Abstract
Cannabis producers, especially those with organic operations, lack reliable information on the fertilization requirements for their crops. To determine the optimal organic fertilizer rate for vegetative-stage cannabis (Cannabis sativa L.), five rates that supplied 117, 234, 351, 468, and 585 mg N/L of a liquid organic fertilizer (4.0N–1.3P–1.7K) were applied to container-grown plants with one of two coir-based organic substrates. The trial was conducted in a walk-in growth chamber and the two substrates used were ABcann UNIMIX 1-HP with lower water-holding capacity (WHC) and ABcann UNIMIX 1 with higher WHC. No differences in growth or floral dry weight (yield) were found between the two substrates. Pooled data from both substrates showed that the highest yield was achieved at a rate that supplied 389 mg N/L (interpolated from yield-fertilizer responses) which was 1.8 times higher than that of the lowest fertilizer rate. The concentration of ∆9-tetrahydrocannabinol (THC) in dry floral material was maximized at a rate that supplied 418 mg N/L, and no fertilizer rate effects were observed on Δ9-tetrahydrocannabidiolic acid (THCA) or cannabinol (CBN). The highest yield, cannabinoid content, and plant growth were achieved around an organic fertilizer rate that supplied 389 mg N/L during the vegetative growth stage when using the two coir-based organic substrates.

Производители каннабиса, особенно с органическими операциями, не имеют достоверной информации о требованиях к внесению удобрений для своих культур. Чтобы определить оптимальную скорость органических удобрений для каннабиса вегетативной стадии (Cannabis sativa L.), пять показателей, которые обеспечивали 117, 234, 351, 468 и 585 мг N / L жидкого органического удобрения (4,0 N-1,3P-1,7 K) были применены к растениям, выращенным в контейнерах, с одним из двух органических оснований на основе коры. Испытание проводилось в загрузочной камере для выращивания, и использовались два субстрата: ABcann UNIMIX 1-HP с меньшей водоудерживающей способностью (WHC) и ABcann UNIMIX 1 с более высоким WHC. Между двумя субстратами не было обнаружено различий в росте или цветовом весе (выходе). Объединенные данные с обеих субстратов показали, что максимальный выход был достигнут со скоростью, которая давала 389 мг N / л (интерполированная из ответов на урожайность), которая была в 1,8 раза выше, чем у самой низкой скорости внесения удобрений. Концентрацию Δ9-тетрагидроканнабинола (THC) в сухом цветочном материале максимизировали со скоростью, которая давала 418 мг N / л, и эффекты ΔN-тетрагидроканнабидиоловой кислоты (THCA) или каннабинола (CBN) не наблюдались. Наибольший урожай, содержание каннабиноидов и рост растений были достигнуты на уровне органического удобрения, который обеспечивал 389 мг N / л на стадии вегетативного роста при использовании двух органических субстратов на основе коры.

In the expanding North American medical cannabis industry, growers lack reliable and systematically investigated information on the horticultural management of their crops, especially with regard to nutrient management and growing substrates. To evaluate organic substrates and their optimal nutrient management, five rates that supplied 57, 113, 170, 226, and 283 mg N/L of a liquid organic fertilizer (2.00N-0.87P-3.32K) were applied to container-grown plants [Cannabis sativa L. 'WP:Med (Wappa)'] in two coir-based organic substrates. The trial was conducted in a walk-in growth chamber and the two substrates used were ABcann UNIMIX 2-HP (U2-HP) with lower container capacity (CC) and ABcann UNIMIX 2 (U2) with higher CC. U2-HP produced 11% higher floral dry weight (yield), 13% higher growth index (GI), 20% higher Δ 9-tetrahydrocannabinol (THC) concentration, 57% higher THC yield (per plant), 22% higher D 9-tetrahydrocannabidiolic acid (THCA) yield, and 20% higher cannabigerolic acid (CBGA) yield than U2. Increasing fertilizer rate led to increased growth and yield but also to a dilution of THC, THCA, and CBGA. In U2-HP, to maximize both yield and cannabinoid yield, the optimal organic fertilizer rates were those which supplied 212-261 mg N/L. For U2, the highest applied rate, that supplied 283 mg N/L, maximized yield; although lower rates delivered higher cannabinoid concentrations in dry floral material. The results on these substrates and recommended fertilizer rates can serve as a guide when using other organic fertilizers and substrates; although results may differ with cannabis variety.
