Effect of agri-silvi-horticultural system on growth and yield of wheat

Abstract

An experiment was conducted during 2011-12 and 2012-13 in a 10 years old silvi-horti systems comprising Shisham (Dalbergia sissoo) + Aonla (Embilica officinalis), Shisham (D. sissoo) + Guava (Psidium guajava), Khejri + Aonla and Khejri + Guava planted at a spacing of 6 m x 6 m. Wheat (Triticum aestivum), was raised in interspaces of the silvi-horti systems. Under agri-silvi-horticultural system, no significant effect of woody trees on the germination of wheat crop as well as sole crop during both the years was observed. The yield of grains per hectare of sole crop (4.07 and 4.08 t/ha for 2011-12 and 2012-13, respectively) was significantly higher than agri-silvi-horticulture systems (2.34 -3.01 and 2.53-3.13 t/ha for 2011-12 and 2012-13, respectively). Among the agri-silvi-horticulture system, guava+ khejri exhibited the highest yield (3.01and 3.13 t/ha during both the years).
