In agro-ecosystem, biological control agents like parasitoids and predators are the best alternatives to the pesticides, several of which have been replaced by new chemistry. The newer insecticides are eco-friendly, economical, more selective, highly safe and compatible with several biocontrol agents. Keeping this view the present study was undertaken to assess the effect of acetamiprid on the adults of C. blackburni. Results indicated that the acetamiprid 20 SP had significant adverse effect on the mortality of adults and also adult emergence at higher doses (acetamiprid 20 SP at 80 and 40 g a.i./ha) whereas acetamiprid at 10 and 20 g a.i./ha were found to be safe compared to standard check, monocrotophos.
An experiment was conducted to evaluate the efficacy of physical, cultural, biological, antiviral and chemical management practices individually and integrated disease management against cassava mosaic disease during 2018-2020 under field conditions at Tapioca and Castor Research Station, Yethapur. Among the treatments, hot water treatment @ 520C for 20 minutes+ Yellow sticky trap @ 20 nos. /ac + Foliar spraying of Spirotetramat 150 OD @ 0.14g/ lit at 30 and 45 DAP has decreased cassava mosaic disease incidence (47.22 per cent), whitefly population (3.75 nos./leaf) and increased the tuber yield (52.23t/ha) compared to control.
An open top chamber experiment was conducted in Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore to know the effect of elevated Carbon dioxide (CO2) on plant growth, yield, yield attributes and nutrient uptake of rice and maize. Both the crops were grown under three Carbon dioxide levels viz., 376 µ mol mol-1 CO2 (C0), 550 µ mol mol-1 CO2 (C1) and 650 µ mol mol-1 CO2 (C2). Rice was grown in Irugur (S1) and Padugai (S2) soil series. Irugur soil series was clay loam in texture, taxonomically classified as Typic Ustropept. Padugai soil series was clayey in texture, taxonomically classified as Vertic Ustropept. Results revealed that plant growth parameters like plant height, number of tillers, yield attributes such as number of productive tillers, number of grains per panicle, number of filled grains per panicle, thousand grain weight, grain and straw yield were concomitantly increased from active tillering to harvesting stage. These parameters have high in 650 µ mol mol-1 CO2 than 376 µ mol mol-1 CO2. Padugai soil series recorded significantly higher plant growth parameters and yield attributes than Irugur soil series. Maize was grown in Palaviduthi (S1) and Periyanaickenpalayam (S2) soil series. Palaviduthi soil series was sandy 1oam in texture, taxonomically classified as Typic Rhodustalf. Periyanaickenpalayam series was sandy clay loam in texture, taxonomically classified as Vertic Ustropept. Among the soil series, Periyanaickenpalayam soil series (S2) recorded higher plant height, cob length, number of rows per cob, number of grains per cob, grain test weight, grain yield and stover yield compared to Palaviduthi soil series (S1). Comparison of CO2 levels indicated that, CO2 levels failed to attain the level of significance in growth and yield attributes. But, in both crops interaction between soil series and CO2 levels was failed to attain the level of significance.
Pleurotus is a dominant genus comprising several edible species of great commercial significance. Crop duration of the commercially cultivated Pleurotus sp. is 45 to 50 days. Breeding of new strains for improved quality, early maturity and biological efficiency is an emerging concept. P. djamor isolate woody-1 was collected as natural selection and was found to be short cropping duration of 30 days but it is less palatable having rough texture in nature. It produced very thin, loose and non-rhizomorphic mycelia appearing dull white colour. This isolate was crossed with commercially available Pleurotus variety P. florida having long crop duration of 48-50 days but it is palatable and producing thick, compact and rhizomorphic mycelia with bright white colour. This study investigated to produce and evaluate hybrid progenies having short duration with high yielding potential through intraspecific hybridization between P. djamor isolate woody-1 and P. florida. Hybrid strains viz., K7Pf5, K1Pf4 and K4Pf4 produced 1st primordia in 12-14 days after spawning with total cropping duration of 33-40 days. The efficiency of hybrids produced were compared with their parents and also with other commercially available varieties (P. djamor MDU1 and P. eous var APK-1). Hybrid cultivar governing short duration with enhanced yield and high biological efficiency along with other desirable traits were identified for the benefit of mushroom farmers.
Protease supplementation in the diet will allow decreasing the inclusion of soybean meal and permitting to other cheaper protein sources without compromising the nutrient value and ultimate performance. A broiler trial was conducted for a period of 42 days to study the efficacy of protease enzyme addition in the performance of broilers. A total of 500 commercial broiler chicks were divided into 5 treatment groups (T1, T2, T3, T4 and T5). The protease enzyme was added in T4 and T5 at the rate of 0.6 kg per ton. Broiler pre starter, starter and finisher diet was formulated. The temperature during pelleting process was 80-85 oC with the maximum time duration of 45 seconds and the crumble feed was prepared from pellet. Based on the production performance, the cost effectiveness was calculated. The feed conversion ratio was significantly better in protease enzyme supplemented groups when compared to control diet and negative control treatment. The better FCR (1.75) was noted in protease supplementation (0.6 kg/ton) with 100 kcal ME and 1.0 percent protein reduced treatment. Dressing percentage and intestinal length was significantly higher in protease supplementation The protease supplemented group showed lower (Rs 4.57 to 6.59) feed cost than control group.
