A field experiment was conducted during kharif seasons of 2016 and 2017 at the Research Farm, ICAR Research Complex for NEH Region, Nagaland Centre to study of the effect of planting geometry and weed management practices on maize (Zea mays L.) based intercropping system. The experiment was laid out in randomized block design with twelve treatments and replicated three times. The results revealed that different planting geometry patterns did not affect the growth and yield attributes at any stage of growth of maize. Growth attributes tended to increase with advancement of growth and maximum values were recorded at 90 DAS. The highest grain and stover yields of maize were recorded as 2.54 t ha-1 and 4.98 t ha-1 from the maize + soybean (2:2) planting geometry. Weed management practices had significant effect over weedy check on plant growth parameters, yield attributes, grain and stover yields except test weight of maize. The highest grain (2.87 t ha-1) and stover yields (5.55 t ha-1) of maize were recorded with two hand weedings at 20 and 40 DAS which was at par with pre-emergence application of pendimethalin @ 1.0 kg a.i.ha-1 + 1 HW at 30 DAS.
在2016年和2017年的丰收季节，在那加兰邦中心ICAR NEH地区综合研究中心的研究农场进行了一项田间试验，研究种植几何形状和杂草管理措施对玉米间作系统的影响。试验采用随机区组设计，12个处理，重复3次。结果表明，不同种植形态对玉米各生育期的生长和产量属性均无显著影响。随着生长的推进，生长属性趋于增加，最大值记录在90 DAS。玉米+大豆(2:2)种植的玉米籽粒和秸秆产量最高，分别为2.54 t hm -1和4.98 t hm -1。除玉米试验重外，杂草管理措施对植株生长参数、产量属性、籽粒和秸秆产量均有显著影响。20和40 DAS时两次手动除草，玉米籽粒最高(2.87 t hm -1)，秸秆产量最高(5.55 t hm -1)，与30 DAS时出苗前施用1 kg a.i.h -1 + 1 HW的二甲甲烷相当。

Zinc deficiency in soils and plants is the worldwide problem causing considerable yield reduction and indirectly affects human health due to its lesser concentration in the crop produces grown on zinc deficient soils. Hence to know the effect of zinc supply on the growth, clove yield and Zn accumulation, four field experiments were conducted with varied levels of zinc sulphate (0, 5, 10, 25, 37.5 and 50 kg ha-1) using garlic variety Ooty 1 as test crop on zinc deficient sandy loam soils during the Rabi season of 2018-19. Soils with deficient zinc availability showed better response to different levels of zinc sulphate and application of recommended NPK along with 10 kg zinc sulphate ha-1 was found sufficient and economical in increasing the clove yield of garlic by 20.6 per cent. The same treatment resulted in higher farm income with the benefit cost ratio of 3.28. Slight yield reduction (5-7%) at all the four farms was observed for the higher levels of zinc sulphate addition (37.5 and 50 kg ha-1). The highest soil Zn availability, zinc accumulation and uptake by garlic crop were obtained with the addition of 50 kg zinc sulphate ha-1. Although there was a higher variability in the garlic crop response to zinc levels at all the farms, zinc sulphate addition at different levels considerably improved the growth and yield of garlic and also increasing the zinc accumulation in cloves and plants on zinc deficient soils.
土壤和植物缺锌是一个世界性的问题，由于在缺锌土壤上生长的作物中锌的浓度较低，导致产量大幅下降，并间接影响人类健康。为了解锌供应对丁香生长、产量和锌积累的影响，于2018-19年拉比季以大蒜品种Ooty 1为试验作物，在缺锌砂壤土上进行了4个不同硫酸锌水平(0、5、10、25、37.5和50 kg ha-1)的田间试验。锌有效性不足的土壤对不同硫酸锌水平的响应较好，施用推荐氮磷钾和10公斤硫酸锌，可使大蒜的丁香产量提高20.6%。同样的处理可提高农场收入，效益成本比为3.28。在所有4个养殖场中，由于硫酸锌添加水平较高(37.5和50 kg hm -1)，产量略有下降(5-7%)。施用50 kg硫酸锌时，大蒜的土壤锌有效性、锌积累和吸收最高。虽然所有农场的大蒜作物对锌水平的反应存在较大的差异，但不同水平的硫酸锌添加显著改善了大蒜的生长和产量，也增加了缺锌土壤上丁香和植株的锌积累。

