“…There is a growing practice of using hybrid seed for maize production to meet the demand of poultry feed industry, which is annually increasing at 11 percent (IFPRI, 2010;KC et al, 2015). However, there is very limited amount of hybrid seed available in Nepal which is unable to meet the growing demand of maize seed.…”

The study aimed to analyze profitability and resource use efficiency of maize seed production in Palpa district of Nepal. Raosoft Inc. software was used to determine the sample size of 182 maize seed producers from the total 260 maize seed producers in the district. Data was collected using a pre-tested semi-structured questionnaire survey administered to the randomly selected samples. Results showed that the uses as well as cost of major inputs such as seed, labor, farmyard manure (FYM),and management/other cost including tillage were higher among small scale farmers compared to the large scale farmers. The average cost of production among small scale farmers was NRs. 94,195per hectare compared to NRs. 64,145among large scale farmers. A benefit cost ratio of maize seed production was higher for large scale farmers (1.12), which in case of small scale farmers was less than 1, i.e. 0.9. Hence, maize seed production was found profitable only for large scale farmers. Resource use efficiency analysis showed FYM, tillage and labor were overused. This suggests that the use of FYM, tillage and labor should be decreased by 665, 456 and 68 percent respectively. Similarly, cost on seed, chemical fertilizer and management/other were underused, hence, need to increase by 92, 69 and 97 percent respectively for the optimum allocation of resources. Overall, maize seed production is profitable but resources should be optimally utilized and should be carried on larger scale.

“…Maize (Zea mays L.) is the second most important staple food crop after rice and a major feed crop in Nepal (KC et al, 2015). Despite the implementation of various seed related projects and active involvement of public and private institutions; still the country has been suffering from unavailability of quality seeds.…”

The study was aimed to examine the effects of various storage structures and moisture contents on seed quality attributes of quality protein maize seed. The quality protein maize (QPM-1) seed was tested in conventional seed storage containers (Fertilizer sack and earthen pot) and the improved hermetic ones (Metal bin, Super grain bag, and Purdue Improved Crop Storage (PICS) bag) at Seed Science and Technology Division, Khumaltar, Nepal during February, 2015 to January 2016. Ten treatments comprising 5 storage devices in two moisture regimes (11% and 9%) replicated thrice and laid out in Completely Randomized Design (CRD). Data on temperature, relative humidity (RH), germination, electrical conductivity (EC), seed moisture content (MC) were collected bimonthly. The conventional containers were found liable to the external environmental condition whereas the hermetic structures observed with controlled RH level below 40% in all combinations. Electrical conductivity (EC) for seed vigor showed that hermetic containers provide higher seed vigor than the conventional ones. Up to 4 months all treatments were found statistically at par for germination. A significant difference was observed in each treatment after 4 months where PICS bag & Super grain bag showed best germination followed by metal bin while fertilizer bag & earthen-pot showed poorer and poorest germination respectively till one year. Almost all treatments with lower MC showed better results than the treatments with higher MC. A negative correlation (R 2 =69.7%) was found between EC and Germination. All six figures from 2 to 12 months on MC showed statistically different where hermetic plastic bags were found maintaining MC as initial whereas MC of fertilizer bags and earthen pot was spiked than the basal figure. The finding evidenced that the hermetic containers and low MC are the seed storage approaches for retaining the quality of seed even in an ambient environmental condition for more than a year.Keywords: Seed quality, Germination, storage containers, Electrical conductivity, Moisture content 78 INTRODUCTIONMaize (Zea mays L.) is the second most important staple food crop after rice and a major feed crop in Nepal (KC et al., 2015). Despite the implementation of various seed related projects and active involvement of public and private institutions; still the country has been suffering from unavailability of quality seeds. Quality seed demand in Nepal is apparently tremendous, where lion's share of seeds are imported and country's import has been hiking each year. The official record of Seed Quality Control Centre (SQCC) in 2015 shows that 2745 metric tons of seed was traded in where 1025 million of Nepalese currency redeemed. Formal sector contributes less than 10% of seed demand whereas Informal sector, farmer-to-farmer seed exchange mechanism has been contributing 20-50% of seed demand. Seed replacement rate (SRR) for maize is below 15 % (Joshi, 2015). Hence, production and proper storage of quality seed in community level is regarded as p...

“…In the context of Nepal, the importance of maize increase with altitude, eventually standing as a staple crop in northern part of the country (KC et al, 2015). In the context of world, 58% of maize is utilized in animal feed, 16% in human food and 26% in bioethanol production (HLPE, 2013), whereas, study shows that 60%, 25% and 3% of grain were used for animal feed, food and seed respectively in the hilly district of Nepal and rest is sold to the traders (Timsina et al, 2016).…”

Biofertilizers may be a better eco-friendly option to maintain soil fertility. The study was conducted to investigate the effect of Azotobacter and Trichoderma on the vegetative growth of maize (Zea mays L.) plants. The experiment was carried out in medium sized pots, at IAAS, Lamjung (Feb 2017 -May 2017 in completely randomized design (CRD), consisting eight treatments and three replications. Treatments were namely T1 (control), T2 (Azotobacter), T3 (Trichoderma), T4 (Azotobacter + Trichoderma), T5 (NPK), T6 (Azotobacter + Trichoderma + FYM), T7 (Azotobacter + Trichoderma + FYM + NPK), T8 (FYM). Azotobacter showed a positive increase in plant height, stem girth, dry shoot weight, root length and width, and root weight while Trichoderma displayed either negative or minimal impact. Effect of FYM was lower than Azotobacter but considerably higher than Trichoderma. Trichoderma seriously inhibited the expression of Azotobacter when used together. Trichoderma even suppressed the outcome (except shoot weight) of FYM when used together. Root length was the longest in Azotobacter inoculation. The highest number of leaves was in T7 followed by Azotobacter (T2) and NPK (T5). Unlike leaf width, Azotobacter showed a negligible increase in leaves length while Trichoderma wherever present showed the negative impact. Minimum chlorophyll content was found in Azotobacter or Trichoderma after 73 days. Azotobacter treatment showed early tasseling than Trichoderma. The association of Azotobacter and Trichoderma increased the biomass. Azotobacter has significant effects on growth parameters of maize and can supplement chemical fertilizer, while Trichoderma was found to inhibit most of the growth parameters.
