The study was conducted in Kalomo district of Zambia to phenotypically characterize indigenous chickens in the area in order to initiate the base for strategic improvement of the indigenous chickens. In this study, 476 chickens (245 males and 231 females) were used. The phenotypes were recorded through observation by the researcher while quantitative traits were measured using the tailor’s measuring tape as guided by the FAO guide. Out of 476 birds, 85.29% had normal feathers. The most common shank color was gray-blue (29.41%) with the single comb type being the most dominant (91.18%). The red-white earlobe color was predominant (44.12%). Brown eyed chickens were the most common (52.93%). Body weight was taken using a digital scale. There was a significant difference (P˂0.05) in body weight between males and females, males being heavier than the females (2331±587grams and 1586±245grams, respectively). The overall average body weight was 1969±589grams. There was significant (P˂0.05) positive correlation between all linear body measurements with body weight. Two principal components PC1 (54.50%) and PC2 (11.28%) were extracted which both cumulatively accounted for 65.78% of the total variability. The first principal component accounted for 54.50% of variance and had high significant loadings on all body measurements except for shank circumference. We, therefore, theorize that PC1 can be exploited as selection standards for body weight improvement in Zambian indigenous chickens. The many variations found in this study indicated the huge potential that indigenous chickens have for improvements through selection and good breeding strategies

Lavender ( Lavandula angustifolia Mill. family Lamiaceae) is a perennial and highly drought tolerant plant species. It grows well on calcareous slopes, and produces a fragrant essential oil. The aim of study was to evaluate foliar application of gibberellic acid (GA 3 ) and delaying harvesting for different durations on essential oil and components of English lavender after foliar treatment with 0, 200, 400 and 600 mg l -1 gibberellic acid (GA 3 ). Clevenger apparatus-based water-vapor distillation method was used to determine essential oil and its components by GC-MS. The experiment was established in split plots in randomized complete block design with two factors and 3 replications. The main plots were formed at harvest time and the sub-plots were created by GA 3 applications. Statistical analyzes were made using MSTAT-C package program. When the GA 3 doses and harvest times interaction were evaluated together, the average essential oil yield of the harvested lavender flowers ranged 6.20 to 8.20 % showing the prominent influence of the concentration of GA 3 and delay in harvesting (in hours) on concentrartration of alkaloids. More than 50 components were identified, the most important among these was 1.8-cineole, linalool, camphor, borneol, lavandulol, and terpinene-4-ol. The amount of linalool, which improves the quality of the essential oil ranged 34.49-38.75%. The minimum and the maximum essential oil values were noted from the flowers harvested after 30 hours (control treatments), and 54 hours from 400 mg l-1 GA 3 treated plants in the same order. However, essential oil contents showed a slight decrease at higher GA 3 treatments and prolonging duration of harvest after respective GA 3 treatments. GA 3 treatments enhanced the quantity of essential oil substantially, and the optimal dose was determined as 400 mg l -1 GA 3 on samples harvested after 54 hours following application. The results further showed that the quantities of essential oil's primary components varied according to harvest time.
薰衣草(薰衣草)是一种多年生、高度耐旱的植物。它在钙质斜坡上生长得很好，并产生一种芳香的精油。本研究的目的是评价在叶面分别用0、200、400和600 mg / l -1赤霉素处理英国薰衣草精油和成分后，叶面施用赤霉素(ga3)和不同时间延迟采收的效果。采用基于Clevenger仪器的水蒸气蒸馏法对精油及其成分进行气相色谱-质谱分析。试验采用2因素、3个重复的随机完全区组设计。在收获季节形成主样地，利用ga3软件创建子样地。采用MSTAT-C包程序进行统计分析。当GA - 3剂量与采收时间相互作用时，采收薰衣草花的平均精油收率为6.20% ~ 8.20%，表明GA - 3浓度和采收延迟(h)对生物碱浓度的影响显著。鉴定出50多种成分，其中最重要的是1.8-桉树脑、芳樟醇、樟脑、冰片脑、薰衣草脑和萜烯-4-醇。芳樟醇的添加量在34.49% ~ 38.75%之间，对精油质量有改善作用。在相同的顺序下，对照处理30小时后收获的花的精油值最小和最大，而400 mg l-1 GA 3处理的植物在54小时后收获的花的精油值最小和最大。然而，高剂量的甘油三酯处理和不同剂量甘油三酯处理后的采收期均略有降低。GA - 3处理显著提高了精油的含量，在施用54小时后收获的样品中确定最佳剂量为400 mg l -1 GA - 3。结果进一步表明，精油主要成分的含量随采收时间的不同而变化。

