Coriander Seed

A field experiment on coriander (Coriandrum sativum L.) was carried out during rabi seasons of 2011-12 and 2012-13 in Low Ganges River Flood Plain Soil under AEZ-12 at Farming System Research and Development Site, Hatgobindapur, Faridpur to find out optimum and economic doses of fertilizers for coriander (var. BARI Dhania 1) for sustainable higher yield and to update balanced fertilizer recommendation for target yield. The experiment was laid out in a randomized complete block design with 8 treatments viz. T1=N118P47K26S10Zn2.2B0.8 Kgha-1, T2= N147P47K26S10Zn2.2B0.8 Kg ha-1, T3= N147P59K26S10Zn2.2B0.8 Kg ha-1, T4= N147P47K32S10Zn2.2B0.8 Kgha-1, T5= N118P59K32S10Zn2.2B0.8 Kgha-1, T6= N147P59K32S10Zn2.2B0.8 Kgha-1, T7= N88P35K19S8Zn1.6B0.6 Kgha-1 and T8= Native nutrient (Control). The highest seed yield (1373 kg ha-1) was obtained from the treatment T3 which was statistically similar with T1, T2, T3, T4, T5 and T6 treatments. The soil test based treatment T1 produced 1311 kg yield ha-1 and yield difference of ther added fertilizer treatment with T1 was only 5%. The fertilizer added treatments didn’t exert the significant difference with soil based treatment (T1) on yield and yield contributing characters. However, T1 treatment appeared to be the best suited combination because of its higher gross margin Tk 41,769 ha-1, capability in reducing nutrient cost Tk 13106 ha-1 and the highest marginal rate of return (MRR) (108%) whereas treatment T3 covered 21% MRR and the highest nutrient cost among the treatments and hence treatment, N118P47K26S10Zn2.2B0.8 Kg ha-1 (100% NPKSZnB from STB dose) may be recommended for coriander seed production in the study area.Bangladesh J.

The experiment was carried out in the Surma Kushiyara Floodplain soil at the farmer’s field of Farming System Research and Development (FSRD) site, Jalalpur, under South Surma Upazilla of Sylhet district in the medium high land under agro-ecological zone (AEZ)-20 for the three consecutive years 2013-2016 to determine economic dose of organic and inorganic fertilizers for Potato-T. aus -T. aman rice cropping pattern. The experiment was composed of four treatments viz. T1: Soil test based (STB) fertilizer dose for high yield goal (HYG), T2: T1+ CD 5 t ha-1, T3: T1 along with CD 5 t ha-1 in IPNS approach and T4: Farmers practices for potato-T. aus -T. aman rice cropping pattern maintained in a randomized complete block design with six dispersed replications. The varieties for potato, T. aus and T. aman rice were Diamont, BRRI dhan48 and Binadhan-7, respectively. The results showed that the tuber yield of potato, grain yields of T.aus and of T. aman rice were significantly influenced by the different treatments. The increase yield of tuber 6.11t ha-1 (33.30 %), grain of T. aus 0.42 (10.24%) and T. aman 0.54 (15.52%) rice was obtained from T2 over control (T4) and also higher compared to other treatments. The treatment STB fertilizer for HYG + 5 t ha-1 of CD also showed 25.03% higher T. aman rice equivalent yield (22.53 t ha-1) compared to farmers practice (T4) treatment. The monetary values for the whole cropping pattern showed that the highest benefit cost ratio (2.03), gross return (Tk. 4,61,865 ha-1) and gross margin (Tk.2,33,735 ha-1) were obtained from STB fertilizer for HYG + 5 t ha-1 of CD. The treatment IPNS based on fertilizer management with cowdung for HYG had no significant effect on the yield of first and succeeding crops. So, considering crop productivity and economic return, soil test based fertilizer for high yield goal with 5 t ha-1 cowdung could be recommended for the Potato - T. aus - T. aman rice cropping pattern for AEZ-20 of Sylhet region.Bangladesh Agron.

