The water saving technology for lowland rice cultivation was very crucial because of in the future irrigation water become scarce and competed with other sectors. The lowering of the availability of irrigation water had the impact for sustainability of rice production. The review of the paper described the pattern of basic water requirement, yield responses of several lowland rice varieties to moisture stress, days interval irrigation and the alternatives of water saving techniques for improving yield and water productivity. The pattern of the actual water requirement (ET+P&S) showed the maximum value of 8.8 mm/day (1.02 lt/sec/ha) for high yielding varieties (HYV) that occurred from heading to 50% flowering. Under limited water supply, irrigation water should be applied that period to prevent yield loss. Soil moisture stress at moderate level (- 0.5 bar) from heading to full flowering was significantly decreased yield about 30% when compared with the yield of continuously flooded 3 cm depth. This period was a critical period of HYV to soil moisture stress. For rotational irrigation purposes, information of the optimum days interval irrigation was important. It was found that 3 days irrigation interval was a critical limit for HYV to achieve higher yield. The SRI model of rice cultivation had the lowest rice yield in the lowland soil, poor drainage, clay soil texture and low permeability. The modified irrigation of the SRI plus fertilizer N based on LCC readings gave a greater yield as well as water productivity. The hybrid and NPT line rice varieties had higher yield components and grain yield than Ciherang variety. Ciherang variety was not favor to grown for the wet season, it was more productive when grown in dry season even with AWD irrigation model. The plant spacing of 25 cm x 25 cm gave higher number of panicle/hill and number of spikelet/panicle under both AWD and continuously flooded 3 cm depth for dry and wet season consistently. The fertilizer N management based on SSNM with low and high rates for the early vegetative stage were not significantly affected all yield components and grain yield. The AWD irrigation could save irrigation water about 18% when compared to the continuously flooded conditions.The grain yield of the hybrid, inbred and NPT line rice varieties was higher for the dry season than wet season under both AWD irrigation and continuous flooding consistently.

Irrigation Treatments

This research was conducted in Bursa, Marmara region, Turkey, in order to determine grain yield and some morphological traits which affect the silage maize response to different irrigation water amounts. The grains’ percentage of crude oil and of crude protein were determined. Field experiments were planned following randomized complete block design with three replications and included six irrigation treatments. Irrigation treatments were created as water levels of pan evaporation (Epan) applied via drip irrigation [1.25 × Epan (I125), 1.00 × Epan (I100), 0.75 × Epan (I75), 0.50 × Epan (I50), 0.25 × Epan (I25) and 0 × Epan (I0)]. The highest value of grain yield was found to be 18,268 kg ha-1 in the I125 treatment, which represents excessive water. A quadratic relationship between grain yield and irrigation water applied was obtained. Deficit irrigation decreased grain yield and yield components except the percentage of crude oil and crude protein of grain, but improved the efficient use of irrigation water. Relationships between the grain yield and each yield component were positively significant. The highest correlation coefficient in the research gave the relationship between grain yield and plant height (r=0.957**). The results revealed that 1.25 × Epan and 1.00 × Epantreatments are preferable for higher yield. The results of this study also suggest that if water is limited, the application of 0.75 × Epan can be recommended as optimal treatment, because the best compromise among yield, yield components, quality and irrigation water use efficiency for maize was achieved with this application.

An experiment was carried out at Bangladesh Agricultural University, Mymensingh to evaluate the effect of urea super granule (USG) as a source of nitrogen on the yield and yield components of transplant Aman rice cv. BRRI dhan39, BRRI dhan46 and BINA dhan7. Five levels of N (viz., 0, 60, 120 kg ha-1 as prilled urea and 60 and 120 kg ha-1 as USG) were taken as experimental treatments. The experiment was laid out in a randomized complete block design with three replications. Plant height, effective tillers hill-1, grains panicle-1 and grain yield varied significantly due to different cultivars. All the yield and yield components except 1000-grain weight were influenced significantly by the levels of nitrogen fertilizer. The highest grain yield (4.82 t ha-1) was recorded in BINA dhan7 and the lowest one (4.30 t ha-1) was recorded in BRRI dhan39. Nitrogen @ 120 kg ha-1 as USG performed the best among the treatments in respect of yield and yield components of rice. The highest grain yield (5.46t ha-1) was obtained from BINA dhan7 with 120 kg N ha-1 as USG which was statistically identical with 60 kg N ha-1 as USG. A considerable amount (31.25%) of prilled urea (PU) nitrogen could be saved by using USG. It may be concluded that USG could be used as N management to achieve better nitrogen use efficiency in reducing N loss than the PU.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19095 Progress.

An experiment was conducted at Agronomy Field Laboratory of Rajshahi University to evaluate the effect of variety and weeding regime on yield and yield components of wheat. Four varieties viz. Prodip -V1, Gourab -V2, Shatabdi -V3, Bijoy -V4 and five weeding regime viz. a) No weeding -W0, b) Weed free -W1, c) One hand weeding at 20 DAS -W2, d) Two hand weeding (1st at 20 DAS and 2nd at 42 DAS) -W3 and e) Lintur 70 WG @ 250 g ha-1 -W4 were included as treatments in the experiment. The experiment was laid out in a Split-plot Design with three replications. The results revealed that Prodip produced the highest grain yield (5.33 t ha-1) followed by Gourab (4.85 t ha-1), while the lowest grain yield (3.98 t ha-1) was obtained from Shatabdi. The highest grain yield (5.09 t ha-1) was obtained in Weed free (W1) followed by W3 (Two hand weeding) (4.89 t ha-1) and the lowest grain yield (4.13 t ha-1) was obtained in no weeding treatment (W0). The highest grain yield (5.64 t ha-1) was obtained from the combination of Prodip and weed free treatment (V1W1) and the lowest (3.57 t ha-1) was obtained from the combination between Shatabdi and no weeding treatment (V4W0).DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14800 J.
