SUMMARYThe north eastern region (NER) of India receives a high amount of rainfall (2450 mm) both in terms of intensity and frequency. Most of the precipitation goes waste because of improper conservation measures and inadequate rainwater harvesting. Growing a second crop during winter (rabi) season on hill slopes and uplands without moisture conservation measure is almost impossible. A simple and very low-cost technique of in situ soil moisture conservation in maize (Zea mays L.)–toria (Brassica campestris L.) system has been developed using residue of preceding rainy season maize crop and mulching with locally available weed biomass Ambrosia artemisiifolia. Six residue mulching combinations tested were viz. control, Maize stalk cover (MSC), MSC + Ambrosia sp. 5 t/ha, MSC + Ambrosia sp. 10 t/ha, MSC + farmyard manure (FYM) 10 t/ha and MSC + Ambrosia sp. 5 t/ha + poultry manure 5 t/ha under zero tillage (ZT) and conventional tillage (CT) systems. Results showed that in situ residue retention of preceding maize crop along with green biomass of Ambrosia sp., applied before sowing of toria, maintained optimum soil moisture for good growth and higher yield of toria. The soil moisture content was consistently higher under residue mulched plots than that under control. All the residue mulching measures recorded higher crop yield for maize and toria than those observed under residue removal (control). The productivity of toria was enhanced by about 99%, only due to retention of MSC as mulch. Mulching with MSC + Ambrosia sp. 5 t/ha + poultry manure 5 t/ha recorded the highest seed yield of toria (four-year average: 641 kg/ha), which was 228% and 64% higher than no mulching (control) and MSC alone. MSC + FYM 10 t/ha (568.3 t/ha) and MSC + Ambrosia sp. 10 t/ha (517.4 t/ha) were found equally effective and produced significantly higher toria yield than that of control. MSC + Ambrosia mulch 10 t/ha gave the highest net returns and B:C ratio of the maize–toria system. The overall B:C ratios were better under ZT than CT. Thus, the study indicated that the integrated management of crop residues and weed biomass (Ambrosia sp.) under ZT created favourable soil moisture to support double cropping with high yield in hill eco-system of northeastern Indian Himalayas.

ABSTRACTThis research was conducted in the Analitic laboratory of Palangka Raya Univercity and in the screenhouse of Agriculture Cultivation Department, Palangka Raya Univercity. The purpose of thisexperiment was to determine the effect of dolomit and chicken manure to some soil chemicalproperties of acid sulfate soil and growth of Maize Crop (Zea mays L.). The research was arranged inComplete Ramdomized Design with two factors and three replications. The first factors were level ofdolomit with three levels namely 0 ; 1,5 ; 3,0 times exchangeable alumunium. The second factors werelevel of chicken manure with three levels namely 0, 6 and 12 t ha-1. The results showed that theinteraction between dolomit and chicken manure significantly affected increasing the soil pH anddecreasing exchangeable alumunium. The combination level of dolomit in level 1,5 timesexchangeable alumunium with application of 6 ton.ha-1 chicken manure will be optimum increasingthe soil pH and decreasing exchangeable alumunium. The application a single factor of dolomit notsignificantly affected P-availabilityand growth of Zea mays (plant height, number of leaf and area leafindex) in age 2, 3, 4, 5, 6 weeks after planting. The application of chicken manure only significantlyaffected increasing P- availabilityand growth of Zea mays (plant height, number of leaf and area leafindex) in age 2, 3, 4, 5, 6 weeks after planting. Optimum dosage of chicken manure was 6 t ha-1.Keywords: sulfate soil, dolomite, soil chemical, chicken manures.

