Investigating the Effect of Intercropping Replacement and Additive Series on Yield, Yield Components and in Camellia and Lentil under Rainfed and Irrigation Conditions
This research was carried out in order to evaluate the effect of intercropping of replacement and addition series on the yield and yield components of Camelina and Lentil under rainfed and irrigated conditions.
The experiment was carried out in the form of split plots in the form of a basic design of randomized complete blocks with three replications in the research farm of the Faculty of Agriculture of Ilam University in growing season in 2020-2021 and 2021-2022. The main plots include irrigation on two levels (rainfed and irrigated) and the subplots include alternative and incremental mixed cropping patterns in nine levels including (75% Camelina+ 25% lentils, 50% Camelina+ 50% lentils, 25% Camelina+ 75% lentils), 100% Camelina+ 25% lentils, 100% Camelina+ 50% lentils, 100% Camelina+ 75% lentils, 100% Camelina+ 100% lentils, monoculture of Camelina and lentils).
The results showed the highest grain yield (1827 kg ha-1) and biological yield of camelina (7012 kg ha-1) in the series of 100% camelina+ 25% lentil and the highest grain and biological yield of lentil was 750 and 1950, respectively, related to monoculture lentil cultivation. The evaluation of the ratio of land equality showed the superiority of all ratios of camellia and lentil intercropping over their monoculture, and the incremental rows of 100% camellina+ 75% lentils and 100% camellina+ 100% lentils had the highest LER.
The results showed that the intercropping of camelina and lentils under irrigation and rainfed conditions was beneficial and superior compared to their monoculture.
