A traditional scented rice (cv. Radhunipagal) was tested under varied spacing (20 cm × 20 cm, 20 cm × 15 cm, 15 cm × 15 cm and 20 cm × 10 cm) and seedling age (25, 35 and 45 days) during wet (kharif) season of 2018 at B.C.K.V., Nadia, West Bengal. Seedling age caused significant variation in life duration and summed GDD from 147.9 days and 2436°C day (25-day aged) to 162.0 days and 2753°C day (45-day aged), but with maturity in same meteorological week. Square planting (15 cm × 15 cm or 44 hills m-2) resulted in highest grain yield (2.52 t ha-1), which was 2.85, 11.01 and 4.56% greater over wider (20 cm × 15 cm and 20 cm × 20 cm) and closer spacings (20 cm × 10 cm). Radhunipagal rice raised with 25-days old seedlings recorded the highest grain yield (2.53 t ha-1) and maximum heat use efficiency (0.90 kg ha-1 °C day-1), and that yield was 0.12 and 0.22 t ha-1 greater over the crops planted with 35 and 45-days old seedlings during wet season. Spacing could not influence the cooking and processing quality (gelatinization temperature, kernel elongation ratio and aroma) except protein content of milled rice in the study. Radhunipagal paddy planted with 45-day aged seedlings recorded maximum protein content (6.36%) and alkali spreading value (score 3.27).

Irrigation Levels

The effect of irrigation regimes (irrigation at 1, 3 and 5 days interval) on four rice hybrids (6129 Gold, 6444 Gold, Tej Gold and DRH 775) was studied in split plot design during dry (boro) season of 2017 at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal. Mean cultivar days to 50% flowering and maturity of hybrid rice were 99.1 and 125.9 days, respectively; while total summed GDD, HTU and PTU for entire life cycle were 1656°C day, 10410°C hour and 20311°C hour, respectively. Irrigation at 1 day interval resulted in highest grain yield (5.92 t ha-1), heat use efficiency (3.62 kg ha-1 °C day-1) and head rice recovery (58.2%), but lowest (3.08 kg ha-1 mm-1) water use efficiency (WUE). Among four hybrids, 6129 Gold yielded highest (5.88 t ha-1) with maximum WUE (4.44 kg ha-1 mm-1) and high-intermediate gelatinization temperature (score 3.0), that yield was 0.31, 0.42 and 0.51 t ha-1 greater over Tej Gold, DRH 775 and 6444 Gold, respectively. Irrigation regime could influence a few grain quality parameters viz. brown rice (73.8-75.6%), head rice recovery (53.3-58.2%) and alkali spreading score (score 3.2-4.1) in the investigation. Irrigation at 3 days interval might be adopted due to better WUE (5.02 kg ha-1 mm-1) with moderate grain yield (5.80 t ha-1) during boro season in lower gangetic plains of West Bengal.

Effect On Yield

SUMMARYThe effect of seed protein content on grain yield has been studied in varieties of spring barley, oats and wheat grown under differing cultural conditions. Grain yield was affected by seed protein content in one experiment where very low yields were attained, but the effects were inconsistent. No effect was observed in two other experiments made in a glasshouse and the field. In a growth-room experiment, seed with high protein content produced more vigorous seedlings than low-protein seed; these differences were accentuated by increasing seedling age at very low nutrient levels, but decreased with seedling age at normal nutrient levels. It is concluded from the results that variations in seed protein content are unlikely to have a significant effect on yield under practical conditions.