The effect of system based phosphorus management on crop productivity, profitability and nutrient uptake of rainfed rice-greengram cropping system was studied under medium land situation at ICAR-NRRI, Cuttack, Odisha. The experiment was carried out in both kharif and rabi season of the years 2019-20 and 2020-21. The experiment was laid out in a split plot design with four nutrient management practices in rice viz. recommended dose of fertilizer (RDF), RDF + 25% additional phosphorus(P) through FYM, RDF + 25% additional phosphorus(P) through fertilizer and 75% of RDF (RDF75) in main plots and five nutrient management practices in greengram viz. Control, RDF, RDF + PSB inoculation (RDF+ PSB), RDF + Foliar spray of 2% DAP (RDF + FS) and RDF + PSB inoculation + Foliar spray of 2% DAP (RDF + PSB + FS) in subplots and replicated thrice. Effect of system based phosphorus management had significant effect on productivity, profitability and nutrient uptake by the system. Application of 25 % additional phosphorous to rice through fertilizer improved the rice equivalent yield (REY) and P uptake of the rice - greengram system by 6.6 and 7.1% compared to the application of recommended dose of phosphorus to rice. The same treatment also resulted in significantly highest net returns and B:C ratio from the cropping system compared to all other treatments including application of 25% additional phosphorus through FYM. However, application of PSB and foliar spray of 2% DAP along with recommended dose of phosphorus to greengram improved the REY and P uptake of the system to the tune of 23.4 and 21.3%, respectively, compared to non fertilized plots where as 6.2 and 9.6%, respectively, over recommended dose of P to greengram with highest net return and B:C ratio. Further, application of 25% additional phosphorus through FYM or fertilizer along with RDF to rice followed by application of PSB and foliar spray of 2% DAP along with RDF to greengram produced the highest grain and straw yield, nutrient uptake, gross return, net return and B:C ratio.

A field experiment was conducted at Regional Research Sub-Station (RRS), under Bidhan Chandra Krishi Viswavidyalaya, Chakdaha, Nadia, West Bengal during rainy seasons of 2017 and 2018 to study the effect of different nutrient management on growth, yield and nutrient uptake of hybrid rice. The experiment was laid out in factorial randomized block design with 20 treatment combinations having 4 varieties (3 hybrid varieties and 1 high yielding variety) and 5 combinations of nutrient management in three replications. The treatment combination of Ajay variety with 50% recommended dose of nitrogen (RDN) + 50% RDN from mustard cake + full recommended dose of phosphorus (RDP) and potassium (RDK) recorded the highest plant height but significantly greater values of leaf area index at 75 days after transplanting (DAT), leaf area duration at 30-90 DAT, dry matter accumulation and crop growth rate at 60-75 DAT were recorded in the treatment combination of Arize 6444 with 75% RDN + 25% nitrogen through mustard cake + 20 kg ZnSO4 /ha. In terms of yield attributes and yield treatment combination of hybrid variety Arize 6444 when combined with either of the fertilizer treatment i.e., 50% RDN + 50% RDN from mustard cake + full (RDP) and (RDK) or 75% RDN + 25% RDN from mustard cake + RDP and RDK + 20 kg ZnSO4 ha-1 recorded significantly (p= 0.05) best results. Hence, this combination could be more effective in augmenting growth, yield and nutrient uptake in the Gangetic plains of West Bengal.

