Field experiments were conducted to evaluate the efficacy of various insecticides against mustard aphid, Lipaphis erysimi on mustard crop during rabi seasons 2020-21 and 2021-22. The results on the field efficacy revealed that performance-wise treatments were in the order of imidacloprid 17.8 SL > thiamethoxam 25%WG> acetamiprid 20%SP > dimethoate 30%EC > malathion 50%EC > fipronil 5%EC > profenofos 50%EC > buprofezin 25%EC. The least population (5.40/plant) of aphid was obtained with application of imidacloprid 17.8% SL at 7 DAS and (6.67/plant) at 10 DAS during 2020-21 and 2021-22, respectively. The same trend was observed till 28th day in comparison to rest of the treatments and untreated control. Significant reduction in population was observed with imidacloprid 17.8 SL @ 27.0 gm a.i./ha followed by thiamethoxam 25%WG @ 25 gm a.i./ha and dimethoate 30%EC @ 200 gm a.i./ha. Imidacloprid and thiamethoxam were significantly superior to other treatments. The maximum yield was obtained with imidacloprid (17.99 and 18.22 q/ha) followed by thiamethoxam (16.62 and 17.37q/ha) during 2020-21 and 2021-22, respectively.

Effect of row ratios and organic nutrient management on productivity and economics of Indian mustard (Brassica juncea) + chickpea (Cicer arietinum) intercropping system

A field experiment was conducted during winter (rabi) seasons of 2021–22 and 2022–23 at the research farm of Indian Agricultural Research Institute, New Delhi to find out the suitable cropping system with optimum row ratio and nutrient management practice in Indian mustard [Brassica juncea (L.) Czern.] + chickpea (Cicer arietinum L.) intercropping system. Cropping systems i.e. mustard sole; chickpea sole; mustard + chickpea 2:5; mustard + chickpea 5:2 was taken as main plots. Nutrient management practices i.e. control; 60 kg Nitrogen/ha; 20 kg Nitrogen through farmyard manure + leaf manure; 20 kg Nitrogen through farmyard manure + leaf manure + microbial consortia were taken as sub-plots to attain a higher degree of precision. It was observed that though the crop yields of individual crops of mustard and chickpea were the highest in sole crop, but yield of intercropping system in terms of mustard equivalent yield was found to be the highest for mustard + chickpea 5:2 row ratio. Yields of both mustard and chickpea were observed to be the highest in the plots treated with combination of organic manures and microbial consortia i.e. 20 kg nitrogen through farmyard manure + leaf manure @4 t/ha + microbial consortia. Highest gross returns, net returns and benefit-cost ratio were found in mustard + chickpea 5:2 row ratio. Analysis of intercropping indices revealed the highest intercropping advantage in mustard + chickpea 5:2 row ratio when treated with organic manures and microbial consortia. Intercropping systems had land equivalent ratio more than unity, depicting advantage. Aggressivity values showed mustard crop was dominant over chickpea.

Impact of Sulphur Nanoparticles on Growth and Biological Yield of Groundnut-Mustard Crop Sequence Under Sandy Loam Soils of Central Gujarat

In the present era of farming, the farmers were not using the secondary fertilizers for supplementing the sulphur nutrient and groundnut and mustard crops require the higher amount of sulphur. While, the traditional sulphur fertilizers have very low nutrient use utilization efficiency, moreover nano fertilizers have high nutrient use efficiency. So, the present experiment was conducted with using the different sources of sulphur. The existing experiment was conducted at Anand Agricultural university, Anand, in 2021-22 using completely randomized design with 11 treatments replication 4 times. The results reveal that the significantly higher plant height at 30 DAS was registered with the application of RDF + sulphur nanoparticles @ 4 mg S/kg (T10), than rest of the treatments. The significantly higher plant height, branches/plant and biological yield of groundnut-mustard cropping sequence was obtained with the fertigation of RDF + sulphur nanoparticles @ 3 mg S/kg soil, 50% at basal & 50% at 30 DAS (T9). It can be concluded that application of 3 mg S/kg soil, 50% at basal & 50% at 30 DAS can be an optimum dose of sulphur in pot experiment through fertigation under sulphur deficient soil.

