Abstract
The present investigation was carried out in March 2011 – February 2012 conducted in the experimental Farm, at Fruit Research Farm, Department of Fruit Science, College of Horticulture and Forestry, Central Agricultural University, Paighat, Arunachal Pradesh. The experiment was laid out in Randomized Block Design with nine treatments and three replications. Nine plants for each treatments in a plot were tagged for recording various observation. Uniform cultural practices were given in each treatment. The following treatments were imposed 3.5 and 7 months after planting. T1 control, T2 Foliar spray of ZnSO4 (0.5%), T3 Floliar spray of FeSO4 (0.2%). T4 Foliar spray of CuSO4 (0.2%). T5 Foliar spray of H3BO3 (0.1%). T6 combination of foliar spray of H2BO3 (0.1%) and CuSO4 (0.2%). T7 Combination of foliar spray of ZnSO4 (0.5%) and FeSO4 (0.2%). T 8 Combination of foliar sprays of ZnSO4 (0.5%), FeSO4 (0.2%) and H3BO3 ((0.1%). All the treatments except control were effective in increasing yield, quality and growth. The highest pseudostem height (231.71cm) was observed in T81 while girth (72.85CM), leaf area (12.76m2) and leaf areas index (5.34) were highest in T9. Maximum increase in production of fruits (50.75 t/ha) was recorded in treatment T9 while yield was minimum (33.03t/ha) in T1 control. Better growth and yield were observed in combination of the treatments. The fruit quality in term of TSS,rerducing sugar, total sugar, non-reducing sugar and ascorbic acid were found significant but titrable acidity, pulp-peel ratio and sugar-acid ratio were found to be non significant. The higher results were obtained in T9 (26.15’Brix) for TSS,. T8 (6.61%) for reducing sugar, T9 (17.73%) for total sugar, T9 (11.13%) for non-reducing sugar and T9 (7.23mg/100g) for ascorbic acid. The highest cost benefit ratio was observed in T9 (1:2.72) Hence, the treatment T9 Combination of Foliar spray of ZnSO4 (0.5%), FeSO4((0.2%) and H3BO3 (0.1%) was considered the best treatment among all the other treatment in attaining better growth, quality and yield of fruits.
