Aims:   To study the effect of lignite humin (LH) and poultry manure humin (PMH) application on economics of hybrid maize production in an acid soil of eastern dry zone of Karnataka. Study Design: Randomized complete block design (RCBD) comprising ten treatments and three replications. Place and Duration of Study: Krishi Vigyana Kendra, Hadonahalli, Bengaluru rural district (Karnataka) during kharif 2018. Methodology: A field experiment was laid out in a randomized complete block design with ten treatments, replicated thrice during kharif 2018 at Krishi Vigyana Kendra, Hadonahalli, Bengaluru rural district, Karnataka. The Lignite Humin (LH) and Poultry Manure Humin (PH) were applied at different doses (0, 2.5, 7.5 & 10 t ha-1) in combination with FYM (Farm Yard Manure) applied in such a way that the total quantity of humin and FYM is equivalent to 10 t ha-1. Results: The results revealed that significant variation was observed on yield and benefit: Cost ratio due to application of Farm Yard Manure (FYM), LH and PMH. Significantly higher maize kernel (8070 kg ha-1) and stover yield (9948 kg ha-1) were recorded in treatment T2 (100% RDF + FYM @ 10 t ha-1) and which was found on par with treatment T7 (100% RDF + PMH @ 2.5 t ha-1 + FYM @ 7.5 t ha-1) and T3 (100% RDF + LH @ 2.5 t ha-1 + FYM @ 7.5 t ha-1) and T8 (100% RDF + PMH @ 5 t ha-1 + FYM @ 5 t ha-1). Wherein, higher B:C ratio of 2.24 was recorded in treatment T10 receiving 100% RDF + PMH @ 10 t ha-1and it was followed by treatment receiving T2(2.21) and T9 : 100% RDF + PMH @ 7.5 t ha-1 + FYM @ 2.5 t ha-1 (2.20). Whereas the least B:C ratio (1.72) was observed in the absolute control treatment where no manures and fertilizers were given. Conclusion: These results suggest that higher B:C ratio in these treatments might be due to lower cost of cultivation and it increases with increased in dose of lignite and poultry manure based humin.

A study was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Boro season of 2014 to evaluate the effect of integrated use of manures and fertilizers for maximizing the growth and yield of BRRI dhan28. The experiment was laid out in a randomized complete block design with six treatments and four replications. The treatments include T0 [Control], T1 [Soil Test Basis-Chemical Fertilizer], T2 [(Cowdung) + STB-CF] on IPNS basis, T3 [(Poultry Manure) + STB-CF] on IPNS basis, T4 [(Compost) + STB-CF] on IPNS basis, and T5 [Farmer’s practice]. The maximum grain yield of 4340 kg ha-1 (95.59% increase over control) and straw yield of 4024 kg ha-1 (56.42% increase over control) were recorded in T3 [ (PM) + STB-CF]. The lowest grain and straw yields were found for T0 (Control) treatment. The N, P, K and S contents and uptake by BRRI dhan28 were profoundly influenced due to combined application of manures and fertilizers. The performance of the treatment T3 was better than T1, T2 and T4 in producing the yield of grain and straw of BRRI dhan28 although they received the same amount of nutrients. The results indicate that application of fertilizers in combination with poultry manure could be considered more effective in rice production. So, the treatment T3 can be used for the successful cultivation of BRRI dhan28.Res. Agric., Livest. Fish.3(1): 99-104, April 2016

A field experiment was conducted in Tamil Nadu Agricultural University farm, Coimbatore to compare the organic nutrient management packages with integrated nutrient management (INM) in cotton. The experiment was consisted of eighteen treatments, laid out in Randomized Complete Block Design and replicated thrice. The results revealed that INM practices increased the plant height over other treatments. Significant increase in yield components like sympodial branches plant-1, number of bolls plant-1 and boll weight were observed under INM treatment and was at par with recommended dose of fertilizers (RDF), Farm yard manure and poultry manure compared to all other treatment combinations. The INM practice resulted in significantly higher seed cotton yield and was comparable with RDF. The quality characters did not exhibit any significant variation among the nutrient management practices. Higher gross and net returns and B:C ratio were also recorded in INM practices.

