In this research work, we attempted to know the positive response of putrescine on plant growth and flowering of annual flower gypsophila. Putrescine is important because it has been shown that exogenous treatment can enhance the production or accumulation of bioactive chemicals that show a positive impact on plant growth and development. Significant results were obtained in various growth and flowering parameters of annual gypsophila due to foliar treatment with putrescine. Maximum plant height, maximum plant spread, maximum number of leaves per plant, maximum number of primary branches and secondary branches per plant at 60 DAT and 90 DAT as well as maximum number of flower clusters per branch and maximum number of flower clusters per plant was recorded from 1.50 mmol of putrescine application.

This experiment suggests that the utilization of the greengram variety IPM 02-3 is advantageous due to its superiority in terms of performance and adaptability over other varieties investigated. Additionally, application of 50 kg/ha P2O5 and K2O demonstrates comparable performance and profitability to application of 60 kg/ha P2O5 and K2O, making it an economically favourable option. Soil fertility analysis revealed P and K's role in enhancing nutrient dynamics. The relation between soil nutrient levels and greengram yield underscores the multifaceted relationship. In summary, genetic factors, coupled with optimal nutrient management, synergistically affect the growth and yield of greengram.

There is a dearth of rootstock studies on how salinity stress imparts tolerance to the scion cultivar in citrus [Citrus sinensis (L.) Osbeck]. The impact of sodium chloride on sweet orange cv. Pusa Sharad (PS) grafted on 11 different rootstocks i.e. Jatti khatti (JK), X–639 (X9), CRH–12 (C12), NRCC–1 (N1), NRCC–2 (N2), NRCC–3 (N3), NRCC–4 (N4), NRCC–5 (N5), Troyer citrange (TC), CRH–47 (C47) and Cleopatra mandarin (CM) was evaluated at the nursery unit of ICAR-Indian Agricultural Research Institute, New Delhi, during 2019–22. Irrigation water containing 30 and 60 mM of sodium chloride (NaCl) was applied to scion/rootstock combinations in comparison to control (without NaCl) till the onset of salt injury symptoms i.e. 42 days. Under salinity stress, the PS scion grafted onto CM, X9, C47, N1, and N3 rootstocks exhibited minimum reduction in the scion height, leaf area ratio, root to shoot ratio, total chlorophyll content, total carotenoid content, transpiration rate, photosynthesis rate, internal CO2 concentration and stomatal conductance as compared to PS scions grafted onto JK, C12, N2, N4, N5, and TC rootstocks under 60 mM NaCl stress. Results showed that specific rootstock can enhance salt-tolerance potential by increasing pigment content and strengthening the photosystem. PS scions grafted onto CM, C47, X9, N1, and N3 demonstrated greater NaCl tolerance compared to those grafted onto JK, C12, N2, N4, N5, and TC and hence recommended for areas having salinity level up to 60 mM.

Vegetable farming plays an important role in the country's agricultural economy. Between the actual harvested yield and the potential yield of vegetable crops in Haryana state, there is a notable discrepancy. As a result, potential has yet to be fully realized. Numerous other industries, like processing, seeds industry, fertilizer, pesticides and farm machinery industry are supported by vegetables. The present study was carried out to analyze the trend in area, production and productivity of overall vegetables in Haryana and India. Area, production and productivity of overall vegetables shows a significant increase and positive trend from 1990–91 to 2020–21 with a compound annual growth rate (CAGR) of 7.00, 8.13 and 1.06% in Haryana and 3.18, 4.65 and 1.43% in India. Potato, onion, tomato, radish, carrot, cauliflower and bottle gourd are the major vegetables grown, amongst which highest production, viz. 0.81 and 54.75 million tonnes was recorded under potato during 2020–21 in Haryana and India, respectively.

