Crop management like planting time is a crucial factor for maximizing yield especially for seed production. Seed production of carrot is greatly influenced by temperature as it requires adequate periods of cool temperature (vernalization) for flowering and seed production. To find out optimum planting time of carrot steckling for quality seed production the experiment was conducted at the Field Laboratory of Horticulture Farm, Bangladesh Agricultural University, Mymensingh during the period from October 2015 to May 2016.Three planting time viz. 05 January, 15 January and 25 January on the seed production of three carrot varieties viz. BA (Brasillia Agroflora), PA (Prima Agroflora) and NK (New Kuroda) which constituted 9 treatment combinations were included in the experiment. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Planting time had significant effect on most of the parameters studied. The January 05 planting of steckling gave the highest seed yield (527.92 kg ha-1) and the lowest was in January 25 planting of steckling (314.75 kg ha-1). Among the varieties BA gave the highest seed yield (448.73 kg ha-1) and the lowest yield for New Kuroda (395.35 kgha-1.) Considering interaction of planting time and variety the highest seed yield (572.37 kg ha-1) was obtained from the treatment combination of early planting (05 January) with the variety of BA and the lowest (279.77 kg ha-1) was recorded from the late planting (25 January) in variety PA. Hence, BA carrot variety planting on 5 January may be recommended for carrot seed production in Mymensingh region in Bangladesh. Bangladesh Agron. J. 2020, 23(2): 23-34

An experiment was conducted at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during October 2006 to May 2007 to evaluate the effects of zinc, boron, and molybdenum on the seed yield of carrot. The soil of the studied field was deficient in zinc, boron, and molybdenum and represents Salna Series of Shallow Red Brown Terrace under Madhupur Tract (AEZ-28). Four (4) levels each of zinc (0, 2.0, 4.0, and 6.0 kg/ha), boron (0, 1.0, 2.0, and 3.0 kg/ha) and molybdenum (0, 0.5, 1.0, and 1.5 kg/ha) were used to formulate 11 treatment combinations to observe their effects on the seed yield of carrot (cv. Bejo Shetal). A blanked dose of N120P54K150S20 kg/ha was also applied to nourish the crop. The experiment was laid out in a randomized complete block design with three replications. The seed yield of carrot was significantly increased due to integrated effects of zinc, boron and molybdenum. The highest seed yield (362.28 kg/ha) was found with Zn4.0B2.0Mo1.0 kg/ha combination, which was 283% higher over control. The maximum germination percentage (91.30) and vigor index (4.99) of seed was also recorded from the same treatment package and thus may be recommended for the production of carrot seed in the studied or alike area of the country.

Aim: The objective of this study is to identify the suitable planting method and seeding time for leaf and seed production of lettuce. Place and Duration: A field study was carried out in Bangadandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur Bangladesh during 2012-13. Materials and Design: A commercial lettuce variety BSMRAU lettuce-1 was used in this study. The experiment was laid out in a randomized complete block design with three replications and two factors, namely planting method (M1 – transplanted seedling produced on nursery bed, M2 - transplanted seedling produced in polybag and M3 - direct seeding) and seeding time (T1 - 16 October, T2 - 1 November, T3 - 16 November, T4 - 1 December and T5 - 16 December). Results: Analyses of variance revealed with a statistically significant variation (p<0.01 or p<0.05) among the treatments. The treatment interaction revealed that the highest leaf yield 27.33 t/ha was harvested from M3T2, which was statistically similar with M2T2 (26.78 t/ha). On the other hand, the highest seed yield 412.00 kg/ha was harvested from the treatment combination of M3T2, which was statistically different from all other treatment combinations. Quality traits viz. dry matter content, fiber content and organoleptic test were also better in early seeding. Conclusion: Considering leaf yield, seed yield and quality traits, direct seeding at 1 November was found to be the most suitable treatment combination for leaf and seed production of lettuce in Bangladesh conditions. But transplanting with polybag raised seedlings may be suitable if the land is occupied by the pervious crops.

