EFFECT OF PRE-HARVEST APPLICATION OF NAA, Ca, AND B ON FRUIT DROP, YIELD, AND QUALITY OF THAILAND BER (Ziziphus mauritiana)
(2023) PASWAN, KARISHMA; Saikia, Ananta
The present study was carried out to investigate the beneficial effects of the pre-harvest spray of NAA, calcium, and boron on fruit drop, yield, and quality of Thailand ber (Ziziphus mauritiana) at the Experimental Farm, Department of Horticulture, AAU, Jorhat-13 during 2022-2023. The spraying with NAA @ 20 ppm + B @ 0.5%) resulted maximum fruit set (4.68%), lesser fruit drop (53.28%), the highest yield (18.12 kg/tree). CaCl2@ 1% spray gave maximum shelf life (13.5 days) with the minimum PLW. The highest B: C ratio (1.81) was found in NAA @ 20 ppm + B @ 0.5 % application based on the economics of cultivation indicating that spraying of NAA 20 ppm in combination with B 5% is the most profitable approach for minimizing fruit drop and maximizing production.

BIOCHEMICAL CHARACTERIZATION OF SOME CITRUS GERMPLASM OF ASSAM
(2023) Saikia, Kareena; Borthakur, Pritom K.
Ten genotypes representing each of the five groups of Citrus were collected from AAU-Citrus and Plantation Crops Research Station, Tinsukia and Regional Research Centre for Citrus (CCRI, ICAR), Biswanath Chariali. Morphological characterization of fruits was carried out as per the descriptors developed for Citrus by IPGRI (1999), Rome, Italy and the results indicate the presence of significant variability among genotypes. Biochemical characterization revealed that moisture content ranged from 92.51% to 84.30% in the pulps and from 83.32% to 70.20% in the peels. Juice pH, TSS and titratable acidity ranged from 3.90 to 2.60, 11.40 to 5.30 ̊Brix, and 0.97% to 4.71% respectively in different genotypes. The ash content varied from 2.83% to 5.96% in the pulps and from 2.53% to 5.69% in the peels. Similarly, the reducing sugar in the juice varied from 2.06% to 6.72% and non-reducing sugar varied from 0.48% to 4.15%. The total sugar percentage ranged from 9.36%-2.54% in the juice. The crude protein content was found to be high and ranged from 5.60%-9.16% in the pulps and 5.60%-13.83% in the peels. Organic acid and water-soluble vitamins were quantified using Ultra High-Performance Liquid Chromatography (UHPLC) and it was revealed that citric acid was present in the maximum amount followed by malic acid. Among the water-soluble vitamins, the thiamine concentration was found to be the highest. Quantification of the minerals was carried out by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The results show that both major and minor minerals were present in significant amounts in both the peel and pulp of the Citrus species. The essential oil content (%) was estimated and it was found to range from 0.26% to 0.83% in the fresh peel of the Citrus genotypes. Analysis of the essential oil that was carried out by Triple Quadrupole Gas-Chromatograph Mass-Spectroscopy (TQGC-MS/MS) showed the presence of D-limonene, α-pinene, ß-pinene, γ -terpinene, α-terpineol, terpinene-4-ol, linalool as the major compounds. Aromatherapeutic, antioxidant, antifungal and insect-repellent compounds such as eucalyptol, thymol, geraniol and nerol were also reported in certain species.