For characterization of soils, soils were collected from Jorhat and a Golaghat district during 2016-2017under different land uses systems i.e. bamboo, sugarcane, tea and rice. Results indicated that surface soils of different land use systems varied from greyish brown (10YR 5/2) to brownish yellow (10YR 6/8).The structure was found predominantly sub-angular blocky and loam to clay loam in texture. The soil soils of all horizons of bamboo, tea plantation and rice were extremely acidic (pH <4.5) except sugarcane horizons (strongly acidic pH 5.0-5.50).Soil cation exchange capacity(CEC) in bamboo, sugarcane, tea plantation and rice varied from 6.20 to 7.29 cmol (p+)/kg, 8.19 to 9.92 cmol (p+)/kg, 5.54 to 6.88 cmol (p+)/kg, and 6.99 to7.58 cmol (p+)/kg, respectively due to variation in clay content. Sugarcane and tea plantation soils showed clay alleviation with more than 1.2 times in sub-surface horizon over surface horizon with low base saturation <35%to place them in the Ultisol and classified as fine-loamy, mixed, hyperthermic family of Typic Hapludults.In bamboo plantation, the soil had cambic horizon with base saturation <35%and classified as coarse loamy, mixed, hyperthermic family of Typic Dystrudepts, whereas, in case of rice soil, the gleyed sub-surface horizon was observed with base saturation <35% and classified as loamy, mixed, hyperthermic, Typic Endoaquepts.The correlation coefficient (r) among physico-chemical of soil properties in profiles under different land use systems in upper Brahmaputra valley of Assam showed organic carbon was positively and significantly correlated with base saturation.

A field experiment was conducted to study the Influence of varieties and sowing dates on growth and yield of kharif groundnut (Arachis hypogaea L.) at Anand Agricultue University, Anand, during kharif season of 2019 and 2020. The treatments consisted of three dates of sowing viz; first date of sowing - onset of monsoon, second date of sowing - 10 days after onset of monsoon and third date of sowing - 20 days after onset of monsoon with three varieties viz; GG 20, GJG 34 and TAG 37A. The experiment was replicated four times in randomized block design (factorial). Results showed that first date of sowing (onset of monsoon) proved significantly superior to other dates of sowing in respect of growth and yield characters. Significantly high pod yield (2176 kg ha-1 and 1862 kg ha-1) was recorded during 2019 and 2020 under first date of sowing, respectively which was statistically at par with second date of sowing (1937 kg ha-1 and 1592 kg ha-1) and significantly higher than the third date of sowing (1614 kg ha-1 and 1369 kg ha-1). In case of crop sown at onset of monsoon, rainfall, soil moisture and mean temperature favorable during crop growing period showed significantly higher pod yield. Among the varieties, significantly higher pod yield (2043 and 1701 kg ha-1) was recorded under GG 20 over other varieties GJG 34 and TAG 3A during both the years. Hence, variety GG 20 was the promising ones in terms of growth and yield in middle Gujarat agro climatic zone. On an average, onset of monsoon (early sowing) gave 13.4% higher pod yield than 10 days after onset of monsoon sowing. GG 20 was recorded 6.8 % higher pod yield as compared to the GJG 34.
在阿南德农业大学进行了2019年和2020年秋冬季节花生品种和播期对花生生长和产量的影响的田间试验。这些处理包括三个播种日期，即;第一次播种日期-季风开始，第二次播种日期-季风开始后10天，第三次播种日期-季风开始后20天。GG 20, GJG 34和TAG 37A。试验采用随机区组设计(因子)重复4次。结果表明，第一播期(季风开始期)在生长和产量性状方面显著优于其他播期。2019年和2020年播期豆荚产量显著高(分别为2176 kg ha-1和1862 kg ha-1)，与播期2 (1937 kg ha-1和1592 kg ha-1)持平，显著高于播期3 (1614 kg ha-1和1369 kg ha-1)。在季风开始时播种的作物，在作物生育期降雨量、土壤湿度和平均温度有利的情况下，豆荚产量显著提高。其中，两年间，GG 20的豆荚产量(2043和1701 kg hm -1)均显著高于GJG 34和TAG 3A。因此，品种GG 20在古吉拉特邦中部农业气候带具有生长和产量方面的潜力。平均而言，季风开始(早播)使豆荚产量比季风开始后10天高13.4%。与gjg34相比，GG 20的豆荚产量高出6.8%。

