An experiment was conducted in the research field of Pulses Research Sub-Station, BARI, Gazipur during two consecutive years of 2015-16 and 2016-17 to determine the suitable dose of potassium for achieving higher yield attributes, nodulation, nutrient concentration and yield maximization of lentil. There were 5 treatments viz. T1 = Control, T2 = 30 kg K ha-1, T3= 40 kg K ha-1, T4= 50 kg K ha-1 and T5= 60 kg K ha-1 along with the blanket dose of fertilizers of N, P, S, Zn and B @ 15, 20, 10, 2 and 1.5 kg ha-1, respectively for all treatments. The experiment was laid out in randomized complete block design (RCBD) with three replications. Results revealed that the highest seed yield (1092 kg ha-1) of lentil (mean of two years) was found in T4 followed by T5 treatment and the lowest (736 kg ha-1) was noted in K control (T1) treatment. The highest % yield increase over control (48.3%) was recorded from T4 treatment. The maximum nodulation was found in T5 followed by T4 treatment. The highest protein (26.9%), N, P, K, S, Zn and B concentrations of lentil seed were recorded in T4 treatment. Therefore, the results suggest that the appliction of 50 kg K ha-1 along with N15P20S10Zn2B1.5 kg ha-1 are optimum for achieving higher yield potential of lentil in terrace soils of Bangladesh.

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 field experiment was carried out at the Soil Science research field of Sher-e-Bangla Agricultural University (SAU), Dhaka-1207, Bangladesh to study the nutrient uptake of sesame plant and available nutrient condition of soil after harvesting of sesame. Sesame variety BARI Til-3 was used as test crop. The experiment consisted of two factors. Factor A: Nitrogen levels (N0-3): N0: 0 kg N/ha (control), N1: 50 kg N/ha, N2: 60 kg N/ha, N3: 70 kg N/ha; Factor B: Boron levels (B0-2): B0: 0 kg B/ha (control), B1: 2 kg B/ha, B2: 3 kg B/ha. The experiment was carried out in two factors Randomized Complete Block Design (RCBD) with three replications. From the study, it was found that nutrient uptake of sesame plant and the nutrient concentration in post-harvested soil such as total N, available P, exchangeable K, available S and available B was increased with the increasing of nitrogen up to a certain level and boron supply. For the combined application of nitrogen and boron (60 kg N/ha and 3.0 kg B/ha) was found suitable to uptake maximum N, P, K, S and B by the sesame plant and to available the highest nutrient concentration in post-harvested soil.

Abstract: The objective of this work was to evaluate the effects of fertilization with nitrogen topdressing and silicates, as well as of the use of fungicides, on the occurrence of rice blast on panicles, milling yield, and whole grains, vitreous grains, and chalky kernels in a flood-irrigated rice cultivar sensitive to the disease. Two experiments were conducted in a randomized complete block design, in a 4×4×2 factorial arrangement, with four replicates: in experiment 1, four doses of nitrogen × four doses of calcium and magnesium silicate on soil × with and without fungicides; and, in experiment 2, four doses of nitrogen × four doses of potassium silicate applied on leaves x with and without fungicides. At the doses above 60 kg ha-1 nitrogen without fungicides, there was an increase of rice blast severity on panicles, a decrease in the percentage of whole and vitreous grains, and an increase in chalky kernels and chalky area. The greatest effects of silicates occurred without fungicides. Fungicide use reduced the severity of rice blast on panicles. Milling yield ranged from 60 to 70% in both experiments. The control of rice blast with fungicides maintains high rice grain quality, milling yield, and percentages of whole and vitreous grains.

Aim: To assess the residual effect of silicon (Si) and phosphorus (P2O5) application on the growth, productivity, lodging resistance and grain quality of wheat in Indo-Gangetic Plains of India. Methodology: A field experiment was conducted with four levels each of silicon (0, 40, 80 and 120 kg Si ha-1) and phosphorus (0, 30, 60 and 90 kg P2O5 ha-1) in a factorial randomized block design (FRBD) replicated three times at research farm of the ICAR-Indian Agricultural Research Institute, New Delhi during 2015-16 and 2016-17 to study the residual effect of Si and P2O5 on wheat. Growth, yield, yield attributes, lodging and grain quality parameters were analyzed using standard procedures. Both the nutrients were applied in aerobic rice crop and their residual effect was studied in wheat crop. Results: Application of Si and P2O5 in preceding rice crop significantly improved the growth, yield, grain quality of succeeding wheat crop. Grain yield of wheat was increased by 21% due to application of Si and P2O5. Significant improvement was observed when P2O5 and Si were applied at 60 and 80 kg ha-1, respectively. Lodging was reduced by 100% with P2O5 and Si application at 90 and 120 kg ha-1, respectively. Interpretation: Application of Si and P2O5 has potential to enhance productivity by improving growth, yield attributes and reduction in abiotic stress like lodging. Fertilization with P2O5 and Si can reduce lodging and improve wheat grain quality through enhanced sturdiness and protein content.

