A field experiment was conducted under late planted lowland situations during wet seasons of 2012 and 2013 at Jorhat to evaluate the performance of 3 late planted sali (kharif) rice varieties (Prafulla, Gitesh and Monoharsali) under 3 planting dates (10, 20 and 30 September) with 2 types of seedling (Nursery seedling and double planted seedling). Results revealed that delaying planting dates from 10 September to 30 September significantly and consistently reduced both grain and straw yields along with all the yield attributing characters during both the years. On an average, the grain and straw yield reduction being 58.3 and 19.3 per cent, respectively. Among the varieties tested, rice variety ‘Monoharsali’ outyielded the variety, ‘Prafulla’ and ‘Gitesh’. Double planted seedlings of 60 days (30 + 30 days) old recorded significantly higher yields and all the yield attributes over the use of 60 days nursery seedling. The highest net return and benefit-cost ratio was recorded when rice variety, ‘Monoharsali’ was transplanted on 10 September using 60 days (30 + 30 days) double planted seedling.

The experiment was carried out at Sunamganj district during November 2016 to May 2017 to observed the effect of urea fertilizer on the yield of boro rice varieties in haor areas of Bangladesh. Two factors experiment viz. Varieties BRRI dhan29 and BRRI dhan58; and six urea fertilizer levels including: 340 (F1), 320 (F2), 300 (F3), 280 (F4), 260 (F5), and 165 kg ha-1 (F6) [Farmer’s practice (FP)] were used. In case of F1-F5, the MoP-TSP-CaS04-ZnS04 as 127-112-75-11 kg ha-1 were used while Farmers’ practice (FP) was done with only 82 kg ha-1 TSP. The experiment was laid out in two factors randomized complete block design (RCBD) with three farmers’ replications. Data were collected on growth, yield and yield contributing characters of boro rice. Plant height varied at harvest stage in relation to variety and fertilizer. The tillers production hill-1 varied at harvest in case of variety and urea application. Higher plant height was found in BRRI dhan58 (93.9 cm) in comparison to BRRI dhan29 (90.3 cm). Plant height was also influenced due to urea fertilizers application. The higher tillers hill-1 (15.9), effective tillers hill-1 (12.3) and longer panicle length (21.1 cm) were produced by BRRI dhan58 at harvest compared to BRRI dhan29. The longest panicle (21.4 cm) was produced in the treatment F3 (300 kg urea ha-1). Higher number of sterile spikelets panicle-1 (58.5) and 1000-grain weight (23.2 g) was produced by BRRI dhan58. Higher number of grains panicle-1 (137.5) was produced by BRRI dhan29. The highest grain yield (6.7 t ha-1) and straw yield (7.91 t ha-1) were obtained in the treatment F3 (300 kg urea ha-1). The experimental soil analyses showed that the nutrient contents in post-harvest soils were higher compared to initial soil due to balanced fertilizer application. It is concluded that 300 kg urea ha-1 promoted highest grain yield.

Greater attention should be paid for increasing the yield per unit area by growing modern varieties of rice through improved cultivation practices. An experiment was conducted for investigating the effect of variety and date of harvesting on yield performance of modern rice varieties during Kharif, 2012 at Agricultural Research Station, Bapatla. The experiment was laid out in a split-plot design with three replications. Main treatments comprised of four rice varieties namely, BPT 5204, BPT 2270, BPT 2231, NLR 34449, NLR 28523 and MTU 1010 and sub treatments comprised of three time of harvesting viz., 25, 30 and 35 days after flowering. Plant growth, yield attributes, yield and quality of rice varieties were significantly influenced by different dates of harvesting. BPT 2270 was found significantly superior to all other varieties in respect of effective tillers, grains panicle-1, grain yield, straw yield and hulling per cent, milling per cent and head rice recovery. Among three harvesting times, the highest grain yield (6250 kg ha-1) and straw yield (7314 kg ha-1) were obtained when the crop was harvested at 30 days after flowering. The interaction effect of variety and date of harvesting was significant in respect of grain and straw yield. The highest grain yield (7771 kg ha-1) was observed in BPT 2270 when harvested at 30 days after flowering. Therefore, optimum date of harvesting for higher grain yield may be 30 days after flowering for avoiding immature stage as well as shattering loss.

The objective of this study was to evaluate the responses in grain yield and zinc concentration of wetland and upland rice varieties to Zn fertilizer application and different growing conditions. The wetland (Chainat 1; CNT1) and upland (Kum Hom CMU; KH CMU) rice varieties were grown under waterlogged and well-drained soil conditions with or without Zn fertilizer application. Zinc fertilizer (ZnSO4) was applied at 0 and 60 kg ha−1 in three stages at tillering, booting, and flowering. In the wetland variety, CNT1, grain yield decreased by 18.0% in the well-drained soil compared to the waterlogged conditions, but there was an 8.9% decrease in grain yield in the waterlogged soil compared to the well-drained soil in the upland variety, KH CMU. Applying Zn fertilizer affected yields differently between the varieties, decreasing grain yield by 11.9% in CNT1 while having no effect in KH CMU. For grain Zn concentrations in brown rice, applying Zn fertilizer increased Zn concentration by 16.5–23.1% in CNT1 and KH CMU under both growing conditions. In the well-drained soil, applying Zn fertilizer increased straw Zn concentration by 51.6% in CNT1 and by 43.4% in KH CMU compared with the waterlogged conditions. These results indicated that the wetland and upland rice varieties responded differently to Zn fertilizer application when grown in different conditions. Applying Zn fertilizer in the appropriate rice variety and growing conditions would help farmers to improve both the desirable grain yield and Zn concentration in rice.

The soybean varieties Lee, Forrest, Bragg and Dodds were studied in zinc fertilization experiments at three sites in central and north-west New South Wales. At each site foliar sprays of ZnSO47H2O were applied before flowering. At Narrabri one spray of 4 kg ha-1 gave a yield increase of 13%. At Trangie and Breeza, two sprays each of 4 kg ha-1 increased yield by 57% and 208%, respectively. Lee was the least responsive variety at each site and Dodds or Forrest the most responsive to applied zinc. Zinc fertilizer increased plant height, foliar zinc concentration, oil content (at two sites) but decreased leaf phosphorus content. Leaf concentrations of phosphorus in untreated plots were indicative of varietal sensitivity to zinc deficiency both within and between sites. The yield increases at Narrabri were obtained even though no visual symptoms were observed. Improvement of soybean yields with zinc fertilizer in seemingly healthy crops is worthy of further investigation.
