Soil Test Crop Response (STCR) study was conducted during 2010-11 for autumn rice under integrated plant nutrition system (IPNS) in Inceptisols (Aeric Endoaquepts) in Jorhat district of Assam. The basic parameters were computed from the STCR data, and the fertilizer prescription equations were developed for recommending fertilizer doses in autumn rice. The nutrient requirement (NR) for producing one quintal of autumn rice was found to be 2.40 kg, 0.84 kg and 2.25 kg of N, P<sub>2</sub>O<sub>5</sub> and K<sub>2</sub>O, respectively. The percent contribution of nutrients from soil (CS), fertilizer (CF) and FYM (CO) were calculated as 12.49, 45.31 and 32.92 for N, 13.42, 28.52 and 11.84 for P<sub>2</sub>O<sub>5</sub> and 21.99, 47.58 and 29.76 for K<sub>2</sub>O, respectively. These equations were validated in farmers’ fields during 2012 and the variation between actual yield and targeted yield ranged from +1.36 to +5.33.The fertilizer estimates under STCR-IPNS for 3000 and 4000 kg ha<sup>−1</sup> targeted yield recorded maximum response ratio and economic benefit in the field trial and confirmed the validity of proposed fertilizer prescription equations for autumn rice.

A pot experiment was conducted in Kharif 2009 and 2010 to study the effect of potassium humate and chemical fertilizers on growth and yield attributes of rice (Oryza sativa L). Potassium humate was applied at the rate of 0, 5 and 10 mg/kg soil along with 100 and 75% recommended dose of fertilizers NPK (60, 30, 30 mg/kg) and 12.5 mg/kg zinc sulphate was also applied. Addition of 10 mg/kg PH along with 100% NPK fertilizers and 12.5 mg/kg zinc sulphate caused significant increase in plant height, number of tillers, panicle height, panicle length, test weight, straw yield and yield of rice as compared to 100 and 75% NPK alone.

To develop fertilizer prescription equations based on soil test crop response (STCR) approach for rice-rice cropping sequence, trials were conducted at farmer’s field in Karikalampakkam village, U.T. of Puducherry, during 2015-16. Soil test data, yield and nutrient uptake by successive crops were recorded to calculate four basic parameters viz. nutrient required to produce one quintal of rice, contribution of nutrients from fertilizers, contribution of nutrients from soil and contribution of nutrients from FYM used in developing STCR based fertilizer prescription equations. The per cent nutrient contribution of nutrients from soil (CS), fertilizer ( CF) and FYM (CFYM) were found to be 19.15, 45.90 and 23.27 for N, 12.13,40.16 and 26.98 for P2O5 and 13.76, 79.64 and 41.07 for K2O respectively for rice cv. White ponni. The same for the rice cv.ADT 45 were 13.48, 40.46 and 34.26 for N, 15.81, 44.64 and 19.89 for P2O5 and 10.48, 58.64 and 41.51 for K2O respectively. Based on fertilizer prescription equations and nomograms formulated for a range of soil test values and desired yield target for the cropping sequence. It was revealed that under the treatment NPK + FYM @ 12.5 t ha- 1 , 47, 29 and 34 kg ha- 1 for rice cv.White ponni and 41 , 22 and 27 kg ha- 1 for rice cv.ADT 45 of fertilizer N , P2O5 and K2O, respectively could be saved for attaining target yield of 70 q ha- 1 compared to NPK fertilizers alone.

ABSTRACT On agriculture, efficiency measurement is based on income and outcome. Liming is the part of income that effected to soil condition and productivity. One of constraints on cultivating rice plants is low grades of soil acidity. The low grades of soil acidity could be caused from the characteristic of alluvial soil and other influences. Acid soil can results in decrease of rice yield. Liming materials can increase the grades of soil acidiy and productivity at first season to third season. The effect of liming is significant to increase soil acidity, but weakly effecting to improvement of productivity. Furthermore, production efficiency showed value of R/C ratio more than 1 and increase on every season. Thus, although liming unable to improve productivity significantly, however farming activity or cultivating is arguably efficient or productive. Keywords : Efficiency, Rice Plants, Acid Soil, Lime, Alluvial ABSTRAK Pada pertanian, pengukuran efesiensi dilihat dari pemasukan dan pengeluaran. Pemberian kapur termasuk dalam pemasukan yang dapat mempengaruhi kondisi tanah maupun produktivitasnya. Salah satu kendala dalam budidaya tanaman padi adalah nilai pH tanah yang rendah. Nilai pH tanah yang rendah dapat disebabkan dari karakteristik tanah alluvial maupun dari pengaruh lainnya. Rendahnya pH tanah sehingga tanah masam dapat mengakibatkan penurunan hasil produksi tanaman padi. Tanah masam dapat diatasi dengan pemberian kapur pertanian. Pemberian kapur pertanian dapat meningkatkan nilai pH dan produktivitas pada musim tanam pertama sampai musim tanam ketiga. Pengaruh pemberian kapur signifikan dalam meningkatkan nilai pH, namun tidak berpengaruh lemah terhadap peningkatan produktivitas. Selain itu, efisiensi produksi menunjukkan nilai R/C ratio yang lebih dari 1 dan meningkat signifikan pada setiap musim. Jadi, meskipun pemberian kapur tidak mampu meningkatkan produktivitas secara signifikan, namun kegiatan usahatani atau budidaya dapat dikatakan efisien atau layak produksi.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.
