The present experiment entitled “Influence of nutrient concentration on Growth, Yield and Quality of Spinach (Spinacia oleracea L.) in Hydroponic system” was carried out in Shade net, Research Field, Department of Horticulture, SHUATS, Prayagraj during March- April,2020.. The experiment was laid out in complete randomized design (CRD), with eight treatments, replicated thrice with nutrient field technique hydroponics system and variety Mulayam of Spinach, the treatments were T1 (NPK 6.25 ml/plant), T2 (NPK 8.33 ml/plant), T3 (NPK 10.41 ml/plant), T4 (NPK 12.5 ml/plant), T5 (NPK 14.58 ml/plant), T6 (NPK 16.66 ml/plant), T7 (NPK 18.75 ml/plant) and T0 (NPK 0 ml/plant). From the present experimental findings, it is found that structure with treatment T4 was found best in terms of Growth and yield parameters of spinach in NFT hydroponic system followed by structure with T3 and T1 due to appropriate supply of plant nutrients and the water treated plants had the lowest values. Maximum gross return (1871.30Rs) and net return (746.30 Rs) and maximum benefit cost ratio (1.66) was also observed in treatment T4. As seen from the experiment, it was observed that the treatment T4 was ideal nutrient for Spinach good growth and yield. Therefore, an ideal nutrient concentration helps the plants in good growth and yield.

This research was formulated to study the response of heat tolerant genotypes to prolonged period of water stress prevalent under rainfed situation. The trial was conducted at Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka, India, during rainy season (kharif) 2019. The present study comprised of three stress tolerant genotypes (RCRMH 2, RCRMH 3 and RCRMH 4) with four moisture stress stages (imposed between 20-40, 40-60, 60-80 and 80-100 DAS) which were sown during June, July and August, and the design employed was Randomized complete block design. The results revealed that superior performance of RCRMH 3 (5321 kg ha-1) over other genotypes whether stressed or not, but all the genotypes were on par with each other in terms of physiological parameters viz., proline accumulation, relative water content, canopy temperature, NDVI, relative chlorophyll content and ASI, and these parameters exhibited good correlation with yield and hence found ideal for stress studies. The present study indicated that these cultivars sustain maize production under moisture stress condition and therefore, are suitable to semiarid region characterized by inclement weather.
本研究旨在研究旱作条件下耐热基因型对长时间水分胁迫的响应。该试验于2019年雨季(kharif)在印度卡纳塔克邦赖丘尔农业科学大学Dhadesugur农业研究站进行。本研究采用随机完全区组设计，选取3个耐胁迫基因型(RCRMH 2、RCRMH 3和RCRMH 4)，分别于6、7、8月播种，水分胁迫阶段分别为20-40、40-60、60-80和80-100 DAS。结果表明，无论胁迫与否，RCRMH 3 (5321 kg ha-1)均优于其他基因型，但各基因型在脯氨酸积累、相对含水量、冠层温度、NDVI、相对叶绿素含量和ASI等生理参数方面基本相同，且这些参数与产量具有良好的相关性，是胁迫研究的理想选择。研究表明，这些品种在水分胁迫条件下仍能维持玉米产量，因此适合于气候恶劣的半干旱地区。

The present investigation was conducted with nine genotypes in randomized block design during Rabi, 2019-20 at the instructional-cum-research farm, Assam Agricultural University, Jorhat. All the characters exhibited significant genotypic mean squares in analysis of variance except anthesis silking interval, kernel rows per ear and 100 kernel weights. High heritability coupled with high genetic advance was observed for the traits plant height, ear height, ears per plant, ear length, kernels per row, chlorophyll content, leaf area index 60 days after sowing (LAI 60 DAS), LAI 90 DAS, harvest index, grain yield per plant and grain yield per hectare. Significant genetic association of grain yield per plant and grain yield per hectare with days to 50% pollen shed, days to 50% silk, days to 100% dry husk, ear height, kernels per row, LAI 60DAS and LAI 90 DAS. Genotypic path analysis revealed that the characters, days to 50% silk, days to 100% dry husk, plant height, ears per plant, ear diameter and harvest index had the highest positive direct effects on grain yield per hectare while days to 50% pollen shed and ear height had the highest negative direct effect on grain yield per hectare. The hybrids namely, PAC 751, CP 333 and PAC 751 ELITE, were found to be the three best hybrids to possess a high estimate of desirable traits such as days to 50% pollen shed, days to 50% silk, days to 100% dry husk, plant height, ear height, ear diameter, leaf area index at 60 days after sowing, lea area index at 90 days after sowing, grain yield per plant and grain yield per hectare.

