Rice transplanting and sowing time sometimes get delayed due to lack of assured irrigation or surplus of rainfall. Moreover, no specific varieties have been specifically developed for this purpose. An experiment was conducted to study the effect of sowing dates and varieties on growth and yield of direct seeded rice during rainy season in 2010. The experiment was laid out in split plot design with four sowing dates and three varieties in sub plot. Sowing date on June 13th contributed to higher grain yield; higher gross return; net return and higher B:C ratio per hectare. Similarly, the variety Hardinath-1 excelled better in all these parameters with early maturity. The interaction effect of Hardinath-1 with June 13 sowing took lower days for maturity; produced higher number of effective tillers (386.3); heat use efficiency (2.14); straw yield (7.43 t ha-1); and relatively higher grain yield (4.22 t ha-1); gross return (Rs.108.55 thousand); net return (Rs. 51.22 thousands) and B:C ratio (1.89). Therefore, variety Hardinath-1 with June 13 sowing is best suited to get higher yield, timely maturity and higher economic return in Chitwan conditions.

The experiment was conducted at the field laboratory of the Patuakhali Science and Technology University, Patuakhali, Bangladesh during the period from November, 2011 to March 2012 under the tidal Floodplain region to find out optimum sowing time for the selected three cultivars (BARI Sharisha-15, BINA Sharisha-5 and BARI Sharisha-9). There were four sowing dates viz. 30 November, 15 December, 30 December and 15 January. Significant variations due to different sowing dates were observed in plant height, total dry matter, leaf area index, number of siliqua plant-1, seeds silique-1, 1000-grain weight, grain yield and HI. Results showed that the highest grain yield (1.73 t ha-1) was obtained from the first sowing (30 November) with BINA Sharisha-5 and it was significantly different from the yields of all other combination.J.

A field experiment on different maize cultivars planted at different sowing dates were accomplished at Kawasoti-5, Nawalparasi during spring season of 2013 to find suitable sowing date and maize cultivar for the location. Along with this, effect of sowing dates and maize cultivars on different agro-climatic indices were also calculated using formulas. Result showed that RML- 4/RML-17 produced higher kernel rows ear-1 (13.77), kernel per row (30.42) and test weight (244.9 g). Significantly higher grain yield was also found for RML-4/RML-17 (6.03 tha-1) compared to Poshilo makai-1 (4.73 t ha-1), Arun-2 (3.55 t ha-1) and Local (2.92 t ha-1). Earlier sowing date (7th April) produced higher kernel row-1 (27.97), kernel rows ear-1 (12.89) and 1000 grain weight (230 g). Significantly higher grain yield (5.13t ha-1) was obtained in earlier sowing date (7th April). Although the mean ambient temperature during research period was increasing with delayed sowing, days to attain different phenological stages decreased with late sowing. The statistically similar GDD was recorded for different sowing dates and higher PTI values were noticed with delay in planting. Similarly, heat use efficiency (HUE) was found higher in early sowing date. Arun-2 had small reduction in HUE so, it can be considered stable and best cultivar among the tested cultivars.

An experiment was carried out at the Olericulture field of Horticulture Research Centre of BARJ, Joydebpur, Gazipur during September 2006 to April 2007 to investigate yield and yield attributes of sweet pepper as influenced by plant spacing and sowing time. There were altogether 21 treatments comprising seven sowing dates viz. 1 September, 15 September, 1 October, 15 October, 30 October, 15 November, 30 November and three spacings viz. 50 × 50 cm, 50x40 cm, and 50 × 30 cm. The experiment was laid out in a Randomized Complete Block Design (factorial) with three replications. The results of the experiment showed that majority of the yield and yield components significantly varied with variation of spacing and sowing time. Only number of fruits per plant and fruit yield per plant resulted significantly higher which reflected higher yield for 1 October sowing. The number of branches per plant, number of fruits per plant, fruit length, individual fruit weight, yield per plant were found significantly increased with the increasing plant spacings but other parameters were found to be significantly increased with the decreasing plant spacing. The combined effect of sowing date and plant spacing also had significant effect on different growth and yield parameters and yield. The highest yield (19.36 t/ha) of fruit was recorded from the earlier sowing (1 October) with the closest spacing (50 × 30 cm). But reasonable yield could be obtained up to 30 October with same spacing. Keywords: Sowing time and plant spacing; yield and yield attributes; sweet pepper.

