<p>The investigation of various nutrition systems in hemp plays an influential role in improving its production. An experiment was conducted in University of Birjand, Iran, during 2013-2014, in which manure (0, 10, 20, and 30 t.ha-1 of cow manure) was considered as the main plot and the combination of nitrogen (0, 50, and 100 kg N ha-1 as urea) with phosphorus (0 and 80 kg P ha-1 as triple superphosphate) fertilizers was considered as factorial in subplots. The type of soil fertility management had no significant effect on the percentage of female plants. Applying 20 t.ha-1 of manure plus 100 kg N ha-1 produced the highest biological yield, seed, and leaf extract. The highest oil content was obtained by applying a maximum of 50 kg N ha-1 without the use of phosphorus. The 30 t ha-1 manure plus 100 kg N ha-1 increased the leaf harvest index and decreased seed harvest index. Nitrogen consumption also increased the seed oil content and yield. Phosphorus increased the biomass and extracts of seed and leaves, also biological, seeds and oil yield. It seems hemp responds well to the combined application of nitrogen fertilizer and animal manure, while its response to P fertilization was limited. </p>

Background: Correlation analysis informs us about the relative importance of the breeding traits and quite useful for plant breeders to formulate their breeding and selection strategies. Path coefficient analysis splits the correlation coefficient into the measures of indirect and direct effect. It identifies the indirect and direct influence of different autonomous genotype on a dependent trait. Present study aimed to determine major seed contributing components affecting seed yield and also to know the relationship among these components. Methods: Present investigation was carried out on 147 advanced breeding lines to know the correlations and path coefficient for 12 yield and yield contributing traits. The material was evaluated in augmented block design with 07 blocks, each block having 21 lines. A set of three check varieties were repeated in each block. Observations were recorded on number of primary branches/plant, number of secondary branches/plant, plant height (cm), silique/plant, fruiting zone length (cm), main shoot length (cm), number of seeds/siliquae, siliquae length (cm), biological yield/plant (g), seed yield/plant (g), harvest index and test weight. Result: The seed yield per plant showed positive and significant correlation with primary branches per plant (0.273), secondary branches per plant (0.280), siliquae per plant (0.627), biological yield per plant (0.744), harvest index (0.188), test weight (0.212) and oil content (0.225). Biological yield per plant (0.5747) had maximum direct effect on seed yield per plant followed by siliquae per plant (0.2438), harvest index (0.127), oil content (0.118) and test weight. These characters have positive and significant association with seed yield per plant. The study thus indicated that biological yield per plant, siliquae per plant, harvest index and test weight are the important characters which should be considered in selection programme in Indian mustard.

Improper doses and splits of nitrogenous fertilizer are two major constraints achieving higher yield of transplanted aman rice in Bangladesh. A field experiment was carried out to study the effect of different levels and split application of nitrogen (N) fertilizer on yield and yield attributes of transplanted aman rice (var. BRRI dhan30). The experiment was laid out in a split-plot design with four split levels of N : T1 [? N a t b asal + ? N a t 2 5 d ays a fter transplanting (DAT) + ? N at 50 DAT ], T2 [½ N at 25 DAT + ½ N at 50 DAT], T3 [? N at 15 DAT + ? N at 30 DAT + ? N at 45 DAT], T4 [¼ at N 15 DAT + ½ N at 30 DAT + ¼ N at 45 DAT] in the main plot and four levels of N in the sub-plot: control (0 kg N/ha), N1 (40 kg N/ha), N2 (80 kg N/ha), and N3 (120 kg N/ha). Data collected were total tillers/hill, effective tillers/hill, number of grains/panicle, grain yield (t/ha), biological yield (t/ha) as well as some other morphological characters. Among the N splits, treatment T3 produced highest total tillers/hill (16.45), effective tillers/hill (12.73), panicle length (24.97 cm), grains/panicle (127.92), grain yield (5.53 t/ha), biological yield (12.87 t/ha), and harvest index (42.79%). Among the N levels, treatment N3 produced highest total tillers/hill (16.50), effective tillers/hill (12.69), grains/panicle (130.36), grain yield (5.40 t/ha), and biological yield (12.66 t/ha). Conversely, the treatment combination of N3 and T3 produced the highest value for most of the traits evaluated, namely total tillers/hill (18.03), effective tillers/hill (14.97), grains/panicle (137.48), grain yield (5.77 t/ha), biological yield (13.08 t/ha), and harvest index (44.10%). Hence, the treatment combination of N3 and T3 is suggested to bring higher economic benefit from transplanted aman rice in the study area.

