Glutaminase Activity

A pot culture experiment was conducted at glass house of Department of Soil Science and Agricultural Chemistry, College of Agriculture, Rajendranagar, Hyderabad. The aim of the present experiment was to study the influence of crop cover and stage of crop growth on soil L- glutaminase activity in an Alfisol and Vertisol. The experiment was under taken with six crops viz., two cereals (Rice, Maize), two legumes (Groundnut, Greengram), one oilseed (Sunflower) and one vegetable (Bhendi) crop. The experiment was conducted in Completely Randomized Block design with three replications along with the uncropped control. The results obtained with regard to the effect of these crops on soil L-glutaminase activity showed that there was an increase in enzyme activity with age of the crop upto 60 DAS and it varied with crops grown. The increased enzyme activity (μg of NH4+ released g-1 soil 4h-1) varied from 5.56 to 12.17 for groundnut, 5.58 to 11.25 for greengram, 5.43 to 10.87 for sunflower, 5.48 to 8.61 for rice, 5.39 to 8.23 maize and 5.31 to 7.92 for bhendi in Vertisol. In Alfisol the L-glutaminase activity (μg of NH4+   released  g-1   soil  4h-1)  under  different  crop  cover  found  to  vary  from 6.72  to  13.59 (groundnut), 6.68 to 12.71 (greengram), 6.63 to 11.96 (sunflower), 6.61 to 10.25 (rice), 6.59 to 9.47 (maize), 6.62 to 9.26 (bhendi).  A close perusal of the data indicates that the L-glutaminase activity followed the sequence groundnut > greengram > sunflower > rice > maize > bhendi, in both Alfisol and Vertisol.

The present study was carried out during kharif season 2019-20 at the Research Farm, Department of Soil Science & Agricultural Chemistry, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh (INDIA), to assess the effect of microbial inoculants on plant attributes and nutrients uptake by soybean in Vertisols. The experiment was laid out under randomized block design (RBD) with three replications. The 15 treatments comprised of different beneficial microbial consortia in possible combinations applied as seed treatments. The crop was supplemented with recommended dose of fertilizers 20 N : 80 P2O5 : 20 K2O kg ha-1. Besides these, two control plots were maintained as fertilized un-inoculated control (FUI) and unfertilized un-inoculated control (UFUI). The findings revealed that the significant improvement were noticed by the application of consortia NPK+EM+PGPR in plant growth attributes of nodulation at 25, 45 & 65 DAS (71, 70 & 59% respectively), over control (9.5, 33.4 & 34.7 nodule plant-1) and its biomass, (62, 69 & 74% respectively),over the control  (0.58, 1.16 & 0.99 g plant-1),  plant height at 25, 45 & 65DAS were increased 61, 40, 41% respectively, over the control (16.20, 34.90 and 44.30 cm) and plant biomass, (48, 62 & 53%), over the control 1.67, 4.73 and 6.1 g plant-1. Similarly, nutrient uptake (seed & stover) were also increased at 25, 45 and 65 stages of crop growth, with 36.6, 34.8 & 51.3% in seed and 66.7, 98.2 & 67.2% in straw respectively over the control (98.5, 63.8, 5.2, and 7.4, 24.9 and 44.4 kg ha-1 respectively). Thus, it may be concluded that the consortium of NPK + EM + PGPR was superior for sustainable crop production and soil health.

The effect of the nitrification inhibitor 3,4-dimethylphyrazole phosphate (DMPP) on N-fertilized crop growth and soil N<sub>2</sub>O emissions were studied at two experimental sites in Southern Italy, characterised by a Mediterranean climate and different soil texture. The experiments were a randomized block design of two treatments: crop fertilized with NH<sub>4</sub>NO<sub>3</sub> (considered the control treatment) or amended with DMPP plus NH<sub>4</sub>NO<sub>3</sub> (considered the DMPP treatment). ANOVA was performed to assess differences between treatments and fertilization periods whereas simple and multiple linear regressions were performed in order to assess the effect of the soil-related in-dependent variables on soil gases emissions. Growth of potato plants fertilized with DMPP-added nitrogen was enhanced compared to control plants, whereas no benefit on maize plants grown during summer was observed. N<sub>2</sub>O emissions measured from soil to potato after the first fertilization with DMPP-added nitrogen was reduced during winter, but was higher than control after the second fertilizer application in spring, leading to comparable N<sub>2</sub>O emission factors (EF1) between treatments. In maize N<sub>2</sub>O emissions and EF1 were lower for DMPP compared to control treatment. The effectiveness of reduction in soil N<sub>2</sub>O emission was influenced by soil temperature and water-filled pore space (WFPS) in both experimental sites. However, the overall effect of WFPS was contrasting as N<sub>2</sub>O emissions were decreased in potato and enhanced in maize.