The quality of seed needs to be considered in carrot seed production to maintain its productivity. The research aims to find out the response of stecklings age and plant spacing on carrot seed quality and production. This research was held on July 2018 – April 2019 in Berastagi field trial (1340 m MSL). The experiment used Randomized Complete Block Design (RCBD) with two factors, i.e., stecklings age (2 and 3 months) and plant spacing (25, 50, 75, and 100 cm), replicated four times (32 experiment units), 10 plants from each experiment units were taken as samples. The result showed that stecklings age and plant spacing were affected to plant vegetative and generative stages. The combination of 2-month stecklings and 50 cm plant spacing increased the number of secondary umble, if compared to cultivation, which was generally used by the farmer (3-month stecklings and 25 cm plant spacing). The best quality of carrot seed was obtained from the combination of 3-month stecklings and 50 cm plant spacing.

An experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2017 to April 2018. The present research was aimed to study effect of combinations of zinc and boron with fruit thinning on the quality seed production of tomato. There were four combination of zinc and boron viz. T0 =Zn0 kgB0kg/ha, T1=Zn2 kg B1.5 kg/ha, T2=Zn4kg B2 kg/ha, T3=Zn6B2.5 kg/ha and four levels of fruit thinning viz. P0= control (without fruit thinning), P1= 10 fruits were retained per plant, P2=20 fruits were retained per plant and P3 =30 fruits were retained per plant. The experiment was laid out in a Randomized Complete Block Design with 3 replications and there were altogether 48 plots. Application of micronutrients with fruit thinning significantly influenced the growth and seed yield of tomato. The highest seed yield (297.82 kg/ha) was found from T3 and the lowest yield (260.69 kg/ha) was obtained from T0. Due to the fruit thinning, the highest seed yield (337.41 kg/ha) was obtained from P3 and lowest yield (190.69 kg/ha) was recorded from P1. In case of combined effect, the highest yield (360.39 kg/ha) was found from T3P3 and lowest yield (180.39 kg/ha) was found from T0P1. So, application of Zn6 kg B2.5 kg/ha along with 30 fruits were retained per plant was the best for yield of tomato seed.

Plant Densities

Optimal plant density is required to improve plant phenological traits and maximize seed yield in field crops. In this study, we determined the effect of plant density on duration of flowering, post-flowering phase, and seed yield of canola in diverse environments. The field study was conducted at 16 site-years across the major canola growing area of western Canada from 2010 to 2012. The cultivar InVigor® 5440, a glufosinate-resistant hybrid, was grown at five plant densities (20, 40, 60, 80, and 100 plants m−2) in a randomized complete block design with four replicates. Canola seed yield had a linear relationship with plant density at 8 of the 16 site-years, a quadratic relationship at 4 site-years, and there was no correlation between the two variables in the remaining 4 site-years. At site-years with low to medium productivity, canola seed yield increased by 10.2 to 14.7 kg ha−1 for every additional plant per square metre. Averaged across the 16 diverse environments, canola plants spent an average of 22% of their life cycle flowering and another 27% of the time filling seed post-flowering. Canola seed yield had a negative association with duration of flowering and a positive association with the days post-flowering but was not associated with number of days to maturity. The post-flowering period was 12.7, 14.7, and 12.6 d (or 55, 68, and 58%) longer in high-yield experiments than in low-yield experiments in 2010, 2011, and 2012, respectively. We conclude that optimization of plant density for canola seed yield varies with environment and that a longer post-flowering period is critical for increasing canola yield in western Canada.

An experiment was conducted at the Sher-e-Bangla Agricultural University farm from April to June 2017 in Kharif season to evaluate the performance of two mungbean varieties under different NPK fertilizers doses in field conditions. The experiment was laid out in Randomized Complete Block Design (RCBD), comprising six treatments with three replications. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the combination of the treatment were T0 = (control), T1 (10-40-25 NPK kg ha-1), T2 (10-60-45 NPK kg ha-1), T3 (20-50-35 NPK kg ha-1), T4 (30-40-25 NPK kg ha-1) and T5 (30-40-45 NPK kg ha-1), respectively. Mungbean cultivars responded noticeably to the supplementary NPK fertilizers as the crop characters were significantly influenced by different levels of NPK fertilizers. Data were recorded on plant height, leaves plant-1, branches plant-1, pods plant-1, seeds pod-1, 1000-seed weight, seed, and straw yield at different days after sowing. Of the two varieties, BARI mung-6 gave the highest seed yield (1.72 t ha-1) next to the higher plant growth and straw yield On the contrary, BARI mung-5 cultivar produced the lowest seed yield (1.57t ha-1), plant growth, and straw yield. The results showed that T3 (20-50-35 NPK kg ha-1) treatment was the best treatment as regards plant growth and yield parameters. The highest seed yield was produced by treated plot T3 (20-50-35 NPK kg ha-1) over the untreated control plot, T1, T2, T4, and T5, respectively. As for the combined effect, V1T3 (BARI mung-6 and T3 = 20kg N + 50kg P + 35kg K ha-1) performed the best results in all growth and development characters. Therefore, the combined application of 20-50-35 kg NPK ha-1 might be considered to be found optimal to get a considerable seed yield of mungbean variety BARI mung-6.

