Productivity and Economics of Hybrid Maize ( Zea mays L.) under different Fertilizer Doses in the Inner T erai Region of Nepal

Okra (Abelmoschus esculentus L.) is one of the most important vegetable crop of Nepal. Its yield and growth parameters are affected by different cultural practices. This study was conducted at Olericulture Farm of Agriculture and Forestry University, Rampur, Chitwan, Nepal during April 29 to July 9 of 2018. The field experiment was carried out in split plot design using three replications. The treatments consisted of three intra row spacing (30, 45 and 60 cm) and four different mulching materials (Silver plastic, Panicum repens, Lantana camara and bare soil). The objective of this experiment was to assess the effects of various intra-row spacings and mulching materials on growth and yield of okra. The effect of mulching materials on okra yield was found significant. The okra yield was highest (8104 kg/ha) under silver plastic mulch followed by control (5161kg/ha), Panicum repens (3901kg/ha) and Lantana camera (3701kg/ha), respectively. Silver plastic mulch enhanced the growth parameters like canopy length, plant height, leaf number, leaf length, girth and yield of okra. The spacings provided non significant effect on okra yield, however the yield of okra was highest (7295 kg/ha) under 30×30 cm spacing followed by 45×30 cm (4660 kg/ha) and 60 cm × 30 cm spacing (3703 kg/ha), respectively. Combination of silver plastic mulch along with 30 cm × 30 cm spacing provided the highest okra yield. This study suggests that farmers of the Chitwan should grow okra at spacing of 30 cm × 30 cm and under silver plastic mulch to produce higher yield.

“…Based on ANOVA result, Duncan's multiple range test (DMRT) was performed to compare the genotypes. The treatment means were compared by the Least Significant Difference (LSD) test at 5% level (Gomez & Gomez, 1984;Baral et al, 2016;Shrestha, 2019).…”

Rice (Oryza sativa) is the major cereal crop of Nepal which is being faced by the devastating rice blast disease caused by Pyricularia oryzae Cavara. An experiment was conducted to screen rice genotypes against leaf blast disease under disease conducive upland nursery at Regional Agricultural Research Station (RARS), Khajura, Banke, Nepal during July to November, 2016. A total of 101 rice genotypes (comprising of local, improved and hybrid) including resistant and susceptible check were screened in a randomized complete block design with two replications. Disease scoring was done beginning from the 20th days of sowing by using the disease rating scale 0-9. Amongst the tested 101 rice genotypes, 28 genotypes were found resistant, 15 genotypes were moderately resistant, 16 genotypes were moderately susceptible, 39 genotypes were susceptible and 3 genotypes were highly susceptible to leaf blast. The information revealed from this study could be helpful for rice leaf blast disease management and utilizing these resistant and moderately resistant genotypes for further resistance breeding program.

“…The experimental data were processed using Excel 2010 and analyzed by using Genstat 13.2. The treatment means were compared by the Least Significant Difference (LSD) test at 5% level (Gomez & Gomez, 1984;Baral et al, 2016;Sharma et al, 2016;Shrestha, 2019;Kandel & Shrestha, 2019;Jan et al, 2009).…”

Bypass protein stimulates the voluntary feed intake, increase quality milk production and thereby improves the economic status of dairy cows farming. This study was conducted to assess the effect of supplementation of bypass protein on lactation performance of dairy cattle. The experiment was conducted by using 2 factorial completely randomized designs. Milk yield of individual animal was recorded daily and milk composition was recorded at fortnight interval. Results revealed that the average daily milk yield of cows fed with Heat treated soyabean cake-T1 (4.29 L) was greater than cows fed with formalin treated soyabean cake-T2 (3.56 L) followed by control group-T3 (2.62 L). . The fortnight average milk protein and fat percentages were 2.91, 2.94 and 3.18% and 5.52, 5.55 and 4.47% for T0, T1 and T2 groups respectively. The weekly average milk SNF and milk density were 8.12, 8.37 and 8.64 % and 25.67, 27.80 and 27.10%, for group T0, T1 and T2 respectively. Experiment revealed that by-pass protein supplementation to lactating animals is one of the option for improving the milk production and milk composition and suggested that further study should be conducted to precise the optimum level of bypass protein supplementation and to quantify the experimental period.
