In Khasi mandarin (Citrus reticulata Blanco) influence of rootstock age (i.e. 05, 06, 07, 08, 09, 11, 12, 13, 14 months) and propagation methods (i.e. wedge grafting and T-budding) on graft/bud success, plant survival, scion physiology and root morphology were studied. The wedge grafting performed on six months old rootstock (T2) recorded maximum graft success (90.0%) and plant survival (88.87%) followed by T3 (80.0 and 77.17%), i.e. wedge grafting on seven months old rootstock, which was significantly (P=0.05) higher than T7 (68.33 and 67.78%), i.e.conventional T-budding on twelve months old rootstock. Morpho-physiological traits, viz. higher individual leaf fresh weight (0.42g) and dry weight (0.16 g), specific leaf weight (5.19 mg/cm2) and leaf thickness (496.67 μm) were recorded in T2. In addition, the leaf pigment contents, viz. chlorophyll ‘a’ (0.77 mg/g tissue) and total chlorophyll content (1.12 mg/g tissue) was found higher in T2 followed by T3 (0.76 mg/g tissue and 1.07 mg/g tissue). Similarly,carotenoid content was recorded maximum in T2 (47.07 μ/g) at par with T-budding on eleven (43.15 μ/g) and 12 (42.94 μ/g) months old rootstock. Relative leaf water content was recorded highest in T3 (61.29%) and T2 (60.68%).Further, T2 recorded higher total root length (385.36 cm) and root surface area (721.20 cm2) while, root volume wasrecorded maximum in wedge grafting on five month old rootstock (156.29 cm3) at par with T3 (155.01cm3) and T2(152.31 cm3). The root diameter was recorded highest in T7 (7.54 mm), whereas the root to shoot ratio was foundhighest in T2 (0.88) followed by T3 (0.75) and T7 (0.70). The results suggested that wedge grafting method could begainfully exploited for Khasi mandarin propagation.
The Northeast region (NER) of India comprises of 8 sister states namely Assam, Meghalaya, Tripura, Nagaland, Sikkim, Arunachal Pradesh, Mizoram and Manipur. The region has an agrarian economy composing of rich agricultural resources which needs strategic exploration for inclusive growth of the region. This can be achieved through the realization of the immense scope and potential for agribusiness in the region. The study aims to explore the agribusiness scenario in the region and to throw light on the constraints in the sector prevailing in the region. Several agribusiness ventures have also been discussed which have potential in the region’s unique business ecosystem. Finally several strategies were provided which may have policy implications on future entrepreneurial development strategies in the region. The descriptive policy paper was formulated based on data collected and experienced gained from over four years (2016-2020) of entrepreneurial development activities by the Agri Business Incubation Centre under Indian Council of Agricultural Research, Research Centre for North Eastern Hill region (ICAR RC for NEH) and its 5 regional centers across the NER. Further, references from other researchers have been included to substantiate the topics discussed here and improve validity of the observations. Agribusiness sector in the region may be promoted through intensified entrepreneurial initiatives by adequately exploiting the resource potential, particularly in agriculture, horticulture, animal husbandry and fishery sector. This creation of market driven products to suffice the demands of growing middle-class consumers will lead to improve rural employment generation, augment farm income and raise revenue through intensified participation in export trade. However several infrastructural, technical and policy improvement have to be made in order to unlock the potential of these ventures. Only planned structural and strategic changes which include increased exports, impactful research and development, institutional support, etc., can be catalytic for entrepreneurial development in the region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
