Abstract
An agri-horticulture system experiment of mango + rice + wheat crop was carried out at Pikridih village, Raipur in Chhattisgarh for two tears of observations (2017-18 & 2018-19). Mango plantation at spacing of 28 x 28 m and were intercropped with rice and wheat in 2017-18 & 2018-19. The growth performance of (oryza sativa L.) var. ‘Sarana’ and (Triticum aestivum) var. ‘Sarbati’ at different treatments site located between four clumps along with a separate open plot had been studied for the performance of diverse growth and yield attributing characters as well as the grain yield and these were found higher in rice crop grown as sole crop (T4) i.e. crop height (105.2 cm), panicle length (22.9 cm), panicle weight (3.2 gm panicle-1), count of healthy and unhealthy seeds (149.7 and 41.5), number of locules (217.4 panicle-1), seed weight of panicle (3.05 gm panicle-1), test weight (22.9 gm per 1000), grain yield (44.6 q ha-1), straw yield (75.9 q ha-1) and harvest index (37.4%).
Similarly in case of wheat the performance of growth and yield attributing characters as well as the grain yield were also studied where height (95.9 cm.), Panicle length (14.3 cm.), Panicle weight (1.5 gm), count of healthy and unhealthy seeds (32.9 and 2.8), number of locules (41.2 per panicle), seed weight (panicle-1) (1.5 gm panicle-1), test weight (41.5 gm per 1000), grain yield (11 q ha-1), straw yield (8.9 q ha-1) and harvest index (55.1%) were found higher in sole crop grown with significant variations. The performance of eco-physiological parameters (RGR, NAR & LAR) of rice and wheat crops, the plant and soil nutrients reputation with litter fall and decomposition conduct and economics of mango based traditional agri-horticulture system were also studied intensively. The growth parameters and yield of rice and wheat crop was observed significantly highest in open field crop as compare to mango based traditional agri-horticulture system. Mango litter fall and its decomposition showed almost 88.3 percent disappearances within duration of year, indicating ensured nutrients return to the system. The economics of rice-wheat cropping below mango based agri-horticulture system showed meager profit in comparison to mono-cropping however determined economically feasible and technically possible through sharing the inputs of irrigation, manure and fertilizer, weeding and so forth implemented to agriculture crop’s.
The end result of this research showed that highest economic gain of rice and wheat crop rotation was found under mango based agri-horticulture system with both tangible and in tangible benefits.