Poor early growth and uneven crop establishment are reported as the major bottlenecks in wide-scale adoption and optimal yield realization of dry direct-seeded rice (DSR). Seed priming can potentially help overcome these problems in DSR. Therefore, laboratory and field studies were conducted at Punjab Agricultural University, Ludhiana, India, during kharif/wet-season 2018 and 2019 to evaluate the effect of different priming techniques on germination, establishment, growth, and grain yield of rice under DSR conditions. The following priming treatments were evaluated: dry non-primed seed (control), hydropriming with distilled water, halopriming with 2.0% potassium nitrate, hormopriming with 50 ppm gibberellic acid (GA3), and osmopriming with polyethylene glycol (PEG)(−0.6 MPa), each with 12 and 24 h priming duration. In 2019, priming treatments were tested under two DSR establishment methods—conventional DSR (sowing in dry soil followed by irrigation) and soil mulch DSR (locally known as vattar DSR) (sowing in moist soil after pre-sowing irrigation), whereas in 2018, priming treatments were evaluated under conventional DSR only. In both years, halopriming and hormopriming resulted in a 7–11% increase in rice yields compared to non-primed dry seed (control). Osmopriming resulted in a 4% yield increase compared to control in 2018 but not in 2019. The higher yields in halopriming and hormopriming were attributed to higher and rapid germination/crop emergence, better root growth, and improvement in yield attributes. Priming effect on crop emergence, growth, and yield did not differ by DSR establishment methods and duration of priming. Conventional DSR and soil mulch DSR did not differ in grain yield, whereas they differed in crop emergence, growth, and yield attributes. These results suggest that halopriming with 2.0% potassium nitrate and hormopriming with 50 ppm GA3 has good potential to improve crop establishment and yield of rice in both conventional and soil mulch DSR systems.

The experiment was conducted to determine the effect of irrigations and sowing dates on growth and yield performance of wheat in the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of November 18, 2012 to March 30, 2013. The experiment was comprised of two factors, viz. factor A: two irrigations namely irrigation (I) and no irrigation i.e. control (I0), and factor B: three sowing dates such as S1: 1st sowing on 18 November, S2: 2nd sowing on 03 December and S3: 3rd sowing on 18 December. The experiment was laid out in a split plot design with three replications. Irrigation was assigned in the main plot, while sowing time was in the sub-plots. Data on grain yield and different yield contributing characters were taken after harvest. Results indicated that the highest grain yield was obtained with I (2.915 t ha-1) and S1 (2.983 t ha-1). The interaction of irrigation (I) and sowing on 18 November (S1) showed the maximum yield (3.387t ha-1), spike length (17.08 cm), 1000 grain weight (43.4 g), spikelets spike-1 (20.03) and grain spike-1 (65.58) of wheat.The Agriculturists 2016; 14(2) 77-85

The experiment was conducted to find out the morpho-physiological variability in response to different sowing dates in four lines of Quality Protein Maize (QPM) in in the Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh. The study was carried out with four lines of maize and two sowing dates, 15 November (T1) and 15 December, ((T2). Sowing date differed significantly in plant height, length of leaf blade, length of leaf sheath, leaf breadth, cob length, cob diameter, length of tassel, days to 50% tasselling, days to 50 % silking, days to maturity, number of cobs per plant, cob weight, number of grain per cob. 1000-seed weight, percent underdeveloped cob, total dry matter and grain yield, but did not differ in number of leaves and protein percent. The lines differed significantly among themselves in those characters except number of leaves per plant, length of leaf sheath, cob length, cob diameter, days to 50% tasselling, number of cobs per plants and number of grain per cob. The line Across 8666 (V2) and (V3) gave the highest grain yield 4.57 and 4.55 and the lowest from (V4) lines 4.41 tons per hectare. The 15 November sowing time (T1) gave the highest grain yield 4.86 tons per hectare. In case of interaction, the earlier planting time (T1) showed better performance with all lines. On the other hand, the highest yield was found from combination of line V2 and V3 with earlier planting time (T1).J. Environ. Sci. & Natural Resources, 10(1): 117-124 2017

A 3-year study was conducted to measure the effect of sowing time and seeding rate on the development and yield of wheat (Triticum aestivum L.) grown under high-yielding conditions in north-eastern Victoria. A range of wheat cultivars with different development responses, including 'winter' types, was used in 2 experiments in each season. High grain yields for dryland wheat were measured in the first 2 seasons (1985-86), and in 1985, near-optimal water use efficiencies (>18 kg/ha. mm effective rainfall) were obtained. In the third season (1987) grain yield was limited by adverse climatic conditions-in the me- and post-anthesis period. In each season, grain yield declined with delay in sowing time. In 1985 there was a loss of 200-250 kg grain/ha for each week's delay in sowing time. In 1987, yield loss with delayed sowing was 50-110 kg grain/ha. In each season, cultivars with late or midseason maturity development gave the highest mean yields, and the use of these maturity types allowed earlier sowing, in mid April. However, with late sowing of wheat there was a trend for early maturity types to give higher yields, and so the use of 2 wheat cultivars with distinct maturity development responses to climate is recommended. If only 1 wheat cultivar is to be used, then a late maturity type is recommended. Higher wheat yields were also obtained as spike density increased, as a result of higher seeding rates. Our data suggest that in the higher rainfall region of north-eastern Victoria, a spike density of about 500 spikes/m2 is required to optimise wheat yields.

