Abstract

A total of 66 villages were surveyed from six types of degraded land areas in arid and semi-arid parts of Rajasthan and Gujarat. Availahility of common access resources (CARs) i.e. Gaucher/Oran and Community wasteland varied from 4% in Johrheed (Bikaner) to 93% in Ramgarh (Jaisalmer) of Rajasthan. Arahle farming and animal husbandry are the main occupation in the area with very high cattle population. 62-100% household fall under the category of marginal land holding (<5 acres) and are totally dependent upon CARs for getting fuel , fodder and even food. The average fuelwood and fodder requirement per household in the area were worked out to be 3.46 tonnes and 2.07 tonnes per year , respectively. To meet this requirement on sustainable basis , productivity of the available CARs need to be maintained at 4.2 tonnes ha^-1 yr^-1. Female members of the family and children mainly carry out collection of fuel and fodder for which they devote 30 to 40 % of their time.

Abstract

Air layering trials were conducted in Neem (Azadirachta indica A. Juss) during the months of February, May and August in areas of Uttaranchal and Punjab. One year old lateral branches were girdled, and IBA 500-1000 ppm was applied at the exposed surfaces and wrapped with moistened sphagnum moss. Callus was formed at the girdled portions of all the air layers, with/or without IBA treatments. Adventitious ischolar_maining was obtained in the air layers of February and May while the layers made during August failed to form ischolar_mains. Even the slight delay in air layering trials during monsoon period may suppress air layering response in Neem. The results of our study suggests that early summer season (May) seems to be best period for air layering in Neem and ischolar_maining was obtained within two months following girdling.

Abstract

Six multipurpose, nitrogen fixing tree species viz., Acacia nilotica. An evergreen, dry zone and Robinia pseudo-acacia, deciduous. Temperate, both spiny medium sized tree species. Albizia lebbek, Dalbergia sisoo fairly large and Ougeinia oojeinensis middle sized deciduous tree of sub-tropical climate upto 1200 m. sub-Himalayan tract and Pongamia pinnata, evergreen, medium sized. Tree widely distributed throughout the country. These species have been used for the various afforestation programmes in the country. The seedlings of these species were raised in Plant Physiology Branch, Botany Division,Forest Research Institute, Dehra Dun, to study the seasonal variation effects on nodulation behaviour and nitrogenase (acetylene-ethylene reduction) activity. In three species viz., Acacia, Ougeinia, Robinia, maximum nitrogenase activity was observed during summer season, whereas, in other three species i.e. Albizia, Dalbergia, Pongamia during rainy season. However, lowest activity in most of the species was recorded during winter season. Maximum nodule number per plant was reported during rainy season except Robinia in summer. An identical trend in nodule growth and nitrogen fixation activity was recorded in Dalbergia and Ougeinia seedlings. Whereas, Acacia, Albuizia and Pongamia have followed almost similar trend among themselves for nodule number and nodule biomass. This study concludes that the nodulation and nitrogen fixation behaviour differs within and between species and seasons.

Abstract

The chances of nitrogenous fertilizer use in various afforestation programmes are very bleak in the near future. The only alternative is to select such species which can meet their nitrogen requirements from soil as well as atmosphere. An attempt has been made in the present study to identify some of the nitrogen fixing herb, shrub and tree species from inner and outer Himalaya region, so that these species can be recommended for the afforestation programmes to a particular area. Out of ninety five species recorded, most of them belong to family leguminosae except Alnus nepalensis and Myrica esculenta non-leguminous.

Abstract

An experiment was undertaken to study the effect of seedlings size on the growth of transplanted spruce seedlings in the nursery. Studies made include observations on survival and growth of seedlings under five different classes based on their hieghts viz. less than 7.5 cm; 7.5 cm to < 12.5 cm; 12.5 cm to < 17.5 cm; 17.5 cm to 22.5 cm and more than 22.5 cm. The performance of the seedlings below 7.5 cm in height in terms of both survival and growth was the poorest as compared to all other classes followed by the seedlings of 7.5 cm -< 12.5 cm height classes which also resulted in lower survival and poorer growth rate than those of the remaining three classes. Seedlings below 12.5 cm in height should, therefore, be culled at the time of transplanting.

