Abstract
The present investigation entitled “Performance of Turmeric (Curcuma longa rosc.) Under Bamboo (Dendrocalamus strictus (Roxb.) Nees based Agroforestry System in Chhattisgarh” was carried out during session of 2017-18 at the research farm of Department of Forestry, IGKV, Raipur. 492012 Chhattisgarh. The experiment was laid out in Factorial RBD with 2 cropping systems viz; bamboo species (Dendrocalamus strictus) and open field condition and three spacing viz; S1 (50 x50cm), S2 (50 x 30cm) and S3 (40 x 30cm) having four replications. In the study the growth parameters and yield parameters viz; height of turmeric crop, numbers of tillers, leaves numbers, leaves length, and Rhizome length, Rhizome width, root length , number of finger, fresh and oven dry weight of rhizome were measured.
The maximum plant height of turmeric crop (83.67cm), were recorded in open field while numbers of tillers (3.08), numbers of leaves (20.79cm) and size of leaves (210.78cm) were recorded maximum in AFS at 120 DAS. The yield parameters showed higher growth in rhizome width (9.58cm), number of finger (4.88plant-1), length of finger (4.90cm), fresh weight of rhizome (69.30gm/plant) and oven dry weight of rhizome (18.84gm/plant) in open field and rhizome length (4.63cm), root length (14.93cm), in AFS.
The yield of fresh weight turmeric was received 225.79 q ha-1 from open field crop as compare to Agroforestry systems (161.46 q ha-1). The variety Ranga is highest yield 206.71 q ha-1 compare to variety Roma 180.55 q ha-1. The spacing S-1 gave highest yield of 209.44 q ha-1 followed by S3 (194.16 q ha-1) and S2 (177.29 q per ha) respectively with significant variation. In case of interaction cropping system x variety yield was received V1 Ranga is highest in both CS-1 x V1 (245.67 q ha-1) and CS-2 x V1 (167.75) respectively. In interaction of cropping system x spacing highest yield observed was CS-1 x S1 (246.31 q ha-1) in open field and CS-2 x S3 (172.65 q ha-1) in AFS system. Interaction of variety x spacing highest yield is S1 x V1 (221.00 q ha-1) compare to S1 x V2 (197.88 q ha-1) respectively. In interaction of cropping system x variety x spacing highest yield is Cs1 x V1 x S1 (252.8 q ha-1) as compare to Cs2 x V1 x S1 (189.2 q ha-1) respectively.
The bamboo population was 44.92 culm clump-1 thus in July and it increased by 8.17±2.79 new culm with 4.88m diameter of clumps. The average height of culm on harvesting of matured culm was 8.98±1.44 m with 3.87cm diameter at 3rd internodes of culm and it produced 12.39 kg culm-1 biomass with share of culm (7.30±0.79 kg), branches (3.44±0.91 kg) and leaves (1.66±0.31 kg). Thus average 14.1 matured culms per clump can be harvested from bamboo based Agroforestry system to generate more revenue along with yield of turmeric crop.
