EFFECTS OF GENETIC AND NON-GENETIC FACTORS IN GROWTH PERFORMANCE OF THE SHEEP BREEDS
Genetic enhancement in livestock can be realized through selection and breeding systems in which the influence of genetic and non-genetic factors on productive traits is the utmost imperative feature for obtaining accurate estimates of breeding values. This study was carried out to analyze the genetic and non-genetic factors influencing the growth performance in sheep breeds. The data on the body weight of Kilakarsal, Vembur, Chevaadu, Ramnad White, and Mecheri sheep breeds at different ages were collected for a period of 10 years. The mean daily gains from birth to the weaning period (90 days) and from weaning to one year were estimated. Statistical analysis was performed using R software. The least-square means of birth weight of Kilakarsal, Vembur, Chevaadu, Ramnad White, and Mecheri were 2.4±0.01, 2.62±0.01, 2.37±0.10, 2.57±0.12 and 2.39±0.16 kg, respectively. The least-square means of one-year body weight of Kilakarsal, Vembur, Chevaadu, Ramnad White, and Mecheri were 19±0.16, 19.9±0.16, 21.6±1.62, 24.9±1.62 and 22.9±2.28 kg, respectively. The phenotypic correlations among birth weight and body weights at successive ages showed positive values and varied from low to high. This directed that selection for body weight at birth and or earlier ages would result in genetic improvement in successive ages. At birth, there is no significant difference among breeds. But as age advances breed differences occur. Ramnad White and Chevaadu are heavier than Kilakarsal and Vembur breeds. The effect sex of sheep on body weight was significant. In the selection and breeding programs, the consequences of environmental factors should be included.
Evaluation of antifungal effect of various organic and inorganic salts against Fusarium oxysporum f. sp. pisi causing wilt of pea
Pea (Pisum sativum) is leguminous plants used as food, fodder and vegetables for humans and animals worldwide. Harvesting peas is an important winter crop around the world, including India, which requires cool and moist conditions. The fungal root pathogen Fusarium oxysporum f. sp. pisi, along with other pathogens causes massive losses in pea. An experiment was performed during May-June 2022 at the department of Plant Pathology, College of Agriculture Jabalpur (M.P.) to evaluate the inhibitory activity of twenty organic and inorganic salts was evaluated in the study against Fusarium oxysporum f. sp. pisi at 1.5 and 2% (w/v) concentration. Sodium carbonate (5.00) reduces maximum radial growth of test pathogen at 1.5% (w/v) concentration and result 93.80% growth inhibition, also complete inhibition at 2% recorded. In both 1.5 and 2% (w/v) concentration, ammonium acetate, potassium sorbate, sodium benzoate, sodium metabisulphate and trisodium phosphate completely reduce the mycelial growth simultaneously all these salts results 100% radial growth inhibition. At 2% (w/v) concentration percent growth inhibition was also recorded good in many salts like ammonium carbonate (97.31%), ammonium molybdate (93.18%). MFC, MIC and ED 50 value of salts were tested and all of the salts tested had MIC values that were in agreement with ED50 values.
PHOSPHORUS MANAGEMENT ON ECONOMICS AND NUTRIENT BALANCE OF CHICKPEA-FODDER SORGHUM CROPPING SEQUENCE
The Field experiments were conducted at the College Farm, N.M. College of Agriculture, Navsari Agricultural University, Navsari during rabi and summer seasons of 2014-15 and 2015-16. The treatments comprised for chickpea were two levels and two sources of phosphorus (25 and 50 kg P2O5/ha from SSP and rock phosphate) along with and without VAM (Vesicular arbuscular mycorrhizae) @ 2.0 kg/ha as soil inoculants and one control i.e., control (No phosphorus and VAM to chickpea) and making ten treatment combinations, laid out in a randomized block design, replicated three times. The succeeding fodder sorghum crop was superimposed on the same layout, keeping chickpea treatments as main plots and two fertility levels as sub-plots (75 % of the recommended dose of 60 kg N + 30 kg P2O5/ha and 100% of the recommended dose of 80 kg N + 40 kg P2O5/ha) with total twenty treatment combinations in a split plot design with three replications. The experiments were conducted on the same site during both the years without changing the randomization of treatments. The higher chickpea equivalent yield, net realization obtained from the treatment combination of 50 kg P2O5/ha from SSP + with VAM (T8) to preceding chickpea and application of 100 per cent RDF to succeeding fodder sorghum under chickpea-fodder sorghum cropping system. The balance sheet of soil available N, P and S after two years of cropping cycles were positive with all treatments except N balance observed under chickpea [grown with no P and VAM and 25 kg P2O5/ha from RP alone]-fodder sorghum cropping system. The positive balance of these nutrients increased with increasing levels of phosphorus management to chickpea. The soil available K balance showed a negative balance in all treatments under chickpea-fodder sorghum cropping system.