Epibrassinolide application improves Brassica juncea L. performance by augmenting gas exchange markers, stomatal behavior, cellular viability, enzymatic activities and yield attributes

Epibrassinolide (EBL) is an emerging plant growth regulator of the brassinosteroids group that has the potential to modulate various morpho-physiological processes in plants. Therefore, due to its key role in boosting plant functioning mechanisms, it is widely used in agriculture to enhance crop growth and yield. The present research work was planned to investigate the role of exogenously applied EBL on the mustard crop by assessing morphological, physiochemical, and yield features. This randomized pot experiment contains three mustard cultivars i.e., Rohini (Roh), Chutki (Chk), and Nath Sona (Nas) and various graded levels of EBL, 0 (Control), 10−8 M, 10−7 M, 10−6 M, 10−5 M, and 10−4 M. EBL was applied twice by giving first spray at 50 days after sowing (DAS) and the second at 70 DAS. Evaluation of plants was done at 90 DAS to study phenological traits, gas exchange attributes, non-enzymatic antioxidant activities, and microscopical parameters. The yield and quality features were studied at 120 DAS. The results revealed that treatment of 10−6 M EBL proved effective and increased fresh weight by 17.76 %, 19.11 %, and 19.34 %, chlorophyll content by 26.50 %, 26.59 %, and 25.86 %, net photosynthetic rate by 45.67 %, 57.88 % and 49.76 %, protein content by 66.98 %, 68.62 % and 69.47 %, proline content by 25.70 %, 24.05 % and 21.87 %, ascorbate content by 94.91 %, 89.99 % and 87.43 %, carbonic anhydrase activity by 32.43 %, 30.84 % and 29.93 %, seed yield by 44.85 %, 51.36 %, and 57 % and oil yield by 68.75 %, 72.71 % and 74.34 % in cultivars Nas, Roh, and Chk respectively over the control plants. Moreover, 10−6 M EBL supplementation significantly improved stomatal aperture width and root cell longevity. Cultivar Nas, followed by cultivars Roh and Chk, showed better responses on nearly all characters studied. The effect of EBL treatment in terms of enhancing the performance of the crop being in the order of 10−6 M > 10−7 M > 10−8 M > 10−5 M > 10−4 M. It may be concluded that among sprayed EBL levels, two sprays of 10−6 M EBL proved efficacious in improving the phenotypic, physiochemical, and yield traits of mustard cultivars.

The lower available nitrogen, phosphorus, potassium, sulphur, ammonical and nitrate nitrogen were recorded under the treatment of 75 % RDF.

Effect of Rate and Method of Zinc and Boron Application on the Yield Performance of Mustard

Zinc (Zn) and boron (B) deficiency are widespread nutritional disorders in crop plants, including mustard. However, Zn-B interaction on the performance of mustard crops is not well documented. A field experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, during November 2021 to February 2022 to evaluate the effect of rate and method of Zn and B application on the yield performance of mustard (BARI Sarisha-18). The experiment comprised nine doses of Zn & B as a basal and foliar application viz., recommended Zn (2 kg ha-1) and B (2 kg ha-1) as basal, 75% Zn and B as basal + 25% Zn and B foliar spray at pre- flowering stage, 50% Zn and B as basal + 50% Zn and B foliar spray, 100% Zn and B as basal + 25% Zn and B foliar spray, 100% Zn and B as basal + 25% Zn foliar spray, 100% Zn and B as basal + 25% B foliar spray, 100% Zn as basal (without B), 100% B as basal (without Zn), control (no Zn and B). The experiment was laid out in a Randomized Complete Block Design with three replications. The result revealed that yield was influenced significantly by the rate and method of Zn and B application. The highest plant height (140.57 cm), the maximum number of branches plant-1 (5.84), maximum number of effective pods plant-1 (87.57), maximum number of seeds pod-1(31.53), the highest seed yield (1.85 t ha-1) and the highest stover yield (4.47 t ha-1) were obtained from 100% Zn and B as basal + 25% Zn as foliar. The lowest number of seeds pod -1 (27.20), 1000-seed weight (3.35 g), seed yield (1.33 t ha-1) and stover yield (3.35 t ha-1) were obtained from the control treatment. The result showed that the seed yield of mustard increased with increasing levels of both Zn and B as basal 100% with only Zn 25% as foliar, respectively. Therefore, 100% zinc combined with 100% B as basal and 25% Zn foliar application may be recommended for higher seed yield of mustard (cv. BARI Sarisha-18).

