ABSTRACT
Field experiments were conducted at Agricultural College Farm, Bapatla during Kharif and Rabi seasons of 2017-2018 and 2018-2019 to study the Phosphorus dynamics in relation to nutrient management in rice- blackgram cropping sequence with respect to changes in soil nutrient status. Results of two years (2017-2019) experimentation revealed that at all growth stages of rice, significantly highest available nitrogen, phosphorus and potassium in soil were recorded with application of RDNK+Dhaincha @ 10t ha-1 (M3) and this was on par with RDNK+ Sunhemp @ 10t ha-1(M2), whereas lowest was recorded in RDNK (M0) alone in both seasons of study. Among the P levels the available nutrient status (N, P and K) were increased with the increasing level of P from 0 (P1) to 120 kg P2O5 (P5) ha-1, irrespective of the nutrients imposed to rice crop. Significantly highest was recorded in P5 (120 kg P2O5 ha-1) and this was on par with P4 (90 kg P2O5 ha-1), whereas the lowest was recorded in treatment P1 that received 0 kg P2O5 ha-1.
ABSTRACT
The objective of the experiment was to examine the effects of organic manures and natural farming on the quality and economics of carrots. It was conducted at the research farm of the Deen Dayal Upadhyaya Centre of Excellence for Organic Farming of CCS Haryana Agricultural University, Hisar, during the rabi season. Three replications and eight treatments were included in the RBD design of the experiment. Three different organic manures were applied: FYM, vermicompost, poultry manure and in combination with biofertilizer (Azatobacter and PSB). Treatment of cow based bio-formulations (Ghanajeevamrit and Jeevamrit) and control was also included as treatment where no biofertilizer and manure were used. The study revealed significant improvements in almost all quality attributes due to the combined application of organic manures along with biofertilizer. Among different treatments, vermicompost + biofertilizer surpassed all other treatments by giving maximum root yield (283.4 qha-1), maximum content of the total sugar (8.79%), reducing sugar (4.09%), non-reducing sugar (4.64%), TSS (11.5°Brix) and Chlorophyll content in leaves (4.37 nmol cm-2). Also, the treatment vermicompost + biofertilizer gave maximum gross return (Rs. 425100 ha-1), net return (Rs. 232873 ha-1), and Benefit Cost ratio (2.21). It was also observed during the study that control treatment showed lowest findings among all the treatments.
ABSTRACT

ABSTRACT
Field experiments were conducted at the South farm in Karunya Institute of Technology and Sciences, Division of Agronomy, Coimbatore, during the Rabi season of 2022. The experimental site is situated in the western agro-climatic zone of Tamil Nadu, at a latitude of 10°56'N and longitude of 76°44'E, with an elevation of 474 meters above mean sea level. The soil composition of the experimental field was identified as clay loam, moderately drained, and exhibited low availability of nitrogen (202 kg/ha), high availability of phosphorus (12.3 kg/ha), medium availability of potassium (415 kg/ha), and organic carbon content of 0.51%. The experiment followed a randomized block design (RBD) with 10 treatment groups, each replicated three times viz.,T1 - Control, T2 - Vermicompost 100% (on N Equivalent basis)+ Cowdung slurry, T3 -Vermicompost100% (on N Equivalent basis)+TNAU Biomineralizer,T4 -Vermicompost100% (on N Equivalent basis) + (Effective microorganism),T5 - Vermicompost 100% (on N Equivalent basis) + Pleurotus sp + Urea, T6- Vermicompost (50%) +RDF (50%) + Cowdung slurry, T7- Vermicompost (50%) +RDF (50%) + TNAU Biomineralizer, T8 -Vermicompost (50%) + RDF (50%) + EM (Effective Microorganism),T9 -Vermicompost (50%) + RDF (50%) + Pleurotus sp ,T10 - RDF alone. The objective of the study was to investigate the impact of vermicompost and other foliar applications on the growth, physiological characteristics, and yield parameters of an irrigated Black gram (VBN8 variety). The promotion of yield can be attributed to the increased vegetative growth and the balanced carbon-to-nitrogen (C: N) ratio, which likely stimulated the synthesis of carbohydrates. This, in turn, facilitated the overall improvement in seed yield. The application of RDF played a significant role in enhancing growth, leading to various positive changes in yield-related characteristics. Ultimately, the increased seed yield observed can be largely attributed to the improved plant growth and subsequent positive effects on yield-related attributes resulting from the RDF application. Thus, From this Experiment it was Concluded that the RDF (T10) Shows a highest range in growth, physiological and yield parameters of irrigated Blackgram due.
