| dc.description.abstract | Integration of trees with fodder crops under agroforestry systems in the humid and sub humid region is a strategy for year-round fodder production and insurance against fodder scarcity. During 2019-2021, a field trial entitled “Growth, Yield and Quality Assessment of Trees and Fodder Crops under Agroforestry System in Ranchi District of Jharkhand” was conducted using the fodder tree Melia azedarach (Bakain) along with the four fodder crops viz., Para grass, Hybrid Napier, Stylo and Charabadam at the research field of Agroforestry situated at the College of Veterinary Science and Animal Husbandry campus, Birsa Agricultural University, Ranchi, Jharkhand. The experiment was laid out in Randomized Block Design (RBD) involving nine treatment combinations replicated thrice. The treatments comprised of Bakain + Stylo, Bakain + Charabadam, Bakain + Para grass, Bakain + Hybrid Napier, sole Bakain, sole Stylo, sole Charabadam, sole Para grass and sole Hybrid Napier. Growth parameters of tree species (Bakain) i.e., diameter at breast height (cm), tree height (m), tree volume (m3/tree), crown diameter (m), number of branches (per tree), number of leaves (per branch), leaf area index; yield attributes of the tree species (Bakain) i.e., green leaf biomass (t/ha), dry leaf biomass (t/ha), fresh weight of the standing trees, dry weight of the standing trees as well as quality attributes of the tree (Bakain) and fodder crops i.e., crude protein content (CP%), crude fibre content (CF%), neutral detergent fibre (NDF%), acid detergent fibre (ADF%), ash content (AC%), ether extract (EE%) and nitrogen-free extract (NFE%), were recorded during both years of experimentation. The growth attributes of fodder crops i.e., plant population, number of branches, number of leaves per tillers and leaf area index; yield attributes of fodder crops i.e., green fodder yield (t/ha), dry fodder yield (t/ha), leaf weight (t/ha), stem weight (t/ha), leaf: stem ratio were observed. Rainfall use efficiency, palatability trial, carbon sequestration potential and economic analysis of the system were also taken into consideration. Results reflect that Bakain intercropped with Stylo recorded better growth with regard to tree height (10.46 m), DBH (17.59 cm), crown diameter (6.28 m), LAI (3.07), number of branches (571.33), fresh biomass (111.69 t/ha) and dry biomass (80.98 t/ha) produced, tree volume (0.253 m3), as well as leaf fodder quality in terms of CP content (12.89%), ADF (37.37%), AC (3.04%) and EE (4.80%), however, sole Bakain contains more CF (53.96%) and NDF (35.21%). Among different intercrops, Stylo recorded more tillers (295.83), crude protein content (15.74%), yield of crude protein (12.16 q/ha), rainwater productivity (0.28 q/ha/mm), carbon sequestration (140.31 t/ha), carbon credit (514.96), gross return (₹.1,86,705 /ha), net return (Rs.1,34,632 /ha) and LER (2.56). However, Hybrid Napier as sole or intercropped recorded highest LAI (4.08), GFY (869.23 q/ha), DFY (149.55 q/ha), NDF (60.62%), ADF (48.24%), CF (62.38%) and EE (5.69%) along with the highest Benefit: Cost Ratio (4.67). Improvement in soil chemical properties was better under intercrops than sole tree or grasses. Among the intercrops, Charabadam intercropped with Bakain has been found to put forth a better impact on soil improvement. The study concludes that the Bakain + Stylo based agroforestry system is viable in degraded or waste land with medium to low fertility for round-the-year production of quality fodder as well as climatic amelioration. This will certainly help improve fodder scarcity for the livestock and uplift the livelihood conditions of farmers in the plateau region of Jharkhand. | |