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.

Study was conducted in 2006 and 2007 cropping seasons at the experimental field of Federal University of Technology, Minna (9o 401N and 6o 301E), in the Southern Guinea Savanna of Nigeria to determine the effects of N fertilizer and the fruit positions on fruit and seed yield of okro. The treatment comprised factorial combination of five nitrogen levels (0, 30, 60, 90 and 120 kg/ha) and five fruit positions on a mother-plant (3, 5, 7, 9 and 10) which were replicated three times and laid in a Randomized Complete Block Design (RCBD). The results indicated that significant taller plants were recorded in the plots that received 120 kg N/ha while shorter plants were recorded in plots that received 0 N/ha in both years of the study. The higher N level of 120 kg/ha and lower fruit position of 3 significantly gave higher number of fruit yield while the yield decreased with decrease in N level and increase in fruit position on the mother-plant. Similarly, heavier fruits were recorded in lower fruit positions and higher N levels. The fruits formed at the lower position 3 and 5 produced more seeds with higher seed weight than those formed at the higher positions. The results also showed that significantly higher seed yield was recorded at N level of 120 kg/ha ?.

Abstract In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress, iron spray on the yield and yield components of corn, an experiment was carried out during the crop seasons of 2013 on research Farm in Faizabad of Iran, as a split plot within randomized complete block design with three replications. The main plots with irrigation factor and four levels were considered: level A) 50 ml evaporation from pan evaporation; level B) 100 ml evaporation from pan evaporation; level C) 150 ml evaporation from pan evaporation and level D) 200 ml evaporation from pan evaporation. Sub plots were considered with iron spray in three levels, included level A) 80 g/ha, level B) 130 g/ha and level C) 180 g/ha. The drought stress reduced seed yield, the 1000-kernels weight (TKW), the number of seeds per ear, the number of seeds per row in ear, the number of rows per ear about 39%, 6%, 31%, 14% and 27% less than control treatment, respectively. Using iron, as compared with control treatment, causes the increase of 1000-kernels weight from 295 to 311 g and the increase of seed yield from 5188 to 7078. The results obtained from the present research showed that iron spray has fairly improved the effects caused by drought stress.

Sesame (Sesamum indicum. L) is one of the main sources of livelihoods in northern Uganda. However, its production is constrained by low soil fertility and moisture levels. A study was conducted at Serere, Uganda in 2013 and 2014 to investigate the effect of organo-mineral fertilizers on growth, seed yield and nutritional quality of sesame. The design of the experiment was a randomized complete block design with three replications. The treatments comprised: control (no soil amendment), mixtures of 4 crop residues each at (3 and 6 t/ha) and two rates of N, P and K. Finger millet husks (3 t/ha) plus lower fertilizer rate (30 kg N-25 kg P-40 Kg K/ha) had significantly higher seed yield of sesame; while finger millet husks (6 t/ha) plus higher fertilizer rate (60 kg N-50 kg P-80 Kg K/ha) significantly increased vegetative growth of sesame. Finger millet husks (6 t/ha) plus lower fertilizer rate had significantly higher seed crude protein content of sesame; while cowpea husks (3 t/ha) plus higher fertilizer rate and groundnut shells (3 t/ha) plus lower fertilizer rate produced significantly higher seed total ash and seed oil content of sesame, respectively. This study has demonstrated that application of a mixture of crop residues and inorganic fertilizers is the best treatment in enhancing growth, seed yield and nutritional seed quality of sesame.
