A field experiment was carried out at Agricultural Research Station, Vizianagaram, during Kharif, 2016 under rainfed conditions to know the fertilizer responsiveness of promising finger millet varieties to graded doses of NPK fertilizers. Twenty treatment combinations were tested in split- plot design with three replications. Experimental results revealed that with 125% RDF grain yield increase was 10%, 27% and 48% higher than 100% RDF, 75% RDF and 50% RDF respectively. Among the finger millet genotypes, grain yield of VL-379(2037 kg/ha) and VL-352(1989 kg/ha) was significantly high and was at par with national check variety VR-708(1959 kg/ha). Both the test varieties (VL-379 and VL-352) were far superior to local check variety in terms of growth and yield characteristics. Higher net monetary returns and B:C ratio were obtained with VL-379, followed by VR-708 and VL-352 at 125% RDF.

Background: Blackgram is an important crop among kharif pulses and is usually grown on marginal and sub-marginal lands without proper weed management under rainfed situation. Broad bed furrows had greater influence on plant growth over farmers practice. Weed management through mechanical or manual is normally tedious, labour consuming and costlier. Keeping this in view, the present study was envisaged to investigate integrated effect of land configuration and weed management regimes on productivity of urdbean. Methods: A field experiment was carried out during kharif seasons of 2016 and 2017 at Regional Agricultural Research Station, Lam, Guntur on effect of land configuration and weed management on performance of urdbean (Vigna mungo L.Hepper). The treatments included two land configurations i.e., flat bed and broad bed furrow method allotted as horizontal plots and four weed management practices i.e., weedy check, pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE, imazethapyr 10% SL @ 55 g ha-1 at 15-20 DAS and pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS allotted as vertical plots replicated four times in a strip plot design. The comparison of treatment means was made by critical difference (CD) at P less than 0.05 by using standard statistical procedures. Result: Based on the results, it can be concluded broad bed method of land configuration proved its superiority over flat bed method by producing 12.8 per cent higher grain yield besides empowering growth and yield attributes. Among the weed management practices, the highest grain yield (1280 kg ha-1) recorded with pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS along with maximum monetary returns and B:C can be recommended for urdbean.

An experiment was conducted to assess the yield and yield components of QPM genotypes to plant population under irrigated conditions in a semi arid ecology of Northern Nigeria. Field trials were conducted at the Irrigation Research Station, Institute for Agricultural Research, Kadawa (11° 39'N, 08° 20'E) and 500 m above sea level) during dry seasons 2007, 2008 and 2009 to study the effect of (Zea mays L.) genotypes (TZE-W Pop X 1368, EV-DT W99 STR and DMR-ESRW), four plant population (33333, 44444, 55555 and 66666 plants ha-1) and three irrigation scheduling (40, 60 and 80 centibars soil moisture tension) on the growth and yield of quality protein maize. A split plot design was used with combinations of genotypes and irrigation regimes assigned to the main plot and plant population assigned to the sub-plot. The treatments were replicated three times. The study revealed that genotype EV-DT W99 STR had significantly higher weight of ears per plant, cob length, cob diameter, number of rows per cob, 100 grain weight, grain yield, shelling percentage and harvest index than the other two genotypes used in the trial. Irrigating at 40 and 60 centibars significantly increased weight of ears per plant, while delayed irrigation significantly depressed total dry matter production. Based on the results obtained in this study, it can be concluded that the use of genotype EV-DT W99 STR, at 60 centibars irrigation scheduling and population of 55,555 plants ha-1 had resulted in good agro-physiological characters of QPM at Kadawa.

The growth and yield characters of chickpea varieties suitable for mechanical harvesting were evaluated through field experiment conducted for three consecutive years (2016__17 to 2018__19) during rabi season on vertisols under rainfed conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh. The investigation was carried out in split plot design with three replications. Two plant geometries (30.0 × 10.0 cm and 22.5 × 10.0 cm) were assigned to main plots and six chickpea varieties (viz., GBM 2, Dheera, CSJ 515, HC 5, Phule G 08108 and BRC 1) were assigned to sub plots. Pooled analysis of experimental results indicated that significantly higher number of branches per plant (8.7) and number of pods per plant (31.1) and test weight (24.3 g) were observed under 30.0 × 10.0 cm when compared to 22.5 × 10.0 cm. Higher plant height (44.8 cm), height of lowest pod bearing branch (30.0 cm), lower days to 50 % flowering (42.1 days) and higher test weight (31.2 g) were observed in Dheera. Higher number of branches per plant (9.2) and number of pods per plant (34.2) were observed in GBM 2. Higher seed yield was observed in Phule G 08108 (1708 kg ha-1) which is followed by GBM 2 (1675 kg ha-1) Dheera (1569 kg ha-1) and BRC 1 (1493 kg ha-1). Higher harvest index (56.4%) was also observed in Phule G 08108. Chickpea varieties GBM2, Dheera and BRC1 were best suitable for mechanical harvesting and higher seed yield due to their excellent morphology.

