“…Weeds are controlled by mechanical, hand weeding, or chemical methods. Although mechanical and hand weeding are effective and environmentally friendly, they are time-consuming and costly [14,15]. Hosseini-Evari et al [16] revealed that a combination of herbicide (Metribuzin) with the mulch method can be useful for weed management in saffron.…”

Saffron (Crocus sativus L.) is among the world’s most expensive crops; nevertheless, it struggles to compete with weeds. Non-chemical farming practices, such as intercropping and reduced irrigation, can help to decrease weed problems. Therefore, this study aimed to evaluate the changes in the weed density, biomass and weed diversity under saffron-chickpea intercropping system with two irrigation regimes. The study’s treatments included two irrigation regimes, namely one-time irrigation and conventional irrigation (carried out four times from October through May), and six planting ratios of saffron and chickpea, namely saffron sole-crop (C1), chickpea sole-crop (C2) in eight rows, 1:1 (C3), 2:2 (C4), 2:1 (C5), and 3:1 (C6)] as main and sub-plots, respectively. The result showed that the conventional irrigation regimes increased weed diversity, however, it didn’t affect the Pielou index. Intercropping ratios decreased weed diversity compared to saffron and chickpea mono-cropping systems. The interaction effect of treatments was significant for weed density and weed biomass. In most intercropping ratios, weed density and weed biomass decreased under one-time irrigation regimes. The lowest values for weed density and biomass were observed with an average of 15.5 plants/m2 and 37.51 g/m2, respectively, under the one-time irrigation regime with C4 intercropping systems. This intercropping system did not show a significant difference with C3. Overall, the results indicate that a one-time irrigation regime and intercropping with chickpea, specifically with a 1:1 saffron-chickpea ratio (C3) and a 2:2 saffron-chickpea ratio (C4), could be effective strategies for weed management in saffron in semiarid cropping systems.

“…Saffron is grown on different types of welldrained soils with a pH range from neutral to slightly alkaline (Ghanbari et al, 2019). According to the results of research (Mzabri et al, 2022), the productivity of the receptacles is affected by illumination: the highest productivity is observed at 30% shading. The culture is resistant to low and high temperatures and withstands their range from -22 to 40°C (Siney et al, 2020).…”

The introduction of new crops to agrophytocenoses, to which Crocus sativus belongs, should be preceded by research into their ecological safety and place in crop rotation. When harvesting raw materials for obtaining saffron, up to 90% of by-products remain, which during decomposition can have a negative effect on the soil and indirectly on the plants that are grown after saffron. Therefore, the aim of the research was to study the allelopathic activity of water-soluble and volatile secretions of Crocus sativus flowers in the agroclimatic conditions of the Northern Black Sea region. The research was conducted in 2021 according to the generally accepted methodology, freshly picked flowers were used, from which individual elements were extracted, and flowers of different stages of flowering. The following research methods were used: field, laboratory, computational and statistical. The results of the research established that the water-soluble secretions of Crocus sativus flowers and their parts stimulate the energy of germination and inhibit the growth of one-day seedlings of Lactuca sativum. Water-soluble secretions of Crocus sativus flowers have a negative allelopathic effect. The index of allelopathic activity under the action of water-soluble secretions of flowers ranges from -0.26 for a flower with all parts to -0.01 for petals. The highest stimulating effect of volatile secretions on the growth of Lactuca sativum roots and the allelopathic activity index value is characteristic of the flower that has just bloomed and the stamens, and the lowest - for the pistils. The allelopathic activity of the volatile secretions of Crocus sativus flower parts is set at the level of 6.4 (pistil) and 28.8% (stamens). Substances that inhibit the germination of Lactuca sativum roots are found mainly in the stamens. It was determined that the volatile secretions of Crocus sativus flower parts reduce the energy of seed germination of the test plant. The practical value of the research is that the results of the research can be used when determining the place of the crop in crop rotation and the duration of its cultivation in one field

There is a need to summarise information using phenological models to develop a sustainable saffron production technology with further regulation of flowering at a certain phenological stage and determination of the appropriate flowering period to improve yield and quality under different environmental conditions. The purpose of the study is to establish the course of phenological phases of saffron growth and development in the conditions of the Right-Bank Forest-Steppe of Ukraine. Phenological observations and biometric measurements were performed in the study. According to field observations, there are a total of 6 phenological stages of saffron development. The rest period lasts from the third ten days of May to October and is divided into primary and secondary dormancy. During the primary dormant period, corms do not show external morphological changes and growth, but internal physiological and morphogenetic changes occur. In the secondary dormant period, the initial emergence of leaves and flowers and their differentiation take place. During the dormant period, saffron plants were left without aboveground organs. The flowering period falls in October. The passage of this phenological stage may be affected by changes in environmental conditions or agricultural technology. The growth of the root system began with the appearance of flowers and leaves. During the growing season, the growth of the leaf apparatus and the development of the root system continue. During this period, daughter corms are also formed from the buds of the mother corm. During the winter, the replacement corms continue to grow using the nutrient reserves of the mother corm. In early March, the development of the root system slows down and the daughter corms reach almost the final size. At the end of the growing season, the root system of the mother corm stops growing. The leaves begin to age from the top to the base. By the end of May, the daughter corms are fully developed and are preparing for the transition to a dormant state. The number of corms produced per unit area depends on the age of the plot, nutrient supply, and the level of agricultural technology. Older fields produce more corms. Due to the higher density, a larger yield of stamens is formed. Therefore, understanding the phenological reactions and influence of climatic factors on the stages of saffron growth and development in certain soil and climatic conditions is useful for future forecasting of harvest time
