A comparative study was carried out to assess the nature and characteristics of soils from two agro-ecological sub regions (AESU and AESR) from two states of South India. Using sentinel-2 satellite data, google imagery and top sheet, a detailed soil survey was taken up in AESU and AESR. Major soils from upland as well as from lowlands were compared to assess the soils heterogeneity. Results showed that there was a high heterogeneity between properties of soils AESU and AESR. Variability existed in climatic conditions (tropical humid region in AESU and semiarid condition in AESR), physiographic (valley plain to gently, very gently, moderate, steep and very steep slopes in AESU and levelled to gently and very gently slopes in AESR ), geology (charnockite and granite gneiss in AESU whereas granite gneiss in AESR), land use (rubber, paddy, coconut in AESU and paddy, mango, pigeon pea, groundnut in AESR), soil classification (Ultisols and Alfisols in AESU whereas Alfisols and Inceptisols in AESR) and land capability (soil and water conservation measures must in AESU and slope was manageable with agronomic management practices in AESR). Soils varied in texture (clay, sandy clay and clay loam in AESU whereas sandy clay loam to sandy loam in AESR), consistency and depth of soils (shallow to very deep in AESU and shallow to deep in AESR). Clay content (32.9 to 63.5%) was dominant fraction in AESU whereas sand (52.1 to 72.1%) was in AESR. Soil acidity (strongly acid to very strongly acid) was a major problem (both hydrogen and aluminium saturation) in AESU whereas slightly acidic to neutral and slightly alkaline in AESR. Organic carbon content was high (up to 25.9 gkg-1) in AESU whereas it was up to 10.0 gkg-1 in AESR. Base saturation was <35% in AESU and >75% up to 100% in AESR. Calcium carbonate equivalent is >5% in AESR and not a problem in AESU. CEC was low (<12 cmol (p+) kg–1) in AESU and good (>12 cmol (p +) kg–1) in AESR.

A field experiment was conducted during 2017-18 at Crop Research Centre, G.B.P.U.A.&T., Pantnagar with the objective of developing fertilizer adjustment equations and quantifying doses for achieving targeted yield of hybrid maize (Zea mays L.) by using STCR approach. Response of hybrid maize to four levels of N, P and K and two levels of FYM under different fertility levels was studied. Nutrient requirements (NR) were reported as 2.17, 0.46 and 2.74 kg q-1 for N, P and K, respectively. The contribution of nutrients N, P, and K from fertilizers (%CF) was found as 58.2, 62.7 and 420.4% , from soil (%CS) as 33.1, 26.8 and 22.7%, from organic matter FYM (%CFYM) as 45.2, 14.4 and 239.4% , from fertilizer with FYM (%CF*) as 62.4, 63.5 and 427.6%, respectively. Fertilizer adjustment equations and ready reckoners were developed with and without FYM for different targeted yield and soil test values of N, P and K. It was observed that response of hybrid maize to N, P and K fertilizers was higher when integrated with FYM application as compared to N,P and K alone. The average saving of fertilizer by application of 10 tonnes FYM was 24.52 kg ha-1 N, 7.11 kg ha-1 P and 3.50 kg ha-1 K within the range of soil test value and yield targets on Mollisol.
2017- 2018年在g.b.p.u.a.t.&t作物研究中心进行了田间试验。目的是利用STCR方法建立杂交玉米(Zea mays L.)实现目标产量的肥料调整方程和定量剂量。研究了杂交玉米在不同肥力水平下对4个氮、磷、钾水平和2个氮肥水平的响应。氮、磷和钾的养分需要量(NR)分别为2.17、0.46和2.74 kg q-1。肥料(%CF)对N、P、K的贡献分别为58.2%、62.7%和420.4%，土壤(%CS)对N、P、K的贡献分别为33.1%、26.8%和22.7%，有机质FYM (%CFYM)对N、P、K的贡献分别为45.2%、14.4%和239.4%，含FYM (%CF*)的肥料对N、P、K的贡献分别为62.4、63.5和427.6%。针对不同的N、P、K目标产量和土壤试验值，分别建立了施用和不施用FYM的肥料调整方程和计算公式。结果表明，与单独施用N、P、K相比，混合施用FYM的杂交玉米对N、P、K的响应更高。在Mollisol土壤试验值和产量指标范围内，施用10吨FYM平均节约化肥24.52 kg hm -1 N、7.11 kg hm -1 P和3.50 kg hm -1 K。

