Color Sorting Robotic Arm
(IEEE, 2019-02-21) Khan, S.A.; Anika, T. Z.; Sultana, N.; Hossain, F.; Uddin, Mohammad Nasir Uddin
This paper represents the design and implementation of color sorting robotic arm which can detect the exact position of an object and can pick up the object to place it in designated place. This robotic arm is like human arm which can rotate according to its predefined angles. On the other hand, detecting an object on color basis is done by ultrasonic sensor & color sorting sensor. The heart of this project is microcontroller board ATMEGA328P which controls servo motors used in base, elbow, wrist and grip. The prototype of this project was made and used for picking red, green and blue color objects.
EFFECT OF DU<':FERENT LEVEL OF MACRO NUTRIENTS (N, P, K and S) AND THEIR COMBINATIONS ON THE GROWTH AND YIELD OF BROCCOLI
(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2010-07) Khatun, K.; Hossain, F.; Saha, S. R.
An experiment was carried out at the Horticultural Research Farm. of Sher-e Bangia Agricultural University (SAU). Dhaka during the period trorn September 2008 to March 2009. The experiment was laid out in Randomized Complete Block Design with three replications to observe the interaction effects ofN, P. K and S on growth and yield of broccoli. The experiment included 14 treatments using four doses of nitrogen, namely 0, 60, 120, 180 kg/ha, four doses of phosphorus, namely 0, 50, 100, f 50 kg/ha, four doses of potassium. namely 0, 70, 140 ,210 kg I ha and four doses of sulfur (Gypsum) namely. 0, 10, 20, 30 kg Iha. The results of the experiment showed that the application of NPK and S fertilizers influenced growth and curd yield of broccoli. The highest curd yield of broccoli (19.11 t/ha) was obtained from T, (N 120 I'll" K"" S," kg/ha) treatment while the lowest yield (7.52 t/ha) was produced by T1, (No 1'" K" S,' kg I ha) treatment.
EFFECT OF GROWTH REGULATORS ON THE GROWTH AND YIELD OF COWPEA (Vigna unguiculata (L.) WALP.).
(Sher-e-Bangla Agricultural University Research System, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, 2007-07) Ullah, M. J.; Hossain, F.; Fattah, Q. A.
A field experiment was carried out at Sher-e-Bangia Agricultural University, Dhaka, with two growth regulators - Potassium naphthenate (KNap) and Naphthalene acetic acid (NAA) on cowpea cv. Bari Falon-2 under irrigated condition. Three concentrations of KNap (1200, 1300 and 1400 ppm) and two concentrations ofNAA (40 and 50 ppm) along with control were tested. Results showed that the highest plant height was obtained when NAA was applied at the concentration of 50 ppm (91.57 em). Irrespective of treatment, dry matter (OM) increased progressively up to 105 DAS. The treatments 1300 ppm of KNap, 50 ppm of NAA and the combination of 1200 ppm of KNap with 30 ppm of NAA were at par and showed significant higher dry matter, yield attributes and yield. The highest values of dry matter/plant (60.85 g), pod length (14.25 em), number of pods/plant (13.03), number of seeds/pod (10.96), 1000 seed weight (125 g), seed yield/plant (17.85 g), seed yieldlha (1820 kg) and harvest index (37.90 %) were obtained with KNapl300 ppm.
INTEGRA TED MANAGEMENT FOR HIGHER CURD YIELD AND QUALITY OF BROCCOLI (Brassica oleracea var. italica L.)
(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2014-01) Khatun, K.; Hossain, F.; Saha, S. R.; Mostarin, T.
An integrated management was taken to investigate the effect of macronutrients, micronutrients, cowdung, mustard oilcake and mulches on different yield contributing characters, yield and quality parameters of broccoli during October 2011-March 2012 at the Horticulture Farm, Sher-e-Bangia Agricultural University, Dhaka. The experiment included six treatments using T,= 15 tlha Cowdung + NlIsP"K'20 (recommended dose of cauliflower) ,T2= IS tlha Cowdung + N'20P,ooK,.oS20kg/ha ,T3= IS tlha Cowdung + N'20P,ooK'40S20+ Zn.Bl.sMo, kglha, T.= 20 tlha Cowdung + 400 kglha mustard oilcake , Ts= N120P'OOK140S20+Zn .BuMol kg/ha + 20 tlha Cowdung + 400 kg/ha mustard oilcake and water hyacinth mulch ,T6= NI2OP,OOK,.oS20+Zn.BuMol kglha + 20 tlha Cowdung + 400 kg/ha mustard oilcake. Significant variation was recorded in case of plant height, number of leaves, leaf length, leaf breadth, days to curd initiation, stem length, stem diameter, primary curd diameter, curd weight, number and weight of secondary curd, curd yield, moisture (%) , ascorbic acid, ~ carotene content, protein and carbohydrate percentages except total fat percentages, iron and calcium content. The maximum curd yield (24.15 t/ha) was found from T6 treatment and the minimum was recorded from T4 (15.26 tlha) treatment. T6 treatment showed the best performance on the maximum yield and quality curd production over all the other treatments.
YIELD OF BROCCOLI AS INFLUENCED BY COWDUNG AND MUSTARD OILCAKE
(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2014-07) Khatun, K.; Hossain, F.; Saha, S. R.; Mostarin, T.; Begum, F.
The experiment was conducted during October, 2009 to March 2010 at the Horticulture Research Farm of Sher-e-Bangla Agricultural University, Sher-e Bangia Nagar, Dhaka to determine the response of organic manure on yield, quality and economic benefit of broccoli. The experiment included 16 treatments with 4 levels of cowdung manure (0, 10, 20 and 30 tlha) and 4 levels of mustard oil cake (0, 300, 400 and 500 kg/ha) were used to study the effect of these on broccoli production. All treatments showed significant influence on days to curd initiation, primary curd diameter, stem diameter, primary curd weight, number of secondary curds per plant, weight of secondary curds. dry matter content of curd. curd yield but it did not show any significant effect on chlorophyll a and b content in leaves. moisture(%), protein (%) ascorbic acid content of curd. The maximum curd yield per hectare (15.27 tlha) were found from the C2M2 (20 tlha cowdung + 400 kg/ha mustard oil cake) treatment and the minimum curd yield (8.07 tlha) was obtained from the control.
