EFFECT OF NPK AND ORGANIC FERTILIZERS ON THE GROWTH AND YIELD OF BLACKGRAM IN OLD HIMALAYAN PIEDMONT PLAIN SOIL (AEZ-1) OF BANGLADESH BANERJEE, DIPIKA A field experiment was carried out at the Soil Science Research field in Hajee Mohammad Danesh Science and Technology University, Dinajpur during the kharif season of 2022. This study was performed to examine the effects of organic and inorganic fertilizers on the growth and yield of blackgram. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. There were six treatment combinations viz. T1 = Control (No fertilizer use), T2 = 100% Recommended Dose (RD) of NPK, T3 = 100% RD of Cowdung (CD) + Poultry manure (PM) + Vermicompost (VC), T4 = 75% (CD + PM + VC) + 25% RD of NPK, T5 = 50% (CD + PM + VC) + 50% RD of NPK, T6 = 25% (CD + PM + VC) + 75% RD of NPK, respectively. The yield contributing characteristics like plant height, number of leaves plant-1, number of branch plant-1, number of pods plant-1, pod length, thousand seed weight, seed yield ha-1 and biological yield ha-1 were significantly influenced due to different treatments. In the case of plant height, leaf numbers plant-1, branches plant-1, the highest results were found at different treatments at 15, 30 and 45 DAS but at 60 DAS the highest results were noticed at T5 treatment. The lowest results were obtained in T1 treatment. A significant increase in the NPK contents as well as their uptake due to the combined application of organic manures and NPK was observed. The results of soil indicated that the application of NPK fertilizer and organic manure positively influenced the total N, available P, exchangeable K, and available S contents in soils. Therefore, this study reveals that the application of 50% RD of NPK fertilizers along with 50% (CD + PM + VC) might be an efficient practice for achieving economical blackgram production.

IMPACT OF DIFFERENT SOIL MIXTURES ON THE GROWTH AND YIELD OF RED AMARANTH FOR ROOFTOP GARDENING TAMANNA, SANJIDA A pot experiment was conducted at the Soil Science laboratory-2 of Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of September 2023 to November 2023. The objective of the study was to determine the effect of different soil mixture combinations on the growth and yield of red amaranth. Seven (7) different treatments were: T1 = control (only soil), T2 = 50% soil + 40% vermicompost (VC) + 5% sand + 5% sawdust + 2.0 g kg-1 bone meal powder ,T3 = 45% soil + 45% VC + 5% sand + 5% sawdust + 1.5 g kg-1 bone meal powder ,T4 = 45% soil + 40% VC + 5% sand + 10% sawdust + 1.5 g kg 1bone meal powder ,T5 = 40% soil + 40% VC + 15% sand + 5% sawdust + 2.0 g kg-1 bone meal powder ,T6 = 35% soil + 50% VC + 10% sand + 5% sawdust + 1.0 g kg-1 bone meal powder ,T7 = 35% soil + 50% VC + 5% sand + 10% sawdust + 1.0 g kg-1 bone meal powder. The experiment was laid out in Completely Randomized Design (CRD) with three replications. The soil was sandy loam and the pH, organic matter, total N, available P, exchangeable K and available S were 6.44, 0.64%, 0.014%, 23.72 ppm, 0.128 meq 100g-1 soil and 13.81ppm, respectively. The results showed that the treatment T7 had the highest growth and yield such as plant height (7.67, 20.77, and 51.94 cm at 25, 40, and 55 DAS, respectively), number of leaves per plant (4.74, 9.45, and 19.33 at 25, 40, and 55 DAS, respectively), fresh weight per plant (25.77 g) and total fresh weight per pot (644.25 g). On the other hand, T1 treatment (only soil) had the lowest values of growth and yield characters of red amaranth. In post-harvest soil, different soil mixture combination also had an impact on OM, total N, available P, exchangeable K, and available S content. Therefore, the study reveals that the treatment T7, i.e., application of 35% soil, 50% VC, 5% sand, 10% sawdust, and 1.0 g kg-1 bone meal powder in a mixture combination might be an efficient practice for red amaranth production in urban rooftop.

