In an agroforestry practice of land use pattern, the study on integration of curryleaf with tamarind was conducted from 2002 to 2016 on red gravelly degraded soil conditions of Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The ten tamarind clones viz., V-2, TH, H-5, P-11, S-132, U-112, PKM-2, B-1, S-201 and HR-107 were planted at 6 x 6 m spacing and curryleaf of two rows planted at 2 x 2 m apart in the inter space of tamarind alley in three replications in the Randomized Block Design. The curryleaf yield was higher when it is grown in V-2 tamarind clone. Fruit yield of tamarind was higher in V-2 and PKM-2 clones as compared to other clones. Among the agroforestry systems, higher net returns, IRR per cent and B : C ratio were recorded in the V-2 tamarind clone + Curryleaf (Rs. 9,764.5/ha/yr; 64 % and 2.16 respectively) followed by the clone PKM-2 + Curryleaf (Rs. 8,561.8/ha/yr; 51 % and 1.85, respectively) as compared to other clones. The integration of curryleaf at the initial stage of tamarind orchard is more successful practice of establishment of tamarind plantations.Keywords

A field experiment was conducted to know the economically viable trees on degraded lands at MARS, UAS, Dharwad under rainfed conditions. Nine trees viz., Eucalyptus tereticornis, Tectona grandis, Dalbergia sissoo, Anogeissus latifolia, Albizia lebbeck, Grevillea robusta, Hardwickia binnata, Acacia nilitica and Azadirachta indica were planted at 2 x 2m with three replications in Randomized Block Design. Among the tree species, total biomass was higher in Albizia lebbeck followed by Eucalyptus tereticornis and Grevillea robusta. Soil physical properties like bulk density significantly decreased in Dalbergia sissoo, Anogeissus latifolia, Albizia lebbeck and Hardwickia binnata. Trees have reduced pH of soil compared to open conditions. The available nitrogen, phosphorus and potassium were higher in soil grown with tree canopy of Albizia lebbeck, Hardwickia binnata and Tectona grandis, respectively. The gross return, B : C ratio and IRR were higher in Tectona grandis (Rs. 31,647/ha/yr, 4.71 and 22 %, respectively) followed by Eucalyptus tereticornis (Rs. 22,547/ha/yr, 3.52 and 21 %, respectively) as compared to other tree species.Keywords

The study on germination of different sources of Pongamia pinnata was carried out in the nursery of the Department of Farm Forestry at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during the year 2015. The nine Pongamia sources were received from Mahatma Phule Krishi Vidyapeeth (MPKV), Rahuri, Maharashtra for multilocation trial and were evaluated under nursery for vigour and germination percentage. The seeds were measured for its width, bredth, thickness, test weight. Variation in intial parmaters viz., germination per cent, vigour index, ischolar_mains and shoot length were significantly higher among the Pongamia sources of RAK-7, RAK-10 and RAK-2 as compared to other sources tested.Keywords

Different density experiment was conducted to know the effect on growth and productivity of Melia dubia. The trial was laid out with different spacing regimen as per statistical design. The growth observations were recorded at different intervals of time viz., 42, 45, 48 and 51 months after planting. The results revealed significant difference among different planting densities and maximum was recorded in planting density of 714 trees/ha (46.85 cm, 10.59 m; 50.14 cm, 10.99 m; 52.99 cm,11.22 m and 55.76 cm,11.43 m) for both girth (cm) and height (m), respectively for all the time interval. However, the total stand volume (m3/ha) in all the time interval was significantly superior in case of planting density of 2500 trees/ha (125.00 m3/ha, 148.33 m3/ha, 165.83 m3/ha and 189.25 m3/ha). Based on the results of the present experiment it is concluded that, the planting density of 2500 trees/ha exhibited significant stand volume compare to other planting density. These findings have significant relevance to get maximum productivity under monoculture block plantation system.Keywords

An experiment was conducted to know the performance of marihal bamboo (Oxytenanthera stocksii) under Agroforestry system in rainfed conditions during 1999-2006 on red gravelly soils of Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The bamboo was planted in three spacings viz., S1 - 4 × 2m, S2 - 4 × 3m, S3 - 4 × 4m, S4 - 4 × 5m and S5 - Field crop. Sesamum crop was grown for four years. At the end of 2006-07, bamboo culm height and diameter were significantly higher in spacing of 4 × 5 m as compared to 4 × 2 m. Harvestable culms and gross return were higher in wider spacing (4 × 5m) as compared to narrow spacing (4 × 2m). The sesamum grain yields were higher in wider spacing than narrow spacing.Keywords

A field experiment was initiated at Main Agricultural Research Station, UAS, Dharwad from 2011-12 and 2012-13. Glyricidia sepium was grown at 10 m alley and planted at 1 m apart. Four pruning intensities were imposed on Glyricidia sepium alleys. Both groundnut and bengalgram crops were grown sequentially in the inter space of alleys. The groundnut pod yield and grain yield of bengalgram were significantly higher in Glyricidia pruned at 75 per cent of height as compared to the other pruning levels. Pruning of Glyricidia had significantly higher number of branches and total biomass with Glyricidia pruned 75 per cent of height as compared to other treatments. This may be due to higher number of branches and higher number of prunings.Keywords
