An experiment was undertaken to evaluate the genetic variability, coefficient of variation, heritability, genetic advance and correlation coefficient among indigenous okra accessions based on morphological parameters. Ten okra accessions collected from different parts of Garo Hills regions of Meghalaya were planted during 2019 at NEHU Tura campus, Meghalaya in random block design with three replications. The Analysis of variance exhibited significant differences among the accession for different characters evaluated. The phenotypic coefficient of variance (PCV) was predominantly superior to their corresponding genotypic coefficient of variance resulting the role of environmental aspects. A high heritability in relation with high genetic advance as the percentage of mean value was observed for plant height. The Correlation studies between various quantitative characters exhibited significant association between parameters. Plant height, number of fruits per plant showed highly positive significant association with fruit yield per plant both at phenotypic and genotypic level. On the basis of mean performance for fruit yield and its component characters from the present investigation 5 superior okra germplasm lines namely T-4, T-6, T-7, T-8 and T-10 were selected as superior and most promising genotypes for the crop improvement programmed in okra.

An experiment was conducted to study the effect of different planting dates, spacing and training systems on growth and yield of cucumber (Cucumis sativus L.) under naturally ventilated polyhouseduring the off season 2017 at the Research farm, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. The treatment comprised of three planting dates, two spacing and three training system were evaluated in factorial randomized block design (FRBD) with three replications. Among the dates of transplanting, 2nd fortnight of March proved significantly superior to 1stfortnight of March and 1st fortnight of April with respect of vine length (174.2 cm), days to initiation of first female flower (13.5), days to 50% flowering (26.3 days), number of days to first picking (34.6 days). The crop transplanted in first fortnight of March produced the plant with significantly smaller internodal length (9.3 cm) and prolonged harvest duration (59.3 days). Plants grown at wider spacing of 75 cm x 30 cm resulted in significantly smaller internodal length (9.4 cm) and took lesser number of days for initiation of first female flower (14.1 days), days to 50% flowering (28.5 days), days to first picking (36.4 days) and harvest duration (53.9 days) whereas narrow spacing of 60 cm x 30 cm produced significantly higher vine length (171.5 cm) regards to the number of shoots per plants, plants trained to two shoots produced significantly smaller internodal length (9.0 cm), took lesser number of days to 50% flowering (26.6 days), number of days to first picking (36.3 days) while significantly higher vine length (172.1 cm) and prolonged harvest duration (58.8 days) was also recorded with two shoots. In case of fruit yield plants with three shoots, spaced at 60 cm x 30 cm in the 1st fortnight of March recorded significantly higher fruit yield. Interaction effect was found significant for vine length, number of days to first picking and harvest duration.

