Abstract

Clonal propagation is one of the most effective tools for improvement in forestry. The study describes the scope and development of clonal propagation technology for Bixa orellana commonly known as Annatto. Developing rapid and improved clonal study reveals that clonal prorogation is possible through stem cuttings collected from matured trees. The study standardized the effect of cutting size, concentration of IBA and ischolar_main media on success and survival of stem cuttings in this species. Percentage ischolar_maining and primary ischolar_main number differed significantly between treated and untreated cuttings. Treatment of cuttings with 4000 ppm IBA maximized ischolar_maining (83.30%), along with increased survival (78.30%) and primary ischolar_main number (20.20). Rooting success and ischolar_main number were better in 15 cm x 20 mm diameter sized cuttings. Cuttings planted in sand: soil (1:1) ischolar_mained better with more ischolar_mains ensuring better survival. Survival and growth of the clonal plants were best when using improved techniques like size of the cuttings with proper concentration of IBA and also combined with suitable ischolar_maining media. However, there was significant variation in height growth (shoots sprouts length) of cuttings due to IBA treatments. The results suggested that it could be possible to produce clones of high yielding superior genotypes of Bixa orellana on large scale through stem cutting for popularization and establishment of commercial forestry and agroforestry plantations.

Abstract

The present study evaluated bamboo (Dendrocalamus strictus) based resource conservation in the Yamuna ravines at Central Soil and Water Conservation Research and Training Institute, Research Centre, Agra, Uttar Pradesh, India. Ravine lands are highly degraded dry lands and 3.97 m ha area is affected by ravines in India. One ravine micro watershed of 2.8 ha area was planted with two rows of bamboo in staggered manner as vegetative barrier for the analysis of hydrological and economic aspect of bamboo plantation. Hydrological results showed that runoff has been reduced from 9.6% to 1.8% and soil loss from 4.2 to 0.6 t/ha/year in the last 4 years. Based on bamboo growth performance, average value of culm height and culm collar diameter have been recorded as 3.80 m and 22.50 mm, the value of average crown size and number of culms per clump being 3.93 m and 18 numbers respectively. Further, the soils under bamboo plants improved in terms of decreased pH and enhanced soil organic carbon. The economic analysis suggested a cash outflow of Rs 48,000 ha^-1 from 7th year onwards to the stakeholders in the region, in addition to the benefits accrued to society at large in terms of value of nutrient (Rs 2125-5555 ha^-1) saved through soil conservation. This study recommends bamboo plantation for productive and protective utilization of such degraded lands. It also suggests that the high cost of establishment for individual stakeholders can be met through subsidies and banks' financial inclusion programme in developing countries such as India. Further, public funding can also be routed through appropriate budgetary provisions in development plans of corporate entities involved in the rural development in the country.