A two years field study according to split plot design was conducted to investigate the impactof crop residue (CR) incorporation and P application (0, 40, 80, 120 kg P2O5/ha) on P use efficiency andyield of direct seeded rice (DSR) and wheat grown under saline soil (ECe = 4.59 dS/m; pHs = 8.38;SAR = 6.57 (mmolc/L)1/2; extractable P = 4.07 mg/kg; texture = sandy clay loam), during the years 2011and 2012. Planting of DSR (with and without crop residue incorporation @ 2 tonnes/ha) were placed inmain plots and P application was in sub plots. Data on tillering, plant height, panicle length, 1000 grainweight, paddy and straw yields were collected. On an average of two years, maximum tillers (18), paniclelength (33), grain/panicle (121) and paddy yield (3.26 t/ha) were produced with P application @ 80 kgP2O5/ha along with CR incorporation. Similarly in case of wheat grown after DSR, maximum tillers (17),spike length (17), grains/panicle (66) and grain yield (3.56 t/ha) were produced with P application @ 80 kgP2O5/ha along with CR incorporation. Although, the growth and yield contributing parameters with thistreatment (80 kg P2O5/ha + CR) performed statistically equal to 120 kg P2O5/ha without CR incorporationduring both the years, but on an average of two years, grain yield of DSR and wheat was significantlysuperior (22 and 24%, respectively) than that of higher P rate (120 kg/ha) without CR. Overall, continuoustwo years CR incorporation further increased (17%) paddy yields during the follow up year of crop harvest.Higher P use efficiency and concentrations of P, K+ and Ca2+ in both DSR and wheat plant tissues wasfound where 80 kg P2O5/ha was applied along with CR incorporation or 120 kg P2O5/ha alone while Na+and Mg2+ concentration decreased with CR incorporation and increasing P rate. An increasing trend inDSR paddy and wheat grain yields was observed with increasing the rate of P application without CRincorporation, however, it was not as much as that of 80 kg P2O5/ha application with CR incorporationand found to be superior than rest of the treatments during both study years.

The Indo-Gangetic plain (IGP) is an environmentally susceptible, communally momentous and economically tactical sphere of India where landscape, ground water and soil fertility are threatened by climate change. An increasing water scarcity for rice in the irrigated IGP is urging farmers to espouse water saving technologies such micro irrigation. Rice growing with drip irrigation may substantially reduce irrigation water requirement of rice. In order to make assessment of drip irrigation in rice, a field experiment was carried out at Pantnagar, Uttarakhand in 2017. Rice was established by Direct Seeding in conventional and drip irrigation treatments. The treatments were laid with drip irrigation at 50, 75 and 100% CPE on each 2 and 4 days interval. Two conventional irrigation practices (i.e. absolute control and farmers’ practice) were also included in the study. The experiment was laid out in randomized block design with four replications. Compared with farmers practice, (transplanted and flooded) drip irrigation at 100% CPE on two days interval produced taller shoots and higher yield attributes of rice crop. Rice grown in drip irrigation was found more grain yield than farmers’ practice. Among drip irrigation, 100% CPE on 2 days gap (T5) recorded 45% higher grain yield (5800 kg ha-1) than farmers practice. Similarly, T5 treatment was higher content and uptake of nutrient. However, treatments T3 (50% CPE on 2 days gap) followed by T7 (75% CPE on 4 days interval) had higher water use efficiency. Result, further revealed that fertilizer use efficiency of T5 treatment was found to be higher (23.2 kg grain per kg fertilizer applied). Hence, rice is scheduled with drip irrigation at a tune of 100% CPE on 2 days interval can benefit over sustaining the direct seeded basmati rice productivity. However, there is a demand to examine these benefits of drip irrigation in rice in relation to the viability of adoption by farmers.

The experiment was conducted at the Sher-e-Bangla Agricultural University (90o22 E, 23o 41 N), Dhaka, Bangladesh in  Rabi (winter) season of 2017-2018 to study the effects of sowing date on  growth and  yield of four white maize genotypes, viz.  PSC-121, Yangnuo-7, Yungnuo-30 and Changnuo-6. Sowing dates were November 26, December 11, and December 26. Data were collected on different phenological growth stages, dry matter, physiological attributes, yield, and yield attributes. A delay in sowing date delayed the time required for seedling emergence, to reach the 6-leaf collar, maturity stage, and also reduced yield. The planting of PSC-121 in November 26 gave the highest dry matter plant-1, the number of grains cob-1, and 100- grain weight that resulted in the highest grain yield (11.65 t/ha) of the genotype.
