EFFECT OF NITROGEN LEVELS ON GROWTH, YIELD AND SEED QUALITY OF WHEAT
(DEPARTMENT OF AGRONOMY, 2015-06) AKTER, MAHBUBA
A field experiment was conducted at the Research Field and Agronomy Laboratory of Shere-Bangla Agricultural University, Dhaka 1207 during the period from November, 2014 to March, 2015 to evaluate the effect of nitrogen levels on growth, yield and seed quality of wheat. The experiment comprised of five nitrogen levels viz. (i) N = Control (no nitrogen), (ii) N 1 = 25% less nitrogen from the recommended dose, (iii) N 2 0 = Recommended dose of nitrogen, (iv) N 3 = 25% higher nitrogen than recommended dose, (v) N = 50% higher nitrogen than recommended dose and four wheat varieties viz. (i) V 1 4 = BARI gom 21, (ii) V = BARI gom 23 (iii) V 3 = BARI gom 24 and (iv) V = BARI gom 27. The experiment was laid out in a split plot design with three replications. Data were collected on different parameters of growth, yield attributes, yield and seed quality of wheat. Results revealed that N 4 (25% higher nitrogen than recommended dose) gave the highest grain yield (3.41 t ha-1) which was statistically at par with N (recommended dose of nitrogen) (3.29 t ha-1). This might be attributed to highest number of spikes m 2 -2 (194.46), spike length (15.61 cm), number of spikelets spike -1 (20.91), number of grains spike -1 (48.17) and 1000-grain weight (47.08 g). Out of 4 varieties V 3 (BARI gom 24) showed highest grain yield (3.02 t ha ) which was statistically similar with V 4 (BARI gom 27) (2.89 t ha -1 -1 ). The variety BARI gom 27 (V ) also showed higher number of grains spike -1 (46.65) and 1000-grain weight (49.53 g). In respect of seed quality, N (recommended dose) showed higher quality of seed which was statistically similar to N 2 (25% higher nitrogen dose than recommended) because this nitrogen dose gave highest germination percentage (96.67 %), vigor index (10.34), shoot length (19.94cm) and dry weight seedling 3 -1 (0.19 g). In the case of variety, V (BARI gom 27) showed the higher seed quality attributes of germination percentage (95.20%), vigor index (10.52) shoot length (20.51cm) and dry weight seedling -1 (0.18 g). Regarding the interaction of nitrogen doses and varieties, N 2 V 3 , N 2 V 4 and N 3 V were shown best in producing quality seeds. From the above results it was concluded that the recommended dose and 25% higher nitrogen than recommended dose with BARI gom 27 shows better for producing higher yield and quality seed. 4 4 2 3 4
IMPACT OF WOMEN EMPOWERMENT IN AGRICULTURE ON CHILD LABOUR IN NARSINGDI DISTRICT OF BANGLADESH
(DEPARTMENT OF AGRICULTURAL ECONOMICS, 2022) AKTER, MAHBUBA
One of the most effective strategies for reducing child labour is women empowerment. The key purpose of the present study is to investigate the impact of women empowerment through agriculture and reduction of child labour in some villages at Narsingdi district in Bangladesh. A pre-structured questionnaire was used to collect data through face to face interview from randomly selected sample size of 100 respondents from some villages. The logistic regression model is used here to assess the impact of women’s empowerment on child labour. The main findings indicated that about 98% respondents had child helping hand who don’t use to go to school, but after starting work of the women of that family the education, nutrition of the chlildren increases. Agriculture as well as livestock rearing was the main occupation among the respondents. Most of the respondents were found owner and labour of their work. Their main source of income provided from some occupation like- business, service, fish farming, livestock rearing, and day laboring. The respondents have overall good farming experience. Most of the respondents (99%) have Leadership quality and were able to make their own decision. The economic participation rate in family of the respondents was very high (100%), on the other hand they (18%) had little loan opportunities. The study suggests that there