Gladiolus is one of the most potential bulbous cut flower crops cultivated widely in India due to its attractive and long lasting spikes. The plant is propagated vegetatively through corms and cormels, but due to low rate of multiplication, its cultivation is hindered. Also, it is grown through underground modified stems, they are more often attacked by soil borne diseases such as Fusarium corm rot. In-vitro propagation techniques, assumes significance, especially for securing rapid multiplication of quality planting propagules using dormant cormlet explants and media. The results of the study revealed that the MS growing medium supplemented with 2 mg/l BAP showed improved results in respect of sprouting of explants (54.46 %), days required for sprouting of explants (8.68 DAI) and shoot length at 30 (6.32 cm), 60 (12.40 cm) and 90 (13.21 cm) DAI. The in vitro regenerated gladiolus plantlets when placed in the rooting MS medium supplemented with 4 mg/l IBA showed earlier root initiation (8.31 DAI) and higher number of roots/shoot (5.37 DAI) as compared to the rest of the treatment combinations. Hardening medium consisting of garden soil + sand + vermicompost (1:1:1) showed greater survivability (50.98 %) of plantlets. Thus, the study has been initiated an efficient protocol for in-vitro propagation of gladiolus through cormlets cultured in MS media containing BAP and IBA as shooting and rooting plant growth regulators and subsequent acclimatization in garden soil + sand+ vermicompost medium.
Precision farming is a science base modern technology which provided management concept based on observation and response to intra-field variations. New technologies such as Global Positioning Systems (GPS), sensors, satellites or aerial images and Geographical Information Systems (GIS) are utilized to assess and analyse variations in agricultural and horticultural production. In this technology have two primary goals that are (i) optimum return (ii) preserving resource. Wireless Sensor Networks has crucial role to management of water resources, to assess the optimum point of harvesting, to estimate fertilizer requirements and to predict crop performance more accurately, disease and pest hazard also. Sensors use to precision farming technology in horticulture, which increasing productivity, decreasing production costs and minimizing the environmental impact of farming. Though precision farming has vital role in Agriculture and Horticulture sector but, no so popular due to high cost of technology and need high speed internet facility.
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.