A field experiment was conducted at Zonal Agricultural Research Station, VC Farm, Mandya during kharif 2017, summer 2018, kharif 2018 and summer 2019 to study the effect of rock phosphate enriched compost on soil nutrient status after harvest of finger millet-cowpea cropping sequence. Prior to initiation of the field experiment, three different composts viz., urban solid waste compost (USWC), vermicompost and farm yard manure (FYM) were enriched with rock phosphate at 5 per cent. Field experiment consisting of eleven treatment combinations comprising recommended N and K, and P through varied levels of enriched composts. The experiment was laid out in RCBD design with three replications and the test crops were finger millet and cowpea. The initial P2O5 of the experimental site was very high (133.58 kg ha-1). The results revealed that application of recommended N and K + 75 per cent P supplied through enriched USWC (T5) had significantly higher organic carbon (0.56 and 0.58%) in pooled data of both finger millet and cowpea, respectively. Available N (241.94 and 224.86 kg ha-1), P2O5 (138.69 and 120.99 kg ha-1) and K2O (153.92 and 135.31 kg ha-1) were recorded significantly higher in T5 of finger millet and cowpea, respectively. Similarly, in pooled mean, exchangeable Ca [4.15 and 4.04 C mol (P+) kg-1] and Mg [2.16 and 2.05 C mol (P+) kg-1] were recorded significantly higher in treatment which received recommended N and K + 75 per cent P supplied through enriched vermicompost (T8) in both finger millet and cowpea, respectively. The decrease of available P2O5 was 20.98 per cent from initial (133.58 kg ha-1) to final crop (summer 2019) (105.55 kg ha-1).
本试验于2017年收获季、2018年夏季、2018年夏季和2019年夏季在Mandya VC农场区域农业研究站进行，研究了磷矿肥堆肥对手指粟-豇豆种植顺序收获后土壤养分状况的影响。在田间试验开始之前，三种不同的堆肥，即城市固体废物堆肥(USWC)，蚯蚓堆肥和农场院子粪便(FYM)用5%的磷肥进行强化。田间试验包括11种处理组合，包括推荐的N和K，以及通过不同水平的强化堆肥的P。试验采用RCBD设计，3个重复，试验作物为谷子和豇豆。试验点初始P2O5含量很高(133.58 kg ha-1)。结果表明，施用推荐氮和通过富集USWC (T5)提供的K + 75% P，在汇总数据中，谷子和豇豆的有机碳含量分别显著提高(0.56%和0.58%)。谷子和豇豆T5的有效氮(241.94和224.86 kg ha-1)、P2O5(138.69和120.99 kg ha-1)和K2O(153.92和135.31 kg ha-1)均显著高于对照。同样，在混合平均中，谷子和豇豆中分别施用推荐氮和K + 75%磷处理的交换性Ca[4.15和4.04 C mol (P+) kg-1]和Mg[2.16和2.05 C mol (P+) kg-1]显著高于富集蚯蚓堆肥(T8)。有效P2O5从初始(133.58 kg ha-1)到最终作物(2019年夏季)(105.55 kg ha-1)减少了20.98%。