Planting with a lane system in palm sugar and cacao plants is a technique of plantation cultivation that aims at soil conservation and microenvironment. Plant cultivation in the field needs to get a supply of fertilizer to increase crop productivity. This study aims to determine the effect of giving SP-36 and KCl fertilizer to the best growth of sugar palm and cacao plants in the planting of path systems. The research was conducted on land in Badak Mekar Village, Muara Badak District, Kutai Kartanegara Regency, East Kalimantan. The research method used a Randomized Block Design (RBD) and repeated 4 times. Factorial experiments consisted of 2 factors, as the first factor was SP-36 fertilizer (p) consisting of 3 levels: p0 = 0 kg plant-1 (control); p1 = 0.25 kg of plant-1; p2 = 0.5 kg of plant-1. The second factor was KCl (k) fertilizer consisting of 3 levels: k0 = 0 kg plant-1 (control); k1 = 0.25 kg of plant-1; k2 = 0.5 kg of plant-1. The variables observed included: (1) Arenaceous plants: increase in caudal circumference, increase in the fifth midrib length, increase in the number of midribs, increase in number of leaflets on the fifth midrib and (2) Cocoa plants: increase in plant height, increase in stem circumference, the number of cocoa fruits, the intensity of pest and disease attacks on cocoa fruit. Observations on each variable were carried out at 3 and 6 months after treatment (mat). Data were analyzed by variance and if there were significant differences, it was followed by the Smallest Significant Difference Test (LSD) at the level of 5%. The results of the SP-36 fertilizer treatment showed very significant differences in all observation variables in early maturing palm trees and aged 3 bsp and 6 bsp cacao plants. The treatment of SP-36 fertilizer at a dose of 0.5 kg plant-1 (p2) gave the best growth of early maturing sugar palm plant 6 in the increase of the fifth midrib length, increase in bulb circumference, increase the number of midribs and increase the number of leaflets on the fifth midrib - each 137.17 cm, 25.58 cm, 3.25 strands and 39.08 strands. Likewise in the age of 6 bsp cocoa plants SP-36 fertilizer with a dose of 0.5 kg plant-1 (p2) gave the best growth in plant height increase, increase in stem circumference and number of cocoa fruit, each 18.92 cm, 8.25 cm and 25.25 pieces. The treatment of KCl fertilizer and the interaction between SP-36 and KCl fertilizers showed no significant difference in all observation variables in early maturing and cacao plants. Observations of pest and disease attacks on cocoa fruit with the intensity of pest attacks 0.00-23.47% were included in the category of minor damage and the intensity of disease attacks 0.00-66.30% which fall into the category of moderate damage.

The field experiment was conducted during the rabi season of 2005-06 in the farmer's field of Multi-location Testing (MLT) site, Melandah, Jamalpur to evaluate the performance of sweet potato varieties as well as to determine the optimum dose of fertilizer of sweet potato. Two varieties of sweet potato viz., i) BARI Sweet Potato-5 and ii) BARI Sweet Potato-7 and five fertilizer doses viz., i) Estimated fertilizer dose for average yield goal (EDI for average yield goal), ii) Integrated Plant Nutrient System (IPNS) basis fertilizer dose, iii) Fertilizer Recommendation Guide' 97, iv) Farmer's practice, and v) Control. The highest sweet potato yield was obtained from BARI SP-7 with (IPNS) basis fertilizer doses (33.9 t/ha). The lowest sweet potato yield was obtained from BARI SP-7 with control treatment. The highest gross return (112700 Tk./ha) and gross margin (10756 Tk./ha) was recorded from IPNS basis fertilizer treatment. The lowest gross return (40950 Tk./ha) and gross margin (40951) Tk./ha) was recorded from control treatment. But the cost and return analysis showed that the highest benefit cost ratio (24.95) and marginal rate of return (1452) was found from FRG/97 treatment due to lower additional cost.

