Cauliflower is an important winter crop in Nepalese farming community and consumed all over the world. The yield and vitamin C content of cauliflower depends on many factors such as its genotype, cultural practices, environment in which it is growing on and storage after harvesting etc. But among them, the availability, dose and types of fertilizers used play an important role in yield and the amount of vitamin C content in cauliflower. The vitamin C is one of the major Phyto chemicals we obtained from cauliflower and it plays an important role in our physical health. The disease like scurvy is caused due to the lack of ascorbic acid known as vitamin C. It has been proved that consumption of fruits and vegetables rich in vitamin C helps in prevention of cancer and heart disease because it act as a source of antioxidant. The number of studies conducted in the past revealed that the fertilizers having higher amount of nitrogen leads to the formation of less vitamin C on the cauliflower and vice versa.

Marigold species are famous around the world and grown for its different purpose like beautification, to extract pharmaceuticals products, loose flowers, and cut as well. Among the many species of marigold Tagetes erecta L. is one of the famous species grown in Nepal. Pinching in marigold is a process of increase in flower yield through the diversion of energy through breaking apical dominance in plants. Pinching increases the flower yield (96.78 q/ha) compared to non-pinching (68.78 q/ha) (Rathore et al., 2011) in marigold.

The research on varietal screening of rice against leaf folder, caseworm and grasshopper damage was conducted during 2019 in Rampur, Chitwan to study the host plant resistant of different varieties of rice under field condition. The experiment was laid out in RCBD with three replications and seven treatments namely i) Makawanpur -1 ii) Mansuli iii) Radha-4 iv) Ramdhan v) Sabitri vi) Sama Mansuli sub-1 and vii) sukkha-3. The experiment revealed that lowest population of leaf folder, caseworm and grasshopper was recorded in variety Radha-4 followed by Ramdhan. The experiment showed the yield loss was significantly lower in Radha-4 followed by Sabitri and Ramdhan due to leaf folder, caseworm and grasshopper. So Radha-4 and sabitri would be good option in rice production for reducing insect pest damage.

The research conducted in the laboratory includes four different types of concentration of salt. The highest germination percentage was recorded with Gorakhnath followed by Jyoti Ankur and Paddy Jk with almost all solution. The highest dry weight shoot was observed on Paddy Jk and on Gorakhnath at treatment level 10gm and Jyoti Ankur and Ramdhan showed negligible growth. The highest fresh root weight was observed on Paddy Jk at all treatment level while Ramdhan showed lowest fresh weight. At dry weight of root, Paddy Jk and Gorakhnath showed highest dry weight while Sabitri and Ramdhan showed negligible growth at treatment 10gm of salt solution. And at last at root shoot ratio the highest growth was observed on treatment level 10gm salt solution because at stress condition root performs better. Thus, this reveals the germination performance of Rice (Oryza sativa) seedlings in saline condition was better with Gorakhnath followed by Paddy Jk variety while seedlings growth and development with Ramdhan was seen to be lowest. Similarly, the better performance was observed on control condition while the least performance on treatment 10gm of salt solution.