EFFECT OF EDIBLE COATING IN ASSAM LEMON (Citrus limon Burm.) DURING STORAGE
(2023) Das, Juman; Choudhury, Shahida
The Northeast region of India is a rich treasure of different Citrus species. Assam lemon is one of the important Citrus species and it is indigenous to Assam. The main storage problems of lemon fruits are browning & shrinking of peel, loss of green colour, loss of firmness, and reduced juice content. Providing non-hazardous edible coating would permit the possibility to reach the distant markets in fresh form. Use of CMC (Carboxy Methyl Cellulose) as exterior coating along with Sodium Benzoate and Bees Wax coating can increase the shelf life of Assam Lemon. The present investigation was carried out in the Laboratory, Department of Horticulture, Assam Agricultural University, Jorhat during the year 2022 -2023 with the objectives to evaluate the effect of edible coating on the qualitative changes of Assam lemon during storage and to find out the suitable edible coating treatment for shelf life extension. The treatments includes combination of Carboxy Methyl Cellulose, propylene glycol, sodium benzoate viz., To (Control), T₁ (1% CMC + 2% Propylene Glycol), T₂ ( 3% CMC + 2% Propylene Glycol), T₃ (5% CMC + 2% Propylene Glycol), T₄ (1% CMC + 2% Propylene Glycol + Sodium Benzoate 500 ppm), T₅ (3% CMC + 2% Propylene Glycol + Sodium Benzoate 500 ppm), T₆ (5% CMC + 2% Propylene Glycol + Sodium Benzoate 500 ppm), T₇ (Bees wax 1%), T₈ (Bees wax 2%). The fruits were stored in corrugated fibre boxes. Physical, biochemical and sensory evaluation was done at every 5 days interval. Different observations recorded were physiological loss in weight (%), fruit weight (g), specific gravity, juice content (%), peel browning (%), days to colour change, TSS (0Brix), titrable acidity (%), TSS/acid ratio, reducing sugar (%), non-reducing sugar (%), total sugar(%), ascorbic acid (mg/100 ml ), pectin (%), chlorophyll (mg/g), colour, texture and microbial analysis (log cfu/ml).The highest juice content was recorded in T₅(39.59%),the highest TSS was recorded in T₅(6.270Brix), the highest specific gravity was observed in T₆(1.02), the highest titratable acidity was recorded in T₅(3.42%) on 25th day of storage. The results of the experiment revealed that the application of treatments had significant effect on various biochemical parameter of lemon fruit during storage. The treatment T₅ (3% CMC + 2% Propylene Glycol + Sodium Benzoate 500 ppm) showed better results followed by T₆ (5% CMC + 2% Propylene Glycol + Sodium Benzoate 500 ppm) during storage. T₅ treatment (3% CMC + 2% Propylene Glycol + Sodium Benzoate 500 ppm) was superior as an edible coating and retained better quality with extended storage life as compared to all other treatment.

(2023) VINOD, DOKKA VARA; Alam, Sheriful
The present investigation was carried out with the principle objective to study the variability, heritability, character association and path analysis for morphological and quality parameters in orange-fleshed sweet potato genotypes at an Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during the year 2022-2023. Analysis of variance revealed significant differences for all the morphological and quality characters viz., vine length (cm), internodal length (cm), vine weight per plant (g), fresh weight of whole plant (g), dry weight of whole plant (g), plant dry matter content (%), fresh weight of tuber (g), dry weight of tuber (g), tuber dry matter content (%), length of the tuber (cm), diameter of tuber (cm), number of tubers per plant, marketable tuber yield per plant (g), marketable tuber yield per hectare (t/ha), total soluble solids (°Brix), total carotenoids (mg/100g), starch content (%), total sugars (%), reducing sugars (%), non-reducing sugars (%) and shelf life (days). High PCV, GCV and high heritability in conjunction with high genetic advance as per cent of mean were observed for morphological parameters viz., vine length (cm), internodal length (cm), vine weight per plant (g), fresh weight of whole plant (g), dry weight of whole plant (g), fresh weight of tuber (g), dry weight of tuber (g), diameter of tuber (cm), number of tubers per plant, marketable tuber yield per plant (g), marketable tuber yield per hectare (t/ha) and quality parameters like total carotenoids (mg/100g), starch content (%), total sugars (%), reducing sugars (%), non-reducing sugars (%) and shelf life (days) indicates the preponderance of additive gene action governing the inheritance of these characters and offers the best possibility of improvement through simple selection procedures. Correlation study revealed that yield can be improved by selecting genotypes having more vine weight per plant, fresh weight of plant, dry weight of plant, fresh weight of tuber, dry weight of tuber and diameter of tuber. The highest positive direct effects on marketable tuber yield per plant was shown by fresh weight of whole plant, plant dry matter content, dry weight of tuber and diameter of tuber. The highest negative direct effects were exhibited by vine weight per plant, dry weight of whole plant, tuber dry matter content and number of tubers per plant. Characters having high positive direct effects along with positive significant correlation with marketable tuber yield per plant can be directly selected and simultaneously the characters which show high positive indirect effects can also be selected for the improvement of yield.