The field experiment was conducted during rabi season in 2017-18 and 2018-19 at the Agronomy Research Farm, A.N.D. University of Agriculture & Technology, Kumarganj, (Ayodhya)to find out the effect of weed management practices on productivity and economics of mustard (Brassica juncea L.). Fifteen treatments were evaluated in randomized block design with three replications. Two hand weedings at 20 and 40 DAS recorded significantly lowest population and dry weight of weeds as compared to rest of the treatments during both the years. Among the herbicides combination, pendimethalin (PE) @ 1000 g ha-1 applied either with hand weeding at 40 DAS or paddy straw mulch @ 10 t ha-1 at 2-3 DAS recorded the lowest weed density and dry weight m-2 followed by metribuzin (PE) @ 175 g ha-1 either with hand weeding at 40 DAS or paddy straw mulch @ 10 t ha-1 at 2-3 DAS. Weedy check till maturity recorded significantly highest density and dry weight of weeds as compared to rest of the treatments during both the years. Pre-emergence spray of pendimethalin (PE) @ 1000 g ha-1 + hand weeding at 40 DAS being at par with two hand weeding at 20 and 40 DAS but recorded highest values of all yield attributes and yields as compared to rest of the treatments. The increase in grain yield due to pendimethalin (PE) @ 1000 g ha-1 + hand weeding at 40 DAS was recorded to the tune of 10.4% over pendimethalin (PE) @ 1000 g ha-1 + paddy straw mulch @ 10 t ha-1 at 2-3 DAS. The yield losses due to weedy check till maturity was recorded to the tune of 58.2%, 53.3% and 43.3% as compared to two hand weeding applied at 20 and 40 DAS, pendimethalin (PE) @ 1000 g ha-1 + hand weeding at 40 DAS, and pendimethalin (PE) @ 1000 g ha-1 + paddy straw mulch @ 10 t ha-1 at 2-3 DAS, respectively. The highest net income (Rs. 57394 ha-1) and B:C ratio (1.5) was recorded with pendimethalin (PE) @ 1000 g ha-1+ hand weeding at 40 DAS which was followed by two hand weeding at 20 and 40 DAS with net income of Rs. 55485 ha-1 and B:C ratio 1.49.
本试验于2017-18和2018-19两季在阿约提亚库马甘吉农学研究农场进行，旨在了解杂草管理措施对芥菜(Brassica juncea L.)产量和经济效益的影响。15个处理采用随机区组设计，3个重复。与其他处理相比，在这两年中，20和40 DAS的双手除草记录了显著最低的杂草种群和干重。在除草剂组合中，手除草40 DAS或稻田秸秆覆盖10 t ha-1、2-3 DAS时施用1000 g ha-1的戊二甲基甲烷(PE)的杂草密度和干重m-2最低，其次是手除草40 DAS或稻田秸秆覆盖10 t ha-1、2-3 DAS时施用175 g ha-1的甲霉嗪(PE)。在这两年中，与其他处理相比，杂草检查至成熟记录了显著最高的杂草密度和干重。拔苗期前喷施1000克/公顷(PE) + 40 DAS时的手除草与20和40 DAS时的双手除草相同，但与其他处理相比，所有产量属性和产量都记录了最高值。经记录，在2-3个稻谷时，喷施喷施1000 g hm -1 +手除草，比喷施1000 g hm -1 +稻田秸秆覆盖10 t hm -1，增产10.4%。与20和40 DAS时两次手除草、40 DAS时喷喷喷甲醚(PE) 1000 g ha-1 +手除草和2-3 DAS时喷喷喷甲醚(PE) 1000 g ha-1 +稻田秸秆覆盖10 t ha-1相比，杂草检查至成熟期造成的产量损失分别为58.2%、53.3%和43.3%。在40 DAS时，喷二甲基甲烷(PE) @ 1000 g ha-1+手除草的净收入最高，为57394卢比，B:C比为1.5，其次是20和40 DAS时的双手除草，净收入为55485卢比，B:C比为1.49。

