An experiment was carried out in Agronomy field of Sher-e-Bangla Agricultural University, Dhaka to find out the performance of wheat (var. BARI Gom 27) as influenced by time of irrigation and different mulch materials during 2015-2016. Four levels of irrigation viz. control, one irrigation at CRI (crown root initiation) stage, one irrigation at flowering stage and two irrigations each at CRI + flowering stage; and four different mulch materials viz. control, rice straw, rice husk and plastic sheets were considered as treatment variables. The experiment was laid out in a split- plot design with three replications, assigning irrigation to main plot and mulch materials to sub plots. Results showed that time of irrigation and different mulch materials had significant effect on plant characters, yield and yield components of wheat. Two irrigations given at CRI + flowering stage resulted with significantly higher plant height, number of spikelets spike-1, number of grains spike-1, 1000- grain weight, grain yield, straw yield and harvest index over one irrigation and control plots. Among mulch materials, black plastic mulch resulted with significantly higher grain yield of wheat. The highest grains (4.15 t ha-1) and straw yields (4.25 t ha-1) were obtained with two irrigations at CRI and flowering stage with black plastic mulch for achieving higher productivity.

An experiment was carried out at research field of Bangladesh Rice Research Institute, Gazipur to evaluate the performance of tidal local aman rice as influenced by urea super granule (USG) at non-tidal condition. Four tidal local aman varieties such as Sadamota, Razashail, Kutiagoni and Kalagura were used as planting materials. Nitrogen was applied as USG (1.8g) at 10 days after transplanting (DAT), 25 DAT, before panicle initiation (BPI) stage (date of PI stage of these 4 varieties were identified from previous experience) and no nitrogen (control). The experiment was laid out in a split-plot design where varieties in main plot and USG in sub-plot with three replications. Varietals response was significant on plant height, effective tillers hill-1, grains panicle-1 and grain yield. All the yield and yield components were influenced significantly by the time of USG application. Higher dry matter was produced by all the varieties when USG was applied at early growth stage (10 to 25 DAT) but crop lodges at milking stage due to more vegetative growth resulting increases sterility, decreases grain fertility and yield. On the other hand, when USG was applied at BPI stage grain fertility and yield were increased. The highest grain yield (3.51 t ha-1) was recorded from Kalagura when USG applied before panicle initiation stage. So, application of USG at BPI stage in local aman rice in non-tidal condition increased yield resulting higher gross and net return in all varieties.Bangladesh Agron. J. 2015, 18(1): 71-80

To study the effects of cover methods and nitrogen (N) levels on the growth and yield components of tomato Cv. Pear F1, field experiments with a 4x3 factorial design were conducted in the 2019 spring and winter seasons using a randomized complete block design with three replications. The cover methods included four treatments: bare soil (BS), black plastic mulch (BPM), transparent polypropylene row cover (RC), and a combination of BPM and RC (BPMRC) with the RC removed approximately 30 days after transplanting. Nitrogen (N) was applied at three levels (150, 180, and 210 kg N ha-1). Using BPM and RC generally led to an increased air temperature, air humidity, soil moisture, and soil temperature compared to the BS treatment. Higher N rates (180 and 210 kg N ha-1) did not result  in different tomato fruit sizes and fruit weights but positively increased fruit yield and quality (Brix values and fruit dry weight) as compared to the 150 kg N ha-1 addition. The cover methods positively affected the yield components and fruit yield of tomato as well as the fruit characteristics compared to the BS treatment. Using cover materials (BPM and RC) combined with a higher N application significantly increased the yield attributes and fruit yield. The highest fruit yield was achieved under the mulching treatment by black plastic (BPM treatment) combined with a 210 kg N ha-1 application, resulting in 50.90 tons ha-1 in the spring and 58.27 tons ha-1 in the winter.

The experiment was conducted to determine the effect of irrigations and sowing dates on growth and yield performance of wheat in the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of November 18, 2012 to March 30, 2013. The experiment was comprised of two factors, viz. factor A: two irrigations namely irrigation (I) and no irrigation i.e. control (I0), and factor B: three sowing dates such as S1: 1st sowing on 18 November, S2: 2nd sowing on 03 December and S3: 3rd sowing on 18 December. The experiment was laid out in a split plot design with three replications. Irrigation was assigned in the main plot, while sowing time was in the sub-plots. Data on grain yield and different yield contributing characters were taken after harvest. Results indicated that the highest grain yield was obtained with I (2.915 t ha-1) and S1 (2.983 t ha-1). The interaction of irrigation (I) and sowing on 18 November (S1) showed the maximum yield (3.387t ha-1), spike length (17.08 cm), 1000 grain weight (43.4 g), spikelets spike-1 (20.03) and grain spike-1 (65.58) of wheat.The Agriculturists 2016; 14(2) 77-85

Exploring ways to improve stand establishment and crop productivity under abiotic stresses like drought is important. Two years experiments were conducted at University of Agriculture, Peshawar-Pakistan to examine the efficacy of six pre-sowing seed hardening agents. Seeds of wheat cultivar Uqab-2000 were hardened in six different chemicals of various concentration viz; PEG-8000 (10%), CaCl2 (4%), KNO3, (3%), Mannital (4%), NaCl (5%), Na2SO4 (2%) along with water soaking and dry seeds as control for 24 hours and drying back to original moisture content at room temperature. The soaking and drying of seeds was repeated twice for 12 hours. The results showed that pre-sowing hardening of seed with PEG-8000, CaCl2 and KNO3 gave higher germination, decreased days to 50% germination, increased shoot length, root length, seedling fresh and dry weight in laboratory experiment as compared with other hardening and control treatment. Under field conditions, maximum plant height (93.53cm), spikelet’s spike-1 (17.16), grains spike-1 (50.82), 1000 grain weight (39.97 g), grain yield (3482 kg ha-1) and maximum harvest index (32.5%) were observed in PEG-8000 hardened seed than control treatment (2872 kg ha-1). Seed hardened in PEG-8000, CaCl2 and KNO3 gave 30% increase in grain yield as compared to Mannital, NaCl and Na2SO4 which gave 15% increase in grain yield over control treatment.

