Development strategies of small scale conservation farming practices on two wheeled tractor in Bangladesh

  Conservation farming (CF) is an important profitable and competitive agriculture. It is essential for smallholder farming in South Asia. Small farmers use two wheeled tractor small seeders due to the fact that they are more cost effective. This review paper aims to assess the practices of small scale CF farm machinery for two-wheeled tractor and to develop strategies for small scale CF in Bangladesh. Research...

Effects of different stocking densities on tiger grouper juvenile (Epinephelus fuscoguttatus) growth and a comparative study of the flow-through and recirculating aquaculture systems

Two experiments at different water-flow conditions and stock densities in the critical 6-week nursery phase determined growth, survival and feed conversion of brown-marble grouper juveniles at 35 Day After Hatching (DAH) with initial mean body weight of 0.045±0.02 g and total mean length of 15.08±0.4 mm. In the first experiment, juveniles of 35 DAH were kept in an 80 L fiberglass tank with the flow-through...

Isolation and determination of major anthocyanin pigments in the pericarp of P. communis L. cv. ‘Red Du Comices’ and their association with antioxidant activity

  The anthocyanins in the fruit skin of Pyrus communis cv. ‘Red Du Comice’ were isolated, identified and quantified using high-performance liquid chromatography/diode array detection (HPLC/DAD) and HPLC/electrospray ionization/mass spectrometry (HPLC/ESI/MS). The individual anthocyanins were identified by comparing their mass spectral data and retention times with those of standards and...

Post-harvest fruit decay-inducing pathogen in medicinally important Cucumis species indigenous to South Africa

  Crude extracts of wild watermelon (Cucumis africanus) and wild cucumber (Cucumis myriocarpus) fruits have been used extensively in animal, human and plant health in marginal communities of South Africa. However, collected fresh fruits of Cucumis species have high rate of post-harvest decay, without information on disease-inducing causal agents. A study was carried out to isolate, identify,...

Interactive effects of nitrogen, phosphorus and zinc on growth and yield of Tomato (Solanum lycopersicum)

  An experiment "interactive effects of nitrogen (N), phosphorus (P) and zinc (Zn) on growth and yield of tomato" was carried out at North Mingora Agriculture Research Station, Pakistan. The experiment was laid out by three factors factorial in a randomized complete block design (RCBD) and all treatments were replicated three times. Four levels of nitrogen (0, 100, 150 and 200 kg/ha), four levels of...

The impact of different tillage systems and nutrient levels on the biomass and Brix values of sweet sorghum (Sorghum bicolor L. Moench)

  The biomass and Brix content of sweet sorghum was investigated in 2009 and 2010 to determine the most suitable tillage and fertilization treatments. The experiment was carried out at the Biomass Utilization and Crop Production Demonstration Centre of Szent István University. Both humus content and nitrogen (N) supply of the topsoil was insufficient. In 2009, which was a typical drought year, the yields...

Elongation of the uppermost internode for Shuangdi Pei eS, TGMS rice with eui gene

  Shuangdi Pei eS, a thermo-sensitive genic male sterile (TGMS) rice line with eui gene is derived from TGMS rice line Shuangdi S by irradiation with 350 Gy60Co γ-ray. To elucidate the uppermost internode elongation of TGMS line with eui gene, Shuangdi Pei eS and its original TGMS line Shuangdi S were used to study the effects of temperature on panicle exsertion. At 25°C, the...

Increase in rice yield through the use of quality seeds in Bangladesh

  A farmer participatory research was conducted to determine the yield advantage of cleaned seeds over farmer-saved seeds in seven sites in Bangladesh in five cropping (three Boro and two transplant Aman) seasons. In each site, 30 participating farmers transplanted seedlings from cleaned seeds and their saved seeds of the same variety in adjacent plots in their fields. The results show a significantly higher...
