Light textured acid soil with conventional culture of growing crops faces poor germination due low moisture retention with infrequently quandaries like restricted activity of salutary soil micro-organisms and ultimately poor yield. To combat these soil health problems and to ameliorate the overall productivity of northern Bengal region an experiment was done at Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, with split-split plot design having two main-plot and two subplot mulching treatments and four sub-sub plot nutrient management treatments. The observations with conservation techniques on three year studies overcome the quandaries and showed positive cognation between soil moisture and germination. Difficulty with establishment of maize and reduced yield was additionally solved with soil health benefits.

Phosphorus and boron are required for growth and development of black gram, and play an important role in the uptake of other nutrients such as N and K. The availability of P and B is less in acid soil because of fixation and leaching losses. Therefore, a field experiment was conducted to investigate the influence of P and B on N and K uptake in black gram with four levels of phosphorus (0, 25, 50, 75 kg ha-1) and four levels of boron (0, 0.5, 1.0, 1.5 kg ha-1) comprising of 16 treatments. The trail was laid out in split plot design and replicated three times. Phosphorus was used as main plot and boron as sub-plot. Significantly highest nitrogen concentration in black gram seed was observed at P75B1.5 as 3.82%, whereas in straw, it was observed at P75B1 as 1.75%. However, significant nitrogen uptake by seed and straw was recorded as 43.85 and 39.55 kg ha-1 at P75B1.5, respectively. Similarly, significantly highest potassium concentration in seed and straw was observed at P75B1.5 as 1.13% and 1.64%. Significant highest uptake of K by seed and straw was recorded at P75B1.5 as 13.00 kg ha-1 and 36.86 kg ha-1, respectively. Therefore, 75 kg P2O5 and 1.5 kg B ha-1 is considered optimum for achieving higher nitrogen and potassium uptake by black gram in acid Inceptisol of Meghalaya.

Pigeon pea [Cajanus cajan (L.) Millsp.] is the rich sources of dietary protein, carbohydrate & certain minerals but its poor yield needs to formulate a nutrient management practices for higher productivity in upland alfisols of Tripura and to combat it, an experiment was conducted during three consecutive kharif seasons at College of Agriculture, Lembucherra, Tripura comprising of two levels of Lime (150 and 200 kg ha-1) in main plot and two levels of molybdenum seed treatment (0 and 4g kg-1 of seed) in sub plot and 4 levels of recommended doses, viz., 0% of RDF ha-1, 50% of RDF ha-1, 75% of RDF ha-1 and 100% of RDF ha-1 (Recommended dose @ 20:60:40 of NPK). It was revealed that by the use of 100% RDF ha-1 with 150 kg ha-1 lime and 4g kg-1 of molybdenum seed treatment leads to higher yield and return per rupee respectively. But by the use of 100% RDF ha-1 with 200 kg ha-1 lime and 4g kg-1 of molybdenum seed treatment, return per rupee was recorded at 2.98. The investigation reflects that by the use of 75% RDF ha-1 return per rupee (3.78) was less compared to 100% RDF ha-1 but significant with saving the cost of 25% RDF ha-1 and soil health from the excessive use of fertilizer for sustaining the agricultural growth.SAARC J.

