Abstract

Climate change and forests are intrinsically linked. On the one hand, changes in global climate are already stressing forests through higher mean annual temperatures, altered precipitation patterns and more frequent and extreme weather events. At the same time, forests and the wood they produce, trap and store CO₂, play a major role in mitigating climate change. During the course of this study, potential of carbon sequestration, one of the major intangible benefits, was studied for 14 Populus deltoides clones. The carbon content was determined in different parts of trees i.e., bole, bark and branches. The results showed that the carbon content was found in the order: bole>branches>bark. Clone 'WIMCO-22' was found the best in terms of carbon stock while WIMCO-42' was the poorest one in this respect.

Abstract

In agroforestry practices generally tree has more pronounced effect on crop growth and yield with increase in its canopy cover. But in the present investigations results indicated that there was no significant (P<0.05) effect of trees on crop. The survival, growth, biomass production and leaf nutrient content of Paulownia were significantly higher as compared with poplar under the agroforestry situation. Similarly, nitrogen (3.02 %) and protein (18.8 %) contents in tree leaves were also highest with the Paulownia clone-GP. Although, the size of the leaves and canopy of Paulownia is larger than the poplars even then influence on yield and yield attributing characters was lesser as the highest yield was recorded under Paulownia only. It is evident from the results that Paulownia and Poplar clones do not have any significant effect on almost all the growth and yield parameters of wheat and maize crops grown in association with trees. The grain yield for wheat crop has a very little difference but maize does not have the difference under the different clones. It indicates the best compatibility of the crops with Paulownia and poplar. it is inferred that over all Paulownia clone-GP out performed all the clones of Paulownia fortunei and Populus deltoides. Thus, the tree has great potential under agroforestry situations in similar agro-climatic conditions of India.

Abstract

An investigation was carried out in the winter seasons of years 1996, 1997 and 1999 to study the atmospheric humidity and air temperature during the active growth stages of wheat (Triticum aestivum L.) crop raised under 8m × 8cm, 6m × 4m, 5m × 5m and 4m × 6m spacings of poplar (Populus deltoides Marsh.) trees. Height, dbh, crown width and crown length of the trees were significantly higher in tree spaced at 8m × 3m when compared with other spacing. Tree spacing significantly influenced atmospheric humidity and air temperature in wheat crop grown underneath poplar. Atmospheric humidity was directly proportional to within row spacing of trees while air temperature showed the inverse relation. Variation among wheat varieties were significant for both microclimatic parameters throughout the cropping period except for atmospheric humidity during jointing stage (11.00 hours) of crop growth. Interaction effects of tree spacing and crop varieties could not influence significantly both these parameters during the entire growth period of wheat crop.

Abstract

Study based on seven Eucalyptus camaldulensis, fifteen E. tereticornis, two urograndis clones, and one seedling population each of E. tereticornis and E.grandisreyealedinterandintra species variation in gall induction and other traits caused by an insect wasp Leptocybe invasa gen. & sp. N. Urograndis clones recorded minimum gall induction whereas, clones belonging to E.tereticornis recorded maximum infestation. Similarly, seedling population of E. grandis was less susceptible to attack in comparison to seedling population of E. tereticornis. Among clones, Urograndis clone BCM-2135 has shown minimum infection (4%) compared to cent per cent infection in a few E. tereticornis clones viz., W-36, W-104 and W-B 10. The other clones of E. tereticornis BCM-10 and W-B 33 showed 84 and80% gall infection respectively. Screening of 24 years old fifteen candidate plus trees of E. tereticornis assembled at R&D Complex of Wimco Seedlings at Rudrapur have also shown varying degree of gall formation. A preliminary survey of gall induction on eucalypts in Punjab, Haryana, Western Utter Pradesh and Plain areas of Uttrakhand indicates spreading infestation of the insect in almost all the locations.

Abstract

Results of a survey conducted during the harvesting of block plantations to diagnose the intercrops grown in poplar based agroforestry (PBAF) are presented here. Informations were collected from 220 sampled plantations from 172 villages, 69 tehsils, 28 districts in 4 states viz, Punjab, Haryana, Uttar Pradesh and Uttrakhand. Wheat was found as main crop grown in 51.67% cases followed by sugarcane, fodder(shorghum/berseem)), maize, jawar/bajra, paddy, dhencha (green manure) and others. The intensity of cropping was more in winter (rabi) season than in summer (kharif) season. Farmers stopped growing intercrops much earlier in summer season than in winter season. Survey further identified intercrops grown in different locations from first year to harvesting age. Validation of the results with the information collected on intercrops in PBAF through field staff of Wimco Ltd was largely in consonance with the findings of the survey. The survey also estimated planting of 24.34 million poplar saplings throughout the region of intensive poplar culture (RIPC) during 2009-10 planting season, out of which 58.38% were in compact blocks and 41.62% were as boundary plantations.

Abstract

The field experiment was conducted during the year 2001 to 2006 on marginal degraded bouldery riverbed lands of Doon Valley in North-West India under rainfed conditions. The performance of grasses viz Panicum maximum (fodder grass) and Eulaliopsis binata (industrial grass for fibre and paper pulp) was evaluated alone and in association with Paulownia fortunei with regard to growth parameters and biomass yield. Seventy five per cent lower portion of the tree crown was lopped every year in the month of October - November to obtain different forms of usable biomass (leaf fodder + fuel wood). The maximum height before lopping of the Paulownia tree was recorded 7.6 m with 17.7 cm Diameter at Breast Height (DBH) in the silvipastoral system, which produced 41.9, 55.6 and 97.5 q

Abstract

Weed control program has considerably enhanced the growth of Populus deltoides G3 at the nursery stage. Though T₄ (manual weeding), was the best method to control weed, but it is labour intensive and costly. T₂ - (Glyphosate-4 application), at the rate of 5 ml diluted in 1 litre of water was also found equally good; thus it is recommended where there is labour scarcity.

