Abstract

Three experiments were laid at Forest Divisions, Ludhiana (Baddowal, site-I), Gurdaspur (site-II) and Tarn-Taran (site-III) to estimate the productivity of Bhadrachalam Eucalyptus clones. The data was also collected from different private farms. At Ludhiana, clone 413 gave the maximum MAI (mean annual increment) of 28.80 m³/ha/year, over bark and 23.49 m³/ha/year, under bark, at an age of 3 years. The clone 526 performed better at Gurdaspur with maximum MAI (productivity) of 21.15 m³/ha/year, over bark and 17.25 m³/ha/year, under bark. Whereas, at Amritsar, clone 413 was most productive with MAI of 36.07 m³/ha/year, over bark and 29.42, m³/ha/year, under bark, at the age of 2.5 years. The present study revealed that the clone 413 gave outstanding productivity over bark ranging from 28.80 m3 to 36.07 m³/ha/year. However clones like 526, 2045, 2070, and 285 also performed well. The analysis of data from private farms revealed that clone 288 gave MAI of 48.79 m³/ha/year over bark, followed by clone 316 with MAI to the tune of 33.70 m³/ha/year (Private farm at Hoshiarpur) at the age of 4 and 5 years, respectively. Though other clones under study had less productivity nevertheless their productivity was significantly higher than seed route plants. The clonal Eucalyptus gave 2 to 6 times more volume per hectare as compared to the seed origin plants. However, the growth and productivity of clones 407 (Site-III) and 72 (Site-II and III) was at par to the seed route plants, hence should not be recommended for plantations.

Abstract

The ischolar_maining behaviour is important for selecting clones for multiplication, as hard-toischolar_main clones are likely to increase the cost of production of propagules substantially. In this experiment, ischolar_maining ability of nodal shoot cuttings of 20 clones of Dalbergia sissoo Roxb. were studied under intermittent mist conditions. Out of twenty clones, clone No. 33 (Tulsipur, Gonda), 24 (C.B. Ganj, Bareilley), 10 (Pathri, Haridwar), 237 (Banketwa, Gonda), and 9 (Chiryapur, Bijnor) produced the maximum shoot diameter, dry weight of ischolar_main and shoot, number of ischolar_mains and average ischolar_main length of resultant plants. Propagules of these clones could be produced of plantable size in less than 121 days.

Abstract

One to three years old plantations of Tectona grandis (Teak), Acacia nilotica (Kikar) and Azadirachta indica (Neem) were subjected to seven treatments in the frost affected areas from October 2004 to March 2005. The assessment of percentage damage was made by measuring the height loss in the affected plants. The results indicate that Tectona grandis was the most affected species producing 15.81% damage and the Azadirachta indica the least (4.83%). Among the treatments T₂ (irrigation after 15 days interval during frost period) was found the best giving the least damage percentage (4.08) followed by T³ (application of NPK fertilizer) giving 4.91% damage. The results indicate the traditional measures such as covering of plants with thatching grass (kullies) and polythene bags were not effective. The results also found that in Teak and Kikar, the damage increased from Ist to IIIrd year whereas in Neem, it decreased. The method described in the experiment can be reliably used in the field to assess the damage due to frost. Height / diameter ratio can also be used to gauge the propensity of frost damage and thus to take advance silvicultural operations in time.

Abstract

One, two and three year old plants of Acacia catechu, A. nilotica and A. tortilis were subjected to no pruning (control), ⅓ pruning and ½ pruning of the total height of the plants. Measurements of height and diameter increment per cent were worked out and analysed statistically. The results show that maximum diameter and height increment was found in one year old plants as compared to two and three year old plants in all species. Clear bole formation was significantly higher in 3 year old plants than one and two year plants. ½ and ⅓rd pruning were equally effective in height increment per cent, whereas ½ pruning was highly significant for diameter increment and clear bole formation than ⅓rd pruning and no pruning. The maximum diameter increment per cent and clear bole formation was attained in A. nilotica as compared to A. tortilis and A. catechu. The results suggest no pruning in one year old plants of Acacia catechu, ⅓rd pruning in A. tortilis and ½ pruning in A. nilotica for one and two year old plants.

Abstract

An experiment was conducted in July, 2005 at Kharkan Research Station, Hoshiarpur to find out the effect of irrigation regimes viz., no irrigation (I₀), irrigation after 10 days (I₁₀), irrigation after 20 days (I₂₀) and irrigation after 30 days (I₃₀), and fertilizer (Urea) doses viz., no fertilizer (F₀), 50 g/tree in July (F₁), 25 g two times during July and August (F₂), 16 g three times during July, August and September (F₃), 100 g in July (F₄), 50 g two times during July and august (F₅), 33.3 g three times during July, August and September (F₆), 150 g in July (F₇), 75 g two times during July and August (F₈) and 50 g urea/tree, three times during July, August and September (F₉). Fertilizer dose in the 8 9 second and third year was increased by 50 per cent to the quantity applied during previous year. During first year irrigation regimes had no significant effect on collar girth and height of teak, however, fertilizer dose of 33.3 g Urea/tree, three times in July, August and September, gave maximum collar girth (2.43 cm). The interaction, 33.3 g Urea/tree and no irrigation gave higher collar girth (2.89 cm) and tree height (1.13 m), up to the age one year. Summarized results indicate that irrigation regime I₁₀ for first and second year and I₂₀ during third year were better for growth of teak trees. The fertilizer dose 33.3 g applied three times, during July, August and September, every year resulted in higher diameter and height growth and hence the maximum volume and MAI.

Abstract

Height, diameter growth and volume production of 12 clones of poplar were evaluated at Kharkan Research Station Hoshiarpur, Research Circle Hoshiarpur, Punjab Forest Department at the age of 3 years. The results of evaluation revealed that among the poplar clones under study, the clone WSL - 39 achieved the best growth and maximum volume production, attaining diameter of 14.74 cm; height 14.42 m and volume 0.1040 m³/tree at the age of 3 years. The clone WSL-39 outperformed for growth and volume since the beginning. However, the volume production of clone Udai was at par with WSL - 39 at 2 and 3 years of age. On the basis of present results WSL-39 and Udai clones can be included for plantation to broaden the genetic base and more importantly for productivity enhancement.

Abstract

Dalbergia sissoo (Shisham) is an important tree species for production of quality timber. The genetic diversity of shisham is very low; which has perhaps resulted in increased infestation by diseases and insect-pest attack. The species is eclipsed with one of the most important disease called dieback wilt caused by Fusarium solani f. sp. dalbergiae. The biotic and abiotic factors help in the spreading of diseases in the plantation trials of shisham. In the plantation trial at Hoshiyarpur (Punjab) the dieback wilt causes the tremendous damage to standing trees of shisham. Mortality was found highest (7.65%) for the experimental trials of shisham that includes a total of 49 clones and rametes. The disease was spreading rapidly and affecting the other healthy plantation of the trials. The serious preventive management efforts and mitigation measures are required to protect the shisham trials.