Abstract

In an extensive survey to Garhwal Himalaya and arid soil of western Rajasthan. twenty four leguminous nitrogen fixing species were identified including seven herbs, nine shrubs, four climbers and four trees species which were screened for nodulation and nitrogen fixation activity between 400-2100m altitudes. Maximum and minimum nodulation and nitrogen fixation (21881.3 n molesn moles acetylene reduced pl^-1 h^-1) activity was recorded in Desmodium floribundum at 2000m and Atylosia scarabaeoides (56.4 n moles) at 900m altitude respectively. In desert ecosystem, five herbs, two shrubs and three climbers were tested for rhizophoric soil acid and alkaline phosphate and dehydrogenase activity. Minimum and maximum acid phosphatase activity was recorded in Rhynchosia minima and Indigofera argentea and alkaline phosphatase in Indigofera linnaei Ali, and Indigofera sessiliflora. Whereas, minimum and maximum dehydrogenase activity was observed in Alysicarpus longifolius and Indigofera sessiliflora respectively. The identified herb, shrub and climber species may be useful for conservation of degraded site under harsh climatic conditions in temperate Himalayan and Rajasthan desert ecosystem.

Abstract

An experiment was conducted to observe the soil enzyme activity and nitrogen assimilation by five legume species viz: Mucuna pruriens, Clitoria ternatea. Rhynchosia minima (all climbers), Crotalaria burhia and Mimosa hamata (both bushes). Higher soil organic carbon, per gram nitrate reductase and dehydrogenase activity was observed in the bush C. burhia rhizosphere as compared to control. However, maximum moisture content and NO -N was observed in the soil 3 under M. hamata bush than the control. In case of NH -N and phosphorus, higher content was recorded in the soils 4 under R. minima and C. ternatea climbers than the control soil. Maximum and minimum height was recorded in M. pruriens and M. hamata. Whereas, higher acid and alkaline phosphatase activity was recorded from the rhizospheric soil of R. minimaand M. hamata. Maximumcollar diameter and soil electrical conductivity was observed in C. ternatea and M. pruriens soils. M. hamata proved to be well suited in alkaline soil than other species. On the basis of results obtained all these five species influenced higher enzyme activities in natural habitat as well as in the field trial and showedsignificant improvement in soil fertility as well.

Abstract

Seedlings of Myrica esculenta were grown and assessed for its nodulation and nitrogen fixation behaviour at monthly intervals under two different environmental conditions. No nodule formation was observed in two years old seedlings at two different places i) lower altitude i.e. New Forest (FRI), Dehradun ii) higher altitude i.e. Field Research Station, FRI, Khirsu (Pauri), Uttarakhand, even though an aqueous solution of crushed freshly collected nodules and rhizospheric soil from its naturally grown area was applied under each pot of growing plants. Maximum nodule biomass was recorded in summer followed by rainy and least in winter season. Highest nodule numbers were recorded  in rainy season followed by summer and minimum in winter. Seasonally higher g^-1 fr wt h^-1 and pl^-1 h^-1 nitrogen fixation activity was recorded in rainy season followed by winter and minimum in summer season.

Abstract

Rhizobia were isolated from active nodules of Albizia lebbek and Dalbergia sissoo from different sources and confirmed against nodulation test. Several other physiological and biochemical tests were also performed. They were then multiplied in Yeast Extract Mannitol (YEM) broth and inoculated into their respective A. lebbek and D. sissoo seedlings. These were maintained under pot culture conditions in the glass house for few months to study the effect of inoculation treatments on nodulation, nitrogen fixation and biomass production. It was found that A. lebbek seedlings inoculated with rhizobial isolates of Lalpani gave the highest nodular biomass, specific and total nitrogenase activity. In case of D. sissoo, isolate from Asharori resulted in highest nitrogenase activity under pure culture conditions and maximum nodular number, nodular biomass, collar diameter and plant height as compared to other inoculation treatments. No relationship between nitrogenase activities of rhizobial isolates under pure culture and symbiotic conditions was observed. It may be concluded that both the isolates of Lalpani and that of Asharori may be utilized for the forestry programmes of planting A. lebbek and D. sissoo respectively.