needs a lot of work for empowering women to eradicate child labour. Government and nongovernment organizations should take proper step to increase women empowerment as well as ensure women’s fundamental rights make their life easy and make them more empowered so that women can generate income and be provided with greater access to finance then families can be lifted out of poverty and children are more likely to stay in school. Because the additional income helps families to mitigate the need to rely on children for labour. As a result, it is apparent that as women empowerment rises the problem of child labour decreases
PERFORMANCE OF CAULIFLOWER PRODUCTION UNDER MANGO BASED AGROFORESTRY SYSTEM INFLUENCED BY SPACING AND FERTILIZER IN CHARLAND
(HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR., 2020-06) AKTER, MAHBUBA; Prof. Dr. Md. Shafiqul Bari
A field experiment was conducted in the charland of Gangachara Upazilla under Rangpur district during October, 2019 to December, 2019 to evaluate the performance of cauliflower production under mango based agroforestry system influenced by different plant spacings and different fertilizer application packages. The experiment was laid out in a two factorial RCBD with 3 (three) replications. Factor A was three plant spacings viz. S1= 75 × 50 cm (Broader spacing), S2= 60 × 45 (Intermediate spacing), S3= 50 × 40 (Closer spacing) and Factor B was four Fertilizer and manure application packages viz. F0= No Fertilizer, F1= Cow-dung, F2= Poultry manure and F3= Chemical fertilizer. The total number of experimental plots were 36. The result of the experiment revealed that plant height (30, 60 and 75 DAP) as cm, number of leaves/plant (30, 60 and 75 DAP), outer leaf length (30, 60 and 75 DAP) as cm, outer leaf width (30, 60 and 75 DAP) as cm, yield curd weight without leaf/plant (g), yield of curd without leaf/plot (kg/ha) and yield of curd without leaf/hectare (t/ha) of cauliflower significantly varied due to different plant spacings and fertilizer and manure applications at cultivated under the mango based agroforestry system. In case of main effect of different plant spacings, the maximum curd yield without leaf (14703 kg/ha) was recorded from the closer spacing i.e. 50 cm x 40 cm (S3). On the other hand, the minimum yield (8.8 t/ha) was recorded from the broader spacing i.e. 75cm × 50 cm (S1). In case of main effects of fertilizer and manure applications, the highest curd yield without leaf (17.1 t/ha) was recorded from the plot where fully chemical fertilizer (F3) was applied whereas the lowest yield (8.7 t/ha) was obtained from the plot where no fertilizer (F0) was applied. Again, in case of interaction effects of the different plant spacings and fertilizer and manure applications, the maximum curd yield without leaf (49.73 t/ha) was recorded in the plot where maintained closer spacing i.e. 50cm x 40 cm with chemical fertilizer (S3F4) whereas the minimum curd yield without leaf was (20.97 t/ha) was recorded in the plot where maintained broader spacing i.e. 75 cm x 50 cm with no fertilizer (S1F1). Similarly, the maximum curd yield without leaf per hectare (21.48 t/ha) was recorded in the plot where maintained closer spacing i.e. 50 cm x 40 cm with chemical fertilizer application (S3F3). On the other hand, the minimum curd yield without leaf per hectare (6.52 t/ha) was recorded in the plot where maintained broader spacing i.e. 75 cm x 50 cm with no fertilizer application (S1F0). From the economic analysis, the highest benefitcost ratio (4.08) was recorded from the treatment 75 cm x 50 cm i.e. broader spacing + Chemical Fertilizer application (S1F3). The lowest benefit-cost ratio (1.74) was observed in those plots where cauliflower was grown under 60 cm x 45 cm i.e. intermediate spacing with no fertilizer (S2F0) application. Moreover, in case of economic return, cauliflower cultivation at the floor of mango tree with broader planting space and the application of full chemical fertilizer gave maximum BCR
