Three-year (2014-2016) field experiment was conducted for evaluation of maize (Zea mays L.) based intercropping system for productivity, profitability, energy budgeting and soil health in Eastern Himalayan region. The treatments consisted of four sole crop viz. maize, soybean, groundnut, cowpea and six intercropping treatments viz. maize + groundnut (1:1), maize + soybean (1:1), maize + cowpea (1:1) and strip cropping of maize + groundnut (4:4), maize + soybean (4:4), maize + cowpea (4:4). The highest maize equivalent yield (10.2 t ha-1) was recorded in maize + groundnut cropping system (1:1) followed by maize + soybean (1:1) with 8.9 t ha-1. The highest SNBC (soil microbial biomass carbon) (66.2 mg g-1) and organic carbon (1.3%) were recorded with the cultivation of cowpea as a sole or intercrop. Strip cropping system, maize + cowpea (4:4) recorded the highest soil available N, P2O5 and K2O kg ha-1, highest energy efficiency (12.53) and energy productivity 955.01 g MJ-1

Different Levels

A field experiment was conducted to study the effect of SafeRock Minerals (SRM) application on soil microbiological parameters in rice-wheat cropping system. The experiments consisted of two methods of rice and wheat establishment and six different levels of crop nutrition including SRM with mineral fertilizers and organic manure (FYM). The rice was grown in kharif (June to October) season through aerobic direct seeded condition and flooded transplanted system. During rabi (October to April) season wheat was cultivated by two establishment methods viz. system of wheat intensification (SWI) and conventional wheat. The high yielding varieties of Basmati rice (Pusa Basmati 1509) and wheat (HD 2967) were used in the experiment. The results revealed that the soils of rice and wheat crops showed significant improvement in available N, P and K and soil microbial parameters (enzymatic activities and microbial biomass carbon) due to the integrated application of 250 kg/ha SRM + 100% recommended dose of fertilizer (RDF) and 250 kg/ha SRM + 50% RDF (chemical) + 25% RDF (organic) and 250 kg/ha SRM + 50% organic-FYM (10.0 t/ha) over the sole SRM application under both the methods of stand establishment of rice as well as wheat.

The Impact

At the SHUATS Department of Soil Science and Agricultural Chemistry Research Farm, an experiment was conducted with the goal of determining the impact of application of macro and micronutrients, on soil health nutrients concentration and uptake by maize (Zea mays L). The experiment was put up based on this over a two-year period, beginning with the 2017 and 2018 cropping periods. Crbd was used as the experimental technique and it was replicated thrice with the following treatments combinations, NPK @ 50 and 100kgha -1, while for the micronutrients (Boron, Zinc and Copper) three levels of combination were used 0.3, 6 and 9kgha-1. The research project's findings showed all the determinants of soil health like soil reaction organic matter among others are at levels suitable for nutrients actions and plant growth, while plant parameters like maize cob diameter, dry matter, and nutrients concentrations in maize tissues have greatly improved. NPK @100kgha-1, Copper, Zinc, and Boron @ 9kgha-1 were the best treatment combinations with the best results. The above combinations of treatments will be suitable for the soils of that location based on the results of these studies.

RESUMO – O Leste Maranhense corresponde à mais nova fronteira agrícola do Brasil. Entretanto, fatores limitantesda produtividade, como a escolha correta da variedade e o sistema de cultivo mais adequado para as condições locais,ainda são desconhecidos. Objetivou-se estudar o desempenho produtivo de 17 genótipos de milho, sob três sistemasde cultivo para a região. Foram realizados dois experimentos, um na cidade de Chapadinha e outro na cidade de Brejo,sendo avaliados 17 genótipos ao todo. Os ensaios foram dispostos no delineamento em blocos casualisados com quatrorepetições em esquema fatorial 3x10 [10 cultivares e três sistemas de cultivo (plantio com cobertura de palha decarnaúba; plantio sem cobertura; plantio intercalado com feijão caupi)]. O sistema de cultivo com palha de carnaúba,independentemente do genótipo de milho e do local de avaliação, proporcionou os maiores rendimentos de grãos.Em Chapadinha, os genótipos mais produtivos foram as variedades de polinização aberta Caiano e Al-Bandeirante,o híbrido duplo AGN 1051, os híbridos triplos 2B 433, BRS 3060 e CMS 3E482 e o híbrido simples P 3646 H. ParaBrejo, os melhores resultados foram obtidos pelos híbridos duplos 2B 707 HX e AGN 1051 e pelos híbridos simples2B 604 HX, 30 F35 H e P 3646 H.Palavras-chave: Zea mays L., Palhada, Rendimento de grãos.PRODUCTIVE PERFORMANCE OF MAIZE CULTIVARS IN THREE FARMING SYSTEMS IN EAST MARANHÃO STATEABSTRACT - East Maranhão State is the newest agricultural frontier in Brazil. However, productivity limiting factorssuch as the correct choice of variety and the cropping system more suitable to the local conditions are still unknown.The objective of this study was to evaluate the productive performance of 17 maize genotypes under three cultivationsystems for the region. Two experiments were carried out, one in the city of Chapadinha and another in the city ofBrejo, evaluating 17 genotypes. The trials were arranged in a randomized block design with 4 replications in a 3x10factorial scheme [10 cultivars and 3 cultivation systems (planting with cover of carnaúba straw, plantation withoutcover, intercropping with cowpea). The use of carnaúba straw provided the highest grain yields, regardless the maizegenotype and the evaluation site,. In Chapadinha the most productive genotypes were the open-pollinated varietiesCaiano and Al-Bandeirante, the double hybrid AGN 1051, the triple hybrids 2B 433, BRS 3060 and CMS 3E482 andthe simple hybrid P 3646 H. For Brejo the best results were obtained by the double hybrids 2B 707 HX and AGN 1051and by the simple hybrids 2B 604 HX, 30 F35 H and P 3646 H.Keywords: Zea mays L., Straw, Grain Yield.