Field experiments were conducted at Pulses and Oilseeds Research Station, Berhampore, Murshidabad, West Bengal during <italic>pre kharif, kharif and rabi</italic> seasons of 2011-12, 2012-13 and 2013-14 to study the effect of water soluble fertilizer spray on growth and yield of greengram, blackgram, lathyrus, lentil and chickpea. Pulses are mostly grown by the farmers without any fertilizer application, as positive effect of supplying legume plants with supplementary nitrogen was found to have beneficial effect on enhancing growth and increasing seed yield. Five sets of experiments were laid out in a split plot design with three replications <italic>viz.</italic> two levels of basal fertilizer application (F<sub>0</sub> -No basal dose of fertilizer, F<sub>1</sub> -Basal dose of fertilizer application @ 20, 40, 40 kg N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O ha<sup>−1</sup>.) as factor A in main plot and seven levels of foliar spray of water soluble fertilizers at pre flowering stage (no spray, 0.5% NPK(19-19-19), 1% NPK(19-19-19), 2% NPK(19-19-19), 3% NPK(19-19-19), 2% DAP, 2% Urea) as factor B in sub plot. Significantly higher seed yield of pulses were recorded with application of 2% urea spray over basal dose of fertilizer application The lowest seed yield was recorded with no basal fertilizer and spray. Without basal dose of fertilizer application, 3% NPK (19-19-19) spray recorded highest seed yield. Under basal dose of fertilizer application, the results showed a gradual increase in yield with the increase in concentration of NPK (19-19-19) fertilizer spray up to 2%, Among the fertilizer spray treatments irrespective of basal dose of fertilizer application, urea spray was significantly better than all other treatments.

A pot experiment was conducted to determine the effect of zinc and nitrogen on growth, nodulation pattern and yield of cowpea. The treatments were four levels of nitrogen ( 0 , 10, 20 and 30 kg/ha) and four levels of zinc (0, 5, 10 and 15 kg/ha). Application of various levels of nitrogen significantly increased dry matter production/plant , plant height number of branches/ plant, effective nodules/ plant, total nodule / plant, effective nodules weight /plant, pods/plant , seeds/pod and grain yield. Similarly zinc significantly increased plant height, branches / plant, number of leaves/plant, dry matter /plant, effective nodules weight /plant and grain yield. There was no significant interaction between nitrogen and zinc on grain yield.

Tomato cv. Alwadi were grown under floating rowcover, black plastic mulch, mulch plus rowcover, or no protection i.e. control, for studying the effect on yield in terms of earliness, total yield and average fruit size. Early yield was significantly increased by the mulch treatment while the rowcover treatment yielded the least (P < 0.05). Total yield was increased by the mulch and mulch plus rowcover treatments, while the rowover and control treatments yielded the least (P < 0.05). Soil temperature at 10 cm depth varied between 1° to 2°C only under the different treatments. Air temperature under the rowcover exceeded 35 to 40°C on many days, hence causing fruit setting problems and resulting in reduced early yield under the rowcover. Our results show that earliness is enhanced by black plastic mulch, while the rowcover alone can have a negative effect on yield. Time of rowcover removal above the mulch warrants further research.

A field experiment was conducted to observe the osmolyte-induced water deficit stress mitigation during the panicle initiation stage in transplanted rice (Oryza sativa L. cv. BRRI dhan72). At the panicle initiation stage, plants were simulated with four levels of water regimes viz., well-irrigated (D0), water deficit for 5 d (D1), 10 d (D2) and 15 d (D3). Plants were treated with or without 10 mM of proline (Pro) and trehalose (Tre) as foliar spray started at mid-vegetative stage and continued till the end of stress period. Results revealed that water deficit stress drastically reduced most of the plant morpho-physiological attributes while other yield contributing characters were also affected due to prolonged water deficit stress. However, exogenous application of osmolytes like Pro and Tre significantly increased all those morphological, physiological and yield contributing parameters. Foliar addition of osmolytes concomitantly decreased the number of non-effective tillers hill-1 and the number of unfilled grain panicle-1 under water stress condition. Although both the osmolytes performed well under multiple duration of drought stress, the application of 10 mM Pro markedly improved all growth and yield contributing parameters under D1 water deficit stress compared to other stress durations. Hence, it may be concluded that the use of osmolytes would be a prospective remedy against moderate water deficit stress in transplanted rice production.

A field experiment was carried out on a farmer’s field at Kannitamilnadu village in Cuddalore district, Tamilnadu during 2018 to find out the suitable organic inputs and pattern of mulching for better growth and yield of roselle (Hibiscus sabdariffavar. sabdariffa). The experiment was laid out in a factorial randomized block design with five levels of organic manures and four levels of mulching with three replication.. Best of the interaction effect was due to the combined application of 25 t FYM + 3 t poultry manure ha-1+ plastic mulch (M3S2) which recorded the highest values for all growth and yield parameters viz., plant height (228.3 cm), number of branches (14.5), leaf area (308.9 cm2), number of calcyes/plant (33.5), calyx yield/plant (233.9 g) and calyx yield/ha (6568.75 kg). The lowest values of these parameters were recorded under control (no organics and no mulching) treatment
