Optimizing rice (Oryza sativa) growth, productivity, profitability and nutrient uptake with coated urea and organic manure in the new alluvial zone of West Bengal

A two-year field experiment was carried out at experimental farm of BCKV, Nadia, West Bengal during kharif seasons of 2019–20 and 2020–21 to study the effect of combined application of coated urea and organic manure on performance of rice. The experiment was laid-out in a randomized complete block design with four replications and treatment comprised 5 treatment combinations, such as T1 , control plot (without N); T2 , 100% recommended dose of nitrogen (RDN) through neem-coated urea (NCU); T3 , 75% RDN through NCU + 25% RDN through FYM (farm yard manure); T4, 100% RDN through polymer sulphur coated urea (PSCU); T5, 75% RDN through PSCU+25% RDN through FYM. The results showed that 75% RDN through PSCU+25% RDN through FYM re- sulted in maximum growth attributes, viz. plant height (110.8 cm), maximum number of effective tillers per square meter (416/m2 ), highest dry-matter accumulation (DMA) (740 g/m2 ), leaf area index (LAI) (4.47) and crop growth rate (CGR) (6.56 g/m2 /day), highest yield components like panicle length (23.5 cm), panicle weight (9.95 g), num- ber of filled grains/panicle (113), test-weight (21.3 g) and maximum grain yield (4.79 t/ha) and straw yield (5.53 t/ ha). Similarly, maximum amount of total nutrient uptake by crop (99.7, 40.1 and 208 kg/ha NPK), protein yield (418 kg/ha), gross returns (` 71.8 × 103 /ha), net return (` 52 × 103 /ha) and B: C ratio (2.73) were noticed under T5 treat- ment. Therefore, it is advisable to implement a comprehensive nutrient management strategy T5 (75% RDN through PSCU + 25% RDN through FYM) in rice cultivation. This approach enhances growth, yield, nutrient absorption, and quality, ultimately boosting agricultural productivity, profitability, and sustainability.

Treating Radiation-induced Aceh Rice Germplasm with Arbuscular Mycorrhizal Fungi has been Shown to Effectively Address Bacterial Leaf Blight

Background: Bacterial leaf blight can damage upland rice and reduce yield by 30-40%. Chemical pesticides harm ecosystems and can increase pathogen resistance. The objective of this research was to explore the potential of AMF, a biological agent, to enhance the resistance of local Acehnese-radiated mutant rice against bacterial leaf blight. Methods: Two-factor factorial design with three levels of AMF dosage (0 g, 10 g and 20 g per plant) and three upland rice lines (UA-01, UA-09 and UA-10). There were 9 treatment combinations replicated 3 times, resulting in 81 experimental units. Result: The intensity of the disease decreased significantly as the dosage of AMF increased and the maximum number of tillers increased substantially up to 20 g plant-1 AMF application. UA-10 strains exhibited the highest number of tillers per clump, while UA-09 strains had the lowest. The interaction between local Aceh rice varieties and AMF did not impact bacterial leaf blight intensity, maximum number of tillers and percentage of filled grain, except for AMF colonization on roots. The significance of AMF colonization varied among lines, with the highest AMF colonization observed in the UA-10 strain (20.64%) at an AMF dose of 20 g plant-1. AMF inoculation appeared to affect the percentage of filled grain positively.

The Effect of Biological Fertilizers and Inorganic Fertilizers on Upland Rice Plants (Oryza sativa L.) Growth and Production

