Background: Mung bean is important pulse crop having low productivity. Considering the constraints, it is worthwhile to study the influence of different seed hardening and foliar spraying treatments on the production potential of mung bean. Methods: Mung bean var. GAM-5 was imposed with seed hardening treatments and also for foliar spray using CaCl2 2% and 1%, CCC 500 mg/L, CCC 1000 mg/L, NAA 25 mg/L, NAA 50 mg/L during summer season of 2015-16 and 2016-17. These treatments were evaluated for their dry matter partitioning at field conditions. Result: The leaf dry matter decreased in all the treatments after 60 DAS at the time of pod development upto harvest. There was a very less rate of increase in the stem and root dry matter from pod development stage till the harvest leading to an increase in pod weight. The translocation process must have been more prominent in the treatment CaCl2 2% seed hardening + 1% spraying at 30 DAS (T11) than rest of the treatments and was less in untreated control treatment indicating that photosynthesis and translocation efficiency increases by seed hardening and foliar spraying treatments with agrochemical and growth regulators for increasing the pod yield. Therefore, the treatment T11 was more efficient in dry matter production and its partitioning in leaves, stem, root and pods by allocating maximum dry matter to the pods.

The experiment was conducted to study the effect of salicylic acid (SA) as foliar spray on yield and yield contributing characters of BRRI Hybrid dhan3.The experiment was laid out in a randomized complete block design (RCBD) with three replications and six treatment combinations as, T1: 0 μM SA, T2: 200 μM SA, T3: 400 μM SA, T4: 600 μM SA, T5: 800 μM SA and T6: 1000 μM SA. The results revealed that biomass production, dry matter production and yield and yield contributing characters were significantly increased due to the foliar application of SA. At the maximum tillering (MT) stage, the highest biomass production (15.0 t/ha) and dry matter production was observed in T3 treatment. Treatments T4, T5 and T6 showed significant variation on the effective tillers/hill. The maximum effective tillers/hill were found in the treatment T6. The percentages of spikelet sterility were decreased with increasing the level of SA and the percentage of filled grains/panicle were increased with increasing level of SA. The insect infestation was reduced with increasing level of SA to up to 1000 μM. The maximum grain yield (9.21 t/ha) and straw yield (9.22 t/ha) was found in the treatment T6 which was identical to T5. On the other hand, in all cases the lowest results were found in the control treatment. The result showed that grain yield of rice increased with increasing level of SA to up to 1000 μM (T6 treatment). Our results suggest that foliar spray of SA might be applied to increase the yield of hybrid rice in Bangladesh.Res. Agric., Livest. Fish.4(3): 157-164, December 2017

The effect of serial planting on dry matter production, leaf area, grain yield and yield components cf Lupinus angustifoiius (cvv. Uniwhite, Uniharvest and Unicrop) and L. albus (cv. Ultra) was investigated in field plots at Rutherglen in 1973 and 1974. Delayed planting reduced dry matter production of all cultivars, and leaf area for Ultra. Differences in dry matter partitioning were observed between the late flowering Uniharvest, and the early flowering Unicrop and Ultra. In Uniharvest, delayed plantings resulted in a greater proportion of total dry matter being produced during the flowering phase, whereas the reverse was true for Unicrop and Ultra. The later flowering cultivars showed marked grain yield and yield component reduction with later sowing. Yields were reduced by 160.6 kg/ha and 222.5 kg/ha for each week's delay in sowing Uniharvest and Uniwhite, respectively. This effect was offset in the early flowering cultivars by greater development of lateral branches. In addition, when Unicrop and Ultra were planted in April, pod and flower abortion on the main stem resulted from low temperatures at flowering time. Optimum sowing time was early April for Uniwhite and Uniharvest, and early May for Unicrop and Ultra. Excellent vegetative growth under ideal moisture conditions highlighted the poor harvest indices of lupins and the scope for genetic improvement in the genus.

