An experiment was conducted at the research field of Jute Research Regional Station of Bangladesh Jute Research Institute (BJRI) at Kishoreganj during August 2009 to January 2010 to assess the effect of cutting length and position of cutting on seed yield and quality of tossa jute (Corchorus olitorius L.). Three cutting lengths (15 cm, 20 cm and 25cm) and three cutting positions (1st top, 2nd top and 3rd top) were the treatments. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The highest seed yield (917 kg ha-1) was obtained from 1st top x 15cm interaction and the lowest (811 kg ha-1) was recorded in 3rd top x 25cm cutting length. The highest seed germination (89%), field emergence (87%) and accelerated ageing (73%) were recorded from 1st top x 15cm interaction and the lowest seed germination (83.00%), field emergence (81%) and accelerated ageing (72) were recorded in 3rd top x 25 cm cutting length. The upper position of cutting produced the highest yield and best quality seeds. The Agriculturists 2018; 16(1) 13-20

Pollen Quantity

Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen resulted in higher seed yield per area, but the plant spacing did not affect this characteristic. Manual pollination, using a whole anther, did not differ from natural pollination in relation to seed yield and quality.

Tuberose (Polianthes tuberosa L.) is a perennial summer flower grown by smallholders in Kenya for export. However, its production and export volumes have declined drastically due to nematodes infestation. This study evaluated the effect of Cleome gynandra accessions on nematode management on tuberose. Experiment was conducted at the Horticulture Research Field, Egerton University, Kenya using a randomized complete block design with four replications. The treatments were: five accessions of C. gynandra namely ‘Simlaw’, ‘Egerton’, ‘Taastrup’, ‘PS’ and ‘IP8’, applied at 6 kg/m2 and compared with Brassica napus, solarization and untreated control. Data was collected on growth and yield parameters, nematode infestation and quality of tuberose. Data collected was subjected to analysis of variance at p≤0.05 and means separated using Tukey’s test. Biofumigation with Cleome gynandra accessions helped to reduce nematode population by 34%, gall numbers by 83% and galling index by be 96% when compared with the control. Use of biofumigation helped to improve plant height and leaf number of tuberose by 16% and 87%, respectively, when compared with the control. Use of biofumigation helped to improve spike length by 32%, marketable spikes by 80%, and flower yield by 90% and reduced nonmarketable spikes by 95% when compared with the control. Based on the above results, use of Cleome gynandra accessions and other biofumigants such as rape seed can be used to manage nematodes and improve growth, yield and quality of tuberose.

A two years field study was carried out in the research field and laboratory of Seed Technology Division, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during rabi season of 2008-10. The aim of this study was to determine the effect of five different dates of harvest viz. H1: 65 Days after emergence (DAE), H2: 70 DAE, H3: 75 DAE, H4: 80 DAE and H5: 85 DAE on the seed yield and viability of French bean. The experiment was laid out in randomized complete block design (RCB) with four replications. Results showed that the yield and yield contributing parameters significantly influenced the days to harvesting. The highest seed yields of 1.15 and 1.31 t ha-1 were obtained from the harvest of 75 DAE (Days after emergence) in 2008-09 and 2009-10, respectively. On the contrary, seed quality parameters like seed germination, root length and vigour index were also significantly influenced by harvest time. The highest seed germination percentage of 91.33 and 91.56 were recorded from the seed plots harvested at 75 DAE (pods are light brown with few yellow colour) both for the year 2008-09 and 2009-10, respectively. Similarly, the vigour indexes (12.49 and 11.64) were the highest in seed harvested at 75 DAE from the year of 2008-09 and 2009-10, respectively. This might be due to more food reserve and dry matter accumulation on the seed at later harvest. However, seeds harvested in 80 and 85 DAE were also found good for seed yield and seed quality.SAARC J. Agri., 13(1): 1-13 (2015)

This study was conducted for two seasons from 2018 to 2020 to determine fenugreek genotypes yield and quality characteristics under semiarid climatic conditions. Fenugreek genotypes viz., Adana, Afghanistan, Gaziantep, Iraq, Kahramanmaraş, Kayseri, Mardin, Şanlıurfa with varieties of Berkem and Gürarslan were used as plant material in the research. Field trials were conducted with four replications according to the randomized complete block design. The results revealed that the time to emergence varied from 16.0 to 19.9 days, 50% flowering from 160.9 to 170.4 days, and the vegetation period from 202.0 to 209.3 days. According to the results of two years of research, plant height varied from 64.60 to 78.70 cm, first pod height from 25.26 to 41.76 cm, pod width from 2.91 to 3.29 mm, pod length from 10.07 to 12.60 cm, number of pods per plant from 12.00 to 18.73, number of seeds per pod from 12.55 to 15.55, biological yield from 5.12 to 7.62 t/ha−1, seed yield from 0.91 to 1.38 t/ha−1, harvest index from 17.91 to 24.35%, thousand-seed weight from 13.87 to 17.45 g, fatty oil content from 5.18 to 9.16%, fatty oil yield from 49.3 to 111.6 kg ha−1, and the trigonelline ratio varied from 0.71 to 1.32%. Statistically significant differences (p ≤ 0.05) were observed for the pod width, while highly significant differences (p ≤ 0.01) were observed for all other parameters. According to the research results, Mardin, Kayseri, and Adana genotypes were statistically in the same group with Berkem cultivar in terms of seed yield. A higher fatty oil content was obtained in the Afghanistan genotype (9.16%) than in the Berkem cultivar (8.11%). Gaziantep, Mardin, Şanlıurfa, and Kayseri genotypes contained higher trigonellin than the Berkem and Gürarslan varieties. The obtained information was the result of the Mardin, Kayseri, Adana, Gaziantep, and Afghanistan genotypes that can be used in breeding studies.
