This document summarizes the results of a study on the productivity and quality of forage oat under varying nitrogen levels and cutting management conditions in Uttar Pradesh, India. Key findings include:
1) Higher nitrogen levels (120 kg/ha) and two cuttings resulted in greater forage yield, crude protein yield, plant height, number of tillers, and leaf area index compared to lower nitrogen levels or a single cutting.
2) Nitrogen levels of 80-120 kg/ha produced the highest green fodder yield of 63.36-79.73 t/ha and dry matter yield of 10.01-12.94 t/ha.
3) Two cuttings at

3. INTRODUCTION
Oat is the most important cereal crop grown for grain and forage purpose in winter
in north western and central India.
Oat fodder is quite nutritive containing, on an average, 7.6 per cent crude protein at
50% flowering stage and about 14.6 per cent at very early stage of growth.
It has excellent growth habit, quick recovery after cutting and good quality herbage.
Oat ranks sixth in world cereal production following wheat, maize, rice, barley and
sorghum (FAO STAT 2011)
The total area covered under oat cultivation in the country is about 500 000 ha.
The crop occupies maximum area in Uttar Pradesh (34%), followed by Punjab (20%),
Bihar (16%), Haryana (9%) and Madhya Pradesh (6%) (IGFRI 2011)
There are several factors, which affect the productivity and quality of forage oat.
Cutting management and nitrogen fertilizer play dominant role.

12. Nitrogen Management for Fodder Oat Crop
Being the exhaustive crop, Oat requires large amount of nutrients particularly N
for producing more yields.
Applications made early will ensure a canopy that is large containing high levels
of stem carbohydrate
Nitrogen is required for tiller development and required by plants to create
protein
Oat forage yield positively responses to applied nitrogen and needs ample
quantity of nitrogen for its better production.
Use of optimum amount of nitrogenous fertilizer through a suitable application
method at a time when it is most efficiently and effectively utilized is imperative.

21. Cutting Management in different growth stages of oat
Cutting stage mainly determines the ultimate fodder yields and its quality.
With the increase in age, maturity, or cutting stage, nutritive value and palatability of
the harvested fodder decreases.
To obtain the best compromise between fodder yield and quality, the crop should be
harvested at late vegetative stage.
At this stage regeneration, palatability, and quality is higher than at 50 % or 100 %
heading and also 1-2 extra cuttings and hence more fodder can be obtained.
Cutting Stages:
1. ‘Boot’ stage.
2. ‘Milk’ stage.
3. ‘Dough’ stage.
Cutting height:
The crop should always be harvested at least 4 inches from the ground level to facilitate
quick re growth.

Table 19. Effect of cutting management in different varieties of forage oat on
Leaf:stem ratio (at harvest), LAI (cm), Forage yield (q ha-1 )
35. Conclusion
Application of N @ 120 kg/ha under double cutting at 55
and 85 DAS found to be better for obtaining higher
green forage yield beside higher crude protein yield too.