The investigations were carried out to evaluate the 64 genotypes (28 F1, 28 F2 and 8 parental lines) of pumpkin ((Cucurbita moschata Duch. Ex Poir.)’at Department of Vegetable Science, Kalyanpur, CSA. University of Agriculture and Technology, Kanpur (U.P.) during Zaid 2021. The experiments were laid out in randomized complete block design with three replications. The data were recorded for 19 characters including total fruit yield per plant and its component traits. Analysis of variance showed that there was highly significant variation for all the characters studied. In F1 generation, the highest genotypic as well as phenotypic coefficients of variations were observed for fruit yield/plant. In F2 generation, the highest genotypic as well as phenotypic coefficients of variation were observed for fruit yield/plant and average fruit weight. In F1, high heritability in narrow sense coupled with high genetic advance as per cent of mean were observed for equatorial circumference of fruit, polar circumference of fruit and seeds/fruit while in F2, high heritability coupled with high genetic advance as per cent of mean were observed for seeds/fruit. High estimate of heritability along with high genetic advance in per cent of mean provides good scope for further improvement in advance generations.

To investigate the efficacy of various doses of plant growth regulators on vegetative growth and pod yield of broad bean (Vicia faba L.), a field experiment was accomplished at Vegetable Research Farm, B.H.U., Varanasi during the winter season of 2019-20. Ten treatments were evaluated in randomized block design with three replications. Results indicated that the growth parameters like plant height, number of branches/plant significantly increased with foliar spray of gibberellic acid followed by NAA and salicylic acid. The yield attributes like pod width, fresh pod weight, number of pods/plant as well as fresh pod yield significantly enhanced by NAA followed by gibberellic acid and salicylic acid with various concentrations, respectively. The foliar spraying of 120 ppm GA3 tended to produce plant with maximum height (116.4 cm), number of branches/plant (6.3), pod length (7.5 cm), number of seeds/pod (4.6) as well as early 50 % flowering (57.3 days) whereas, spraying of 40 ppm NAA exhibited the maximum pod width (1.3 cm), fresh pod weight (4.6 g), number of pods/plant (87.5) as well as fresh pod yield (105.0 q ha-1) as compared to other treatments. The maximum net return (Rs. 337326.5 ha-1) was recorded with 40 ppm NAA with B: C ratio of 3.65 followed by 30 ppm NAA and 20 ppm NAA. The lowest net income (Rs. 162382.5 ha-1) and B: C ratio (1.76) was obtained from control. The spraying of NAA was found superior in terms of yield and yield attributes as well as benefit cost ratio followed by GA3 and salicylic acid.

A field study was conducted during Kuruvai season of 2020 to evaluate the efficacy of new generation herbicides at Pattathikadu village, Karambakudi Taluk, Pudukkottai district, Tamil Nadu. Eleven treatments were evaluated in RBD design and replicated thrice. Early post emergence application of bispyribac sodium 10 % SC @ 200 ml ha-1 on 15 DAS fb hand weeding on 40 DAS suppressed both weed population (20.16 m-2)andweed dry matter production (33.59 kg ha-1) and recorded highest weed control index (90.70 %) at 60 DAS over unweeded check. Growth and yield attributes of ricewere significantly improved with early post emergence application of bispyribac sodium 10 % SC @ 200 ml ha-1 on 15 DAS fb hand weeding on 40 DAS. Growth attributes viz., plant height (48.80, 78.56 cm at 30, 60 DAS and 94.54 cm at harvest respectively), leaf area index at flowering stage (6.89), number of panicle m-2 (434.14), number of tillers hill-1 (26.21), dry matter production (6,946, 11,917 and 13,646 kg ha-1 at 30, 60 DAS and harvest respectively) and yield attributes viz., number of filled grain panicle-1 (94.14)and grain (6540 kg ha-1) and straw (8522 kg ha-1) yieldswere recorded under early post emergence application of bispyribac sodium 10 % SC @ 200 ml ha-1 on 15 DAS fb hand weeding on 40 DAS hence appeared to be a viable strategy for weed control in direct seeded rice.
在2020年库鲁瓦伊季节，在泰米尔纳德邦Pudukkottai县Karambakudi Taluk的Pattathikadu村进行了一项实地研究，以评估新一代除草剂的效果。在RBD设计中评估了11个处理，并重复了3次。苗期早期在15 DAS fb上施用双嘧菌酯钠10% SC @ 200 ml ha-1，在40 DAS上进行手除草，抑制了杂草数量(20.16 m-2)和杂草干物质产量(33.59 kg ha-1)，并且在60 DAS未除草时记录了最高的杂草控制指数(90.70%)。苗期早期在15株DAS上施用10% SC @ 200 ml ha-1双吡虫胺钠，可显著改善水稻的生长和产量特性。生长属性，即株高(收获时分别为48.80、78.56 cm, 30、60 DAS和94.54 cm)，开花期叶面积指数(6.89)，穗数m-2(434.14)，分蘖数hill-1(26.21)，干物质产量(30、60 DAS和收获时分别为6,946、11,917和13,646 kg ha-1)和产量属性，即在15株DAS上，在出苗期早期施用双嘧菌酯钠10% SC @ 200 ml ha-1，记录了灌浆穗数(94.14)、籽粒(6540 kg ha-1)和秸秆(8522 kg ha-1)产量，因此在40株DAS上进行手除草似乎是一种可行的直接播种水稻杂草控制策略。

