In the present study twenty-eight hybrid combinations resulting from the half-diallel mating of eight quality protein maize (QPM) inbred lines were chosen in order to examine the potential to combine and gene activity for ten yield and component attributes. As part of the All India Coordinated Research Project (AICRP) on maize during the kharif-2020 season, the experiment was done at the research farm of college of Agriculture, Odisha University of Agriculture & Technology (OUAT) Bhubaneswar, using a randomized complete block design replicated thrice. Every observation recorded was subjected to statistical evaluation and it was revealed that the mean squares derived from the general combining ability (gca) and specific combining ability (sca) were highly significant (p ≥0.01). Estimates of sca effects were greater than that of gca effects for all of the variables used in the study, suggesting to the predominance of dominant gene action. The inbred lines Q4-DQL 2221-1-1(833.792), Q2-DQL 2099 (517.658) and Q3- DQL 2159 (350.325) shows high gca effects for yield and its attributing traits due to more additive gene action thus identified as good general combiners for yield. Twelve of the twenty-eight crosses showed significant (p ≥0.01 and 0.05) positive sca effect on grain yield. The best experimental crosses for grain yield based on per se performance and sca effects were Q2 x Q8 (2106.748), Q1 x Q6 (2053.048), Q3 x Q7 (2027.082), and Q3 x Q6 (1719.884).
本研究选择了由八个优质蛋白玉米（QPM）近交系的半二倍体交配产生的 28 个杂交组合，以考察十个产量和成分属性的组合潜力和基因活性。作为全印度玉米协调研究项目（AICRP）的一部分，该实验在奥迪沙农业与技术大学（OUAT）布巴内斯瓦尔分校农学院的研究农场进行，采用随机完全区组设计，重复三次。所记录的每个观测值都经过了统计评估，结果显示，一般结合能力（gca）和特殊结合能力（sca）的均方差非常显著（p ≥0.01）。在研究中使用的所有变量中，sca效应的估计值均大于gca效应的估计值，这表明显性基因的作用占主导地位。近交系 Q4-DQL 2221-1-1（833.792）、Q2-DQL 2099（517.658）和 Q3- DQL 2159（350.325）由于更多的加性基因作用，在产量及其归属性状上表现出较高的 gca 效应，因此被确定为产量的良好一般组合。28 个杂交种中有 12 个对谷物产量表现出显著的正 sca 效应（p ≥0.01 和 0.05）。根据本身表现和 sca 效应，谷物产量最好的试验杂交组合是 Q2 x Q8（2106.748）、Q1 x Q6（2053.048）、Q3 x Q7（2027.082）和 Q3 x Q6（1719.884）。

Yadgir district is identified as most backward ditrict by NITI ayoga on account of their “lowest composite indicators in terms of health and nutrition, education, agriculture, water resources, financial inclusion, skill development and basic infrastructure. Traditional community tanks (TCT’s) are classic examples of common pool resources that have been traditionally managed by local communities for irrigating their crops since age old and they are a living example that illustrates the capability of a man-made tank ecosystem evolved in harmony with nature to withstand natural disasters like drought, floods, and cyclones. These tanks not only protect and conserve the environment, but also contribute to livelihood security to rural farmers. These tanks have contributed significantly in agricultural production through supplementary irrigation and are declined recent decades in Yadgir district which is susceptible to drought compared to other district in the states. Such 13 TCT’s were rejuvenated for enhancing water storage capacity in the district under “Jal Samvardhane -District-wide Water Conservation Project” by Bharatiya Jain Sangh (BJS) In colloboration with Dept. of Agriculture, Yadgir. The study proved that, the average water storage capacity was raised by 24.80 percent in selected rejunuvented TCT’s. The average GWL increased for all selected tanks from 1.62 m to 3.81 m during the post-monsoon seasons of 2019 and 2020, respectively, compared to 1.31 metres before tank disiltation in Rabi 2018. Pigeonpea yield was increased by 4.13 percent (6.56 q/ha) to 20.57 percent (7.62 q/ha) with an average of 11.80 percent across all TCTs. Similarly, cotton prices increased by 4.85 percent (7.13 q/ha) to 21.53 percent (7.45 q/ha) throughout the growing season, with an average of 13.44 percent across all TCTs. Tank irrigation development activities have a substantial impact on groundwater recharge, access to groundwater, and in turn on the extension of irrigated water area. Tank irrigation development efforts have been shown to alter crop patterns, increase crop yields, and diversify crops, resulting in increased employment and farm income of small & marginal farmers of the Yadgir district.

Cattle production has been an important source of livelihood for the rural communities. Current study aimed to documenting the indigenous traditional knowledge and practices related to livestock health care system among the people of Kamlah region of Sandhol tehsil of district Mandi (Himachal Pradesh). Reconnaissance surveys were conducted in this region from 2021 to 2022. A total of 65 informants (35 males & 30 females) were interviewed. Ethnoveterinary data was collected through semi-structured interviews and group discussions with elderly people, women, farmers and local herbal healers. In this study, 28 plant species belonging to 23 families were identified; in which herb (57%) were the maximum used life forms and leaves (43%) were the commonly used plant parts. The highest number of species recorded in families were Asparagaceae and Fabaceae (3 species each). A wide range of diseases or disorders of cattle such as bone fracture, eye infection, fever, heat stroke, insect bite, prolapsed uterus, skin disorders and stomach disorders are treated by the people of study area with the help of indigenous medicinal plants. The data was analysed using three ethnobotanical indices i.e., use value (UV), fidelity level (FL) and informant consensus factor (ICF). According to quantitative analysis, plant species with high UV values for curing live stock were Mentha spicata L. (0.92), Cassia fistula L. (0.77) and Stephania rotunda Lour. (0.77). FL% values ranged from 25 to 100% and ICF values ranged between 0.97 to 1.00. These findings were at primary level and provide basic information to the researchers for carrying out phytochemical and pharmacological investigations, to create more effective veterinary drugs.