Optimization of the pre-treatment combinations for the minimal processing of garlic cloves by using I -Optimal Response Surface Methodology
Garlic cloves were blanched (normal, hot water, and steam) and subsequently pretreated with various chemicals. Chemicals studied in this pretreatment experiment were acetic acid in the range of 0-2%, potassium metabisulphite (KMS) in the range of 0-2000ppm, EDTA in the range of 0-1%, and Calcium chloride in the range of 0-2%. The pretreated cloves were stored under ambient conditions (Temp 25-35°C and RH 60-80%) for 15 days before taking observations. The change in allicin activity, change in textural property, and change in colour intensity of the treated clove in reference to fresh cloves were recorded as response in this optimization study. The optimization was conducted following I- Optimal Response Surface Methodology with total 43 runs divided into 5 blocks. The mean ranges for change in allicin content after 15 days of storage were 7.5-93.5% having R2 =0.98, the change in textural properties were from 13.63-86.07 % having R2 =0.97 and colour intensity 7.25-20.04% having R2 =0.99 for the responses. Numerical optimization of the model parameter was resulted into the best combination of the hot water blanching cloves and subsequently dipping in the solution of 2% Acetic acid, 0.307 ppm potassium metabisulphite (KMS), 0.037% EDTA, and 1.9% Calcium chloride for 39.367 minutes having the desirability of 0.839 and second best optimized pretreatment solution for peeled garlic cloves were dipped in the solution of acetic acid 2%, 0.050ppm KMS, 1.2% of calcium chloride for 1.165% having the desirability of 0.789.
Interactive response of organic mulch and different nutrient sources on productivity and profitability of rice - potato cropping system
Several ill effects in soil and human health as well as environmental hazards were noted due to the use of imbalance nutrient application. Nutrient management is necessary to balance the soil nutrient input with the crop requirement. Therefore, the field experiment was conducted during the kharif and rabi seasons of 2020-21 and 2021-22 at Research Farm of ICAR-CPRI-RS, Gwalior, to examine the interactive effects of organic mulch and different nutrient sources on productivity and profitability of rice - potato cropping system. The experiment was conducted in randomized block design with three replications. The treatment combination consisted of two factors such as mulch (No mulch and paddy straw mulch @5 t/ha) and different sources of nutrients (100% RDF, Compost @25 t/ha + Azotobacter @1.25 l/ha + PSB @1.25 l/ha + Jeevamrut @500 l/ha, FYM @25 t/ha + Jeevamrut @500 l/ha and control). Results revealed that, application of paddy straw as mulch @5 t/ha significantly resulted in the highest grain (2.73 t/ha) and straw (5.52 t/ha) yield of rice, tuber and haulm yield of potato (23.48 t/ha and 10.38 t/ha, respectively) and net return (2,54,975 ₹/ha). Among various nutrient sources, application of 100% RDF significantly recorded the highest grain yield of rice (3.81 t/ha), tuber and haulm yield of potato (26.43 t/ha and 12.55 t/ha, respectively) as well as improved the system productivity as compared to all other treatments but maximum net return (2,76,630 ₹/ha) obtained under FYM @25 t/ha + Jeevamrut @500 l/ha.