The field experiment was conducted during Kharif season of 2018 at NDRI, Karnal to study the influence of various sources of potassium on soil microbial population, enzymatic activities and yield of fodder crops. The experiment was laid out in the split-plot design with 16 treatment combinations and replicated thrice. In the main plot treatment, two fodder crops, viz., maize (Zea mays) and sugargraze (Sorghum bicolor L. × Sweet sorghum × Sorghum sudanese L.), were included while potassium treatments were executed under subplot treatment. The results revealed that, application of K50 + KSB + 2% KNO3 had a significant influence on biomass production and 30.3 and 22.4% green and dry fodder yield, enhancement was recorded over control. Soil microbial biomass carbon (MBC) was not significantly affected by fodder maize and sugargraze crops at 30 DAS and harvest. However, potassium application had significant influence on soil MBC and a higher values (167 and 185 µg/g dry soil) were recorded with K25 + KSB + 2% KNO3 treatment at 30 DAS and harvest over control, respectively.

This study was conducted at Engineering farm, Navsari Agricultural University, Navsari, India, during winter 2016-17 using sorghum crop (Sorghum bicolar) to examine the effect of three land leveling (control or unleveled, conventional land leveling and leveling with laser guided land leveler) and three planting systems (ridge and furrow, double row bed planting and triple row bed planting). The laser guided land leveler significantly improved the growth attributes of sorghum as compared to the control whereas the growth attributes were recorded highest under double row bed planting. The highest yield attributes were recorded in laser guided land leveler. The best results of sorghum yield attributes were recorded under double row bed planting. In land leveling, laser guided land leveler significantly improved yield of sorghum (grain and fodder) as compared to control. Whereas, maximum sorghum yield was obtained under double row bed planting over rest planting system. The soil moisture distribution, water saving and water use efficiency were improved under laser guided land leveler with double row bed planting over rest of the treatments. The highest gross return, net return and benefit: cost ratio were obtained under laser guided land leveler with double row bed planting over rest of the treatments.

Field experiments were conducted at Bhubaneswar, Odisha during kharif seasons of 2018 and 2019 to study the growth behavior of rice varieties under nutrient management practices. Six treatment combinations comprising of three nutrient management (100% Soil Test Based Nitrogen Recommendation (STBNR), 75% STBNR + in situ green manuring (dhaincha) and 50% STBNR + in situ green manuring of dhaincha) and two rice varieties (Manaswinee of 125d duration and Hasanta of 145d duration) were tried in randomized complete block design (RCBD) with four replications. The results showed that crop growth rate (CGR) was significantly influenced by both nutrient management practices and varieties. Pooled over the years, application of 75% STBNR + green manuring of dhaincha exhibited the maximum CGR of 11.33 and 20.80 g/m2/day during 30-60 and 60-90 DAT, respectively and which were superior to 100% STBNR and 50% STBNR + green manuring of dhaincha. Similarly, rice cv. ‘Hasanta’ recorded CGR of 10.98 and 20.42 g/m2/day during 30-60 and 60-90 DAT, respectively, which were higher over cv. ‘Manaswinee’. The maximum relative growth rate (RGR) of 23.77 mg/g/day was registered with 50% STBNR + green manuring of dhaincha, being at par with 75% STBNR + green manuring of dhaincha during 60-90 DAT. Application of 75% STBNR + green manuring of dhaincha recorded the maximum Net assimilation rate (NAR) of 3.41 and 4.26 g/m2 leaf area/day during 30-60 and 60-90 DAT, respectively. Both cultivars were equally effective for RGR and NAR. The treatment trend for physiological indices led to higher grain yield under 75% STBNR + green manuring of dhaincha among nutrient management practices and cv. ‘Hasanta’ between rice varieties. Grain yield and the three physiological indices were positively correlated, but the correlation coefficient values were significant for CGR and NAR.
