Randomized Complete Block Design with the treatment of without pruning (P0), shoot of prunings on the main stem (P1), pruning of whole lateral branches above the third section (P2), and pruning of 2 lateral branches that emerged first above the third section (P4). The results showed that plant height was 16.17% (P1) and 2.26% (P2) lower also 0.13% higher (P3) than the control (P0). The highest number of leaves was found in treatment P1 (16.19%) compared to P0. The best fruit diameter was also found in P1 treatment with 4.93% difference compared to P0. Furthermore, a highly significant and the best result on weight per fruit were also obtained by P1 treatment. The results showed that the fruit weight of P1 treatment (11.39%) was higher than P0. This study provided new information that the pruning treatment of shoots on the main stem of cucumber variety Mercy in acid soil could increase the diameter and weight of cucumber.

Effect of Apical Cutting on Roselle (Hibiscus sabdariffa L.) Production in Niger

“…According to Kabir [16], cutting apex produces the maximum amount of fruit and good quality. Similar results were revealed by [17] in tomato (Solanum esculentum L.), Slamet et al [18] in Roselle (Hibiscus sabdariffa L.), Mardhiana et al [19] in cucumber (Cucumis sativus L.), and Shilpa and Priyanka [20] in okra (Abelmoschus esculentus (L.) Moench).…”

“…The height of the apex showed a substantial effect on the number of capsules per plant [21,22,19] indicated that the number of capsules per plant was higher in cut plants of okra. In addition, Ahmed and Oladiran [13] have shown that the apex cut increases the number of pods per plant of okra (Abelmoschus esculentus) by 10 to 40%.…”

“…Auxin is responsible for apical dominance, which limits the growth of the lateral branches [25]. When the apex is cut, the plant redistributes this hormone to the side branches thereby promoting their development [19]. As a result, each secondary stem will act like the main stem by developing the main apex and underneath will start from the new secondary stems, producing several other secondary branches, afterward capsules, thus improving the final yield [12].…”

Influence of Apical Cutting on Growth Parameters of Roselle (Hibiscus sabdariffa L.) in Two Agro-climatic Zones of Niger

“…This could be attributed to the plant growth processes disruption caused by apex cutting. This could be also explained by the delay in plant growth (for a certain period) caused by apex cutting before the emergence of new shoots [19]. This result is in line with that of [26] Olasantan on the squash (Cucurbita maxima Duch.…”

Effect of Pruning and Fertilizers on Growth, Flowering and Yield of Cucumber (Cucumis sativus L.) under Protected Structure in Panchthar, Nepal

“…Mardhiana et al, 2017). Similarly, all three fertilizer combinations (30 Mt/ ha FYM +100 % RDF of NPK, 9.4 Mt/ha vermicompost + 100% RDF of NPK and 4.3 Mt/ha Poultry manure + 100% RDF of NPK) recorded statistically similar and superior result i.e.…”