ABSTRACT
A field experiment was conducted during the rabi season of 2022 in the farm of Karunya Institute of Technology and Sciences, Coimbatore to study the effect on organic nutrient management on yield and economic returns of baby corn which was grown in silty clay loam soil. Among all the treatment 12.5 t FYM + groundnut cake equivalent to 60 kg fertilizer N provided much better outcomes in terms of yield attributing character and cob yield followed by vermi-compost equivalent to N in 12.5 t FYM + groundnut cake equivalent to 60 Kg fertilizer N. B:C ratio was found higher in 60-30-30 kg NPK through fertilizer alone.
ABSTRACT
A field experiment entitled, Influence of different organic sources of nutrients on yield and quality of pomegranate (Punica granatum L.) cv. Bhagwa. The current study was designed in RBD with three replications consisting of twenty-two treatments with four different organic manures viz., farmyard manure, vermicompost, poultry manure and neem cake as a source of nitrogen and recommended dose of manure and fertilizers based on plant age with or without biofertilizers (Azotobacter, PSB & KMB) and biopesticides (Trichoderma viride and and Paecilomyces lilacinus). The findings based on pooled data discovered that maximum number of fruits per plant (59.50), yield per plant (12.41 kg), yield per hectare (19.86 tonne), fruit weight (239.39 g), fruit diameter (7.55 cm), aril weight per fruit (147.70 g), juice content per fruit (97.55 ml), peel weight per fruit (91.69 g) along with peel: aril ratio (0.62) was significantly noted under treatment 100 % RDN through poultry manure + 50 ml PSB + 25 ml KMB + 5 g Trichoderma viride + 5 ml Paecilomyces lilacinus. The maximum net return (4,12,840/ha) and BCR (3.26) were also obtained in same treatment. Significantly maximum TSS (16.15°Brix), reducing sugar (14.44 %), non-reducing (2.04 %) and total sugar (16.48 %) along with minimum titrable acidity (0.41 %) were recorded with application of 37.5 % RDN through FYM + 37.5 % RDN through neem cake + 50 ml Azotobacter culture + 50 ml PSB + 25 ml KMB + 5 g Trichoderma viride + 5 ml Paecilomyces lilacinus treatment. Whereas, maximum ascorbic acid content (16.72 mg/100 ml juice) was significantly found under treatment 100 % RDN through FYM + 50 ml PSB + 25 ml KMB + 5 g Trichoderma viride + 5 ml Paecilomyces lilacinus.
ABSTRACT
Coleus forskohlii L. is an important medicinal plant species found in tropical regions of India. Roots and tubers are used for treating a variety of purposes, including treating asthma, bronchitis, insomnia, epilepsy and angina.Due to diverse use, the species has been largely exploited from natural habitat leading to its threatened status. A field experiment was conducted to study the influence of organic and inorganic fertilizers on its growth and yield. Six treatments including T1 Control -No Manures; T2: 100% NPK recommended dose (N- 40 kg ha-1), T3: 50% NPK + 10 Tonnes of Farm Yard Manure / ha-1, T4: 50% NPK + 5 Tonnes of Vermicompost/ ha, T5:20 Tonnes of Farm Yard Manure / ha and T6: Vermicompost 10 Tonnes/ha-1. Results indicated the improvement in the growth and yield. Combination of organic and inorganic fertilizers is very productive than the application of manures or fertilizers alone for achieving higher growth and yield in C.forskohli.