A field experiment was conducted at research farm of AICRP for Dryland Agriculture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra), to assess the effect of potash management through gliricidia green leaves on soil fertility, nutrient balance and yield of rainfed cotton (Gossypium spp.) in Vertisols during kharif season of 2020. The results revealed that there was significant increase in hydraulic conductivity, organic carbon and available N, P, K of soil and decrease in soil pH, EC and bulk density in the gliricidia incorporated treatments as compared to control. The highest available N (211.1 kg ha-1), P (16.7 kg ha-1) and K (361.5 kg ha-1) was observed with the application of 100 % NP + 10 kg K (inorganic) + 20 kg K through gliricidia which increased by 16, 31.7 and 13.7% respectively over control. Similarly, the nutrient balance after six years of experiment was also higher with the application of 100 % NP + 10 kg K (inorganic) + 20 kg K through gliricidia being 25.4 kg ha-1 for available N, 2.15 kg ha-1 for available P and 39.6 kg ha-1 for available K. There was significant reduction in the bulk density of soil, being lowest (1.40 Mg m-3) in the treatment 100 % NP + 10 kg K (inorganic) + 20 kg K through gliricidia as compared to control. Significant improvement in the seed and stalk yield of cotton was recorded with the application of 100 % NP + 10 kg K (inorganic) + 20 kg K through gliricidia, with increment of 60, 18% and 64, 22% over control and 100% RDF, respectively.

A field experiment was conducted at Experimental Farm, Nagaland University, Medziphema campus, Nagaland during rabi season of 2019-2020 to study the response of broccoli (Brassica oleracea var. italica) to integrated nutrient management.The 12 treatments were evaluated in RBD with three replications. Results revealed that application of different levels of fertilizes and organic manures either alone or in combination significantly increased the growth, yield and quality of broccoli as compared to control. Application of full dose of RDF exhibited maximum plant height (50.3 cm), number of leaves (18.2), stem diameter (20.7 mm), plant spread (69.2 cm), ascorbic acid content (60.9 mg 100-1 g), protein content in head (1.58%) and yield (8.20 t ha-1). However, these parameters were found statistically at par with poultry manure 2.5 t ha-1 + ½ of RDF. There was a significant build up of organic carbon and available nutrients in post harvest soil with INM practices and maximum values of organic carbon (19.0 g kg-1), available P (20.9 kg ha-1) were recorded and available K (171.2 kg ha-1) with poultry manure 2.5 t ha-1 + ½ of RDF. While maximum value of available nitrogen (221.6 kg ha-1) in post harvest soil was recorded with full dose of RDF as inorganics. The highest net return (Rs. 1,96,145.51)along with benefit: cost ratio (2.16) were recorded in full dose of RDF followed by poultry manure 2.5 t ha-1 + ½ of RDF with net return of Rs.1,81220.35 and cost benefit ratio of 1.90.

A field experiment was conducted during February -August 2020 at Kollakudi village, Tiruvannamalai, Tamil Nadu, India to find the influences of organic manures on physiological and quality parameters of taro variety Sree Rashmi. The experiment was laid out in the randomized block design with nine treatments replicated thrice. Organic manures opted for the study include vermicompost, farm yard manure, phosphobacteria, neem oil cake applied in basal form, effective microorganisms, panchagavya, seaweed extract wassoil drenched on the day of sowing, 30th and 60thdays after sowing as per the treatment. The total cormel yield/ plant(618.94 g), total cormel yield / plot (24.13 kg), dry matter production (48.45 tha-1), total starch (9.88%), total sugar (1.89%), total folate (24.12 μg/100g) were found to be maximum with RDF+ vermicompost (5t ha-1) + sea weed extract (5ml/ litre) + phosphobacteria (2 kg ha-1) . Among the organic manures, combined application of sea weed extract, vermicompost and phosphobacteria proved to be superior to others in respect of quality and physiological parameters. The minimum values of all these characters were recorded under control.