Introduction: Soil erodibility is an important factor in understanding the erosion that takes place in a territory. This is a parameter that can behave erratically in small spaces, but that describes a trend in larger spaces. Aim: Determine the K factor of soil erodibility in the La Villa-Panama river basin. Place and Duration of Study: La Villa River Basin-Azuero Peninsula, Panama. 2010-2012. Methodology: 98 points of the La Villa river watershed were sampled. Factor K was calculated using the adaptation to the sol-erodibility nomogram. The percentage of organic matter, structure class (in the field), permeability (combination permeameter) and the percentages of sand, silt and very fine sand (Bouyoucos method) were determined. To obtain the most complete information possible on the distribution of erodibility, a superficial interpolation of the point values corresponding to the soil samples taken was carried out. The software used was Arcview 3.3 and the Spatial Analyst extension. The interpolation method was IDW (Inverse Distance Weight). The erodibility values were categorized into seven intervals in such a way that it was possible to observe the differences on the map. Results: The erodibility values were influenced by the content of organic matter and coarse particles (percentage of sand and silt + very fine sand) of the soil. In the province of Herrera, 86% of the land surface and 76% in the province of Los Santos presents susceptibility to erosion in the ranges of 0.032 to 0.043 Ton ha h ha-1 Mj-1 mm-1. Conclusion: The results indicate that 80% of the soils of the La Villa river basin present a moderately high erodibility factor, with the highest values being registered in the upper middle zone.

A field experiment was conducted at Zonal Agricultural Research Station, Gandhi Krishi vigyana Kendra, Bengaluru during kharif-2017 and 2018 to study the influence of zeolite application on growth and yield of finger millet crop. The pooled analysis showed significantly higher plant height recorded in the treatment which received zeolite 50 kg ha-1 +125 per cent RDF (Recommended dose of fertilizer) which was at par with the treatment which received zeolite 50 kg ha-1 +100 per cent RDF in 30, 60, 90 and at Harvest stage. The number of tillers per hill (3.44), total dry matter production (41.67 g hill-1), number of fingers per ear head (5.95), straw yield (36.07 q ha-1) and grain yield (48.00 q ha-1) was recorded in the treatment received zeolite 50 kg ha-1 +125 per cent RDF which was at par with the treatment which received zeolite 50 kg ha-1 +100 per cent RDF in pooled analysis.

Many tropical and subtropical soils are low in phosphorus. This is partly because of excessive weathering, high phosphorous (P) fixation rates, and low P levels in soil parent materials. Continuous removal of P from soils by crops, coupled with limited application of P fertilizers, is also among the contributing factors for low P in soils. Phosphorus is among the most limiting macronutrient in rice (Oryza sativa L.) production. This study was conducted to evaluate the suitability of bat guano collected from Kisarawe (BGK-A and BGK-B) and Sukumawera caves (BGS) in Tanzania. The screen-house experiment at the Sokoine University of Agriculture was designed as a 4 × 6 factorial experiment conducted as a randomized complete block design (RCBD). Guano and triple superphosphate (TSP) were used as standard fertilizer at six P application rates. The yield of rice in response to applied TSP was comparable to applied guano but in the order TSP > BGK-A > BGS > BGK-B. All parameters increased with an increase in applied amounts of P from guano and TSP. Besides this study revealed the significant (P = .05) interaction between P sources and P rates on plant height (PH), micronutrient concentration and dry matter (DM). The study showed the correlation between grain yield (GY) and other crop components of dry matter (DM), the number of panicles (NP), Panicle height (PAH), plant height (PH) and number of tillers (NT). A significant and positive correlation was found for the GY-DM (r = 0.58, P = .05), GY-PAH (r = 0.65, P < .001), and GY-NT (r = 0.420, P = 0.1). But strong positive correlation was found between GY-PH (r = 0.76, P < .001) and GY-NP (r = 0.84, P < .001). It was concluded that studied guanos can be used as an alternative source of P, especially for smallholder farmers.
许多热带和亚热带土壤的磷含量很低。这部分是由于过度风化、高磷固定率和土壤母质中磷含量低所致。作物对土壤中磷的持续去除，加上磷肥的施用有限，也是土壤中磷含量低的因素之一。磷是水稻(Oryza sativa L.)生产中最具限制性的大量营养元素之一。本研究旨在评价坦桑尼亚Kisarawe洞穴(BGK-A和BGK-B)和Sukumawera洞穴(BGS)收集的蝙蝠鸟粪的适宜性。索科因农业大学筛选室试验设计为4 × 6因子试验，采用随机完全区组设计(RCBD)。以鸟粪和三价过磷酸钙(TSP)为标准肥，施磷量为6倍。施用TSP对水稻产量的响应与施用鸟粪相当，但顺序为TSP > BGK-A > BGS > BGK-B。各参数均随鸟粪磷和总磷施用量的增加而增加。此外，磷源与施磷率在株高(PH)、微量元素浓度和干物质(DM)上存在显著的交互作用(P = 0.05)。研究表明，籽粒产量(GY)与干物质(DM)、穗数(NP)、穗高(PAH)、株高(PH)和分蘖数(NT)等作物成分存在相关性。GY-DM (r = 0.58, P = 0.05)、GY-PAH (r = 0.65, P < 0.001)、GY-NT (r = 0.420, P = 0.1)呈显著正相关。而GY-PH (r = 0.76, P < .001)与GY-NP (r = 0.84, P < .001)呈正相关。综上所述，所研究的鸟粪可作为磷的替代来源，特别是对小农而言。