CHARACTERIZATION OF PIGMENTED RICE GERMPLASMS BASED ON MORPHO-NUTRITIONAL TRAITS, ANTIOXIDANT PROPERTIES AND MOLECULAR MARKERS SALWA, ZEENA The experiment conducted during the Kharif season from April 2022 to November 2022 aimed to analyze the morpho-physiological and nutritional traits, genetic parameters, DNA fingerprinting, and molecular genetic diversity of pigmented rice genotypes. The analysis included ten (10) yield and yield-contributing characters, five (5) nutritional characters, and 14 SSR markers. The experiment revealed significant differences among the genotypes for all traits, showing a good opportunity for selecting better parental types to improve grain yield. The mean performance of different yield and yield contributing characters showed wide variations, with traits like plant height (114.43±2.74) cm, productive tiller per plant (28.85±1.11), unproductive tiller per plant (2.82±0.25), and yield per plant (18.82±1.10) g exhibiting notable ranges. Genetic parameters such as genotypic variance, phenotypic variance, heritability, genetic advance, and genetic advance as a percent of the mean were estimated. The highest genotypic and phenotypic variances were recorded with straw weight (13985.59 and 14158.47), DPPH (4216.64 and 4470.27), days to 50% flowering (1367.09 and 1367.56), iron content (938.47 and 947.76), plant height (373.12 and 395.66), respectively. The low values of phenotypic and genotypic variances were recorded with the character unproductive tiller per plant (1.20 and 1.02), spike per panicle (3.11 and 2.82), thousand seed weight (18.21 and 17.73), respectively. the phenotypic coefficient of variances (PCV) ranged from 17.38% for the plant height to 70.99% for the total phenolic content. The genotypic coefficient of variances (GCV) ranged from 16.88% for the plant height to 70.31% for the total phenolic content. The highest PCV and GCV were observed for the total phenolic content (70.99 and 70.31). The heritability estimation varied from 82.28% to 99.99% for total flavonoid content (TFC) and days to 50% flowering respectively. Furthermore, cluster analysis grouped the genotypes into three clusters based on their traits. Principal component analysis (PCA) identified the minimum number of components explaining the maximum variability principal component 1 (PC1) has an eigenvalue of about 5.77 that captures about 38.5% variance, then the eigenvalue falls steadily in component 4 has an eigenvalue of about 0.99 that captures about 6.6% variance, and the biplot analysis revealed correlations between traits and genotypes. The trait productive tiller per plant, total tillers per plant and panicle length denotes positive PC1 score and negative PC2 score and were highly correlated with each other. Here, the genotypes G21 (BRRI dhan 82), G23 (BRRI dhan 48), G33 (Tepiboro 2), G12 (Nara Bet), G28 (BRRI dhan 29) favored these traits. Again, DPPH content, total flavonoid content and thousand seed weight showed positive loading in PC2 but negative score in PC1. The DNA fingerprinting based on SSR markers identified 57 alleles, and the population structure analysis classified the genotypes into four sub-populations, each with distinct characteristics. The analysis of molecular variance (AMOVA) indicated a higher level of genetic variation (90%) within populations than (10%) among them. The study provides comprehensive insights into the variability, heritability, and genetic diversity of pigmented rice genotypes, offering valuable information for future breeding programs and genetic improvement. Overall, the experiment yielded crucial findings on the diversity, genetic parameters, and population structure of pigmented rice genotypes, such as Orabet aus, Malikhori aus and Narabet aus offering significant implications for breeding and conservation strategies in rice cultivation.

EVALUATION OF FOLIAGE APPLIED BORON ON GROWTH, YIELD ATTRIBUTES AND YIELD OF AROMATIC RICE ETU, MST. NISHAT TASLIM The field experiment was conducted at the research field of Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur-5200, during the period from July 2023 to December 2023 in aman season to observe the growth and yield performance of aromatic rice in response to variety and level of Boron. The experiment comprised of two factors viz. factor A: Varieties; V1 = katarivog, V2 = Kalizira and V3 = Tulsimala; factor B: Levels of Boron; T1 = No application of boron, T2 = 100 ppm, T3 = 200 ppm, T4 = 300 ppm. The experiment was laid out in a RCBD design with three replications. Different variety had significant influenced on growth, yield and yield contributing parameters. The highest plant height (59.92, 108.07, 137.98 and 152.77 cm at 30, 60, 90 DAT and at harvest respectively) was achieved from the variety V2 (Kalizira). The highest number of tillers hill-1 (12.73, 22.75, 28.07 and 22.72 at 30, 60, 90 DAT and at harvest respectively) was obtained from the variety V2 (Kalizira). The highest number of panicles hill-1 (29.98), panicles length (26.83cm), effective tiller (22.45), was found from V2 (Kalizira). On the Other hand different rates of boron foliar application had also significant influenced on growth, yield and yield contributing parameters. The highest number of tillers hill-1 (14.84, 24.82, 29.78 and 22.55 at 30, 60, 90 DAT and at harvest respectively), panicle length (25.602 cm), number of effective tillers hill-1 (21.43), was obtained from T 3 treatment. Again the highest 1000-grains weight (11.87 g), grain yield (3.32 t ha-1), straw yield (7.56 t ha-1), biological yield (10.88 t ha-1), harvest index (31.26%) was obtained from T3 treatment. Interaction effect of variety and splitting different rates of boron as foliar application had also significant influenced on growth, yield and yield contributing characters of aromatic rice. The highest grain yield (3.430 t ha-1) from V2T3 and the lowest yield (2.14 t ha-1) obtained from V3T1 from the combined effect of varieties and Different levels of B doses. The results indicate that the best performing kalizira aromatic rice variety in Bangladesh would benefit by applying 200 ppm of boron.
