Abstract

Maize production and quality are affected by infection with plant pathogens. One of the maize's essential and main diseases is downy mildew caused by Peronosclerospora spp. Downy mildew is a limiting factor in increasing production and can reduce production by 80-100%. It is because the affected plant cannot produce cobs. Pathogens obtain nutrients from the host cell, which can kill the cell and damage the surrounding tissues, resulting in visible downy mildew symptoms. Boron (B) plays a role in forming phloem, increasing the fruit's number, weight, bunch weight, and diameter. The primary function of B at the molecular level is the cross-linking of pectin in the plant cell wall. Ramnogalacturonan II (RG II) is a pectic polysaccharide that contributes to the mechanical strength and properties of the primary wall cross-linked by borate diesters. Phosphorus (P) controls the downsides in the greenhouse and field conditions. This study aims to measure changes in chlorophyll index, P and B uptakes in downy mildew affected plants. The field experiment used a group randomized design with six natural phosphate (FA) application treatments and four groups of borax doses as replicates. The results showed that the downy mildew decreased the chlorophyll index of the leaves at different levels of attack. The results of P concentration according to the position of healthy plant leaves were significantly different due to P treatment. In contrast to concentration B, there is no real difference. P and B uptake results in downy mildew-infested plants showed a significant difference only in P uptake in leaves with 1 FA treatment. Keywords: boron, downy mildew, maize, phosphate

Abstract

Salah satu upaya pemanfaatan potensi pasir kuarsa yaitu melalui pembuatan pupuk Kalium Silikat (K2SiO3), melalui reaksi SiO2 dalam pasir kuarsa dengan kalium hidroksida (KOH). Penelitian ini bertujuan mendapatkan suhu optimal dalam pembuatan pupuk K2SiO3 melalui pencampuran pasir kuarsa dari Bangka dengan KOH. Lebih jauh penelitian ini bertujuan mengevaluasi kelarutan pupuk K2SiO3 pada tanah serta pengaruhnya terhadap pH tanah, alumunium dapat ditukar (Al-dd), kalium dapat ditukar (K-dd) dan silika (Si) tersedia melalui percobaan inkubasi pada Ultisol Dramaga. Hasil menunjukan bahwa kandungan kalium dalam bentuk kalium oksida (K2O) tertinggi pada perlakuan suhu 1000 oC sebesar 66.9%, sedangkan terendah pada suhu 700 oC sebesar 55.1%. Sebaliknya, kandungan Si dalam bentuk SiO2 pada suhu 1000 oC sangat rendah. Kandungan SiO2 pupuk Kalium Silikat tertinggi pada suhu 800oC sebesar 35.1%. Pupuk K2SiO3 yang paling optimal dari penelitian ini adalah pada suhu 800 oC dengan memiliki kandungan K2O 60.0% dan SiO2 35.1%. Percobaan inkubasi menunjukkan dosis pupuk Kalium Silikat 2.50% adalah dosis yang paling efektif karena selain meningkatkan hara K-dd dan Si tersedia, juga mampu menurunkan nilai Al-dd dan memperbaiki nilai pH tanah menjadi relatif netral.
