It has been observed that use of pesticides has been the main mode of control of pests and they are still in use on large scale as preventive and curative measures. The excessive and indiscriminate use of chemical pesticides and chemical fertilizers has resulted in serious environmental pollution, destruction of natural enemies, and development of resistance to these chemicals and residue hazards etc. Therefore, the needs to phase out the use of these chemicals are now taking momentum.

Soil physical and biological responses to rice establishment practices in rice-blackgram system
type: item
description: The field study, undertaken to assess the impact of different sowing dates and establishment methods in rice, along with weed management practices in blackgram, on the physical and biological properties of soil under rice blackgram system, was conducted using a split-split-plot design with four sowing dates as main plot treatments and rice establishment methods as sub plot treatments in kharif, and different weed management in conventionally sown blackgram as sub-sub plot treatments during rabi. The results revealed that early sowing and direct-seeded rice significantly improved soil physical properties such as bulk density, porosity and water stable aggregates due to better root proliferation and reduced puddling. Neither the date of sowing rice nor weed management practices in blackgram influenced bulk density and water stable aggregates values significantly. Moreover, biological properties such as microbial population, microbial biomass carbon and dehydrogenase activity showed a marked increase under the system involving early sowing i.e. one week before onset of monsoon and DSR and found statistically at par with NPTR.

Role of phosphate solubilizing bacteria in enhancing soil fertility and crop yields in arid environments – A Review
type: item
description: Phosphate solubilizing bacteria (PSB) are increasingly recognized as essential players in sustainable agriculture, particularly in arid and semi-arid regions where soil phosphorus (P) availability is often limited. These bacteria, which belong to a category of plant growth-promoting rhizobacteria are capable of converting insoluble phosphates into forms that plants can easily absorb. This process not only enhances nutrient uptake but also supports overall plant growth. Numerous studies have demonstrated the effectiveness of PSB in improving crop productivity in challenging environments such as the Andean Atacama Desert, Morocco, and parts of India. The combination of PSB application with organic and mineral fertilizers has been explored to address the adverse effects of soil salinization and calcification issues that are worsened by climate change. This review delves into the mechanisms by which PSB solubilize phosphate, factors influencing their activity, and the multitude of benefits they offer in arid regions, including enhanced phosphorus uptake, increased crop yields, improved plant development, enhanced water efficiency, and better drought resilience. The application of PSB biofertilizers are critical for boosting agricultural productivity in these arid landscapes. PSB present a viable solution for advancing sustainable agricultural practices in arid and semi-arid regions, though further research is necessary to fully capitalize on their potential.

Effects of benzyladenine and gibberellic acid on growth, flowering and Narcissus yield
type: item
description: The experiment carried out to study growth, flowering and yield parameters of Narcissus by using growth regulators, i.e., benzyladenine and gibberellic acid in different concentrations, revealed that application of BA (400 ppm) significantly increased length of leaf, width of leaf, width of scape, plant height, early opening of 1st flower and increased number of roots plant–1. BA at 300 ppm resulted in late senescence of 1st flower and diameter of bulb. Lower dose of BA i.e., 100 ppm significantly increased number of buds plant–1 and number of open flowers plant–1. Higher concentration of GA3 (200 ppm), significantly delayed opening of last floret, increased duration of flowering, number of bulbs hill–1, diameter of root, fresh and dry weight of roots. However, lower dose of GA3 (50 ppm) exhibited maximum weight of bulb and length of root.

Performance Evaluation of Self-Propelled Planter with Electronic Seed-Metering System
type: item
description: In Indian agriculture, seed placement is one of most crucial operations as it affects seed germination, growth and the productivity. Further, in narrow terraces of North Eastern Hilly Region of India, uses of tractor operated planters and other conventional plantersare not feasible. In addition, commercially available planters use mechanical metering which has many limitations including, skidding of the wheel, non-uniform seed rate, wastage of the seed and higher maintenance cost. Therefore, a lightweight self-propelled planter is required for timely operation with less drudgery in terraced terrain with a vertical interval more than 1 m. The seed plates powered by electric or hydraulic motors can effectively prevent the seed irregularities caused by wheel slippage on the ground and vibrations, thereby increasing the working speed and improving seeding accuracy. In order to deal such issues, an ergonomically designed planter with electronic seed metering system was developed. The performance results were analyzed and results with minimum value of missing index, multiple index, precision index and mean seed spacing as 5, 3.34, 16.23 per cent and 10.76 cm and highest value of quality of feed index of 91.67 per cent were recorded at groove size 5.45 mm, 25 per cent hopper fill level and running speed 1 km h-1 respectively.