A pot experiment was conducted with five selected rapeseed/mustard genotypes (BJDH-11, BJDH-12, BJDH-20, BARI Sarisha-14, and BARI Sarisha-16) under two sowing dates (November 20 and December 20) for evaluating their responses to sowing date induced high temperature stress during rabi season of 2017-18. Sowing dates induced temperature variability showed remarkable changes in pheonlogy, leaf area, leaf chlorophyll content, dry matter production and seed yield. Although December 20 sown crop received lower temperatures (minimum 9.8 to 13.2 and maximum 22.6 to 27oC) than November 20 sown crop (minimum 14.8 to 16.4 and maximum 21 to 27.2oC) at flowering but reverse was found at grain development stage. Grain development stage of November 20sown crop received lower temperatures (minimum 8.2 to 13.2 and maximum 24.1 to 27 oC) while December 20 sown crop received higher temperatures at grain development stage (minimum 8.2 to 18 and maximum 22.6 to 32.5oC).As a result December 20 sown crop matured earlier (6 to 9 days) than November 20 sown crop. Leaf area/plant was higher in December 20 sown crops compared to November 20 sown but total dry matter production was more or less same in both the sowing dates. Leaf chlorophyll content did not show any remarkable variation due to variation in sowing dates. However, antioxidant activity like Catalyse (CAT), Peroxidase (POD) Ascorbate peroxidase (APX) and Malondial dehyde (MDA) were found higher in December 20 sown crops than that of November 20sown. Higher activity of APX, POD and CAT with lower activity of MDA indicates comparatively high temperature tolerant genotype. Among the genotypes APX, POD and CAT activity were found higher with lower activity of MDA in BJDH-11 and BJDH-20 and these genotypes also gave higher yield than others. On the basis of growth parameters, antioxidant activity and seed yield of genotype BJDH-11 and BJDH-20 could be select as terminal high temperature tolerance genotypes. Bangladesh Agron.

The objective of this study was to utilize aGlycine maxRIL population to (1) evaluate foliar trigonelline (TRG) content in field-grown soybean, (2) determine the heritability of TRG accumulation, and (3) identify DNA markers linked to quantitative trait loci (QTLs) conditioning variation in TRG accumulation. Frequency distributions of 70 recombinant inbred lines showed statistically no significant departure from normality(P>.05)for TRG accumulation measured at pod development stage (R4). Six different molecular linkage groups (LGs) (B2, C2, D2, G, J, and K) were identified to be linked to QTLs for foliar TRG accumulation. Two unique microsatellite markers (SSR) on two different linkage groups identified QTL significantly associated with foliar TRG accumulation: a region on LG J (Satt285)(P=.0019, R2=15.9%)and a second region on LG C2 (Satt079)(P=.0029, R2=13.4%).

Environment Study

A semi-controlled environment study was conducted from May to September 1996 in Wageningen, The Netherlands, to investigate the interaction between growth and development in bambara groundnut (Vigna subterranea) and the influence of photoperiod on dry matter partitioning. The experimental design was a split-plot with four photoperiods (10·5, 11·8, 13·2 and 14·5 h/d) and two light treatments: unshaded and shaded (42% light reduction). The selection used was ‘DipC94’ from Botswana. The dates of 50% flowering and 50% podding were determined, and samples of plants were harvested at 22, 36, 50, 64, 78, 92, 106 and 120 days after sowing. Total dry matter production was 41% lower in the shaded treatment than in the unshaded treatment, but the rates of progress from sowing to flowering and flowering to podding decreased by only 3 and 12% respectively. This suggests that growth and development in bambara groundnut are largely independent. Photoperiod influenced dry matter partitioning indirectly, through its influence on the onset of podding. There were, however, no strong direct photoperiod effects on dry matter partitioning, either before or after the onset of podding.

The effects of application of Azospirillum brasilense and thiamine on chlorophyll concentration and forage mass of Urochloa decumbens were evaluated in a small plot experiment conducted in Goiânia, Goiás, Brazil. The treatments were applications of: A. brasilense (concentration of 10 mL/L); thiamine at 2 concentrations: 50 and 100 mg/L; combinations of A. brasilense and thiamine at the 2 concentrations; and a Control treatment (untreated grass). At the first harvest there was a trend for applying A. brasilense, either alone or in combination with thiamine, to increase the concentrations of chlorophyll, but differences were not always significant at P<0.05. Dry mass of forage from applying A. brasilense plus thiamine at 100 mg/L was greater than that for Control and thiamine at both concentrations. At the second harvest, chlorophyll concentrations were not affected by treatment (P>0.05), while dry matter production of forage from applying A. brasilense alone and thiamine at 100 mg/L was greater (P<0.05) than that of Control and thiamine at 50 mg/L. Larger-scale and longer-term studies to validate these preliminary findings are needed.

