A field experiment was conducted in the central farm, Regional Research and Technology Transfer Station, Coastal Zone OUAT, Bhubaneswar during kharif 2020 using cv-Lalat variety of Rice. The experiment was laid out in randomized block design (RBD) with ten treatments and three replications. In this experiment BOF (Basic Oxygen Furnace) slag was used as a source of silica for application to rice crop. 200, 300 and 400 kg SiO2/ha was applied in combination with 50% STD and 75% STD in order to assess the efficacy of Silica with reduction in fertilizer dose by 50% and 25%. It was shown in case of grain yield, straw yield, and harvest index, 100% STD (T4) registered maximum (36.9q/ha) grain yield which was 29.4% more than that of control. Of course, grain yield in case of T9i.e., 75% STD+300kg SiO2/ha was at par 36.2q/ha indicated efficacy of silica application by reducing fertilizer dose. Harvest index was not significantly affected by Si treatments. However, maximum HI (0.478) was observed in T9. Available N, P, K and S status in post-harvest soil was increased significantly due to application of silica along with fertilizer over control indicated better availability of nutrients which plays a vital role in increasing production and productivity of rice. The content and uptake of N, P, K and Si was significantly increased over control due to application of silica with fertilizer. Though 100% STD (T4) was found to be very effective as compared to other treatments but 75% STD+300kgSiO2/ha was also equally effective so far as yield, yield attributing characters, available nutrient status, N, P, K and Si content and uptake along with Relative Agronomic Efficiency (RAE), Agronomic Efficiency (AE), Apparent Recovery (%) AR and Production Efficiency (PE) are concerned.

As maiores produtividades de proteína bruta e o menor tempo para cozimento foram proporcionadas pelos FN 00+45+45, 45+00+45, 90+00+00, 00+90+00 e 00+00+90.Palavras-chave: Phaseolus vulgaris; parcelamento do N; eficiência agronômica; tecnologia dos grãos. NITROGEN TOPDRESSING AT DIFFERENT PHENOLOGICAL STAGES ON COMMON BEAN CHANGES GRAIN YIELD AND QUALITY ABSTRACT: The need to know the nitrogen uptake (N) by common bean is important to understand the productive and qualitative performance of this crop. The objective of this study was to evaluate the influence of nitrogen topdressing as a function of different phenological stages on the morphometric and productive performance, and on the technological characteristics of the bean grains grown under conventional soil preparation. A randomized block design with four replications was used. The treatments were constituted by twelve topdressing N supply combinations (NS) (total dose = 90 kg ha-1 N) applied in the phenological stages V3, V4 and R5 (V3+V4+R5) of irrigated winter bean: 00+00+00; 30+30 +30; 30+60+00; 30+00+60; 60 + 30 + 00; 00+60+30; 45+45+00; 00+45+45; 45+00+45; 90+00+00; 00+90+00; and 00+00+90. The source of N used was conventional urea. NS 30 + 00 + 60, 00 + 45 + 45 and 45 + 00 + 45 increase grain yield and agronomic efficiency in relation to the absence of N and single dose application at V4 phenological stage of common bean. The highest crude protein yields and the shortest cooking time were provided by FN 00+45+45, 45+00+45, 90+00+00, 00+90+00 and 00+00+90.Keywords: Phaseolus vulgaris; N splitting; agronomic efficiency; grains technology.

The Relationship

In order to evaluate the relationship between yield and some relevant traits and estimation of the most effective traits on grain yield, a split-plot experiment based on completely randomized block design with four replications was carried out in 2006-2007 in the research field of Islamic Azad University of Karaj. The irrigation schemes scheduled as main plots included the following: (T1) 40% moisture depletion throughout the growing season (control); (T2) 60% moisture depletion throughout the growing season; (T3) 80% moisture depletion throughout the growing season; (T4) no irrigation during the stem elongation stage and continuing with adequate irrigation to the end of the growing season; (T5) no irrigation from the stem elongation stage to the end of the growing season; (T6) no irrigation at flowering and continuing with adequate irrigation to the end of the growing season; (T7) no irrigation from flowering to the end of the growing season; and (T8) no irrigation from the milk stage to the end of the growing season; and 2 wheat cultivars [Marvdasht (V1), Chamran (V2)] as sub-plots. According to the results of simple correlation, the grain yield exhibited the most positive correlation with biomass (0.877), number of infertile spikelets (0.876) and harvest index (0.855). The results of step-wise regression showed that, in the absence of drought stress, biomass and harvest index had respectively the most important effects on the grain yield but both exhibited different results under drought stress. Path analysis results showed that the most important effect on the grain yield in the total tested treatments was related to the biomass, justifying a total of 87% of grain yield variations, 72% of which is the direct effect of this trait on grain yield.

