ABSTRACT
Aims: The combination of various sources of organic manures along with liquid organic manures is important to maintain nutrient availability to crop and sustain higher level of soil fertility. The aim is to meet the nutrient demand of parching sorghum as per requirement at different stages through solid and liquid organic manures which can give greater productivity of crops.Study Design: The experiment was laid in Randomized Complete Block Design with 9 treatments replicated thrice.Place and Duration of Study: A field experiment was conducted at College of Agriculture, Vijayapur, during Rabi, 2020-21.Methodology: The treatments were T1-Ghanajeevamrutha based on 100% RDN (recommended dose of Nitrogen) as basal dose, T2-Vermicompost based on 100% RDN as basal dose, T3- T1 + foliar application of 10% vermiwash at 20 & 45 DAS (days after sowing), T4- T1 + foliar application of 10% cow urine at 20 & 45 DAS, T5- T1 + foliar application of 25% jeevamrutha at 20 & 45 DAS, T6- T2 + foliar application of 10% vermiwash at 20 & 45 DAS, T7- T2 + foliar application of 10% cow urine at 20 & 45 DAS, T8- T2 + foliar application of 25% jeevamrutha at 20 & 45 DAS and T9- Organic RPP of parching sorghum with SMJ-1 variety of parching sorghum.Results: The application of ghanajeevamrutha based on 100 per cent RDN as basal dose + foliar application of 25 per cent jeevamrutha at 20 and 45 days after sowing recorded significantly higher dry matter production (55.86 g plant-1), leaf area index (3.49), raw and roasted grain weight (39.49 g and 51.73 g respectively), raw and roasted grain yield (1063 kg ha-1 and 1505 kg ha-1 respectively) of parching sorghum (hurda) at harvest as compared to other treatments. In addition to improvement in the major plant nutrient uptake were recorded with incorporation of ghanajeevamrutha or vermicompost along with the liquid organic manure.Conclusion: The application of ghanajeevamrutha based on 100 per cent RDN as basal dose coupled with foliar application of 25 per cent jeevamrutha at 20 and 45 days after sowing recorded significantly higher growth, yield, quality and plant nutrient uptake by parching sorghum.
ABSTRACT
Aims: Foliar nutrition is aimed to eliminate the problems of fixation and immobilization of nutrients. Hence, foliar nutrition is being recognized as a significant way of fertilizing modern agriculture, especially under rainfed conditions. Liquid organic manures are the concoctions of micro and macronutrients that also contain vitamins, amino acids, growth-promoting substances, and beneficial microbes. Study Design: The experiment was laid out in a split plot design with three replications. Place and Duration of Study: A field experiment was conducted in medium black soils at Regional Agricultural Research Station, Vijayapur, during Rabi, 2020-21. Methodology: There were fifteen treatment combinations, consisting of five organic sources (vermiwash @ 10%, cowurine @ 10%, jeevamrutha @ 25%, bio digester filtrate @ 25% and urea @ 2%) in main plots and three stage of application (pre flowering, pod initiation and pre flowering + pod initiation) in sub plots for JG-11 variety of chickpea. Results: Foliar application of jeevamrutha @ 25% both at pre flowering and at pod initiation stages recorded significantly greater dry matter accumulation in leaves, stem and reproductive parts, higher SPAD values, number of pods plant-1 (46.5), grain weight plant-1 (9.45 g), harvest index (2198 kg ha-1). Soil dehydrogenase activity, protein content and protein yield parameters also showed higher values for the same treatment along with the major nutrient uptake. A significant reduction in the observation of pest load of chickpeas at pod development stage was noticed by the application of treatment. Conclusion: Foliar application of liquid organic manures, either jeevamrutha @ 25% or cow urine @ 10% both at pre-flowering and at pod initiation stages helped to increase growth, growth attributes like dry matter accumulation, SPAD values, yield attributes, protein content, dehydrogenase activity, major nutrient uptake and reduction of pest load in chickpea.
