Abstract
The present investigation entitled ―Performance of field crops and eucalyptus clones under agri-silvicultural system‖ was carried out at research area of Forestry Department, CCS Haryana Agricultural University, Hisar during kharif and rabi seasons of 2016-17. The experiment was carried out to study the effect of different eucalyptus clones (C-83, C-7, C-413 and C-288) on the performance of field crops (cowpea and barley) as well as changes in chemical properties of soil. The maximum plant height (9.69 m), basal diameter (12.37 cm) and diameter at breast height (9.52 cm) was recorded in eucalyptus clone C-413. However, the maximum (2.36 m) crown width was attained by C-288 clone. Plant population, plant height, fresh leaves and stem weight, green fodder and dry matter yield of cowpea were found significantly higher under C-83 as compared to other clones under study. The crude protein yield of cowpea was also recorded higher under C-83 (1.02 t/ha) clone while percent crude protein of cowpea was recorded maximum (12.20 %) under C-413 clone. Different growth parameters viz. plant population, number of tillers, number of spikes, number of grains per spike, test weight of barley was of barley also found higher under C-83 clone as compared to other clones. Plant height of barley at different stages of growth was observed significantly higher under the plantation of C-83 and C-288. The grain, straw and biological yield of barley were observed higher under C-83 clone. The soil pH and EC deceased more under plantation of eucalyptus clones over control (sole crop). A considerable increase in soil organic carbon and available N, P and K content was also observed under eucalyptus based agri-silvicultural system than under control (devoid of trees).
