Cucumber(Cucumis SativusL.)Growth and Nutrient ContentResponse to Applications of Leonarditeand Phosphorus Fertilizer

Abstract

Leonardite is a common mineral that contains a lot of organic matter. It may have a beneficial influence on plant growth and nutritional content. The objective of the present study was to determine the effect of four different leonardite doses (0, 20, 35, and 50 g kg-1), three different phosphor rates (0, 50, 100, and 150 mg kg-1P), on plant growth, and nutrient uptake of Cucumber (Cucumis sativusL.). plants. The experiment was conducted in a plastic house. Increasing the leonardite dose statistically increased the concentrations of N, P, K, Mg, Cu, and Mn in the cucumber leaves, but Zn content (34.711 a) mg kg-1of the leaves was significantly higher only with the (20 gm) of leonardite. The highest phosphor application (150 mg kg-1) increased leaf N, P, K, Ca, Mg, and Mn concentrations compared with the other three doses and also the leaf Zn levels statistically did not increase as the P applications increased from (control to 150 mg kg-1). Based on the number of fruits per plant, the best interaction among leonardite doses and phosphor rate were a combination of the (35gm×100 mg kg-1) increasing the numbers of cucumber per plant (48.000a).

Arthropod Population in The Canopy of Cucumber (Cucumis sativus L.) Plants in Talang Ilir Hamlet, Banyuasin Regency

“…Buah mentimun dapat dimakan langsung sebagai lalapan atau sebagai bahan makanan olahan seperti acar (Mallick, 2022), mengandung 95% air, 16 Kcal, 16% vitamin K, antioksidan, flavonoid, mineral dan vitamin (Patel & Panigrahi, 2019;Sari et al, 2021;Samad et al, 2022;Grumet et al, 2022). Beberapa penelitian sebagai upaya peningkatan produksi tanaman mentimun telah dilakukan seperti kajian tentang pengaruh pemupukan dalam sistem budidaya (Aritonang et al, 2018;Khoirunnisa et al, 2019;Sallam et al, 2021;Majeed, 2021;Fransisko et al, 2021;Gumelar & Wiguna, 2022;Padang et al, 2023;Handayani et al, 2023), dan penelitian mengenai serangga arthropoda yang terdapat pada budidaya tanaman mentimun (Azad et al, 2013;Painkra et al, 2019;Srinivas et al, 2022). Berdasarkan kajian tersebut diketahui bahwa faktor penyebab menurunnya produksi tanaman mentimun diantaranya serangan hama arthropoda.…”

“…Wallaca and Wallaca (1986) domatese ve buğdaya 5.8 ile 11 t/ha leonardit uygulamışlar, domatesin veriminin arttığını, fakat buğdayın verim ve kuru madde miktarında önemli bir artış olmadığını rapor etmişlerdir. Salatalık bitkisine 0, 20, 35 ve 50 g/kg leonardit uygulayan Majeed (2021), leonarditin bitki kuru ağırlığını, bitki boyunu, bitki meyve sayısını arttırdığını bulmuşlardır. Leonarditin bitki gelişimine olumlu etkilerinin olduğu ve bitki besin maddelerinin alımında iyileşmelerin görüldüğü bazı araştırıcılar tarafından ortaya konmuştur (Aguire et al 2009;Ertani et al 2011;Tahiri et al 2015).…”
