Agronomic response of kangkung plants typical of Lombok Island with a hydroponic system treated with Trichoderma bionutrients

Abstract The kangkung (Ipomoea aquatica Forsk) is water spinach typical of Lombok Island, Indonesia with a crunchy texture and distinctive taste. It is very easy to be cultivated in the home garden organically in soil media, also to be planted hydroponically and aquaponically. Hydroponic system cultivation is the cultivation of plants by utilizing water without using soil with an emphasis on meeting the nutritional needs of plants. One of the nutrients that has good prospects is the Trichoderma bionutrient which is made from a mixture of bioactivator and biourin. The purpose of this study was to determine the agronomic response of water spinach plants typical of Lombok Island with a hydroponic system treated with Trichoderma bionutrients. The study used an experimental method carried out in a plastic house with a hydroponic system. The study used a completely randomized design with hydroponic nutrition treatment consisting of 6 levels, namely: without bionutrients, with bioactivator bionutrients, with biourin bionutrients, with a mixture of bioactivator and biourin, with AB mix nutrition, with a mixture of Trichoderma bionutrients and Ab mix nutrients. Each treatment was repeated 4 times so that there were 24 experimental units. The results showed that the treatment with a mixture of bionutrients with a mixture of bioactivators and Trichoderma biourin was as good as AB mix nutrition in promoting growth and wet weight of kangkung typical of Lombok Island.

ABSTRACT Cultivation using brackish waters can result in nutritional and metabolic imbalances in several plant species, consequently reducing the production of dry matter (DM) and accumulation of toxic ions (Na+ and/or Cl-) in plants. We evaluated the DM production, and nutrient and inorganic solute (Na+ and Cl-) content in green onion plants (cv. Todo Ano Evergreen - Nebuka) under different levels of nutrient solution salinity in combination with circulation frequencies of this solution. Two experiments were conducted in a hydroponic system, using a completely randomized design, in a 6 × 2 factorial scheme, with five replicates: six levels of nutrient solution salinity (1.5, 3.0, 4.5, 6.0, 7.5, and 9.0 dS m-1) and two solution circulation frequencies (twice and thrice a day). In Experiment I, the evapotranspired depth was replaced using brackish water that was used to prepare each of the salinity levels (used exclusively), whereas in Experiment II, brackish water was used only to prepare each of the salinity levels and public water was used (electrical conductivity [ECw] = 0.12 dS m-1) for replacement in all treatments. The increase in the nutrient solution salinity reduced the production of DM and accumulation of nutrients; the reductions were more pronounced when brackish waters were used exclusively (Experiment I). However, the circulation of solutions thrice a day resulted in the harmful effects of the salinity effect. Replacing the evapotranspirated blade with water supply (Experiment II) mitigated the deleterious effects of salinity. Moreover, three circulations of the nutrient solution daily resulted in lower accumulation of inorganic Na+ and Cl- solutes and increased accumulation of nutrients N, P, K+, Ca2+, Mg2+, and S in the culture.