<p><em>Mountain microorganism</em> (MM) merupakan kumpulan dari berbagai mikrobe menguntungkan yang ditemukan pada tanah yang masih virgin pada serasah yang ada di pegunungan. Tujuan penelitian ini adalah mengetahui efikasi MM sebagai bioactivator, biofermented, dan biopestisida untuk meningkatkan hasil cabai dengan menggunakan teknologi LEISA. Penelitian dilaksanakan di Ciamis, Jawa Barat mulai bulan Mei sampai dengan bulan Desember 2016. Rancangan penelitian yang digunakan adalah Rancangan Petak terpisah dengan empat ulangan. Faktor utama adalah pengelolaan hara (a = kompos + EM4) dan (a = kompos + MM + BF) 12. Subplot adalah dosis NPK (b = 1.000 kg/ha NPKdan b = 625 kg/ha NPK), dan sub-subplot adalah cara pengendalian OPT (c1= 12 konvensional dan c2 = biopestisida MM). Hasil penelitian menunjukkan bahwa pemberian MM pada kompos dapat meningkatkan pertumbuhan (tinggi dan lebar kanopi) tanaman cabai sebesar 2 – 8 cm, dapat meningkatkan jumlah buah, jumlah bunga, jumlah cabang, dan bobot buah serta mampu meningkatkan produktivitas cabai sebesar 7,20% hingga 12,5%. Pemberian kompos + MM dapat memperbaiki kesuburan kimia, sifat fisiko-kimia dan biologi tanah sehingga lebih sesuai untuk budidaya tanaman cabai merah. Pengurangan pupuk NPK sebanyak 37,5% tidak memberikan pengaruh yang nyata terhadap peningkatan produktivitas cabai merah dan komponen hasil lainnya. Penggunaan MM sebagai biopestisida dapat menghambat perkembangan OPT dengan efikasi setara dengan penggunaan insektisida sintetik.</p><p><strong>Keywords</strong></p><p>Mikroorganisme pegunungan (MM); Pupuk kimia;, Biopestisida; Cabai; LEISA</p><p><strong>Abstract</strong></p><p>Mountain microorganism (MM) is a collection of various beneficial microorganism that was found in virgin soils or forest decomposing organic matter, used in the preparation of bokashi, bioferments, and biopesticides. The objective of this experiment found the efficacy of MM as bioactivator, bioferments, and biopesticide to increase the yield of chili pepper under LEISA technology. The experiment was conducted in Ciamis, West Java from May to December 2016. The experiment arranged in a split-plot design with four applications. Main plot was nutrient management (a1 = compost + EM4) and (a2 = compost + MM + BF). Subplot were dose of NPK (b1 = 1,000 kg/ha of NPK, b2 = 625 kg/ha of NPK), and sub-subplot were control of pest and diseases (c1= conventional and c2 = biopesticide). Result of this experiment showed that the used of MM on compost can increase growth (height and width of the canopy) pepper plants of 2-8 cm, the amount of fruit, flower number, number of branches and fruit weight and increase production chili at 7.20% until 12. 15%. The use of compost + MM can improve the fertility of chemical, physicochemical properties, and biological soil, making it more suitable for the cultivation of chili pepper. Reduction of NPK fertilizer as much as 37.5% do not provide an effect on productivity improvement and the other components of yield. Efficacy of MM as biopesticide similar to synthetic pesticide and could reduce plant damage due to pest and diseases.</p>

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.

A Field trial was conducted at the aerobic rice experimental field of the NationalCereals Research Institute (NCRI), Badeggi, Nigeria (9 ° 04 N and 6° 7 E)in 2007 and 2008 wet seasons to determine the weed competitiveness andperformance of inter Ã¢â‚¬Â and intra‐specific aerobic rice (Oryza sativa L.) varietiesunder seven weeding regimes. The trial was laid out in a split plot designwith the two varieties of rice (NERICA 1 as inter Ã¢â‚¬Âspecific and FARO 46 asintra Ã¢â‚¬Âspecific) assigned to the main plot while seven weeding regimes (hoeweeding at 25, 45, and 65 days after sowing (DAS), 25 DAS, 45 DAS, 25 and45 DAS, application of 3’,3’ Ã¢â‚¬Â dichloropropionanilide /2, 4 – Dichlorophenoxyacetic acid (orizo plus R) by Candel Company Ltd. at 3.5 kg active ingredient(ai )ha Ã¢â‚¬Â1 at 25 DAS, hoe weeding at 25 DAS followed by orizo plus at 3.5 kg aiat 45 DAS and weedy check) constituted the sub – plots. The treatmentswere replicated three times in a split plot design. From the results, interspecificvariety (NERICA1) had better weed suppression ability with highergrain yield of 3.1 t ha Ã¢â‚¬Â1 than the intra‐specific variety (FARO 46). Weed controlwas better when hoe weeding was done at 25, 45 and 65 DAS or 25 and45 DAS and at 25 DAS followed by orizo plus at 45 DAS than in other treatments.However, hoe weeding at 25, 45 and 65 DAS gave significantlygreater grain yield than other treatments. Although economic yield was obtainedfrom hoe weeding at 25 DAS followed by orizo plus at 45 DAS.