Upland rice (Oryza sativa L.) is a staple food crop that produces rice, which is important in meeting Indonesia's food needs. This research aims to improve growth and increase the production of upland rice plants by providing biological fertilizer and inorganic fertilizer and getting the right combination dose for upland rice plants. This research was carried out at the experimental garden of the Faculty of Agriculture, Riau University, Bina Widya campus km 12.5, Pekanbaru. This research used a factorial completely randomized design (CRD) consisting of two factors the first factor was biological fertilizer consisting of four levels, namely: H0 : Control, H1 : 0.18 g of Agrimeth fertilizer, H2 :0.41 g Kayabio fertilizer, H3: 0.45 g Petro Biofertil fertilizer; The second factor is Phonska NPK fertilizer consisting of four levels, P0 : control, P1 : 1,4 g, P2: 2 g, P3 : 2.7 g per plant. The results showed that the interaction between the application of biological fertilizer and NPK Phonska fertilizer affected the number of grainy grains per panicle and the weight of milled dry grain. Providing biological fertilizer affects plant height, root dry weight, shoot dry weight, maximum number of tillers, number of productive tillers, number of grainy grains per panicle, percentage of grainy grains and weight of milled dry grains. Application of NPK Phonska fertilizer affects plant height, shoot dry weight, root dry weight, maximum number of tillers, number of productive tillers, number of grainy grains per panicle, percentage of grainy grains and weight of milled dry grains. The correct dose to improve the growth and production of upland rice plants of the Inpago 12 variety can be 0.45 g Petro Biofertil Biofertilizer with 2.7 g Phonska NPK per plant

The higher buildup of organic soil carbon (0.43%) and available N (174.11 kg/ha), P (18.98 kg/ha), S (14.88 ppm), DTPA-Zn (0.65 ppm) and B (0.55 ppm) in was maintained or slightly increased in soil test-based recommendation and customized fertilizers applied plots. While higher availability of K (259.80 kg/ha) was found in RDF. The higher net returns (32.58 × 103 `/ha) per rupee investment and B:C ratio (0.82) was also recorded in Soil test-based recommendation followed by Indo-Gulf customized fertilizer and TCL customized fertilizer.

Morphological Trait based Genetic Divergence and Correlation in Barley Genotypes for Drought Tolerance

An experiment was conducted to explore the genetic diversity for the selection and utilization of drought-tolerant barley genotypes in future breeding approaches for yield enhancement. The experimental material comprised thirty barley genotypes planted at the Barley Research Area, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar, under drought conditions during 2015-16 and 2016-17. All the genotypes were classified into four distinct clusters. Cluster IV occupied the maximum number of genotypes, i.e. 17, followed by cluster I with eight genotypes. Cluster II and III possessed three and two genotypes, respectively. The average inter-cluster distance was found to be highest between clusters II and III (261.7), followed by clusters III and IV (188.1), while the lowest inter-cluster distance was observed between clusters II and IV (73.8). Cluster I, comprised of eight genotypes, exhibited maximum germination per cent. Cluster II consisted of three genotypes, characterized by high initial vigour, early heading and minimum plant height. Two genotypes from cluster III exhibited minimum internode length, longest spike, and maximum number of tillers per meter and were also found promising for the traits viz., culm thickness, number of grains per spike, 1000-grain weight and grain yield per plot. Cluster IV, being the largest one, had 17 genotypes with the characteristic features of early maturity. Number of effective tillers per meter showed significant positive correlation with grain yield per plot. This trait could be used as a key component in the screening and selection of drought-tolerant genotypes. The improvement in barley could be achieved through the use of genotypes namely JB 481 and Lakhan assigned in clusters III. These genotypes might be considered as potential parents to obtain high heterotic response and accordingly better segregant for grain yield under drought condition.

Quantitative trait loci detection for three tiller-related traits and the effects on wheat (Triticum aestivum L.) yields.

A total of 38 putative additive QTLs and 55 pairwise putative epistatic QTLs for tiller-related traits were reported, and the candidate genes underlying qMtn-KJ-5D, a novel major and stable QTL for maximum tiller number, were characterized. Tiller-related traits play an important role in determining the yield potential of wheat. Therefore, it is important to elucidate the genetic basis for tiller number when attempting to use genetic improvement as a tool for enhancing wheat yields. In this study, a quantitative trait locus (QTL) analysis of three tiller-related traits was performed on the recombinant inbred lines (RILs) of a mapping population, referred to as KJ-RILs, that was derived from a cross between the Kenong 9204 (KN9204) and Jing 411 (J411) lines. A total of 38 putative additive QTLs and 55 pairwise putative epistatic QTLs for spike number per plant (SNPP), maximum tiller number (MTN), and ear-bearing tiller rate (EBTR) were detected in eight different environments. Among these QTLs with additive effects, three major and stable QTLs were first documented herein. Almost all but two pairwise epistatic QTLs showed minor interaction effects accounting for no more than 3.0% of the phenotypic variance. The genetic effects of two colocated major and stable QTLs, i.e., qSnpp-KJ-5D.1 and qMtn-KJ-5D, for yield-related traits were characterized. The breeding selection effect of the beneficial allele for the two QTLs was characterized, and its genetic effects on yield-related traits were evaluated. The candidate genes underlying qMtn-KJ-5D were predicted based on multi-omics data, and TraesKN5D01HG00080 was identified as a likely candidate gene. Overall, our results will help elucidate the genetic architecture of tiller-related traits and can be used to develop novel wheat varieties with high yields.

