The study was undertaken to develop optimum cutting and nutrient management schedule formaximization of quality green biomass and to study the intrinsic relationship of nitrogenapplication and nitrate accumulation in forages. The study consisted of two field trials asunder;1. Seasonal forages based round the year production systemThe study consisted of five nitrogen management modules and three harvesting intervals ofberseem. The treatments were implied on sorghum+ cowpea - berseem + chinese cabbage-maize+ cowpea system. The results indicated that During Kharif 20 II-12th application of133% of (A) to sorghum + cowpea recorded significantly maximum green fodder yield(376.0 q green or 60.9 q dry matter/ha). However, the nitrate accumulation in plants increasedupto 200% N application of (A): 4527 pm in sorghum and 7245 ppm in cowpea. During Rabiseason the application of concomitant higher doses of nitrogen increased the nitrateaccumulation in berseem plants, maximum being (4196 ppm) with 200% of (A). The biomassyield increased upto 133% of nitrogen application (583.54 q green or 78.05 q dry matter perhectare). The shortening the harvesting interval at 25 days (594.25 q green and 80.50 q dry

matter IRa) Produced higher green fodder yields than 30 days harvesting interval. But, interms of dry matter productivity it remained at par with 30 days harvesting interval (80.08q/ha).The summer crop of maize + cowpea recorded significant yield increase upto 133% ofrecommended dose of nitrogen with split application (176.60 q green and 30.25 q dry matter/ha).2. Perennial forages based round the year production systemIn the perennial grass based round the year fodder production system five nitrogenmanagement modules and four harvesting intervals were evaluated on Napier Bajra Hybrid+cowpea-berseem- cowpea system. During Kharif season two rows of cowpea was grown inthe interspaces of hybrid Napier. Both the crops responded to increase in nitrogenapplication (Table 1 & 2) upto 133% of (A) in case of biomass yield (823.2 q grass + 157.05q cowpea green or 141.6 q grass + 26.8 q cowpea dry matter/ha). As regards to nitrate contentthe maximum nitrate was recorded in plots receiving recommended dose of nutrients withsplit application of 200% N [(4337 ppm in hybrid napier grass and 6170 ppm in whole plantof cowpea (at harvest)]. The results recorded during Rabi season 2011-12, indicated that theyield of berseem grown in the interspaces of hybrid napier increased upto 133% nitrogenapplication (334.2 q green or 45.82q dry matter/ha). The maximum nitrate content in berseemplants (3822.6 ppm) was recorded with application of 200% dose of nitrogen application. Thesummer crop of cowpea was sown in the interspaces of NB hybrid. The maximum yields ofcowpea (73.71 q green or 11.94 q dry matter/ha) was recorded with application of 133% doseof nitrogen. The varying dose of nitrogen application did not affect the dry matter content ofdry matter content of plant.

The peri-urban is an interface where urban and rural activities, environment and society meet.

In these areas the farmers /Iivestock keepers' requirements are potentially more in

comparison the available resources, which encourage indiscriminate and non-judicious use of

inputs. The study was undertaken to develop optimum cutting and nutrient management

schedule for maximization of quality green biomass and to study the intrinsic rela~ionship of

nitrogen application and nitrate accumulation in forages. The study was undertaken to

develop optimum cutting and nutrient management schedule for maximization of quality

green biomass and to study the intrinsic relationship of nitrogen application and nitrate

accumulation in forages. The study consisted of two field trials as under;

1. Seasonal forages based round the year production system

The study consisted of five nutrient management modules [Recommended dose of Nutrients,

Recommended dose of Nutrients with split application of N * (A), 133% of (A), 200% ofI

(A)] and three harvesting intervals of berseem (20, 25 and 30 days). The treatments were

implied on sorghum+ cowpea - berseem + chinese cabbage- maize+ cowpea system. The

results indicated that, During Kharif 201 I_12th application of 133% of (A) to sorghum +

cowpea recorded significantly maximum green fodder yield (376.0 q green or 60.9 q dry

matter/ha). However, the nitrate accumulation in plants increased upto 200% N application of

(A): 4527 pm in sorghum and 7245 ppm in cowpea (Fig. I). During Rabi season the

application of concomitant higher doses of nitrogen increased the nitrate accumulation in

berseem plants, maximum being (4196 ppm) with 200% of (A). The biomass yield increased

upto 133% of nitrogen application (583.54 q green or 78.05 q dry matter per hectare). The

shortening the harvesting interval at 25 days (594,25 q green and 80.50 q dry matter /ha)

Produced higher green fodder yields than 30 days harvesting interval. But, in terms of dry

matter productivity it remained at par with 30 days harvesting interval (80.08 q/ha).The

summer crop of maize + cowpea recorded significant yield increase upto 133% of

recommended dose of nitrogen with split application (176.60 q green and 30.25 q dry matter

/ha).

2. Perennial forages based round the year production system

In the perennial grass based round the year fodder production system five nutrient

management modules [Recommended dose of Nutrients, Recommended dose of Nutrients

with split application of N * (A), 133% of (A), 200% of (A)] and four harvesting intervals

(20 days for NB hybrid & 25 days for berseem, 20 days for NB hybrid & 30 days for

berseem, 30 days for NB hybrid & 25 days for berseem and 30 days for NB hybrid & 30 days

for berseem) were evaluated on napier bajra hybrid+ cowpea-berseem- cowpea system.

During Kharif season two rows of cowpea was grown in the interspaces of hybrid

Napier. Both the crops responded to increase in nitrogen application (Table 1 & 2) upto

133% of (A) in case of biomass yield (823.2 q grass + 157.05 q cowpea green or 141.6 q

grass + 26.8 q cowpea dry matter/ha). As regards to nitrate content the maximum nitrate was

recorded in plots receiving recommended dose of nutrients with split application of'200% N

[(4337 ppm in hybrid napier grass and 6170 ppm in whole plant of cowpea (at harvest)]. The

results recorded during Rabi season 2011-12, indicated that the yield of berseem grown in the

interspaces of hybrid napier increased upto 133% nitrogen application (334.2 q green or

45.82q dry matter/ha). The maximum nitrate content in berseem plants (3822.6 ppm) was

recorded with application of 200% dose of nitrogen application. The summer crop of cowpea

was sown in the interspaces ofNB hybrid. The maximum yields of cowpea (73.71 q green or

11.94 q dry matter/ha) was recorded with application of 133% dose of nitrogen (Table 3).

The varying dose of nitrogen application did not affect the dry matter content of dry matter

content of plant.
