A field trial was conducted during 2009-2010 at College Orchard, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, to standardize stage-wise requirement of nutrients in banana cv. Grand Naine (AAA). Treatment T16 where application of 100% RDF (165:52.5:495g NPK plant-1) at 4 critical growth stages, i.e., 40:52.5:25, 30:0:35, 30:0:25 and 0:0:15% at the 3rd, 5th, 7th and 9th months after planting (MAP), respectively, recorded maximum plant height, pseudostem girth and leaf area index. Maximum bunch weight of 32.15kg was recorded in T16. Higher yield was attributed to more number of (i) hands per bunch, (ii) fingers per hand and (iii) per bunch, besides the higher average weight of the finger. Better quality fruits, with higher TSS, total sugars, low acidity and better sugar:acid blend, were obtained in T16. In treatment T16, where 100% RDF was applied, increased N, P, and K content were seen in the index leaf of the crop. Lower soil-available nutrients, viz., N, P, K, at the higher level of split-application at critical stages of the crop revealed, that, the nutrients applied were utilized efficiently. This was reflected in the better yield and quality obtained. Economics were worked out which indicated T16 as giving the highest cost:benefit ratio (1:3.97).Keywords

Attempts were made to estimate molecular diversity present in F3 populations of intergeneric crosses between Carica papaya L. (Var. Pusa Nanha and CP 50) and Vasconcellea cauliflora. Molecular studies revealed that PCR amplification using five ISSR primers in 40 F3 progenies yielded 53 reproducible amplified bands. Of the 53 bands, 44 were polymorphic (83.02%). Polymorphic Information Content (PIC) value ranged between 0.90 (ISSR 807 x 810) and 0.66 (ISSR 834 x 810). Similarity coefficients based on five ISSR markers ranged from 0.05 to 0.96. Maximum similarity was observed for genotypes 1, 4 and 6 of Pusa Nanha x Vasconcellea cauliflora (0.96). Minimum similarity was observed between genotypes 3 and 14 of CP 50 x Vasconcellea cauliflora (0.04). This higher genetic diversity of papaya progenies stands to contribute to development of new varieties and, using the data, further hybridization and selection can be planned.Keywords

Six papaya hybrids, viz., CO-1 × Pusa Nanha, CO-2 × Pusa Nanha, CO-4 × Pusa Nanha, CO-5 × Pusa Nanha, CO-6 × Pusa Nanha and CO-7 × Pusa Nanha, along with their respective parents, were evaluated for fruit yield and quality. Higher fruit yield was recorded in hybrids CO-2 × Pusa Nanha, CO-4 × Pusa Nanha and CO-5 × Pusa Nanha at first harvest. Higher papain recovery was seen in CO-2 × Pusa Nanha and CO-5 × Pusa Nanha and activity of this enzyme was highest in CO-5 × Pusa Nanha. For fruit yield at first harvest, hybrids CO-2 × Pusa Nanha, CO-4 × Pusa Nanha, CO-6 × Pusa Nanha and CO-5 × Pusa Nanha recorded higher heterosis over mid- and better parental values. Fruit yield at first harvest exhibited high genotypic and phenotypic coefficient of variation. Days to flowering had the least genotypic and phenotypic coefficient of variation. Highest heritability estimates were recorded for plant height at first flowering, ascorbic acid content and titrable acidity. Fruit yield at first harvest showed high genetic advance as percentage of mean and the least genetic advance was seen for days to flowering. CO-2 × Pusa Nanha, CO-4 × Pusa Nanha, CO-5 × Pusa Nanha and CO-6 × Pusa Nanha showed better yield and earliness, and are recommended for further evaluation.Keywords

Effect of foliar application of various nitrogenous chemicals on flowering, fruit set and yield of mango cv. Alphonso was studied at the orchard of Horticultural College and Research Institute, Coimbatore, during 2010 - 2011. Maximum number of flowering shoots (68.7%), number of panicles (7.5/m2), panicle length (31.4cm), number of hermaphrodite flowers (282.5/panicle), fruit set (17.0%), number of fruits (146.0/tree) and fruit yield (43.8 kg/tree) was obtained with foliar spray of KNO3 at 2% concentration. Higher content of chlorophyll (1.7g mg-1), carbohydrate (14.5g 100g-1) and nitrogen (1.43%) and higher C/N ratio (10.18) were also recorded in plants sprayed with 2% KNO3, followed by 1% KNO3.Keywords