Genetic evaluation of hulless barley (Hordeum vulgare) genotypes for morpho-physiological traits and stripe rust resistance

Nowadays, hulless barley (Hordeum vulgare L.) is gaining importance as a raw material for food industry due to its highly nutritive value. Non-availability of high yield and disease resistant varieties has restricted its production in marginal areas over the last two decades. Therefore, an experiment was conducted during 2017–18 and 2018–19 at the Seed and Research Farm of ICAR-Indian Institute of Wheat and Barley Research, Karnal, Haryana to characterized 11 exotic hulless barley genotypes and 4 Indian barley cultivars for morpho-physiological characters and stripe rust resistance. Seedling resistant test for stripe rust was done at Regional Station (ICAR-Indian Institute of Wheat and Barley Research), Flowerdale, Shimla, Himachal Pradesh. Highly significant genotypic differences were found for morpho-physiological traits during analysis of variance. Genotype DWRNB28 showed a good combination of desirable traits, viz. early maturity (118 days), dwarf plant height (64.4 cm) and high 1000-grain weight (55.2 g). Maximum number of tillers per meter (149) was observed in DWRNB17. Genotype DWRNB25 was found resistant to maximum pathotypes (6S0, 7S0, and Q) at the seedling stage. DWRNB23 and DWRNB25 with pooled ACI=0 and ACI=0.04 respectively, were found immune to stripe rust in field conditions. These promising genotypes can be utilized as donor parents for the development of high-yielding and stripe-rust-resistant hulless barley varieties.

The highest grain and straw yield were observed 54.47 qha­-1 and 64.49 qha-1 in the treatment 75% RDF + 25 % N through FYM + GM + VC. The treatment combination 75 % RDF + 25 % N through FYM + GM + VC came out to be the best dose for most of the characters of the rice crop under study.

Response of Transplanted Rice to Seedling Root-dip in Phosphorus and Biofertilizer Slurry in Acid Soils of North East India- A Participatory Assessment in Farmers’ Field

Background: Rice production is mainly constrained by low P-use efficiency (PUE) and P-recovery efficiency (PRE) in acid soils of the North East hill region of India. Efficient P fertilizer management strategies for rice production is very essential to achieve higher yield per unit of P fertilizer applied. Rhizosphere-based P management in wetland rice is considered as an efficient strategy to minimize the quantity of applied P to obtain a profitable yield. Methods: Seedling root dipping in P slurry technique in farmers’ field condition was studied in comparison to the conventional methods of application of recommended dose of fertilizer (RDF) and the integrated nutrient management (INM) practices to identify a suitable cost effective method of application of phosphatic fertilizer for the acid soils of this hill region of North East India. Result: The highest plant height, maximum number of effective tillers and root biomass were recorded in SSP root dip+Phosphate Solubilizing Bacteria (PSB) followed by INM practices. P root dip had greater root biomass (4.36 g plant-1) which was significantly higher than RDF (3.82 g plant-1). Root dip application showed higher yields (5.80 t ha-1), compared with INM (5.53 t ha-1) and RDF (5.46 t ha-1) and control (4.25 t ha-1). The result of the present study demonstrated that P-dipping can achieve high applied P use efficiency (1193.42) in transplanted rice compared to conventional incorporation of P (625.43). Thus, P-dipping is a potential strategy to overcome low applied P use efficiency in high P-fixing soils and hence reduces the need for excess P application.

Effect of plant spacing and harvesting age on morphological characteristics and yield of Desho grass ( Pennisetum glaucifolium L.) at Adola sub-site of Bore Agricultural Research Center, Oromia Region, Ethiopia.