Intraspecific mixtures may be a means of enhancing the genetic variability of modern crops while retaining the advantages of yield, quality, and stress tolerance of modern cultivars. Two- and three-way barley (Hordeum vulgare L.) mixtures of the cultivars Abee, Noble, Tukwa and Virden, were studied at Botha, Lacombe and Olds, Alberta, from 1992 to 1994. Treatments consisted of the four cultivars as monocrops and in 6 two-way and 3 three-way mixtures grown at a seeding rate of 250 seeds m−2. Tukwa as a monocrop had the highest rank and best stability for grain yield of all the treatments. Grain yields of the mixtures usually fell between the yields of the respective monocrops and were often better than the weighted mean yield of the monocrops indicating that many mixtures were more effective at using resources than the monocrops. Of the mixtures, Tukwa:Noble, Tukwa:Abee:Virden and Noble:Virden had the best rankings and stability for grain yield. Test weights, kernel weights, percent thins, lodging, disease incidence and protein content of the mixtures were intermediate to those of the monocrops. Mixtures containing the two-rowed cultivar Abee had higher test weight and protein content than mixtures composed of only six-rowed cultivars. Lodging and disease ratings were lower for the mixtures composed of only six-rowed cultivars than those with Abee. In these intraspecific barley mixtures, Virden was often the most competitive cultivar while Tukwa was the least. Competitive ability was not associated with yield potential, tillering, or row-type.

Irrigation scheduling at 0.8 IW/CPE ratios (I<sub>3</sub>) resulted in significantly the highest grain yield (1677 kg ha<sup>−1</sup>), protein content (20.85 %) and significantly higher stover yield (4858 kg ha<sup>−1</sup>) and gave highest net monetary returns of Rs.37591 ha<sup>−1</sup> with maximum B:C ratio of 2.34. Application of sulphur @ 40 kg S ha<sup>−1</sup> (S<sub>2</sub>) recorded significantly the highest grain (1630 kg ha<sup>−1</sup>) and stover (4819 kg ha<sup>−1</sup>) yields. In case of protein content and economics, application of sulphur @ 40 kg S ha<sup>−1</sup> recorded significantly the highest protein content (21.03 %) and the highest net monetary returns of Rs.35000 ha<sup>−1</sup> with maximum B:C ratio of 2.19. Interaction effect between irrigation scheduling and sulphur levels on grain yield was highly significant. Irrigation scheduled at 0.8 IW/CPE ratio with the application of 40 kg S ha<sup>−1</sup> recorded significantly higher grain yield (1929 kg ha<sup>−1</sup>) , however, it was at par with the irrigation scheduled at 0.8 IW/CPE ratio with 20 kg S ha<sup>−1</sup>.

Effect Of Age

The experiment was conducted at the Agronomy research field of Bangladesh Agricultural University, Mymensingh from July to December 2013 to find out the effect of seedling age and storage duration on growth and yield of wet season rice. The experiment comprised of four ages of seedling (25, 30, 35 and 40-d-old) and four storage durations (0, 1, 2 and 3-days) of uprooted seedlings. Rice var. BRRI dhan52 was used as a test variety. The experiment was laid out in a split-plot design with 3 replications placing seedling age in the main plot and storage duration in the sub- plot. The effect of age and storage -duration of seedling, and their interaction were significant on growth parameters (shoot height, root length, number of tillers hill-1, leaf area index and crop growth rate), grain yield and straw yield. The growth parameters and yield exhibited a trend of decrease with the increase in seedling age and storage duration. All the growth parameters and yield showed highest value in the younger seedlings of 25-d-old with 0-day storage duration of uprooted seedlings while the lowest in the older seedlings of 40-d-old with 3-days of storage duration. The var.BRRI dhan52 produced the highest LAI (8.23), CGR (7.33 mg day-1 hill-1) and biomass (26.87 g) at 60, 45 and 60 days after transplanting. Grain yield reduced by 13, 19 and 37% of 30, 35 and 40-d-old seedlings, respectively compared to 25-d-old seedlings. In case of seedling storage, grain yield reduced by 5, 14 and 31% of 1, 2 and 3-d storage, respectively compared to 0-d storage. For optimum growth and yield of wet season rice, 25-d-old seedlings may be stored up to 1-day after uprooting taking into account the possible delay in transporting seedlings to the flood affected area from the nearby districts.Bangladesh Agron.