Harnessing native antagonistic bio-agents for eco-friendly control of rice sheath rot caused by Sarocladium oryzae
type: item
description: Rice sheath rot, caused by Sarocladium oryzae, is a devastating disease threatening rice production worldwide, with yield losses ranging from 9.6 per cent to 85 per cent. Conventional reliance on synthetic fungicides has raised concerns about environmental sustainability and health safety, prompting the exploration of eco-friendly alternatives. This study investigates the in vitro efficacy of native antagonistic bio-agents, specifically Trichoderma spp. and Pseudomonas spp., against Sarocladium oryzae. Rhizospheric soil samples were collected to isolate and identify bio-agents, which were then tested using the dual culture method. Results revealed significant pathogen inhibition, with Trichoderma isolate Tr-1 achieving the highest inhibition rate (76.72%) among the Trichoderma isolates and in Pseudomonas isolates Ps-1 (61.21%) showed the significant inhibition. These findings highlight the potential of native bio-agents as sustainable, environmentally friendly alternatives to chemical fungicides, offering a promising strategy for integrated disease management in rice cultivation and advancing organic farming practices.

Seasonal incidence of insects on Solanum lycopersicum and their correlation with weather parameters
type: item
description: A field investigation was conducted to study the seasonal incidence of insect pests on tomato crops and their correlation with weather parameters. Eight insect species, including aphids, mealybugs, green plant hoppers, fruit flies, whiteflies, tomato fruit borer, leaf miner, and the parasitoid Cotesia glomerata, were recorded. Aphids, mealybugs, and hoppers peaked in early March, while fruit flies and whiteflies were most prevalent mid-March. The fruit borer and leaf miners reached peak populations in April, and C. glomerata was most active in the second week of March. Most insect populations showed a significant positive correlation with relative humidity, while correlations with temperature and sunshine were generally non-significant or negative. Leaf miners showed significant negative correlations with temperature and sunshine. The study highlights the strong influence of abiotic factors, especially humidity, on pest dynamics. Climate-resilient Integrated Pest Management (IPM) and biological control using C. glomerata are recommended for sustainable pest control

In-silico mining and characterisation of sweet genes in Mango (Mangifera indica L.)
type: item
description: The present study focuses on the insilico identiûcation of SWEET transporter coding genes in mango and its expression in leaf, root, unripe pulp, ripe pulp and jelly seed. Twelve different SWEET transcription factors genes/ transcripts (MiSWEET1, MiSWEET2, MiSWEET3, MiSWEET4, MiSWEET5, MiSWEET6, MiSWEET7, MiSWEET10, MiSWEET12, MiSWEET14, MiSWEET16, MiSWEET17) were mined in the fruit transcriptome data of mango jelly seed tissue. Motif 5 is the most conserved motif and seven amino acid residues in this motif are identical in nearly all SWEET members harbouring this motif. The proline (P, 5th), Leucine (L, 6th), Valine (V, 12th and 18th), Serine (S, 17th), Methionine (M, 21st), and Phenylalanine (F, 23rd) of motif 5 are largely conserved in this family, which might be important for sugar intercellular exchange in mango. To decipher the role of SWEET factors in this disorder, the expression analysis through semi-quantitative RT-PCR was analysed at root, leaf, unripe pulp, ripe pulp and jelly seed, revealing that these SWEET genes play developmental and ripening roles. Expression patterns of the SWEET genes during fruit development and ripening indicated that they may be involved in development and ripening by the ethylene signalling pathway. Our findings provide for further functional characterization of the SWEET family genes in mango and open the window of investigation of an important SWEET transcription factor family of genes and its role in mango fruit development and ripening.

Prevalence of root-knot nematode in tomato polyhouses: A soil sampling study from Delhi and nearby areas
type: item
description: The study, carried out across 14 polyhouses located in Delhi, Kurukshetra, Palwal, Panipat, and Sonipat, 0revealed prevalence of nematode infestations in soils of 78.6 per cent (11/14) of polyhouses. While two polyhouses surpassed the pathogenic threshold (2 J2/cc soil) at the preplanting stage, eight exceeded its threshold level during midplanting (up to 19.9 J2/cc), with all nine facilities assessed at the maturity stage surpassing it (up to 30.5 J2/cc). The highest nematode multiplication rates were observed in the Marinika cultivar (midplanting: 17.9; maturity: 37.8), particularly in soils lacking management interventions. Conversely, polyhouses implementing biocontrol agents (e.g., Trichoderma spp., Pseudomonas spp.) demonstrated reduced nematode proliferation, with the lowest rates recorded in Alawalpur I (6.3 and 10.6 at midplanting and maturity, respectively). Chemical treatments, such as Velum Prime, exhibited only transient suppressive effects. These findings emphasize the necessity of revising preplanting threshold criteria and implementing integrated nematode management (INM) approaches to ensure sustainable tomato production under protected cultivation systems