Abstract This study was carried out in the Adola sub-site of the Bore Agricultural Research Centre in order to assess the effects of suitable harvesting age and plant spacing on the morphological traits and yield of Desho grass. Randomized complete block design (RCBD) with 3*3 factorial configurations in three replications was used to set up the experiment. The experiment makes use of three plant spacing (10, 30 and 50 cm) and three harvesting stages (75, 105, and 135 days). Prior to planting 100 kg/ha -1 combinations of Nitrogen, phosphate and sulfur (NPS) fertilizer were applied to all plots. The data collected from the study includes morphological characteristics such as; plant height (PH), leaf length per plant (LLPP), number of leaves per plant (NLPP), number of tillers per plant (NTPP), Leaf to steam ratio (LSR), dry matter yield (DMY), survival rate (SR), Plot cover (PC), and vigorousity. All data were subjected to GLM ANOVA procedures of SAS, 2002 version 9.0. The results revealed that all morphological characteristics were significantly (p < 0.01) affected by the treatments except leaf to steam ratio and plot cover The minimum mean number of tiller per plant (NTPP) of 21.53 was obtained from 10*75 treatments while the maximum number of tiller per plant (NTPP) of 59.3 was recorded from 50*135 treatments. The highest plant height (100.43 cm) was recorded from 30*105 treatments, while the lowest plant height was obtained from 30*75 treatments. The highest (31.87) dry matter yield tone per hectare was recorded from 30*105 while the lowest (4.4) were obtained from 50*75 treatments. It is possible to draw the conclusion that, in the current experiment near Adola, the treatment combination of 30 cm*105 days has produced the best production and nutritional values of Desho grass. To reach trustworthy results, more research on various combinations of harvesting stage and plant spacing across years and regions is necessary.

Rice (Oryza sativa L.) Growth and Production in Main Square System Treatment with Liquid Organic Fertilizer of Gold Snails (Pomacea caniculata L.) and Citronella Oil (Cymbopogon nardus (L.) Rendle)

The use of artificial chemicals as fertilizers and pesticides can endanger the health of the environment and consumers, so the potential utilization of natural materials as fertilizers and pesticides needs to be increased from local sources such as golden snails and citronella. The experiment aims to get the best interaction between golden snail Liquid Organic Fertilizer (LOF) and citronella oil for rice growth and production. The experiment was carried out in the paddy fields of Jorong Paraman Ampalu, Gunung Tuleh District, West Pasaman Regency from September 2020 to January 2021 using an RBD of 2 factors with 3 replications. The first factor was the golden snail LOF concentration, namely: 0, 100, 200, and 300 ml/L. The second factor was the citronella oil concentration, namely: 0, 10, 20, and 30 ml/L. Data were analyzed with ANOVA and DNMRT at 5% and 1%. The experimental results showed that the interaction between golden snail LOF and citronella oil concentration accelerated flowering, increased panicle length, grain weight, and dry grain production per hectare, while the golden snail LOF concentration factor increased plant height, maximum number of tillers and productive tillers, panicle length, number of grains per panicle, and 1000 grain weight. The highest grain production was obtained at concentrations of golden snails LOF of 200 ml/L and citronella oils 20 ml/L, namely 9.18 t/ha. The frequency of attacks by ground beetles and golden snails decreased at a concentration of 30 ml/L citronella oil, while stink bug infestation frequency was reduced at a concentration of 10 ml/L.

Determining nitrogen topdressing rates in accordance with actual seedling density and crop nitrogen status in direct-seeded rice.

Adjusting nitrogen (N) input based on actual seedling density (ASD) and plant N status is a practical approach for improving the yield stability of direct-seeded rice. However, the adjustment of topdressing N rates has been empirical in the past. This study aimed to establish a quantitative approach for determining N topdressing rates during tillering (Ntil ) and panicle development (NPI ) based on ASD and crop N status in direct-seeded rice. Field experiments were conducted involving 12 treatments, consisting of four Ntil and three seeding rates in 2017, and eight treatments combining seeding rate, Ntil , and NPI in 2020. Linear regression analysis revealed that the tiller number at panicle initiation (TILPI ) was predominantly influenced by ASD and Ntil . The determination coefficients (R2 ) of the regression models ranged from 0.887 to 0.936 across the four-season experiments. The results indicated that Ntil could be determined accurately using ASD and the target maximum tiller number. Similarly, grain yield was influenced significantly by the N uptake at panicle initiation (NUPPI ) and NPI , with R2 of 0.814 and 0.783 in the early and late seasons of 2020, respectively. This suggested that NPI could be calculated based on NUPPI and the target grain yield. The findings offer a quantitative method for establishing N topdressing rates for tillering and panicle development, relying on the monitoring of actual seedling density and plant N status in direct-seeded rice production. © 2023 Society of Chemical Industry.

