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. EFFECT OF NPK AND ORGANIC FERTILIZERS ON THE GROWTH AND YIELD OF BLACKGRAM IN OLD HIMALAYAN PIEDMONT PLAIN SOIL (AEZ-1) OF BANGLADESH; A THESIS BY DIPIKA BANERJEE, Student No. 1501164, Session: July- December 2023, MASTER OF SCIENCE (M.S.)

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. IMPACT OF DIFFERENT SOIL MIXTURES ON THE GROWTH AND YIELD OF RED AMARANTH FOR ROOFTOP GARDENING; A THESIS BY SANJIDA TAMANNA, Student No. 1701207, Session: July-December, 2023, MASTER OF SCIENCE (M.S.) in SOIL SCIENCE, DEPARTMENT OF SOIL SCIENCE, HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY DINAJPUR-5200; DECEMBER, 2023. 2023-06-01T00:00:00Z http://103.7.193.12:8080/xmlui/handle/123456789/2090 EFFECT OF INORGANIC FERTILIZER ON THE VEGETATIVE GROWTH OF DRUMSTICK (Moringa oleifera) ROY, PROTIMA RANI A field experiment was carried out at the Soil Science research field in Hajee Mohammad Danesh Science and Technology University, Dinajpur during the rabi season of 2022. This study was done to examine the effects of inorganic fertilizer on the growth and yield of drumstick. The experiment was laid out in the Randomized Complete Block Design (RCBD) with three replications. There were six treatment combinations viz. T1: No fertilizer (control), T2: RDF NPKS, T3: N10P20K20, T4: N20P20K20, T5: N30P20K20, T6: N40P20K20, respectively. The result showed the yield contributing characteristics except plant height were not significantly influenced by different treatments used in the experiment. The highest value of plant height (at 15 DAT, 30 DAT and 60 DAT, 86.13 cm, 107.63 cm and 126.13 cm, respectively), number of leaves plant-1 (at 15 DAT, 30 DAT and 60 DAT, 9.33, 18.33 cm and 24.93 cm, respectively), diameter of the stem (at 15 DAT, 30 DAT and 60 DAT, 3.53 cm, 6.89 cm and 10.79 cm, respectively) was recorded in the treatment T5 (N30P20K20), among the combined application of inorganic fertilizer. Application of N30P20K20 exerted beneficial effects on yield and yield contributing characteristics of drumstick compared to control. Analyses of post-harvest soil fertility status revealed that the application of inorganic fertilizer positively influenced the total N, available P, exchangeable K, and available S contents in soils. In post-harvest soil application of NPK gave positive result. It also increased soil fertility status.

The experiment was laid out in Randomized Complete Block Design (RCBD) having six treatments with three replications. The treatments were as follows; T1 = Control, T2 = 100% NPK, T3 = 100% compost, T4 = 25% NPK + 75%compost, T5 = 50% NPK + 50% compost, T6 = 75% NPK+ 25% compost. The experimental soil belongs to the Old Himalayan Piedmont Plain (AEZ-1). The soil was sandy loam in texture having pH 5.60, organic matter content 1%, total N 0.080%, available P 3.30 ppm, exchangeable K 0.52 meq 100 g-1 soil and available S 7.53 ppm. The application of NPK and compost had a significant effect on the growth and vegetative yield of red amaranth. The tallest plant height (5.90, 21.40, and 26.31 cm at 15, 30, and 45 during final harvest respectively) was found in the treatment T6 and the shortest plant height (4.50, 9.06, and 13.96 cm at 15, 30, and 45 during final harvest, respectively) was observed in T1 (control). The maximum number of leaves (4.70, 8.34, 10.40 at 15, 30, and 45 during final harvest, respectively) was recorded in the treatment T6 whereas the minimum number of leaves (3.79, 5.90, 7.50 at 15, 30, 45 during final harvest, respectively) was found in the T1 (control). Application of NPK and compost resulted in a considerable influence on the properties of the post-harvest soils such as the highest total N (0.160%), available S (6.53 ppm) inT3 treatment and soil organic matter content (1.40 %) and EC (0.21 mSm-1) in T6 treatment. The treatment T6 produced the highest both fresh and dry shoot weight (3.78 and 1.83 t ha-1 respectively) but the lowest fresh and dry shoot weight (1.14 and 0.56 t ha-1 respectively) was obtained from the control treatment (T1). The maximum fresh and dry root weight (1.41 and 0.76 t ha-1, respectively) and tallest root length (7.80 cm) was recorded from the treatment T6 and the minimum both fresh and dry root weight (0.42 and 0.21 t ha-1, respectively) and smallest root length (6.30 cm) was observed in the T1 (control). It was obvious that fertility of soil and vegetative growth of red amaranth can be increased substantially with the judicious application of compost with chemical fertilizers. The findings of the study showed that the performance of treatment T6 was the best among all treatments. This study suggests that amendment of soil with 75% NPK + 25% compost might be an efficient practice for achieving sustainable soil fertility and vegetative growth of red amaranth.