AbstractSowing dates and varieties affect the productivity of maize. A field experiment was conducted to find out the response of maize hybrids to sowing dates on growth and productivity of maize in spring season at Lamahi, Dang in 2019. The experiment was laid out in two factor factorial Randomized Complete Block Design with four replications. The treatment consisted of combination of three different sowing dates (February 1, February12 and February 23) and two maize varieties (Arun-2 i.e. OPV and hybrid Bioseed-9220).The result revealed that earlier planting on February 1 produced the highest yield (8265 Kg ha-1) which was significantly superior than latter planting of February 12(6099 kg ha-1)and February 23 (5934 kg ha-1).The higher yield in earlier planting was due to significantly higher no of kernel per ear, non-significant but higher number of cob per unit area, thousand grain weight. Similarly, Bioseed 9220 produced higher yield (7798 kg ha-1) compared to Arun-2 (5,734 kg ha-1). The higher yield of hybrid Bioseed 9220 was because of higher number of cob per unit area harvested and more number of kernel per cob. Therefore, earlier planting with hybrid maize is recommended in spring season of Dang and locations with similar climatic conditions for higher productivity of maize.

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.

A pot experiment was conducted at the experimental net house of the Department of Soil Science, Sylhet Agricultural University, Sylhet, Bangladesh to observe the effect of fertilizers on yield and nutrient uptake of local aromatic rice varieties during the Aman season of 2015. The experiment was laid out in a Randomized Complete Block Design with three replications. Five local aromatic rice varieties (Kalizira: V1, Muktasail: V2, Nagrasail: V3, Maloti: V4 and Chinigura: V5) and four packages of fertilizers (F1:  Recommended package i.e. 45-10-20-10-0.5 kg ha-1 of N-P-K-S-Zn, F2: 2/3rd of recommended package, F3: 1/3rd of recommended package, and F4: Control) were used. Urea, TSP, MoP, gypsum and ZnSO4 were used as N, P, K, S and Zn source, respectively. According to the treatment, all fertilizers were applied as basal during final pot preparation while urea was applied in two equal splits (one half as basal and another half at 40 DAT). Nutrient content and uptake of the aromatic rice varieties were significantly affected by the application of different fertilizer packages (with few exceptions). Mostly Kalizira (1.10-0.44-2.31-0.67-13.75 g pot-1 of N-P-K-S-Zn) and/or Nagrasail (1.15-0.46-2.70-0.62-11.74 g pot-1 of N-P-K-S-Zn) varieties showed the highest nutrient uptake in grain and straw with recommended package of fertilizers. While in maximum cases Chinigura (0.41-0.16-0.76-0.197-3.17 g pot-1 of N-P-K-S-Zn) was observed to have the lowest with control treatment. In case of post harvest soil nutrient analyses, Kalizira and/or Chinigura variety associated with recommended package of fertilizers showed the highest nutrient status.

The experiment was conducted at Multi Location Testing (MLT) site, Moulvibazar, Bangladesh during rabi season of 2016-17 and 2017-18 to study the profitability of intercropping of hybrid maize with vegetables and spices. Five intercrop combinations of hybrid maize along with sole maize were arranged in randomized complete block design (RCBD) replicated six times. There were six treatments viz., T1: Maize + potato, T2: Maize + red amaranth, T3: Maize + spinach, T4: Maize+ data shak, T5: Maize + coriander and T6: Maize as sole. The grain yield of maize in intercropped combination varied significantly. The highest grain yield (9.71 t ha-1) was in sole maize. The highest maize equivalent yield 15.60 t ha-1 was recorded from the treatment T1 (100% maize + potato) whereas the lowest yield (8.61 t ha-1) was obtained from the treatment T6 (sole maize). The highest gross return (Tk. 312000 ha-1) and benefit cost ratio (3.29) was obtained from the treatment T1 (100% maize + potato). On the contrary, the lowest gross margin (Tk. 101600 ha-1) was obtained from treatment T2 (maize + red amaranth). It revealed that the combination of maize with potato was more compatible and profitable intercropping system in Sylhet region of Bangladesh Bangladesh Agron. J. 2018, 21(2): 73-78