(2023) Sharma, Bedanta; Kachari, Manisha
A field experiment was conducted during 2022-2023 at the experimental farm, Department of Horticulture AAU, Jorhat to study the effect of planting geometry and the impact of nutrient management on growth, yield and quality of yard long bean (variety Red Ribbon). The experiment was laid out in factorial randomized block design (FRBD) consisting of two factors viz., spacing and nutrient dose with three replications. The two spacing were S1 (60 cm × 45 cm) and S2 (60 cm × 30 cm) with five nutrient doses of T0 (control), T1 (15:35:20 kg NPK/ha + 4 t FYM/ha), T2 {15:35:20 kg NPK/ha + 2 t vermicompost/ha + biofertilizer (rhizobium + PSB)}, T3 (25:50:30 kg NPK/ha + 4 t FYM/ha) and T4 {25:50:30 kg NPK/ha + 2 t vermicompost/ha + biofertilizer (rhizobium + PSB)}. The treatments brought significant influences on the various parameters except a few. The growth parameters like number of branches (21.76), number of leaves/plant (87.00), number of pickings (9.73) days to initiation of 50 % flowering (35.49) and days to first picking (43.89) performed their best in the spacing S1 whereas the maximum vine length (198.39 cm) was observed in S2. The maximum values for yield attributing parameters like length of pod (39.60 cm), girth of pod (2.13 cm), weight of green pod (10.60 g), number of pods per plant (42.42), pod yield per plant (0.35 kg) and for quality and biochemical parameters like carbohydrate (7.99 %), protein (2.97 g/100g), fibre content (3.04 %) and anthocyanin content (26.53 mg/100g) were observed in the spacing S1 whereas the maximum pod yield per plot (3.66 kg) and pod yield per hectare (169.48 q) were observed in S2. In case of nutrient dose, the maximum vine length (223.00 cm), number of branches (24.00), number of leaves per plant (106.00), number of pickings (10.50), length of pod (43.17 cm), girth of pod (2.23 cm), weight of green pod (11.00 g), number of pods per plant (47.88), pod yield per plant (0.44 kg), pod yield per plot (4.33 kg) and pod yield per hectare (200.62 q) were observed in the nutrient dose T4 with T3 being at par in many of the parameters. The maximum carbohydrate content (8.11 %), protein content (3.11 g/100g) and anthocyanin content (29.31 mg/100g) were observed in nutrient dose T4 while the maximum ascorbic acid content (9.98 mg/100g), fibre content (3.43 %) and ash content (0.66 %) were observed in T3. The maximum values for soil parameters like organic carbon (0.64 %), available N (253.2 kg/ha), available P (39.7 kg/ha) and available K (141.0 kg/ha) were observed in T4 whereas the maximum soil pH (5.23) was observed in T0. The interaction of both the factors also brought significant influences on the parameters with the parameters like number of branches (25.00), number of leaves per plant (107.67), number of nodes (73.67), number of pickings (10.67), length of pod (45.33 cm), girth of pod (2.37 cm), pod yield per plant (0.46 kg), carbohydrate content (8.23 %) and protein content (3.23 g/100g) performing the best in the treatment interaction T4S1 while vine length (228.00 cm), pod yield per plot (4.96 kg) and pod yield per hectare (229.63 q) recorded their maximum values in T4S2. Computation of economics of production revealed that the maximum gross return (Rs. 918518.52) and net return (Rs. 704693.52) were also observed in T4S2 but the highest B:C ratio (3.53) was observed in T3S2.

Crop Regulation in lemon var. Assam lemon (Citrus limon L. Burm.) by pruning
(2023) Goswami, Anwesha; Hazarika, D. N.
