Background: Blackgram (Vigna mungo L.) is an important short duration crop and is grown throughout the country. Seed treatment can improve seedling establishment and better crop stand; it also improves plants ability to tolerate stress at early growth stages and foliar application has the advantage of quick and efficient utilization of nutrients, elimination of nutrient losses through leaching and fixation in soil and also helps in regulating the uptake of nutrients by plants thus improving productivity. Methods: A field experiment was conducted during rabi 2018 at the Instructional Farm, College of Agriculture, Vellayani, Thiruvananthapuram to assess the effect of different levels of seed treatments and nutrient schedule on the growth and yield of blackgram. The growth attributes, yield attributes and yield viz., number of pods per plant, seeds per pod, length of pod, 100 seed weight, grain yield, haulm yield and harvest index were favorably influenced by the treatments. Result: Seed treatment with borax @ 1 g kg-1 seed and sodium molybdate @ 1 g kg-1 seed were observed superior in increasing plant height (135.84 cm), number of trifoliate leaves per plant (7.61), pods per plant (24.16), length of pod (5.23 cm), 100 seed weight (6.74 g), grain yield (1005 kg ha-1) and harvest index (0.38). Significantly higher nodule number (41.83), effective nodule number (33.83) and weight of nodules (58.83 mg) plant-1 at flowering were documented with sodium molybdate @ 1 g kg-1 seed. In case of seeds per pod significantly higher number of pods per plant (7.33) was observed with borax @ 2 g kg-1 seed and maximum haulm yield (1854 kg ha-1) reported with sodium molybdate @ 1 g kg-1 seed. The basal application of ½ N + full P + ½ K followed by ½ N and ½ K as foliar spray of 13:0:45 at 15, 30, 45 and 60 DAS produced significantly more 100 seed weight (6.52 g), grain yield (872 kg ha-1) and haulm yield (1750 kg ha-1). Interaction effect of boron and molybdenum also showed significant influence with respect to yield attributes and yield.

A field experiment was conducted at the experimental field of the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2013 to March 2014. Four soybean genotypes i.e BU Soybean1, BD2329, BD2331, AGS313 and a check variety BARI Soybean 6 were used to evaluate their variations in morphological characters and yield attributes. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The highest LAI (4.4) was found in genotype AGS313 and the smallest was found in BU Soyabean1. The highest pod size of 625 mg pod-1 was found in AGS313 while the lowest of 340 mg pod-1 was observed in BU Soybean1. Although BU Soyabean1 had smaller seed size but it had higher number of pods plant-1 (32.1) compared to other genotypes. The maximum 100-seed weight was recorded in AGS313 (16.34 g) and the minimum was obtained from the genotype BU Soybean1 (11.0 g). AGS313 genotype contributed to the highest grain yield of 4.29 tha-1, while BU Soyabean1 stood second position contributing 2.65 tha-1. Results also indicated that not only seed size but also number of pods plant-1 contributed to grain yield. Again there were highly significant differences among genotypes for all the characters.J.

This experiment was conducted at the Agricultural Botany experimental field of Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka during the period from January to April 2014 to study the effect of sowing times on the yield attributes of an exotic (China) hybrid rice variety in Bangladesh. Five treatments were considered regarding 5 sowing dates or transplanting dates viz. (i) S1 = 1st sowing at 1st January 2014; transplanted at 21st January, (ii) S2 = 2nd sowing at 21st January; transplanted at 11th February, (iii) S3 =3rd sowing at 11th February; transplanted at 3rd March, (iv) S4 = 4th sowing at 3rd March; transplanted at 23rd March and (v) S5 = 5th sowing at 23rd March; transplanted at 13th April. Data were recorded on different growth parameters to examine the effect of sowing times on the yield attributes of the tested variety. The studied parameters were significantly affected by different sowing times or transplanting times. Results revealed that different parameters regarding yield attributes, the seeds of the test variety sown at 1st January 2014 and transplanted at 21st January (S1) furnished the best results in respect of the weight of filled grain hill-1 (38.87 g), weight of filled grain plot-1 (2.18 kg), 1000 seed weight (36.00 g), grain yield ha-1 (3.64 ton) and the highest harvest index (43.46%) compared to the seedling transplanted on other dates or times. These findings can be used in further breeding program.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.

The efficacy of seed treatment and foliar spray with fungicides in controlling black point incidence of wheat seeds was evaluated in the field. Two seed treating fungicides, namely Vitavax-200 and Homai-80WP were used @ 0.25% of dry seed weight and foliar spray with Tilt-250EC (0.05%) was applied in six different schedules. Untreated and unsprayed controls were also maintained. Seed treatment with either Vitavax-200 or Homai-80WP significantly increased plant population and grain yield, but none of them was found effective in reducing black point incidence. On the other hand, foliar sprays with Tilt-250EC under all the spray schedules except spraying at 70 and 90 DAS significantly minimized the disease severity over unsprayed control. Among the different spray schedules, spraying at 30, 40, 50, 60, 70, 80, and 90 DAS appeared to be most effective, which was similar to spraying at 30, 45, 60, 75, and 90 DAS in reducing black point incidence and increasing grain yield. Economic analysis on yield advantage showed that the highest additional gross margin of Tk. 6120/ha with BCR 2.57 was obtained from five sprays applied at 30, 45, 60, 75, and 90 DAS.