 Place and Duration of Study: The present study was conducted by ICAR-IIVR - Krishi Vigyan Kendra, Bhadohi on mustard at farmer’s field in different blocks of Bhadohi district under cluster front line demonstration during the period 2016-17 to 2020-21.
 Methodology: From 2016-17 through 2020-21, 374 demonstrations were carried out on farmer fields totaling 153 hectares under cluster front line demonstration, with farmer practice acting as the comparison control. KVK scientists collected yield, production expenses, and return data from farmers' practice plots (control plots) and front-line demonstration plots. Finally, the extension gap, technology gap, and technology index were calculated using the methods describe in Samui et al. [1].
 Results: The five-year study's findings show that the demonstration plots' average annual yield was 24.20 q/ha in compared to the traditional agricultural plots' average annual yield of 17.26 q/ha. This higher yield of 4.85 q/ha and the 40.12% rise in mustard productivity over the previous five years may be enough to meet the state's current needs for oilseeds. The five-year averages for the technology gap, extension gap, and technology index were found to be 5.8 q/ha, 6.8 q/ha, and 19.35%, respectively. The finding unequivocally shows that CFLDs have advantages over conventional practices. The technology gap, extension gap, and technology index five-year averages were determined to be 5.8 q/ha, 6.8 q/ha, and 19.35%, respectively. Under the demonstration plot, the Benefit Cost Ratio was shown to be greatest (3.0) during the study year 2017-18 and lowest (2.24) during the study year 2019-20, but it averaged 2.65 during the five-year study period. As a result, positive benefit-cost ratios established the economic sustainability of the interventions and persuaded farmers in the Uttar Pradesh area of Bhadohi of their worth.
 Conclusion: According to the findings of the five-year study, the demonstration plots' pooled five-year average production was 24.20 q/ha as opposed to the traditional farmer practices plots' 17.26 q/ha. This enhanced yield of 4.85 q/ha and the 40.12% rise in mustard productivity over the previous five years, may be helpful meet to the state's current needs for oilseeds. The finding unequivocally shows that CFLDs have advantages over conventional practices. During the years of investigation, it was shown that the benefit-cost ratio was higher when agricultural practices were demonstrated. According to the result it is concluded that the yield and net profit may be increase using HYV RH-749 with the recommended packages of practices in mustard crop.

COMPARATIVE ASSESSMENT OF GENETIC DIVERSITY BETWEEN BRASSICA NAPUS AND BRASSICA JUNCEA BASED ON PHENOTYPIC TRAITS

Rapeseed and mustard crops’ extensive promotion for crop diversification and their potential to favorably respond to breeding programs depends on their existing nature and the magnitude of genetic variability. Therefore, the progressive research sought to estimate the genetic diversity of 40 genotypes of Brassica napus (20) and Brassica juncea (20) based on phenotypic characters. The material, grown in randomized complete block design, had three replications during winter 2020– 2021. The mean square from analysis of variance demonstrated significant differences for all the parameters among examined varieties, indicating that utilized material contained sufficient genetic variability. Regarding average performance, two mustard genotypes, Dhoom-I and Anmol Raya, performed better for seed yield plant-1 and can undergo assessment in upcoming breeding programs for enhancing seed yield. Meanwhile, high heritability occurred in oil content, silique length, 1000-seed index weight, and plant height. Diversity analysis, cluster mean, and total divergence contribution revealed maximum differences for various traits and possessed noteworthy sources for future breeding programs. The magnitude of cluster distance indicated that cluster VI comprised two mustard genotypes (Early Raya and Sindh Raya) and cluster IV consisted of three rapeseed genotypes (Rohi Sarson, hyola-401, and Kn-277), demonstrating that maximum distance is more diverse and helpful for upcoming heterotic recombination. Comparing genetic variation between rapeseed and mustard genotypes showed that rapeseed genotypes displayed more genetic variability in the first three components of PCA than its counterpart, yet expressing that mustard genotypes also have enormous valuable genetic resources. Similarly, genotypes Rohi Sarson, hyola-401, and Kn-277 resulted in the highest genotypic scores in three-dimensional graphs; hence, these genotypes are more diverse and can benefit future hybridization programs.

Monitoring Studies of Arthropod Complex Fauna Associated with Rapeseed- Mustard Crop Grown in Kashmir Himalayas

Kashmir has quietly undergone a yellow revolution as thousands of hectares of land have been brought under mustard cultivation to double the farmers' income. Earlier, most of the land in Kashmir was used only for growing a single crop -- paddy in most areas but now farmers are rotating crops in Kharif and Rabi seasons just like in other parts of the country. There is still many challlanges which are hurdle in high production goal. Insect biodiversity is associated with the quantity and type of host plants available, environmental factors, and their physiological state. Arthropod complex of mustard was studied and about eight species of insects-pests at Mountain Research centre for field crops (MRCFC) during Rabi 2020 -21 was recorded. It has been observed that the mustard aphid, Lipaphis erysimi Kalt., persists constantly in a sizable population and causes substantial crop damage from the blossoming to the maturity stage. Phyllotreta cruciferae Goeze (flea beetle) occurred at the seedling stage, and Carpocoris sp. (shield bug) caused little harm to the crop from the seedling to the maturity stage. Leaves have been only infested by cabbage aphid, Brevicoryne brassicae, mustard aphid, Lipaphis erysimi (Kalt.), and mustard leaf miner, Chromatomyia horticola, and they been detected in sporadic, low-population occurrences. Among them, Brevicoryne brassicae is found at flowering stage. Pieris brassicae, the cabbage butterfly, occurs sporadically and with high abundance. The status of all eight insect-pests on Brassica species was observed as minor with irregular occurrence while L. erysimi as a regular key pest.six Insect pollinators were recorded during the bloom period of the crop.