India is the largest producer of oilseeds in the world as oilseed sector occupies an important position in the agricultural economy of the country. The study was based on the secondary data from 2002-03 to 2019-20. Major five groundnut producing states were selected based on highest production last triennium average production. The growth rate and instability were computed by using Compound Annual Growth Rate and Cuddy-Della Valle Index. The growth pattern of groundnut witnessed a downward trend with respect to area except Rajasthan state (7.667%). Growth pattern of groundnut indicated a downward trend in respect to production in Andhra Pradesh, Karnataka and Tamil Nadu state. Growth rate in yield (4.442 %)of groundnut was observed highest in Gujarat state. The instability index showed that the fluctuation in production of groundnut was found to be higher in Andhra Pradesh (44.453%) and Gujarat (41.660%). Low rate of instability was observed in area under groundnut crop in Gujarat (9.690%), Karnataka (10.495%) and Tamil Nadu (11.802%).

Six Hydrophilic polymers Xanthan Gum, Iota Carrageenan, Kappa Carrageenan, Agar Agar, Food grade Agar and Gellan Gum were studied for polymerization potential and water holding capacities. Among the six polymers, Xanthan gum and Iota Carageenan recorded the maximum values for water holding capacities of 38.27 ml/g and 34.17 ml/g and were forwarded for the Seed coating experiment. Coating experiments consist of twodosages of polymer powders (10g, and 20g /kg) and two concentrations of sticking agent (water 5ml and 10 ml). Coated seeds exposed to seed germination studies against untreated seeds. Results revealed that Finger millet seeds coated with 20 g Xanthan gum + 10 ml water as sticker recorded the maximum values for seed germination (87%), seedling length (26.23cm), dry matter production (12.47mg 10 seedlings-1)and Vigour Index I (2282) and II (1084).The % increase over the control was 7 for seed germination, 56 for seedling length (cm), 21 for dry matter production (mg) ,69 for seedling vigour index I and 31for seedling vigour index II. From the studies it could be concluded that Finger millet seeds coated with the Xanthangum @20 g can be recommended as pre sowing seed treatment for improving the Seed Germination and seedling vigour.

The morphological attributes play a significant role in determining the level of applied insecticide by the existing spraying system. Therefore, this attempt was made to assess the various morphological attributes of guava tree such as leaf size, leaf area, leaf area index (LAI) and leaf area density (LAD). In this study, two leaf area estimation techniques (grid count method and Image processing technique based on ImageJ software) were compared and also estimate LAI and LAD for ten trees. An average leaf area was registered 29.56 cm2 and R2 value (0.98) for predicting leaf area by image processing technique. The LAI and LAD varied from 0.69 to 2.17 m2/m2 and 0.53 to 1.89 m2/m3, respectively. In addition, minimum and maximum LAD (mean ± SD) for zone wise ranged from 0.07 ± 0.06 m2/m3 to 2.73 ± 1.43 m2/m3, respectively. The study findings provide an opportunity to deal with large volume of leafs for leaf area estimation and would also help in design of various sprayers like determining the dimensions of tunnel sprayer and allow them to test in laboratory conditions with simulated artificial tree.

High temperature affects various physiological processes of the plant. Delayed sowing and changing climate both subject the crop to increasing temperatures during the crop growth period. There is a need to take on a technique to screen the wide number of genotypes for high-temperature tolerance. In the present study, a screening protocol was followed based on the principle of “acquired tolerance” in which 47 sunflower seedlings were exposed to sub-lethal heat stress to induce tolerance before subjecting to subsequent lethal stress and the second set were directly exposed to lethal stress. Significant variation was observed for the traits - survival percentage, total seedling length, and seedling weight. Tolerant inbreds were identified using Z distribution and PCA. Results suggested that TIR is a rapid and powerful technique that can be used to screen large number of germplasms to identify thermotolerant lines.
高温会影响植物的各种生理过程。延迟播种和不断变化的气候都会使作物在生长期间受到不断升高的温度的影响。因此需要采用一种技术来筛选耐高温的大量基因型。在本研究中，根据 "获得性耐受 "原则制定了筛选方案，将 47 株向日葵幼苗置于亚致死热胁迫下，以诱导耐受性，然后再置于致死胁迫下，第二组幼苗则直接置于致死胁迫下。在成活率、幼苗总长度和幼苗重量等性状方面观察到显著差异。利用 Z 分布和 PCA 鉴定了耐受性近交系。结果表明，TIR 是一种快速而强大的技术，可用于筛选大量种质来鉴定耐热品系。
