EFFECT OF FERTILIZERS ON CURCUMA LONGA L. (TURMERIC) GROWTH UNDER AGRI-SILVI-HORTI SYSTEM IN SODIC SOIL

摘要

Present study was carried on eight-year-old Psidium guajava (guava) trees were planted at 10 x 6 m distance, while twelve-year-old Casuarina equisetifolia (Jhau) trees, planted at 10 x 3 m distance. Turmeric (Narendra Haldi-1) was taken in RBD experimental design with three replications in 12 treatments. The C. equisetifolia maximum tree height (22.31m) was found in tree T_1 (50% NPK + 100% FYM) treatment. Whereas the maximum DBH of C. equisetifolia was found in T_4 (75% NPK+100% FYM) treatment (23.88 cm), canopy width (5.42 m) in T_2 (75% NPK+75% FYM) and canopy length (5.51m) were found in the treatment T_3 (100% NPK+50%FYM) at the beginning of experiment. The turmeric crop maximum yield of fresh weight of rhizome (235.33g) was obtained in T_1, 100% NPK (120:80:80kg/ha) +20t/ha FYM/ha treatment and the maximum dry weight of rhizomes (38.77g) was found in T_1, 100% NPK (120:80:80kg/ha) +20 t/ha FYM/ha treatment.