Aims: Screening of pearl millet genotypes lines for high temperature and drought tolerance. Study Design:  Randomized Block Design (RBD) with three replications. Place and Duration of Study: ICAR-AICRP on Pearl Millet, Mandor during summer 2017-18. Methodology: Fifteen genotypes (J-2290, J-2340, J-2479, J-2500, J-2503, J-2507, J-2517, J-2534, JMSB-9904, JMSB-101, JMSB-20064, JMSB-20102, JMSB-20071, JMSB-20082 and JMSB-20091) of pearl millet received from Main Pearl millet Research Station, Junagadh Agricultural University, Jamnagar were evaluated during  summer season of 2017-18 at research Farm of ACIRP on pearl millet, Mandor, Agricultural University, Jodhpur under terminal moisture stress  and irrigated  conditions in two sets of randomized block design with three replications. Grain yield, stover yield, Relative Water Content (RWC), harvest index, threshing percentage and chlorophyll content were recorded. Results: The suitability of the genotypes was judged in terms of grain yield, stover yield, RWC, harvest index, threshing percentage and chlorophyll content. The results showed that due to the terminal stress, the mean performance of all yield attributing characters including grain yield and chlorophyll, RWC and seed setting was reduced. The inbreds J-2479, J-2503 and J-2507 were high yielders due to high seed setting percentage under terminal stress conditions. Conclusion: The lines viz., J-2479, J-2503 and J-2507 can be used for further breeding programme to develop varieties suitable under high temperature and low moisture conditions.

ABSTRACT This study evaluated the response of carpet grass to pig slurry fertilization in order to estimate the agronomic efficiency and the plant-available nitrogen (N) of such manure. A field test was conducted during two years, following a randomized block design with six replicates of the treatments: 0, 100, 200, 300, 400 and 500 kg N ha-1 year-1, which resulted in 0, 60, 120, 180, 240 and 300 m3 ha-1 (2008/09), and 0, 42, 84, 126, 168 and 210 m3 ha-1 (2009/10), according to the N content of the pig slurry used in each year. These treatments were compared with ammonium nitrate (200 kg N ha-1 year-1), in order to estimate the plant-available nitrogen of the manure for the pasture. Pig slurry doses increased linearly the dry matter yield. In 2008/2009, it was increased from 2,600 (0 kg N ha-1) to 7,718 kg ha-1 (500 kg N ha-1), while in 2009-2010 it ranged from 4,310 (0 kg N ha-1) to 12,321 kg ha-1 (500 kg N ha-1). The average agronomic efficiency of the manurewas 15 kg DM kg-1 N and it was lower than that found with ammonium nitrate (27 kg DM kg-1 N).The estimated plant-available N of the pig slurry was similar between the growing years. The N fraction of this manure available to the pasture was 0.64 (2008-09) and 0.60 (2009-10).

Tidal swampland is potential but negligible land characterized by poor soil fertility. The study aimed to determine the effect of fertilization packages on the growth and yield of Inpara 2 rice in the tidal field. This research was conducted on the tidal field of Mon Mata Village, Krueng Sabee Sub District, Aceh Jaya, from July to November 2018. The study was designed in a Randomized Block Design three treatments, and three plot replications of 10 m x 10 m. The treatments comprised of three fertilization packages, namely: Farmer’s package A (Urea 100 kg ha–1 + SP 36 50 kg ha–1); Package soil nutrient status B (Urea 200 kg ha–1 + SP36 100 kg ha–1 + KCl 50 kg ha–1), and Recommended package C (Urea 200 kg ha–1 + SP36 100 kg ha–1 + KCl 100 kg ha–1 + 1000 kg dolomite ha–1). The experiment showed that all three fertilization packages significantly impacted plant height, panicle length, number of panicles per hill, grain per panicle, and grain yield. The recommended fertilization package C gave the highest yield (5.20 t ha–1), followed by Package B (4.78 t ha–1) and Package A (3.55 t ha–1). The research suggests that Inpara 2 rice and fertilizers, according to the recommendations, are needed to increase rice productivity in tidal fields.

Sixteen genotypes of rice (including one check) were evaluated on 18 quantitative traits during sali (August), 2018 in a randomized block design with three replications at Instruction cum Research Farm, Department of Plant Breeding and Genetics, Assam Agricultural University, Jorhat to study the nature and magnitude of variability, heritability and genetic advance under delayed sown condition. The analysis of variance for 18 quantitative traits revealed the presence of significant differences for grain yield and its component characters. The highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was observed for chaffs per panicle followed by grains per panicle, spikelet sterility (%), spikelets per panicle, grain yield (kg/ha). A high heritability coupled with high genetic advance was observed for plant height (cm), spikelets per panicle, spikelet sterility (%), chaffs per panicle, grains per panicle, grain yield (g/hill), grain yield (kg/ha), biological yield (kg/ha), straw weight (kg/ha) and harvest index (%) indicating that selection might be effective for improvement of these characters under delayed sown condition with low input. From the findings of this investigation, one genotype viz., Gandhari emerged as the outstanding genotype which yielded 4170 kg/ha and could be directly used for cultivation in delayed sown situation with low inputs. Some other promising genotypes that yielded higher than the check Manoharsali under delayed sown condition were JR 29, JR 16, Basundhara and JR 60 and could be utilized as potential parental material in the hybridization programmes designed to develop suitable rice varieties for delayed sown situation.