Background: Water scarcity is one of the major problems faced by farmers for crop production. Productivity and sustainability of a crop like wheat which is highly susceptible to water stress could be affected the most. Identifying and growing such varieties of wheat which could thrive under restricted irrigation could solve the problem. The current study aimed to evaluate the performance of certain new wheat genotypes under restricted irrigation.Methods: A field experiment was conducted in eastern sub-Himalayan plains during Rabi season, 2016-2017 to evaluate the performance of certain wheat genotypes under restricted irrigation. The experiment was laid out in a split plot design with three different levels of irrigation, viz., no irrigation, one irrigation at CRI stage, two irrigations at CRI and booting stage, randomly allotted in main plots; while six genotypes comprising HI 1612, HD 2888, C 306, K 8027, HD 3171 and K 1317 were randomly allocated in sub plots.Result: It was observed that with increase in number of irrigation, the overall biomass production increased irrespective of genotypes. The highest biomass (7.38 t ha-1) was achieved in plots where two irrigations were given. Higher leaf area with increased plant height and tiller number as well as higher values of major yield components viz., number of spikes m-2 and number of filled grain spike-1 were also achieved in plots receiving two irrigations. The twice irrigated plot also exhibited higher yields (3.02 t ha-1) as compared to once irrigated plot. With increase in number of irrigation the grain yield increased significantly. Among the genotypes, HI 1612 reflected the maximum grain yield (2.76 t ha-1) under restricted irrigation though there was no significant variation in grain yield achieved with the other 5 genotypes except HD 3171.

The Crop Simulation Model (CERES-wheat module) of the Decision Support System for Agrotechnolgy Transfer (DSSAT) was used in this study to simulate the effect of planting date (D) on growth, development and yield of three varieties of durum wheat (Triticum turgidum L subsp. durum). The studied varieties were Cham1 (V1), Deir Alla6 (V2) and Haurani (V3). Data were obtained from a field experiment conducted for this purpose on the growing season 2015/2016 at Mushagger Agricultural Research Station Southwest Amman (31° 46' 24.7'' N, 35° 47' 47.3'' E, 800 m above sea level). First planting date (D1) was used for model calibration and the GenCalc software was applied to achieve acceptable genetic coefficient values. Calibration results showed an excellent estimation for days to anthesis, number of grains m-2, grain yield and days to physiological maturity with normalized root mean square error (nRMSE) ranged from 0 to 5.79%. Tops weight, harvest index, unit grain weight (except for V3) and number of tillers m-2 were poorly simulated. Validation of the CERES-Wheat model of the DSSAT using means of observed results of D2 and D3 showed excellent simulation (nRMSE < 10%) for anthesis and maturity dates for the three examined varieties. Good prediction (10 ≤ nRMSE < 20%) were attained for grain yield (for V2 and V3) and for grain nitrogen percent (except for V3 which was excellent). Fair predictions (20 ≤ nRMSE < 30%) were recorded for grain unit weight of (V1 and V2) and tops weight of V1. Conversely, grain unit weight was poorly simulated for V3. From these results, it can be concluded that the DSSAT model can be considered as an effective tool for predicting wheat growth and yield.

Varietal Improvement

The regional varietal experiments of wheat were composed by selecting promising genotypes from coordinated varietal trial. Both early and late sown experiments of wheat regional varietal trial (RVT) were seeded in Regional Agricultural Research Station, Tarahara, Sunsari, Nepal in 2014 and 2015. Late sown experiment was seeded after 15 days of early seeding experiment to identify suitable genotypes for delay seeding condition. Amongst the tested genotypes in RVT early of 2014 and 2015, the highest grain yield was produced by BL 3555 (3351 kg/ha) and BL 4018 (3309 kg/ha). Similarly BL 4012, BL 3978, BL 3264 and BL 4406 genotypes also recorded 12-18 percent higher grain yield than the yield of standard check variety, Aditya. All tested characters except spikes/m2 included in over year analysis of RVT early was found significantly different due to genotypes. Similarly out of the tested genotypes in RVT (late) of 2014 and 2015, NL 1177 (2933 kg/ha) and BL 3555 (2764 kg/ha) were found high yielding genotypes in combined analysis over year and grain yield of other tested genotypes was observed at par with check variety.  Days to heading, maturity, plant height and yrain yield of RVT (late sown) experiment were observed significantly different due to genotypes in over year analysis.Int J Appl Sci Biotechnol, Vol 4(4): 519-524
