A field study entitled ʻʻEvaluation of varieties at varied crop geometry for yield maximization in soybeanʼʼ was conducted at College farm, Agricultural College, Polasa, Jagtial, PJTSAU, during the kharif season of 2018. The experiment was laid out in split-plot design with three replications to evaluate the performance of promising varieties of soybean (V1- Basar, V2- JS 335, V3- KDS 756 and V4- MACS 1281) and to standardize the crop geometry for Soybean varieties (S1- 45 x 10 cm, S2- 30 x 10 cm, S3- 45 x 05 cm and S4- 35 x 05 cm) under rainfedsemi arid conditions of Telangana. The results obtained from the present experiment indicated that among the varieties the yield attributes and yield are numbers of pods plant-1, number of seeds pod-1, seed yield, stalk yield and harvest index (%) and monetary returns of KDS 756 variety was significantly higher as compared to other varieties followed by Basar, MACS 1281, respectively. Hundred seed weight was significant among varieties and was higher with variety KDS 756 followed by MACS 1281, JS 335 and Basar. JS 335 showed inferior performance regarding yield attributes yield and monetary returns. Among crop geometry 30 x 10 cm recorded higher yield characters and monetary returns followed by 45 x 05 cm, 30 x 05 cm and 45 x 10 cm, respectively.

Background: Crop yields in the semi-arid regions are low due to climatic and soil related constraints.Soybean as one of the most important legume crops grown worldwide, has a role to contribute nitrogen to improve nutrient poor soils in Africa. A study was conducted to examine the effects of Bradyrhizobium spp inoculations on the growth and yield of soybean varieties in a glasshouse.Method: The study was arranged in a randomized complete block factorial design, with factor A being two soybean varieties (Bimha and Status) while factor B was inoculation using four Bradyrhizobium strains and the uninoculated control. Results: Bradyrhizobium inoculation significantly (P less than 0.001)affected days to 50% flowering, days to emergence, nodule number, root dry weight and grain yield and yield traits. Parameters that were affected by both inoculant strain and variety included days to 50% flowering, days to emergence, number of pods per plant, pod weight and number of seeds per pod. The interaction effect of variety and Bradyrhizobium inoculant strain was observed only on number of pods per plants. Our study shows that soybean grows well when inoculated with Bradyrhizobium inoculants, in semi-arid conditions of Botswana.

SUMMARYIntercropping is a common practice in Africa, but the advantage compared to sole cropping depends on the crop plants and local agro-ecological conditions. The potential of intercropping maize (Zea mays) or sorghum (Sorghum bicolor) with watermelon (Citrullus lanatus) was tested in two on-farm trials in southern Mozambique under semi-arid conditions in an area with low and unpredictable rainfall. In the first experiment, plant density, yield and monetary value of sole and intercropping plots of maize with watermelon were determined in 17 farmers' fields in an area where all crops developed to maturity and harvest. There was a significant reduction in yield of both maize (28.8%) and watermelon (57.8%) in the intercrop compared with the sole crop yields. However, the mean land equivalent ratio of 1.13 for yield showed that intercropping had advantages as, on average, an area planted with sole crops would require 13% more land than an intercrop production to generate the same outcome. In the second experiment, carried out in another area with 16 farmers' fields, drought was more pronounced and only watermelon developed to maturity. Intercroppings with maize and sorghum resulted in 70% and 69% yield reduction, respectively. In conclusion, watermelon is a good companion crop for intercropping with cereals to mitigate the risk of total crop failure due to drought.

Aim: The existing research was undertaken to approximate the significance of interactive effects of varieties X fertilizer doses in mustard crop with saline water irrigation undersemi-arid conditions of Haryana. Methodology: The experiment comprised of mustard varieties viz. Kranti, Giriraj, CS-54 and CS-58 and three fertilizer doses viz. recommended fertilizer dose (RDF), i.e., 60:20:20, 125% of recommended fertilizer dose and 150% of recommended fertilizer dose under semi-arid conditions of Haryana. The study was carried out in a split plot design with varieties in main plots and fertilizer doses in subplots irrigated with 7 dSm-1 saline water. Results: Statistical analysis devised that both variety and fertilizer doses had significant effect on plant height, number of primary branches per plant, number of secondary branches per plant, number of siliquae per plant, number of seeds per siliqua, seed and straw yield. The interaction of variety and fertilizer dose had significant effect only on the seed yield. All the treatments and varieties were found economically positive but 150% fertilizer dose was proved to be more economical with highest net returns and B: C ratio in variety Giriraj, Kranti, CS-54 and CS- 58, respectively. Interpretation: Amongst four varieties CS-58 was better performer for all the growth and yield parameters with application of 150% recommended fertilizer dose under saline water irrigation.

Abstract Water is the most important limiting factor of cotton (Gossypium hirsutum L.) and wheat (Triticum aestivum L.) cropping systems in semi-arid conditions of Southern Punjab. A two-year field experiment (comprising of cotton-wheat cropping) was conducted in Vehari (Southern Punjab) to calibrate and validate a DSSAT model in the climatic conditions of 1 × CO2 concentration (conc.) (current). The model simulation during calibration was good with errors up to 4.7, 4.4, 10.1, 6.4 and −5.4% for days to anthesis, days to maturity, total dry matter, yield and HI, respectively for the cotton-wheat cropping system. During model validation, the error percentages were also under reasonable limits. So, the model was run under 2 × CO2 conc. (future) conditions and it showed a difference of −7.3 to 19.7% anthesis days, maturity days, total dry matter, grain yield, crop ET and WUEGY with respect to current CO2 concentration. Simulation by DSSAT showed that the cotton cultivar MNH-886 and wheat cultivar Lassani-2008 were better utilizers of limited water resources under changed climatic conditions in semi-arid conditions of Vehari, which was due to their better water use efficiency. Wheat and cotton cultivars with high water use efficiency would enable crop growth to maintain high crop yields under increased CO2 and its associated consequences in future.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to November 2016 to investigate the performance of separated tillers of hybrid rice variety Dhani Gold. The experiment comprised three times of tiller transplantation viz. 3, 4 and 5 week aged tiller seedlings and four levels of number of tiller seedlings transplanted hill-1 viz. 2, 3, 4 and 5 tiller seedlings hill-1 laid out in a split plot design with 3 replications. The highest plant height was obtained when 3-week aged tiller seedlings were transplanted at the rate of 3 tiller seedlings hill-1. The highest number of total tillers hill-1 and number of effective tillers hill-1 were found when 3-week aged tiller seedlings were transplanted with 5 tiller seedlings hill-1. The highest grains panicle-1 was obtained when 4-week aged tiller seedlings were transplanted with 5 tiller seedlings hill-1. The highest grain yield was found when 3-week aged tiller seedlings were transplanted with 5 tiller seedlings hill-1. The lowest grain yield was found when 5-week aged tiller seedlings were transplanted with 2 tiller seedlings hill-1 in hybrid rice variety Dhani Gold. Based on the findings of the present study it may be concluded that 3-week old tiller seedlings of Dhani Gold should be transplanted at the rate of 4 or 5 tiller seedlings hill-1 for higher yield. Thus present study confirms the potentiality of growing hybrid rice from separated tillers in case of unavailability of seedlings or to minimize the seed cost of high value hybrid rice seeds.
