Description |
The present investigation was carried out for the “Study of growth, flowering behaviour, yield and quality of mango (Mangifera indica L.) cv. Kesar” during the year 2004-05 and 2005-06 at Agro climatic zone-II, Nanavarachha, Surat. The experiment comprised of 13 treatments [i.e. Mepiquat chloride (100, 150 and 200 ppm), Paclobutrazol (500, 1000 and 1500 ppm), Ethrel (50, 100 and 150 ppm), NAA 10 ppm + 2% Urea and NAA 20 ppm + 2% Urea, water spray and No spray (control)] laid out in a randomized block design and replicated thrice. Effects of these treatments on factors governing flower bud differentiation observations, pre harvest observations, yield parameters and Post harvest observations were recorded. Among all the treatments The emergence of new shoots was significantly higher in T4 (1s t spray of PBZ-500 ppm, 2nd spray of NAA-20 ppm + 2 % Urea and 3rd spray of NAA-20 ppm + 2 % Urea) in both the years and in pooled also. The length of shoot was increased by all the treatments except T12 and T13. The maximum shoot length and width was gained in treatment T4. During both the years and in pooled also the number of leaves per shoot was highest in T4 and it was at par with T1, T5, T6, T7 T8 and T9, while it was lowest in control (T13). Total leaf area per shoot was maximum in control (T13) which was at par with T12, T11 and T10 for both years and in pooled analysis also. In respect to chlorophyll content, it was significantly influenced by various spraying schedule during both years as well as in pooled analysis. The chlorophyll content was highest in T1 (i.e. 1s t spray of MC 100 ppm, 2nd spray of NAA-20 ppm + 2% Urea and 3rd spray NAA- 20 ppm + 2% Urea), which was at par with T2, T7 and T8 for both years of study and in pooled also. Significance difference was found in fresh and dry weight of leaves due to different spraying of bioregulators treatment. T13 (control) registered maximum fresh and dry weight of leaves and it was at par with T1, T2, T3, T7, T10, T11 and T12 for fresh weight of leaves and T1, T2, T3, T7, T8, T9, T10, T11 and T12 for dry weight of leaves during both years as well as in pooled also. While minimum fresh and dry weight of leaves was found in T6. During both the years as well as in pooled analysis the percentage of flowering was highest in T4 and it was at par with T1, T5, T6 and T7. While lowest percentage of flowering was observed in control (T13). With respect to number of flowers per panicles, the maximum number of flowers per panicle was recorded with treatment T4, which was at par with T5 and T6 during first year, T5, T6, T7 and T8 during second year and T5, T6 and T7 in pooled analysis. While minimum number of flowers per panicle was recorded in control (T13). Number of initial fruit set was significantly increased with the treatment T4 during second year and pooled, while it was found to be non-significant in first year. The number of initial fruit set was lowest in control (T13). The per cent fruit retention at pea, marble and mature stage was significantly increased with the treatment T4 during both the years as well as in pooled also. The lowest per cent fruit retention at pea, marble and mature stage was noted in control (T13). The length and breadth of fruit were significantly increased by the treatments T4 over control for both the years of study and in pooled also, The mature fruit weight was increased with the treatment T4, and it was at par with T1, T5, T7, T8 and T9 during first year, T1, T5, T6 and T7 during second year and T1, T5, T7 and T8 in pooled analysis. The mature fruit weight was minimum in control (T13) for both the years and in pooled also. The yield per tree was significantly higher in treatment T4 for both years of study as well as in pooled also. And it was at par with T5, T6, T7 and T8. Control (T13) recorded lowest yield per tree during both years and in pooled also. During both the years and in pooled analysis the physiological loss in weight was minimum in treatment T4 and it was on same bar with T5 and T6 during first year, T5 during second year and pooled analysis while PLW was maximum in control (T13). Regarding the effect of physiochemical parameters, treatment T4 was found superior in all physiological observations such as average number of days taken to ripeness, firmness of fruit, fruit pulp : stone ratio and fruit pulp : peel ratio. The physicochemical parameters of fruits viz., organoleptic test, total soluble solids, reducing sugars, total sugars, acidity and ascorbic acid content were found to be nonsignificant with respect to different spraying schedules. Thus, it can be concluded that, treatment T4 (1s t spray of PBZ-500 ppm, 2nd spray of NAA-20 pm + 2% Urea and 3rd spray of NAA-20 ppm + 2% Urea) was found better with respect to growth, flowering behaviour of tree as well as yield and quality of mango (cv. Kesar) fruit. |
