Effect of interaction between organic fertilizer and biofertilizer EM-1 on the growth and yield of Linum usitatissimum L.

Abstract

This experiment was conducted to study the effect of interaction between organic fertilizer and biofertilizer EM-1 on the growth and yield of plant. Randomized complete block design (RCBD) was used as a factorial experiment with three replicates at 5% probability level. Organic fertilizer (cow manure) was added to the soil at three levels (0, 2 t/ha^-1, 4 t/ha^-1), symbolized by H0, H1 and H2 respectively, while biofertilizer EM^-1 was used at two levels (0 and 20 L/ha^-1). The results showed that the interaction treatment 4 t/ha^-1 + 20 L/ha^-1 (H1B2) had a significant effect on most of the vegetative growth indicators and yield components represented by plant height (cm), number of fruiting branches. plant^-1, number of capsules. plant^-1, weight of thousand seeds (g), number of capsules. Plant^-1, total seed yield (kg/ha^-1) compared to the interaction treatment without adding (H0B0), this matter is of great importance to find an alternative fertilizer to chemical fertilizers because of its important advantages for human health in particular and its friendliness to the environment in general.