The present investigation entitled "Crop regulation in lemon var. Assam lemon (Citrus limon L Burm)” by pruning" was conducted during 2022-2023 at the ICR farm for field experimentation and in the laboratory for qualitative analysis of fruits in the Department of Horticulture, Biswanath College of Agriculture, AAU, Biswanath Chariali with three objectives: (a) to study the effect of pruning on growth, yield and quality of Assam lemon, (b) to study the effect of time of pruning on growth, yield and quality of Assam lemon and (c) to make the fruits available during the lean period particularly during November to February. The experiment was laid out in RBD with 3 replications and 12 treatments. Each treatment consisted of two plants and accordingly 72 plants were selected for conducting the experiment. Pruning considered as treatments were carried out from 1st May, 2022 to 15th October, 2022 at 15 days interval. The results revealed that both the pruning and time of pruning significantly influenced the vegetative growth and production of Assam lemon fruits. Among the treatments, the highest increase in plant height (18.82%) and number of laterals (4.62) per primary shoot was observed in T1 (pruned on 1stMay). Leaf production per terminal shoot was highest (19.33) in T2 (pruned on 15 May) closely followed by T1 (19.22). Shortest duration (18.66 days) for new shoots emergence after pruning was recorded in T6 (pruned on 15th July) while longest period (26.50 days) was observed in plants pruned on 15th October (T12) but the plants under this treatment produced first flower buds within shortest period (43.83 days) from the date of pruning. Days required to attain maturity of fruits from flower bud emergence was lowest (141.5 days) in plants pruned on 1st May (T1). Average number of hermaphrodite flowers (96.09) male flowers (96.70) and total number of ((192.79) were highest in T12 (pruned on 15th October) and plants under this treatment also recorded the highest fruit set (58.44%), fruit retention (92.01%), average number of fruits per plant per month (51.55) and number of fruits per plant per year (360.85). These values were found to be the lowest in plants pruned in May (T1 and T2). Plants pruned on 1st May (T1) recorded the highest values of fruit weight (168.33g), volume of fruit (184.83cc) and fruit length (9.21cm) while thinnest peel (2.95mm) and the highest pulp-peel ratio were recorded in T12 (pruned on 15th October). Among the treatments, T12 (pruned on 15th October) was found to be efficient in terms of quality like highest juice content (35.66 %), TSS (6.330Brix) and ascorbic acid (37.95 mg/100ml) contents. From the present investigation, it was evident that mature fruits could be harvested from November onwards from the plants pruned during May-June. Though total production was lower in these plants as compared to the plants pruned during October (recommended practice) but because of higher prices per fruit during lean period (Nov-Feb), the benefit: cost ratio was also higher than the plants pruned during October from which fruits were harvested from April onwards.

(2023) Sharma, Antara; Kotoky, Utpal
A field investigation was carried out during the period 2022-23 to assess the effect of varieties and nutrient level on growth characters, physiological parameters, leaf and soil nutrient status of apple (Malus pumila) in the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat. The experiment was laid out in Factorial Randomized Block Design with four replications considering three low-chilling apple varieties viz. V1 (HRMN-99), V2 (Dorsett Golden) and V3 (Anna) and five different nutrient levels viz. N1 [FYM 5 kg/plant (Control)], N2 (5 kg FYM+ 50 g urea+ 70g SSP+ 40 g MOP/plant), N3 (5 kg FYM+ 100 g urea+ 140g SSP+ 80 g MOP/plant), N4 (5 kg FYM+ 150 g urea+ 210g SSP+ 120 g MOP/plant) and N5 (5 kg FYM+ 200 g urea+ 280g SSP+ 160 g MOP/plant). The findings of the experiment revealed that the variety V1 exhibited the highest significant plant height (52.67 cm, 101.05 cm, 124.43 cm and 179.76 cm), stem girth (3.91 cm, 5.08 cm, 6.35 cm and 9.91 cm), leaf area (35.33 cm2, 50.24 cm2, 56.18 cm2 and 63.34 cm2) and leaf area index (1.33, 2.04, 2.20 and 2.42) at 90, 180, 270 and 360 DAP respectively. However, the highest number of branches (6.05, 8.75, 10.20 and 14.65) were observed in V2 which was statistically at par with the variety V1. Amongst various nutrient levels, N4 showed the superior performance in terms of plant height (56.78 cm, 115.26 cm, 143.75 cm and 192.03 cm), stem