ABSTRACT For the implantation of a coffee tree crop, aiming at a high yield, each cultivar, depending on the plant distribution and density, can express differently its results. This study aimed to evaluate the yield potential and grain quality of Arabica coffee cultivars grown under different spacings between rows and between plants. A randomized block design was used, with three replications, in a split-split-plot scheme, being the plots three coffee cultivars (Obatã IAC-1669-20, Tupi IAC-1669-33 and Catuaí Vermelho IAC-144), four spacings between rows (1.8 m, 2.0 m, 2.5 m and 3.0 m) and four spacings between plants in the row (0.5 m, 0.7 m, 0.8 m and 1.0 m), totaling 48 treatments. The type of coffee bean (flat, peaberry and elephant) and yield per hectare were evaluated. The Obatã cultivar showed the highest potential yield, in relation to Tupi and Catuaí Vermelho, and also the highest percentage of flat grains. The factors, in order of importance, that interfere with the potential yield of processed coffee are the cultivar and the spacing between rows and between plants.

Genetic background, environmental conditions, and agronomical practices could influence yield components, grain quality, and physicochemical properties of rice. The study aim was to investigate the variations in yield potential, quality traits, and morphological observation among Akitakomachi (japonica), IR-28 (indica), and NERICA-4 (hybrid) varieties under the same environmental and agronomical conditions. For this, the cultivars were compared in a randomized complete block design with three replications at the paddy field of Tsukuba International Center, JICA, Tsukuba, Japan in 2017. All cultivars were transplanted at a spacing of 15×30 cm using three seedlings per hill. The results exhibited that Akitakomachi had a higher number of panicles per m2 (344.3), and the ripening ratio (94.3%) across all cultivars. In addition, IR-28 and Akitakomachi achieved significantly higher rough rice yield (6.9 t/h & 6.1 t/h), respectively, compared to NERICA-4 (4.9 t/h). However, NERICA-4 was associated with the significantly higher amylose and protein contents, which resulted in the reduction of the taste point than other cultivars. Furthermore, the lowest grain transparent (34.2%) and highest chalky grain (47.7%) were obtained in NERICA-4, which leads to lower grain quality. IR-28 and NERICA-4 were classified as long and slender grain types, whereas, Akitakomachi as a short and medium grain, respectively. The micrographs observation displayed that regular starch granules with polyhedral shape were arranged without air gaps in transparent grains of all cultivars. In contrast, the endosperm of chalky grains in NERICA-4 and IR-28 revealed that irregular starch granules with round shape were loosely packed. Thus, each cultivar should be considered based on growing regions and the cultivated aims.

Products with physiological effects on plants to optimize agricultural production is increasingly used; they can change the development of plants and the chemical characteristics of seeds. The objective of this work was to evaluate the development of soybean cultivars and the protein and oil contents of soybean grains after treatment with pyraclostrobin and biostimulant. The experiment was carried out with soybean crops without irrigation. The experimental design was a randomized complete block design, with five replications, using a 3 × 3 factorial arrangement consisting of three cultivars of different maturation times (very early, M6952IPRO; early M7739IPRO; and medium, ST797IPRO), and three treatments with products that cause physiological effects (control, pyraclostrobin, and control + biostimulant). The pod, leaf, and stem dry weights, number of pods, 100-grain weight, grain yield, and oil and protein contents of the soybean plants were evaluated. The data were subjected to analysis of variance, and Tukey’s test at 5% probability. The effects of the products used (pyraclostrobin and biostimulant) vary according to the cultivar and may increase the soybean leaf and pod dry weights, and grain protein contents.

Boron deficiency drastically affects the yield and quality of many crops especially maize. The low availability of boron in soils is one of the major causes of poor quality and low yield of maize in Pakistan. A wirehouse experiment was carried out at Department of Crop Physiology, University of Agriculture, Faisalabad to optimize the dose of boron to increase quality and yield of maize. Two recommended local maize hybrids Monsanto-919 and Monsanto-5219 were evaluated in a randomized complete block design with factorial arrangements. The Boron was applied as borax @ 0, 0.3, 0.6, 0.9, 1.2 and 1.5 kg ha¯¹ at tasseling stage. Although both hybrids showed non-significant differences in yield attributes exogenous boron supply @ 0.6 kg boron ha¯¹ increased grain yield by 27% as compared to control treatment in both the hybrids. It increased grain oil, protein and starch contents by 10%, 12% and 16% respectively.

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.

Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.