Crop Performance

Drought is common under rainfed lowlands in Lao People’s Democratic Republic, and with the uncertain onset of rains during the wet season, delay in transplanting results in yield reduction. This study aims to explore ways to ameliorate the negative influence of delayed transplanting on rice crop. A field experiment was conducted for two wet seasons to investigate the effect of seedling age and seedling density on crop performance in terms of grain yield and water productivity. The experiment was laid out in a split–split plot design in four replicates, with seedling age as the main plot, seedling density as the subplot, and varieties as the sub-sub plot. In both years, there were significant seedling age and variety interactions on grain yield. Higher grain yields were observed with older seedlings having stronger tillering propensity. Seedling density did not affect grain yields in both years, but on grain yield components. Shorter duration variety received less supplemental irrigation than longer duration varieties. Late transplanting improved total water productivity but decreased irrigation water productivity due to harvesting delay. The total crop growth duration (from sowing to maturity) was prolonged with transplanting delay. However, the total stay of plants in the main field (from transplanting to maturity) was reduced by 3–5 d for every 10 d delay in transplanting. The results indicated that a good selection of varieties and increasing seedling density improve crop performance and water productivity with delayed transplanting.

Annual Application

A study was initiated in the fall of 1996 in the Black soil zone in east-central Saskatchewan (parkland region) to examine the soil and crop response to application of liquid swine manure at different rates, frequencies and methods of application. Low, medium and high rates of liquid swine manure (equivalent to approximately 100, 200 and 400 kg total N ha-1, respectively) were applied annually and in reduced frequency applications using injection and broadcast/incorporated placement over a 4-yr period. Crops grown during this period were Argentine canola (Brassica napus L.) in 1997, hard red spring wheat (Triticum aestivum L.) in 1998, hulless barley (Hordeum vulgare L.) in 1999, and Argentine canola in 2000. Under an annual application regime, a significant elevation of pre-seeding available N in the 0–60 cm soil depth and increased grain yield and protein content with increasing application rates of liquid swine manure were observed. Under a reduced frequency application regime, elevation of pre-seeding available N, grain yield and protein content observed in the year of application declined in the second year, and were significantly diminished by the third year. Cumulative N use efficiency (NUE) was highest (50–60%) for low annual application and lowest (10–30%) for high annual application rates that were injected. Generally, injection of liquid swine manure into the soil resulted in better enhancement of pre-seeding available N, higher grain yield and protein content, and better NUE than broadcasting and incorporation. Type of opener used to inject swine manure had no significant effect on either crop response or available N. This study showed that in the Black soil zone of the parkland region of Saskatchewan, annual application of low to medium rates (100 to 200 kg total N ha-1) of liquid swine manure are sufficient for high grain yield and grain protein, without leaving excess nitrates in the soil. In contrast, annual application of high rates (400 kg total N ha-1) of liquid swine manure has no agronomic advantage over the lower rates, but may result in higher residual nitrates in the soil, increasing potential for environmental pollution.

The effects of temperature, nitrogen fertility (N), and moisture stress on the yield components, protein content and moisture use efficiency of Manitou wheat (Triticum aestivum L.) were determined under simulated irrigation in a 2 × 3 × 5 factorial experiment. Grain yield was directly related to and mainly influenced by N. Yield was directly related to the number of spikes (r = 0.71**), and the number of seeds/spike (r = 0.65**), and inversely related to average seed weight (r = −0.41**). Seed weight was also inversely related to the number of spikes and number of seeds per spike. At maturity, the number of spikes was directly and mainly affected by N. The number of spikelets per spike, seed set of primary and secondary florets, and seed weight were inversely related to, and mainly a function of, temperature. At high temperature and low NO3-N, low moisture stress was detrimental to several yield components where these conditions existed during a period critical to the development of the component. These poor responses were alleviated by high moisture stress or high rate of NO3-N fertilizer or both. Grain protein was mainly influenced by temperature to which it was directly related. Protein was increased by N at day/night temperatures of T22/12 °C, but was unaffected by N at T27/12 °C; it was also increased by high moisture stress applied between last leaf visible and anthesis. Grain protein was inversely related to grain yield at any given level of N. Covariance was used to isolate the true effect (i.e., corrected for yield effects) of the treatment variables on protein. In this experiment, N influenced protein only via its effect on grain yield. Moisture use efficiency for grain production was improved by all factors that increased grain yield (e.g., increased N, low temperature, or high moisture stress between tillering and last leaf visible). Efficiency was deleteriously affected by moisture stress between last leaf visible and anthesis.
