Impact of Pruning and Agronomical Management on Wood Production and Yield of Paddy under Dalbergia sissoo Roxb. Based Agroforestry System

Abstract

(M.P.) during, kharif season of 2014. The experiment involve four pruning intensities+one open (without tree) in main plot and Three agronomical management practices in sub plot under strip plot design with five replications. The results revealed that, the growth and yield attributing parameters of paddy were significantly varied due to the effect of different pruning treatments and agronomical management practices. Among all the treatments open condition (crop only) produced significantly higher grain and straw yield (24.8 q ha-1 and 37.7 q ha-1 , respectively). Under agronomical management system 25% more nitrogen produced significantly higher grain and straw yield (21.6 q ha-1 and 36.2 q ha-1). It was found that the diameter at breast height (Dbh) of tree was significantly influenced by different pruning treatments. 25% pruning recorded significantly higher dbh (23.98 cm). The cylindrical volume and stand biomass of tree significantly influenced by different pruning treatments, 25% pruning recorded significantly higher cylindrical volume (217.27 m 3 ha-1) and stand biomass (167301.31 kg ha-1), which was significantly superior to 75% pruning and at pt par with no pruning and 50% pruning. The present study suggested that shade of trees adversely affects growth and yield of crop but silvicultural operation which can reduce tree canopy, facilitated entry of sunlight, pruning is one of them.

Assessment of yield losses in rainfed rice due to weed competition under different pruning intensity of Dalbergia sissoo based Agroforestry system

“…Hand weeding treatment proved its superiority over herbicidal treatments with respect to plant height but in case of yield attributes it found to be at par with Pendimethalin + bispyribac sodium Furthermore, each herbicidal treatment and hand weeding proved superior over weedy plots with respect to growth and yield attributes. Parallel results have been reported by Patel et al, 2017, Kar et al, (2022) [9,7] Yield Different pruning levels and herbicides treatments exert significant effect on yields of rice (Table-2), data presented in Table-2 showed that grain and straw yield of rice significantly increased due to increasing of pruning intensity and the highest grain (35.60kg / ha) and straw (70.40 q / ha) yields were recorded under 75% pruning which was statistically at par to open. The significantly lowest yields of grains (21.90 q/ ha) and straw (60.20 q/ ha) were recorded under without pruning of Dalbergia sissoo.…”

rowth of Betung Bamboo (Dendrocalamus asper) and Food Crop Production Under Agroforestry Bamboo Systems

“…The interaction treatment that produced the highest rice yield was the planting pattern of agroforestry bamboo + rice -2 of the rindang 2 variety + cassava (0.35 kg m ) or 3.475 ton -1 ha . This rice production is higher than the rice yield planted -1 between Dalbergia sisso trees (0.062.4 tons ha ) (S. Patel et al, 2017), rice among mango trees with productivity 2,97 kg -2 12 m (Miyagawa et al, 2017), and rice planted under the sengon (Falcataria mollucana) with a productivity of 2.58 -1 ton ha (Wijayanto & Karimatunnisa, 2022). The rindang 2 variety can produce a higher rice yield in bamboo agroforestry cropping patterns and mixed food crops such as rice, taro, and cassava.…”

Effect of pruning intensity and herbicidal application on soil properties under rice: Dalbergia sissoo based agroforestry system

“…Dalbergia sissoo Roxb., is a deciduous, quickly growing, hardy, medium to large-sized, multipurpose tree, and yields excellent quality timber, highcalorie fuel wood, and crude protein-rich feed (Singh and Sharma, 2007;Jackson, 1987) [19,8] . Because of these advantages, it is commonly recognised as a good agroforestry plant in Central India (Bhargava and Rai, 2019; Patel et al, 2017) [2,17] . Rice (Oryza sativa L.) is the most important staple food for 65% of the population in India and most popular food of the developing world.…”