Drumstick (Moringa oleifera L.) is a tropical plant with wider adaptability to drought and different agro-climatic conditions. The different plant parts including leaves, fruits, flowers and immature pods are used throughout the world for various purposes due to their high nutritive value. The 34 genetic resources of drumstick along with Thar Harsha variety were investigated in this study during 2019–2021 on quality parameters at ICAR-Central Horticultural Experiment Station, Panchmahals, Vadodara, Gujarat. Results showed that the percentage of dry matter and moisture content ranged from 10.86 to 17.98 and 83.08 to 89.14 (pod), 8.16 to 14.80 and 83.40 to 93.38 (pulp), 16.00 to 22.80 and 72.20 to 84.00 (skin) and 24.62 to 30.54 and 69.46 to 75.38 (leaves), respectively. The total phenolic (TP) content (mg GAE/100 g) in pod (26.36– 39.90), pulp (151.54–232.70), rind (73.37–169.06) and leaves (448.21–970.16) were recorded. The pod, pulp and leaf of CHES D-40 accession recorded the highest TP content. While, the rind of CHES D-42 accession recorded the maximum TP content. Similarly, leaves and pods of CHES D-40 showed the highest vitamin C. In 2, 2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) assay, the antioxidant activity of M. oleifera accessions leaves varied from 14.83 to 31.29 µmol TE/g. In all nutrient contents of the M. oleifera accession dry leaf powder was quantified with wide variation. The accession CHES D-40 recorded the highest N, K, Ca, S, and Fe in leaves, whereas, P and Cu in CHES D-42, Mg and Zn in CHES D-34 leaves. The protein varied from 21.58 to 29.87 g/100 g in leaves, while in pod, 13.00 to 18.00 g/100 g. These results revealed that the potentiality of M. oleifera leaves in context to antioxidants and nutrients can be included in diets to supplement our daily nutrient needs.

An experiment was conducted at Krishi Vigyan Kendra, Ferozepur, Punjab during rainy (kharif) seasons of 2018 and 2019 to study the effects of nitrogen levels and weed management in direct-seeded rice (Oryza sativa L.) (DSR). The results indicated that pendimethalin + bispyribac (W1) (5.25 and 2.95 m2) and oxadiargyl + bispyribac (W2) (6.05 and 3.95 m2) application reduced the density of narrow-leaved weeds (NLW) and broad-leaf weeds (BLW) followed by oxadiargyl + fenoxaprop (W3) (7.0 and 4.55 m2) during both the years. Application of W1 decreased the total weed biomass by 84–98.2%, respectively compared to weedy check (W5) (80.1 and 94.8 g/m2) in both years. Treatment W1 and W2 recorded at par values of grain and straw yield followed by W3. An increase (48.6–72.0%) in grain yield was registered with weed practices compared to weedy check in DSR. W1 and W2 significantly recorded higher N uptake in grain (61.45 and 60.85 kg/ha) and total (100.8 and 99.45 kg/ha) followed by W3 (53.85 and 90.35 kg/ha, respectively). The high infestation of BLW with W3 resulted in the lowest weed control efficiency (WCE) (46.2–53.9%) among the weed control practices. N at 120 and 150 kg/ha recorded the low density and biomass of NLW and BLW. Application of 120 and 150 kg N/ha enhanced the grain yield (4.89 and 5.25 t/ha) and net returns (55.1 and 60.5 × 103 ₹/ha) in both years. No N application recorded lowest N uptake in grain (87.71 kg/ha) and total (80.26 kg/ha) compared to 150 kg N/ha in both years. N levels at 120 and 150 kg/ha recorded higher values of water control efficiency (WCE). Based on the findings, it may be concluded that pendimethalin + bispyribac and oxadiargyl + bispyribac with N 120 kg/ha application can reduce weed flora diversity with higher grain yield of direct-seeded rice in Punjab.

From the experimental results, it is inferred that cotton crop responds well to the foliar nutrition with zinc and magnesium. Application of these nutrients through foliar spray might be the feasible option to control the yield barrier under rainfed condition. Further the study found that foliar spraying of MgSO4 1.0% along with 0.5% of ZnSO4 three times respectively at squaring, flowering and boll formation stages markedly improved the plant growth and seed cotton yield. Thus, these treatments may be recommended for enhancing the rainfed cotton yield but location specificity verification is required before recommendation.

