A rapid expansion in fresh water requirement for crops which require plenty amount of water along with industrial and household demand, is becoming a key concern. To overcome this constraint, work has been done on recycling and utilization of certain industrial effluent for agricultural use. In this sequence a study was conducted to analyse the effects of oil refinery on nitrate reductase activity and nitrogen contents in foliar parts of wheat variety PBW-343 about irrigation with refinery effluent at various dilutions. For this study, pot culture experiments of wheat crop variety PBW-343 were conducted in three replicates of every treatment. To analyse the response of nitrate reductase activity and nitrogen contents in wheat, five treatments with different concentrations of refinery effluent i.e., control, 25, 50, 75 and 100% were made with control water. It was observed that during the vegetative and post-vegetative growth phases, there was an increase in nitrate reductase activity and nitrogen contents in the foliar parts of the crop with an increase in concentration of effluent in irrigating water. The irrigating water with undiluted effluent had the least favourable impacts on nitrate reductase activity and nitrogen contents compared to the control water. The plants grown under seventy-five percent concentrated effluent had the most favourable impact on nitrate reductase activity and nitrogen contents in the foliar parts of this crop variety in all growth phases.

Black gram is a vital legume crop, but its yield is often limited by factors like nutrient deficiencies, pest and disease pressure, and abiotic stresses. Seaweed extracts may help mitigate these challenges by improving plant resilience and stress tolerance. The black gram was raised in Annamalai University Experimental Farm, Faculty of Agriculture, Annamalai Nagar, Tamil Nadu during February to April, 2021. The experiment consisted of seven treatments viz., 100 % RDF along with seed treatment and foliar application of seaweed extract (Sargassum sp. and Kappaphycus sp.) @ 5%, 10%, and 15% which was laid out in Randomized Block Design with three replications. Seed treatment and foliar application @ 5% seaweed extract (Sargassum sp.) + RDF excelled the other treatment in recording the higher yield, yield attributes viz., number of pods/plant, number of seeds/pod, test weight, seed yield and haulm yield. This research can contribute to developing eco-friendly and cost-effective alternatives to conventional agricultural practices, aligning with sustainable agriculture goals.

Green gram (Vigna radiata L. Wilczek), commonly referred to as mung bean or Vigna radiata, is an important pulse crop. The main causes of low pulse productivity were identified as the use of inferior seed, inappropriate crop management, and cultivation in marginal soils. It could be improved by creating low-cost seed production technology that is appropriate. It has been shown that seaweed extracts can improve crop development and increase nutrient uptake in both difficult and typical environmental situations. By reducing the frequency of fungal and insect attack, the use of seaweed extracts has led to encouraging gains in crop output, nutrient uptake, resilience to frost and stress, and seed germination. By keeping the aforesaid point of view, a study was conducted to know the effectiveness of seaweed extract on seed quality traits under invitro condition of Vigna radiata. The laboratory experiment aimed to evaluate the effect of seaweed extracts viz., Kappaphycus alvarezii and Gracilaria on the germination, growth and seed quality traits of green gram variety cv. VBN 2. The experiment was carried out in Department of Genetics and Plant Breeding, Annamalai University during the year 2022. The first step involved steeping the seeds in double-distilled water for six hours. Following their initial pre-soaking, the seeds were left to air dry at room temperature. Then, submerged the pre-soaked seeds in varying quantities of seaweed extract. Concentrations of 1.5%, 2.5%, 3%, 1% and 2% were utilized for Kappaphycus alvarezii and 2.5%, 5% and 10% were used for Gracilaria. For six hours, the various amounts of seaweed extract were soaked into the seeds. Paper towels were used to sow the treated seeds in order to collect data and observe the seedlings further. The results revealed that seeds soaked with Kappaphycus alvarezii at a concentration of 2.5% exhibited highest value for various seed quality parameters viz., germination percentage (81), root length (16.57), shoot length (19.64), fresh weight (38.58), dry weight (34.76), dry matter production (197.53), seedling vigour index (3452) and tetrazolium Test (80), compared to other treatments. Seeds soaked with Gracilaria didn’t show any variation among the different concentration treatments of Gracilaria, while minimum viability percentage was observed in control.

In India, rice (Oryza sativa L.) is a major cereal crop that accounts for 44.40 million hectares i.e. 30 per cent of the nation's total cultivated land. Nutrient management is one of the most important production restrictions for achieving a sustainable yield from a particular farming method. Ineffective nutrient management is a major problem in rice cultivation. Due to overuse of fertilizer there is loss of soil productivity and reduction in soil fertility. So, this research was conducted with a view of careful and effective use of chemical fertilizers, farm yard manure, vermicompost, press mud and poultry manure along with the foliar application of zinc sulphate, an integrated nutrient management system plays a critical role in balancing the soil fertility and plant nutrient supply to an optimal level. This approach results in an environmentally friendly and financially feasible solution for this issue and not only helps in supplementing requirements but also improves soil's physical, chemical, and biological properties. A field experiment was conducted in the Department of Agronomy, Faculty of Agriculture, Annamalai University, Tamil Nadu during June-September 2023 to assess the synergistic effects of integrated nutrient management along with foliar zinc sulphate on the growth of rice. The study evaluated nine treatments in a randomized block design. These treatments included varying levels of nitrogen supplemented with different sources of organic manures viz., farm yard manure, vermicompost, press mud and poultry manure and foliar application of zinc sulphate (ZnSO4). The results revealed that combining 75% nitrogen through urea and 25% nitrogen from vermicompost and 100% P and K along with foliar application of zinc sulphate (0.5%) at 25 and 50 days after transplanting (DAT) significantly improved all growth parameters viz., plant height, leaf area index, dry matter production, root length and root volume, number of tillers m-2, crop growth rate, and absolute growth rate of rice.

The present rate of rice production growth is far below the population growth rate. Therefore, the present deceleration trend in production and yield is a cause of concern and has to be reversed to meet the growing demand. Moreover, the profit margin in rice cultivation has eroded making rice cultivation unattractive. Therefore, new technologies are essential to increasing rice production in the country to meet the future demand of exploding population. Hence, there is an urgent need for enhancement of the productivity of rice by proper agronomic practices. One among them is foliar application of PGRs and NPK fertilizers for exploiting genetic potential of the rice crop. Therefore, a field experiment was conducted during 2022 at the Agronomy Experimental Farm, Faculty of Agriculture, Annamalai University, Tamil Nadu, India to study the effect of plant growth regulators and nutrients on growth and yield of transplanted rice under wetland ecosystem. The rice variety ADT - 43 was used as test variety. The experiment was laid out in randomized block design and replicated thrice with ten treatments includes foliar spray of plant growth regulators (Gibberellic acid, Triacontanol, Sodium para- nitrophenolate) (20 DAT) alone and in combination with macro nutrients like DAP, KCl and NPK (19:19:19) (40 and 50 DAT). The growth, yield parameters, grain and straw yield of rice viz., plant height (101.43 cm), number of tillers/hill (11.85), dry matter production (14847.67 kg/ha), number of panicles/m2 (372.30 m-2) number of filled grains/panicle (125.41), grain yield (6485.25 kg/ha) and straw yield (8890.34 kg/ha) were strikingly impressive by foliar application of gibberellic acid 40 % WSG @ 20 g/ha (20 DAT) along with 2 % DAP + 1 % KCl (40 and 50 DAT). The same trend was followed in harvest index (42.18 %). These combinations showed remarkable promise and seemed to hold greater potential as efficient systems.