 ABSTRACT – In Brazil, the rainfed maize crop may undergo yield breaks due to uncertainties in the rainfall distribution. Irrigation can be a management alternative that, however, requires evaluation and planning to be helpful. The objective of this work was to analyze the simulated yield data of irrigated maize in counties of Minas Gerais state, Brazil. The CSM-CERES-Maize model was used to simulated weekly sowings of maize considering optimum agronomic conditions. A sprinkler irrigation scheme with 80% efficiency was used with automatic applications when the crop withdrew 50% of the soil available water. The harvest was scheduled to happen automatically when the crop had reached physiological maturity. The results were statistically analyzed for each county, based on goodness of fit test, ANOVA, Tukey’s test and risk analysis (stochastic dominance). The most promising sowing period was from January 16 to March 27 for all locations, except for Janaúba, for which the best sowing window was from November 14 to January 2. The treatments of highest average simulated maize yield stochastically dominated the other treatments evaluated. The CSM-CERES-Maize model proved to be a useful tool to help making decision in irrigated maize crop systems.Keywords: Zea mays L., CSM-CERES-Maize, DSSAT, risk analysis. MODELAGEM APLICADA A DATAS DE SEMEADURA DE MILHO IRRIGADO  RESUMO – No Brasil, a produção de milho de sequeiro pode sofrer quebras de rendimento devido a irregularidades na distribuição de chuvas. A irrigação pode ser uma alternativa de manejo que, todavia, requer avaliação e planejamento para ser benéfica. O objetivo deste trabalho foi analisar a produtividade simulada de milho irrigado em municípios do estado de Minas Gerais, Brasil. O modelo CSM-CERES-Maize foi utilizado para simular semeaduras semanais de milho, assumindo condições agronômicas ótimas. Considerou-se um esquema de irrigação por aspersão com 80% de eficiência, com aplicações automáticas quando a planta extraísse 50% da água disponível do solo. A colheita foi programada para acontecer automaticamente quando a cultura atingisse a maturidade fisiológica. Os resultados foram estatisticamente analisados para cada município, com base em teste de aderência, ANOVA, teste de Tukey e análise de risco (dominância estocástica). O período de semeadura mais promissor foi de 16 de janeiro a 27 de março, para todos os locais, exceto Janaúba, em que a melhor janela de semeadura foi de 14 de novembro a 2 de janeiro. Os tratamentos de maior rendimento médio simulado de milho dominaram estocasticamente os demais tratamentos avaliados. O modelo CSM-CERES-Maize demonstrou ser uma ferramenta útil para auxiliar na tomada de decisão em sistemas de produção de milho irrigado.Palavras-chave: Zea mays L., CSM-CERES-Maize, DSSAT, análise de risco.

An Implemented pot experiment  has been conducted in Al-Qadisiyah city - sadder AL- Yusufiya - District 9 in Spring planting season 2016 to study the effect of the overlap between the mineral , organic and bio fertilization in some  growth indicators to maize crop (Zea mays) in Silt Loam texture soils with factorial experiement according to completely randomize  design (Complete random design) and with  three replicates. The expenneit has been done by adding  mineral fertilizers (240 kg N. ha-1 and 80 kg P. ha-1 and 120 kg K. ha-1) three levels (0, 50% and 100%) respectively; and two levels of organic fertilizer (0 and 10 Mg. ha-1) respectively; and two levels of bio-fertilizer (0 and 2 ml. L-1) respectively to the irrigation water. The addition of mineral , organic and bio fertilizers has a significant effecct on the dry matter amount  and the treatment (M2O1B1) is given the highest average of  the dry matter,which reaches to 57.27 g.pot-1 as compared with the control treatment (M0O0B0), reacches to 20.46 g.pot-1 and the increasing percentage reach to 179.91%. There are no significant differences between (M1O1B1) and (M2O1B1). The triple overlap among the metal and organic fertilizers and bio has a significant effect on increasing the percentages of N, P and K in maize plants%, the treatment (M2O1B1) has achieved the highest average of 3.67% N and 0.49% P and 2.19% K respectively, compared with the treatment control (M0O0B0) 2.21% N and 0.23% P and 1.33% K sequentially with  increasing which presentage reached  to  66.06 N% and 113.04 P% and 64.66 K%. There are no significant differences between the treatments (M1O1B1) and (M2O1B1).
