The effect of quality mulberry leaf Morus cathayana on nutrition index of silkworm Bombyx mori L. have been conducted . This research was Completely Randomized Design (CRD) by two treatments. The first treatment was mulberry plant that cultivated on soil with Urea, TSP and NPK fertilizers and the second was the plants were not fertilized l. Each treatment was replicate 20 times. The results showed that the addition of Urea, TSP and NPK fertilizer on mulberry has effect (p<0,05) on increasing of the growth rate (GR) of instar III, the consumption rate (CR) of instars III and V, and efficiency of conversion of ingested food (ECI) of instar III and V. In addition, approximate digestibility (AD) of instar III, IV were 20%, 7%, 24%, 40% and then V was 51%, 15%, 21% and 70% respectively.

Aim: The present study was aimed to see the performance of silk worm (Bombyx mori L.) double hybrid fed on leaf raised through splitting the recommended dose of chemical fertilizers. Study Design:  Completely Randomized Design (CRD). Place and Duration of Study: College of Temperate Sericulture (CoTS) Mirgund, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir (SKUAST-K), during 2017 and 2018. Methodology: The present investigation was carried out at the experimental farm of College of Temperate Sericulture-Mirgund. Goshoerami a popular variety of mulberry in the region was used for the study. Disease free layings (dfl’s) of the popular double hybrid were obtained from the Germplasm Bank maintained at College of Temperate Sericulture (CoTS) Mirgund. These dfl’s were incubated, brushed and reared up to 3rd instar en masse following the standard rearing procedure. After 3rd moult, 3 replications of 100 larvae in each treatment were maintained. Different larval and Cocoon parameters were recorded during the course of experimentation. Standard procedure was followed to record observations. The data was compiled and analyzed. Results: T11 recorded the shortest values for total larval and fifth instar larval duration being statistically at par with treatments/ fertilizer schedules T12, T9, T10, T3, T4, T1, T2 and T7. Weight of ten mature larvae was recorded higher in treatment T14 being statistically at par with treatments T13, T16 and T15 respectively. Cocoon yield per 10,000 larvae by number was recorded highest In T14 treatment, which was recorded statistically at par with treatments T13 and T16 respectively. Cocoon yield by weight was more in treatment T14 being at par with treatments T13 and T16. Pupation rate was found higher in treatment T14 being at par treatment T13. Conclusion: Double hybrid performed better under parameters like- total as well as fifth instar larval duration in case of fertilizer schedule - T11 (N3P2K1), while as in case of larval weight, cocoon yield by number and by weight and pupation rate, the hybrid performed better under T14 (N4P1K2) fertilizer Schedule.

The objective of this research was to investigate the effectiveness of combination of bio-slurry fertilizer and NPK fertilizer on the growth and production of two varieties of rice. The experiment was assigned in a completely randomized design of factorial pattern. The first factor was the combination of bio-slurry and NPK fertilizer that consisted of P0 = no added fertilizer (control) 0 ton/ha, P1 = NPK fertilizer 550 kg/ha (165 kg N, 33 kg P, 45 kg K); P2 = bio-slurryfertilizer 2.3 tons/ha (45 kg N, 14 kg P, 23 kg K) and NPK fertilizer 400 kg/ha (120 kg N, 24 kg P, 32 kg K); P3 = bio-slurryfertilizer 4.6 tons/ha (90 kg N, 28 kg P, 46 kg K) and NPK fertilizer 250 kg/ha (75 kg N, 15 kg P, 20 kg K); P4 = bio-slurry fertilizer 5.9 tons/ha (115 kg N, 36 kg P, 59 kg K) and NPK fertilizer 100 kg/ha (30 kg N, 6 kg P, 8 kg K); and P5 = bio-slurryfertilizer 8.5 tons/ha (165 kg N, 52 kg P, 85 kg K). The second factor was varieties of rice that consisted of V1 : IR-64 and V2 : Ciherang. Each treatment was repeated three times. Parameters observed were plant height, number of tillers, weight of 1.000 grains, and rice production. Data were analyzed using ANOVA and continued with Duncan’s Multiple Range Test (DMRT). The results showed that the combination of bio-slurry fertilizer and NPK fertilizer were significantlyaffect (p <0.05)all observation parameters, while varieties of wetland rice did not show significant effect on all observation parameters (p<0.05). The application of bio-slurry fertilizer in single treatment or in either combination with NPK fertilizer had the same result with the treatment of NPK fertilizer on the growth and yield of rice.

