Pengaruh Pupuk N, P, K dan Pupuk Nano Silika Terhadap N-total, Serapan N dan Hasil Padi Hitam (Oryza sativa L. indica) pada Inceptisols

Abstract

The Inceptisols have the potential to be developed into rice cultivation land because it is widely distributed in Indonesia but it has a low of soil fertility. Fertilization of N, P, K and Nano Silica fertilizers are efforts to provide nutrients for rice plants. Black rice that functional cultivated is Bangir Lokal Cianjur Variety. This study aims to determine the effect of N, P, K and Nano Silica fertilizes on total N content, N uptake, and Black Rice Yield (Oryza sativa L. indica) on Inceptisols. This research was conducted in November 2020 until March 2021 at the Soil Chemistry and Plant Nutrition Experimental Field, Faculty of Agriculture, Universitas Padjadjaran. Jatinangor with altitude 723 m asl. The experimental design was carried out using a RBD consisting of eight treatments and four replications. The treatments consisted of control ( without fertilizers); 1 N, P, K (Urea 300 kg/ha, SP-36 50kg/ha, and KCl 50 kg/ha);1 N, P ,K + 1 Nano Silica (2 mL/L); 1 N, P, K + 1,5 Nano Silica (3 mL/L); 1 N, P ,K + 2 Nano Silica (4 mL/L); ¾ N, P, K (Urea 225 kg/ha, SP-36 37,5kg/ha, and KCl 37,5 kg/ha) + 1 Nano Silica; ¾ N, P, K + 1,5 Nano Silica; ¾ N, P, K + 2 Nano Silca. The result showed that the combination of fertilizers doses of 1 N, P, K and 1 Nano Silica gives the best black rice yield with Dry Grain weight of 77,8 g/clump of rice

Functional food biofortification in increasing red and black rice production through the use of nano silica organic fertilizer

“…Based on the overall cultivar test results, the interaction between the dose of nano silica organic fertilizer and the cultivar had a real to authentic influence on all observed characters. This is also to the results of previous research by Hayati et al (2021), Sabatini et al (2021), andYuniarti et al (2021). Interaction between doses of organic fertilizer nano silica 1000 kg ha -1 and 'Inpago 7' (d2v4) was the interaction between the two most dominant treatments that gave the best results in almost all observed parameters.…”

The use of Silica fertilizer to increase the effectiveness of N,P,K fertilizer on rice plant growth

“…In accordance with the statement [9], available nitrogen affects plant height, number of tillers, leaf width, and number of grains. In addition, according to [10] the addition of silica fertilizer can increase the stability of the root membrane so as to prevent root damage due to water stress in rice plants which can cause reduced nutrient uptake by plants and affect plant growth. The supply of Si also helps the leaves become more upright under the influence of high nitrogen fertilization conditions, so that it can increase the photosynthesis rate up to 10 percent higher than rice plants that are not given silica [11].…”