girth (4.51 cm, 6.04 cm, 7.33 cm and 11.30 cm), number of branches (7.00, 10.25, 11.83 and 17.25), leaf area (42.66 cm2, 56.53 cm2, 63.27 cm2 and 69.38 cm2) and leaf area index (1.53, 2.28, 2.44 and 2.61) at 90, 180, 270 and 360 DAP respectively. Among the physiological parameters, the leaf relative water content (63.46% and 71.90%) in variety V1 and (68.81% and 81.77%) under nutrient level N4 were observed to be significantly highest both at 30 and 45 DAT respectively. The total leaf chlorophyll content showed similar trends with the highest (1.58 mg/g fresh wt. and 1.68 mg/g fresh wt. of leaf sample) in variety V1 and (1.72 mg/g fresh wt. and 1.81 mg/g fresh wt. of leaf sample) under nutrient level N4 at 30 and 45 DAT respectively. The leaf nutrient status with respect to leaf N (2.39% and 2.27%), leaf P (0.25% and 0.22%), leaf K (1.75% and 1.71%), leaf Ca (1.45% and 1.65%) and leaf Mg (0.32% and 0.39%) were found to be highest in the variety V1 at 30 and 45 DAT respectively. The nutrient level N4 exhibited the highest significant leaf N (2.66% and 2.50%), leaf P (0.29% and 0.25%) and leaf K (1.84% and 1.83%) at 30 and 45 DAT respectively. However, the nutrient level N3 was found to be superior in terms of leaf Ca and Mg concentrations which was statistically par with N4 at both the studied intervals after application of respective treatments. Analysis of the soil nutrient status after the experiment resulted in significantly highest organic carbon content, available N, P205 and K20 in variety V3 and nutrient level N5 while the highest exchangeable Ca and Mg were observed under the influence of variety V1 and nutrient level N4. Interaction of varieties and nutrient levels also recorded significant effect for most of the growth parameters with the highest obtained under the combination of variety V1 and nutrient level N4. Therefore, based on the results of the present investigation, the low-chilling variety HRMN-99 at nutrient level of 5 kg FYM+ 150 g urea+ 210g SSP+ 120 g MOP/plant can be recommended for apple cultivation under Assam condition in the first year of its plantation.

In the present study, the inorganic treatment T15 was found to perform best in terms of growth and yield. Significantly the highest plant height (66.02 cm and 94.00 cm at 45 DAS and at 60 DAS, respectively), internodal length (8.73 cm at 60 DAS), length of leaf (17.98 and 20.25 at 45 DAS and 60 DAS respectively), breadth of leaf (20.23 and 22.74 at 45 DAS and 60 DAS respectively) and number of functional leaves per plant (12.71 and 16.52 at 45 DAS and 60 DAS respectively) were recorded in T15. Among organic treatments, the highest plant height (65.70 cm and 90.70 cm at 45 and 60 DAS respectively), internodal length (7.86 cm at 60 DAS), length of leaf (17.84 and 19.54 at 45 DAS and 60 DAS respectively), breadth of leaf (20.04 cm and 22.04 cm at 45 DAS and 60 DAS respectively) and number of functional leaves per plant (12.16 and 16.06 at 45 DAS and 60 DAS respectively) were recorded in treatment T1. All the physiological parameters viz. area of a leaf, leaf area per plant, leaf area index, total leaf chlorophyll content, chlorophyll stability index and relative leaf water content were recorded significantly highest in inorganic treatment (T15). Among the organic treatments these parameters were found best in T1 whereas the lowest was recorded in T16 (Control). The minimum days for appearance of the first flower (30.12 days) and days to first harvest (37.12 days) were recorded in treatment T11 and maximum harvest duration was recorded in T15 (41.43 days). Again, the maximum number of fruits per plant (18.99), fruit length (14.10 cm), fruit girth (6.55 cm), fruit volume (18.42 cc), the weight of individual fruit (15.71 g), fruit yield per plant (0.29 kg) and yield per hectare were recorded in treatment T1. However, the fruit yield per hectare was significantly highest in inorganic treatment T15 (14.12 t/ha). Among all the treatments the highest vitamin A (375.06 I.U) and vitamin C (29.00 mg/100g) were recorded in organic treatment T5 and minimum fiber content was recorded in T12 (9.76 %). Minor incidences of pests and diseases were observed and it was controlled effectively at the initial stage by applying proper organic fungicide and insecticide. Considering the highest B:C ratio (2.53:1) and with superior morphophysiological attributes among the organic treatments in T1, it could be advised to the grower of this region to apply FYM @20t/ha in Okra to get a good crop harvest with quality fruit.