Spotted pod borer is one of the major biotic constraint for pulses production which can cause damage to the economic plant parts such as flower buds, flowers and pods. The larvae feeds on 39 host species of legume crops. The seasonal incidence of spotted pod borer differed from crop to crop and season to season. However, the peak incidence of larvae was observed at flowering and pod development stage in different pulse crops. Female moths lays flat scaly eggs on floral buds, flowers, leaves, leaf axils, terminal shoots and tender pods. Larvae are translucent with dark brown spots on each segment and larval period lasted from 11 to 21 days and the duration of total life cycle varied from 27 to 36 days on different hosts. The efficacy of chemical insecticides belonging to different groups against spotted pod borer was well established on different pulse crops. Neem products such as neem seed kernel extract (NSKE) or neem oil and biocides like <italic>Bacillus thuringiensis</italic> (Bt) showed different levels of efficacy on different crops.

Aim: To study genetic variability for morphological, yield and its contributing traits in forty groundnut genotypes. Study Design: Randomized complete block design with two replications. Place and Duration of Study: College of Horticulture, Hiriyur, University of Agricultural and Horticultural Sciences, Navile, Shivamogga, Karnataka, India during Rabi 2016-17. Methodology: Forty genotypes of groundnut were evaluated under irrigated and imposed end-season drought conditions. Crop was taken care as per recommended package of practices. Stress was imposed by withholding irrigation at pod development stage (@90DAS) for 20 days in drought block. However, control block was provided with regular irrigations. Observations on different morphological, yield and its related traits were recorded on randomly sampled five plants per genotype per replication in both stress-full and stress-free environments. The mean data was subjected to statistical analysis using Genstat 14.1 software. Results: The analysis of variance revealed that highly significant differences observed for all the traits even at p <0.01 level indicating the sufficient variability exist among the entries for the traits under study. High genotypic and phenotypic co-efficient of variation, high heritability coupled with high genetic advance over mean was observed for number pods per plant, immature pods per plant, pod yield per plant and hectare, harvest index, kernel yield per plant, fresh weight of seedlings and kernels per plant under moisture deficit condition. Conclusion: It’s a clear evidence for lesser influence of environment and predominance additive gene action in germplasm for these traits which offers opportunity for selection, unvaryingly direct selection for these traits could be effective for developing high yielding drought tolerant genotypes.

A field experiment was conducted during rabi season of 2017-18 at Agricultural College Farm, Bapatla to study the effect of seed pre - treatment and foliar application of zinc on dry matter production, partitioning and yield of mungbean under water stress. The experiment was laid out in a split plot design with three replications consists of two main treatments viz., no stress i.e. control (M0) and stress from flowering stage (i.e. from 30 DAS) up to harvest (M1) and seven sub-treatments viz., no zinc application (S0), seed treatment with 0.05% and 0.075% ZnSO4 solutions for 5 hrs before sowing (S1 and S2), foliar spray of 300, 400 and 500 ppm ZnSO4 at 30 DAS (S3, S4 and S5) and water spray at 30 DAS (S6). The results showed that leaf, stem, reproductive parts, total dry matter and seed yield was decreased by 23.0, 23.3, 15.3, 18.7 and 33.6 per cent, respectively in the plants that were subjected to stress from flowering stage over control plants. Foliar zinc spray @ 500 ppm at 30 DAS increased the leaf, stem, reproductive parts dry matter, total dry matter and seed yield by 24.6, 24.8, 20.9, 22.5 and 55.2 per cent, respectively, over untreated plants. Normal irrigated plants sprayed with zinc @ 500 ppm (M0S5) recorded the highest mean values of above parameters and the lowest mean values were recorded by the stressed plants with no zinc application (M1S0). Under water stress, mungbean plants sprayed with zinc @ 500 ppm at 30 DAS (M1S5) increased the leaf, stem, reproductive parts, total dry matter and seed yield by 17.6, 16.4, 23.9, 21.3 and 42.0 per cent, respectively, over unsprayed plants (M1S0).
