Zinc Application

Zero or no tillage (ZT) mustard (Brassica campestris L.) cultivation is being increased and popularized these days in Bangladesh. But micronutrient management specially Zinc (Zn) with recommended dose of NPKSB fertilizers are poorly practiced in this type of cultivation. Micro nutrient deficiency is an emerging problem due continuous usage of soil resources (ground water, intensive cultivation etc.). Thus, to sustain and adopt the potential yield of modern mustard varieties all types fertilization is must. Basing on this problem an investigation was employed at Bangladesh Institute of Nuclear Agriculture (BINA) Sub-station, farm, Ishurdi, Pabna to find out definite dose of zinc application under zero tillage mustard cultivation for maximizing seed yield. The study was laid in a factorial Randomized Complete Block Design (RCBD) with three replicates. Two modern varieties viz. Binasarisha-10 (V1) and BARI Sarisha-14 (V2) were tested with six level of Zn doses viz. 0.0 kg ha-1 (T1), 1.5 kg ha-1 (T2), 3.0 kg ha-1 (T3), 4.5 kg ha-1 (T4), 6.0 kg ha-1 (T5) and 7.5 kg ha-1 (T6). Seed were line broadcasted after harvesting T. aman rice during Rabi 2020 season. Data on yield parameters were collected after final harvesting and analyzed by Statistix 10. Results divulge that maximum straw and seed yield was attained with treatment combinations V1T4 (3.63 t ha-1) and V2T4 (2.24 t ha-1) with V2T3 (2.18 t ha-1). Whereas, the minimum was obtained from V2T5 (2.51 t ha-1) and V1T1 (0.99 t ha-1) along with V2T1 (1.01 t ha-1). Hence, soil application of Zn between 3 kg ha-1 to 4.5 kg ha-1 may give satisfactory yield for ZT farming.

In severely deficit soil, lentil (Lens culinaris Medic) crop requires micronutrients for increased production. Micronutrient management is, therefore, very important for lentil productivity but mostly ignored. This study was carried out from 2014–2015 to 2016–2017 to understand the effects of zinc (Zn), boron (B), and molybdenum (Mo) on lentil productivity, nodulation, and nutrient uptake and how these elements improve soil micronutrient fertility. The experiment was laid out in randomized complete block design, and the treatments were replicated thrice. Different combinations of Zn, Mo, and B were contrasted with no application of micronutrients. The treatments were Zn alone (Zn), B alone (B), Mo alone (Mo), Zn combined with B (ZnB), Zn with Mo (ZnMo), B with Mo (BMo), and Zn combined with B and Mo (ZnBMo). Doses of Zn, B, and Mo were 3, 2, and 1 kg ha−1, respectively. In this trial, the highest average seed yield (1807 kg ha−1) and yield increment (44%) was obtained in ZnBMo combined application with macronutrients. Single, dual, and combined application of Zn, B, and Mo had significant effects on yield parameters and yield of lentil (P < 0.05). The highest nutrient uptake, maximum nodulation (63.5 plant−1), and the highest protein content (26.6%) in seed were recorded from the treatment receiving all three micronutrients. The increased lentil yield might be associated with increased nodulation and nutrient uptake by the crop under micronutrient-applied treatments. The results suggest that combination of Zn, B, and Mo could be applied for increased lentil production in micronutrient deficit soils.

The field experiment was carried out during winter of 2018/19 with two varieties (Unnati and Surkhet-Local) and three plant geometry (15cm × 10 cm, 30cm × 10 cm, 45cm × 10cm) in Randomized complete block design (RCBD) with four replications. Statistically there was no difference between two varieties while differences were found on different spacing and interaction between variety and spacing on final seed yield. High significant differences on seed yield was due to spacing and yield of rapeseed were higher at the 30 cm inter row spacing as compared to the 15 cm and 45 cm inter row spacing. Statistically significant effect was found on mean values of seed yield for interaction which showed that Unnati cultivar in 30 cm x 10 cm plant geometry had the highest seed yield (969.86 kg/ha) followed by Surkhet-local with  spacing of 15 cm × 10 cm (843.75 kg/ha) and 30 cm × 10 cm (823.76 kg/ha). Yield of these varieties decreased as spacing is increased, thus sowing of Unnati should be done at cropping geometry of 30 cm × 10 cm and for Surkhet-local it should not be done beyond 30 cm inter row spacing to get the maximum potential yield.

In the cropping year 2013-2014, a split plot experiment using the randomized complete block design with three replications was conducted in a field in Pol-e Dokhtar in Lorestan Province to study the effects of planter type and seeding rates used in direct and customary planting practices. Results showed there were significant differences between planters with respect to percentage of broken seeds at the 1% level. Comparison of the means indicated the highest percentage of broken seeds (5.1%) belonged to the Barzagar-e Hamadani planter and the lowest to the Gaspardo and Sfoggia direct planters. Type of planter also influenced precision in longitudinal distance at the 5% level. Moreover, comparison of the means revealed that the best uniformity in appropriate longitudinal distance between seeds in planted rows was that of the Gaspardo and Sfoggia direct planters and the worst that of the Barzegar-e Hamadani planter and that the effects of various planters were significant at the 5% level. The Gaspardo and Sfoggia direct planters, with 88.26 and 86.49%, respectively, had the maximum uniformity in depth of planting, and the Barzegar-e Hamadani with 79.03% the minimum. ANOVA suggested the various planters were not significantly different in wheat yield, while the effects of seeding rate treatments on wheat seed yield were significant at the 5% level. Nevertheless, comparison of the means showed that the Gaspardo direct planter raised seed yield by 1.32 and 11.13% compared to the Sfoggia direct planter and the Barzegar-e Hamadani planter, respectively, and that it enjoyed relative superiority over them. Moreover, comparison of the means related to seeding rates indicated the 200 kg/ha rate increased seed yield by 11.05 and 24.36%, respectively, compared to the 160 and 240 kg/ha rates. Results of this research suggested direct planting with the Gaspardo planter at the seeding rate of 200 kg/ha achieved maximum seed yield. Therefore, this combination was recommended for the region.

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.

Finger millet is a climate compliant crop; its production remains low due to poor establishment methods. A field experiment was conducted during the rainy season of 2018/19 at Dorcas Charare plot in ward 24, Zaka district to investigate the effects of establishment methods on yield and yield parameters of finger millet (Eleusine coracana L. Gaertn). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three treatments namely broadcasting, hand drilling and transplanting replicated three times. Results on grain yield showed that transplanting method had the highest yield of 0.51t/ha whilst drilling and broadcasting scored 0.40t/ha and 0.35t/ha respectively. Transplanting method significantly (p<0.05) influenced higher number of tillers (7.13) per hill followed by drilling (2.40) and lastly broadcasting (2.13). Significant differences (p<0.05) were noted on panicle number with transplanting scoring the highest (8.13) and broadcasting the lowest (3.13). It can be concluded from the study that transplanting method realized a higher panicle number, tiller number and grain yield. Farmers must adopt transplanting as an establishment method in finger millet production.
