“…The evaluation of bio-fertilizers on growth and establishment of mango grafts var.Alphonso under poly-house condition showed that the biofertilizers, nitrogen fixer, phosphate solubilize, bio control agent and phosphorous mobilize in the form of Azospirillum spp., Pseudomonas striata, Pseudomonas fluorescens and VAM respectively had increased the growth parameters. The growth and establishment was significantly superior as reported by Shankarappa et al 2018. In case of three and four months old acid lime seedlings (Citrus aurantifolia Swingle) cv.…”

Experiment was conducted in poly-house at College of Horticulture, Bengaluru to study the effect of Bio fertilizersand organic amendments on growth and establishment of pummelo under nursery condition during 2019-20. The nursery were established in potting mixture; sand, soil and farm yard manure in the ratio of 2:1:1 (Sand: Soil: FYM;) taken in polythene bags of size 12 cm x 24 cm. Applied with biofertilizers such as Azospirillum spp., Phosphorus solubilizing bacteria (PSB), Pseudomonas fluorescents, @ 6 g per plant (single / dual / combinations 6 g only) plus Vesicular Arbuscular Mycorrhiza (VAM), soil based bio-fertilizers @ 6 g per plant. A total of nine treatments were tested in four replications. The results at the end of 120 days showed that the inoculation of consortium of three bio-fertilizers; Azospirillum, spp. Phosphorus solubilizing bacteria and VAM had produced significantly highest seedling height (36.32 cm), seedling girth (4.67 mm), number of leaves (23.10 no.), leaf area (28.25 cm 2 ), fresh and dry Weight of shoot (17.47 and 7.16g respectively) in T3 treatment. The maximum fresh and dry weight of root (10.02 and 5.07 g), number of primary and secondary roots (37.95), length of primary root (35.95 cm) and root volume (10.34 cm 3 ) was recorded the treatment Azospirillum,, Phosphate solubilizing bacteria and Pseudomonas fluorescens and VAM at the end of 120 days in nursery.

“…In mango, the application of Azotobacter along with Phosphorus Solubilizing Bacteria (PSB) and Vermicompost at the concentration of 50g, 50g, 3kg respectively can increase the plant growth parameters particularly girth of the rootstock, height of the plant of the mango tree [7]. The inoculation of three biofertilizers viz; Azospirillum, Pseudomonas fluorescence and Vesicular Arbuscular Mycorrhiza (VAM) in the potting mixture of grafted Alphonso mango enhance the height of the plant [8].…”

The experiment was conducted to study the influence of fertilizers and bioinoculants on growth characteristics of guava cv. L-49 at Fruit Research Station Imaliya, Jawaharlal Nehru Agriculture University, Jabalpur, Madhya Pradesh, during 2022-23 and 2023-24 on twelve-year-old guava trees planted at 3.0 m x 3.0 m spacing. The experiment was carried out in factorial RBD with three replications. The data revealed that different levels of nutrients and bioinoculants alone and in combinations significantly influenced the growth parameter. The maximum increase in plant height (12.16%) & (12.46%), canopy spread E-W (14.15%) & (14.45%), canopy spread N-S (14.33%) & (14.72%) and stem girth (11.19%) & (10.07%) were recorded in N2 (100%RDF), during both years of experimentation respectively. With respect of bioinoculants, the maximum plant height (11.48%) & (11.71%), canopy spread E-W (13.24%) & (13.61%), canopy spread N-S (14.05%) & (14.44%) and stem girth (9.72%) & (8.85%) were observed in B5 (Bactobooster 200 ml), during both years respectively. Among the treatment combinations, T10 (100% RDF + Bactobooster200ml) was found superior with respect of the maximum increase in plant height (12.86%) & (13.09%), in canopy spread E-W (15.77%) & (16.11%), canopy spread N-S (16.16%) & (16.66%) and in stem girth (12.54%) & (11.01%) during both the years of experimentation respectively followed by T15 (75% RDF + Bactobooster 200 ml) and minimum was recorded in control.

“…Therefore, organics such as bovine manure, sugar cane bagasse (De Lima et al, 2001) or biofertilizers are found to be environmentally healthy despite requiring extra care in handling (Bhardwaj et al, 2014). Moreover, organics have been a joice in modern agriculture because they promote and stimulate gradual release of nutrients into the soil (Serrano et al, 2018;Shankarappa et al, 2017). Based on this realization, several studies have explored the use of vermicompost and sugar cane bagasse (De Lima et al, 2001), carbonized rice or coco nut fiber (Correia et al, 2003) and pine burk (Serrano et al, 2016) in cashew seedling production systems.…”

“…In rice and maize, biofertilizers have been found to increase yield in 10 and 28% respectively (Walker, 2009). On cashew seedlings production systems, biofertilizers, have been found to improve total dry matter of plantlets in Brazil as well as in India (Melo Filho et al, 2015 andShankarappa et al, 2017). Our focus is how to use these fertilizers to ensure seedling size uniformity on time for grafting.…”

Seed born cashew (Anacardium occidentale L) seedlings are planted directly when they are produced from polyclonal orchards. In a common scenario, cashew seedlings are grafted before transplanting. For this purpose, adjusting the size between scions and rootstock is highly important for the success of grafts and it can be achieved through a visual selection of scions. However, when working with large numbers of seedlings physical and visual selection becomes laborious and time consuming for the workers. Therefore, creating uniformity in seedlings size before grafting is crucial. We present experimental results showing the linear regression between the fertilization level and seedling stem size. Two experiments were conducted in Mozambique: One at Nassuruma cashew Research Station, Nampula province, following a Completely Randonmized Block Design (CRBD), seven treatments, ten bags per treatment and five replicates. The treatments consisted of a fertilizer organically composted from cashew nut shells and applied at rates of 0, 4, 8, 16, 32, 40 and 48% of the total amount of soil in each bag. The second experiment was carried out at Chizavane nursery, in Gaza Province, also based on CRBD, in factorial arrangement of 4 and 3 levels of Kelp and Stimu biofertilizers respectively. Two stem size variables, diameter and height, were considered and data collected at 120 days after seedlings emergence in Nampula and 45 days after emergence in Gaza Province. Polynomial or simple regression analysis model for stem diameter and plant height was performed. The stem diameter was linearly described as an increasing equation. The height was also linearly related to fertilizer but following a decreased equation. We concluded that applying appropriate dosage of fertilizer in the soil or on the leaves could adjust the stem size of the rootstock required for grafting and therefore adjust the stem to the size of scions available. The treatments with high level of Kelp, Stimu and cashew compost fertilization resulted in increase of 8,5%, 6% and 16,6% of diameter respectively. However, the treatments caused a reduction of height at rate of 14,3%, 3,2% and 25,08% respectively. The stem and scion size adjustment are highly important for increasing the grafting success rate in a cashew nursery.
