The experiment consists of twenty-two treatment combinations comprised of two levels of spacing [S1: 30 x 10 cm and S2: 45 x 10 cm] and eleven levels of genotypes [G1: SKAUSJ-WB 185, S2: Tripura Rajma-1, G3: Phule Rajma, G4: Phule Suyash, G5: RKR 1011-1, G6: RKR 1033, G7: GR-1, G8: Varun, G9: HPR-35, G10: IPR-98- 3-1 and G11: Swarna Safal (ICAR Ranchi)]. The results revealed that 45 x 10 cm spacing recorded significantly higher yield attributes and yields of french bean. While among the various genotypes tested, the significantly higher yield attributes and yields were obtained in Swarna Safal genotype of french bean and it also remained at par with Phule Rajma and GR-1 genotypes.

The present study was undertaken to study the seed germination and seedling growth of Silybum marianum (L.) Gaertn. to water-deficit stress under laboratory conditions.Water stress was generated using different concentrations of PEG-6000 (Polyethylene glycol 6000) and the seed germination, seedling growth, proline, lipid and chlorophyll (a, b and total) content were evaluated. The increase in osmotic potential showed significant decrease in germination. Seedling growth parameters decreased with an increase in PEG concentration, except the seedling fresh weight which increased in all the treatments. Proline and MDA content increased with increase in PEG concentrations but chlorophyll content decreased with an increase in water stress.

There are number of stored grain insect pests that infest food grains in farmer stores and public warehouses and massively surge due to un-controlled environmental conditions and poor ware housing technology used. However, for suppression of multiplying insect population highly specific and more appropriate modern methods are to be used. Few important methods such as microwave and ionizing irradiation, pheromone baited traps, IGRs and use of entomopathogens are proved highly effective against stored grain insects. Botanicals have been used since time immemorial for protection of stored products against common pests. They acts as repellents, antifeedants, toxicants and behave as natural grain protectants by behaving as chemosterilants/reproduction inhibitors or insect growth and development inhibitors.

Bioassays, i.e. fumigation with pure essential oils were carried out on adults. Observations were taken after 24 h, 48h, 72 h and 96 h respectively. The LC50 values obtained for 24 h, 48 h, 72 h and 96 h was 0.712(0.597-0.859)%, 0.345(.069-0.474)%, 0.479(0.3320.602)% and 0.397(0.234-0.511)% respectively. The LC50 values obtained for 24 h, 48 h and 72 h for rosemary essential oil are 3.282, 4.261 and 1.509 respectively while the LC50 values obtained for clove oil for 24 h, 48 h and 72 h were 0.334, 0.341 and 0.059 respectively. The present study demonstrated fumigant toxicity against the stored grain pest Callosobruchus chinensis. The essential oil showed ...

In recent years, interest in plant based products has been revived because of the development of resistance, cross-resistance and possible toxicity hazards associated with synthetic insecticides and their rising costs. Presently most of the mosquito repellents available in markets are based on chemical and they are toxic against the skin and nervous system like rashes, swelling, eye irritation, and other health problems. Most of the people still dislike the smoke of the synthetic pyrethroid containing mosquito coils. Hence herbal mosquito repellents were preferred than chemical based mosquito repellents. Essential oils belonging to various plant species and their mixtures have been seen to act as effective repellent against various mosquitoes and pests. The easy availability and less adverse environmental impact have led to the increase...

There were 27 treatment combinations with Zn and Fe were applied either in the soil or as foliar spray with cow dung slurry/FYM/gibbrelic acid/amino acids/2,4- D to onion. Application of Zn significantly increased the bulb weight (73.9 g), bulb yield (45 t/ha) when applied with 2,4-D (3 ppm) as foliar spray. Zinc application significantly influenced the bulb quality and recorded the highest A grade bulbs and the lowest poor quality C grade bulbs when applied with 2,4-D (81.9%) as foliar spray. The maximum medium B grade bulbs were obtained with the application of Fe with cow dung slurry (11.4%). Bangladesh J. Agril. Res. 38(1): 41-48, March 2013 DOI: http://dx.doi.or...

In this process, the progeny of the seed thus produced exhibited a large proportion of monecious plants in the seed production plots. Hence, a modified method of seed production for production of high genetic purity with very high proportion of pistillate plants is advantageous.
