Kajian Antagonisme Hara K, Ca Dan Mg pada Tanah Inceptisol yang Diaplikasi Pupuk Kandang, Dolomit dan Pupuk KCl terhadap Pertumbuhan Jagung Manis (Zea mays saccharata L.)

Abstract

Antagonism nutrient study for K, Ca and Mg in the Inceptisol soil that applied manure, dolomite and fertilizers KCl to the growth of sweet corn (Zea mays saccharata L.). The purpose of this research is to study the interaction between potassium fertilizer, dolomite and chicken manure on the growth of sweet corn (Zea mays saccharata L.) and assess the antagonism nutrient for K, Ca and Mg in the Inceptisol soil that applied manure, dolomite and fertilizers KCl against growing sweet corn (Zea mays saccharata L.). The result showed the interaction between potassium fertilizer, dolomite and chicken manure on the uptake of calcium, potassium and magnesium in plants sweet corn (Zea mays saccharata L.). There is antagonism nutrient calcium, potassium and magnesium plant sweet corn (Zea mays saccharata L.) on the ground Inceptisol that applied manure, dolomite and fertilizers KCl. The balance of the nutrient uptake of calcium, potassium and magnesium plant achieved at doses of potassium fertilizer at 100 kg K2O / ha

Respons Karakter Agronomi pada Tanaman Jagung (Zea mays) Varietas Pioneer 36 Akibat Aplikasi berbagai Teknik Pengendalian Organisme Pengganggu Tumbuhan

“…Saat fase generatif dan memasuki proses pengisian biji, fotosintat yang tersedia akan dialokasikan untuk digunakan dalam pembentukan biji pada tongkol jagung. Sedangkan, kalium yang terkandung di dalam unsur makro dan mikro alamiah berperan juga dalam pembentukan biji pada tongkol, karena meningkatkan transportasi fotosintat dari daun ke seluruh jaringan tanaman (Putra dan Hanum, 2018). Apabila tanaman mengalami kekahatan kalium, maka dapat menurunkan laju fotosintesis, karena terjadi penumpukan fotosintat pada daun, sehingga memengaruhi pembentukan biji pada tongkol jagung.…”

The Effect of Granular KCl Fertilizer Dosage on K-available, K-uptake, and Yield of Sweet Corn (Zea mays saccharata sturt.) in Inceptisol from Jatinangor

“…Dryland, such as Inceptisols, generally has relatively low nutrient content. Potassium levels in Inceptisols are in the range of 0.1-0.2 cmol kg -1 , which is relatively low [3], even though element K is needed in large enough quantities for plant growth. So that the application of inorganic KCl fertilizers can be a solution to sufficient K nutrient deficiencies.…”

“…So that the application of inorganic KCl fertilizers can be a solution to sufficient K nutrient deficiencies. In addition to soil factors, high rainfall in the tropics causes K nutrients to be easily leached, so much K is lost [3].…”

Tolerance Level of Butterfly Pea (Clitoria ternatea L.) to Stress Acidity Through Tissue Culture Technique

“…(Mulyani and Sarwani 2013). Acidic soils generally has pH characteristics of 4.6 -5.5, as well as fairly high clay content and relatively low potassium levels ranging from 0.1 -0.2 me/100 g of soil (Putra and Hanum, 2018).…”