A field experiment was conducted in the central farm, Regional Research and Technology Transfer Station, Coastal Zone OUAT, Bhubaneswar, Odisha, India during kharif 2020 using cv-Lalat variety of Rice. The experiment was laid out in randomized block design (RBD) with ten treatments and three replications. In this experiment BOF (Basic Oxygen Furnace) slag was used as a source of silica for application to rice crop. 200, 300 and 400 kg SiO2/ha was applied in combination with 50% STD (Soil Test Dose) and 75% STD to assess the efficacy of Silica with reduction in fertilizer dose by 50% and 25%. It was shown that increase in number of effective tillers (7.8) per plant and length of the panicle (25.8 cm), but no significant increase was marked in case of 1000 grain weight (gm.) over control. In case of grain yield, straw yield and harvest index, 100% STD (T4) registered maximum (36.9q/ha) grain yield which was 29.4% more than that of control. Of course, grain yield in case of T9 i.e., 75% STD+300 kg SiO2/ha was at par 36.2q/ha indicated efficacy of silica application by reducing fertilizer dose. Harvest index was not affected by Si treatments. However, maximum HI (0.478) was observed in T9. Available N, P, K and S status in post-harvest soil was increased due to application of silica along with fertilizer over control indicated better availability of nutrients which plays a vital role in increasing production and productivity of rice. The study revealed that the DTPA extractable Fe and Mn content decreased, and Cu and Zn content increased with increased application of silica. Though 100% STD (T4) was found to be very effective as compared to other treatments but 75% STD + 300kgSiO2/ha was also equally effective so far as yield, growth attributing characters, available nutrient status of paddy.
2020年秋季，在印度奥里萨邦布巴内斯瓦尔沿海地区OUAT区域研究和技术转移站中心农场，利用cv-Lalat水稻品种进行了田间试验。试验采用随机区组设计(RBD)， 10个处理，3个重复。本试验以碱性氧炉炉渣为原料，将二氧化硅应用于水稻生产。施用200、300和400 kg SiO2/ha，与50% STD(土壤试验剂量)和75% STD联合施用，分别减少50%和25%的施肥量，评估二氧化硅的效果。结果表明，在1000粒重(gm)处理下，单株有效分蘖数(7.8个)和穗长(25.8 cm)均有显著增加，但未见显著增加。在籽粒产量、秸秆产量和收获指数方面，100% STD (T4)产量最高(36.9q/ha)，比对照增产29.4%。当然，在T9条件下，即75% STD+300 kg SiO2/ha的粮食产量为36.2q/ha，表明通过减少肥料剂量施用二氧化硅的效果。Si处理对收获指数无显著影响。然而，在T9观察到最大的HI(0.478)。稻谷收获后土壤有效氮、磷、钾、硫含量增加，氮素有效利用率提高，对水稻产量和生产力的提高起着重要作用。研究发现，随着二氧化硅用量的增加，DTPA可萃取铁、锰含量降低，铜、锌含量增加。虽然与其他处理相比，100% STD (T4)处理非常有效，但75% STD + 300kgSiO2/ha对水稻产量、生长性状、速效养分状况也同样有效。