A pot experiment was conducted at the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh during the period of November, 2017 to March, 2018 to optimize different levels of Zn and B for better growth and yield attributes of tomato (cv. Ruma VF). The experiment included two factors [factor- A viz., control (Zn0 ), Zn @ 4.0 kg ha-1 (Zn4),  Zn @ 6.0 kg ha-1 (Zn6) and Zn @ 8.0 kg ha-1 (Zn8) and factor B viz., control (B0), B @ 2.0 kg ha-1 (B2) and B @ 3.0 kg ha-1 (B3)], which was laid out in a completely randomized block design with 4 replications, thus total number of pots were 48. Zinc sulphate and boric acid were applied as the source of Zn and B that were applied during pot preparation along with recommended doses of N, P, K and S. The study revealed that application of different doses of Zn increased number of flower clusters plant-1 at 80 days after transplanting, fruit length, fruit diameter, number of fruits plant-1 and yield of tomato up to 4.0 kg ha-1. Similarly, application of B @ 2.0 kg ha-1 produced the highest number of flower clusters plant-1, fruit length and fruit diameter. On the other hand, the highest number of fruits plant-1 and yield of tomato were obtained by the application of B @ 3.0 kg ha-1 which was statistically similar to the application of B @ 2.0 kg ha-1. Combined application of Zn and B, @ 4.0 and 2.0 kg ha-1, respectively appeared as the best practice for better growth and yield of tomato, and therefore it may be recommended to boost up tomato productivity.

Background: Phosphorus (P) and zinc (Zn) are essential plant nutrients and their deficiency in soils has the adverse effect on the crop productivity, moreover the antagonistic effect of P on Zn is also important study aspect. Hence, the present investigation was carried out to study the effect of phospho enriched compost and zinc on productivity, nutrient content and uptake of Blackgram (Vigna mungo L.) in Sub-humid Southern Hills and Aravalli region of Rajasthan. Methods: The experiment was undertaken during Kharif 2018 at Rajasthan College of agriculture, Udaipur (Rajasthan). The treatments comprised of four levels of phospho enriched compost (PEC) i.e. control, PEC @ 2.0, 4.0 and 6.0 t ha-1 and four levels of zinc i.e. control, Zn @ 2.0, 4.0 and 6.0 kg ha-1. The experiment was laid out in a factorial randomized block design with three replications.Result: The increasing levels of phospho enriched compost and zinc upto 4 t ha-1 and 4 kg ha-1, respectively increased significantly (P=0.05) the number of nodules per plant, number of pods per plant, number of seeds per pod, test weight, seed yield, stover yield, nutrient content (N, K and Zn) and uptake (N, P, K and Zn) in seed and stover of blackgram. Whereas, the application of zinc significantly decreased the phosphorus content in seed and stover as compared to control. However, the combined application of phospho enriched compost @ 6 t ha-1 along with zinc @ 6 kg ha-1 was found to record higher seed and stover yield. The application of phospho enriched compost @ 4 t ha-1 and zinc @ 4 kg ha-1 along with the recommended dose of fertilizer results in significantly higher productivity, nutrient content and uptake of blackgram under Typic Haplustepts soil.

Background: Enriched composts supply the plant nutrients and add a sufficient amount of organic matter to the soil, which helps in improving the physical, chemical and biological properties of the soil. It helps to maintain and sustain soil fertility for enhancing crop productivity and also acts as a recess for microbes and enriches the soil with a variety of the indigenous micro-flora and fauna. Hence, the present investigation was carried out to study the effect of fertility levels and enriched compost on productivity, quality and profitability of soybean (Glycine max L.) in sub-humid southern plain and Aravalli hills region of Rajasthan. Methods: The experiment was undertaken during kharif 2018 at Rajasthan College of agriculture, Udaipur (Rajasthan) in a factorial randomized block design with three replications. The treatments were comprised of three levels of recommended dose of fertilizers (RDF) (control, 50% RDF and 100% RDF) and four levels of enriched compost (control, 2.0, 4.0 and 6.0 t ha-1). Result: The increasing fertility levels upto 100% RDF and enriched compost upto 4 t ha-1, significantly increased (P=0.05) the plant height, dry matter accumulation, number of pods per plant, number of seeds per pod, seed yield, haulm yield and protein and oil content in seed of soybean. However, the combined application of 100% RDF along with 6 t ha-1 enriched compost recorded higher seed and haulm yield. The results further revealed that the application of 100% RDF and 4 t ha-1 enriched compost significantly improved the productivity, quality and profitability of soybean under Typic Haplustepts soil.