Fertilizers and fertilization technology have important roles in increasing crop production including lowland rice. In response to the issue, a field experiment was conducted to study the effects of micronutrients on growth and yield of lowland rice. The experiment was carried out at Cihideung Ilir Village, Dermaga Sub-district, Bogor Regency from November 2015 until March 2016. The experiment consisted of 8 treatments, namely control (without fertilization), NPK-standard, NPK-standard  + ¼ dosage of Hortigro Rice fertilizer, and ¾ NPK  + ¼  until 11/4 dosages of Hortigro Rice fertilizer as a source of macronutrients N, P, K and micronutrients of Mn, Cu, Zn, B, and Mo. The treatments were arranged in a Randomized Block Design with 3 replications. Parameters observed during the research were plant height, tiller number, and yield of grain and straw of INPARI-32 lowland rice as crop indicator. The  results  showed that among other treatments, the highest plant height was resulted from the application of ¾ NPK-standard + ¼ Hortigro Rice, i.e. around 124 cm at 60 days after planting. The highest harvesting dry weight of grain and straw were observed in NPK-standard + 1/4 of Hortigro Rice fertilizer treatment, i.e. around 9.0 Mg ha-1 and 25.9 Mg ha-1, respectively. This yield showed a significant difference with ¾ NPK-standard combined with ¾  -11/4 dosages of Hortigro Rice. The highest  dry weight of  milled grains was  resulted in the application of  ¾ NPK-standard + 1/2 Hortigro Rice, i.e. around 7.3 Mg ha-1, which is significantly different from that in ¾ NPK-standard combined with 1.0 - 11/4 dosages of Hortigro Rice treatments, while the highest dry weight of straw was provided by NPK-standard, i.e. around 14.0 Mg ha-1. The highest  dry weight of 1000 milled grains and ratio of  dry weight of milled grain to straw were provided by ¾ NPK-standard + 1/2 Hortigro Rice around 32.0 gram and  0.63, respectively. The results indicated that the application of micronutrient fertilizer of Hortigro Rice in combination with NPK fertilizers can potentially increase lowland rice productivity due to the micronutrients content of Mn, Cu, Zn, B, and Mo in it.

This research design was used as a Randomized Block Design (RBD) consists of two factors with 4 replication. The first factor consisted of types of organic fertilizer (P) i.e. chicken manure (PA), guano manure (PG), and cow manure (PS). The second factor consisted of fertilizer dosage (D) i.e. 0 tons ha-1 (without fertilization, called control), D1 = 15 tons ha-1, D2 = 30 tons ha-1 and D3 = 45 tons ha-1. The data obtained by analysis of variance (ANOVA) or F test at a = 5% and 1% levels to determine the effect of treatment was tested further by HSD (honestly significant difference) testat the level of 5%. The result shows that the interaction type of organic fertilizer and the dosage of organic fertilizer treatment significant effect on the weight of the melon. Chicken manure is the best organic fertilizer on the size and quality of the melon. Dosage of 45 tons ha-1 organic fertilizer gave the highest results but it was not significantly different with a dosage of 30 tons ha-1. The use of chicken manure fertilizer of 30 tons ha-1 is more efficient in agronomy in increasing melons yield on peatlands.

A field study was carried out in a vegetable research field of the National Horticultural Research Institute, Ibadan, Nigeria during the late raining season of 2015 to determine the appropriate okra/legume-based cropping system that will increase crop yield and farmer?s income. The experiment was arranged in a randomized complete block design (RCBD) with three (3) replicates. The treatments comprised intercropping okra with groundnut or cowpea planted at varying spacings (60 cm x 30 cm, 60 cm x 40 cm, 60 cm x 50 cm and 60 cm x 60cm). Okra was planted at a spacing of 60 cm x 40 cm, the plot size was 3 m x 2.4 m (7.4 m2). Data collected was subjected to analysis of variance (ANOVA) and significant means were separated using the least significant difference (LSD) test at the 5% probability level. Economic analysis of the cropping mixture was carried out using gross margin analysis, monetary advantage index and benefit to cost ratio analysis. Results revealed that the land equivalent ratio (LER) of 1.62 was recorded in okra/groundnut at 60 cm x 40 cm and LER of 1.74 was observed in okra/cowpea at 60 cm x 30 cm. Okra/cowpea intercropping system spaced at 60 cm x 30 cm was the most remunerative (N859,192/ha), followed by okra/cowpea spaced at 60 cm x 50 cm (N744,212/ha) while okra/cowpea spaced at 60 cm x 60 cm was the least remunerative. The highest gross margin of N2,188,961/ha was obtained in okra/groundnut spaced at 60 cm x 40 cm. The least return was obtained in okra/groundnut spaced at 60 cm x 60 cm (N700,103/ha). The economic analysis revealed that okra/cowpea spaced at 60 cm x 30 cm produced the highest gross margin of N859,192/ha and monetary advantage index of N450,447/ha while okra/groundnut spaced at 60 cm x 40 cm gave the highest gross margin of N2,188,961/ha and monetary advantage index of N924,642/ha.