The field experiment was conducted at G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during kharif season 2021–22 to evaluate the effects of tank-mix herbicides on weeds and maize (Zea mays L.) in order to determine the optimum dosage, application time and combinations of herbicides for maize. Based on the findings, it could be concluded that weed-free conditions are just as effective as atrazine applied with tembotrione or topramezone through sequential or tank mix application for reducing weeds effectively and increasing grain yield. Tank mix treatments of topramezone (25.2 g a.i./ha) and tembotrione (120 g a.i./ha) with reduced dose of atrazine (0.75 kg a.i./ha) should be employed by farmers since it not only removes weeds effectively but, also offers a better environment for maize to grow providing high profits for farmers. It also lowers the dose and expenses involved in manual weeding and spraying atrazine separately.
本试验于2021 - 2022年农作季在北阿坎德邦潘特纳格尔G.B.潘特农业技术大学进行，旨在评价罐式混合除草剂对杂草和玉米(Zea mays L.)的影响，以确定玉米除草剂的最佳用量、施用时间和组合。综上所述，在无杂草条件下，通过顺序或槽式混合施用阿特拉津与替博曲酮或topramezone，可以有效地减少杂草，提高粮食产量。农民应采用topramezone (25.2 g a.i./公顷)和tembotrione (120 g a.i./公顷)与减少剂量的阿特拉津(0.75 kg a.i./公顷)的罐式混合处理，因为它不仅有效地清除杂草，而且还为玉米生长提供了更好的环境，为农民提供了高利润。它还降低了人工除草和分别喷洒阿特拉津的剂量和费用。

It also lowers the dose and expenses involved in manual weeding and spraying atrazine separately.","PeriodicalId":13499,"journal":{"name":"Indian Journal of Agricultural Sciences","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135095354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For breeding programmes to be successful and for germplasm conservation, it is essential to characterize and analyze the genetic diversity of available germplasm. The present experiment was conducted at Molecular Biology and Genetic Engineering Laboratory of Uttarakhand Council for Biotechnology, Haldi, Uttarakhand during 2022 to study the molecular profile of 41 peach [Prunus persica (L.) Stokes] accessions using 23 polymorphic SSR markers. The number of alleles detected ranged from 3 to 8 with an average of 4.65 alleles per locus (Na) and a total of 107 alleles were amplified. The average effective number of alleles (Ne) were 2.89 per marker. The SSR marker MA015a produced maximum number of 8 alleles followed by BPPCT 015 and CPPCT14 which produced 7 alleles each. The polymorphic information content (PIC) varied between 0.317–0.836 with a mean value of 0.563. The observed heterozygosity examined was lower (Ho = 0.02) and the expected heterozygosity (He = 0.61) ranged between 0.34 to 0.85. The presence of a higher Shannon’s information index (I) of 1.17 indicates higher diversity in the given set of peach genotypes. Jaccard’s similarity coefficient ranging from 0.533 to 1, indicated a pair-wise relationship among the peach accessions. The cluster dendrogram partitioned the accessions into two main clusters. However, the total accessions were stratified into 3 groups (K=3) based on population structure analysis which was further confirmed by Principal Coordinate Analysis (PCoA). The information generated in the study may have great implications in molecular characterization, fingerprinting and documentation of accessions in the peach improvement programme.

The study suggests that in chickpea higher WCI, HEI and lower WI were noticed with the application of pendimethalin + imazethapyr 1.0 kg/ha as PE fb MW at 30 DAS. Although the application of topramezone @25.2 g/ha as PoE fb MW at 40 DAS (T5) resulted in higher WCI and lesser weed dry weight at both 60 and 90 DAS, the residual effect of this treatment was evident on the succeeding crops. Thus, standardization of the dose of topramezone for chickpea without any phytotoxic effect on the succeeding crops would pave the way for effective weed management in a cropping system mode.