A field experiment was performed to study the effect of Zn sources combined with Zn solubilising microorganisms-ZSM (Acinetobacter calcoaceticus + Pantoea agglomerans) on yield, nutrient uptake, phytic acid and economics of rice (Oryza sativa L.). The experiment was conducted for two consecutive years (2018 and 2019) at Banaras Hindu University, Varanasi. The experiment was designed in randomized block design with twelve treatments replicated thrice. The data indicated that 25 kg ZnSO4.7H2O ha-1 + ZSM significantly increased tillers over other treatments, but 9.8 kg ZnO ha-1 + ZSM improved panicle length, filled spikelet panicle 1 and test weight. The phytic acid content in rice was found superior in control treatment (6.5 g kg-1), whereas significantly reduced in 25 kg ZnSO4.7H2O ha-1+ ZSM treatment. Moreover, the maximum grain yield (5.01 t ha-1), straw yield (7.85 t ha-1), net return (Rs 58.94 ×103 ha-1) and benefit: cost ratio (1.88) was recorded with 9.8 kg ZnO ha-1 + ZSM. The higher uptake of nitrogen and potassium was recorded in 25 kg ZnSO4.7H2O ha-1+ ZSM treated plot. However, phosphorous uptake was maximum in control. The maximum total Zn uptake (1364.8 g ha-1) was documented with 9.8 kg ZnO ha-1 + ZSM + cow dung.
通过田间试验，研究了锌源与增锌菌zsm (accoaceticus + Pantoea agglomerans)联合施用对水稻产量、养分吸收、植酸和经济的影响。该实验连续两年(2018年和2019年)在瓦拉纳西的巴纳拉斯印度教大学进行。试验采用随机区组设计，12个处理重复3次。结果表明，与其他处理相比，25 kg ZnSO4.7H2O ha-1 + ZSM处理显著增加了分蘖数，而9.8 kg ZnO ha-1 + ZSM处理增加了穗长、穗1填充和试验质量。水稻植酸含量在对照处理(6.5 g kg-1)中较高，而在25 kg ZnSO4.7H2O ha-1+ ZSM处理中显著降低。此外，9.8 kg ZnO ha-1 + ZSM可获得最高籽粒产量(5.01 t ha-1)、秸秆产量(7.85 t ha-1)、净收益(Rs 58.94 ×103 ha-1)和效益成本比(1.88)。25 kg ZnSO4.7H2O ha-1+ ZSM处理对氮、钾的吸收量较高。而对照的磷吸收量最大。在9.8 kg ZnO ha-1 + ZSM +牛粪条件下，总锌吸收量最大(1364.8 g ha-1)。

A long-term field experiment started in 1995 on coarse loamy soil at CCS Haryana Agricultural University, Hisar (India) was selected to examine the impact of organic manures and fertilizers on soluble salts content in soil and mineral composition of wheat (Triticum aestivum). The results revealed that continuous application of organic manures (FYM, poultry manure and pressmud) alone or in combination with fertilizers significantly increased the content of soluble ions (Na+, K+, Ca2+, Mg2+, Cl-, SO42-, HCO3- and CO32-) in soil. Water soluble CO32- content showed irregular trend among various treatments. The amounts of soluble ions were found highest in FYM treated plots as compared to poultry manures and pressmud which resulted in higher soil EC of these plots. Increased availability of these soluble ions in soil also increased the plant uptake and accumulated in plant tissues. The Na, Ca, Mg and Cl contents in wheat grain and straw were higher when organic manures were applied alone, while K and S contents were found higher in the plots receiving combined application of manures and fertilizers.

The suitability of soilless growing media compositions was evaluated for quality flower production of potted Chrysanthemum morifolium Ramat cultivar Anmol at Punjab Agricultural University, Ludhiana during 2014-16. The rotted cuttings were grown in six different potted media compositions – control: garden soil + (farmyard manure (FYM) 2: 1), cocopeat + FYM (1: 1), cocopeat + FYM (2: 1), vermiculite + FYM (1: 1), vermiculite + FYM (2: 1) and cocopeat + vermiculite + FYM (1: 1: 1). The results revealed that the cocopeat + FYM (2:1) exhibited maximum plant height, number of leaves and root suckers per plant whereas; vermiculite + FYM (2:1) gave highest flower diameter and duration of flowering. The days to bud appearance, colour break stage and full bloom were delayed in cocopeat based media. However, significant vegetative growth with better flowering time and quality was obtained in cocopeat + vermiculite t + FYM (1:1:1). Thus for sustained quality flower production of potted Chrysanthemum cv. Anmol, cocopeat + vermiculite + FYM (1:1:1) media was ideal with better plant morphological development.

Nutrient use efficiency (NUE) is a critical parameter for determining sustainability of crop production systems. Under the current fertilization practices involving conventional fertilizers, the NUE ranges 30–40% for N-fertilizers and 18–20% for P-based fertilizers. Apparently, only a fraction of these nutrients is available for crop growth and yield formation. In contrast, a relevant amount of fertilizers is released into the environment annually, resulting in eutrophication and groundwater contamination that threatens environmental resources, public health, and economic investments. Thus, it will be essential to introduce agro technological innovations and revolutionary agri inputs. Nanotechnologies have the potential to produce a significant boost in crop yield along with improvement of food production systems. This innovation can lead to more precise application of nutrients along with saving of the nutrients. This review provides a critical view of the latest advances in nano fertilizer research, mainly referring to nano-hydroxyapatite based nanoparticles and other alternative nanotech based nanofertilizers.