Abstract

In two experiments on conditioning of chir pine (Pinus roxburghii Sargent) laid out to raise seedlings for monsoon and winter plantings, seven month old seedlings were subjected to three undercutting depths (7 cm, 12 cm and 17 cm) followed by three wrenching regimes (control, weekly and biweekly) and combination of lateral and box pruning (control, lateral pruning at 6 cm and box pruning at 6 cm from seedlings) and three irrigation intensities (irrigation just after fortnight wrenching, 12 hours after fortnight wrenching and 18 hours after fortnight wrenching). The experiments were laid out in split-split plot design with two replications. Treated plants on providing a rest period of four weeks after final wrenching were outplanted in field at 1.5 m × 1.5 m spacing. Different treatment combinations exhibited varying responses on survival of the outplanted seedlings, recorded after one year. Wrenching frequency significantly improved survival of seedlings. Maximum and highly significant survival was recorded in seedlings wrenched weekly followed by those wrenched fortnightly. Undercutting depth also significantly influenced outplanting survival. Maximum survival was recorded for seedlings undercut at 12 cm followed by those undercut at 17 cm. The results of treatments-lateral pruning, box pruning and irrigation showed non-significant effects on field survival rates.

Abstract

Multiplication of Indian Chir pine (Pinus roxburghii Sargent) cuttings was studies in the nursery beds 5 percent IBA-talc with 10 percent sucrose, 5 percent capaf and 25 peccent perhydroxybenzoic acid (phenol) resulted in 57.13 percent ischolar_maining and 91 67 percent callusing of non-ischolar_mained cuttings compared to 7.14 percent ischolar_maining and 35.35 percent callusing in control. IBA at low concentrations (one percent) induced higher ischolar_maining when side shoots of seedlings were gridled at base and auxin powder formulation rubbed at gridled and finally covered with black tape. Cuttings planted around earthen backed water filled pots have further improved ischolar_maining both quantitatively and qualitatively. Many cuttings developed a strong main ront similar to tap ischolar_main in seedlings.

Abstract

Poplar plantations and nurseries mainly grown on farm land in North India create thick patches of green cover which attract wild animals, birds and rodents for hideout, shelter and food. Many of the visiting wildlife also cause serious damage to poplar both in field plantations and nurseries. The main wild animals and birds causing damage have been identified as blue bull, monkeys, rats, rabbits, crows, parrots etc. The major damage by these agents is caused during dry spell when they get attracted towards the greenery of poplar and agricultural crops grown therewith. The nature and extent of damage and the control measures being applied by the growers are discussed in the paper.

Abstract

A study was conducted for 3 years (1998-2000) on the farmers’ fields in Doon Valley to evaluate the allelopathic effects of trees on the understory crops in a Paulownia and poplar based agroforestry system. Results revealed that leaf leachates of both tree species significantly affected germination of maize and wheat up to 21% and this negative effect was more with 2.0% concentration of leaf leachates in comparison to control. Further it was noticed that this effect was more pronounced with Poplar than Paulownia due to more tannin, wax, flavonoides and phenolics present in the leaf leachates of Poplar. Higher germination and growth parameters of wheat and maize were recorded with 1 and 2 per cent aqueous leaf extract of Paulownia - GP leaves. The Paulownia clone-GP out performed among all the clones of the two species without any significant negative effect on growth and yield attributes of maize and wheat which indicates its compatibility with crops. Thus, it is inferred that the Paulownia clone-GP has great potential as an agroforestry tree species in India under the similar Edapho-climatic conditions.

Abstract

Paper presents morphological characterization of 64 half-sib progeny seedlings raised from seed collected from a single female Populus suaveolens Fisch. tree growing in the vicinity of P. ciliata and two saplings one each of P. ciliata and P. suaveolens raised from stem cuttings. K-Means clustering of leaf and branch morphological traits of progeny seedlings resulted in forming two clusters each of them represented with a sapling each of P. ciliata and P. suaveolens. The 95.45% individual seedlings (62 in number) were clustered with P. suaveolens (female parent) and 4.55% (2 in number) with P. ciliata (male parent). Some traits like, number of glands at the base of leaf blade, pubescence on the lower surface of leaf blade and leaf tip in progeny seedlings were associated with male parent- P. ciliata and two progeny seedlings with these traits got clustered with this species, whereas, the remaining progeny seedlings had leaf and stem traits similar to female parent- P. suaveolens.

Abstract

The study deals with screening of better progenies of different clones of Populus deltoides on the basis of growth viz. diameter at breast height (DBH) and tree height for the development of new better productive clones ANOVA showed that progenies were significantly different for DBH, whereas non-significantly different for tree height. Significant variations in DBH due to progenies indicated that these progenies were different for DBH and this trait was under genetic control. Variations due to replication were non-significant for DBH and tree height. The range for DBH was 18.4 (B-1, female) - 30.57 cm (L-12, male) with a mean 22.6 ± 2.60 cm and for height was 23.06 (B-1, female) - 31 m (L-12, male) with a mean 5.53 ± 1.39 m. On the basis of cluster analysis considering tree height and DBH, progenies 107, 86-1, 35, L-14, L-12 and 183 showed better growth than of the other progenies. The progenies 173, L-12 and 183 were divergent and may be used in hybridization programs. In the study, genetic advance was higher for growth traits and genetic gain for the growth traits was also positive which shows the great possibility of improvement in the species for growth.
