The experiment was laid out in a randomized complete block design with three replications having 17 treatment combinations constituted with different levels of urea super granule (USG) and prilled urea (PU). Result showed that yield of broccoli increased significantly with increasing rate of USG and PU. The treatments containing 160 kg N from USG and 180 kg N from PU exhibited the best performance on yield and yield contributing characters of broccoli having the head yield of 12.9 and 10.6 ton ha -1 , respectively. All the yield contributing characters and the economic profitability were favorably correlated with these high yield performing treatments. The performance of USG in terms of growth, yield and yield attributes, head quality (compactness coefficient) and economic profitability was found significantly higher as compared to that of PU. Therefore, USG @ 160 kg N ha -1 and PU @ 180 kg N ha -1 alongwith other recommended fertilizerscould be suggested for broccoli production in terms of yield and economics.

The experiment was laid out in a randomized block design with four treatments of IBA concentrations: 0 ppm (Control), 2000 ppm, 4000 ppm and 6000 ppm and each treatment was replicated four times. Basal part of tea (BT-2 variety) cuttings were dipped in different IBA concentrations for five seconds. Then these cuttings were dibbled into prepared soil mixture as rooting media. Cuttings were exposed to the rooting media for 90 days and then they all were removed carefully to assess the variation of establishment of cuttings. IBA treated cuttings showed better effect on the rooting rate, root length, root number, shoot length and survival rate compared to the control. It was noted that cuttings treated with 4000 ppm IBA produced the highest rooting rate 79.85%, the highest survival rate 57.60% and the highest root length of 4.85 cm followed by treatment 6000 ppm IBA. In case of all parameters, effects of the treatments 4000 ppm and 6000 ppm of IBA were statistically similar. Positive and strong correlation was observed both in rooting rate versus survival rate and root length versus shoot length in IBA treated cuttings. Thus, IBA at 4000 ppm concentration was recommended for establishment of stem cuttings of tea (BT-2 variety) in the nursery.

The experiment was laid out in a three factors randomized complete block design with three replications. The factors were salinity (two levels: without and 5 dS/m salinity), mulch (two levels: without and with polythene mulch) and irrigation (three levels: 125, 250 and 500 ml water/irrigation). BARI hybrid maize-7 was the test crop. Every pot received the same amount of fertilizer nutrients. Crops were harvested at tassel initiation stage. Mulch increased soil temperature by 2 to 4.5°C (with average of 3.1°C) over without mulch. In without mulch condition, salinity reduced shoot fresh and dry, and root fresh and dry weight by 28.3, 10.3, 39.4 and 30.6%, respectively. In with mulch condition, however, these reductions were 1.0, 7.2, 12.3 and 12.1 %, respectively. Polythene mulch reduced salinity induced reduction of the above parameters by 96.5, 30.1, 68.8 and 60.5 %, respectively.

Thus, the effect of salinity in maize was gradually decreased with the increasing amounts of irrigation water. Soil salinity reduced phosphorus and increased sulphur content in maize plants.

Row to row spacing (RRS) of sugarcane were 80 (S 1 ), 100 (S 2 ) and 120 cm (S 3 ) and sugarcane was intercropped with 1, 2 and 3 rows of potato as 1st intercrop and followed by mungbean with same row ratio as 2 nd intercrop. Sugarcane and companion crops potato and mungbean were cultivated following the cultivation methods of BSRI and Bangladesh Agricultural Research Institute (BARI), respectively. To provide more light to intercrops bended leaves of sugarcane on both sides of rows were cut at middle and compared with non-cutting of leaves in respect of growth and yield of main crop and intercrops as well. The total dry matter production, cane yield and sugar yield were the highest at 120 cm RRS of sugarcane (non-leaf cutting=C 0 ) intercropped with 3 rows of potato followed by 3 rows of mungbean (S 3 C 0 ). The number of tiller and millable canes, and leaf area index (LAI) were the highest at 80 cm RRS of sugarcane (C 0 ) with one row of potato and one row of mungbean (S 1 C 0 ). The effect of light interception on growth and yield of first intercrop (potato) was insignificant whereas it was significant for second intercrop. Yield of mungbean (2 nd intercrop) and light interception ratio (%) was the lowest in S 3 C 1 where sugarcane RRS was 120 cm + 3 R potato followed by 3 R mungbean with leaf cutting (LC).

Although with the application of chemical fungicides, plant diseases can be controlled but the hazardous impacts of such products in human health and environment are well known. Moreover, with their excess applications pest resistance may exist. Natural plant products have been found effective in plant disease managements and could be safely incorporated as suitable alternatives for synthetic fungicides. It is estimated that there are more than 250,000 higher plant species on earth that can be evaluated for their antimicrobial bioactive chemical compounds. During last several decades researchers have evaluated plant extracts and oils against plant pathogens, valuable results have been achieved and some commercially botanical formulations have been prepared and marketed. If we are supposed to move toward production of safer agricultural products, more attention and effort are still needed for production of more commercially botanical fungicides in the near future. The organic agriculture cannot rely on a limited number of commercially pesticides of natural origin, therefore it seems that more researches in formulating more commercially botanical products as fungicides are still needed.
