“…A one-year field-level evaluation in Indiana, USA to optimize the N application with three grain genotypes and two sowing dates with a difference of 13 days was carried out [78]. Nitrogen application of 224 kg N ha −1 increased foliar nitrogen, leaf mass per area (LMA), CBD, and THC as compared to a foliar N application of 168 kg ha −1 .…”

Hemp (Cannabis sativa L. ssp. sativa) has a long history of domestication due to its versatile use. Recently, different sectors in the economy are investigating hemp cultivation to increase agronomic production and to limit delta-9-tetrahydrocannabinol (THC). Despite the rapid growth of hemp literature in recent years, it is still uncertain whether the knowledge gained from higher latitude regions is applicable to low latitude and tropical regions where hemp has not been grown traditionally. This review provides a comprehensive and updated survey of hemp agronomy, focusing on environmental and management factors influencing the growth and yield of hemp, methods of cannabinoids detection and quantification, and hemp breeding. This review suggests that some previous claims about hemp as a low input crop may not hold true in low-latitude regions. Additional research strategies, such as the integration of experimentation and modeling efforts, are encouraged to hasten new discoveries. Furthermore, to effectively increase the outputs of value products (cannabinoids, seeds, fiber and biomass, etc.) while limiting the THC level, new collaborations between hemp agronomists and economists may streamline the production process by increasing the efficiency of the total production system of hemp as a multifaceted crop.

The investigations were carried out at the Experimental Station of Vytautas Magnus University Agriculture Academy, in 2021. The soil of the experimental site is silty light loam Planosol. The aim of the study was to determine the impact of multi-cropping intensity on the prevalence and damage of diseases and pests, as well as on weed abundance and biomass. The methods of crop diversification were studied: 1. Maize mono-crop (KU);2. Hemp mono-crop (KA);3. Faba bean mono-crop (PU);4. Maize and hemp binary-crop (KU + KA);5. Maize and faba bean binary-crop (KU + PU);6. Hemp and faba bean binary-crop (KA + PU);7. Maize, hemp and faba bean ternary-crop (KU + KA + PU). Contrary to expectations, the number of pests found in the hemp mono-crop (KA) and faba bean mono-crop (PU) was lower and the damage caused was lower than in the binary and ternary crops. Crop diversification has been an effective method of controlling faba bean diseases. The lowest abundance and intensity of Botrytis fabae and Ascochyta fabae were found in hemp and faba bean binary-crop (KA + PU). Binary maize and faba bean crop (KU + PU) were most effective in weed controlling, with the lowest number and biomass of weeds.
