A biological trial was carried out with 216-day-old Vencobb 400 broiler chicks distributed to six experimental groups with six replicates, each replicate containing six chicks. The experimental groups were fed with control ration (T1), ration with antibiotic oxytetracycline (OTC) at 50 mg/kg (T2), ration with cinnamon oil (CO) at 250 mg per kg and coated sodium butyrate (CSB) either at 0.09 (T3) or 0.18 (T4) per cent levels and ration with CO at 500 mg per kg and CSB either at 0.09 (T5) or 0.18 (T6) per cent levels, lipid encapsulated sodium butyrate was used for the study. The trial was carried out in a deep litter pen for 35 days. The ileal Escherichia coli (5.52-5.71×105 vs. 6.85×106 cfu/g), total bacterial count (8.31-8.53×108 vs. 9.12×109 cfu/g) and Clostridium perfringens (3.90×103-4.23×104 vs. 5.00×105 cfu/g) count were reduced (P<0.01) on the addition of CO and CSB at either low or high levels of antibiotic while the Lactobacillus sp. count in ileal content was not influenced due to supplementation CO and CSB levels attempted or by the antibiotic. The jejunum villi height (1536.78 vs.1287.16 µm) was significantly (P<0.01) increased with the addition of CO and CSB at the levels tried or antibiotic but villi crypt depth and villi height: crypt depth ratio was not influenced by all CO and CSB levels or by the antibiotic. The inclusion of CO and CSB at different levels or antibiotics did not influence the Haemagglutination Inhibition titre against RD.
Heat is one of the most detrimental stress affecting chickpea (Cicer arietinum L.) yields during the reproductive stages. Multi-trait genotype-ideotype distance index (MGIDI) conducted to assess the performance of chickpea genotypes under heat stress conditions indicated strong correlations between MGIDI values, highlighting the impact of environmental conditions on chickpea performance. Advanced multivariate techniques were utilised, including Principal Component Analysis (PCA) and Factor Analysis (FA), to streamline trait selection and genotype identification. FA effectively reduced the dimensionality of the measured traits, simplifying interpretation and decision-making for breeders. The MGIDI emerged as a superior index compared to Heat Susceptibility Indexes (HSI) for selecting genotypes with desirable genetic gain for traits. MGIDI's ability to account for multicollinearity addressed a common issue in breeding experiments with correlated data. Genotype rankings based on the Multivariate Stability Trait Index (MSTI) using MGIDI identified stable genotypes, especially under heat stress conditions. Specific genotypes, including IG5999, IG5875, IG5851, IG 5868, IG5993, and ILC5588, exhibited notable stability and desirable traits. These genotypes hold potential as parents for future crossbreeding programs, aiming to create ideotypes that combine diverse favourable traits.
A research experiment entitled “Impact of pinching on yield and economics aspects of bottle gourd [Lagenaria siceraria (Mol.) Standl.]” was conducted at Punjab Agricultural University - Vegetable Research Farm, Ludhiana and Regional Research Station, Abohar during kharif season, 2022. The experimental were laid out in randomized block design with three replications having nine pinching treatments at different nodes. Pinching treatment was given at main branch and lateral branches of bottle gourd vines in each plot according to the assigned treatments. The results revealed that pinched plants on main branch and lateral branches at 6th node remarkably significantly increased polar diameter of fruit (14.75 cm), equatorial diameter of fruit (13.76 cm), fruit weight (587.91 g), number of fruits per vine (7.23), early fruit yield per plot (14.17 kg), fruit yield (42.50 kg plot-1 and 566.7 q ha-1), harvest duration (68.03 days), overall B: C ratio (3.70:1) and least number of days to fruit harvest (61.97 days). Based on the outcomes presented above, it can be inferred that pinching on main branch and lateral branches at 6th node demonstrates superior results concerning the comprehensive yield aspects in bottle gourd.
To stabilize onion prices throughout the year, cultivation of onion in rabi and kharif season is well accepted. It not only fulfills consumer demand but also provides high remuneration to onion farmers. Production of onion in kharif and late kharif season is a new strategy adopted to supply the fresh onion during November onwards. Recommendation of varieties and their successful cultivation was not done under sub-tropical conditions of Jammu though. Grading of bulbsets was done on the basis of sizes as Grade-1 (3.05cm), Grade-2 (2.55cm), Grade-3 (2.20cm) and Grade-4 (1.55). An investigation was carried out at Division of Vegetable Science, SKUAST-J, Chatha during 2018-2019 to evaluate kharif varieties developed through bulbsets of different sizes by sowing them on different dates. Bolting which started in the plants from the second week of January showed an increasing but non-significant trend among different grades of bulbsets. However, significant differences were found among the varieties with maximum percentage (26.48%) recorded in Selection-1 as compared to minimum (8.28%) in Bhima Red. Size of the bulbsets showed a significant trend as compared to varietal response. Grade-I (D1) showed statistically minimum days (15.50) for 50% sprouting as compared to other size of bulbsets with a maximum days (18.83) in Grade-IV of bulbsets (D4). Neck thickness was significantly influenced by varieties and dates of sowing but their interaction indicated non-significant results. N-53 recorded minimum neck thickness (0.95cm) whereas maximum thickness (1.40cm) was recorded in Selection-1. Large sized bulbsets recorded maximum neck thickness (1.28cm) as compared to small sized bulbsets (1.14cm). Selection-1 took maximum days (151.41) for marketable maturity while Bhima Red took minimum (125.58) days. Among the grades, bulbsets of Grade-IV (D 4) took maximum days (147.25) to maturity as compared to Grade-I (D1) which took minimum 134.50 days. However, non-significant results were recorded in the interaction. The maximum average bulb weight (117.13g) and total yield (449.03q/ha) was recorded in Grade-I (D1) of Bhima Red, sown on 1st February. Significantly maximum marketable bulb yield of 409.14q/ha was obtained in Grade-I of Bhima Red, giving highest cost benefit ratio of 1:3.55.Lowest marketable bulb yield of 174.55q/ha with cost benefit ratio 1:0.95 was observed in Grade-IV of Selection-1.
This study investigated the variation in nutrient content in grape petioles and berries throughout the growing season. The results showed that the mean nitrogen (N) content in petioles ranged from 0.67% to 1.37% and exhibited a decline over the sampling period. Anab-e-Shahi cultivar had higher N levels compared to Perlette. Petiole N showed a positive correlation with phosphorus (P) and potassium (K). Similar periodic fluctuations in petiole N content were observed in other grape cultivars. The mean P content varied from 0.12% to 0.34% and showed a non-significant decrease during early growth stages and a subsequent increase. Petiole P exhibited positive correlations with K and N. The K content increased initially and then decreased throughout the season, with Perlette having higher levels than Anab-e-Shahi. Petiole K showed positive correlations with N and P. The calcium (Ca) content increased gradually, while magnesium (Mg) showed an overall increase from D1 to D9. Boron (B) increased initially and then decreased towards the end of the season. While comparing nutrient status in both leaves and fruits from D6 to D8 macronutrients show maximum flow from source to sink. In case of Nitrogen D6 showed maximum decrease in N in leaves and increase in fruits which means maximum source to sink is in D6 and majority of macro nutrients show similar behavior, while as in case of micronutrients initial stages D5 onwards source to sink gets decreased hence micronutrient sprays should be recommended at initial stages hence nutrient sprays are recommended during these stages for maximum uptake of nutrients from leaves to berries for maximum nutrient fortification in berries. These findings emphasize the importance of considering specific reference levels for each phenological stage and highlight the dynamic nature of nutrient content in grapevine growth and development.