Advancing sustainable agriculture through remote sensing: spectral reflectance-based prediction of pearl millet growth and yield
type: item
description: Pearl millet (Pennisetum glaucum L.) is a crucial staple crop in arid and semi-arid regions, serving as a primary source of nutrition and income for millions. Given the increasing global emphasis on eco-friendly farming, integrating precision monitoring tools such as spectral reflectance indices into pearl millet production systems can significantly enhance sustainability. The present experiment was conducted to determine the relationship between spectral indices of various cultivars and their growth parameters and yield, demonstrating how non-invasive, spectral-based assessments can contribute to resource-efficient agriculture. The crop spectral reflectance, within wavelengths ranging from 320 nm to 1100 nm, was measured using a field-portable spectroradiometer between 1000 and 1200 hours across all treatment combinations. Growth and yield were found to be highly influenced by sowing directions, highlighting the importance of precision agronomy for maximizing resource efficiency. The findings reveal significant positive correlations between specific spectral indices (SR and NDVI) and growth parameters (LAI and dry matter) as well as yield. These relationships were analysed from emergence to maturity, with the highest correlation observed during the 50 per cent flowering to milking stage.

type: item
description: The field experiment on onion, conducted at Post Graduate Research Farm, Department of Soil Science, Mahatma Phule Krishi Vidyapeeth, Rahuri during the period of 2022-23, to ascertain the effect of foliar sprays of vermiwash (VW) on growth and yield of onion grown in Inceptiosl with seven treatment combinations consisting of RDF @ 75 and 100 per cent along with vermiwash foliar spray concentration @ 10, 20 and 30 per cent and one absolute control (water spray) replicated thrice in randomized block design. Results showed significantly higher number of leaves (10.80) to onion at 40 days after planting with the application of 100 per cent RDF along with two foliar sprays of vermiwash @ 20 per cent taken at 30 and 45 days after planting. Application of 100 per cent RDF with two foliar sprays of vermiwash @ 20 per cent concentration resulted significantly higher plant height (55.33 cm) at 30 days after planting, which was statistically at par with 75 per cent RDF + 30 per cent foliar spray of vermiwash (52.01 cm). Data revealed that, addition of 75 per cent RDF with two foliar sprays of vermiwash @ 30 per cent was significantly higher total soluble solids (15.46) in onion. Higher equatorial (67.08 mm) and polar diameter (66.66 mm) of onion was reported in the treatment receiveing 100 per cent RDF with two foliar sprays of vermiwash @ 20 per cent. It could be concluded from the data that the treatment receiveing 75 per cent RDF with two foliar sprays of vermiwash @ 20 per cent showed significantly higher onion yield and uptake of nitrogen, phosphorus, potassium, manganese and copper. However, application of 100 per cent RDF with foliar spray of vermiwash showed higher manganese and copper uptake by onion at harvest.

During the research, qualitative and quantitative standards of expected impacts on atmospheric air, sources and volumes of waste generation, their toxicity class standards for their further disposal were developed, and the impact of installed equipment on surface and groundwater was assessed. Draft standards for maximum permissible emissions (MPI) and production waste generation have been developed based on an inventory of their sources.

Bio-efficacy and viability of antagonistic yeast Pichia sp., in various solid formulations
type: item
description: The investigation, focused on exploiting the antigonistic potential of yeast Pichia spp. (strain YPS10) against fungal and bacterial pathogens, showed that Pichia spp. inhibited mycelial growth of Fusarium oxysporum f. sp. lini (57.70%) followed by Didymella naikii (50.00%). Xanthomonas campestris pv. vesicatoria, X. campestris pv. campestris and X. oryzae pv. oryzae exhibited significantly similar sensitivity to Pichia sp., with the zone of inhibition measuring from 17.60 to 19.00 mm. Formulations were developed using organic and inorganic carrier material after knowing their antagonistic nature. The results depict that the potentiality of different carriers in maintaining viability of Pichia sp., cells varied and their viability of cells lasts longer when the formulations were kept in refrigerators
