Abstract

Nutrient uptake efficiency in sugarcane (Saccharum officinarum L.) must be increased using organic matter to restore soil fertility, resulting in greater productivity. The humic substance is a complex organic material that is excellent for overcoming this challenge. This study aimed to determine the effect of the humic acid enriched by liquid urea by-product (PSUC) and liquid NPK by-product (PSNC) application on the growth and productivity of sugarcane. The experiment was conducted from October 2021 to September 2022 on PT RNI plantation land, Jatitujuh, Majalengka. The research was arranged in a completely randomized (CRD) using two different humic acid product prototypes (PSUC and PSNC) with two evaluation times, a screening and a semi-pilot scale. Solid humic at a dose of 15 Kg ha⁻¹ was applied by mixing it with inorganic fertilizers, while liquid humic at a total dose of 15 L ha⁻¹ was applied by foliar spray technique at 1, 2, and 3 months after planting (MAP). The results showed that applying humic acid PSUC and PSNC enhanced sugarcane shoot growth, segmented stem number, and diameter. In addition, it could consistently promote sugarcane yields on the semi-pilot scale up to 19.18% and 24.26% under humic acid PSUC and PSNC treatments, respectively. Therefore, both in the screening and semi-pilot evaluation, the solid and liquid humic acid PSUC and PSNC applied simultaneously are potential organic materials to enhance sugarcane growth and yield.

Abstract

The effectiveness of humic acid application in increasing shallot yields for farmers must be studied, particularly in terms of quality and quantity. It is also consistent with the relatively high consumption and public demand for shallots year after year. The purpose of this study was to examine how humic acid spraying affects shallot growth and production. Humic acid was applied in two stages: fertilizer coating and foliar spray, with varying treatment dosages. Field testing was conducted in two trials. The initial test revealed that the treatment plants grew faster than the control plants, potentially increasing yields by 7−15%. The validation test (second test) with three treatments yielded the same results: treatment plants outgrew the control specimen, increasing yields by 20−25%. Based on these findings, the use of humic acid may be an alternative for enhancing the agricultural industry, particularly in shallots.
