| Abstract/Description: | A field experiment was conducted during 2012-15 at Research station of ICAR-Central Tobacco Research Institute,Vedasandur, Tamil Nadu ,to study the effect of intercrop population and fertilizer levels in a chewing tobacco (Nicotiana tabaccum L.) + Annual Moringa (Moringa oleifera L.) intercropping system. Annual moringa was planted as an intercrop in chewing tobacco at 100, 75, and 50% plant population. Different fertilizer levels viz.125, 100 and 75% RDF were applied to chewing tobacco as well as for annual moringa. The experiment was conducted in a strip plot design with 3 replications. The levels of intercrop population in chewing tobacco did not affect the growth and yield of chewing tobacco. The fertility levels 125 and 100% RDF recorded a comparable growth and yield of chewing tobacco. The FGLY recorded with 125 and 100 % RDF was 2.94 and 2.86 t/ha respectively. The TCLY recorded with 125 and 100% RDF was 3.51 and 3.43 t/ha respectively. The chewing quality scores were not altered by different levels of intercrop population or fertility levels. Annual Moringa at 100% population significantly increased the pod yield by 56.3% over the other population levels. The Annual Moringa with yield with respect to 125 and 100% RDF are comparable. The pod yield recorded at 125 and 100% RDF was 3.92 and 3.6 t/ ha respectively. Annual Moringa 100% population recorded higher system productivity (7.15 t/ha), LER (1.06), TEY (4.57 t/ha) and net returns ( Rs. 2,02,700/ha). The RDF 100% is sufficient for increased system productivity, LER, system economics and net returns. The residual soil organicC status varied between 0.44 to 0.48%, soil available P between 9.89-10.9 kg/ha, soil available K between 294 to 318 kg/ha at different levels of intercrop and fertility levels. The RDF at 100% is sufficient for higher lamina NPK uptake and lamina chemistry. Annual Moringa 100% population intercropped with chewing tobacco increased the microbial population and dehydrogenase activity. |