The extent of heterosis for eleven traits, including seed yield per plant, was investigated in sesame. During summer 2019, 21 F1 crosses from 7 parents (GT 03, SKT 1501, AT 413, AT 383, AT 338, AT 307 and AT 345) were developed by using a diallel mating (7 x 7) design that excluded reciprocals. In Kharif 2019, twenty-nine entries (genotypes) which including a check (GT-04), seven parents, and their 21 F1 hybrids were evaluated in randomized block design (RBD) with three replication at the 'Agronomy Instructional Farm, S. D. Agricultural University, Sardarkrushinagar, Gujarat'. The highly significant and positive standard heterosis with high per se performance for seed yield per plant and some of its component traits were recorded in the crosses viz GT 03 x SKT 1501, GT 03 x AT 307, GT 03 x AT 345, SKT 1501 x AT 307, AT 413 x AT 307, and AT 307 x AT 345. Five hybrids showed highly significant positive heterobeltiosis for seed yield per plant, while six hybrids showed highly significant positive standard heterosis for seed yield per plant. In Sesame, the current research shows that there is a lot of potential for isolating pure lines from heterotic F1s progenies as well as commercialising heterosis.

The study on efficacy of fungicides against Alternaria blight disease of linseed caused by Alternaria lini was conducted at Research farm of Bihar agricultural university, Sabour, Bhagalpur (Bihar) during Rabi season of 2020-21 to select suitable fungicides against this disease. Six fungicides were evaluated in vitro and in vivo condition. The results revealed that all the tested fungicides showed significantly better performance to minimize the Alternaria blight disease over control. Among the tested fungicides, Propiconazole 25 EC proved the best at all the concentrations (100, 150 and 200 ppm) as it showed 100% of mycelial growth inhibition over control. In the field condition too, Propiconazole 25EC proved superior among all the fungicides with the lowest disease severity (10.66%). It showed the highest disease control over check (77.6 %) and also highest yield (884.33 kg ha-1) which was followed by Azoxystrobin 23%SC and Carbendazim 12% + Mancozeb 63% WP.
在2020- 2021年拉比季节，在比哈尔邦农业大学Sabour研究农场对亚麻种子白疫病的杀菌剂效果进行了研究，以选择适合的杀菌剂。对6种杀菌剂进行了体外和体内评价。结果表明，所有被试杀菌剂在减少白叶枯病方面的效果都明显优于对照。在不同浓度(100、150和200 ppm)下，丙环唑25 EC对菌丝生长的抑制效果均为100%。在田间条件下，丙环唑25EC杀菌剂效果较好，病害严重程度最低(10.66%)。其中防病率最高(77.6%)，产量最高(884.33 kg hm -1)，其次为氮唑菌酯23%SC和多菌灵12% +代森锰锌63% WP。

ABSTRACT Soil salinity and sodicity are the global problems and pose a serious threat to agriculture sustainability. The distribution of salt affected soils exist mostly under arid and semi-arid climates where rainfall is inadequate to leach salts from/out of the root zone. These soils have poor fertility, generally with low availability of nitrogen, calcium, zinc, iron and manganese. Therefore, judicious nutrients management on the principle of INM in these soils is as important as their reclamation. In these soils, crops respond differently to applied nutrients due to their diverse chemical composition impacting precipitation-dissolution reactions and adsorption-desorption kinetics. Nutrient transformation and loss mechanisms of applied nutrients are also affected by the magnitude of soil salinity and sodicity. The paper aims at discussing efficient nutrient management in salt affected soils for sustainable crop production.
