The present study was aimed to use low cost sesame and sunflower oil cakes as ingredients in feeds for Labeo rohita fingerlings.

Synthetic pesticides, though instantaneously effective, are usually prohibitively expensive, not readily available, may cause hazards to both man and livestock, and inflict injury to the environment. Notable among the alternatives to nematicidesis the use of resistant cultivars, which are inexpensive, and eco-friendly. In the present study, seven okra (Abelmoschus esculentus L.) cultivars were evaluated for their resistance against M. incognita under field condition. Among seven cultivars none of the cultivars were found completely resistant. The cultivars ArkaAbhay and Anoop were found to be moderately resistant to M. incognita with root-knot indices of 3.0 (11 to 30 galls) at 60 days after sowing and at harvest. Arkaanamika, Usha, Rashi-20, Akshay and Solar-10 were found susceptible to M. incognita with root-knot indices of 4.0 (31 to 100 galls) at 60 days after sowing and at harvest.

(i) whole earthworm (ii) earthworm custard, and (iii) pelleted earthworm diet to prepare three iso-nitrogenous (500 g protein kg−1 diet) and iso-caloric (17.0 MJ kg−1 diet) experimental diets. The formulated diets were fed ad libitum twice daily to Labeo rohita advanced fry (0.71 ± 0.04 g) in triplicates for a period of 35 days. In each replicate, 10 fish were stocked. The 300 L fiberglass-reinforced plastic tanks containing 100 L of water with the provision of continuous aeration were used for rearing the fish. At the end of experiment, the weight gain (g), food conversion ratio, specific growth rate, protein efficiency ratio, protein retention efficiency (%), and energy retention efficiency (%) of fish fed pelleted earthworm diet (2.19, 1.58, 4.21, 1.26, 23.0, and 18.6, respectively) was significantly better (p < 0.05) than the corresponding values of whole earthworm (1.53, 2.30, 3.38, 0.84, 14.34, and 11.93, respectively) and earthworm custard (0.94, 3.18, 2.42, 0.62, 10.50, and 8.21, respectively) fed diets.

Finger rot and fruit rot caused by the fungus Lasiodiplodia theobromae (Pat.) Griffth and Maubl are the most important diseases in field as well as post-harvest of banana fruits. In this study, the antifungal activity of total seven fungicides was tested under in-vitro condition against L. theobromae and under in-vivo condition. The results of present study showed that six fungicides at all tested concentrations were a significantly check the fungal growth. At lowest tested concentration (250 ppm) carbendazim and propiconazole were completely inhibited fungal growth. Copper oxychloride at all tested three concentration were stimulated the mycelia growth of L.theobromae. Results of field experiment showed that carbendazim @0.5 gL-1 17 and propiconazole @1mlL-1 18 were completely reduced the percent disease index (PDI) and gave cent percent reduction of the finger rot disease followed by SAAF (97.36%). One hand containing ten fruits were selected from each treated bunch brought to laboratory, kept for ripening under natural Condition up to eating ripening stage the results showed that propiconazole @1mlL-1 21 was highly reduction of PDI (1.50%) and gave highest reduction of fruit rot disease (98.20%) followed by carbendazim (4.005) with increased shelf life of banana fruits. Fruits were dipped in fungicides solution for 2 minutes and kept for ripening results showed that minimum PDI was observed in propicanazole and SAAF (1.00%) treated fruits with 25 maximum reduction of fruit rot disease (98.76%) followed by carbendazim (2.50%) with 96.79 percent reduced fruit rot disease.

It was frequently and abundantly isolated from finger rot in field and post-harvest fruit rot disease in markets as well storage house. Integrated disease management approaches would be an important for the management of post-harvest banana fruit rot disease. Four fungicides such as carbendazim and propiconazole @ 250 ppm, carbendazim 12%+mancozeb 63% @1500 ppm and mancozeb @ 2500 ppm completely inhibited the mycelial growth of L. theobromae and proved statistically superior over the rest of fungicides tested. Copper oxychloride stimulated the growth of L. theobromae. Two extracts such as garlic clove and cinnamon leaf extract at 10% concentration inhibited the mycelial growth of L. theobromae by 47.09 and 33.86% respectively. Five known bioagent tested by dual culture technique showed that Pseudomonas fluorescens and Bacillus subtilis were strong antagonism to L. theobromae by inhibiting mycelial growth up to 75.83% and 70.50% respectively. The results of field experiment showed that single spray of carbendazim @ 0.5 gL-1 , propiconazole @1 mlL-1 , garlic clove and cinnamon leaf extract @100 mlL-1 water, Pseudomonas fluorescens and Bacillus subtilis@1 × 107 CFUml-1 and bunch covered with blue polythene exhibited greater control efficacy to banana finger rot disease in field condition.

Br.) breeding program at Patancheru, India, has developed genetically diverse hybrid parents since 1980s. The present study investigated genetic diversity pattern between two groups of parents in this program, bred till 2004 and developed during 2004-2010. Combined analysis of 379 hybrid parents (current 166 parents and 213 previously developed hybrid parents) carried out using a set of highly polymorphic 28 SSRs detected 12.7 alleles per locus. An average of 8.5 and 8.7 SSR alleles per locus were found in previously developed and current parents, respectively, indicating marginal improvement in the levels of genetic diversity of hybrid parents in this program. Distance matrix differentiated these current and previously developed hybrid parents into 2 separate clusters, indicating infusion of new genetic variability over time as reflected by development of more genotype-specific alleles. Also, the seed and restorer parents were found clearly separated from each other in both the sets with few crossovers, indicating existence of two diverse and broad-based pools in hybrid parents of pearl millet. Restorer parents (R-lines) were found more diverse than seed parents (B-lines), as higher average gene diversity was detected among R-lines (0.70) than B-lines (0.56), though variation between Band R-lines was found reduced in newly developed lines to 9.22% from 16.98% in previously developed lines. Results suggested that newly developed lines were as much divergent when compared with previously developed lines, indicating that current ICRISAT pearl millet breeding program was moving towards development of diverse new hybrid parental lines. The study suggested use of trait-specific donors in Band R-lines separately to maintain sufficient genetic distance between seed and restorer breeding lines. It was pointed out to cross parents having higher genetic distance within the seed (B-lines) and restorer (R-lines) breeding programs to derive diverse and productive hybrid parental lines in future.
