ECO FRIENDLY NUTRIENT MANAGEMENT PRACTICES FOR YIELD AND SOIL ORGANIC CARBON, IN BANANA
To study the productivity of banana by the effect of nutrient management practices, field investigations was conducted from 2010-2012 at Northern Block Farm of Agricultural Research Station, Bhavanisagar (TNAU) of Tamil Nadu. Study results revealed that, when 100% recommended dose of fertilizer (RDF) is applied, along with 40% Wellgro soil, maximum number of hands (10.2 and 10.3) were recorded, along with the maximum number of fingers (136.3 and 145.2), total yield (72.8 and 77.1 t/ha) and bunch weight (23.9 and 25.3 kg/plant) during 2010-11 and 2011-12, respectively. By the integrated nutrient management practices, there was an influence of the quality parameter of the study in banana during both the years. With regard to organic carbon, when either 75 or 100 % of RDF is applied along with FYM @ 10 kg plant-1 or WG organic manures, maximum accumulation of carbon was found to be recorded in soil. When nutrient management practices are done, i.e., when there was a combined application of 40% Wellgro soil or Cow based Farm Yard Manure @ 10kg plant-1 with recommended dose of fertilizers to banana has been observed to be a good option that helps to increase soil nutrient status and yield parameters under climate and soil condition in Tamil Nadu, India.

Organic bio-slurry soil amendments' effect on soil chemical properties and the growth traits of tissue culture banana (TCB) were studied from 2017 to 2020 at Uganda Martyrs University Farm. Mpologoma and Kibuzi banana cultivars of the AAB East Africa Highland cultivar were treated with NPK fertilizer and two bio-slurries at different rates. Treatments included the control (CNTRL), 3810 L/ha banana bio-slurry (BBS1), 7620 L/ha banana bio-slurry (BBS2), 11,430 L/ha banana bio-slurry (BBS3), 3810 L/ha cow dung bio-slurry (CDBS1), 7620 L/ha cow dung bio-slurry (CDBS2), 11,430 L/ha cow dung bio-slurry (CDBS3) and 300 kg/ha NPK. The soil was analyzed for variations in pH, nitrogen (N), phosphorous (P), potassium (K) and organic matter (OM) at different depths. The growth parameters of TCB were recorded months after planting (MAP). Soil amended with 11,430 L/ha bio-slurry had high potassium, nitrogen, and organic matter contents for the three soil sampling depths (0-8, 8-16, 16-32 cm), and soils amended with CDBS had higher K, N and OM contents than those amended with BBS. The Soils amended with CDBS3 recorded the maximum pseudostem girth and the number of suckers for both cultivars. Soils amended with BBS3 recorded the highest total number of leaves for the Mpologoma cultivar. The interaction effect of the bio-slurry on the variation of stem girth and height, the number of suckers, and the total number of leaves at 12 MAP for Mpologoma and Kibuzi cultivars was significant (p < 0.05). The banana cultivar and the bio-slurry interaction significantly (p < 0.05) affected the number of clusters per bunch, the number of fingers per cluster, the weight of the bunch (kg) and weight per cluster (kg). Amending soils with 11,430 L/ha of banana and 11,430 L/ ha of cow dung bio-slurries provides the soil with sustainable nutrients for TCB growth up to 12 MAP and sustainable environmental health in the long run.
A field experiment was laid out in a randomized block design with 5 treatments and 4 replications consisting of recommended dose of fertilizers (RDF) and RDF was combined with organic manures (FYM & Vermicompost) and biofertilizers [azotobacter, azospirillum and Phosphate solubilising bacterial (PSB)] at different combinations to know their impact on yield and soil fertility status of tissue culture banana during 2013 and 2014. The experiments consisted of five treatments T 1 (control), T 2 (100% RDF (300💯300 g NPK)/plant), T 3 (100% RDF +75 g biofertilizers), T 4 (100% RDF +100 g biofertilizer) and T 5 (100% RDF +125 g biofertilizer). The biofertilizers are applied in form of Azotobacter, Azospirillum & PSB inoculated with organic manure (FYM & Vermicompost). The study indicates the best results in post harvest soil characteristics like organic C, EC, pH, available N, P and K value.

