AbstractThe study was carried out to evaluate thirty varieties of ber which were screened in vivo conditions for their resistance to fruit fly for two consecutive years. Investigation revealed that none of the ber varieties were identified as completely free from the attack of fruit fly. Based on the pool mean of fruitfly per cent damage,the varieties likeTikadi, Umran and Ilaichi had fruits infestation less than 10 per cent, therefore, categorized as highly resistant; varieties Baghwadi, Hussain rejo, Jogia, Kali, Kathaphal, Kheera, Sukhawani and Tabes taso possessed mean fruit infestation from 11-20%, therefore, categorized as resistant, varieties Akhrota, Ashapuri-2, Chandni supari, Chhuhara, Chonchal, Darakhi, Gola, Gutka, Kishmish, Lakhan, Mehroon, Morchia, Nilgiri, Noki, Ponda, Sev and Thornless had fruit infestation between 21-50%, therefore, categorized as moderately resistant; variety Kaithli had fruit infestation above 51%, categorized as susceptible.
AbstractThe field efficacy of novel fungicides against purple blotch disease in onion was carried out at Krishi Vigyan Kendra, Almora, Uttarakhand during rabi eason of the year 2021-22 and 2022-23 to find out the promising fungicide for management of this disease. The observations recorded on various parameters namely per cent disease index (PDI), yield, gross income, net income, benefit cost ratio etc. revealed that treatment-T1 (Azoxystrobin+Difenconazole) @1ml/l of water was found to be most effective with PDI of 3.77% in 2021-22 and 2.86% during 2022-23 at 80DAT. The maximum bulb yield harvested under T1 was 299.56 q/ha during 2021-22. The net income and B.C. ratio recorded to be Rs. 3,22,002/ha and 2.72 in 2021-22, respectively. Almost same trend was observed during 2022-23 in T1. The treatment-T2 (Difenconazole @ 0.5ml/l of water) had also significant impact on management of purple blotch in onion. It is pertinent to mention that T1 was significantly superior over other treatments including T2 but it was observed that very slight variation was recorded between T1 and T2 in all parameters under investigation. The data taken on incidence of disease in the control (T3) indicated the severity of the disease under unprotected condition in rabi onion.
AbstractThe present investigation was conducted during rabi season of the year 2019-20 at Research Farm of Udai Pratap College, Bhojubeer, Varanasi (U.P.).The eight treatments viz., T1 - Control, T2 -Farmyard manure ( FYM ) @ 20 t/ha, T3 - Vermicompost @ 5 t/ha, T4 -Neem cake @ 5 t/ha, T5 - Biofertilizer (Azotobactor + PSB ) each @ 5 kg/ha, T6 - Farmyard manure + biofertilizer, T7 - Vermicompost + biofertilizer , T8 -Neem Cake + biofertilizer, were evaluated in randomized block design with three replications. The experimental findings revealed that the treatment (T7) showed a better response to plant growth, yield and quality attributes. However, a maximum yield 272.50 q/ha was obtained with the application of T7 (Vermicompost + biofertilizer) followed by T8 ( Neem cake + biofertilizer). Based on economic analysis maximum cost-benefit ratio 1: 2.91 was obtained in T8 and found most beneficial for the cultivation of cauliflower under Varanasi region.
AbstractSarpgandha (Rauwolfia serpentina L.) is an important medicinal plant which is is damaged by several fungal diseases, including Cercospora leaf spot disease which is one of the major challenges. An experiment was designed to evaluate the efficacy of some botanical biofungicides against the Cercospora leaf spot disease of Sarpgandha. A minimum disease incidence of 23.58 per cent was recorded in Tulsi (leaf extract) @ 5 per cent followed by neem (leaf extract) @ 5per cent, garlic bulb extract @ 5 percent, turmeric rhizome extract @ 5 per cent and lemongrass @ 5 per cent. A maximum reduction of 63.54 per cent in disease incidence was recorded in tulsi (leaf extract) @ 5 per cent were significantly reduced disease incidence.
AbstractThe present study was carried out on fruit bagging, reflective mulch and foliar potassium spray on coloration and postharvest life of apple cv. Fuji Zehn Aztec in high-density Apple block at Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar, Srinagar. Treatments consisted of fruit bagging done at two time periods (4 and 6 weeks after petal fall), reflective mulch at two different widths (100cm and 75 cm), potassium sulphte spray at two concentrations (0.50% and 0.75%) and all 4 combinations of reflective mulch and potassium sulphate spray, constituting total 11 treatments. The study revealed that improvements with respect to fruit color and anthocyanin content were observed by all the treatments over control, the treatment consisting of potassium sulphate spray@0.75% + polyethylene reflective mulch (100 cm) proved to be most appreciating wherein figures regarding fruit color (22.93 a*, 37.36 h0) and anthocyanin content (12.09 mg/100g) was above the values as recorded under other treatments. Further, there was no significant effect of different treatments on storability as physiological loss in weight of fruits was not affected significantly by any treatment. However, the treatment potassium sulphate spray@0.75% + polyethylene reflective mulch (100cm) significantly increased the TSS (18.80, 18.95, 19.12, 19.32%) during storage at 0, 10, 20 and 30 days respectively at ambient conditions as compared to other treatments, while the maximum fruit firmness (11.78, 11.70, 11.52, 10.95 kg/cm2) was retained by treatment control. The study indicated that Fuji apple showed positive responses to the application of fruit bagging, reflective mulch, and foliar potassium spray in increasing fruit color, which is otherwise the main problem in Fuji apples.