Field experiments were carried out at the research farm of Regional Agricultural Research Station, Rajouri, SKUAST-Jammu during 2013 – 2016 rabi season under irrigated (IC) and rainfed conditions (RC) of inter-mediate zone of UT of Jammu & Kashmir in order to determine the high adaptive yielding with high quality bread wheat genotypes.The experiments were laid out in a randomized block design with 4 replications and six varieties of wheat. Genotypes were significantly different among themselves for all the phenological traits under irrigated and rainfed conditions. The pooled results of three years revealed that wheat genotypes VL 804 and HS 562 performed better in terms of growth, yield attributes and yield under irrigated condition compared to genotypes cultivated under rainfed condition. However, genotypes VL 907 and HS 507 ‘Improved’ found better in growth and yield than other genotypes under rainfed condition. The highest net returns of Rs. 76924 ha-1 and B:C ratio of 2.86 was recorded with in genotype VL 804 under irrigated condition and net returns of Rs. 39903 ha-1 and B:C ratio (2.78) in genotype VL 907 under rainfed condition.

Diagnosis and management of nutrient constraints are the two important pillars of sound citrus fertilizer program, although its history in India is as old as cultivation of citrus. Of the different diagnostic tools (leaf nutrient standards, soil thresholds of soil available nutrients, metalloenzyme activity, inflorescence analysis, juice nutrient standards, xylem sap analysis); leaf and soil-based nutrient standards have established their superiority over rest of the diagnostic methods. Optimum leaf nutrients standards developed for different commercial cultivars in Indiahave further warranted the necessity of identifying nutrient constraints through cultivar specific diagnostics in order to inflict precision diagnosis. Similar observations were envisaged through optimum soil fertility limits suggested for Indian citrus cultivars, primarily governed by prevailing soil fertility constraints. Multi-location nutrient specific field response studies lacked heavily on the point of uniformity in yield and quality improvements when replicated at other locations. Site-specific nutrient management studies demonstrated soil type-based fertilization, suggesting the fertilizers to be tailored as per canopy size within an orchard to derive rationality in fertilizer use within an orchard. Fertigation has further reduced the optimum fertilizer requirement by 30-40%, in addition to microbial consortium-based integrated nutrient management saving 30% cut from conventional RDF. Many other significant advances have taken place to improve the fertilizer-use-efficiency e.g. sensor-based variable rate application, fertigation using magnetized irrigation, open field hydroponics and dual purpose microbially loaded substrate (organic manure) enriched with limited inorganic fertilizers collectively known as INM a plausible alternative.

Field experiments were conducted on wheat cv. HD-2967 at farmer’s field during 2015-16 and 2016-17 to evaluate fertilizer management practices vis-a-vis farmer’s practice on wheat productivity and its profitability in Rajpura village of Aligarh, (U.P.) wherein three trials for each site were studied. Results indicated that, maximum average yield of wheat was 4.58 and 4.60 t ha-1 at site I and II, respectively under targeted yield approach for 5.5 tonne (TY5.5t) which were higher by 39.5% at site-I and 41.8% at site-II over farmer’s practice (FP). The application of nutrients under soil test based targeted yield approach; nearly 39-42% wheat yield could be increased over FP. Moreover, the higher net profit was recorded as Rs. 32,110 ha-1 and 28,400 ha-1 at site-I and II, respectively with targeted yield approach fertilizer management. The improvement in available nitrogen, phosphorus and potassium was noticed at both sites (I and II) under targeted yield based fertilizer management approach in post-harvest soil after two years of trials.
对小麦进行了田间试验。在2015-16年和2016-17年期间，在北方邦Aligarh的Rajpura村的农民田间进行了HD-2967试验，以评估肥料管理实践与农民小麦生产力及其盈利能力的关系，其中每个地点进行了三次试验研究。结果表明，在5.5吨目标产量方法下，I点和II点小麦的最高平均产量分别为4.58和4.60 t hm -1，比农民实践(FP)提高了39.5%和41.8%。基于土壤试验的养分施用定向产量法施用FP可使小麦增产近39 ~ 42%。此外，采用目标产量法施肥管理的i点和II点净利润分别为32110卢比和28400卢比。经过2年的试验，收获后土壤有效氮、磷、钾在1点和2点均有改善。