An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to December, 2013 to investigate the response of some short duration aman rice varieties to date of transplanting. The experiment consisted of three transplanting dates viz. 26 July, 5 August and 15 August and seven short duration T. aman rice varieties viz. BRRI dhan33, BRRI dhan39, BRRI dhan49, BRRI dhan56, BRRI dhan57, BRRI hybrid dhan4 and Binadhan-7. The experiment was laid out in split plot design with three replications. Transplanting dates were allocated into the main plot and varieties into the sub plot. Results indicate that Binadhan-7 produced the highest grain yield (4.90 t ha–1), straw yield (5.58 t ha–1), biological yield (10.44 t ha–1), and harvest index (47.10%). Lowest grain yield (3.27 t ha–1), straw yield (3.96 t ha–1) and biological yield (7.20 t ha–1) were produced by BRRI dhan57. BRRI dhan49 had taken the longest field duration (120 DAT) while BRRI dhan57 had taken the shortest field duration (88 DAT). Plant height (119.12 cm), number of total tillers m-2 (276.40), number of effective tillers m–2 (260.02), number of grains panicle–1 (109.19), grain yield (4.75 t ha–1), straw yield (5.22 t ha–1), biological yield (9.97 t ha–1) and harvest index (47.64%) were highest on 26 July transplanting; decreased on 5 August transplanting and drastically declined on 15 August transplanting. The present study concludes that the highest yield for short duration T. aman rice cultivation could be possible by Binadhan-7 transplanting on 26 July.J. Bangladesh Agril.

The field experiment was conducted at Agronomy Field of Patuakhali Science and Technology University, Patuakhali during the period from December 2019 to May 2020 to evaluate the effect  of phosphorus (P0 = 0 kg P ha-1, P1 = 30 kg P ha-1, P2 = 60 kg P ha-1, P3 = 90 kg P ha-1) and boron (B0 = 0 kg B ha-1, B1 = 4 kg B ha-1, B2 = 6 kg B ha-1) and their combinations on nodulation and yield attributes of soybean. Number of nodules plant-1, number of pods plant-1, number of seeds pod, 1000-seed weight, seed yield, stover yield, biological yield and harvest index increased significantly up to 60 kg P ha-1. On the other hand, number of nodules plant-1, number pods plants-1, number of seeds pod-1, 1000-seed weight, seed yield, stover yield, biological yield and harvest index of soybean were enhanced significantly up to 4 kg B ha-1. The combination of 60 kg P ha-1 and 4 kg B ha-1 depicted the highest number of nodules (177.8), plant height (75.60 cm), number of pods plant-1 (92.72), number of seeds pod-1 (2.92), weight of 1000-seed (155.3 g) seed yield (1.91 t ha-1), stover yield (2.98 t ha-1), biological yield (4.89 t ha-1) and harvest index (39.06%). Thus, the combined application of 60 kg P ha-1 and 4 kg B ha-1 could be the optimum for getting maximum yield of soybean. Bangladesh Agron. J. 2020, 23(2): 127-133