MORPHOLOGICAL CHARACTERIZATION OF ORCHARDGRASS (Dactylis glomerata L.) NATURALLY SPREAD IN EASTERN ANATOLIA, TÜRKIYE

Orchardgrass (Dactylis glomerata L.) is a cold-resistant, perennial and one of the main forage species of meadows and pastures. A total of 9 morphological traits were considered for the morphological characterization of the orchardgrass, which is naturally distribusted in the flora of 43 different locations in 8 provinces of the Eastern Anatolia of Türkiye. According to the analysis of variance; significant differences were determined between genotypes in terms of the morphological traits examined. These differences resulted in a high degree of phenotypic variation. In addition, correlation coefficient analysis showed a significant (P<0.01) and positive relation between most of the traits examined. The highest correlation coefficient was between plant height and peduncle length (0.864**), flag leaf length and flag leaf width (0.765**), flag leaf length and panicle length (0.734**) The first five Principal components (PCA) explained 70.31 % of the total variation in orchardgrass genotypes. The highest plant height and maximum number of tillers, which are important for grass yield and reproduction, were determined in M75 (77.57 cm) and R163 (27.85 per/plant) respectively. The high morphological variation among orchardgrass genotypes indicates the existence of a rich genetic population and can be considered as breeding material. Keywords: Türkiye, Eastern Anatolia, morphological characterization, phenotypic variation, Dactylis glomerata, orchardgrass.

A field experiment was conducted during rabi 2022-23 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P) to determine the “Effect of Nitrogen management on growth and yield of wheat”. There were nine treatments each replicated thrice and the experiment was laid out in Randomized Block Design. The results showed that treatment 6 (75% N through urea + 25 % N through poultry manure) recorded significantly higher plant height (119.20 cm), maximum number of tillers/ m2 (214), higher plant dry weight (64.34 g), highest Crop growth rate during the interval of 50-75 DAS (35.73 g/m2/day), maximum number of effective tillers/ m2 (144.5), maximum number of grains/ spike (53.33) and highertest weight (97.71 g) compared to other treatments.

Assessing the Effect of Irrigation Levels and Hydrogel on Growth and Yield of Wheat (Triticum aestivum L.)

One of the most essential inputs for agriculture is water. Moisture stress at critical growth stages in wheat severely effects the growth and yield. Hydrogel (water-absorbing polymer) can keep the appropriate moisture level at the root zone depth and protects the crop from adverse effect of moisture stress. The present trial was conducted during rabi season of 2020-21 to assess the performance of different hydrogels under different levels of irrigations on growth, yield, and water use efficiency of wheat. Results revealed that application of 3 irrigations recorded significantly maximum number of tillers per m2 at 90 Days After Sowing and at harvest. The application of Nano hydrogel @ 20 kg ha-1 significantly increased the number of tillers per m2 at 90 DAS and at harvest over control. Significantly maximum grain (26.1%) and straw (24.5%) yield were obtained with 3 irrigation levels over one irrigation. The Nano hydrogel increased grain (33.6%) and straw (22.9%) yield significantly over control. Water use efficiency significantly improved with one irrigation over 3 irrigation levels, application of Nano hydrogel @ 20 kg ha-1 significantly increased WUE.

(41.17 and 42.13 gm), grain yield (48.60 and 49.93 q ha-1) and straw yield (63.15 and 67.53 q ha-1) have been observed in the treatment T10 [100 % NPK + S40 + Zn5 + Fe10 + Azotobacter + PSB + 5 tonne FYM] during both the years of the experimentation. The objective of the study to understand how different combinations of inorganic fertilizers, organic manure, and biofertilizers affect the growth and productivity of wheat, specifically the HD-2967 variety, when grown using recommended agronomic practices.