Forty five hybrids derived from a diallel mating design of ten parents and one standard check PUSA CHARI-121 were evaluated for general and specific combining ability effects and standard heterosis for grain yield/plant, dry fodder yield/plant, days to 50 per cent flowering, plant height, number of leaves/plant, leaf length, leaf breadth and 100- seed weight of Sorghum bicolor. The mean square due to general and specific combining ability was significan for Days to 50% flowering, Days to maturity, Plant height (cm),No of Leaves/plant, Leaf length (cm), Leaf width (cm), seed yield/plant (g), Fodder yield/plant (q/ha) and 100-seed weight (g) for all the characters. Both additive and non additive genetic effects were present in the material under study. However the ratio of σ2gca/ σ2sca suggested that the preponderance of non additive gene action in expression of all the characters under study. Out of the nine parents PUSA CHARI-121, PANT CHARI-4, MP CHARI, PANT CHARI-6 and PANT CHARI-5 identified as good general combiner for grain yield/plant, dry fodder yield/plant and other agronomical traits. The hybrid HC-136 x PANT CHARI-4 and PANT CHARI-4 x PUSA CHARI-121 for grain yield/plant and hybrid MP CHARI x PANT CHARI-6, PANT CHARI-5 x SPV 1616 and HC-136 x PANT CHARI-4 for dry fodder yield/plant exhibited higher magnitude of positive significant specific combining ability effect with highest standard heterosis and per se performance. These hybrids were also found suitable for two or three yield contributing traits. In general, close association between specific combining ability effects and standard heterosis was observed among the best hybrids identified on the basis of specific combining ability effects for grain and dry fodder yield.

Background: The production of pulses recorded a negative growth rate due to stagnation in expansion of pulse growing area and very slow progress in the improvement of productivity of important pulses. Therefore, there is urgent need to increase the area under pulse crops by promoting them into new areas and seasons. Blackgram [Vigna mungo (L.) Hepper] is third most important pulse crop both in acreage and production in India and hence, identification of high yielding dual season (kharif and summer) stable blackgram genotypes is very crucial for horizontal expansion of crop, which in turn leading to increased production. The present study was thus envisaged to identify stable, high yielding dual season (kharif and summer) genotypes. Methods: Twenty-five blackgram genotypes were evaluated at three different locations during kharif and summer seasons to identify high yielding, stable and suitable for dual season. The data obtained from six environments was subjected to stability analysis as per Eberhart and Russell (1966).Result: Analysis of variance for stability revealed that variance due to genotypes, environment and environment + (genotype × environment) were highly significant for all the characters. The genotypes viz., TRCRU-136, BDU-20, BDU-18, AKU-15 and TRCRU-22 were found early maturing with wider adaptability to unfavourable environments. While, BDU-18 and LBG-465 were found stable in expression with high mean performance across the six environments for 100-seed weight. From the present study, six promising stable genotypes viz., BDU-17, TRCRU-22, BDU-18, TRCRU-339, TRCRU-18 and IC 436778 were identified for cultivation during kharif as well as summer seasons.

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research experiment was conducted in a farmer’s field at Pudhupalayam, Coimbatore to investigate the effect of foliar application of PPFM, plant growth regulating compounds and nutrients on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2019 (kharif and rabi) season. The treatments include 100% recommended dose of NPK along with foliar application of diammonium phosphate (DAP), brassinolide (Br), salicylic acid (SA) and pink pigmented facultative methylotrophs (PPFM) with different concentration (1%, 2%, 1 ppm, 2 ppm, 50 ppm, 100 ppm, respectively) in addition to control. PPFM and PGRs were sprayed at 30 and 45 days after the sowing of blackgram. Result: The experiment results of the two seasons study revealed that the application of 100% RDF + PPFM @ 2% recorded higher growth characters viz., plant height (cm), number of branches plant-1, leaf area index and yield attributes viz., number of pods plant-1, number of seeds pod-1, pod weight (g), pod height (cm), 100 seed weight (g) and yield viz., grain yield (kg/ha), straw yield (kg/ha) and harvest index (%). As well as the same treatment recorded higher net return and B:C ratio. Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield with a magnitude of 1.91 and 1.67, respectively. Therefore, application of 100% RDF+2% PPFM spray can be recommended as the best technology to improve the yield and economics of blackgram.
