“…However, without N, the number of tillers is signi cantly lower. This is in line with Razavipour et al (2018), who reported that Azolla's application resulted in a more signi cant tiller number. According to the authors, high tillering capacity is a desirable rice production trait, given that tiller number per plant is closely related to rice plants' panicles number production.…”

A study was conducted at MARDI Seberang Perai, Penang. This study aims to examine Azolla pinnata on the growth and performance of the MR 297 variety. The experiment consisted of five treatments; PK + Azolla (T1); NP + Azolla (T2); NK + Azolla (T3); NPK-Control (T4), and Azolla only (T5). Each treatment has four replications. The experimental design used was a complete randomized block design (RCBD), and all data collected were analyzed using one-way ANOVA with a statistically significant 0.05% test. For the average soil analysis between the beginning and end, all soil analyses showed decreased soil properties except Total N (%) and organic carbon (%). Treatment has a significant influence on the tiller number, the number of panicles, and the yield per pot. There is a significant influence on treatment on plant height and SPAD value in crop growth performance. There was no significant effect on N and P in plant nutrients. In contrast, there was a significant treatment effect on K. This study showed that Azolla could be used as an alternative fertilizer on rice fields because the soil treated with NK + Azolla shows a comparable result with soil treated with inorganic fertilizer without Azolla on the total yield.

“…An enhancement was observed in the growth and outputs of quinoa cultivars following foliar application with AE or MLE. Azolla filiculoides has been widely used in agriculture for improving plant growth [34][35][36] and motivating plant tolerance to biotic and abiotic stress [38,63,64]. Azolla fixes biological N and minimizes fertilizer leaching [65].…”

Growth, Yield, Quality, and Phytochemical Behavior of Three Cultivars of Quinoa in Response to Moringa and Azolla Extracts under Organic Farming Conditions

Increased demand for quinoa as a functional food has resulted in more quinoa-growing areas and initiatives to increase grain production, particularly in organic agriculture. Quinoa seeds are a superfood with incredible nutritional benefits. They are abundant in secondary metabolites with significant medicinal activity. This report was consequently performed to investigate whether Azolla fliculoides (AE) or moringa leaf extract (MLE) foliar spray can be supplemented as organic extracts to enhance quinoa growth and productivity under organic farming. Three quinoa cultivars, KVL–SRA2 (C1), Chipaya (C2), and Q–37 (C3), were grown organically and subjected to foliar spraying with AE or MLE at a 20% ratio, as well as their combination (AE+MLE). Plant performance of the three cultivars was significantly enhanced by MLE or AE applications as compared with control plants. The highest outputs were obtained by AE+MLE treatment, which significantly increased the seed yield by about 29% as compared with untreated plants. Seed quality exhibited a marked increase in response to AE+MLE that was superior in this regard as it showed higher protein, carbohydrates, saponine, tannins, phenolics, and flavonoids content. The C3-cultivar demonstrated the highest productivity, saponine, and flavonoids levels as compared to the other cultivars. Overall, the current study indicated that foliar spray with AE+MLE could enhance growth and productivity as well as quality and pharmaceutical active ingredients of quinoa cultivars grown under farming conditions.

“…Findings by Malyan et al (2019) showed that the use of Azolla reduces the need for application of urea fertilizer by 25% in rice production with no effects on yields. According to Razavipour et al (2018), Azolla use increases tillers, grain weight, yield of rice and is a desirable management practice in rice production Field studies at Ahero Irrigation Research Station in Kenya (1980) confirmed the positive benefit of 4.8 tons ha -1 Azolla when used with inorganic nitrogen (AIR Report, 57). However, the need for extra fields for mass multiplication of Azolla proved uneconomical.…”

Azolla tissue contains 5% N, which is slowly released into the soil upon decomposition. Timing of incorporation is therefore important for maximum benefit to a crop. The effect of time to incorporate Azolla biomass on growth and yield of rice was investigated in Mwea-Kenya. Treatments consisted of 7.5 t ha-1 Azolla biomass applied at transplanting, 7.5 t ha-1 Azolla applied at 21 days after transplanting (DAT) and 30 kg N ha-1 inorganic N applied in splits at O, 21 and at 55 DAT. There were control treatments without Azolla and without inorganic N application. The treatments were laid out in a Randomized Complete Block Design (RCBD) with three replications. Phosphorus and potassium were applied at 50 Kg ha-1 each as P 2 O 5 and K 2 O. Plant height and tiller numbers were recorded at 21 (rooting/tillering), 32 (tillering), 42 (maximum tillering), 60 (flowering) and 75 DAT (heading) while yield parameters were determined at physiological maturity (120 DAT). Data were analysed using SAS software and means separated using the least significant difference test (p≤0.05). Azolla incorporation at transplanting significantly enhanced panicle m-2 , grain weight and grain yield while incorporating it at 21 DAT only significantly enhanced panicle m-2. Higher environmental temperatures enhanced Azolla effect. The effect of Inorganic N significantly increased plant height, tiller number, grain weight and spikelets panicle-1. However, percentage grain filling was reduced. The effect of interaction between Azolla application and inorganic N was significant on spikelets panicle-1 and grain weight. Observations therefore indicate that the effect of Azolla on yield and yield components was more when incorporated at transplanting.