A field experiment was conducted at Regional Agricultural Research Station, Maruteru, Andhra Pradesh during kharif season of 2016 to study the site-specific nutrient management approaches for enhancing productivity and profitability in rice (Oryza sativa L.). Nutriexpert is a decision support tool developed by the International Plant Nutrition Institute (IPNI). Application of fertilizers based on the Nutriexpert was (112-31-58) higher nitrogen, lower phosphorus and potassium than the recommended dose of fertilizers (90-60-60) during kharif season for rice. The treatments included recommended fertilizer (T1), Site Specific Nutrient Management (SSNM) based on Nutrient expert (T2), SSNM based on Leaf Colour Chart (50% N as basal and rest 50% based on LCC (T3), T2 minus Nitrogen (T4), T2 minus Phosphorus (T5), T2 minus Potassium (T6), Absolute control (without N, P and K) (T7) and Farmer's Practice (T8) . The results revealed that the highest grain yield (6317 kg ha-1) and straw yield (7663 kg ha-1) of rice was recorded in T2- SSNM (NE) which is significantly superior over all other fertilizer treatments. Application of major nutrients based on nutriexpert recorded higher uptake of nitrogen (128.50 kg ha-1), phosphorus (27.15 kg ha-1), and potassium(137.32 kg ha-1). Nutrient omission and control treatments recorded significantly lowest grain and straw yields of rice and also nutrient uptake. Hence, nutriexpert not only saves the fertilizers but also helps in increased grain and straw yield of rice.
2016年秋季，在安得拉邦马鲁特鲁地区农业研究站进行了田间试验，研究了提高水稻(Oryza sativa L.)生产力和盈利能力的特定场地营养管理方法。Nutriexpert是由国际植物营养研究所(IPNI)开发的决策支持工具。营养专家建议的氮肥施用量(112-31-58)高于建议的氮肥施用量(90-60-60)，磷、钾用量低于建议的氮肥施用量(90-60-60)。处理包括推荐施肥(T1)、基于营养专家的定点营养管理(T2)、基于叶色图的定点营养管理(SSNM) (50% N作为基础，其余50%基于LCC (T3)、T2负氮(T4)、T2负磷(T5)、T2负钾(T6)、绝对对照(不含N、P、K) (T7)和农民实践(T8))。结果表明，T2- SSNM (NE)处理水稻籽粒产量最高(6317 kg ha-1)，秸秆产量最高(7663 kg ha-1)，显著优于其他所有施肥处理。根据营养专家的主要营养物质的施用记录了较高的氮(128.50 kg ha-1)、磷(27.15 kg ha-1)和钾(137.32 kg ha-1)吸收量。遗漏养分处理和对照处理的水稻籽粒和秸秆产量以及养分吸收量均显著降低。因此，营养专家不仅节省了肥料，而且有助于提高水稻的籽粒和秸秆产量。

This study aims to determine the effect of several types of seaweed extracts on growth and yield of rice. On summer rice, three types of bio-stimulants (Soligro, Opteine, and Biozyme) along with vermi-wash were applied in different formulations i.e. granular and foliar application and at different growth stages (Basal, Tillering, and Panicle initiation Stage) along with recommended dose of fertilizer (RDF). The highest grain yield was found under 100% RDF+ Opteine liquid at 30 DAT (Days after transplanting) and 60 DAT treatment resulting in an increase by 35.03% grain yield over control but the straw yield was highest under the application of 100% RDF+ Soligro Granule at 30 and 60 DAT. Nutrient uptake (N, P and K) by grain and straw and soil microbial population were found maximum under 100% RDF + Soligro Granule at 30 DAT and 60 DAT.

Aromatic rice is a special class of rice known in the Indian subcontinent. A total of fifty-eight aromatic rice genotypes were evaluated on the basis of 12 agro-morphological traits at Agricultural Experimental Farm, University of Calcutta, Baruipur, West Bengal to characterize and estimate genetic diversity. Phenotypic coefficient of variation exhibited higher values but maintained close relation with genotypic coefficient of variation for all the traits. Additive gene action was prominent for traits like plant height, panicle length, number of filled grains per panicle and 1000 grain weight. A correlation study showed that grain yield per plant was positive and significantly correlated with tillers per plant, panicles per plant, number of filled grains per panicle, total number of filled grains per plant and 1000 grain weight. The principal component analysis revealed that total number of filled grains per plant had a strong relation with grain yield. Based on Manhattan clustering, fifty-eight genotypes were grouped into five distinct clusters. 24 genotypes in cluster III,17 in cluster I, 9 in cluster II,7 in Cluster IV and 1 genotype in Cluster V.
