Abstract
Anexperiment titled “Influence of Lime and Boron on the Performance of Broccoli (Brassica oleraceae L.var. italica Plenck) under protected condition” was carried out at Vegetable Research Farm, Dept. of Vegetable Science, College of Horticulture and Forestry, CAU, Pasighat, Arunachal Pradesh in the year 2020-21 using ‘Green Magic’ (F1 hybrid) to study the effect of different levels of lime and boron treatment on growth, yield and quality of broccoli. The experiment was carried out in a two factor Factorial Randomised Block Design (FRBD) with 16 treatment combination in 3 replications. The treatment details are Factor 1 (L0: 0 kg/ha lime; L1: 500g/bed @ 2500 kg/ha lime; L2: 700g/bed @ 3500 kg/ha lime; L3: 900g/bed @ 4500 kg/ha lime), Factor 2 (B0: 0% borax spray; B1: 0.2% borax spray; B2: 0.3% borax spray; B3: 0.4% borax spray). The treatment combinations were: T1: L0B0(Control), T2: L0B1 (0g/bed lime + 0.2% borax as foliar spray), T3: L0B2 (0g/bed lime + 0.3% borax as foliar spray), T4: L0B3 (0g/bed lime + 0.4% borax as foliar spray), T5: L1B0 (500g/bed lime + 0% borax as foliar spray), T6: L1B1 (500g/bed lime + 0.2% borax as foliar spray), T7: L1B2 (500g/bed lime + 0.3% borax as foliar spray), T8: L1B3 (500g/bed lime + 0.4% borax as foliar spray), T9: L2B0 (700g/bed lime + 0% borax as foliar spray), T10: L2B1 (700g/bed lime + 0.2% borax as foliar spray), T11: L2B2 (700g/bed lime + 0.3% borax as foliar spray), T12: L2B3 (700g/bed lime + 0.4% borax as foliar spray), T13: L3B0 (900g/bed lime + 0% borax as foliar spray),T14: L3B1 (900g/bed lime + 0.2% borax as foliar spray), T15: L3B2 (900g/bed lime + 0.3% borax as foliar spray), and T16: L3B3 (900g/bed lime + 0.4% borax as foliar spray). The result obtained by statistical analysis of the recorded data on effect of lime and boron was found to be significant. Treatment combination of 500g lime/bed + 0.3% borax spray i.e., T7 showed the best result in terms of plant height (67.38cm), leaf length (49.66cm), number of leaves (21.23), plant spread 70cm (East to West) and 72.86cm (North to South) and stem height (36.25cm).T11(700g lime/bed + 0.3 % borax) recorded maximum leaf width (23.80cm) and stem girth (4.09cm). In terms of yield parameters, T7 gave the best results in minimum days to harvest (81.10), head diameter (16.04cm), fresh head weight (310.74g), dry head weight (27.63g), yield per plot (3.12kg) and yield per hectare (15.6 t). The least days to bud initiation (61.23) was recorded by T11. Highest values for quality parameters like TSS (7.66oBrix),vitamin-A content (155.86 mg/100g), ascorbic acid (110.83 mg/100g), carbohydrates (5.88%) and total chlorophyll (1.02 mg/g) were found to be highestinT7amongst all other treatment combinations. The control treatmentT1, gave the least values in all the parameters among all the 16 treatment combinations.
Description
Anexperiment titled “Influence of Lime and Boron on the Performance of Broccoli (Brassica oleraceae L.var. italica Plenck) under protected condition” was carried out at Vegetable Research Farm, Dept. of Vegetable Science, College of Horticulture and Forestry, CAU, Pasighat, Arunachal Pradesh in the year 2020-21 using ‘Green Magic’ (F1 hybrid) to study the effect of different levels of lime and boron treatment on growth, yield and quality of broccoli. The experiment was carried out in a two factor Factorial Randomised Block Design (FRBD) with 16 treatment combination in 3 replications. The treatment details are Factor 1 (L0: 0 kg/ha lime; L1: 500g/bed @ 2500 kg/ha lime; L2: 700g/bed @ 3500 kg/ha lime; L3: 900g/bed @ 4500 kg/ha lime), Factor 2 (B0: 0% borax spray; B1: 0.2% borax spray; B2: 0.3% borax spray; B3: 0.4% borax spray). The treatment combinations were: T1: L0B0(Control), T2: L0B1 (0g/bed lime + 0.2% borax as foliar spray), T3: L0B2 (0g/bed lime + 0.3% borax as foliar spray), T4: L0B3 (0g/bed lime + 0.4% borax as foliar spray), T5: L1B0 (500g/bed lime + 0% borax as foliar spray), T6: L1B1 (500g/bed lime + 0.2% borax as foliar spray), T7: L1B2 (500g/bed lime + 0.3% borax as foliar spray), T8: L1B3 (500g/bed lime + 0.4% borax as foliar spray), T9: L2B0 (700g/bed lime + 0% borax as foliar spray), T10: L2B1 (700g/bed lime + 0.2% borax as foliar spray), T11: L2B2 (700g/bed lime + 0.3% borax as foliar spray), T12: L2B3 (700g/bed lime + 0.4% borax as foliar spray), T13: L3B0 (900g/bed lime + 0% borax as foliar spray),T14: L3B1 (900g/bed lime + 0.2% borax as foliar spray), T15: L3B2 (900g/bed lime + 0.3% borax as foliar spray), and T16: L3B3 (900g/bed lime + 0.4% borax as foliar spray). The result obtained by statistical analysis of the recorded data on effect of lime and boron was found to be significant. Treatment combination of 500g lime/bed + 0.3% borax spray i.e., T7 showed the best result in terms of plant height (67.38cm), leaf length (49.66cm), number of leaves (21.23), plant spread 70cm (East to West) and 72.86cm (North to South) and stem height (36.25cm).T11(700g lime/bed + 0.3 % borax) recorded maximum leaf width (23.80cm) and stem girth (4.09cm). In terms of yield parameters, T7 gave the best results in minimum days to harvest (81.10), head diameter (16.04cm), fresh head weight (310.74g), dry head weight (27.63g), yield per plot (3.12kg) and yield per hectare (15.6 t). The least days to bud initiation (61.23) was recorded by T11. Highest values for quality parameters like TSS (7.66oBrix),vitamin-A content (155.86 mg/100g), ascorbic acid (110.83 mg/100g), carbohydrates (5.88%) and total chlorophyll (1.02 mg/g) were found to be highestinT7amongst all other treatment combinations. The control treatmentT1, gave the least values in all the parameters among all the 16 treatment combinations.
From the experiment, it was found that T7: L1B2(500g lime + 0.3% borax) is the most suitable treatment combination for the best result of growth, yield and quality in broccoli under protected condition.