Screen house experiments were carried out to examine the effects of aqueous leaf extracts of Tithonia diversifolia (Ti) and Vernonia amygdalina (Ve), as well as NPK fertilizer (15-15-15) on the germination, growth and development of maize. Fresh leaves were collected, washed with tap water, chopped and pounded, soaked in distilled water and filtered. The two filtrates were used to prepare extracts at 50 and 100% w/v. Four maize seeds were placed in Petri dishes laid out in a completely randomized design with five replicates. In every Petri dish 10 ml of extract per treatment was added. A control experiment with distilled water was also set up. Also, in a completely randomized design with four replicates, 4-week-old potted maize plants were treated with 500 ml of each extract as well as with 1.52 g of NPK fertilizer. The results showed that the germination percentage of the seeds followed the order Ti50 - Control - Ve50. The seeds treated with aqueous extracts of T. diversifolia and V. amygdalina at 100% w/v produced lower but equal germination percentage. The seedling radicle growth was significantly inhibited by the aqueous extracts of Ti100, Ve50 and Ve100 (p?0.05). The inhibition was dose-dependent and more pronounced in seeds treated with extracts of V. amygdalina. The aqueous extract of T. diversifolia (50% w/v) and control influenced radicle growth substantially. All the extracts inhibited the plumule development compared to the control. On the other hand, growth, development and yield were not significantly affected by the plant extracts.

This research aimed to determine site specific NPK fertilizer rates combined with rice straw compost application for rice grown on the tidal lowland. This research was conducted in a greenhouse in Indralaya, Ogan Ilir, South Sumatera in February  until September 2017 using a factorial completely randomized design with two factors and three replications. The first factor was NPK fertilizer rate calculated based on the results of soil chemical analysis, consisting of five levels, namely 50% (D1), 75% (D2), 100% (D3), 125% (D4) and 150% (D5) of the site-specific fertilizer rate. The second factor was rice straw compost rate consisting of two levels, namely 5 Mg ha-1 (J1) and 10 Mg ha-1 (J2). The results showed that the application of 150% NPK rate and 10 Mg ha-1 rice straw compost resulted in the best effects on the rice growth grown on the tidal lowland. The application of those fertilizer doses produced the highest maximum number of tillers and productive tillers. In this regard the doses of NPK fertilizers that should be applied are 315 kg urea ha-1, 135 kg SP-36 ha-1 and 90 kg KCl ha-1.

The purpose of this research is to determined the effect of insecticide profenofos to the rate of consumption and assimilation efficiency of cow- dung by earthworms Pontoscolex corethrurus Fr. Mull. This research used Completely Randomized Design with 6 treatments and 5 repetition. Treatments that was given to sample are the insecticide profenofos with concentration of 0 % (control); 0.1%; 0.2 %; 0.3 %; 0.4 %; 0.5 %. Data analysis was using Varians Analysis. If there was real difference then data analysis continued with The Duncan Test on level of confidence of 95%. The results of this research show us that several concentration of insecticide carbaryl have the real effect to the average of consumption rate and the efficiency of absorption. The lowest average of consumption rate on earthworm Pontoscolex corethrurus Fr.Mull is on concentration of 0.5 % (0.23 ± 0.02 mg/g day) and the highest average of consumption 26 rate on earthworm Pontoscolex corethrurus Fr. Mull is on concentration of 0% (control) (2.53 ± 0.05 mg/g day). The lowest average of approach digestyon earthworm Pontoscolex corethrurus is on concentration of 0 % (control) (40.78 28 ± 2.56 %) and the highest average of digestion earth worm Pontoscolex corethrurus Fr.Mull is on concentration of 0.5 % 29 (70.76 ± 3.67 %).