In order to evaluate the yield, yield components and some physiological and qualitative traits of corn treated with nitrogen fertilizers (biological, chemical and integrated), a field experiment was conducted at the Agricultural Research Station of Khorramabad during 2016 growing season. Treatments were arranged in a complete randomized block design with four replications. Experimental treatments consisted of 100% chemical fertilizer (urea), bio-fertilizer (nitroxin), integration of bio-fertilizer + 25% chemical fertilizer, integration of bio-fertilizer + 50% chemical fertilizer, integration of bio-fertilizer + 75% chemical fertilizer and the control. Results showed that the effect of different treatments of fertilizers on all measured traits, except for number of rows in each ear and carotenoids, was significant. The results indicated that integration of bio-fertilizer + 75% chemical fertilizer affected the highest grain yield (9.31 t ha–1), dry biological yield (20.96 t ha–1), number of kernels in each row (41.67), plant height (201.02 cm), hectoliter weight (0.82 g cm–3), chlorophyll b (0.43 mg g–1 FW), total chlorophyll (1.1 mg g–1 FW) and leaf area index (LAI) (4) and there was no significant difference among this treatment and 100% chemical fertilizer (N) and integration of bio-fertilizer + 50% chemical fertilizer treatments in all measured traits. The greatest harvest index (45.8) and grain protein-content (9.1%) resulted from the integration of biofertilizer+ 50% chemical fertilizer treatment. Also the highest 1000-grains weight (281.13 g) and chlorophyll a (0.66 mg g–1 FW) were caused by 100% chemical fertilizer (urea) treatments. Results showed that integration of bio-fertilizer + chemical fertilizer could be considered as a means to reduce the consumption of chemical fertilizers for sustainable agriculture.

Vermicompost is a nutrient-rich organic waste produced from earthworms that is beneficial in enhancing the soil condition and has been reported to aid in improving the crop yield and quality. In the present study, a field trial was conducted using a randomized complete block design with four replicates to elucidate the effects of vermicompost application (compared to supplementation with chemical fertilizer and no fertilizer) on the productivity of ex vitro MD2 pineapple plants. Vermicompost was applied on the sandy loam soils at transplanting followed by a second application at 7 months after planting (MAP) at the rate of 10 t·ha−1, while chemical fertilizer was applied based on the recommended cultivation practice. Data analysis revealed that there was no significant difference between the plants treated with vermicompost and chemical fertilizer in terms of the plant height, number of leaves, length and width of D-leaves, stomatal density and stomatal size. However, the fruits produced with vermicompost amendment were smaller in size but contained higher total soluble solids, titratable acidity, total solids, ascorbic acid and total chlorophyll content compared to the fruits produced from plants supplied with chemical fertilizer. Based on the DPPH, ABTS and FRAP assays, the methanolic fruit extracts from the control plants showed the highest antioxidant potential, followed by those of plants treated with vermicompost and chemical fertilizer. On the other hand, the application of vermicompost reduced soil acidity and produced macro- and micronutrient contents (N, P, K, Mg, Ca, S, Fe, Zn, B and Al) in the soil and plants that were comparable to or higher than those produced by the chemical fertilizer treatment. However, some of the nutrient contents observed in all treatments were lower than the recommended range for pineapple plant growth, suggesting that vermicompost or chemical fertilizer should not be used alone as a source of nutrients for ex vitro MD2 pineapple plants under these soil and field conditions. However, vermicompost can be used as a supplement to increase the fruit chemical quality and maintain the soil quality for agricultural sustainability.
