Introduction: Triticale (X Triticosecale Wittmack) is a cereal crop that can be cultivated in rotation with rice. The occurrence of early autumn rainfall and lack of sufficient opportunity and time for land preparation are some of the problems of second crop cultivation following rice harvest. By reducing soil tillage, it is possible to increase soil water content, and improve soil structure, and aeration. It was assumed that triticale cultivars under conditions of increasing nitrogen fertilization will respond differently to tillage methods. For this purpose, the experiment was conducted to determin the optimal amount of nitrogen fertilizer application and choosing the appropriate tillage method for growing triticale cropm in rotation with rice.
Materials and Methods: To study the effect of tillage methods and nitrogen fertilizer application rates on morphological traits and biological yield of triticale cv. Pazh, a field experiment was carried out as spilit plot arrangements in randomized complete block design with three replications in the research site of Rice Research Institute of Iran (RRII), Rasht, Iran, in 2021-22 and 2022-23 growing seasons. Experimental factors were tillage methods as main plot at three levels (no-tillage, minimum tillage, and conventional tillage) and nitrogen fertilizer application rates as subplots at five levels (0, 46, 92, 138 and 184 kg N ha-1 from urea source).
Results: Results showed that the shortest days to seedling emergence (8.8 days), highest plant density (246 plant.m−2) and highest fresh forage yield (38.4 ton.ha-1) were obtained in conventional tillage plots. Highest plant density (254 plant.m−2), plant height (154.9 cm), number of tillers (5.1), fresh forage yield (45.2 ton.ha-1) and protein content (17.7 %) were obtained by application of 184 kg N ha-1. The highest dry forage yield (14.7 ton.ha-1) and protein yield (2630.3 kg.ha-1) were obtained through combined treatment of conventional tillage and application of 184 kg N ha-1, which was not significantly different from the combined treatment of the minimum tillage and application of 138 kg N ha-1.
Conclusion: Overall, the results of this experiment showed that using the combined treatment of the minimum tillage and the application of 138 kg N ha-1 improved fresh and dry forage yield of triticale. This finding is very important for providing proportion of the livestock and poultry feed, increasing farmers' income as well as improving sustainability in production by including triticale in as a forage crop rotation in monoculture paddy field.