The growth, yield and yield attributing characters of Tilki rice variety was evaluated under different age and number of seedlings hill -1 at Dang, Nepal during rainy season from June to September, 2019. The experiment was laid out into factorial design of two different age of seedlings as viz. 20 days and 30 days as main plot factor and four different number of seedlings hill -1 viz. 1, 2, 3 and 4 as sub-plot factor and replicated thrice. The results revealed that highest plant height (79.69cm) at the time of harvesting , LAI (0.17), panicle length (23.55cm), number of grains per panicle (101.82), effective tiller per hill (9.9), non-effective tiller per hill (1.03), total tiller per hill (10.94), test weight (29.22gm) ,economical yield (2.09ton/ha), biological yield (5.28ton/ha) and harvest index (39.34%) were recorded by 20 days of seedlings. Regarding the number of seedlings effective tiller per hill and harvest index were non-significant. Highest plant height (79.65cm), test weight (28.88gm) and LAI (0.17) were recorded in 1 seedling per hill. Longest panicle length (24.11cm) and more number of grains per panicle (100.48) were also recorded in 1 seedlings per hill. Highest number of non-effective tiller (1.66) and total tillers per hill (11.08) in four seedlings per hill were recorded. Highest economical yield (2.21ton/ha) and biological yield (5.43ton/ha) were recorded in 2 seedlings per hill. The interaction effect of age and number of seedlings per hill showed non-significant relation with all the growth, yield and yield attributing parameters except non-effective tiller per hill and LAI.

Environmental contamination and the excessive use of inorganic fertilizers resulting in stagnant yields of field crops which necessitate the utilization of combined fertilization approach under changing climatic conditions. Current study was aimed to clarify the influence of several fertilizer sources (chemical, organic, organomineral fertilizers) on yield and quality of coriander (Coriandrum sativum L.). The results revealed that the fertilizer sources significantly affected the yield of coriander cultivars. The absence of “Year x Variety x Fertilizer Type” interactions for any of the noted parameters signaled that the detected “Variety x Fertilizer Type” interactions were constant regardless of the year factor. The recorded values of traits according to fertilizer sources different for the plant height from 61.85 to 69.67 cm, number of branches from 5.98 to 7.71 (piece/plant), number of umbels per the main umbel from 5.62 to 7.18 pieces, seed yield from 1.06 to 1.66 t/ha, the biological yield from 4.29 to 5.70 t ha−1, harvest index from 25.29 to 29.41%, essential oil ratio from 0.29 to 0.33%, and essential oil yield from 3.1 to 5.6 L ha−1. Erbaa variety was observed to be superior over the rest of the varieties producing the maximum values of 6.5 L ha−1 of essential oil, 0.36% essential oil content, 30.9% harvest index, 1.81 t/ha seed yield, and 5.9 t ha−1 biological yield with the treatment of chemical fertilizers.

To compare the effects of varying seeding rate on the agronomic performance, phenology and seed quality of hybrid and conventional summer rape cultivars, four hybrid and two conventional summer rape cultivars were seeded at 1.5, 3.0, 4.5, 6.0 and 9.0 kg ha−1 at two locations for 3 yr. The hybrid cultivars were, very importantly, 24% higher yielding and produced 50% more total dry matter than the conventional cultivars. The hybrid cultivars were, on average, 1.3% lower in seed oil content, 1.0% higher in seed protein content and equal in sum of oil and protein in the seed compared with the conventional cultivars. The hybrid cultivars were on average, 1.3 d later to 50% flowering and 1.1 d later to maturity than the average for the conventional cultivars, (i.e., equal or earlier to flowering and maturity than Regent). The hybrid cultivars were also 3.9% lower in harvest index and 1.3 ppm lower in chlorophyll content than the conventional cultivars. In spite of these differences, there were no significant cultivar-by-seeding-rate interactions, indicating that the hybrid and conventional cultivars responded similarly to varying seeding rate. Lodging, days to 50% flowering, days to maturity, harvest index, survival, oil content and protein content displayed significant linear responses to varying seeding rate. Stand at maturity, seed yield and total dry matter production displayed significant linear and quadratic responses to varying seeding rate. Varying seeding rate had no effect on seed formation period, the sum of oil and protein content, or chlorophyll content. A seeding rate of 6 kg ha−1 maximized seed yield for both hybrid and conventional summer rape cultivars.Key words: Brassica napus, canola, seed quality, agronomy, phenology