Banana (Musa spp) is considered as one of the most important fruit crops in Egypt, where it occupy an area of 27.5 thousand ha. Field experiments on banana cv. Grand Nain for two consecutive seasons (2016 and 2017) were conducted in Horticulture Research Station located in El-Kanter Elkharia, Kaluobia Governorate. The main objective of this study was to investigate the possibility of reducing the mineral fertilizers applied to the banana crop by using compost and potassium silicate treatments. Three rates of compost (15, 20 and 25 kg per mate) were applied with 50% of the recommended rate of mineral fertilizers along with or without potassium silicate at a rate of 60 ml per mate. These treatments were compared with recommended rates of mineral fertilizers mixed with and without potassium silicate. Obtained results showed that application of compost led to enhance all studied parameters and recorded highly significant differences particularly under the treatments combined with potassium silicate and 50% of the recommended rate of mineral fertilizers. The highest level of compost with potassium silicate treatment recorded the uppermost values of growth, yield and quality of banana fruits. Moreover, the same treatment recorded significant increments in total sugar and T.S.S% in fruits as compared with the recommended dose of mineral fertilizers.
A field experiment was conducted over eight crop cycles comparing whole water suckers (WWS) without root and leaf pruning with tissue-cultured (TC) plants, both planting materials with or without nematicide application on plant growth and yield variables. Averaging the eight crop cycles, TC plants produced heavier (P = 0.0005) bunches with greater number of hands (P = 0.0003) than those originated from WWS plants. The nematicide application did not affect any of those variables in any of both planting materials. Follower sucker height, girth and its number of broad leaves at flower emergence of its mother plant were similar in both planting materials and not affected by the nematicide application. Ratooning index did not differ between planting materials. Bunch weight (P = 0.0001), fruit tick (P = 0.0001), number of fruits in the second hand (P = 0.0001) and leaves at harvest (P = 0.0001) and ratooning index (P = 0.0001) differed among ratoon crops. The percentage of missing plants was higher (P < 0.0331) in WWS plants during the R0, R1 and R2. Between plants treated or untreated with nematicide the percentage of missing plants was similar and low. TC plants had lower R. similis than WWS, without differing between nematode control methods, and in the WWS the nematicide application resulted in 53% less nematodes (P < 0.0001) compared to the untreated control. The results encourage continuing with the use of tissue culture plants in areas new to bananas or replanting areas where the fruit is for export markets. However, for domestic consumption or even in plantations where the fruit is advocated to export markets, but if there are restrictions of TC plants by cost or availability, the results obtained with WWS show high potential for their use in frequently replanting areas, especially those areas sowing at high plant densities, where the demand of planting material is high. The WWS health should be improved taken them from plantations free of nematodes in order to reduce the nematode potential infection.

Major area under banana cultivation in Pakistan consists of a single cultivar "Dwarf Cavendish" called "Basrai". Quality of banana relies on the available nutrients in soil. Under poor fertility and organic matter scenario coupled with high requirement of banana, this study evaluated the combined effect of organic (farm manure and composted pressmud) and inorganic (NPK) sources of nutrients on nutrient composition of locally grown banana. Application of full NPK (500-250500 kg ha) increased the fruit P (0.08-0.12%), K (0.77-1.50%) and Zn (1.74-2.17 mg kg) over full N and the respective values further increased to 0.14 and 0.22%, 2.28 and 1.79% and 2.42 and 2.21% with farm manure and composted pressmud additions. Moreover, there was a non-significant increase in N and significant one in Cu and Fe. There was no additional benefit of 1.25 NP. In fact, the higher rates i.e. full NPK and 1.25 NP reduced the micronutrient contents of fruit due to dilution effect. Howev...

An experiment was carried out in banana cv. Grand Naine to evaluate the effect of three different plant densities with three levels of fertilizer which was laid out in factorial RCBD design with three replications. During all the stages of growth, except plant height, all the vegetative growth parameters were higher in lowest plant density (2.0 x 2.0 m) and lower in higher plant density (1.5 x 1.5 m). The highest plant height (207.67 and 205.61 cm) and yield (108.33 and 101.95 tons/ha) was registered in higher plant density in both the plant and ratoon crop respectively. While, the lowest plant height (197.25 cm and 194.19 cm) and yield (74.26 and 69.38 tons/ha) was observed in lower plant density in both the seasons respectively. In case of fertilizer application, the significant result was obtained for growth and yield of banana. The highest growth and yield parameters was found in F2 (125 % RDF) whereas the lowest was registered in F3 (75 % RDF). For combined effect of plant density and fertilizer on growth and yield parameters, the treatment S3 x F2 (2 x 2 with 125 % RDF) recorded higher values except plant height and yield than other combinations.

Considerable attention has been given to the development of new nutritional management strategies that can contribute to banana production be overestimated. The present study was motivated by the possibility that fertilizer application in front of the daughter plant might be more effective than application to the total banana production area. This study aimed to determine the most suitable site for soil collection to evaluate the chemical properties when fertilizer is applied in front of the daughter plant; to evaluate the efficacy of organic-mineral fertilizer in terms of soil nutrient availability, and to evaluate the effect on banana production. The experiment was conducted in three consolidated areas of banana plantation in Santa Catarina State. The effects of the combination of two main factors were evaluated: three fertilizer sources (mineral, mineral + organic compost or organic-mineral) and two application management (total area or in front of the plants), together with time (three years) and location (three municipalities). Each treatment was evaluated using a grid containing 20 banana plants (spaced at 2.5 × 2.5 m), with three replications of two plants in the central part. The experiment was arranged in a completely randomized design with three replicates. The use of a mineral source reduced the pH over the years, regardless of the application technique. Application of fertilizers in front of the daughter plant increased available P and K in the soil, compared to the application of fertilizers to the total area "uniformly distributed between banana planting lines and between plants". In addition, the increase in soil P content was higher using organic-mineral sources. The nutrient contents in the banana leaves did not differ according to the fertilization source. The application of fertilizers in front of the daughter plant optimized banana fertilization and increased fruit production. Under these fertilization conditions, soil for chemical analyses should be collected at around 0.70 m from the site of fertilizer application.