In recent years, National Maize Research Program (NMRP) aimed a paradigm shift from open-pollinated varieties (OPVs) towards hybrid maize to achieve self-sufficiency in maize for food, feed, and hybrid seed within the country. In this mission, it is necessary to identify and deploy high-yielding stress-resilient maize hybrids that can cope with climate change effects, including heat stress. Under the project “Heat Tolerant Maize for Asia (HTMA)”, NMRP introduced the hybrids that performed better in previous years in different environments from International Maize and Wheat Improvement Center (CIMMYT) Hyderabad for multilocation on-farm testing. Fifteen genotypes were evaluated at two locations, two sites in Madi, Chitwan, and one in Ghorahi, Dang, along with Rampur Hybrid-8 as a heat-tolerant check, and RML-86/RML-96 and RML-95/RML-96 as normal checks. Randomized complete block design (RCBD) was used with three replicates during the spring of 2016/17. Likewise, another 20 and 18 promising hybrids were demonstrated during the winter of 2016/17 and 2017/18, respectively, in different hybrid growing pockets considering a site – a replication. Grain yield and yield attributing traits at all locations were recorded. From the across-site data analysis, selected heat-tolerant hybrids from the experiment were CAH1432, ZH15405, ZH141592, and CAH1715 which were statistically at par with promising normal hybrid RML-86/RML-96 and superior to already released heat-tolerant Rampur Hybrid-8. In 2016/17, ZH138098, ZH1620, and VH121062 were farmers’ preferred heat-tolerant hybrids. In 2017/18, Rampur Hybrid-10, ZH141592, CAH1715, and ZH15440 were preferred by farmers. The selected bestbet are taken forward for official release/registration followed by commercialization through a public-private partnership with Nepali seed companies/cooperatives. SAARC J.

The effect of different rates of boron application on wheat cv. Bijoy was studied through a field experiment at    Bangladesh Agricultural University (BAU) farm, Mymensingh during 2009-10 rabi season. The BAU farm belongs to    Old Brahmaputra Floodplain agroecological zone (AEZ 9). Texturally the soil was silt loam, with 7.2 pH, 0.81%    organic matter and 0.15 mg kg-1 available boron content. The experiment was laid out in a randomized complete    block design with five boron rates and four replications. Boron rates were 0, 0.75, 1.5, 2.25 and 3.0 kg ha-1, with boric    acid as a source. Every plot received blanket doses of 115 kg N, 25 kg P, 75 kg K and 15 kg S ha-1 from urea, TSP,    MoP and gypsum, respectively. Treatment receiving B @ 2.25 kg ha-1 produced the highest grain yield (4.22 t ha-1) which was statistically identical with that obtained with 1.75 kg B ha-1. However, the crop response curve showed    1.90 kg ha-1 to be the optimum boron rate for the maximization of wheat yield. The lowest grain yield (2.84 t/ha) was    recorded with control treatment. There was a positive relationship between grain yield and number of grains spike-1.   Boron had significant influence on N, P, K, S and B uptake by the crop which, in deed, was more influenced by crop    yield and less by nutrient concentration, except N and B uptake where concentration had more influence than yield.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.10987   J.

A study was conducted to examine the nutrient content and their uptake of rice as influenced by the application of humic acid (HA) and poultry manure (PM). This experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Three levels each of humic acid (0, 3 and 6 L ha-1) and poultry manure (0, 3 and 6 t ha-1) were applied. BRRI dhan39 was used as test crop. Basal doses of N, P, K and S fertilizers were applied. Both humic acid and poultry manure either singly or in combination significantly affected the contents and uptake of N, P, K, S, Ca and Mg of BRRI dhan39. The maximum content of N, P, K, S and Ca except Mg and their uptake were recorded from the treatment combination of 6 L ha-1 humic acid along with 3 t ha-1 poultry manure.

SummaryThe aim of this paper is to present the comparison of three models applied to the analysis of a one-year study of protein yield for two types of hybrid maize cultivars under different forms of nitrogen fertilizer and doses of magnesium. The field trial was conducted in 2010 at the Agricultural Experimental Station in Swadzim (Poland). The results obtained were analyzed in terms of three randomization-derived models of observations. Consideration was given to three mixed systems, which are combinations of split-plot design, split-block design and randomized complete block design. The relative efficiency of the designs with respect to estimation of some comparisons among treatment combination effects was examined. Particular attention was paid to the interaction between cultivars and nitrogen fertilization.
