Field experiments were conducted to identify the best source of nutrients and bio-mulch for fruit yield, quality and soil properties of organic okra (Abelmoschus esculentus) at U B K V, Pundibari, West Bengal, India during February- May 2017-18. The experiment was laid out in Factorial RBD comprising of two factors, viz. organic nutrient sources (N) and bio-mulches (M) having four levels each. The findings of the experiment suggested that basal application of Azophos biofertilizer enriched vermicompost (5 t/ha) along with foliar spray of seaweed extract (2 ml/l) at 30, 40 and 50 days of sowing (N4) emerged as best treatment in terms of highest number of fruits (19.94/plant) and maximum yield (14.39 t/ha). Among the different bio-mulches, the vegetable legume plant residue mulch (M4) recorded highest number of fruits (20.79/plant), total fruit yield (14.79 t/ha), maximum ascorbic acid content (18.47 mg/100 g) and increased total chlorophyll content (46.99 mg/100 g). The interaction of N4M4 recorded highest number of fruit (22.88/ plant), fruit yield (348.08 gm/plant), total yield (16.68 t/ha) and the maximum total fruit chlorophyll content (51.60 mg/100 g). All the interaction of organic nutrient sources and bio-mulches showed increase in available N, P, K and organic carbon content in post harvest soil over the initial status. The study concluded that adoption of biofertilizer enriched vermicompost in combination with 3 times foliar spray of seaweed extract in standing crop with legume as mulch have significant positive impact on fruit yield, quality and soil properties of organic okra.
Field experiment was carried out at All India Coordinated Research Project on Vegetable Crops, OUAT, Bhubaneswar, Odisha, India in order to identify the superior F1 crosses for marketable fruit yield quality and resistance to bacterial wilt. All total 21 F1 crosses evolved from seven distinctly diverse local landraces of brinjal along with a hybrid check, Mahy Green were evaluated by adopting Randomized Block Design and replicated twice in rabi 2021-2022. Results revealed significant variations among various fruit quality attributes (TSS: 4.32 oBrix to 6.00 oBrix and ascorbic acid content of fruit: 5.10 mg100g-1 to 7.10 mg100g-1), incidence of bacterial wilt (30 DAT: 0.00% to 4.17%, 60 DAT: 0.00% to 12.50% and 90 DAT: 0.00% to 20.83%). Out of 21 crosses, nine cross showed immune reaction to bacterial wilt at 90 DAT. The marketable fruit yield plant-1 varied significantly from 1.00 kg to 1.99 kg. The F1 cross viz. BBSR-08-2 × Selection from BBSR-145-1(1.99 kg) recorded significantly highest fruit yield plant-1 followed by BBSR-08-2 × BBSR-10-25(1.87 kg) and BBSR-08-2 × BBSR-10-26 (1.81 kg). Thus, it may be concluded that, F1 crosses obtained from local landraces of brinjal viz., BBSR-08-2 × Selection from BBSR-145-1, BBSR-08-2 × BBSR-10-25 and BBSR-08-2 × BBSR-10-26 may be recommended for higher marketable fruit yield, fruit quality and over all resistance to bacterial wilt for higher profit. These local landraces may also be used for future brinjal improvement programme towards development varieties with higher fruit yield quality and resistance to bacterial wilt.
The experiment was conducted at Department of Vegetable Science, OUAT, Bhubaneswar from 2019-2021. Stored spine gourd seeds of six months old were used in this experiment. The seeds were first given various physical treatments (T1: control, T2: 48 hours soaking in water, T3: hot water treatment for 20 minutes + 48 hours soaking in water, T4: scarification by sand paper + 48 hours soaking in water, T5: removal of seed coat + 48 hours soaking in water) followed by chemical treatments (C1: GA3 100 ppm, C2: GA3 200 ppm, C3: KNO3 1%, C4: KNO3 2%, C5: Thiourea 1%, C6: Thiourea 2% & C7: control). The experiment was laid out in factorial CRD design with 35 treatment combinations replicated twice. The seeds were sown in plastic trays containing coco peat media. The effect of these treatments on number of days taken for initial germination, length of shoot, root, number of roots per seedling and percentage of seedling establishment in main field were recorded. From the data recorded, it was observed that among the physical treatments, T5 (removal of seed coat + 48 hours soaking in water), among the chemical treatments, C1 (GA3 100 ppm) and between the interactions, T5C1 (removal of seed coat + 48 hours soaking in water + GA3 100 ppm) took minimum number of days for initial germination with highest shoot and root length, maximum number of roots per seedling and highest establishment percentage in field. The lowest values were recorded in case of control. So, it can be concluded that removal of seed coat followed by 48 hour soaking in water and GA3 100 ppm treatment resulted early germination with desirable seedling traits and highest establishment percent in main field.
