TAILIEUCHUNG - Effect on monetary return in various pruning intensities and agronomical management on Dalbergia sissoo biomass production under agrisilviculture system
The experiment was carried out at dusty acre farm, Department of Forestry, College of Agriculture, . Jabalpur during the year 2014- 2015. Manipulation in agronomical practice like higher seed rate, fertilizer dose with different pruning intensities which can compensate the yield reduction to shade under agrisilviculture system. The experiment consists of four pruning intensities viz., no pruning, 25% pruning, 50% pruning and 75% pruning and one open condition (no tree crop only) in main plot and three levels of fertilizer doses and seed rate viz., T1 recommended dose of fertilizer and seed rate, T2 - T1 + 25% more nitrogen than recommended dose of fertilizer and T3- T1 + 25 % more seed rate than recommended dose of seed rate in sub plot replication in 5 times. 75% pruning recorded significantly higher yield attributing characters as compared no pruning. Different pruning treatment showed significant effect on net monetary return. 25% pruning recorded significantly higher monetary return (Rs 2,47, ha -1 ) at par with 50% pruning (Rs ha-1 ) but significantly superior to 75% pruning (Rs 1,25, ha-1 ). Under managed agroforestry system . D. sissoo in 25% pruning recorded higher monetary return (Rs 2,47, ha-1 ) then tree alone (Rs 2,01, ha-1 ) and unmanaged agroforestry system . no pruning (Rs 2,11, ha-1 ). Agronomical management T2 . 25% more nitrogen than recomended dose gave significantly higher monetary return (Rs 2,05, ha-1 ) and compare to recommended dose of nitrogen and seed rate T1 (Rs 1,97,791 ha-1 ) but at par with T3. The maximum biomass percent increased by 25% pruning, no pruning, 50% pruning as compare to 75% pruning. | Effect on monetary return in various pruning intensities and agronomical management on Dalbergia sissoo biomass production under agrisilviculture system
