An investigation was carried out to study the effect of nitrogen and phosphorus on growth, flowering and yield of cut chrysanthemum cv. Thai Chen Queen. The experiment was laid out in randomized block design (RBD) with factorial concept comprising of twelve treatment combinations with four levels of nitrogen, viz., 100 kg N/ha (N1), 150 kg N/ha (N2), 200 kg N/ha (N3) and 250 kg N/ha (N4) and three levels of phosphorus, viz., 50 kg P2O5/ha (P1), 75 kg P2O5/ha (P2) and 100 kg P2O5/ha (P3). The treatments were replicated four times. The results indicated that application of 200 kg N/ha (N3) to cut chrysanthemum was most effective to increase plant height whereas, plants receiving 150 kg N/ha significantly improved vegetative growth as well as quality and yield of flowers. Application of 75 kg P2O5/ha was found promising for growth, quality as well as yield parameters.
Field experiments were carried out in pigeonpea during Kharif 2014 to Kharif 2017 for Maruca vitrata Fabricius management through farmscaping approach with 7 different border crops (5 leguminous crops; 2 non-leguminous crops) and a sole crop. The M. vitrata larval webbing per plant was lowest and per cent decrease in webbing/plant over sole crop was highest in sorghum (2.05 and 60.95) as border crop followed by pearl millet (3.29 and 37.39). The highest mean number of Coccinella septumpunctata per plant (0.77), Cheilomenes sexmaculata per plant (0.85/plant) and spiders (0.76/plant) was recorded from sorghum as border crop with pigeonpea. The highest percent increase in above said natural enemies over sole crop was also recorded from sorghum as border crop treatment (755.6, 844.4 and 660). The highest pigeonpea yield (730.72 kg/ha) and per cent yield gain (65.81%) was also recorded with sorghum treatment. Among 5 weather parameters tested, day length (1.53) and relative humidity (-0.12) were found to influence the M. vitrata population significantly and its incidence was recorded from 41st SMW to 47th SMW.
Floriculture has been associated with culture and heritage since very ancient time in our country. According to Tata Energy Research Institute (TERI), the waste generation rate in India is increasing at the rate of 1.0 -1.33 per cent annually. In most of the developing countries like India, the floral waste generation occurs largely during worships, festivals, ceremonies etc. from temples, mosque, flower market, flower exhibition and wedding halls find their way into the garbage as a waste causing various environmental problems. This paper discusses the use of solid state fermentation to convert floral wastes into a variety of value-added products like as compost, biogas, bioethanol, dyes, food products, biosurfactants production, incense sticks and handmade paper production etc. and floral waste can thus be converted into wealth.
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.
