Effect of organic manures on growth, yield and quality of turmeric (Curcuma longa L)

Abstract

The use of organic manures in the agricultural plays a vital role in improving the quality of turmeric as well as improving the soil health. Turmeric is having a close relation with human health; hence demand of organically grown turmeric is increasing tremendously. A field trial was conducted to study the effect of different organic manures (generally recommended fertilizer dose, farmyard manure, vermicompost, press mud compost, poultry manure, sugarcane trash, wheat straw, turmeric trash and jeevamrut ) on the yield and curcumin content of turmeric Cv. Phule Swarupa on Inceptisol at Agricultural Research Station, Dist-Sangli, Maharashtra, India. The trial was conducted on the fixed site of soil for the continuous of five years (2009-2013). The maximum dry yield (62.42 q ha-1) of the turmeric was recorded by application of the general recommended dose of fertilizer (GRDF) i. e. 25 MT FYM + 200:100:100 kg N:P2O5:K2O ha-1 which was at par with the vermicompost (11.36 T ha-1). The highest number of leaves per tiller and number of tillers per plant, plant height and curcumin content was recorded in the GRDF, which was at par with vermicompost. The highest benefit: cost ratio (1.59) was also noticed in GRDF, which was at par with the application of vermicompost (1.54) on a nitrogen basis. The soil available nutrient status was taken into consideration during experimentation. The application of vermicompost (11.36 T ha-1) along with Phosphate Solubilizing Bacteria and Azospirillium @ 5 kg ha-1, respectively at the time of planting was found superior for higher dry yield (55.45 q ha-1), net monetary returns (Rs. 137035) and maintenance of soil fertility for organic cultivation of turmeric.

Effect of sugarcane pressmud with inorganic fertilizers on growth and yield of turmeric (Curcuma longa L.

“…The second highest rhizome yield was obtained with RDF + 15 t pressmud ha -1 (32.81 t ha -1 ), while the lowest yield (28.09 t ha -1 ) was produced by the control. The present findings are in agreement with the observations of Kadam and Kamble (2020);Chamroyet al, (2015); Kamal and Yousuf (2012); Balakrishnamurthy (2007) in turmeric.The addition of pressmud improves the soil texture; and makes the soil loose and friable, a condition favourable for the development of underground storage organs such as rhizomes. The manifold improvement of soil properties may have resulted in increasing the availability of both macro and micro nutrients in readily available form.…”

“…The high organic matter content of pressmud improves thesoil conditions for theuptake of nutrients by the increased quantity of plant roots (Kumar et al, 2016). The higher uptake of nutrients from the soil could have resulted in the production of taller plants with more photosynthetic area in the form of longer and broader leaves.Similar results have also been reported by Lohar and Hase (2021); Kadam and Kamble (2020)…”

“…Since, most soils in India are low in organic matter content, turmeric responds well to the application of organic matter. Experimentalevidences are available on the beneficialeffects of organic matter either alone or in combinationwith inorganic fertilizers on growth, productivity andquality of turmeric (Lohar and Hase, 2021;Kadam and Kamble 2020). Since, the traditional sources of organic matter are in short supply, alternateand readily available means of organic matter has to be explored.…”

Integrated nutrient management in turmeric (Curcuma longa L.) cv. GNT-2

“…The highest benefit cost ratio (3.77) and the maximum net realization (6,76,970 Rs./ ha) was obtained under FYM 15 t/ha + 50 % RDF + Novel organic liquid nutrients 5% (T ). This might be due 8 to higher yield and lower investment in this treatment which in turns lead to maximum net profit as compared to other treatments.Similar results were obtained by Kadam and Kamble (2020) in turmeric.…”

Soil fertility assessment of organically grown turmeric in Vasmat tahsil of Hingoli district

“…Consequently, there was reduction in the consumption of organic manures in addition to excess use of inorganic fertilizers to obtain high yields of improved varieties. The continuous and indiscriminate use of high analysis fertilizers has resulted in several problems such as acidity, alkalinity, micro nutrient deficiencies, soil and ground water pollution (Kadam, 2020) [11] . There is a need to maintain proper co-ordination among resources like soil, water, organic matter, biotic life and plant nutrient supply to maintain crop production at higher level (Anal, 2020) [2] .…”
