A field experiment was conducted on already established silvi-horticultural system of agro-forestry at CCS . Regional Research Station, Bawal (Rewari) during the Rabi seasons of 2011-12 and 2012-13, in which, Dalbergia sissoo and Prosopis cineraria were taken as forest tree species and Psidium guajava and Embilica officinalis as horticulture trees planted at 6×6 m distance. Winter crops (wheat, barley and oat) were taken in association with perennial woody plants forming agri-silvi-horticultural system of agroforestry. Seeds of wheat cv. WH- 711, barley cv. BH-393 and oat cv. HJ-8 were sown in line in interspaces. Among the agri-silvi-horticulture system, guava + kehjri exhibited the highest yield. Maximum light intensity was received by crop as well as agri-silvihorticulture system during noon to and highest being in control followed by guava + khejri. Similarly the total light intensity was found maximum in control ( lux) and guava + khejri system (, , and ) during December, January, February and March, respectively. Same trend was observed for incident solar radiation and maximum ISR was observed under guava + khejri during all the months. The grain yield of wheat, barley and fodder yield was found significantly higher under control (sole crop) and among the various agri-silvi-horticulture system, guava + khejri system resulted into higher yield . , and q/ha, respectively. Likewise the straw yield was found maximum in control and highest among the agri-silivi-horticulture system of guava + khejri . and q/ha in wheat and barley, respectively. Total incident radiation was found positively correlated with grain, straw and fodder yield of wheat, barley and oat during all the month of growth, respectively. | Effect of sunlight on different agri-silvi-horticulture combination under agroforestry system