Background: Assessment of genetic variability and inter-relationship between the characters can be used in the breeding programme to evolve new varieties with wide genetic diversity to maximize the yield potential in crop improvement programmes. Eighty-four field pea genotypes were evaluated in an augmented block design for thirteen quantitative traits to study variance components, heritability, genetic advance and inter-relationship between the yield and yield contributing traits. Methods: The extent of phenotypic and genotypic variation that exist in a character was calculated by the formula suggested by Burton and de Vane (1953). Heritability in broad sense and genetic advance as per cent of mean for each character was computed using the formula suggested by Hanson et al. (1956) and Johnson et al. (1955), respectively. Correlation coefficient was calculated by method suggested by Searle (1961) and path coefficient analysis done as per method of Wright (1921) and elaborated by Dewey and Lu (1959).Result: Significant differences observed among the genotypes tested for the yield characters indicated the presence of variability. High heritability coupled with high genetic advance as percent of mean was observed for the traits viz., plant height, effective pods plant-1, harvest index and seed yield plant-1 were governed by additive gene effects which will aid in effective selection. Correlation coefficient analysis revealed that seed yield plant-1 had highly significant and positive correlation with biological yield plant-1, effective pods plant-1, harvest index, seeds pods-1 and effective nodes plant-1, indicating that these traits are strongly associated with seed yield in field pea. Path coefficient analysis identified biological yield plant-1 followed by harvest index, seed pod-1, effective nodes plant-1, 100-seed weight and day to 50% flowering as highly desirable components with great direct effects on seed yield.

ABSTRACT: This study was conducted to explore the growth stimulating effect of foliage applied brassica water extract on growth and productivity of bread wheat (cv. Punjab 2011) at low and high fertilizer doses. The brassica water extract (5%) and the commercial growth regulator benzyl amino purine (BAP) (5 ppm) were applied alone and in combination at 30 and 45 days after sowing (DAS) under low fertilizer dose (125 kg ha-1 N and 90 kg ha-1 P) and high fertilizer doses (225 kg ha-1 N and 150 kg ha-1 P). Application of the brassica water extract (5%) significantly improved morphological traits such as crop growth rate, leaf elongation, leaf area index, plant height and number of productive tillers under both fertilizer regimes. Similarly, growth regulator benzyl amino purine (5 ppm) application enhanced the growth and yield components of wheat. However, maximum grain yield (6.20 t ha-1) was recorded with combined application of the brassica water extract (5%) and BAP (5 ppm) under the high fertilizer dose followed by individual application of the brassica water extract (5%) and BAP where 5.39 and 5.94 t ha-1 grain yields were recorded. Biological yield also showed an almost similar trend under the influence of the allelopathic water extract of brassica and BAP. Economic and marginal net benefits of 1521.6 and 237.0 USD ha-1 were respectively achieved with the application of the brassica water extract under the lower and higher fertilizer applications, respectively. The foliage applied 5% brassica water extract and BAP (5 ppm) was the most effective and had a stimulating impact on the growth and productivity of wheat.

Radiation Use

Canola tolerant to the triazine group of herbicides is grown widely in Australian broad-acre cropping systems. Triazine-tolerant (TT) cultivars are known to have a yield and oil content penalty compared with non-TT cultivars. This study was designed to elucidate the crop physiological basis for the yield differences between the two types. Two commercial cultivars, near-isogenic for the TT trait, were compared in a detailed growth analysis in the field, and 22 crops were compared for phenology and crop attributes at maturity. In the growth analysis study, the TT trait was found to lower radiation use efficiency, which carried through to less biomass at maturity. There were minimal effects on leaf area development and harvest index, and no effect on canopy radiation extinction. Across the 22 crops, where yield varied from 240 to 3400 kg/ha in the non-TT cultivar, yield was on average 26% less in the TT cultivar due to less biomass produced, as there was no significant effect on harvest index. The difference in oil content (2-5%) was greater in low oil content environments. Flowering was delayed by 2-10 days with a greater delay being in later flowering environments. Quantification of the physiological attributes of TT canola allows the assessment of the productivity of different cultivar types across environments.
