Organic Formulations

Background: Development of fortified organic formulations using various organic sources and fertilizers for soil application will ensure efficient nutrient management in homestead vegetable production systems. Fortified organic formulations will help in preventing nutrient leaching also. Hence, the present study has been undertaken during 2019-20 to develop low cost fortified organic manure discs using various biodegradable agro waste materials and NPK fertilizers and to study its effect on growth and yield of tomato in sandy soils of Kerala. Methods: A fortified manure disc was developed by combining local biodegradable agro waste materials with conventional NPK fertilizers. Organic manures like rice husk ash, cow dung, rice husk, coirpith compost, vermicompost, neem cake and clay were used to develop the manure disc. The combination of organic manures was fortified with fertilizers at various proportions of manure: fertilizer viz., 1:1, 2:1, 0.5:1 and manure alone and used for incubation for a period of two months to study the nutrient release pattern of N, P and K.The 2:1(manure: fertilizer) formulation was selected based on the highest peak of nutrient availability of N, P and K even after 2 months. Effect of fortified manure disc was evaluated by using tomato variety Anagha as test crop in a pot culture experiment. Result: Growth, yield and quality of tomato increased significantly due to the application of fortified manure disc. The highest yield per plant of 0.97 kg was recorded for T8 (50% recommended dose fortified manure disc in 2 splits) and lowest yield was recorded for T9 (Manure alone). The fortified manure disc had a significant influence on nutrient use efficiency also. The highest NUE of 45.5% was recorded in treatment T8 (50% fertilizer fortified discs in 2 splits). Study revealed that fortified manure disc is a promising technology to reduce nutrient leaching and enhancing the nutrient use efficiency in sandy soils. Fifty percentage reduction in the recommended dose of NPK fertilizers were achieved by fortifying the manure disc with fertilizers.Thus the cost of fertilizers and fertilizer load per unit area can be reduced by the application of fortified manure disc which will act as slow release fertilizer.

Aims: Investigated the influence of organic manures (municipal solid waste compost [MSWC] and cow dung) and N-fertilizer on growth, yield and nutrient use efficiency of jute mallow (Corchorus olitorius L.) under two water regimes (rain-fed and irrigated). Study Design: Randomized complete block. Place and Duration of Study: Farm of Faculty of Agricultural Sciences, University of Parakou, Northern Benin (latitude 09°20’16.8’’N and longitude 002°38’54’’ E, 353 m asl), during 2013 rainy (June to August) and dry seasons (October to December 2013). Methodology: Ten treatments derived from a factorial combination of five levels of organic manures (control, MSWC at 10 t/ha, MSWC at 20 t/ha, cow dung at 10 t/ha and cow dung at 20 t/ha) and two levels of N-fertilizer (0 kg and 50 kg urea/ha), arranged in a randomized complete block with three replicates were considered. Results: Results showed that water regime significantly (p<.001) affected growth and yield of jute mallow. In addition, the growth and yield parameters showed significant differences (p<.001) in relation to different rates of organic manures.  The integrated use of organic manure and urea increased plant height, number of leaves, stem diameter, number of branches, leaf growth parameters and leaf yield. The maximum amount of leaf yield (7554.88 kg/ha) was obtained with 20 tons/ha of MSWC and 50 kg urea/ha. Conclusion: Fertilizer types also had highly significant effects on nutrient use efficiency. Application of these treatments could help to enhance yield and growth of the jute mallow.

Controlled Release Fertilizers

Owing to the high demand for fertilizer formulations that will exhaust the possibilities of nutrient use efficiency (NUE), regulate fertilizer consumption, and lessen agrophysicochemical properties and environmental adverse effects instigated by conventional nutrient supply to crops, this review recapitulates controlled release fertilizers (CRFs) as a cutting-edge and safe way to supply crops’ nutrients over the conventional ways. Essentially, CRFs entail fertilizer particles intercalated within excipients aiming at reducing the frequency of fertilizer application thereby abating potential adverse effects linked with conventional fertilizer use. Application of nanotechnology and materials engineering in agriculture particularly in the design of CRFs, the distinctions and classification of CRFs, and the economical, agronomical, and environmental aspects of CRFs has been revised putting into account the development and synthesis of CRFs, laboratory CRFs syntheses and testing, and both linear and sigmoid release features of CRF formulations. Methodical account on the mechanism of nutrient release centring on the empirical and mechanistic approaches of predicting nutrient release is given in view of selected mathematical models. Compositions and laboratory preparations of CRFs basing on in situ and graft polymerization are provided alongside the physical methods used in CRFs encapsulation, with an emphasis on the natural polymers, modified clays, and superabsorbent nanocomposite excipients.

Manure Slurry

A good understanding of nutrient release from manure or compost after application through mineralization is important to assure meeting the nutrient demand of crops, to secure timely fertilizer application and to enhance nutrient use efficiency. The current study was done to evaluate phosphorus (P) and sulphur (S) release patterns from different types of manures viz. cow dung, cow dung slurry, tricho-compost, vermicompost, poultry manure, poultry manure slurry and mungbean residues. The mineralization study was performed under aerobic (field capacity) and anaerobic (waterlogging) conditions for 180 days at 25 ± 1 °C in the laboratory. The release of P and S showed the highest values within 75–180 and 75–150 days, respectively, and was always higher in aerobic conditions than in anaerobic conditions. The first-order kinetic cumulative model was a good fit for mineralization, which was significantly influenced by manure type, soil moisture level and incubation period. Poultry manure slurry exerted the highest P and S release under both moisture conditions. Both slurries showed higher potential mineralization, with a lower rate constant for these elements compared to that in their manure states. Hence, appropriate manures should be chosen and applied in the proper quantity to provide exact amounts of nutrients, to increase crops nutrient use efficiency and to formulate correct fertilizer recommendations.

Tomato is in high demand because of its taste and health benefits. In Florida, tomato is the number one vegetable crop in terms of both acreage and value. Because of its high value and wide acreage, it is important for tomato production to be efficient in its water and nutrient use, which may be improved through fertigation practices. Therefore, the objective of this new 7-page article is to disseminate research-based methods of tomato production utilizing fertigation to enhance yield and nutrient use efficiency.
