Effect of organic, inorganic and integrated nutrient management on yield attributes, production of onion and soil properties, under vertisol of Maharashtra

Abstract

Field experiment was conducted in rabbi season of 2016-17 at Research Farm of at AICRP on Integrated farming System. Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani entited "Effect of Organic, Inorganic and Integrated Nutrient Management on Soil Properties, Production and Economics of Onion Under Vertisol". The experiment was laid out on Vertisols with eight treatment combination, replicated three times in randomized block design. Application 50% recommended NPK +50% N trough FYM/crop residues/compost/other organic source + inorganic sources of micronutrient as per soil test the highest onion bulb yield (139.57 qt ha -1 ) and leaf strew yield (2.02 qt ha -1 ) was recorded by INM treatments. The growth parameters of onion plant height, number of leaves per plant significantly differed over inorganic and absolute control during crop growth period. Similarly, nutrient availability of N (183.56 kg ha -1 ), P (14.23 kg ha -1 ) and K (369.56 kg ha -1 ) was recorded of application of treatment 50% recommended NPK + 50% N trough FYM/crop residues/compost/other organic source + inorganic sources of micronutrient as per soil test than rest of the treatments. The bulk density was improved by application of organic and INM than inorganic and control treatments during the crop growth period. The results in respect of pH, EC and organic carbon showed significant variations among the treatments due to application of organic, inorganic and INM treatment.

Nutrient content, quality and yield of yam bean as affected by different levels of inorganic and organic manure in coastal region of Maharashtra

“…A gradual increase in nitrogen, phosphorous and potassium content of leaves was observed with increasing levels of nitrogen and phosphorous fertilizers in all growth stages of yam bean crop. These results are in close conformity with results reported by Salvi et al, (2014) [30] and Rathod et al, (2018) [26][27][28] who reported significantly highest nitrogen, phosphorous and potassium content due to integration of inorganic fertilizers, poultry manure and Azotobacter. The treatment receiving 120:80:100 N , P 2 O 5 , K 2 O kg ha -1 + 20t FYM ha -1 noted significantly highest levels of nutrients in leaves at all growth stages.…”

“…It was medium in available nitrogen (420.57 kg ha -1 ), very low in available phosphorous (11.74 kg ha -1 ) and high in available potassium (297.38 kg ha -1 ) content in its initial physio-chemical analysis. These Results are in line with the results reported by Shinde et al, (2010) [33] , Salvi et al,(2014) [30] and [26][27][28] . In general, it can be concluded that soil of experimental site indicated typical lateritic soil of Konkan region.…”

“…The higher levels of reducing and non-reducing sugars were observed in treatment receiving highest levels of nitrogen, phosphorus and FYM which was statistically at par with treatments containing FYM @ 15-20 t ha -1 and reduced level of nitrogen and phosphorus (T 8 , T 9 , T 10 , T 11 , T 12 ). Similar findings of increased TSS, reducing sugars and total sugars content of ridge gourd with combined application of inorganic and organic manure have been reported by Rathod et al, (2018) [26][27][28] . The increase in the non-reducing sugars content can be attributed to the fact that nitrogen significantly increases sucrose contents, recoverable sugar yield adding to the highest level of nitrogen and association exists between uptake and accumulation of nutrient in tuber and also between their combined role in enhancing the synthesis of sucrose content and accumulation in tubers (Pushpalatha et al, 2017) [24] .…”

Influence of Integrated Nutrient Management (INM) on Bulb Yield and Profitability of Onion (Allium cepa L.) Crop in Western Uttar Pradesh, India

“…The increased bulb formation, larger-sized onions, and overall improved yield might be since organic manure supplied balanced nutrition to the crop, improved soil condition and thereby resulted in better growth and development leading to higher yield. The above outcomes are correspondingly in nearby conformism by the result of Thangasamy et al [6], Sharma et al [7] Rathod et al [8] and Verma et al [9] in Allium cepa L.…”

Image-based Onion Disease (Purple Blotch) Detection using Deep Convolutional Neural Network

“…Recent research has shown that dietary onions can help prevent heatstroke and other disorders [13]. The onion bulb [14] is abundant in carbohydrates, calcium, and phosphorus.…”
