Description A field experiment was conducted during kharif 2006 on clay loam soil, medium in
organic carbon, low in available nitrogen, high in available phosphorus and potash at Rice
Research Station, Kaul, Kaithal districts of Haryana state. The experiment consisting of
combinations of six main plot treatments viz., Control (no fertilizer), Green manuring, 7.5 t
ha-1 Press-mud, 15 t ha-1 FYM, RF + 5 t ha-1 FYM and RF (recommended fertilizers) with
two sub-plot treatment of varieties (HKR 126 and Taraori Basmati) was laid out in Split-plot
design with four replications. The experiment was carried out with the objectives of to study
the effect of nutrition sources on growth, yield and yield attributes, quality of rice and nutrient
uptake in rice including the economics of different treatments and fertility status of soil. Plant
height, number of tillers and dry matter accumulation of rice increased significantly with
application of RF + 5 tons FYM and Green manuring. Taraori Basmati produced maximum
dry matter accumulation under GM treatment while HKR 126 produced highest dry matter
accumulation under RF + 5 tons FYM. LAI of two varieties increased up to 60 DAT and
maximum LAI was recorded under RF + 5 tons FYM. Taraori Basmati experienced lodging
with highest under GM and RF + 5 t FYM. The yield and yield attributes of HKR 126 were
significantly affected by various sources with highest recorded in GM and RF. The yield and
yield attributes of Taraori Basmati were significantly highest in 15 tons FYM and RF
treatments. The maximum number of panicles per square meter and number of filled grains
per panicle were recorded with the application of RF. The RF treatment produced significantly
higher number of grains per panicle and maximum 1000-grains weight which was superior
over control. On HKR 126, an application of N150 P60 K60 Zn25 + 5 tons FYM gave
significantly higher grain, straw and biological yields. Application of nutrients sources did not
affect the N and P concentration in grain, but affected significantly the N and P concentration
in rice straw. N, P and K uptake was higher with applied RF + 5 tons FYM and GM. Variety
HKR 126 recorded maximum N (grain and total uptake), P (straw and total uptake) and K
(grain, straw and total uptake) under RF + 5 tons FYM. Taraori Basmati recorded significantly
higher uptake of N (straw), P (grain and total) and K (straw and total) under GM treatment.
Variety HKR 126 gave maximum return under RF + 5 tons FYM (Rs. 20925/-) followed by
RF (Rs. 17985/-). Taraori Basmati gave highest return under FYM (Rs. 21586/-) followed by
RF (Rs. 20558/-). Overall, highest net return was recorded with Taraori Basmati under FYM
treatment (Rs. 21586/-). Application of all sources improved soil fertility. Application of GM
had maximum organic carbon and available P content of soil, whereas RF + 5 tons FYM
recorded highest available N and available K content in soil. In HKR 126, application of RF +
FYM gave maximum hulling percentage and HRR (%) but milling percentage and cooking
time were maximum under GM treatment. In Taraori Basmati, maximum of hulling
percentages and density were recorded under GM, milling (%) under FYM, HRR, L/B ratio,
optimum cooking time and swelling index under RF + 5 tons FYM and water uptake ration
under RF.
