“…In field 1, the highest 1000 grain weight was found in T 5 treatment. Similar results, Nori et al [21] conducted that, Nitrogen, P, K affect rice production and its physiological activity. The lowest grain weight of 21.6 gm was found in T 1 (control) treatment having no fertilizer.…”

The study was undertaken to evaluate the efficacy of NPK briquette for increasing the yield of jhum rice. Two experiments were conducted at Ramery para, Bandarban sadar, Bandarban hill district in Chittagong under the AEZ 29 (Northern and Eastern Hills Tract) during March 2017 to November 2017 to study the effect of NPK briquette on growth and development of Jhum rice. In this experiment, Jhum rice was used as the test crop. The experiment was conducted in two field and designed on Randomized Completely Block Design (RCBD). The treatments consisted of 7(seven) levels of NPK briquette i.e. T1: Control, T2: 100% RFD (267.5 kg ha-1), T3: 120% RFD (320.8 kg ha-1), T4: 80% RFD (214.1 kg ha-1), T5: 100% NPK briquette (267.5 kg ha-1), T6: 120% NPK briquette (320.8 kg ha-1), T7: 80% NPK briquette (214.1 kg ha-1). Ratio in 100 kg NPK briquette contain 50 kg urea: 30 kg TSP: 20 kg MoP and RFD value was N 60 kgha-1, P 20 kg ha-1 and K 30 kg ha-1. The growth and yield of Jhum rice were significantly influenced by different levels of NPK briquette. The highest plant height of jhum rice (138.3 cm), effective tillers hill-1 (16.03), panicle length (30.10 cm), highest number of filled grain panicle-1 (202.8), 1000 grain weight (27.67 gm), straw yield (4.13 t/ha) and grain yield (3.54 t/ha) were found from T5 treatment receiving 100% NPK briquette (267.5 kg ha-1) and for all cases lowest results were found in T1 treatment receiving no fertilizer (control). Yield of Jhum rice mainly vary with RFD and NPK briquette but highest yield obtained from NPK briquette treatment compared with control.

“…Similarly, Nori et al . (2008) noted that increasing N fertilization level markedly decreased in vitro true organic matter digestibility of the rice stem fraction. Previous studies have also reported that urea N fertilization decreased IVDMD, though it increased CP and NDF contents of tall fescue (Bélanger et al 1992), vetch grass and legume species (e.g.…”

SUMMARYA completely randomized experiment for planting highland barley in 36 field plots of the Lhasa Agricultural Experiment Station was applied to investigate the effect of urea nitrogen (N) fertilization levels of 0 (control), 156, 258, 363, 465 and 570 kg/ha on nutrient accumulation, in vitro rumen gas production and fermentation characteristics of highland barley straw (HBS). Each urea application was divided into three portions of 0.4, 0.3 and 0.3 and sequentially fertilized at seeding (growth stage (GS) 0), stem elongation (GS 32) and heading (GS 49), respectively. The maturity stage lasted 5-13 days longer in response to the urea N fertilization compared with the control. After removing grains, HBS biomass was harvested at maturity. The biomass yields of leaf, stem, straw and grain were increased quadratically with increasing urea N fertilization, and HBS and grain yields peaked at the estimated urea N fertilization levels of 385 and 428 kg/ha, respectively. The increase of urea N fertilization increased the accumulation of crude protein, cellulose and lignin, and decreased the content of ash and hemicellulose in HBS, resulting in a decrease of the energy content available to be metabolized. After incubating HBS for 72 h with rumen fluids from lactating cows, the urea N fertilization decreased in vitro dry matter disappearance and cumulative gas production, and slightly altered fermentation end-gas composition. Urea N fertilization decreased microbial volatile fatty acid production, but did not alter the ratio of lipogenic acetate and butyrate to glucogenic propionate. In a brief, the current urea N fertilization strategy promoted the growth of the highland barley and increased biomass yield, protein and cellulose accumulation of HBS. A urea N fertilization level ⩽385 kg/ha could be sufficient for growth of highland barley in Tibet without a consequent nutritive reduction in ruminal digestion.

“…In Table 6 and Table 7, the CP concentrations of barley straws and grains were two to three times higher than those reported in the feed composition tables of NRC (1984) [6]. It was observed by Hollena et al (2006) [7] that the cereal cultivars were significantly influenced by the nitrogen fertilization during their growing period. The rice straws grown under the additional nitrogen fertilization had almost double the concentration of CP compared to fertilization without or low N (Hollena et al, 2006).…”

Increased agricultural production under the harsh environmental conditions with limited water resources and scarce natural resources is a major challenge in arid regions like Kuwait. The implementation of sustainable agricultural practices holds paramount importance in delivering better agricultural environment for increased production. Barley (Hordeum vulgare) is one among the most dependable cereal crops under saline and drought conditions. Mutant barley genotypes that have evolved under stress conditions using the improved genetic resources have the desired morphological, physiological and agronomic traits. As Kuwait lack local barley genotypes, it is important to find suitable barley genotypes adaptable to drought and salinity, with high crop water productivity. In this study, several mutant barley varieties were screened for better performance under drought and salinity, with high feed quality. The growth performance and the nutritive value of twelve different barley cultivars were evaluated under both fresh and brackish water irrigation in Kuwait. The seeds of the superior lines were multiplied for fodder production trials and their nutritive value was evaluated in animal production systems. It was found that two parental lines Gustoe and California Marriot and two mutant barley genotypes ari-e.228 and Golden Promise produced high grain yield of 3-4 ton/ha. The mutant genotype Golden Promise was the most tolerant, while ari-e.156 was the most susceptible genotype to saline stress. Both proximate analysis and animal feeding trial showed that the dry matter content of the air dry straws varied from 91.26% to 93.35%. The crude fat contents were within the acceptable range (1.13% to 1.93%), and high concentrations of ash and crude protein were found in straw in all genotypes. Thus, the evolution of farming systems that are economically viable, competitive, sustainable and environmental friendly improves the production efficiency, productivity and product quality of various crops.
