Abstract:
The field experiments were carried out during Rabi seasons of 2020-21 and 2021-22 at Students’ s Instructional Farm (SIF), Chandra Shekhar Azad University of Agriculture & Technology, Kanpur, to study the “Response of nutrient management in Citronella (Cymbopogon winterianus), Lemongrass (Cymbopogon flexuosus) and Palmarosa (Cymbopogon martinii) intercropping with Wheat (Triticum aestivum L.)”. was carried out on a sandy loam soil at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during 2020-2021 and 2021-22. To study the effect of Wheat on growth, yield and biomass yield of Citronella, Lemongrass and Palmarosa and their economics. The experiment was laid out in Split Plot Design with 9 cropping systems with different combinations [Lemongrass + Wheat (100% RDF), Citronella + Wheat (100% RDF), Palmarosa + Wheat (100% RDF), Lemongrass + Wheat (75% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM), Citronella + Wheat (75% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM), Palmarosa + Wheat (75% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM), Lemongrass + Wheat (50% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM), Citronella + Wheat (50% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM) and Palmarosa + Wheat (50% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM)] each replicated 3 times. The soil of experimental field was slightly alkaline with 8.08 pH and 0.21 EC. The soil is low in organic carbon and low in available nitrogen (260 kg/ha), medium in available phosphorous (17.62 kg/ha) and medium in potash (175.5kg/ha). The Citronella crop (cv.BIO-13), Lemongrass (cv.Pragathi-1) and Palmarosa (cv.PRC-1) was planted in 27^th august 2016 at 60X60 cm with different nutrient management as 100% RDF, 75% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM 50% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM. The Wheat (HD-2967) was sown 29^th November 2020-21 and 30^th November 2021-22 at 20cm spacing. The intercrop during Rabi season was sown along with Citronella, Palmarosa and Lemongrass as per treatment to maintain the different Nutrient management with cropping system. The Lemongrass, Citronella and Palmarosa herbs for harvested during experiment period on 24^th Nov 2020, 10^th April 2021 and 25^th Nov 2021, 10^th April 2022 after harvesting of essential oil yielding herbs distillation was done for oil extraction. Highest B:C ratio in was found in Wheat intercrop with Palmarosa (75% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM) is 2.6842 followed by followed by Wheat intercrop with Palmarosa (50% RDF + 5 t/ha FYM + Azotobactor + PSB @ 500 ml in 50 kg FYM) is 2.6220 and lowest in Citronella + Wheat (100% RDF) is 2.1468.
